There’s always a reason to stop and appreciate the smaller stuff in life. Since 2018, Tracy and Dan Calder have drawn attention to documenting daily minutiae with the Close-up Photographer of the Year competition, highlighting the past 12 months’ best images capturing nature, animal, underwater, and human subjects.

The 5th annual edition is no exception, with amazing glimpses of everything from slumbering frogs, to magnetic waves, to microscopic life, to rarely seen deep sea creatures. Across a wide range of categories, photographers around the world managed to snap some extremely striking images, making even some of the creepiest of crawlies look pretty cute for a change. Check out a few of our favorite finalists and winners of 2023 below, and remember to keep an eye out for the little things this year. They’re always there and worth seeing, even if you don’t have a camera in hand.

Small slime mould with ice crown atop it
Fungi 1st Place Winner: “The Ice Crown,” ‘This 1mm tall slime mould (Didymium squamulosum) was found in leaf litter on a Buckinghamshire woodland floor in January. Attracted by the way the frost had formed a crown shape on top of the fruiting body, I had to be very careful not to breathe on it. During a previous attempt with another slime mould, my breath had melted the ice when I inadvertently got too close.’ © Barry Webb | cupoty.com
Two four-spotted skimmer dragonflies mating
Butterflies & Dragonflies 2nd Place Winner: “Letting Go,” ‘‘Capturing a Four-spotted skimmer dragonfly (Libellula quadrimaculata) mating is particularly difficult because they connect and mate in-flight without any warning and for only a few seconds. The moment captured in this photo is just after the male has finished depositing his sperm on the female’s eggs and they are disconnecting. She will then attempt to deposit the eggs in the water and he will hover near her to ward off other males who would like to also mate with her.’ © Steve Russell | cupoty.com

Animals Finalist: “Picking Flowers,” ‘An Elephant enjoys a nutritional meal of water lily flowers as it makes its way across the Chobe River, Botswana. As flood water reaches the Chobe river (all the way from its starting point in Angola) the waterways are transformed with a wave of flowers.’ © William Steel | cupoty.com
Two huntsman spiders
Animals Finalist: “Pandercetes Sp. Squared,” ‘I was observing a large huntsman spider (Pandercetes sp.) on a tree when it suddenly leapt and caught a moving subject next to it. Upon closer inspection, I realised that a smaller huntsman spider had caught its own prey and while feeding on it, it had attracted the attention of the larger spider. If you look closely, you can see the pools of venom secreting from its fangs. Cannibalism among spiders is quite common, but finding such beautiful spiders showing this behaviour was a highlight from my trip to Malaysia.’ © Peter Grob | cupoty.com
Two frogs and a toad
Animals Finalist: “Frogs and Toad Mating,” ‘‘As I was walking around my local lake looking for amphibians on a warm spring evening I began to hear the calls of frogs and toads coming from a small area around the roots of an Alder tree at the edge of the water. I watched the mass of amphibians until the light disappeared and noticed two frogs next to the water on the edge of the footpath. When I went to have a better look and take some images, I noticed that this pair had a common toad attempting to join!’ © Nathan Benstead | cupoty.com

There are some decent cheap webcams on the market, but you can go the DIY route and use your phone instead. It takes a little bit of setup, but modern smartphones offer impressive image quality without any extra expenditure.

We all know that built-in webcams look terrible, and that phones take pretty great pictures, so it makes sense to use your phone’s fantastic camera for video calls on your computer. Apple already built this feature into the iPhone, if you have a Mac. Windows users, meanwhile, can use a third party application to turn either an iPhone or an Android phone into a wireless webcam. 

Use Your iPhone as a webcam for you Mac

If you’ve got both an iPhone and a Mac you can use the Continuity Camera feature offered by Apple. All you need is an iPhone running at least iOS 16 and a Mac running macOS Ventura (also known as macOS 13) or later. Both devices need to have both Bluetooth and WiFi turned on and both devices need to be signed into the same Apple ID. 

In any application that uses the video camera, simply select your iPhone as the source. For example, on Zoom, click the arrow beside the video button and then select your iPhone as the camera. It works right away, and you will notice the quality difference.

Use an iPhone or Android phone as a webcam for you Windows or Linux computer

Windows users don’t have an official alternative to Continuity Camera but Droidcam is the next best thing. This application works with both iPhone and Android phones, and allows you to use those phones as a webcam on a Windows or Linux computer. You will need to install the app on your phone and on your Windows machine. Make sure both devices are on the same WiFi network, then open the app on your phone. You will see an IP address; open the app on your computer and type the IP address there. The camera should start working.

Minimize this window then use your video call app of choice. You will see DroidCam listed as an option for both the camera and microphone.

I tested this with Zoom, Google Meet, and Jitsi; it worked well for all of them. The free version only offers standard definition quality. You can upgrade to the pro version to get high definition and a few nice-to-have features including brightness adjustments and auto-focus. The paid upgrade costs $4.99 per year as a subscription or $14.99 as a one-time payment. Alternatively you can watch an ad to get one free hour of HD quality. 

A few things to keep in mind

You can position the phone however you want during the meeting, and even pick it up and move around a little bit. A dedicated phone tripod doesn’t take up much room and provides a solid, adjustable base. There are dedicated stands that sit the camera on top of a monitor, but you don’t necessarily need them. I use a business card stand to hold the phone in place, which works great. A car dash-mount for your phone could also do the trick, in a pinch. 

One more thing to note: using your phone as a camera uses up the battery on your phone. It’s probably a good idea to plug it in, either to your computer or a dedicated charger, while you’re using it.

This article was originally featured on The Conversation.

After 13-year-old Willis Gibson became the first human to beat the original Nintendo version of Tetris, he dedicated his special win to his father, who passed away in December 2023.

The Oklahoma teen beat the game by defeating level after level until he reached the “kill screen”–that is, the moment when the Tetris artificial intelligence taps out in exhaustion, stopping play because its designers never wrote the code to advance further. Before Gibson, the only other player to overcome the game’s AI was another AI.

For any parent who has despaired over their children sinking countless hours into video games, Gibson’s victory over the cruel geometry of Tetris stands as a bracing corrective.

Despite the stereotypes, most gamers are anything but lazy. And they’re anything but mindless.

The world’s top players can sometimes serve as reminders of the best in us, with memorable achievements that range from the heroic to the inscrutably weird.

The perfect run

“Speedrunning” is a popular gaming subculture in which players meticulously optimize routes and exploit glitches to complete, in a matter of minutes, games that normally take hours, from the tightly constrained, run-and-gun action game Cuphead to the sprawling role-playing epic Baldur’s Gate 3.

In top-level competition, speedrunners strive to match the time of what’s referred to as a “TAS,” or “tool-assisted speed run.” To figure out the TAS time, players use game emulators to choreograph a theoretically perfect playthrough, advancing the game one frame at a time to determine the fastest possible time.

Success requires punishing precision, flawless execution and years of training.

The major speedrunning milestones are, like Olympic races, marked by mere fractions of a second. The urge to speedrun likely sprouts from an innate human longing for perfection–and a uniquely 21st century compulsion to best the robots.

A Twitch streamer who goes by the username Niftski is currently the human who has come closest to achieving this androidlike perfection. His 4-minute, 54.631-second world-record speedrun of Super Mario Bros.–achieved in September 2023–is just 0.35 seconds shy of a flawless TAS.

Watching Niftski’s now-famous run is a dissonant experience. Goofy, retro, 8-bit Mario jumps imperturbably over goombas and koopa troopas with the iconic, cheerful “boink” sound of his hop.

Meanwhile, Niftski pants as his anxiety builds, his heart rate–tracked on screen during the livestream–peaking at 188 beats per minute.

When Mario bounces over the final big turtle at the finish line–“boink”–Niftski erupts into screams of shock and repeated cries of “Oh my God!”

He hyperventilates, struggles for oxygen and finally sobs from exhaustion and joy.

The largest world and its longest pig ride

This list couldn’t be complete without an achievement from Minecraft, the revolutionary video game that has become the second-best-selling title in history, with over 300 million copies sold–second only to Tetris’ 520 million units.

Minecraft populates the video game libraries of grade-schoolers and has been used as an educational tool in university classrooms. Even the British Museum has held an exhibition devoted to the game.

Minecraft is known as a sandbox game, which means that gamers can create and explore their own virtual worlds, limited only by their imagination and a few simple tools and resources–like buckets and sand, or, in the case of Minecraft, pickaxes and stone.

So what can you do in the Minecraft playground?

Well, you can ride on a pig. The Guinness Book of World Records marks the farthest distance at 414 miles. Or you can collect sunflowers. The world record for that is 89 in one minute. Or you can dig a tunnel–but you’ll need to make it 100,001 blocks long to edge out the current record.

My personal favorite is a collective, ongoing effort: a sprawling, global collaboration to recreate the world on a 1:1 scale using Minecraft blocks, with blocks counting as one cubic meter.

At their best, sandbox games like Minecraft can bring people closer to the joyful and healthily pointless play of childhood–a restorative escape from the anxious, utility-driven planning that dominates so much of adulthood.

The galaxy’s greatest collaboration

The Halo 3 gaming community participated in a bloodier version of the collective effort of Minecraft players.

The game, which pits humans against an alien alliance known as the Covenant, was released in 2007 to much fanfare.

Whether they were playing the single-player campaign mode or the online multiplayer mode, gamers around the world started seeing themselves as imaginary participants in a global cause to save humanity–in what came to be known as the “Great War.”

They organized round-the-clock campaign shifts, while sharing strategies in nearly 6,000 Halo wiki articles and 21 million online discussion posts.

Halo developer Bungie started tracking total alien deaths by all players, with the 10 billion milestone reached in April 2009.

Game designer Jane McGonigal recalls with awe the community effort that went into that Great War, citing it as a transcendent example of the fundamental human desire to work together and to become a part of something bigger than the self.

Bungie maintained a collective history of the Great War in the form of “personal service records” that memorialized each player’s contributions–medals, battle statistics, campaign maps and more.

The archive beggars comprehension: According to Bungie, its servers handled 1.4 petabytes of data requests by players in one nine-month stretch. McGonigal notes, by way of comparison, that everything ever written by humans in all of recorded history amounts to 50 petabytes of data.

Gamification versus gameful design

If you’re mystified by the behavior of these gamers, you’re not alone.

Over the past decade, researchers across a range of fields have marveled at the dedication of gamers like Gibson and Niftski, who commit themselves without complaint to what some might see as punishing, pointless and physically grueling labor.

How could this level of dedication be applied to more “productive” endeavors, they wondered, like education, taxes or exercise?

From this research, an industry centered on the “gamification” of work, life and learning emerged. It giddily promised to change people’s behaviors through the use of extrinsic motivators borrowed from the gaming community: badges, achievements, community scorekeeping.

The concept caught fire, spreading everywhere from early childhood education to the fast-food industry.

Many game designers have reacted to this trend like Robert Oppenheimer at the close of the eponymous movie – aghast that their beautiful work was used, for instance, to pressure Disneyland Resort laborers to load laundry and press linens at anxiously hectic speeds.

Arguing that the gamification trend misses entirely the magic of gaming, game designers have instead started promoting the concept of “gameful design.” Where gamification focuses on useful outcomes, gameful design focuses on fulfilling experiences.

Gameful design prioritizes intrinsic motivation over extrinsic incentives. It embraces design elements that promote social connection, creativity, a sense of autonomy–and, ultimately, the sheer joy of mastery.

When I think of Niftski’s meltdown after his record speedrun–and Gibson’s, who also began hyperventilating in shock and almost passed out–I think of my own children.

I wish for them such moments of ecstatic, prideful accomplishment in a world that sometimes seems starved of joy.

In an era of climate change, Alaska’s predators fall prey to politics https://www.popsci.com/environment/alaska-predator-control-caribou-wolves-bear-hunt/ Sun, 14 Jan 2024 17:00:00 +0000 https://www.popsci.com/?p=598585

With Alaska's wildlife numbers declining, agencies are blaming—and culling—predators. The true threat is much more complex.

As spring arrived in southwestern Alaska, a handful of people from the state Department of Fish and Game rose early and climbed into small airplanes. Pilots flew through alpine valleys, where ribs of electric green growth emerged from a blanket of snow. Their shadows crisscrossed the lowland tundra, where thousands of caribou had gathered to calve. Seen through the windscreen, the vast plains can look endless; Wood-Tikchik State Park’s 1.6 million acres comprise almost a fifth of all state park land in the United States.

As the crew flew, it watched for the humped shape of brown bears lumbering across the hummocks. When someone spotted one, skinny from its hibernation, the crew called in the location to waiting helicopters carrying shooters armed with 12-gauge shotguns. 

Over the course of 17 days, the team killed 94 brown bears—including several year-old cubs, who stuck close to their mothers, and 11 newer cubs that were still nursing—five black bears and five wolves. That was nearly four times the number of animals the agency planned to cull. Fish and Game says this reduced the area’s bear population by 74 percent, though no baseline studies to determine their numbers were conducted in the area. 

The goal was to help the dwindling number of Mulchatna caribou by reducing the number of predators around their calving grounds. The herd’s population has plummeted, from 200,000 in 1997 to around 12,000 today. But the killings set off a political and scientific storm, with many biologists and advocates saying the operation called into question the core of the agency’s approach to managing wildlife, and may have even violated the state constitution. 

The Board of Game, which has regulatory authority over wildlife, insisted that intensive control of predators in Wood-Tikchik was the best way to support the struggling herd. But the caribou, which provide essential food and cultural resources for many Alaska Native communities, are facing multiple threats: A slew of climate-related impacts have hampered their grazing, wildfires have burned the forage they rely on, warmer winters may have increased disease, and thawing permafrost has disrupted their migrations.

With conditions rapidly changing as the planet warms, wildlife managers nationwide are facing similar biodiversity crises. Rather than do the difficult work of mitigating rising temperatures, state agencies across the country are finding it easier to blame these declines on predation.

“We don’t want to talk about how the tundra is changing, because that’s something we can’t fix,” says Christi Heun, a former research biologist at Alaska Fish and Game.

In Wyoming, where a deadly winter decimated pronghorn and mule deer, the state spent a record $4.2 million killing coyotes and other predators and is considering expanding bear and mountain lion hunts. Wildlife officials in Washington are contemplating killing sea lions and seals to save faltering salmon populations from extinction. In Minnesota, hunters are inaccurately blaming wolves for low deer numbers and calling for authorities to reduce their population. Culls like these are appealing because they are tangible actions—even when evidence suggests the true threat is much more complex. “You’re putting a Band-Aid on the wrong elbow,” says Heun, who now works for the nonprofit Defenders of Wildlife. 

As the climate crisis intensifies, she and others say, wildlife management strategies need to shift too. “All we can do is just kind of cross our fingers and mitigate the best we can,” she adds. For people whose job is to control natural systems, “that’s a hard pill to swallow.”


In January 2022, a flurry of snow fell as the Alaska Board of Game gathered in Wasilla, far from where the Mulchatna caribou pawed through drifts, steam rising from their shaggy backs. Its seven members are appointed by the governor. Though they make important decisions like when hunting seasons open, how long they last, and how many animals hunters can take, they are not required to have a background in biology or natural resources. They also do not have to possess any expertise in the matters they decide. Board members, who did not respond to requests for comment, tend to reflect the politics of the administration in office; currently, under Republican Governor Mike Dunleavy, they are sport hunters, trappers, and guides. 

That day, the agenda included a proposal to expand a wolf control program from Wood-Tikchik onto the Togiak National Wildlife Refuge—though that would require federal approval from the U.S. Fish and Wildlife Service; the government ultimately rejected the proposal.

The conversation began with two Fish and Game biologists summarizing their research for the board on the herd. Nick Demma explained that, like most ungulates, on average half of Mulchatna’s calves survive. In a study he conducted, many died within two weeks of birth; he mentioned as an aside that their primary predators are brown bears. “But I want to stress that this basic cause of death and mortality rate information is of little use,” he quickly added. Predator and prey dynamics are complex: The calves may have died anyway from injury or disease, and their removal may reduce competition for food and resources, improving the herd’s overall health. 

When Demma tried to analyze the existing wolf control program, he found he didn’t have the data he needed to see if removing the canines helped calves survive. In fact, from 2010 to 2021, when Fish and Game was actively shooting wolves, fewer caribou survived. So the researchers turned their attention to other challenges the herd might be facing. 

His colleague, Renae Sattler, explained that preliminary data from a three-year study suggested there could be a problem with forage quality or quantity, especially in the summer. This could lower pregnancy rates or increase disease and calf mortality. In the 1990s, the herd had swelled as part of a natural boom-and-bust cycle, leading to overgrazing. The slow-growing lichen the animals rely on takes 20 to 50 years to recover. Compounding that, climate change is altering the tundra ecosystem the animals rely upon. She also found that today, 37 percent of the sampled animals had, or were recently exposed to, brucellosis, which can cause abortions, stillbirths, and injuries. Biologists consider such high levels of disease an outbreak and cause for concern.

Sattler also noted that half of the animals that died in the study’s first year were killed by hunters taking them out of season—meaning the predators killing the most adult caribou were people. For all these reasons, the biologists suggested that the Board of Game reconsider the wolf control program.

Commissioner Doug Vincent-Lang, who oversees the agency, immediately questioned their conclusions, and their recommendation. Killing predators, he said during the meeting, “seems like one of the only things that’s within our direct control.” In other words, it was better than doing nothing. 

Demma seemed taken aback, and chose his words carefully. “I guess what we are kind of trying to present there is just the information,” he told the board. “It’s—you know—wolves aren’t an important factor right now.” The meeting broke for lunch. When it resumed, the board unanimously voted to continue the wolf program through 2028, and, even more surprisingly, to add brown and black bears over a larger area. The public and Fish and Game biologists didn’t have the typical opportunity to comment on this expansion of predator control.

When he heard what happened, “I just was stunned. I was shocked,” says Joel Bennett, a lawyer and a former member of the Board of Game for 13 years. A hunter himself, Bennett served on the board under four governors and recalls his colleagues having a greater diversity of backgrounds and perspectives. Their votes were always split, even on less contentious issues. The unanimous vote “in itself indicates it’s a stacked deck,” he says. That’s a problem, because “the system only works fairly if there is true representation.”

In August, Bennett and the Alaska Wildlife Alliance filed a lawsuit claiming the agency approved the operation without the necessary “reasoned decision-making,” and without regard for the state’s due process requirements. Bennett also was troubled that the state has tried to keep information about the cull private, including where the bears were killed. He suspects that, to have slain so many animals in just 17 days, the flights might have veered beyond the targeted area. He also wonders if any animals were left wounded. “Why are they hiding so many of the details?” he asked. A public records request reveals that although the board expected the removal of fewer than 20 bears, almost five times that many were culled without any additional consideration. 

Alaska’s wildlife is officially a public resource. Provisions in the state constitution mandate game managers provide for “sustained yields,” including for big game animals like bears. That sometimes clashes with the Dunleavy administration’s focus on predator control. In 2020, for example, the board authorized a no-limit wolf trapping season on the Alexander Archipelago, a patchwork of remote islands in southeast Alaska. It resulted in the deaths of all but five of the genetically distinct canines. The Alaska Wildlife Alliance sued, a case Bennett is now arguing before the state Supreme Court. “That was a gross violation of ‘sustained yield’ in anyone’s definition,” he says, adding that even today, there is no limit on trapping wolves there.

Once, shooting bison from moving trains and leaving them to rot was widely accepted. Attitudes have evolved, as have understandings about predators’ importance—recent research suggests their stabilizing presence may play a crucial role in mitigating some of the effects of climate change. Other studies show predators may help prey adapt more quickly to shifting conditions. But Bennett worries that, just as Alaska’s wildlife faces new pressures in a warming world, management priorities are reverting to earlier stances on how to treat animals. “I’ve certainly done my time in the so-called ‘wolf wars,’” Bennett says, “but we’re entering a new era here with other predators.”


Even as legal challenges to the board’s decisions move forward, scientific debate over the effectiveness of predator control has flourished. Part of the problem is that game management decisions are rarely studied in the way scientists would design an experiment. “You’ve got a wild system, with free-ranging animals, and weather, and other factors that are constantly changing,” says Tom Paragi, a wildlife biologist for the state Department of Fish and Game. “It’s just not amenable to the classic research design.” Even getting baseline data can take years, and remote areas like Wood-Tikchik, which is accessible only by air or boat, are challenging and expensive places to work. 

Paragi has for more than a decade monitored the state’s intensive wildlife management programs and believes predator control can be effective. Looking at data collected since 2003, he notes that when Alaska culled wolves in four areas in a bid to bolster moose, caribou, and deer populations, their numbers increased. They also remained low in those areas where wolves were left alone. (His examination of this data has not yet been published or subject to peer review.) Elsewhere in the state, removing 96 percent of black bears in 2003 and 2004, reducing hunting, and killing wolves boosted the number of moose. Heavy snowfall during the next two winters killed many of the calves, and most of the bears returned within six years, but Paragi still considers the efforts a success. By 2009, the moose population had almost doubled.

He’s also not convinced that Demma and Sattler were right when they told board members that predation doesn’t appear to be the most pressing issue for the Mulchatna caribou. He says record salmon runs have likely brought more bears near the park and the calving grounds, and warmer temperatures have fostered the growth of vegetation that provides places to hide as they stalk caribou. As to the suggestion that the herd is suffering from inadequate food supplies, he notes that their birth rate has been high since 2009. That’s often a strong indicator of good nutrition. 

But Sattler says, “It isn’t that cut-and-dried.” A female caribou’s body condition, she explains, exists on a spectrum and affects her survival, the size and strength of any calves, and how long she can nurse or how quickly she gets pregnant again. “The impact of nutrition is wide-reaching and complex, and it isn’t captured in pregnancy rates alone.” Understanding how nutrition, brucellosis, and other factors are impacting the herd is complicated, she says. 

There are a lot of interacting factors at play on the tundra—and among those trying to determine how best to help the herd. “Part of the frustration on all sides of this is that people have different value systems related to managing wild systems,” Paragi says. To him, last spring’s bear kill wasn’t truly a question of science. “We can present the data, but what you do with the data is ultimately a political decision,” he says. 

Sterling Miller, a retired Fish and Game research biologist and former president of the International Association for Bear Research and Management, acknowledges that crafting regulations is left to the politically appointed Board of Game. But Miller says the agency tends to dismiss criticism of its predator control, when there are valid scientific questions about its effectiveness. In 2022, Miller and his colleagues published an analysis, using Fish and Game harvest data, showing that 40 years of killing predators in an area of south-central Alaska didn’t result in more harvests of moose. “Fish and Game has never pointed out any factual or analytical errors in the analyses that I’ve been involved with,” he says. “Instead, they try to undercut our work by saying it’s based on values.”  

Miller also was involved in what remains one of the agency’s best examples of predator relocations. In 1979, he and another biologist moved 47 brown bears out of a region in south-central Alaska, which resulted in a “significant” increase in the survival of moose calves the next fall. But Miller says Fish and Game often misquotes that work. In reality, due to a lack of funding, Miller didn’t study the young animals long enough to see if they actually reached adulthood. Similarly, Fish and Game conducted an aerial survey this fall of the Mulchatna herd, finding more calves survived after the bear cullings. But Miller and other biologists say that’s not the best metric to measure the operation’s success: These calves may still perish during their first winter. 

The Alaskan government is the only one in the world whose goal is to reduce the number of brown bears, Miller says, despite the absence of baseline studies on how many bears are in this part of the state. It irks him that the state continues to use his research as justification for allowing predator measures like bear baiting. In most parts of Alaska, Miller says, “the liberalization of bear hunting regulations has just been so extreme.” 

While last year’s bear killings were particularly egregious, similar cullings have gone largely unnoticed. State data shows over 1,000 wolves and 3,500 brown and black bears have been killed since 2008 alone. In 2016, for example, the federal government shared radio tag information with the state, which used it to kill wolves when they left the safety of the Yukon-Charley Rivers National Preserve—destroying so many packs that it ended a 20-year study on predator-prey relationships. “There weren’t enough survivors to maintain a self-sustaining population,” recounted an investigation by the nonprofit Public Employees for Environmental Responsibility. The nearby caribou herd still failed to recover.

Multiple employees for Fish and Game, who didn’t want to be named amid fear of repercussions, told Grist that the agency was ignoring basic scientific principles, and that political appointees to the Board were not equipped to judge the effectiveness of these programs.

Even these criticisms of the agency’s science have been subject to politics: This summer, a committee of the American Society of Mammalogists drafted a resolution speaking out about Alaska’s predator control—only for it to be leaked to Fish and Game, which put up enough fuss that it was dropped. Link Olson, the curator of mammals at the University of Alaska Museum of the North, was one of many who supported the group taking a position on the issue. Olson says that even as someone who “actively collect[s] mammal specimens for science,” he is deeply concerned with Alaska’s approach to managing predators.

A month later, 34 retired wildlife managers and biologists wrote an open letter criticizing the bear cull and calling the agency’s management goals for the Mulchatna herd “unrealistic.” Meanwhile, neither Demma nor Sattler, the biologists who cautioned the board, are still studying the herd; Demma now works in a different area of the agency, and Sattler has left the state and taken a new job, for what she says are a variety of reasons.


Every fall, millions of people follow a live-streamed view of the biggest bears in Katmai National Park, which sits southeast of Wood-Tikchik. The animals jockey for fish before their hibernation, in an annual bulking up that the National Park Service has turned into a playful competition, giving the bears nicknames like “Chunk,” and, for a particularly large behemoth, 747. 

Though marked on maps, animals like 747 don’t know where the comparative safety of the national park ends and where state management begins. This can mean the difference between life and death, as Alaskan and federal agencies have taken very different approaches to predator control: The National Park Service generally prohibits it. This has sparked a years-long federalism battle. Back in 2015, for example, the Board of Game passed a rule allowing brown bear baiting in the Kenai National Wildlife Refuge, leading the Fish and Wildlife Service to ban it in 2016. The state sued, and in 2020 the Trump administration proposed forcing national wildlife refuges to adopt Alaska’s hunting regulations. Similarly, the National Park Service challenged whether it had to allow practices like using spotlights to blind and shoot hibernating bears in their dens in national park preserves. In 2022, the 9th U.S. Circuit Court of Appeals ruled that federal agencies have ultimate authority over state laws in refuges; last year, the Supreme Court declined to hear the case.

How these agencies interact with local communities is markedly different, too. Both Alaska Fish and Game and the U.S. Fish and Wildlife Service have regional advisory groups where residents can weigh in on game regulations, but Alissa Nadine Rogers, a resident of the Yukon- Kuskokwim Delta who sits on each, says that, unlike the federal government, it feels like “the state of Alaska does not recognize subsistence users as a priority.” On paper, the state prioritizes subsistence use, but under its constitution, Alaska can’t distinguish between residents, whereas the federal government can put the needs of local and traditional users first. This has frequently led to separate and overlapping state and federal regulations on public lands in Alaska. 

Many people in the region rely on wildlife for a substantial part of their diet. Since the area isn’t connected by roads, groceries must be barged or flown in, making them expensive—a gallon of milk can cost almost $20. In addition to being an important food source, caribou are a traditional part of her Yupik culture, Rogers explains, used for tools and regalia. It’s a real burden for local communities to be told they can’t hunt caribou, which has driven poaching. As state and federal regulations have increased restrictions on hunting, she says residents have difficulty obtaining enough protein to sustain themselves through the winter. “If people don’t understand how it is to live out here, what true perspective do they have?” she asks. “Subsistence users are the ones who bear the burden when it comes to management. And a lot of the time, folks aren’t feeling that their voices are being heard or adequately represented.”

Yet Rogers says state and federal systems can provide an important balance to each other, and she approves of Fish and Game’s predator control efforts. As the former director of natural resources for the Orutsararmiut Native Council, she helped the council write a resolution, later passed by the statewide Alaska Federation of Natives, supporting last spring’s bear and wolf cull. She thinks officials should focus more on climate change but believes culling remains a useful tool. “It gives a vital chance for the [caribou] population and immediately supports growth and recovery,” Rogers says. She also asked Fish and Game to institute a five-year moratorium on all hunting of the herd. “If we go any lower, then we’re pretty much gonna be facing extinction.”

Who gets to make choices about the state’s fish and wildlife resources is a point of increasing tension this year, as a lawsuit unfolds between the state and federal government over who should manage salmon fisheries on the Kuskokwim River, to the west of the Togiak refuge. All five of its salmon returns have faltered for over a decade—making game like caribou even more critical for local communities. (In sharp contrast, to the east of the river, Bristol Bay has seen record recent returns, showing how variable climate impacts can be.) The Alaska Native Federation and the federal government say fishing should be limited to subsistence users, while the state has opened fishing to all state residents.

To ensure Alaska Native communities have a voice in such critical decisions, the Federation called for tribally designated seats on the Board of Game this fall. “We need to have a balanced Board of Game that represents all Alaskans,” says former Governor Tony Knowles. He, too, recommends passing a law to designate seats on the board for different types of wildlife stakeholders, including Alaska Native and rural residents, conservationists, biologists, recreational users, and others. Knowles also proposes an inquiry into Fish and Game’s bear killings, including recommendations on how to better involve the public in these decisions. “We deserve to know how this all happened so it won’t happen again.”

It’s clear to many that business as usual isn’t working. “I have no idea how the state comes up with their management strategy,” says Brice Eningowuk, the tribal administrator for the council of the Traditional Village of Togiak, an Alaska Native village on the outskirts of the Togiak refuge. He says Fish and Game didn’t tell his community about the bear cull, and he expressed skepticism that primarily killing bears would work. “Bears will eat caribou, but that’s not their primary food source,” he says.

Part of the solution is setting more realistic wildlife goals, according to Pat Walsh, whose career as a U.S. Fish and Wildlife biologist involved supervising the caribou program in the Togiak refuge. Recently retired, he says the current goal for the Mulchatna herd size was set 15 years ago, when the population was at 30,000, and is no longer realistic. Reducing that goal could allow targeted subsistence use—which might help ease some of the poaching. Though Fish and Game has killed wolves around the Mulchatna herd for 12 years, he points out the caribou population has steadily dropped. “We recommended the board reassess the ecological situation,” he says, and develop goals “based on the current conditions, not something that occurred in the past.” 

Today’s landscape already looks quite different. Alaska has warmed twice as quickly as the global average, faster than any other state. When Rogers was in high school, she tested the permafrost near her house as an experiment. As a freshman, she only had to jam the spade in the ground before she hit ice. By the time she was a senior, it thawed to a depth of 23 inches—and in one location, to 4 feet. Summers have been cold and wet, and winters have brought crippling ice storms, rather than snow. Berry seasons have failed, and the normally firm and springy tundra has “disintegrated into mush,” Rogers says.

Feeling the very ground change beneath her feet highlights how little sway she has over these shifts. “How are you gonna yell at the clouds? ‘Hey, quit raining. Hey, you, quit snowing’?” Rogers asked. “There’s no way you can change something that is completely out of your control. We can only adapt.”

Yet despite how quickly these ecosystems are shifting, the Department of Fish and Game has no climate scientists. In the meantime, the agency is authorized to continue killing bears on the Mulchatna calving grounds every year until 2028. (The board plans to hear an annual report on the state’s intensive management later this month.) As Walsh summarizes wryly, “It’s difficult to address habitat problems. It’s difficult to address disease problems. It’s easy to say, ’Well, let’s go shoot.’” 

Management decisions can feel stark in the face of nature’s complexity. The tundra is quite literally made from relationships. The lichen the caribou feed on is a symbiotic partnership between two organisms. Fungus provides its intricately branching structure, absorbing water and minerals from the air, while algae produces its energy, bringing together sunlight and soil, inseparable from the habitat they form. These connections sustain the life that blooms and eats and dies under a curving sweep of sky. It’s a system, in the truest and most obvious sense — one that includes the humans deciding what a population can recover from, and what a society can tolerate. 

As another season of snow settles in, the caribou cross the landscape in great, meandering lines. There are thousands of years of migrations behind them and an uncertain future ahead. Like so much in nature, it’s hard to draw a clear threshold. “Everything is going to change,” Rogers says.

Astrobotic also has gathered data from the payloads that were designed to communicate with the lander. “All 10 payloads requiring power have received it, while the remaining 10 payloads aboard the spacecraft are passive,” Astrobotic wrote in a January 11 update. “These payloads have now been able to prove operational capability in space and payload teams are analyzing the impact of this development now.”

What went wrong?

About seven hours after launch, Peregrine was unable to shift its solar panels towards the sun so that its batteries could charge. While the engineering team was able to turn the panels, more problems developed. 

Astrobotic believed that the root of the problem was a failure in the vehicle’s propulsion system that was causing a critical loss of propellant. The company shared the first image of the lander in space, with its outer insulation appearing very crinkled.

By Monday evening, Astrobotic announced that this fuel leak was causing the thrusters in the spacecraft’s attitude control system to “operate well beyond their expected service life cycles to keep the lander from an uncontrollable tumble.” The mission’s priority also became maximizing the data and scientific information that Peregrine could capture and send back to Earth. 

On Tuesday January 9 Astrobotic said that the leak meant that “there is, unfortunately, no chance of a soft landing on the moon. By January 10, Peregrine was roughly 192,000 miles from Earth. The spacecraft was “stable and fully charged” and gathering “valuable data.” They estimated that it will likely shut down at around sometime on Friday January 12.

What will happen to Peregrine?

Peregrine will join the estimated 29,000 pieces of space debris larger than 10 centimeters (3.9 inches). The spacecraft will also be a floating gravesite. Its payload contained DNA samples and portions of cremated remains of three former United States presidents, Star Trek creator Gene Roddenberry, and several members of the original cast of the groundbreaking sci-fi series. 

What is next for public-private lunar exploration?

With this mission, Astrobotic hoped to become the first private business to successfully land on the moon. This is a feat only four countries–Russia, China, India, and the United States–have accomplished. 

A second lander from Houston-based Intuitive Machines is scheduled to launch in February. NASA has given both of these companies millions of dollars to construct and fly their own lunar landers, so that the privately owned landers can explore landing sites before astronauts arrive and deliver critical technology and experiments. Astrobotic’s contract with NASA for the Peregrine lander was $108 million with more to come

This week, NASA leadership announced that it is delaying future missions to the moon, citing safety issues and delays in developing lunar landers and spacesuits. Originally scheduled to launch in November of this year, the Artemis II mission that will send four astronauts around the moon has been postponed to September 2025. Meanwhile, the moon-landing mission Artemis III will now aim for September 2026 instead of late 2025. The Artemis IV mission remains on track for September 2028.

Usually, fossilized animal remains result from bits of bone or impressions of a creature long-passed. But sometimes a specific place has just the right conditions to preserve even more. From Richards Spur, a long filled-in cave network and active quarry in southern Oklahoma, a group of paleontologists say they’ve identified and described the oldest fossilized reptile skin ever found. The soft tissue fossil is a rare find–enabled through a series of chance events. It offers a glimpse into a distant evolutionary past that pre-dates both mammals and the oldest dinosaurs.

The skin sample, about the size of a fingernail and literally paper thin, is described in a study published on January 10 in the journal Current Biology, along with other fossil findings. The ancient, reptilian skin flake is an estimated 286-289 million years old. That’s at least 21 million years older than the next oldest example and more than 130 million years older than the vast majority of comparable samples, which come from mummified dinosaurs that lived in the late Jurassic, says lead study author Ethan Mooney, a biology master’s student at the University of Toronto studying paleontology. 

The fossils’ estimated age is based on the site where they were found. Once, Richards Spur was an open limestone cave, but between 286 and 289 million years ago, it filled in with clay and mud deposits, according to Mooney and Maho. During that in-filling process, the cave stopped forming, so the youngest stalagmite rings present in the cave represent the approximate age of the sediments and the fossils they contain, according to previous research using Uranium-Lead radioisotope dating.

Roger Benson, a paleontologist and curator at the American Museum of Natural History who was not involved in the study, agrees these methods and assumptions are sound. “All the evidence, especially what sorts of fossil groups are present, is consistent with an early Permian age (around 300 to 273 million years ago),” he wrote in an email. 

In addition to the fossilized piece of “skin proper,” the researchers also documented multiple preserved impressions of skin– a much more common type of fossil to find. But unlike with the impressions, which are essentially the outline of an animal pressed into stone, the researchers were able to assess the cross section of their most notable fossil and identify layers and detail that would’ve otherwise been unknowable. 

“At first we thought they were broken pieces of bone,” says Tea Maho, a study co-author and a pHD student at the University of Toronto, of all the epidermal fossils. The skin, she says, “could have just been so easily disregarded until we looked under a microscope.” Then it became clear that they were seeing preserved soft tissue, an exceptionally rare thing among samples that old. 

Usually, soft tissue breaks down quickly before it can fossilize. But Richards Spur is a hotbed of paleontological discovery. The study suggests that oxygen-poor sediments and the presence of oil seeps in the cave system helped to preserve the prehistoric animals and carcasses  that happened to fall in. In this environment, the skin was mummified–the technical term in paleontology for when organic matter dries out before decaying. Because the site is also an actively mined quarry, new layers of fossils are constantly being uncovered.

“The sheer chance for a soft tissue structure to be preserved, to survive until now–through the mining process–to have been found…and then described by us is quite an incredible story,” Mooney says. Especially given how fragile the preserved epidermis is. “If you were to have pressed it a little too hard, it would have just cracked,” says Maho. Thankfully, for our understanding of vertebrate history, the scientists were careful enough to keep the skin sample from becoming dust. 

Though they can’t say for certain what animal the skin specimen was from, Maho and Mooney have an idea. Captorhinus aguti was a lizard-like animal known to have been common in the region during the Permian Period. It had four legs, a tail, was about 10 inches long, and had an omnivorous diet–eating insects, small vertebrates, and occasionally plants. Fossilized skeletal remains of C. aguti have been found at the same site, and aspects of the skin sample are similar to features of those larger fossils. 

On top of being the oldest reptile skin ever discovered, Mooney notes the newly described specimen is also the oldest amniote skin ever found. Amniotes are the subcategory of animals that encompasses reptiles, birds, and mammals, and the finding offers insight into a key moment in animal biology. “It comes from a pivotal time in the evolution of life as we know it. It represents the first chapter of higher vertebrate evolution,” from fish and amphibians to creatures not reliant on aquatic habitats to survive or breed. Skin is the body’s largest organ and plays a major role in moisture regulation. Paleontologists have long assumed that good skin was a big deal for early terrestrial animals, now there’s additional fossil evidence for that view, he adds. 

Incredibly, the ~289 million-year-old specimen closely resembles present-day crocodile skin, according to the study. Both living crocodiles and the ancient bit of preserved epidermis have a pebble-like texture and a non-overlapping scale pattern. This similarity, Mooney says, is further proof of skin’s outsized role in adapting to life on land. “The fact that we have an example from one of these earliest reptiles and it’s quite consistent with what we see in modern reptiles underscores how important that structure was and how successful it was in doing its job.” 

Nearly 300 million years ago, “life would have looked very different,” Mooney says. But reptile skin might not have.

This article was originally featured on The Conversation.

An avalanche swept up skiers at Lake Tahoe’s largest ski resort on Jan. 10, 2024, as a 150-foot-wide sheet of snow slid down a mountain slope into a pile 10 feet deep. One person died in the avalanche and three others were rescued, according to the Placer County Sheriff’s Office in Auburn, California. The slide happened in steep terrain near the KT-22 chairlift, which had just opened for the season that morning.

Avalanche deaths are rare inbounds at ski resorts like Palisades Tahoe, but the risk rises in the backcountry. Nathalie Vriend, a skier and a physicist at the University of Colorado Boulder who studies avalanches, explains what happens in the snowpack when an avalanche begins.

What causes avalanches?

The behavior of an avalanche depends on the structure of the snowpack, but that’s only one ingredient. An avalanche requires all the wrong conditions at the wrong time.

The angle of the mountain slope is important. Slopes between 25 and 40 degrees run the greatest risk of avalanches. Those are also ideal for skiing, of course. If the slope is less than 25 degrees, there might be little slips, but the snow won’t pick up speed. If it’s over 40 degrees, the snow typically cannot accumulate, clearing away the avalanche risk.

Avalanche awareness for backcountry skiers.

Then there needs to be a trigger. A snowpack may be seemingly stable until a snowmobile or skier disturbs it enough that the snow starts to move. Strong winds or rock falls may also cause an avalanche. Blowing snow can create wind loading and build up into cornices, creating an overhang that can eventually fall and trigger an avalanche below.

What happens inside the snowpack during an avalanche?

Mountain snowpack isn’t uniform. Because it builds up over time, it is a snapshot of recent weather conditions and has both stable and weak layers.

When snow falls, it’s a fluffy crystal structure. But when the temperature rises and the snow starts to melt and then refreezes, it turns more granular.

That granular, icier snow is a weak layer. When a new snowfall dumps on top of it, the grains in the weak layer can shear, creating a surface for an avalanche to slide on. The weight of new snowpack can cause the entire face of a mountain to fall away almost instantaneously. As the avalanche picks up speed, more snow and debris are incorporated in the avalanche and it can become really big and violent.

In my lab at the University of Colorado at Boulder, I study small-scale laboratory avalanches. We use a technique called photoelasticity and create thin avalanches to reveal what’s going on inside the avalanche. We track photoelastic particles with a high-speed camera and can observe that particles bounce and collide really fast, within 1/1,000th of a second.

In a real avalanche, those violent collisions create a lot of heat through friction, which causes more melting. As the avalanche comes to a rest, this liquid can quickly refreeze again, locking the snowpack in place like concrete. People say “swim to the surface” in an avalanche, but you may not know whether the surface is up or down. If the avalanche is still moving and the granules haven’t frozen solid again, you might be able to move slightly, but it is really hard.

What can skiers do if they’re in an avalanche?

I’ve done fieldwork on real snow avalanches triggered intentionally in Switzerland. We were in a bunker in a valley, and they dropped explosives at the top of the mountain. Using radar, we could look inside the avalanche as it came toward us. It was easily going more than 110 miles per hour (50 meters per second).

Even if the avalanche is small, you can’t outski or outrun it easily. The big danger is when the snow is deep–you could be buried under several feet of snow. Basically, as the avalanche slows down, new snow keeps piling on top of you. People report this as being trapped in concrete without an ability to even move a limb. It must be a very frightening experience.

Backcountry skiers carry tools that can increase their chances of survival. Your best bet, though, is your peers – particularly in the backcountry, where emergency crews will take hours to arrive.

There are a few things you can do. First, carry a transceiver, which transmits a signal identifying your location. When you are caught in an avalanche, you are transmitting a signal. Your friends can switch their transceivers to the “receiving” mode and try to locate your beacon. It’s also important to have an avalanche probe and a shovel in the backcountry for when your friends do locate your position: The snow is like concrete, and it will be hard to extract you.

Avalanche air bags can also help–James Bond used an elaborate concept of one in “The World Is Not Enough.” You pull a toggle on your back, and the air bag turns you into a bigger particle. Bigger particles tend to stay at the surface, making you easier to locate.

How is avalanche risk changing as winter temperatures rise?

It’s an important question, and it’s not as simple as warming temperatures mean less snow, so fewer avalanches. Instead, if mountains have more variation in temperatures, they may have more melting and refreezing phases during the winter, creating weaker snowpacks compared with historical records.

The historical conditions that communities have grown up around can change. In 2017, there was a big avalanche in Italy that took out an entire hotel. It was in an area where people didn’t expect an avalanche, based on historical data.

There are computer models that can calculate where avalanches are likely to occur. But when temperatures, snowfall and precipitation patterns change, you may not be able to truly understand cause and effect on natural hazards like snow avalanches.

A budget-friendly option with plenty of magnification and light-gathering capabilities.

Telescopes for deep space allow you to gaze at the wonders of our universe in a way that wouldn’t be possible with other telescopes. These powerful devices use larger apertures to gather loads of light, illuminating what would be too dim to see otherwise. Many even offer motorized mounts to move to the celestial objects you want to admire automatically. Whether you are a new astronomer or a seasoned pro, the best telescopes for deep space will broaden your horizons.

How we chose the best telescopes for deep space

Telescopes for deep space have more specific requirements than general telescopes. Because of this, we selected powerful scopes with large apertures and plenty of magnification. Beyond those two factors, we also looked for options with and without motorized mounts. Finally, we assessed the quality of the optics, build quality, mount type, and any extra features. We selected based on a mix of hands-on telescope experience, expert insight, editorial reviews, and user feedback. 

The best telescopes for deep space: Reviews & Recommendations

If you want to see beyond planets and our moon, you’ll need a telescope for deep space. These powerful scopes will open up the ability to gaze at deep sky objects (DSOs), such as star clusters, nebulas, and galaxies, providing new opportunities for epic stargazing sessions.

Best overall: Celestron NexStar 8SE

  • Eyepiece: 25mm (81x) Plössl
  • Weight: 24 pounds
  • Dimensions: 42.01 x 23.66 x 12.99 inches

Pros

  • Computerized mount makes tracking easy
  • Very sharp across entire field of view
  • Large aperture
  • Portable

Cons

  • Slewing results in some lag

Our best overall pick comes from one of the most trusted telescope manufacturers. The Celestron NexStar 8SE is a relatively portable Schmidt-Cassegrain scope. It weighs 24 pounds but is quite compact, so you can bring it to dark-sky locations if needed. 

This telescope for deep space offers a minimum useful magnification of 29x and a maximum useful magnification of 480x, making it a versatile tool for viewing a wide range of celestial objects, including planets. Plus, the eight-inch aperture captures plenty of light for DSOs. Provided you don’t have much light pollution, you’ll be able to see nebulas, galaxies, and more clearly.  

This type of telescope requires collimation, but Celestron’s SkyAlign makes it quick and easy, even for beginners. Another plus for beginners and pros alike is the included alt-azimuth mount, a fully automated Go-To mount. You can select from a database of 40,000 objects, and the telescope will automatically find it and track it across the sky for you. It also comes with a 25mm eyepiece, StarPointer finderscope, visual back, and mirror star diagonal. The NexStar 8SE is pricey, but you get a lot of value for that price that is hard to beat.

Best smart: Unistellar Equinox 2

Unistellar

SEE IT

Specs

  • Optical design: Newtonian reflector
  • Mount: Computerized alt-azimuth  
  • Aperture: 114mm
  • Focal length: 450mm

  • Expensive
  • Lack of an eyepiece isn’t for everyone

For those who want to gaze into the heavens from the comfort of their couch, the Unistellar Equinox 2 is the way to go. This smart telescope is unique in that it doesn’t feature an eyepiece. Instead, you pair the scope with the easy-to-use Unistellar app and view from there. This won’t be everyone’s cup of tea, but it makes deep space observation easier for groups and kids. It also came in handy for those mosquito-ridden Florida nights, as my husband and I could stargaze from inside.

The Equinox 2 features a sturdy base with a computerized alt-az mount. After an easy alignment process, you can search a database of 5,000 objects, including DSOs. Then, the telescope will automatically find and track them across the night sky. Or, you can use the in-app joystick to browse on your own. 

One of the best features of the Equinox 2 is its Deep Dark Technology, which filters out light pollution. This opens up stargazing even to those living in cities. Though I don’t live in a large city, there is a lot of light pollution, and it was remarkable what I was able to see with this setting turned on. Should you want to travel to dark sky locations, the telescope is relatively compact and portable, and you can even purchase a bundle with a backpack for easier transportation.

  • Optical design: Schmidt-Cassegrain
  • Mount: Computerized equatorial mount 
  • Aperture: 203mm (8 inches)
  • Focal length: 2032mm
  • Eyepiece: 12mm (150x) and 40mm (38x)
  • Weight: 61 pounds (full kit)
  • Dimensions: ‎9.1 x 9.1 x 9.1 inches

Pros

  • Very compact
  • Accurate Go-To mount
  • Extremely high-quality optics
  • Excellent for both astrophotography and observation

Cons

  • Mount isn’t sturdy enough for long-exposure astrophotography
  • Expensive

Our splurge pick is also one of the best telescopes for astrophotography. It features high-quality optics that fully correct for coma and field curvature, resulting in a truly flat field. Plus, the StarBright XLT coatings provide better light transmission for bright, sharp images. 

The included equatorial mount makes tracking objects easy, so you can make long observations or take long-exposure photos. It is computerized with Go-To functionality, making it easy to find and automatically track objects of interest. The mount even features ports for hand control, an autoguider, and two AUX ports for optional accessories. All those ports make it an ideal option for seasoned pros or for beginners who want something to grow into. 

Adding to the versatility of this scop is the ability to use three different f-stop configurations. You can attach a camera to the scope for f/10 or attach the eight-inch EdgeHD focal reducer to shoot at f/7. Finally, the EdgeHD is Fastar/Hyperstar compatible, making it possible to shoot at f/2. It is also quite compact, albeit fairly heavy, making it feasible to travel with. This is an expensive telescope for deep space, but you won’t be disappointed if you want something to last a long time or are looking for extremely high-quality optics.

Best compact: Vaonis Vespera

Vaonis

SEE IT

Specs

  • Optical design: Apochromatic (APO) quadruplet refractor
  • Mount: Computerized alt-azimuth  
  • Aperture: 50mm (2 inches)
  • Focal length: 200mm
  • Eyepiece: Not applicable
  • Weight: 11 pounds
  • Dimensions: 15 x 8 x 3.5 inches

Pros

  • Very compact and portable
  • Helps remove light pollution
  • Sleek, futuristic design
  • Ideal for group observations

Cons

  • Images aren’t very high-quality

The Vaonis Vespera is one of the best options If you love to travel and want a telescope for deep space to take along. Weighing only 11 pounds and measuring 15 by 8 by 3.5 inches,  the Vespera is very compact for what it provides. It also features a futuristic design, which will look nice sitting in your home. 

Like the Unistellar telescope, this option doesn’t offer an eyepiece. It can pair with up to five smartphones or tablets via the Singularity app, making it a fun way to stargaze with friends. Also like the Unistellar, it can filter out light pollution so that you can view DSOs even in cities. The telescope and app are both easy to use, so you’ll have no issues if you are a complete novice. 

The Vespera uses a Sony IMX462 image sensor to produce images. Unfortunately, this isn’t a great option if you want high-quality images of celestial objects. It only offers a resolution of 1920 by 1080 pixels, and users report that images are a little on the soft side. But it uses your phone’s GPS to calibrate yourself and automatically tracks objects, taking the work out of stargazing.

Best budget: Sky-Watcher 8″ Flextube 200P

Sky-Watcher

SEE IT

Specs

  • Optical design: Newtonian reflector
  • Mount: Dobsonian
  • Aperture: 203mm (8 inches)
  • Focal length: 1200mm
  • Eyepiece: 10mm (120x) and 25mm (48x)
  • Weight: 52 pounds (full kit)
  • Dimensions: Base: 29.5 x 20 inches

Pros

  • Included mount is very sturdy
  • Very large aperture for the price
  • Comes with two eyepieces and an eyepiece tray
  • Smooth movements for manual tracking

Cons

  • Not motorized Go-To functionality

Telescopes for deep space are not cheap; there’s no getting around it. But the Sky-Watcher 8” Flextube 200P offers a much more budget-friendly option for deep sky observation. Coming in well below $1,000 when writing, this device provides a large eight-inch aperture for plenty of light gathering. 

The Flextube 200P comes with two eyepieces, offering more versatility. It also includes an eyepiece tray to keep your accessories organized. The 1200mm focal length offers plenty of reach for deep space viewing, with a maximum useful magnification of 400x. The high-quality mount allows for smooth movements as you scan the sky.

This is not a lightweight device at 52 pounds (the base and scope combined). But it is relatively compact so that it will fit well in smaller spaces. Should you need to transport the scope, it comes apart in two pieces to make it easier. The Flextube 200P also doesn’t feature a motorized mount, meaning it requires manual input for finding and tracking objects. Purists will appreciate that, but it may take some getting used to for novices. It comes with a 50mm finder, though, which makes it easier to find what you are after.

What to consider when buying the best telescopes for deep space

Telescopes for deep space have some specific requirements beyond most scopes. Add to that all the highly technical jargon that goes along with telescopes, and it can be extremely confusing what to actually pay attention to when shopping. Below are some key features you’ll need to consider when choosing your new telescope to look out at the cosmos’ wonders. 

Aperture

The aperture is the most important aspect of a telescope for deep space (yes, this is even more important than magnification). A telescope’s aperture controls how much light is let in. It is measured in millimeters or inches. If you want to check out deep-space objects, you’ll need a telescope with a large aperture to gather as much light as possible. Broadly speaking, your best bet is to choose the largest aperture you can afford. 

The exact type of object you want to check out could also guide your decision. Celestron suggests a minimum of 5 inches (120mm) for open star clusters and at least 8-11 inches (200-280 mm) for galaxies. 

Focal length & magnification

The focal length of your telescope is a measurement (measured in millimeters) of the distance between the primary lens or mirror and where the light comes in to focus at the other end. Focal length matters because it is part of what determines its magnification. 

While it might be somewhat counterintuitive, you don’t need crazy high magnification to view deep-space objects (DSOs). In fact, too much magnification may prevent you from seeing the object in the best light. Depending on what exactly you hope to check out, a focal length of 800 to 1250mm or so is best. 

Eyepiece

The other piece of the magnification puzzle is the eyepiece. Most telescopes will come with two eyepieces, providing different levels of magnification for better versatility. You can also purchase eyepieces separately if you want more options. 

Keep in mind that each telescope will have a minimum and maximum useful magnification. If you choose an eyepiece with too much magnification for your telescope, you will see objects larger, but it won’t be any sharper, so you may not get a very clear image. On the other hand, if you go with too little magnification, there will be a vignette around your view, and you won’t see the entire field of view. 

Without getting too into the weeds, there are also multiple types of eyepieces, each with its pros and cons. The most common ones that you’ll find are Barlow and Plössl eyepieces. Barlow lenses feature optical elements that increase magnification by either twice or triple as you step up. Plössl eyepieces offer a wider field of view, which makes them ideal for deep sky viewing. 

Optical design

There are many types of telescopes, but broadly speaking, there are three categories for consumers: Refractor, reflector, and catadioptric.

Refractor telescopes use lenses (typically made of glass) to allow the light to travel in a straight path from the front objective lens to the eyepiece at the back of the telescope. These are easy to use, reliable, and require little to no maintenance. However, if you want a large aperture, they are quite long. They also get expensive, especially for high-quality refractors, since the glass lenses are pricey to produce well. 

Reflector telescopes, including Newtonian and Dobsonian types, use mirrors to bounce light inside the device, allowing for a shorter design than refractor scopes. Mirrors are cheaper to make than glass lenses, so reflector telescopes are generally more affordable when compared to the same aperture as refractor scopes. They can, however, be quite bulky and heavy and need to be collimated (the process of aligning the mirrors), which adds a step before you can use your scope. 

Finally, catadioptric telescopes use both mirrors and lenses, allowing for a compact, portable design. Schmidt-Cassegrains and Maksutov-Cassegrains are two types of catadioptric telescopes that you’ll encounter. 

Mount type

The type of mount your telescope uses will impact how you can use it. At the risk of sounding like a broken record, there are three primary types you’ll encounter: Dobsonian, alt-azimuth, and equatorial.

Alt-azimuth mounts (also called alt-az) are the simplest and, therefore, most affordable. They allow for altitude (vertical) and azimuth (horizontal) adjustments. High-quality alt-az mounts also provide smooth tracking abilities; some even feature a motor for automated tracking. 

Dobsonian mounts use a platform much like a lazy susan. As a result, they need to be placed on sturdy, flat surfaces, such as a table. They provide excellent stability, as long as you have a good place to put it. They are not very portable, though, so these are best suited for homes where you can set it up and leave it. 

Finally, equatorial mounts counteract the Earth’s rotation, allowing you to focus on a single object and track it across the night sky. As a result, they are the preferred choice for serious astrophotography and long observations of single celestial objects. 

FAQs

Q: What makes a telescope good for deep-space observation?

The most important feature of a telescope for deep space observation is the aperture of the objective lens. Large apertures collect more light, necessary for faint objects far away. You’ll also need a sturdy mount to keep the telescope still throughout your viewing. If you want to view a single object for long periods, you’ll want to go with an equatorial mount or a smart telescope that can track automatically for you.

Q: Can you buy used telescopes?

You can absolutely buy used telescopes. Most telescopes require little maintenance, so purchasing a used one is typically a safe bet. It can save you a lot of money, allowing you to get into star gazing for less while reducing your impact on the environment in at least a small way.

Q: What can you see with a telescope for deep space?

Telescopes for deep space allow you to see beyond our solar system. These are typically called deep space objects, or DSOs, and include galaxies, nebulae, and star clusters. Keep in mind, however, that in order to view deep-space objects, you’ll need extremely dark skies. Light pollution of any almost level can prevent you from seeing distant objects. 

Final thoughts on the best telescopes for deep space

Telescopes for deep space have specific requirements that make them more expensive than basic scopes. But, if there’s room in your budget, they allow for epic stargazing, opening up new discoveries. And although they may be more advanced than cheap telescopes, most are still very beginner-friendly.

Steve Harvey, Taylor Swift, and other famous people's sloppy deepfakes are being used in sketchy 'medical card' YouTube videos.

Online scammers are using AI voice cloning technology to make it appear as if celebrities like Steve Harvey and Taylor Swift are encouraging fans to fall for medical benefits-related scams on YouTube. 404 Media first reported on the trend this week. These are just some of the latest examples of scammers harnessing increasingly accessible generative AI tools to target often economically impoverished communities and impersonate famous people for quick financial gain

404 Media was contacted by a tipster who pointed the publication towards more than 1,600 videos on YouTube where deepfaked celebrity voices work as well as non-celebrities to push the scams. Those videos, many of which remain active at time of writing, reportedly amassed 195 million views. The videos appear to violate several of YouTube’s policies, particularly those around misrepresentation and spam and deceptive practices. YouTube did not immediately respond to PopSci’s request for comment.  

How does the scam work?

The scammers try to trick viewers by using chopped up clips of celebrities and with voiceovers created with AI tools mimicking the celebrities’ own voices. Steve Harvey, Oprah, Taylor Swift, podcaster Joe Rogan, and comedian Kevin Hart all have deepfake versions of their voices appearing to promote the scam. Some of the videos don’t use celebrities deepfakes at all but instead appear to use a recurring cast of real humans pitching different variations of a similar story. The videos are often posted by YouTube accounts with misleading names like “USReliefGuide,” “ReliefConnection” and “Health Market Navigators.” 

“I’ve been telling you guys for months to claim this $6,400,” a deepfake clones attempting to impersonate Family Feud host Steve Harvey says. “Anyone can get this even if you don’t have a job!” That video alone, which was still on YouTube at time of writing, had racked up over 18 million views. 

Though the exact wording of the scams vary by video, they generally follow a basic template. First, the deepfaked celebrity or actor addresses the audience alerting them to a $6,400 end-of-the-year holiday stimulus check provided by the US government delivered via a “health spending card.” The celebrity voice then says anyone can apply for the stimulus so long as they are not already enrolled in Medicare or Medicaid. Viewers are then usually instructed to click a link to apply for the benefits. Like many effective scams, the video also introduces a sense of urgency by trying to convince viewers the bogus deal won’t last long. 

In reality, victims who click through to those links are often redirected to URLs with names like “secretsavingsusa.com” which are not actually affiliated with the US government. Reporters at PolitiFact called a signup number listed on one of those sites and spoke with an “unidentified agent” who asked them for their income, tax filing status, and birth date; all sensitive personal data that could potentially be used to engage in identity fraud. In some cases, the scammers reportedly ask for credit card numbers as well. The scam appears to use confusion over real government health tax credits as a hook to reel in victims. 

Numerous government programs and subsidies do exist to assist people in need, but generic claims offering “free money” from the US government are generally a red flag. Lowering costs associated with generative AI technology capable of creating somewhat convincing mimics of celebrities’ voices can make these scams even more convincing. The Federal Trade Commission (FTC) warned of this possibility in a blog post last year where it cited easy examples of fraudsters using deepfakes and voice clones to engage in extortion and financial fraud, among other illegal activities. A recent survey conducted by PLOS One last year found deepfake audio can already fool human listeners nearly 25% of the time

The FTC declined to comment on this recent string of celebrity deepfake scams. 

Affordable, easy to use AI tech has sparked a rise in celebrity deepfake scam

This isn’t the first case of deepfake celebrity scams, and it almost certainly won’t be the last. Hollywood legend Tom Hanks recently apologized to his fans on Instagram after a deepfake clone of himself was spotted promoting a dental plan scam. Not long after that, CBS anchor Gayle King said scammers were using similar deepfake methods to make it seem like she was endorsing a weight-loss product. More recently, scammers reportedly combined a AI clone of pop star Taylor Swift’s voice alongside real images of her using Le Creuset cookware to try and convince viewers to sign up for a kitchenware giveaway. Fans never received the shiny pots and pans. 

Lawmakers are scrambling to draft new laws or clarify existing legislation to try and address the growing issues. Several proposed bills like the Deepfakes Accountability Act and the No Fakes Act would give individuals more power to control digital representations for their likeness. Just this week, a bipartisan group of five House lawmakers introduced the No AI FRAUD Act which attempts to lay out a federal framework to protect individuals rights to their digital likeness, with an emphasis on artists and performers. Still, it’s unclear how likely those are to pass amid a flurry of new, quickly devised AI legislation entering Congress

Update 01/11/23 8:49am: A YouTube spokesperson got back to PopSci with this statement: “We are constantly working to enhance our enforcement systems in order to stay ahead of the latest trends and scam tactics, and ensure that we can respond to emerging threats quickly. We are reviewing the videos and ads shared with us and have already removed several for violating our policies and taken appropriate action against the associated accounts.”

On January 9, NASA leadership announced that it is delaying future missions to the moon. Originally slated to launch November 2024, the Artemis II mission that will send four astronauts around the moon has been postponed to September 2025. Meanwhile, the moon-landing mission Artemis III will now aim for September 2026 instead of late 2025. The Artemis IV mission remains on track for September 2028. 

[Related: Inside NASA’s messy plan to return to the moon by 2024.]

The agency cited safety concerns with its spacecraft and development issues with the lunar landers and spacesuits, both of which are being made by private industry. The announcement came within hours of private space company Astrobotic abandoning its attempt to land a spacecraft on the moon due to a fuel leak. Peregrine Mission One launched on January 8 as part of NASA’s commercial lunar program and the lander was intended to serve as a support scout for Artemis astronauts. 

When it eventually launches, Artemis II will not enter orbit around the moon the way that Apollo missions did. Instead, the Orion capsule will swing around the moon and use lunar gravity to sling the spacecraft back towards the Earth. The entire trip is expected to take about 10 days. In April 2023, NASA announced that the crew will be three of its astronauts—Victor Glover, Christina Koch, and Reid Wiseman—and Canadian astronaut Jeremy Hansen. 

NASA plans to land two astronauts on the moon near its south pole for the first time in its now rescheduled Artemis III mission. If successful, it will mark humanity’s first return to the lunar surface in over 50 years. 

“Safety is our top priority, and to give Artemis teams more time to work through the challenges with first-time developments, operations and integration, we’re going to give more time on Artemis II and III,” NASA Administrator Bill Nelson said in the live streamed briefing

The officials cited several technical issues for the delay, including the electronics in the life support system that will need to sustain the astronauts inside the Orion and the heat shield on the capsule. 

According to deputy associate administrator for NASA’s Moon to Mars program Amit Kshatriya, the heat shield issues that the Orion capsule experienced during the uncrewed Artemis 1 test flight around the moon in November and December 2022 have been a major concern while the data from that mission has been analyzed. They’ve found that while Orion’s heat shield sufficiently protected the capsule, a large amount of the shield was burned away from the spacecraft. 

[Related: Before the Artemis II crew can go to the moon, they need to master flying high above Earth.]

“We did see the off-nominal recession of some char that came off the heat shield, which we were not expecting,” Kshatriya said in the briefing. “Now, this heat shield is an ablative material—it is supposed to char—but it’s not what we were expecting, with some pieces of that char to be liberated from the vehicle.”

Over the past 10 years, NASA’s moon-landing effort has been delayed repeatedly. In December 2023, the Government Accountability Office reported that Artemis III’s targeted December 2025 lunar landing was unlikely. The accountability office cited an optimistic schedule for developing Space X’s Starship lunar lander and the spacesuits necessary for walking on the moon. In 2023, two Starship test launches failed to reach orbit. 
These delays have added billions of dollars to the cost of the program. According to the Associated Press, recent government audits project that it will cost $93 billion through 2025.

It may officially be Hollywood awards season, but NASA is also rolling out a red carpet of its own. On January 12 at 4pm EST, the agency will livestream the official public debut of its highly anticipated X-59 QueSST experimental aircraft. Designed alongside Lockheed Martin’s secretive Skunk Works division, the currently one-of-a-kind X-59 QueSST (short for Quiet SuperSonic Technology) is intended to demonstrate its potentially industry-shifting ability for human air travel at supersonic speeds sans sonic boom.

A sonic boom’s trademark thunderclap has long been associated with vehicles traveling faster than Mach 1. As a plane’s velocity surpasses the speed of sound, the shockwave formed by its wake results in a percussive noise capable of startling nearby humans and animals, as well as shattering windows if loud enough.

[Related: This experimental NASA plane will try to break the sound barrier—quietly.]

While sonic booms are permitted by certain military aircraft, commercial flights above the US have been prohibited from generating them since the Concorde jet’s retirement in 2003. The cutting edge X-59, in contrast, is designed to travel around 938 mph while only creating a “sonic thump” that is supposedly much quieter than an average sonic boom’s 110 decibels. NASA representatives previously estimated the X-59 will generate around 75 decibels of sound, or about as loud as slamming a car door.

The video livestream will begin at 4pm ET on January 12.

Engineers have spent years creating and honing the X-59’s state-of-the-art design. The experimental craft to be showcased on Friday is much smaller and more elongated than similar planes, measuring roughly 95-feet-long and less than 30-feet-wide. As New Scientist points out, that’s narrower than an F-16, but twice as long. The nose alone comprises nearly half plane’s length to ensure shockwaves generated near the front do not merge with waves created in the rear and thus emit a deafening boom. Because of this, the plane’s pilot will rely on 4K video screens inside the cockpit for their visuals to guide the aircraft.

It’s highly unlikely that X-59 will publicly take to the skies on Friday. Instead, the ceremony is meant to mark the beginning of a multiyear testing phase that will see the X-59 speed above “several US communities” selected by NASA’s QueSST team, who will then gather data and assess public reactions to the supposedly “gentle” sonic thump.

“This is the big reveal,” Catherine Bahm, manager of NASA’s Low Boom Flight Demonstrator project overseeing the X-59’s development and construction, said in a separate announcement. “The rollout is a huge milestone toward achieving the overarching goal of the QueSST mission to quiet the sonic boom.”

To call a sonic thump “quiet” may be a bit of an oversell, however. According to a 2022 Government Accountability Office (GAO) report, many people aren’t exactly pleased with daily disruptions caused by existing subsonic air travel, so it’s hard to envision sonic thumps being quieter than the average passenger jet. And even if the X-59’s volume proves nominal, environmental advocates continue to voice concerns over the potentially dramatic increase in carbon emissions that a new era of hypersonic flights could generate. In a letter penned to NASA administrator Bill Nelson by Public Employees for Environmental Responsibility (PEER) last year, the watchdog organization argued increased supersonic travel would be a “climate debacle.”

[Related: Air Force transport jets for VIPs could have a supersonic future.]

“Because the QueSSt mission is focused on the sonic boom challenge, the X-59 is not intended to be used as a tool to conduct research into other challenges of supersonic flight such as landing and takeoff noise, emissions and fuel burn. These challenges are being explored in other NASA research,” NASA representatives told The Register in July 2023.

Even if everything goes smoothly, however, it is unlikely that a fleet of X-59 jets will be zipping over everyone’s heads anytime soon. In 2021, a Lockheed Martin Skunk Works manager estimated that supersonic air travel won’t feasibly make its potential return until around 2035.

First, however, is Friday’s scheduled pomp and circumstance. Viewers can tune into NASA’s livestream of the event at 4pm ET on YouTube, as well as through the agency’s NASA+ streaming service, NASA app, and website.

Apple has designed its phones and computers to work together as seamlessly as possible.   Users who have both a Mac and an iPhone (and maybe an iPad and Apple Watch thrown in as well) enjoy some truly convenient synergies. That’s especially true for iOS and MacOS devices–iPhone apps will run on the Mac if you know how to set it up.

There are a few caveats to bear in mind: The developer of the iPhone app must have added Mac compatibility, and you must be running a Mac with an Apple chipset inside (so not one of the older Intel-powered ones). WIth those footnotes out of the way, you can get started with running apps on both platforms.

This comes in useful in a few different ways, not least because it enables you to use a phone app on a bigger screen, without having to keep pulling your phone out or unlocking it. Some iPhone apps have proper desktop apps or web apps to use of course, but sometimes the mobile app option works best.

Finding apps

If you open up the App Store on macOS, then click your name down in the lower left corner and switch to the iPhone & iPad Apps tab, you’ll see a list of all the apps you’ve ever installed on an Apple-made phone or tablet that can also be installed on macOS. Click on any of the items listed to take a closer look at its description and other information.

Those apps that are labeled with just “Designed for iPhone” or “Designed for iPad” and nothing else have also been optimized to work on macOS. Those that haven’t been optimized will also have a “Not verified for macOS” note next to them. You can still install these apps on your Mac, but the quality of the user experience may vary. 

With apps that don’t appear at all, that’ll be because the developer has opted out of making them available on macOS. This includes some of the big ones, such as Instagram and Google Maps—presumably because their developers want you to use the web versions of their apps instead.

To install an iPhone or iPad app on your Mac, just click the blue download button, which looks like a cloud with a downward arrow coming out of it. After the download has finished, you can then click Open to launch it. The app appears in its own window (which you may be able to resize), with its own menu options at the top.

You can also look for apps that you’ve never installed on an iPhone or an iPad: Click inside the search box in the top left corner, then type out the name of the app you’re looking for. On the results screen, you’ll need to switch to the iPhone & iPad Apps tab to find the apps developed first and foremost for iOS and iPadOS.

Running apps

macOS gives you some help with controlling apps and games.

Some iPhone apps are easier than others to run on a Mac—obviously you’ve not got the touchscreen functionality, so you might have to take some time working out the trackpad (or mouse) gestures and keyboard combinations that will enable you to control the app properly in its new desktop environment.

Apps that require a lot of typing are actually more straightforward on a Mac, because you’ve got a full-sized, physical keyboard. Take iOS apps such as Letterboxd or Airbnb for example: They both work on macOS if you don’t want to use the respective websites, and running searches or entering details is much quicker than it is on a phone touchscreen.

The macOS platform does give you a bit of help with touchscreen inputs: If you hold down the Option key on your keyboard, for example, you’re able to use a trackpad as a virtual touchscreen, which can make the control of certain apps and games more manageable. In most apps, clicks equate to taps, and swipes on a trackpad match swipes on a screen.

With an app running, you can click on its name on the menu bar and then choose Settings to configure it further: You can set how opening web links is handled under the General tab, while under Touch Alternatives you can set up different ways that touchscreen inputs are replicated on a keyboard (including the Option trick mentioned above).

Games designed for iPhones and iPads work in the same way as apps, so this is also a good way of enjoying some leisure time on your Mac. Well-known titles such as Crossy Road, Monument Valley, and Two Dots are available on macOS, for example, and are fairly easy to operate with a keyboard and trackpad (or mouse).

These extinct, nearly 10-foot-tall apes could not adapt to shifting seasons https://www.popsci.com/environment/extinct-10-foot-tall-apes/ Wed, 10 Jan 2024 16:01:43 +0000 https://www.popsci.com/?p=598137

Beginning about 2.6 million years ago, giant primates almost 10 feet tall weighing 551 pounds roamed the plains of southern China. Gigantopithecus blacki (G. blacki) towered over today’s largest monkeys by about five feet and is believed to be the largest primate to ever roam the Earth. However, it went extinct just as other primates–like orangutans–were thriving. 

[Related: These primate ancestors were totally chill with a colder climate.]

Now, a team of scientists from China, Australia, and the United States believe that this giant ape went extinct between 295,000 and 215,000 years ago because it could not adapt its food preferences and behaviors and was vulnerable to extreme changes in the planet’s climate. The findings are detailed in a study published January 10 in the journal Nature

“The story of G. blacki is an enigma in paleontology–how could such a mighty creature go extinct at a time when other primates were adapting and surviving? The unresolved cause of its disappearance has become the Holy Grail in this discipline,” Yingqi Zhang, study co-author and Institute of Vertebrate Palaeontology and Palaeoanthropology at the Chinese Academy of Sciences (IVPP) paleontologist, said in a statement

Seasonal shifts 

Roughly 700,000 to 600,000 years ago, the rich forest environment that G. blacki lived in began to change. The new study proposes that as Earth’s four seasons began to strengthen and G. blacki’s habitat saw more variability in temperature and precipitation, the structure of these forest communities began to change. 

In response, G. blacki’s close relatives the orangutans adapted their habitat preferences, behavior, and size over time. However, G. blacki was not quite as nimble. Based on its dental anatomy, these giant apes were herbivores that had adapted to eat fibrous foods like fruits. However, when its favorite food sources were not available, the team believes that G. blacki relied on a less nutritious backup source of sustenance, decreasing the diversity of its food. They likely suffered from a reduced geographic range for foraging, became less mobile, and saw chronic stress and dwindling numbers. 

G. blacki was the ultimate specialist, compared to the more agile adapters like orangutans,  and this ultimately led to its demise,” said Zhang. 

Honing in on a date

G. blacki left behind roughly 2,000 fossilized teeth and four jawbones that helped paleontologists put together the story of G. blacki’s time on Earth, but more precise dating of these remains was needed to determine its extinction story. To find definitive evidence of their extinction, the team took on a large-scale project that explored 22 cave sites in a wide region of Guangxi Province in southern China. 

[Related: Nice chimps finish last—so why aren’t all of them mean?]

Determining the exact time when a species disappears from the fossil record helps paleontologists determine a timeframe that they can work to rebuild from other evidence. 

“Without robust dating, you are simply looking for clues in the wrong places,” Kira Westaway, a study co-author and geochronologist at Macquarie University in Australia, said in a statement

In the study, the team used six dating techniques the samples of cave sediments and teeth fossils. The techniques produced 157 radiometric ages that were combined with eight sources of environmental and behavioral evidence. They took this combined figure and applied it to 11 caves that had evidence of G blacki in them and 11 caves of a similar age range that did not have any remains of G. blacki.

The primary technique that helped the team hone in on a date range was luminescence dating. It measures a light-sensitive signal that is found in the burial sediments that encased the G. blacki fossils. Uranium series and electron-spin resonance were also critical in dating the G. blacki teeth themselves. 

“By direct-dating the fossil remains, we confirmed their age aligns with the luminescence sequence in the sediments where they were found, giving us a comprehensive and reliable chronology for the extinction of G. blacki,” Renaud Joannes-Boyau, a study co-author and geochronologist at Southern Cross University  in Australia, said in a statement. 

Building a world from teeth and pollen 

Researchers also used a detailed pollen analysis to reconstruct what the plant life looked like hundreds of thousands of years ago, a stable isotope analysis of the teeth, and a detailed analysis of the cave sediments to re-create the environmental conditions leading up to the time G blacki went extinct. Trace element and dental microwear textural analysis of the apes’ teeth enabled the team to model what G. blacki’s behavior likely looked like when they were flourishing, compared to their demise. 

[Related: An ‘ancestral bottleneck’ took out nearly 99 percent of the human population 800,000 years ago.]

“Teeth provide a staggering insight into the behavior of the species indicating stress, diversity of food sources, and repeated behaviors,” said Joannes-Boyau.

The dates of the fossils combined with the pollen and teeth analysis revealed that G.blacki went extinct between 295,000 and 215,000 years ago, earlier than scientists previously assumed. The team believes that studying their lack of adaptation has implications for today’s changing climate and the need for adaptation. 

“With the threat of a sixth mass extinction event looming over us, there is an urgent need to understand why species go extinct,” said Westaway. “Exploring the reasons for past unresolved extinctions gives us a good starting point to understand primate resilience and the fate of other large animals, in the past and future.”

Top neuroscience labs are adapting new and unexpected tools to gain a deeper understanding of how mice, and ultimately humans, react to different drug treatments.

Back in 2013, Sandeep Robert “Bob” Datta was working in his neurobiology lab at Harvard Medical School in Boston when he made the fateful decision to send his student Alex Wiltschko to the Best Buy up the street. Wiltschko was on a mission to purchase an Xbox Kinect camera, designed to pick up players’ body movements for video games like Just Dance and FIFA. He plunked down about $150 and walked out with it. The unassuming piece of consumer electronics would determine the lab’s direction in the coming decade and beyond. 

It also placed the team within a growing scientific movement at the intersection of artificial intelligence, neuroscience, and animal behavior—a field poised to change the way researchers use other creatures to study human health conditions. The Datta Lab is learning to track the intricate nuances of mouse movement and understand the basics of how the mammal brain creates behavior, untangling the neuroscience of different health conditions and ultimately developing new treatments for people. This area of research relies on so-called “computer vision” to analyze video footage of animals and detect behavior patterns imperceptible to the unaided eye. Computer vision can also be used to auto-detect cell types, addressing a persistent problem for researchers who study complex tissues in, for example, cancers and gut microbiomes.

In the early 2010s, Datta’s lab was interrogating how smell, “the sense that is most important to most animals” and the one that mice can’t survive without, drives the rodents’ responses to manipulations in their environment. Human observers traditionally track mouse behavior and record their observations—how many times a mouse freezes in fear, how often it rears up to explore its enclosure, how long it spends grooming, how many marbles it buries. Datta wanted to move beyond the movements visible to the unaided eye and use video cameras to track and compute whether a rodent avoids an odor (that of predator urine, for instance) or is attracted to it (like the smell of roses). The tools available at the time—overhead 2D cameras that tracked each animal as a single point—didn’t yield sufficiently detailed data.

“Even in an arena in the dark, where there’s no stimuli at all, [mice] just generate these incredible behavioral dynamics—none of which are being captured by, like, a dot bouncing around on the screen,” says Datta. So Wiltschko identified the Xbox Kinect camera as a potential solution. Soon after its introduction in 2010, people began hacking the hardware for science and entertainment purposes. It was fitting for Datta’s lab to use it to track mice: It can record in the dark using infrared light (mice move around much more when it’s darker) and can see in 3D when mounted overhead by measuring how far an object is from the sensor. This enabled Datta’s team to follow the subjects when they ran around, reared up, or hunkered down. As it analyzed its initial results, it realized that the Kinect camera recorded the animals’ movements with a richness that 2D cameras couldn’t capture.

“That got us thinking that if we could just somehow identify regularities in the data, we might be able to identify motifs or modules of action,” Datta says. Looking at the raw pixel counts from the Kinect sensor, even as compressed image files and without any sophisticated analysis, they began seeing these regularities. With or without an odor being introduced, every few hundred milliseconds, mice would switch between different types of movement—rearing, bobbing their heads, turning. For several years after the first Kinect tests, Datta and his team tried to develop software to identify and record the underlying elements of the basic components of movement the animals string together to create behavior.

But they kept hitting dead ends.

“There are many, many ways you can take data and divide it up into piles. And we tried many of those ways, many for years,” Datta recalls. “And we had many, many false starts.”

They tried categorizing results based on the animals’ poses from single frames of video, but that approach ignored movement—“the thing that makes behavior magic,” according to Datta. So they abandoned that strategy and started thinking about the smaller motions that last fractions of a second and constitute behavior, analyzing them in sequence. This was the key: the recognition that movement is both discrete and continuous, made up of units but also fluid. 

So they started working with machine learning tools that would respect this dual identity. In 2020, seven years after that fateful trip to Best Buy, Datta’s lab published a scientific paper describing the resulting program, called MoSeq (short for “motion sequencing,” evoking the precision of genetic sequencing). In this paper, they demonstrated their technique could identify the subsecond movements, or “syllables,” as they call them, that make up mouse behavior when they’re strung together into sequences. By detecting when a mouse reared, paused, or darted away, the Kinect opened up new possibilities for decoding the “grammar” of animal behavior.

Computer visionaries

In the far corner of the Datta Lab, which still resides at Harvard Medical School, Ph.D. student Maya Jay pulls back a black curtain, revealing a small room bathed in soft reddish-orange light. To the right sit three identical assemblies made of black buckets nestled inside metal frames. Over each bucket hangs a Microsoft Xbox Kinect camera, as well as a fiber-optic cable connected to a laser light source used to manipulate brain activity. The depth-sensing function of the cameras is the crucial element at play. Whereas a typical digital video captures things like color, the images produced by the Kinect camera actually show the height of the animal off the floor, Jay says—for instance, when it bobs its head or rears up on its hind legs. 

Microsoft discontinued the Xbox Kinect cameras in 2017 and has stopped supporting the gadget with software updates. But Datta’s lab developed its own software packages, so it doesn’t rely on Microsoft to keep the cameras running, Jay says. The lab also runs its own software for the Azure Kinect, a successor to the original Kinect that the team also employs—though it was also discontinued, in 2023. Across the lab from the Xbox Kinect rigs sits a six-camera Azure setup that records mice from all angles, including from below, to generate either highly precise 2D images incorporating data from various angles or 3D images.

In the case of MoSeq and other computer vision tools, motion recordings are often analyzed in conjunction with manipulations to the brain, where sensory and motor functions are rooted in distinct modules, and neural-activity readings. When disruptions in brain circuits, either from drugs administered in the lab or edits to genes that mice share with humans, lead to changes in behaviors, it suggests a connection between the two. This makes it possible for researchers to determine which circuits in the brain are associated with certain types of behavior, as well as how medications are working on these circuits.

In 2023, Datta’s lab published two papers detailing how MoSeq can contribute to new insights into an organism’s internal wiring. In one, the team found that, for at least some mice in some situations, differences in mouse behavior are influenced way more by individual variation in the brain circuits involved with exploration than by sex or reproductive cycles. In another, manipulating the neurotransmitter dopamine suggested that this chemical messenger associated with the brain’s reward system supports spontaneous behavior in much the same way it influences goal-directed behaviors. The idea is that little bits of dopamine are constantly being secreted to structure behavior, contrary to the popular perception of dopamine as a momentous reward. The researchers did not compare MoSeq to human observations, but it performed comparably in another set of experiments in a paper that has yet to be published.

These studies probed some basic principles of mouse neurobiology, but many experts in this field say MoSeq and similar tools could broadly revolutionize animal and human health research in the near future. 

With computer vision tools, mouse behavioral tests can run in a fraction of the time that would be required with human observers. This tech comes at a time when multiple forces are calling animal testing into question. The United States Food and Drug Administration (FDA) recently changed its rules on drug testing to consider alternatives to animal testing as prerequisites for human clinical trials. Some experts, however, doubt that stand-ins such as organs on chips are advanced enough to replace model organisms yet. But the need exists. Beyond welfare and ethical concerns, the vast majority of clinical trials fail to show benefits in humans and sometimes produce dangerous and unforeseen side effects, even after promising tests on mice or other models. Proponents say computer vision tools could improve the quality of medical research and reduce the suffering of lab animals by detecting their discomfort in experimental conditions and clocking the effects of treatments with greater sensitivity than conventional observations.

Further fueling scientists’ excitement, some see computer vision tools as a means of measuring the effects of optogenetics and chemogenetics, techniques that use engineered molecules to make select brain cells turn on in response to light and chemicals, respectively. These biomedical approaches have revolutionized neuroscience in the past decade by enabling scientists to precisely manipulate brain circuits, in turn helping them investigate the specific networks and neurons involved in behavioral and cognitive processes. “This second wave of behavior quantification is the other half of the coin that everyone was missing,” says Greg Corder, assistant professor of psychiatry at the University of Pennsylvania. Others agree that these computer vision tools are the missing piece to track the effects of gene editing in the lab.

“[These technologies] truly are integrated and converge,” agrees Clifford Woolf, a neurobiologist at Harvard Medical School who works with his own supervised computer vision tools in his pain research.

But is artificial intelligence ready to take over the task of tracking animal behavior and interpreting its meaning? And is it identifying meaningful connections between behavior and neurological activity just yet?

These are the questions at the heart of a tension between supervised and unsupervised AI models. Machine learning algorithms find patterns in data at speeds and scales that would be difficult or impossible for humans. Unsupervised machine learning algorithms identify any and all motifs in datasets, whereas supervised ones are trained by humans to identify specific categories. In mouse terms, this means unsupervised AIs will flag every unique movement or behavior, but supervised ones will pinpoint only those that researchers are interested in.

The major advantage of unsupervised approaches for mouse research is that people may not notice action that takes place on the subsecond scale. “When we analyze behavior types, we often actually are based on the experimenters’ judgment of the behavior type, rather than mathematical clustering,” says Bing Ye, a neuroscientist at the University of Michigan whose team developed LabGym, a supervised machine learning tool for mice and other animals, including rats and fruit fly larvae. The number of behavioral clusters that can be analyzed, too, is limited by human trainers. On the other hand, he says, live experts may be the most qualified to recognize behaviors of note. For this reason, he advocates transparency: publishing training datasets, the classification parameters that a supervised algorithm learns on, with any studies. That way, if experts disagree with how a tool identifies behaviors, the publicly available data provide a solid foundation for scientific debate.

Mu Yang, a neurobiologist at Columbia University and the director of the Mouse NeuroBehavior Core, a mouse behavior testing facility, is wary of trusting AI to do the work of humans until the machines have proved reliable. She is a traditional mouse behavior expert, trained to detect the animals’ subtleties with her own eyes. Yang knows that the way a rodent expresses an internal state, like fear, can change depending on its context. This is true for humans too. “Whether you’re in your house or…in a dark alley in a strange city, your fear behavior will look different,” Yang explains. In other words, a mouse may simply pause or it may freeze in fear, but an AI could be hard-pressed to tell the difference. One of the other challenges in tracking the animals’ behaviors, she says, is that testing different drugs on them may cause them to exhibit actions that are not seen in nature. Before AIs can be trusted to track these novel behaviors or movements, machine learning programs like MoSeq need to be vetted to ensure they can reliably track good old-fashioned mouse behaviors like grooming. 

Yang draws a comparison to a chef, saying that you can’t win a Michelin star if you haven’t proved yourself as a short-order diner cook. “If I haven’t seen you making eggs and pancakes, you can talk about caviar and Kobe beef all you want, I still don’t know if I trust you to do that.”

For now, as to whether MoSeq can make eggs and pancakes, “I don’t know how you’d know,” Datta says. “We’ve articulated some standards that we think are useful. MoSeq meets those benchmarks.”

Putting the tech to the test

There are a couple of ways, Datta says, to determine benchmarks—measures of whether an unsupervised AI is correctly or usefully describing animal behavior. “One is by asking whether or not the content of the behavioral description that you get [from AI] does better or worse at allowing you to discriminate among [different] patterns of behavior that you know should occur.” His team did this in the first big MoSeq study: It gave mice different medicines and used the drugs’ expected effects to determine whether MoSeq was capturing them. But that’s a pretty low bar, Datta admits—a starting point. “There are very few behavioral characterization methods that wouldn’t be able to tell a mouse on high-dose amphetamine from a control.” 

The real benchmark of these tools, he says, will be whether they can provide insight into how a mouse’s brain organizes behavior. To put it another way, the scientifically useful descriptions of behavior will predict something about what’s happening in the brain.

Explainability, the idea that machine learning will identify behaviors experts can link to expected behaviors, is a big advantage of supervised algorithms, says Vivek Kumar, associate professor at the biomedical research nonprofit Jackson Laboratory, one of the main suppliers of lab mice. His team used this approach, but he sees training supervised classifiers after unsupervised learning as a good compromise. The unsupervised learning can reveal elements that human observers may miss, and then supervised classifiers can take advantage of human judgment and knowledge to make sure that what an algorithm identifies is actually meaningful.

“It’s not magic”

MoSeq isn’t the first or only computer vision tool under development for quantifying animal behavior. In fact, the field is booming as AI tools become more powerful and easier to use. We already mentioned Bing Ye and LabGym; the lab of Eric Yttri at Carnegie Mellon University has developed B-SOiD; the lab of Mackenzie Mathis at École Polytechnique Fédérale de Lausanne has DeepLabCut; and the Jackson Laboratory is developing (and has patented) its own computer vision tools. Last year Kumar and his colleagues used machine vision to develop a frailty index for mice, an assessment that is notoriously sensitive to human error.

Each of these automated systems has proved powerful in its own way. For example, B-SOiD, which is unsupervised, identified the three main types of mouse grooming without being trained in these basic behaviors. 

“That’s probably a good benchmark,” Yang says. “I guess you can say, like the egg and pancake.”

Mathis, who developed DeepLabCut, emphasizes that carefully picking data sources is critical for making the most of these tools. “It’s not magic,” she says. “It can make mistakes, and your trained neural networks are only as good as the data you give [them].”

And while the toolmakers are still honing their technologies, even more labs are hard at work deploying them in mouse research with specific questions and targets in mind. Broadly, the long-term goal is to aid in the discovery of drugs that will treat psychiatric and neurological conditions. 

Some have already experienced vast improvements in running their experiments. One of the problems of traditional mouse research is that animals are put through unnatural tasks like running mazes and taking object recognition tests that “ignore the intrinsic richness” of behavior, says Cheng Li, professor of anesthesiology at Tongji University in Shanghai. His team found that feeding MoSeq videos of spontaneous rodent behavior along with more traditional task-oriented behaviors yielded a detailed description of the mouse version of postoperative delirium, the most common central nervous system surgical complication among elderly people. 

Meanwhile, LabGym is being used to study sudden unexpected death in epilepsy in the lab of Bill Nobis at Vanderbilt University Medical Center. After being trained on videos of mouse seizures, the program detects them “every time,” Nobis says.

Easing their pain

Computer vision has also become a major instrument for pain research, helping to untangle the brain’s pathways involved in different types of pain and treat human ailments with new or existing drugs. And despite the FDA rule change in early 2023, the total elimination of animal testing is unlikely, Woolf says, especially in developing novel medicines. By detecting subtle behavioral signs of pain, computer vision tools stand to reduce animal suffering. “We can monitor the changes in them and ensure that we’re not producing an overwhelming, painful situation—all we want is enough pain that we can measure it,” he explains. “We would not do anything to a mouse that we wouldn’t do to a human, in general.”

His team used supervised machine learning to track behavioral signatures of pain in mice and show when medications have alleviated their discomfort, according to a 2022 paper in the journal Pain. One of the problems with measuring pain in lab animals, rather than humans, is that the creatures can’t report their level of suffering, Woolf says. Scientists long believed that, proportional to body weight, the amount of medicine required to relieve pain is much higher in mice than in humans. But it turns out that if your computer vision algorithms can measure the sensation relatively accurately—and Woolf says his team’s can—then you actually detect signs of pain relief at much more comparable doses, potentially reducing the level of pain inflicted to conduct this research. Measuring pain and assessing pain medicine in lab animals is so challenging that most large pharmaceutical companies have abandoned the area as too risky and expensive, he adds. “We hope this new approach is going to bring them back in.”

Corder’s lab at the University of Pennsylvania is working on pain too, but using the unsupervised B-SOiD in conjunction with DeepLabCut. In unpublished work, the team had DeepLabCut visualize mice as skeletal stick figures, then had B-SOiD identify 13 different pain-related behaviors like licking or biting limbs. Supervised machine learning will help make his team’s work more reliable, Corder says, as B-SOiD needs instruction to differentiate these behaviors from, say, genital licking, a routine hygiene behavior. (Yttri, the co-creator of B-SOiD, says supervision will be part of the new version of his software.) 

As computer vision tools continue to evolve, they could even help reduce the number of animals required for research, says FDA spokesperson Lauren-Jei McCarthy. “The agency is very much aligned with efforts to replace, reduce, or refine animal studies through the use of appropriately validated technologies.”

If you build it, they will come

MoSeq’s next upgrade, which has been submitted to an academic journal and is under review, will try something similar to what Corder’s lab did: It will meld its unsupervised approach with keypoint detection, a computer vision method that highlights crucial points in an object like the body of a mouse. This particular approach employs the rig of six Kinect Azure cameras instead of the Datta lab’s classic Xbox Kinect camera rigs.

An advantage of this approach, Datta says, is that it can be applied to existing 2D video, meaning that all the petabytes of archival mouse data from past experiments could be opened up to analysis without the cost of running new experiments on mice. “That would be huge,” Corder agrees.

Datta’s certainty increases as he rattles off some of his team’s accomplishments with AI and mouse behavior in the past few years. “Can we use MoSeq to identify genetic mutants and distinguish them from wild types? —mice with genetics as they appear in nature. This was the subject of a 2020 paper in Nature Neuroscience, which showed that the algorithm can accurately discern mice with an autism-linked gene mutation from those with typical genetics. “Can we make predictions about neural activity?” The Datta Lab checked this off its bucket list just this year in its dopamine study. Abandoning the hedging so typical of scientists, he confidently declares, “All of that is true. I think in this sense, MoSeq can make eggs and pancakes.”

Bottled water has up to 100 times more plastic particles than previously thought https://www.popsci.com/environment/water-bottle-microplastics/ Wed, 10 Jan 2024 14:00:00 +0000 https://www.popsci.com/?p=598015

New research shows that every liter of bottled water contains 240,000 microscopic pieces of plastic.

This story was originally published by Grist. Sign up for Grist’s weekly newsletter here.

At this point, it’s common knowledge that bottled water contains microplastics—fragments of the insidious material that can be as small as a bacterial cell. But the problem is much worse than previously known: It turns out that bottled water harbors hundreds of thousands of even tinier pieces of the stuff.

paper published Monday used a novel technique to analyze one-liter samples of bottled water for plastic granules, going down to just 50 to 100 nanometers in length—roughly the width of a virus. They found nearly a quarter of a million of these tiny particles per liter, about 10 to 100 times more than previously published estimates.

“We’ve opened up a whole new world,” Wei Min, one of the paper’s authors and a chemistry professor at Columbia University, told Grist. Until now, scientists lacked a quick and efficient way to identify nanoplastics, hindering research on their health and environmental impacts. 

To conduct their analysis, researchers at Columbia and Rutgers universities filtered bottled water from three different brands through an ultrafine membrane. They then shone two lasers, calibrated to recognize the chemical bonds binding the nanoplastic particles, onto the membrane. Then it was a simple matter of counting all the different particles of plastic. They estimated that a typical one-liter bottle contains 240,000 of them.

Sherri Mason, an associate research professor at Penn State Erie who studies microplastics but was not involved in the new research, called the technique “groundbreaking.”

”I was blown away,” she told Grist. “It’s just really good.”

What’s more, the researchers were able to differentiate between types of nanoplastic. To their surprise, most of the particles were not polyethylene terephthalate, or PET—the material most water bottles are made of. Rather, they found more particles of polyamide (a type of nylon) and polystyrene, suggesting that the pollutants are, in a bit of irony, getting into bottled water as a result of the filling and purification process. 

Polyamide also made up the bulk of the contamination by mass for two of the bottled water brands; the third brand showed a higher level of PET.

The findings have significant implications for human health, since nanoplastics are small enough to pass through the gastrointestinal tract and lungs. After entering the bloodstream, they can lodge in the heart and brain, and can even cross through the placenta to infiltrate unborn babies. It’s not yet clear how the particles impact the body, but toxicologists worry that they could leach chemicals or release pathogens that they picked up while floating around in the environment. Some research suggests potential damage to DNA and the brain, as well as to the immune, reproductive, and nervous systems.

“We know we’re getting exposed, but we don’t know the toxicity of the exposures,” said Beizhan Yan, another of the paper’s co-authors and an environmental chemist at Columbia University. He called for further collaboration with toxicologists and public health researchers to better characterize the risks. For now, he said he opts for tap water whenever possible; it tends to have less plastic contamination.

Wei sees a handful of promising directions for further research. First, his team could expand the number of plastic polymers it can identify using the laser-microscope technique; their most recent paper only looked at seven. They could also look for nanoplastics in other places, like packaged food or wastewater from washing machines, and improve the technology to detect even smaller particles.

“Fifty to 100 nanometers is our current detection limit, but that’s not a hard stop,” Wei said. 

Mason said the research should inspire action from U.S. policymakers, who have the power to limit plastic production by supporting the Break Free From Plastic Pollution Act—a federal bill that was reintroduced in Congress for the third time last October—or by endorsing plastic reduction as part of the United Nations’ global plastics treaty.

“I don’t want a plasticized world,” she said. “We need to make it clear to our representatives that we need to chart a new path forward.”

At 1:03 p.m. EST Astrobotic issued an update saying that the mission will likely not go on as planned, as the lunar lander is experiencing a failure within its propulsion system.

Later, Astrobotic announced that Peregrine is suffering a critical fuel leak and has less than two days of fuel left.  An image taken by the lander in space showed damaged insulation on the spacecraft, which indicates a leak in Peregrine’s propulsion system.

“An ongoing propellant leak is causing the spacecraft’s Attitude Control System (ACS) thrusters to operate well beyond their expected service life cycles to keep the lander from an uncontrollable tumble,” the company wrote.

On Tuesday January 9, Astrobiotic announced that it would be abandoning its attempt for a soft landing on the moon. The lunar lander was slated to attempt to make the first soft landing on the moon by the United States since 1972. Peregrine’s mission is to study the lunar surface ahead of future human missions to the moon.

The launch also began a new chapter in the age of private space exploration. The United Launch Alliance is a joint venture between Boeing and Lockheed Martin, with the Vulcan rocket designed to replace two older rockets and compete with SpaceX. The private company owned by Elon Musk sent close to 100 rockets into orbit in 2023 alone. The United States Space Force is also counting on the Vulcan Centaur rocket to launch spy satellites and other spacecraft that Space Force believes are in the interest of national security. 

The Peregrine lander was built by Pittsburgh-based space robotics firm Astrobotic and aimed to become the first lunar lander constructed by a private company. This is also the first mission to fly under NASA’s Commercial Lunar Payload Services (CLPS) initiative, where NASA pays private companies to send scientific equipment to the moon.

“It’s a dream … For 16 years we’ve been pushing for this moment today,” said Astrobotic CEO John Thornton during a webcast of the launch according to CNN. “And along the way, we had a lot of hard challenges that we had to overcome and a lot of people doubted us along the way. But our team and the people that supported us believed in the mission, and they created this beautiful moment that we’re seeing today.”

Peregrine has a total of 20 payloads on board, five for NASA and 15 others. They include five small moon rovers and the first Latin American scientific instruments attempting to reach the lunar surface. If successful, the technology on board will measure properties including radiation levels, magnetic field, ice and water on the surface and subsurface, and a layer of gas called the exosphere. A better understanding of the exosphere and the moon’s surface is expected to help minimize risks when humans return to its surface, as early as 2025.  

Several non-scientific payloads are aboard as well, including a lunar dream capsule with over 180,000 messages from children around the world, a chunk of Mount Everest, and a physical coin containing one bitcoin.

Controversially, Peregrine is carrying human remains on behalf of commercial space burial companies Celestis and Elysium Space. Celestis offers to carry ashes to the moon for prices starting at more than $10,000. The 265 capsules include human remains from Star Trek creator Gene Roddenberry and original cast members and DNA samples from three former US presidents–George Washington, Dwight Eisenhower, and John F. Kennedy. Bringing human remains to the moon is strongly opposed by the Navajo Nation, as allowing human remains to touch the lunar surface would be desecration of a body that many tribes consider sacred. In a statement on January 4, Navajo Nation president Buu Nygren said that NASA or other government officials should address the tribe’s concerns ahead of the launch. 

“The moon holds a sacred place in Navajo cosmology,” Nygren wrote. “The suggestion of transforming it into a resting place for human remains is deeply disturbing and unacceptable to our people and many other tribal nations.”

[Related: The moon is 40 million years older than we thought, according to crystals collected by Apollo astronauts.]

According to The New York Times, NASA officials said in a news conference that they were not in charge of this mission and do not have a direct say on the payloads that were sold on Peregrine. ”There’s an intergovernmental meeting being set up with the Navajo Nation that NASA will support,” deputy associate administrator for exploration at NASA Joel Kearns said on January 4.

Peregrine 1 was originally scheduled to touch down on the surface of the moon on February 23, near Sinus Viscositatis–or the Bay of Stickiness. This area is named for rock domes that were potentially created by viscous lava.

Update January 9, 2:39PM: Additional information from the company about the technical problems has been added.

The FTC wants your help fighting AI vocal cloning scams https://www.popsci.com/technology/ftc-ai-vocal-clone-contest/ Mon, 08 Jan 2024 17:21:51 +0000 https://www.popsci.com/?p=597756

The Federal Trade Commission is on the hunt for creative ideas tackling one of scam artists’ most cutting edge tools, and will dole out as much as $25,000 for the most promising pitch. First announced last fall, submissions are now officially open for the FTC’s Voice Cloning Challenge. The contest is looking for ideas for “preventing, monitoring, and evaluating malicious” AI vocal cloning abuses.

Artificial intelligence’s ability to analyze and imitate human voices is advancing at a breakneck pace—deepfaked audio already appears capable of fooling as many as 1-in-4 unsuspecting listeners into thinking a voice is human-generated. And while the technology shows immense promise in scenarios such as providing natural-sounding communication for patients suffering from various vocal impairments, scammers can use the very same programs for selfish gains. In April 2023, for example, con artists attempted to target a mother in Arizona for ransom by using AI audio deepfakes to fabricate her daughter’s kidnapping. Meanwhile, AI imitations present a host of potential issues for creative professionals like musicians and actors, whose livelihoods could be threatened by comparatively cheap imitations.

[Related: Deepfake audio already fools people nearly 25 percent of the time.]

Remaining educated about the latest in AI vocal cloning capabilities is helpful, but that can only do so much as a reactive protection measure. To keep up with the industry, the FTC initially announced its Voice Cloning Challenge in November 2023, which sought to “foster breakthrough ideas on preventing, monitoring, and evaluating malicious voice cloning.” The contest’s submission portal launched on January 2, and will remain open until 8pm ET on January 12.

According to the FTC, judges will evaluate each submission based on its feasibility, the idea’s focus on reducing consumer burden and liability, as well as each pitch’s potential resilience in the face of such a quickly changing technological landscape. Written proposals must include a less-than-one page abstract alongside a more detailed description under 10 pages in length explaining their potential product, policy, or procedure. Contestants are also allowed to include a video clip describing or demonstrating how their idea would work.

In order to be considered for the $25,000 grand prize—alongside a $4,000 runner-up award and up to three, $2,000 honorable mentions—submitted projects must address at least one of the three following areas of vocal cloning concerns, according to the official guidelines

  • Prevention or authentication methods that would limit unauthorized vocal cloning users
  • Real-time detection or monitoring capabilities
  • Post-use evaluation options to assess if audio clips contain cloned voices

The Voice Cloning Challenge is the fifth of such contests overseen by the FTC thanks to funding through the America Competes Act, which allocated money for various government agencies to sponsor competitions focused on technological innovation. Previous, similar solicitations focused on reducing illegal robocalls, as well as bolstering security for users of Internet of Things devices.

[Related: AI voice filters can make you sound like anyone—and anyone sound like you.]

Winners are expected to be announced within 90 days after the contest’s deadline. A word of caution to any aspiring visionaries, however: if your submission includes actual examples of AI vocal cloning… please make sure its source human consented to the use. Unauthorized voice cloning sort of defeats the purpose of the FTC challenge, after all, and is grounds for immediate disqualification.

Both Google Maps and Apple Maps are intended to help you get from A to B as efficiently and as safely as possible, and to that end they make use of crowdsourced data on anything that might get in the way of that: Road works, accidents, lane closures, hazards, and speed checks, for example.

We know these apps are smart enough to work out some problems such as traffic congestion on their own, because users will all be slowing down at the same spot. However, it also relies on drivers to report what’s on the road as well, to get a complete picture of what conditions are like.

You can take part in these community reports too, doing your bit to let other users know about problems on the road—these apps don’t just go off one person’s say-so, but if enough reports about something match up, then it’ll be reflected in what you see on the map as you navigate around.

Reporting incidents in Google Maps

You have to be in the navigation mode for Google Maps in order to report something. Tap the icon on the right, that looks like a plus symbol inside a speech bubble: This will bring up the report options. You can get to the same screen by swiping up on the estimated journey time (under the map), to show the Add a report option.

These may vary slightly depending on where in the world you are, but you’ll typically see options such as Crash, Mobile speed camera, Congestion, Roadworks, Lane closure, Stalled vehicle, and Object on road. There are no further options to set, but an Undo button is briefly displayed before the report is logged, if you change your mind.

You can also use your voice to make a report, which is the safer option if you’re driving. Just say “hey Google” and then the report you want to make—”there’s a crash here” for example. As long as your choice of phrasing makes it clear what you want to report, Google Assistant will understand what you mean.

If you’re using Android Auto, at the time of writing, there’s no way to report incidents—either by tapping on the screen or using Google Assistant—so you have to use your phone. It seems a strange omission by Google, but you will still see the incidents and hazards that have been reported by other users on your car’s dashboard.

In Apple Maps on the iPhone, you can report incidents without being in navigation mode (if you’re just walking by, for example): Tap your account picture (next to the search box), then Reports, Report a New Issue, and Report an Incident. If you are in navigation mode, tap the route details underneath the map, then Report an Incident.

The three options are Crash, Hazard, or Speed Check, though they can vary by country. In navigation mode, your report is instantly registered at your current location, but if you’re not using navigation mode then you have the option to specify a location on the map. You can also add some brief written details and even photos to go alongside the report. Tap your account picture on the main maps screen, then Reports to see reports that you’ve previously logged.

All of this can be managed via Siri too, which is also a safer option if your eyes are on the road. Your phrasing doesn’t matter too much, as long as you clearly communicate the gist—”hey Siri, report an accident” or “hey Siri, there’s something in the road” would both be acceptable, for example. If you use Siri, the report is instantly registered.

If you’re using Apple Maps with CarPlay, then you can make use of Siri as described above. If you’re able to use the screen safely, when you’re not navigating, you can also tap on the little blue icon on the left (showing an exclamation mark inside a rectangular speech bubble) to find the report options. If navigation mode is enabled, tap on the route eta box to find the same report options.

This article was originally featured on MIT Press.

There may be nothing unnatural in nature, but nature still encompasses much that seems fantastically strange—the amazingly multifarious sex lives of animals, for example. Emmanuelle Pouydebat’s “Sexus Animalis,” from which the following text is excerpted, tells us everything we never dreamed we wanted to know about the reproductive systems, genital organs, and sexual practices of animals, from elephants (who masturbate with their trunks) to fruit flies (who produce spermatozoa 20 times their size) to bark lice (whose females penetrate the males—see below). In the animal kingdom we find heterosexual, lesbian, gay, and bisexual behavior, as well as monogamy, polygamy, and polyandry, not to mention fellatio and many varieties of erections and orgasms.

Pouydebat, a natural history researcher, tells us about gutter penises, double penises, detachable penises, and corkscrew-shaped penises, as well as vaginas built for storage and clitorises with thorns. (Perhaps unsurprisingly, there’s more data about animal penises than animal vaginas and clitorises.) She explains how the ostrich achieves an erection, describes the courtship of pygmy chameleons, and recounts how the female short-beaked echidna chooses a partner. Indeed, “over the course of this book, human organs and sexuality come to look pretty humdrum,” writes Pouydebat. “The animal world has beat us on every score.”


BARKLICE (neotrogla sp.)

We’ve already seen how females of Nicrophorus vespilloides chemically castrate males to make them monogamous. The barklice of the Neotrogla genus use an even more radical strategy. And you thought it couldn’t be done.

These barklice are tiny flies about three millimeters long. They live in dry caves in Brazil, where they seem to feed on guano and bat carcasses. Nothing very exceptional. But here it comes. This is a unique case (who knows, maybe others will be found) of sexual inversion. That’s right: the genital organs of males and females work the other way around. We know all about males penetrating females, but here the females pierce the males. You couldn’t ask for a more complete sexual revolution.

So what does all this look like? It’s pretty simple: Females have a kind of false penis, known as a gynosome, which enters the male’s body. Is the point to hurt him? Not at all—it’s to get nutrients and sperm! There’s nothing as reliable as doing the job on your own. And in so doing, Ms. Barklouse takes her sweet time: Mating goes on for a period between 40 and 70 hours! That’s what it takes for the female to assume a position on top of the male, insert her gynosome, and let the swollen organ hang there anchored by spines in the male’s genitals. To get an idea, know that her false penis sits so firmly that if you try to unhook her, the male’s abdomen will rip right off. Nutrients obtained by this means are vital for her to conceive eggs. Such behavior might have developed because the caves where these barklice dwell offer scant resources. If so, this is a way of killing two birds with one stone, so to speak. Just consider the males as sperm banks and refrigerators in one. That’s really turning the tables!

Ms. Barklouse takes her sweet time: Mating goes on for a period between 40 and 70 hours!

Is anything like this known to happen elsewhere? When it comes to consuming resources that belong to the male, other examples exist, which are just as spectacular—if not more so. For instance, the female sagebush cricket (Cyphoderris strepitans) eats her partner’s fleshy wings in the process of mating. But the Palme d’Or probably goes to mosquitoes of the Heleidae (Ceratopogonidae) family. When mating, the female simply pierces her partner’s head with the pincers on her mouth. By this means, she can inject digestive juices so that his body will dissolve before she devours it. Incredible. . . . Then she throws away his empty shell, keeping only the genitals (which are now attached to her) for fertilization. It bears repeating: She liquefies her partner, gulps him down, then keeps his stuff for herself. That’s really something else.

DAMSELFLY (Zygoptera sp.)

“Damselfly”. . . . What a pretty little name. It might charming, but it conceals unexpected cruelty. Among many insects, the morphology of the penis is perfectly matched to the internal anatomy of the female’s genitals. Unfortunately, this doesn’t prevent males from expressing themselves to the detriment of their partners. Gentlemen damselflies—like dragonflies, their close relative—exhibit astonishing anatomical particularities.

To appreciate just what is happening, it’s important to understand the act of mating itself. Most of the time, the male straddles the female, and sometimes the female rides on top of the male. But any number of other positions can be assumed in keeping with anatomical constraints. What’s remarkable about damselflies is that they produce sperm at one end of the abdomen, while their copulating organ is located at its base. Hardly a practical design. To remedy the situation, the male, prior to mating, bends his body in order to fill up the reservoir that is part of his reproductive apparatus with sperm. During the act itself, he grabs his partner between his head and thorax by means of the pincer at the end of his abdomenDifficulties don’t stop here, though. The female’s genital opening is at the end of her abdomen, so she needs to bend forward for contact with the penis to work. Damselflies form a heart-shaped figure when mating! That might sound poetic, but things get pretty ugly. . . .

The competition’s tough. When damselflies set about reproducing, a whole gang of males gather at places suitable for laying eggs. Very few of them will manage to mate with a female. What’s more—and as is the case with other arthropods and mollusks—lady damselflies are endowed with a spermatheca and can hook up with several partners, then save the sperm for fertilizing eggs later on. While this might seem like a boon for the female, it poses a danger for males, whose sperm can get crowded out by somebody else’s.

When the female is, ahem, busy, the male is busy scraping out between 90 and 100 percent of the sperm left by his predecessor.

Consequently, male damselflies have a strategy of their own for optimizing the transmission of their genes. Evolution has equipped them with a reproductive organ—the aedeagus, to be technical—that’s shaped like a spoon. That’s right. And the male uses this mighty appendage, a veritable work of art, as a scraper to remove the sperm of his predecessors. Some dragonflies even have thorns, bristles, or other barbs on their organ. So for a few minutes when the female is, ahem, busy, the male is busy scraping out between 90 and 100 percent of the sperm left by his predecessor. Then, in just a few seconds, he makes his own deposit in the sperm bank. Whoever does so last basically gets to be the proud father. Kicking out rival sperm to ensure the greatest chance of fertilization—somebody was bound to do it.

To conclude our discussion of the matter, note that suppressing rival sperm can also occur by chemical means. Some mosquitoes have a substance in their semen that will act to expel sperm that is added later. By the same token, but in reverse, some members of Drosophila have sperm that will drive out what rivals have already left behind.

This article was originally featured in The Conversation.

The year 2023 proved to be an important one for space missions, with NASA’s OSIRIS-REx mission returning a sample from an asteroid and India’s Chandrayaan-3 mission exploring the lunar south pole, and 2024 is shaping up to be another exciting year for space exploration.

Several new missions under NASA’s Artemis plan and Commercial Lunar Payload Services initiative will target the Moon.

The latter half of the year will feature several exciting launches, with the launch of the Martian Moons eXploration mission in September, Europa Clipper and Hera in October and Artemis II and VIPER to the Moon in November–if everything goes as planned.

I’m a planetary scientist, and here are six of the space missions I’m most excited to follow in 2024.

1. Europa Clipper

NASA will launch Europa Clipper, which will explore one of Jupiter’s largest moons, Europa. Europa is slightly smaller than Earth’s Moon, with a surface made of ice. Beneath its icy shell, Europa likely harbors a saltwater ocean, which scientists expect contains over twice as much water as all the oceans here on Earth combined.

With Europa Clipper, scientists want to investigate whether Europa’s ocean could be a suitable habitat for extraterrestrial life.

The mission plans to do this by flying past Europa nearly 50 times to study the moon’s icy shell, its surface’s geology and its subsurface ocean. The mission will also look for active geysers spewing out from Europa.

This mission will change the game for scientists hoping to understand ocean worlds like Europa.

The launch window–the period when the mission could launch and achieve its planned route–opens Oct. 10, 2024, and lasts 21 days. The spacecraft will launch on a SpaceX Falcon Heavy rocket and arrive at the Jupiter system in 2030.

2. Artemis II launch

The Artemis program, named after Apollo’s twin sister in Greek mythology, is NASA’s plan to go back to the Moon. It will send humans to the Moon for the first time since 1972, including the first woman and the first person of color. Artemis also includes plans for a longer-term, sustained presence in space that will prepare NASA for eventually sending people even farther–to Mars.

Artemis II is the first crewed step in this plan, with four astronauts planned to be on board during the 10-day mission.

The mission builds upon Artemis I, which sent an uncrewed capsule into orbit around the Moon in late 2022.

Artemis II will put the astronauts into orbit around the Moon before returning them home. It is currently planned for launch as early as November 2024. But there is a chance it will get pushed back to 2025, depending on whether all the necessary gear, such as spacesuits and oxygen equipment, is ready.

3. VIPER to search for water on the Moon

The VIPER rover to survey water at the south pole of the Moon.

VIPER, which stands for Volatiles Investigating Polar Exploration Rover, is a robot the size of a golf cart that NASA will use to explore the Moon’s south pole in late 2024.

Originally scheduled for launch in 2023, NASA pushed the mission back to complete more tests on the lander system, which Astrobotic, a private company, developed as part of the Commercial Lunar Payload Services program.

This robotic mission is designed to search for volatiles, which are molecules that easily vaporize, like water and carbon dioxide, at lunar temperatures. These materials could provide resources for future human exploration on the Moon.

The VIPER robot will rely on batteries, heat pipes and radiators throughout its 100-day mission, as it navigates everything from the extreme heat of lunar daylight–when temperatures can reach 224 degrees Fahrenheit (107 degrees Celsius)–to the Moon’s frigid shadowed regions that can reach a mind-boggling -400 F (-240 C).

VIPER’s launch and delivery to the lunar surface is scheduled for November 2024.

4. Lunar Trailblazer and PRIME-1 missions

NASA has recently invested in a class of small, low-cost planetary missions called SIMPLEx, which stands for Small, Innovative Missions for PLanetary Exploration. These missions save costs by tagging along on other launches as what is called a rideshare, or secondary payload.

One example is the Lunar Trailblazer. Like VIPER, Lunar Trailblazer will look for water on the Moon.

But while VIPER will land on the Moon’s surface, studying a specific area near the south pole in detail, Lunar Trailblazer will orbit the Moon, measuring the temperature of the surface and mapping out the locations of water molecules across the globe.

Currently, Lunar Trailblazer is on track to be ready by early 2024.

However, because it is a secondary payload, Lunar Trailblazer’s launch timing depends on the primary payload’s launch readiness. The PRIME-1 mission, scheduled for a mid-2024 launch, is Lunar Trailblazer’s ride.

PRIME-1 will drill into the Moon–it’s a test run for the kind of drill that VIPER will use. But its launch date will likely depend on whether earlier launches go on time.

An earlier Commercial Lunar Payload Services mission with the same landing partner was pushed back to February 2024 at the earliest, and further delays could push back PRIME-1 and Lunar Trailblazer.

5. JAXA’s Martian Moon eXploration mission

The JAXA MMX mission concept to study Phobos and Deimos, Mars’ moons.

While Earth’s Moon has many visitors–big and small, robotic and crewed–planned for 2024, Mars’ moons Phobos and Deimos will soon be getting a visitor as well. The Japanese Aerospace Exploration Agency, or JAXA, has a robotic mission in development called the Martian Moon eXploration, or MMX, planned for launch around September 2024.

The mission’s main science objective is to determine the origin of Mars’ moons. Scientists aren’t sure whether Phobos and Deimos are former asteroids that Mars captured into orbit with its gravity or if they formed out of debris that was already in orbit around Mars.

The spacecraft will spend three years around Mars conducting science operations to observe Phobos and Deimos. MMX will also land on Phobos’ surface and collect a sample before returning to Earth.

6. ESA’s Hera mission

Hera is a mission by the European Space Agency to return to the Didymos-Dimorphos asteroid system that NASA’s DART mission visited in 2022.

But DART didn’t just visit these asteroids, it collided with one of them to test a planetary defense technique called “kinetic impact.” DART hit Dimorphos with such force that it actually changed its orbit.

The kinetic impact technique smashes something into an object in order to alter its path. This could prove useful if humanity ever finds a potentially hazardous object on a collision course with Earth and needs to redirect it.

Hera will launch in October 2024, making its way in late 2026 to Didymos and Dimorphos, where it will study physical properties of the asteroids.

This article was originally featured on Knowable Magazine.

Over millions of years, the Earth’s upper layers have performed a dance that has created mountains, volcanoes, continents, ridges and ocean trenches.

Tectonic plates play a key role in this process. These huge, irregular slabs of the Earth’s crust—the solid rock surface where humans live—and the upper part of the underlying mantle “float” on a deeper, warmer layer of the mantle. When two plates meet, sometimes one gives way and ends up sinking little by little into the depths, in a process known as subduction.

If the phenomenon occurs along the entire length of the plate boundary, a line of volcanoes, known as a volcanic arc, forms. There are volcanic arcs in the Andes of South America, Tonga in the South Pacific Ocean, the Aleutian Islands of Alaska, the Philippine Islands and Central America, among others — all of them part of the Pacific Ring of Fire, where earthquakes and volcanoes are common.

The Central American arc is relatively small, just 1,100 kilometers long. But it contains an important variety of different types of magmas, some of which are unique on the planet. It is a “geological paradise” hiding secrets worthy of investigation, says Esteban Gazel, a geochemist at Cornell University in Ithaca, New York. “Central America has a rich combination of conditions that allow the comparison of different natural experiments in magma generation,” he and his two coauthors wrote in a review published in the 2021 Annual Review of Earth and Planetary Sciences.

Central America was born on what used to be an oceanic plate, as a consequence of the subduction of tectonic plates. About 150 million years ago, a slow process began that gradually allowed volcanic islands to grow between the continental masses of northern and southern America. About 3 million years ago, the area now comprising Costa Rica and Panama was finally joined to the north of present-day South America, creating a single landmass from Alaska to Tierra del Fuego.

In the last 11,000 years, 70 volcanoes have been active in this part of the Ring of Fire. Just as volcanoes have created fertile lands where agriculture and cattle-raising have flourished, they have also brought death and displaced populations. In 1902, for example, following a series of earthquakes in the region, the Santa Maria volcano in Guatemala recorded one of the largest and most explosive eruptions of the 20th century. In 1968, an eruption of the Arenal volcano in Costa Rica left 78 dead; and in 2018, the Fuego volcano in Guatemala erupted, killing more than 100.

Gazel carried out his first studies as a geochemist in Costa Rica, his home country. In this interview, edited for length and clarity, he explains how the geology of Central America helps us understand the evolution of our planet.

What is the Central American volcanic arc?

It is an alignment of dozens of volcanoes, not all of which are currently active, stretching from the border between Mexico and northern Guatemala to central Costa Rica. Among them are the volcanoes of Fuego and Tajumulco in Guatemala, Santa Ana in El Salvador, Masaya and Momotombo in Nicaragua, and Arenal and Poás in Costa Rica. This arc is the result of the subduction of the Cocos plate under the Caribbean plate. The Cocos plate is produced in a ridge in the Pacific Ocean. The ridges are submarine fractures through which magma emanates. When magma comes out at a ridge, it pushes the plates, cools, crystallizes and creates new crust.

The Central American volcanic arc is an alignment of dozens of volcanoes stretching from the border between Mexico and northern Guatemala to central Costa Rica. This arc is a product of the subduction of the Cocos plate under the Caribbean plate and generates a variety of different types of magmas, some of them found nowhere else on the planet.

This arc is a product of the subduction of the Cocos plate under the Caribbean plate and generates a variety of different types of magmas, some of them found nowhere else on the planet.

When the plate subducts, it is filled with volatile elements, mainly water and carbon dioxide. At about 60 kilometers deep they become unstable. Because of the high pressure and temperature conditions at those depths, the minerals will break down and the volatiles will come out in a very special form: a hybrid between a liquid and a gas, which is known as a supercritical fluid or a melt. This fluid interacts with the rest of the materials and fuses the rocks of the mantle. This is the process that generates the magma that comes to the surface in the form of lava.

When did this process begin?

We have a history of volcanism in Central America going back many millions of years. The arc has been growing and evolving, creating different versions. It began to form about 150 million years ago, at the time of the dinosaurs.

The tectonic system moves and accommodates itself. For example, the Cocos plate does not have the same subduction angle along the arc’s 1,100 kilometers; the way in which it enters under the Caribbean plate—its entry angle—is different in different areas. This affects the formation of the arc.

When plates converge at subduction zones, the thin, dense oceanic crust sinks beneath the thick, buoyant continental crust. Volcanoes form when the subducting oceanic plate becomes hot enough to melt materials and create magma that rises to the surface as lava.

For example, some 20 million years ago, the arc was where the San Carlos plains are—north of what is now Costa Ric —and to the east of today’s Nicaragua Lake. It resembled today’s Mariana Islands [a group of islands aligned north to south, close to each other and located southeast of Japan]. The arc continued to where Chiapas is today, in Mexico.

Today, the arc is closer to the Pacific coast in northern Central America and toward central Costa Rica. Most of the volcanoes you see today are 500,000 to 250,000 years old. But there are also younger volcanoes. Nicaragua’s Cerro Negro is the youngest, dating from 1867.

The Earth evolves and leaves old versions. The pages of the evolution of the planet are written on these rocks.

What makes the Central American volcanic arc unique?

It is something incredible. The geochemical variations from Nicaragua to Costa Rica are the most extreme on the planet. Throughout Italy there are magmas similar in chemical composition to those of Costa Rica, but all those volcanoes in Italy are going to be very similar to each other.

In the Mariana Trench in the western Pacific Ocean, the magmas are very similar to those of Nicaragua, but all the volcanoes in the Marianas produce magmas very similar to each other.

Italy and the Mariana Trench are separated by thousands of kilometers, while Costa Rica and Nicaragua show important geochemical differences in their magmas even though they are very close. The extreme amount of variation in such a small area makes Central America the only place on the planet with these characteristics, and therefore a unique natural laboratory.

Why is there so much variation?

The regional variation is controlled by the angle of subduction and the composition of the subducted material. The local variations of Central American volcanoes are controlled by the volume of the volcano. Very large volcanoes have more molten material coming from the mantle and less variability. In contrast, smaller volcanoes have much more geochemical variation. Large volumes of magma homogenize the signal, and smaller volumes show us more extremes.

Central America also has a combination of denser oceanic crust and lighter continental crust. What does this mean and what does it teach us?

It is something very unique to Central America. In the Mariana Trench, the whole arc is developed in oceanic crust. In the Andes, in South America, the entire arc develops in continental crust. In Central America, the arc starts in continental crust in Chiapas and Guatemala, and when we enter Costa Rica, we enter the oceanic crust. All the magmas in Costa Rica are oceanic arc magmas that look very much like the Marianas, until about 15 million years ago when things start to change again, and the magmas in Costa Rica start to look more like continental crust. This tells us that this is a very dynamic zone.

Why does this happen?

Fifteen million years ago, a much younger crust began to reach what is now Costa Rica, with the Galapagos seamounts—submerged oceanic islands in the Pacific Ocean that once were like what are now the Galapagos Islands of Ecuador. That is what is known as a hot spot, a thermal anomaly that brings material from the Earth’s lower mantle. These islands travel with the plate, submerge, and eventually collide and enter the Costa Rica-Panama subduction zone, where the Cocos plate dives under the Caribbean plate.

This plate has a unique geochemical signature that shows up in the volcanoes of Costa Rica and Panama. The conclusion from a lot of my work over the years is that Costa Rica was not continental crust, and since about 15 million years ago one of the youngest continental crustal terranes [fragments consisting of a distinct and recognizable series of rock formations that has been transported by plate tectonic processes] on the entire planet has been formed by the melting of these seamounts in the subduction system. So it is also a natural laboratory.

Cocos Island [an island and national park located in the Pacific Ocean, some 500 kilometers off the Costa Rican coast] is part of a series of seamounts. These mountains are entering the subduction zone and are melting. As the crust evolved from oceanic to continental, its density was reduced, allowing Costa Rica and Panama to emerge from the sea. This process contributed to the closure of the Central American isthmus, which finally occurred about 3 million years ago. The birth of the volcanic arc helped to generate sediments in the area, and tectonic activity raised the surface until a complete closure occurred.

So, is Cocos Island getting closer to the mainland?

Yes. In several million years, it will subduct and then come out again as a volcano like Poás or Irazú in central Costa Rica today, where the Galapagos signature is extremely evident.

What are the tools you use to investigate volcanic arcs?

The main tools are the volcanic rocks, obtained after an eruption, because their chemical composition is controlled by these processes. We analyze them using electron microscopes, spectroscopes and mass spectrometry to infer their origin, age and evolution.

How has your field evolved over the years?

I started doing research in volcanology and geochemistry at the Nuclear Research Center of the University of Costa Rica. I started there because geology and volcanology at that time were very descriptive. The nuclear physics researchers implemented more quantitative measurements. When I started my career in the United States, my science evolved to be much more numerical and less descriptive.

In the last decade, and especially the last five years, as a community we have moved to a volcanology that is incredibly precise and quantitative.

That’s only going to continue to expand. We’re already at a point where to be a modern geologist you have to know about geochemistry equipment, about programming, about statistics. Now there is machine learning and artificial intelligence, and all those tools are being used along with field and laboratory data.

Geologically, what does the future hold for this region?

What we must understand is that in Central America we live in a tectonic and volcanically active zone. Prevention and good construction really make a significant difference to save lives in the face of eruptions and earthquakes. Because volcanoes are going to keep erupting and earthquakes are going to keep happening. It is the natural process of evolution.

What new research is coming up?

In January 2024, a group with professionals from different parts of the world will go to Poás volcano in Costa Rica to test new technologies to study volcanic processes and with the goal of someday having a better idea of how to forecast a volcanic eruption. The person organizing it from the United States was my post-doc mentor.

And my lab was just funded by the US National Science Foundation to study Plinian eruptions of mafic composition. Plinian eruptions are the highest-magnitude eruptions, like the Vesuvius eruption that destroyed Pompeii. They are generally felsic, meaning they are high in silica. However, there is a group of mafic eruptions that are high in magnesium and iron that also have that magnitude. In Central America, Nicaragua’s Masaya volcano holds a record for one such eruption.

How can Central America teach us about Earth’s formation more broadly?

If we want to understand how the continents were formed in the early part of the Earth’s evolution, one of the best places to work is Central America.

If we want to study the process of subduction, how it starts and how the composition of continents changes, we have that history in Central America.

If we want to study samples of materials that traveled to the interior of the Earth, that “visited” the mantle in a subduction zone and came up again, they are exposed in Guatemala.

If we want to understand the mechanisms that start very high-intensity eruptions, we have a record of eruptions in Nicaragua and Costa Rica.

So Central America is already a natural laboratory, and it will continue to be a place where many geological processes can be studied.

Additional examples where Costa Rica has something that is very unique are the exposed oceanic crust on the Nicoya Peninsula and the exposed mantle on the Santa Elena Peninsula. In Santa Elena, we have the terrestrial mantle exposed, and you see rocks, known as peridotites, which formed at depths of 50 to 70 kilometers and were brought to the surface by tectonic activity. These are incredibly unique and very interesting sections, which have been the focus of many years of research that have allowed us to better understand the structure, composition and history of the mantle.

Central America will continue to be studied for its diversity: a geological paradise.

Cocktail mainstays are made with CBD to give you a relaxing buzz without any next-day remorse.

Between bottles at family dinner(s) or popping Champagne at New Year’s, it’s hard for someone looking for a little non-alcoholic fun to kick off a year of healthier habits. “Liquid courage” and social lubricant, alcohol tends to be everyone’s favorite coping mechanism during the holiday season and gatherings in general, whether when first introduced to the extended family, dealing with distant relatives you’d rather remain removed, or being surrounded by friends of friends. Hence, the growing popularity of Dry January and the opportunity to learn that there are better, healthier ways to cope. Moderation can improve your mental health, lower blood pressure, and, best of all, prevent a dreaded hangover and related hang-xiety … and maybe an argument or two with strangers. Instead of snagging another lazy, hazy IPA out of the fridge, consider an NA beer or alternative spirit. Even better, the best non-alcoholic drinks are proof of the deliciousness of zero-proof that can be enjoyed as new year’s recompense transitions into sober spring and beyond.

Note: If you have moderate to severe alcohol use disorder, please see a healthcare provider before withdrawing, as it can be quite dangerous to detox at home by yourself.

How we chose the best non-alcoholic drinks

I had my own Dry January journey in 2021, after years of problematic college drinking habits and at-home COVID-19 happy hours. I ended up extending it until the middle of February. Instead of a month of regrets and voicing my displeasure of imposing a personal Prohibition—like some other “low to no” participants—I realized, simply put, that alcohol can be bad and getting drunk is dumb. Now, I am a self-proclaimed “beverage girlie” and lead a damp lifestyle: I don’t keep alcohol in my home but will enjoy a beer after improv. I also won’t shut up about how moderation is great. My partner doesn’t drink at all, so we’re always on the hunt for a bubbly, crisp, cold NA bev to sip on during dinners or concerts.

I’ve also reported on beverages in the past for Gear Patrol and have a fridge stocked with Diet Coke, Limoncello La Croix (the best flavor, fight me), and my favorite NA beers. We also consulted Dry Atlas, a non-alc database, for picks.

The best non-alcoholic beverages: Reviews & Recommendations

Going for an NA beer or alternative spirit is just like a vegetarian or vegan going for a meatless chik’n patty or Impossible Burger: you’re simply enjoying a just-as-tasty substitute for something you don’t want to ingest for personal or health reasons. One of these will level up your seltzer or become your innocuous favorite to enjoy while eating takeout and watching Love Island.

Best NA beer sampler: Athletic Brewing NA beer 

Why it made the cut: This NA beer tastes as nuanced as its boozy counterpart without post-six-pack regrets.

Specs

  • Milliliters: 12 fluid ounces (or 355 ml) per can
  • Spirit, beer, or wine: Beer
  • Alcohol removed or zero alcohol: Alcohol removed
  • Enhancements: N/A

Pros

  • Tasty
  • Gluten-free
  • Made of clean and natural ingredients

Cons

  • Might not be able to be consumed if you’re pregnant

If a fresh, cold one is more your style, Athletic Brewing has your back with its NA brews. They don’t have a bready aftertaste like other NAs; in fact, they are some of the best-tasting NAs you can buy, with the company racking up plenty of awards over the years. This 24-pack can fill the fridge so everyone can crack open one outside without the mood threatening to be cracked when too many full-strength brews make tongues loose.

Best NA stout: Guinness Non-Alcoholic Draught Beer

Guinness

SEE IT

Why it made the cut: An Irish classic gets a non-boozy touch without sacrificing quality.

Specs

  • Milliliters: 14.9 millimeters per can
  • Spirit, beer, or wine: Beer
  • Alcohol removed or zero alcohol: Alcohol removed
  • Enhancements: N/A

Pros

  • Guinness taste without the alcohol
  • Pours like a real Guinness
  • Tasty

Cons

  • Heavy beer
  • Might scare some who are sober because of the realistic taste

NA beer can sometimes taste like carbonated bread instead of a bodied, complete fizzy beverage. That is not the case with Guinness Non-Alcoholic Draught Beer, which tastes like its malty cousin. If you’re sober and in recovery, the realistic taste of NA Guinness might make you feel like you’ve seen an ex walk into a room—ignore this one if that would make you uncomfortable, which is what you would also do when seeing your ex walk into a room. This tasty, dark beverage is a reliable choice (unlike your ex!) if you’re looking for a stout without stout regrets.

Best NA import beer: Peroni Nastro Azzurro 0.0

Amanda Reed

SEE IT

Why it made the cut: Evoke the Amalfi Coast with a light Italian lager that’s refreshing and full-bodied.

Specs

  • Milliliters: 330 ml
  • Spirit, beer, or wine: Beer
  • Alcohol removed or zero alcohol: Alcohol removed
  • Enhancements: N/A

Pros

  • Light and refreshing
  • Full-bodied
  • Tasty

Cons

  • Potentially too-close to comfort beer taste

Sometimes you need a light international beer akin to a Stella or a Heineken. We’re personal fans of Peroni, a light Italian lager that screams “warm summer breeze and riding a Vespa.” However, maybe you’re the person driving the Vespa and can’t imbibe a lovely Peroni? Enter Peroni Nastro Azzurro 0.0, which, for an NA lager, is incredibly full-bodied (read: not watery). It tastes like its Peroni Nastro Azzurro boozy cousin, which might cause you to do a double-take at the label, but for those hoping to hop on a Vespa or behind the wheel of a Fiat, the Nastro Azzurro 0.0 is a solid choice.

Best with CBD: Day One Sparkling Water

Billy Cadden

SEE IT

Why it made the cut: This refreshing, no-cal beverage is infused with CBD to promote relaxation.

Specs

  • Milliliters: 12 fluid ounces (355 milliliters)
  • Spirit, beer, or wine: Canned sparkling water
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: CBD

Pros

  • Infused with 20 milligrams of CBD
  • Comes in grapefruit, lemon, and lime flavors
  • Zero calories
  • Made with natural ingredients

Cons

  • Pricey for sparkling water

Looking for a pick-me-up that doesn’t pack any calories? Consider Day One Sparkling Water. This canned beverage is infused with 20 milligrams of CBD, also known as cannabidiol, a chemical found in the Cannabis sativa plant known for its ability to promote relaxation without getting you high. Day One’s sparkling water is available in grapefruit, lemon, and lime flavors and doesn’t have any sugar or calories.

Best non-alcoholic aperitif: Ghia 

Ghia

SEE IT

Why it made the cut: This twist on a traditional aperitif is tasty and can be consumed on its own or mixed.

Specs

  • Milliliters: 500 ml
  • Spirit, beer, or wine: Aperitif
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: Some adaptogens (lemon balm; rosemary)

Pros

  • Tasty
  • Versatile
  • Makes you feel sophisticated and fancy

Cons

  • Small bottle compared to others on this list

Inspired by Mediterranean aperitivo culture—think Campari and Amaro over finger food before 9 p.m. dinner in a bustling Milanese café—Ghia is light, dry, and the right amount of bitter. Drink it on its own or combine it with a mixer of your choosing for a spritz or cocktail. If a bottle seems like too much of a commitment, check out Ghia’s transportable cans that add lime, salt, and ginger to the OG Ghia aperitif.

If you’re already a Ghia fan and looking for something in the same vein, try Figlia—both have similar ingredients (white grape juice, rosemary extract, and elderflower, for example), but we love this NA aperitif’s earthiness thanks to clove and chamomile extract. Figlia, like Ghia, also sells spritz-in-a-can for on-the-go sips.

Best tequila alternative: Optimist Botanicals Smokey

Billy Cadden

SEE IT

Why it made the cut: A mezcal-like sipper that is smokey and makes for a perfect mocktail margarita.

Specs

  • Milliliters: 500 ml
  • Spirit, beer, or wine: Spirit
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Designed to use mixed like a premium spirit
  • Lots of body
  • Spicy

Cons

  • Not that many fluid ounces compared to others on this list

This botanical spirit has woody, floral, and bitter notes, and is designed to be mixed like a premium spirit. This one specifically drinks like smooth tequila or mezcal. Mix it with your favorite ginger ale and garnish with a jalapeno slice or an orange peel for a scrumptious sipper sans alcohol. However, each bottle is only 16.9 fluid ounces, meaning you’ll have to be cognizant of how much you use before running out.

We also recommend Clean Co.’s CleanT—not only is it a lovely substitute in a margarita or paloma, it pairs lovely with Winderton Lustre (more on that later).

Best gin alternative: Abstinence Spirits Cape Citrus

Jen McCaffery

SEE IT

Why it made the cut: You’ll feel good the next day after drinking this gin alternative, thanks to its lack of alcohol and the company’s dedication to protecting the South African Cape Floral Kingdom.

Specs

  • Milliliters: 750 ml
  • Spirit, beer, or wine: Spirit
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Proceeds go to wildlife conservation
  • No artificial flavors
  • Feels sophisticated

Cons

  • Those looking for an exact gin dupe will be disappointed

Skipping alcohol doesn’t mean you have to skip out on delicious flavor. Abstinence Spirits Cape Citrus is inspired by South Africa’s Floral Kingdom, one of the world’s most diverse habitats. It’s infused with familiar citrus flavors, like orange, grapefruit, and grapefruit along with ginger, fennel, and pepper that give this concoction a subtle savory kick. Other notes, such as the mandarin naartjie and bucchu, are native to South Africa. And with no sugar and zero calories, you can swirl this botanical gin substitute into your seltzer as a pick-me-up any time.

Best whiskey alternative: Ritual

Ritual

SEE IT

Why it made the cut: Have a better boulevardier with this whiskey alternative that’s highly rated by restaurant professionals.

Specs

  • Milliliters: 750 ml
  • Spirit, beer, or wine: Spirit
  • Alcohol or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Heat on the tail end—just like whiskey
  • Rated highly by professionals
  • Soft and round flavor profile

Cons

  • Those looking for a straight whiskey dupe will be disappointed

This whiskey alternative is rated 85/100 Silver by the Beverage Testing Institute, a spirits research & review company. This makes it the highest-reviewed alcohol-free whiskey alternative. The numbers don’t lie! Vanilla and oak overtones mingle with notes of stone fruit and a little kick of heat at the end. Although it’s not meant to be sipped straight, you can use it to make an almost-NA Boulevardier or safer whiskey sour. We’re also fans of NKD LDY’s whiskey alternative, which is smoky and has the whiskey taste without the regret.

Best botanical spirit: Wilderton Botanical Spirit

Wilderton

SEE IT

Why it made the cut: Each flavor is unique and delicious—probably the best we’ve tasted.

Specs

  • Milliliters: 750 ml.
  • Spirit, beer, or wine: Spirit
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Bittersweet Aperitivo a Campari dupe
  • Unique in their own way
  • Versatile

Cons

  • Expensive
  • Not a straight dupe for gin or whiskey

Wilderton’s line of botanicals is a loving homage to spirits like Campari, whiskey, and gin. In fact, their Bittersweet Aperitivo is a spot-on dupe, taste-wise, to Campari or Aperol, making it a great choice if you’d like to make your spritz even lower in ABV. Earthen—with cardamom, white peppercorn, and pine-smoked tea—is rich and spicy and even leaves a bit of heat when you’ve put down your glass and returned to the conversation. Lustre is a dreamy, citrusy blend of bitter orange peel, tarragon, lavender, and coriander that pairs great with tonic or soda water for a crisp mocktail in the garden.

Best value: Dhōs

Tony Ware

SEE IT

Why it made the cut: Refresh your bar with spirits that contain organic ingredients.

Specs

  • Milliliters: 750 ml.
  • Spirit, beer, or wine: Spirit
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Less than $80 for three bottles
  • Made by a well-established distillery
  • The cheapest bottle on this list

Cons

  • Bundle subscription includes all three flavors—a bummer if you’re looking for multiples of the same flavor

Practicing moderation doesn’t mean sacrificing pleasure; distillers don’t have to forego flavor to achieve alcohol alternatives. These are the immediate takeaways after sampling the Dhōs non-alcoholic spirit/liqueur lineup—made in a three-step process using natural pesticide-free ingredients. Cooked up at an organic farm and distillery in Sheridan, Ore.—also home to Ransom Spirits, known for reviving Old Tom Gin and making whiskeys and vermouth—the mindful mixtures come in colorful stopper-topped bottles with small batch silhouettes and make for captivating (and keto-friendly) cocktail counterparts. Gin Free is savory, herbaceous, and refreshing—redolent of juniper and lime backed by a peppery note. It’s warm and spicy upon first sip, almost gingery, but turns cool thanks to a cilantro and peppermint component. Want to transition from gin & tonic to an NA Negroni? Mix Gin Free with Bittersweet, which carries over a hint of mint threaded through a sunset-colored elixir of rhubarb, pithy pink grapefruit, flamed citrus peel, and monk fruit. Or add it to soda water for a friendlier spritz. Orange, meanwhile, presents a melange of blood orange and vanilla with a dash of cayenne and coriander. It’s a great replacement for triple sec in off-dry “margaritas” but makes for a creamy, dreamy mocktail on its own with soda water, tonic, ginger ale, and more. Offered for $10 less than competitors on average, Dhōs is a premium product without a top-shelf price tag.

Best celeb-made non-alcoholic bubbly botanical: De Soi

De Soi

SEE IT

Why it made the cut: Each flavor is fine, fresh, and fierce—this bubbly mocktail has it on lock.

Specs

  • Milliliters: 750 ml
  • Spirit, beer, or wine: Bubbly craft cocktail
  • Alcohol or zero alcohol: Zero alcohol
  • Enhancements: Adaptogens like reishi, ashwagandha, L-theanine

Pros

  • Crisp and carbonated
  • Darn tasty
  • Adaptogenic for a little healthy buzz at the party

Cons

  • Those who hate tart things may not enjoy these mocktails

Katy Perry is known for hits like “Teenage Dream” and “Hot N Cold,” but did you know she is also in the health and wellness biz? Not only is she an investor in apple cider vinegar giant Bragg Live Food Products, but she co-founded De Soi, an adaptogen aperitif company, in 2022. Golden Hour (shown here) is made with maca and L-theanine for relaxation and is great for making mocktail mules and a non-alcoholic spritz. Champignon Dreams is a bitter, earthy reishi and passion flower spirit for negroni or old-fashioned lovers. Purple Lune mixes ashwagandha, tart cherry, and botanicals to give the feel of a nightly glass of red. If bottles aren’t your style, De Soi also sells its three flavors in cans. All flavors have a tart bite—if that’s not your jam, stick to something sweeter.

Best bundle: Seedslip

Seedlip

SEE IT

Why it made the cut: A delicious bundle means you can experiment and explore, all while saving some cash.

Specs

  • Milliliters: 700 ml
  • Spirit, beer, or wine: Spirit
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Allergy-friendly
  • High-quality ingredients
  • Versatile

Cons

  • Expensive

If you’re looking for a bundle package, look no further than this one from Seedlip. It includes Seedlip Grove 43 (a citrusy, ginger, and lemongrass spirit), Seedlip Spice 94 (a waltz between allspice, cardamom, and grapefruit), and Seedlip Garden 108 (an herby promenade of peas, rosemary, and thyme). They are best served with ginger ale and a citrus peel garnish—perfect for breaking out the fancy glasses sans next-day guilt.

Best mood lifter: Crisp & Crude

Crisp & Crude

SEE IT

Why it made the cut: These keto-friendly, gluten-free mocktails are infused with terpenes and safe to drink while pregnant.

Specs

  • Milliliters: 8.45 fluid ounces per can (250 milliliters)
  • Spirit, beer, or wine: Canned cocktail
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: Botanical terpenes

Pros

  • Tasty
  • Dietary friendly
  • Pre-mixed

Cons

  • Expensive
  • Only available in cans

These NA craft cocktails are made with botanical terpenes extracted from plants, fruits, and roots for calmness, creativity, and relaxation. You can purchase each flavor individually, but we’re fans of the variety pack that includes four cans of its three flavors: Paloma Daydream (a salty, woody grapefruit drink with Space Queen terpenes); Gold Fashioned (bitter orange, zesty dandelion, and Chocolate Thai terpenes); and Mellow Mule (ginger, citrus, and mint with Pineapple Express terpenes). Leave the joint at home and pass around a can of this instead.

Best canned alternative cocktails: Flyers Cocktails 

Flyers

SEE IT

Why it made the cut: These canned mocktails are inspired by bar favorites and feel just as fancy to imbibe.

Specs

  • Milliliters: 237 ml or 8 fluid ounces
  • Spirit, beer, or wine: Canned cocktail
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: 20 milligrams of CBD

Pros

  • Pre-mixed
  • Cocktail-inspired
  • Feels fancy

Cons

  • Only available in cans, which are small

These sparkling, non-alcoholic drinks are made with 20 milligrams of CBD and are inspired by cocktail menu mainstays. BKLN Gold is reminiscent of an American Bourbon cocktail thanks to its oakiness, spice, and smooth vanilla. Tokyo Marg is a citrusy Yuzu sparkler with a touch of heat. Our favorite, however, is the Sydney Spritz Highball: a bold, herbaceous blend of citrus zest, mandarin orange, and bitters.

Best bottled mocktails: DRY Botanical Bubbly Reserve

Amanda Reed

SEE IT

Why it made the cut: A fizzy mocktail is a screwcap undoing away with DRY Botanical Bubbly Reserve.

Specs

  • Milliliters: 750 ml bottle
  • Spirit, beer, or wine: N/A
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Tasty
  • Zero-effort
  • Good for those with dietary needs

Cons

  • Could use some more carbonation

If you’re looking for a not-so-stiff drink after work but don’t have the brainpower to create something new, take the guesswork out of mixology with these pre-mixed mocktails from DRY. They come in three flavors: Lavender 75, a botanical boozeless take on a French 75; Rose Soleil, a Provence Rose-style beverage with touches of strawberry, rose, and oak; and Spiced Pear, which blends ripe pears with vanilla and cardamom. We also love the company’s line of sparkling water that makes for a great mixer. Although the Botanical Bubbly Reserve flavors could use some more carbonation, they taste like a craft concoction you would find at the bar without the craft concoction price.

Best NA wine: Surely Non-Alcoholic Sparkling Rose

Surely

SEE IT

Why it made the cut: Get all the wine taste without the next-day regrets from drinking the entire bottle.

Specs

  • Milliliters: 750 ml
  • Spirit, beer, or wine: Wine
  • Alcohol removed or zero alcohol: Alcohol removed
  • Enhancements: N/A

Pros

  • Delicate body
  • Friendly to specialty diets
  • Great dupe

Cons

  • Pregnant people may not be able to drink it due to low alcohol content

Some NA wines include fruit juice, but if you’re looking for something that screams more wine glass and less Welch’s, Surely’s line of dealcoholized wines is for you. It’s aged in the barrel just like its boozy counterpart, but then the alcohol is removed. The final product is a dry, full-bodied sparkling rose that pairs well with seafood and dessert—just like what someone would find at a liquor store. Coupe glasses sadly not included.

In case you’re looking to expand your NA wine palate, we also are fans of Joyus. For those looking for something that’s on the floral side, look no further than Starla’s NA sparkling rose.

Best wine alternative: Proxies

Proxies

SEE IT

Why it made the cut: As the name implies, Proxies is an homage to the wine experience while setting itself apart from its boozy cousin.

Specs

  • Milliliters: 750 ml
  • Spirit, beer, or wine: Wine
  • Alcohol removed or zero alcohol: Zero alcohol
  • Enhancements: N/A

Pros

  • Tasty
  • Has a similar look and mouthfeel to alcoholized wines
  • Safe for pregnant people to drink

Cons

  • Some flavors can come off as too juice-like

Wine alternatives tend to taste like fancy grape juice. Although that’s not a bad thing, sometimes it’s more enjoyable to drink something that tastes like it came from Napa Valley and not from a toddler’s sippy cup. Proxies—vinegar giant Acid League’s wine alternative brand—uses wine grapes, tea, vinegars, and other fruit for its enchanting wine-inspired blends. Blanc Slate is reminiscent of a Sauvignon Blanc, and Red Ember is all body without the bite. Red Clay is probably the most “wine-like,” with its velvety mouthfeel and lingering pucker.

What to consider when buying the best non-alcoholic beverages

Non-alcoholic beverages are a great way to get the ritual feel of making a cocktail or pouring a glass of wine sans alcohol. You can find them online or at your local liquor store—in my experience, NA beers have their small section in the beer aisle; NA wines are housed by the bartending accessory or mixer section. If you’re lucky, you might have an NA bottleshop in your neighborhood—like Spirited Away in NYC and The Open Road in Pittsburgh—that you can peruse IRL or that offers to ship and delivers right to your door. Here’s what you should know before making your pick.

NA vs. alternative spirit

NA is short for non-alcoholic. Most beverages with the NA moniker—like beer, wine, and liquor—are made like their alcoholic counterparts. However, they don’t ferment or go through a process that removes the alcohol from a finished, alcoholic product. The result is a beverage with less than .5% alcohol by volume (ABV), which can be labeled as “non-alcoholic” per the FDA. According to the FDA, those who are pregnant should go for a truly zero-alcohol beer or spirit to prevent birth defects, according to the American College of Obstetrics and Gynecology (ACOG).

This is where alternative spirits come in. They are made of herbs, vinegars, juices, and more to give off the vibe of a standard alcoholic spirit. An alternative wine will not taste exactly like Cabernet Sauvignon, but it will offer a similar mouthfeel and body. A botanical gin-like spirit will include juniper or pine to replicate the notes of its alcohol-included cousin.

Adaptogens, nootropics, and CBD

If you’d like a little extra jazz in your drink, consider ones with adaptogens or CBD. Adaptogens like ashwagandha and L-theanine are used in herbal medicine to help the body return to homeostasis, or the body’s state of natural balance. The science is a bit nebulous, so don’t expect them to fix your problems. Nootropics have a similar effect as adaptogens: they claim to boost mood and improve cognition but are scientifically hazy.

Animal studies, self-reports, and research in people suggest that CBD, or cannabidiol, can help with anxiety, insomnia, and chronic pain without the “high” from THC. If you’re looking for something to sip on to unwind after a long day, a CBD-infused beverage is perfect—just make sure it’s coming from a reputable source that posts third-party lab results on their site.

Storage

Unlike your typical bar cart, you’ll need to refrigerate most—if not all—non-alcoholic spirits since they don’t have the high-alcohol content to keep them shelf-stable. If you don’t have the refrigerator space for your bounty of friendly spirits, consider one of the best beverage coolers.

Mixers

You have your spirits and such to make a mocktail—but where do you start? Of course, you can always go for the classic tonic or soda water touch, but the world is your oyster when it comes to mixers. Try Tangerine La Croix with Abstinence Spirits’ Cape Citrus for a citrusy play on a gin soda; Blood Orange Carrot Ginger-flavored Health-Ade Kombucha mixes great with Wilderton’s Lustre; and doesn’t Waterloo’s blackberry lemonade seltzer sound heavenly with Ritual’s alternative whiskey? You can even opt for a pre-made drink mix—espresso martinis, anyone?

Safety

There are only two substances that you can die from unsafe withdrawal: barbituates and alcohol. Quitting cold turkey is OK if you or someone you know does not struggle with alcohol use disorder. Otherwise, supervised alcohol withdrawal is the safest since alcohol withdrawal can lead to seizures, delirium tremens, and death if untreated or improperly executed. Also, consult with a doctor before stopping use—they can help decide if you or someone you know should complete your withdrawal in an inpatient or outpatient setting.

FAQs

Q: How much do the best non-alcoholic drinks cost?

The best non-alcoholic drinks can cost between $3-$200, depending on whether you’re purchasing a single can, a pack of four, a bottle, or a bevy of bottles. Of course, the higher end is mostly bundles of bottles. A single bottle ranges from $8-$30—in our experience, it’s worth grabbing the $20 bottle online versus over the $8 in the liquor store. And, packs of cans will also run you around $20-$30.

Q: Does non-alcoholic beer have alcohol in it?

Yes, but only a small amount. According to the FDA, for a beer to be advertised as “non-alcoholic,” it must have less than .5% ABV in each can. Although zero-alcohol beers exist—like Heineken 0.0—the amount of alcohol in a non-alcoholic beer is insignificant to most people who are sober-curious, live a damp lifestyle, or are in recovery.

Q: Can you drink non-alcoholic beer while pregnant?

The risk in drinking a beer under .5% is low, but no guarantees. Since there is no known safe level of alcohol intake in pregnancy, the American College of Obstetricians and Gynaecologists (ACOG) advises pregnant people not to drink any alcohol while pregnant—including NA drinks and spirits. Talk to your doctor before cracking open an NA beer or alcohol-removed wine and spirits if you’re pregnant.

Final thoughts on the best non-alcoholic drinks

Non-alcoholic beverages—including NA beer and wine, wine alternatives, botanical spirits, and more—are a great way to moderate your drinking during Dry January and beyond. Abstaining from drinking completely, cracking open a euphoric seltzer after drinking a Manhattan, or sticking to a mocktail during a pregame can help you re-evaluate your drinking habits. And let’s be real: the best non-alcoholic drinks are just plain tasty. Plus, your sober friends—weary from having soda, seltzers, and plain water as the only option at restaurants or functions—will appreciate that you have fun, craft non-alcoholic options available at your next backyard shindig.

Solid sounds and pads, with expandability for a low price.

Whether you’re a beginning drummer armed with little more than a fancy for rhythm and a fantasy of rocking a big stage or you’re an active drummer needing some extra sounds and inspiration, electronic drum pads deliver big gifts in a small package. They let you simulate the effect of playing an entire drum kit on a single portable unit, often with hundreds of amazing electronic and acoustic drum, percussion, and melodic sounds. Electronic drum pads let you practice your skills in a small space or add some huge electronic flare to an acoustic drum set. Most of them also easily integrate with computer music production software over USB. Performance drum set add-ons, standalone mini kits, or both: These are the best electronic drum pads. 

How we chose the best electronic drum pads

To select the best electronic drum pads of 2024, we scoured every option, from budget-priced to the highest-end pro options and from the biggest names in the industry to smaller boutique brands. Electronic drum pad users range from beginners to professionals, each with varying needs like at-home practice, in-studio production, and on-stage performance. These picks include great options for each use case, and many of them would work well for all three.

I have firsthand experience with many of these picks—as well as others that did not make the list—from decades of playing electronic drums and pads. Where personal experience was not a factor, we took the advisement of bandmates and other musicians, professional product reviews, online specs and videos, and user feedback. 

The best electric drum pads: Reviews & Recommendations

Electronic drum pad units vary widely, from those including a single pad to ones with 10 or more pads, from those including just a handful of onboard sounds to ones with thousands. Some are made more with practice in mind, while others excel in professional recording and performance. The chosen e-drum pads here cover all the ground when it comes to size, features, and budget. They all have sounds included and a headphone jack (by listening through headphones, you won’t have to spend big money on soundproofing a home studio), so they’re plug-and-play. They also all have either included foot pedals for kick drum and hi-hat or trigger connections for adding foot pedals sold separately.  

Best overall: Roland SPD-SX Pro

Roland

Specs

  • Pad configuration: 9 pads in 3 x 3 rows of square pads and edge pads
  • Number of sounds/storage: 1550+ sounds and 200 kits, w/32GB of audio storage
  • Connectivity: 1 x 1/4-inch audio input, 1 x 1/4 headphone output, 2 x 1/4-inch main audio outputs, 4 x 1/4-inch audio outputs, 6 x 1/4-inch trigger/footswitch inputs, 5-pin MIDI I/O, USB-A for storage, USB-B for computer 

Pros

  • Huge selection and variety of sounds, kits, and effects
  • Outstanding build quality and pad response
  • Most flexible options on the market for pro drummers
  • Pro level, but also easy to use for beginners
  • Tons of audio connections and trigger ports for expanding into a mini kit
  • Original sample recording and editing

Cons

  • Extras and pro performance features come at a cost.

With the Roland SPD-SX Pro, pro/semi-pro drummers and even dedicated beginners will gain from Roland’s decades of experience making some of the finest electronic multi-pads in the industry, including the original SPD that originated over 20 years ago. The SPD-SX Pro includes everything that the popular (and still available) SPD-SX had but adds twice the audio storage (32 GB), twice the programmable kits, more audio and trigger connectivity, a 4-inch color display, programmable multi-color pad LEDs, and many new professional performance features. 

For those who just want to plug and play, the SPD-SX Pro furnishes them with more than 1,550 acoustic, electronic, and melodic drum and percussion sounds, as well as 200 preset kits and effects like EQ, reverb, delay, distortion, and compression. Hands-on knobs control volume for main and headphone output and the click (metronome), as well as easy edit knobs for the volume, pitch, and attack/release length of individual sounds. The large display makes in-depth editing of sounds, kits, effects, and audio routing easier, but Roland also includes a dedicated PC/Mac software app for making editing a breeze from a computer connected over USB. Most electronic drum pads don’t include such software. 

The quality and variety of the sounds and the road-worthy build quality are all excellent, yet the myriad options under the hood distinguish the SPD-SX Pro the most. A large basket of performance features lets drummers assign a sequence of sounds to play continuously from a single pad, program color LED effects, create loops, layer different sounds to the same pad, create a set list of kits, switch sounds by velocity (how hard the pad is hit), link pads together, create pad mute groups, and more. The unit can also record samples from the audio input or load and edit samples imported from the USB drive input. 

All told, the Roland SPD-SX Pro offers comprehensive and high-level features whether you want a simple set of drum pads to play or a complex live performance powerhouse that can run backing tracks and send different sounds through different audio outputs. With all its trigger and pedal connections, you could expand it into its own mini e-drum kit with optional kick and high-hit pedals and extra drum and cymbal pads. Although the SPD-SX Pro’s price dwarfs that of some full electronic drum kits, you get what you pay for. 

Best value: ddrum Nio

ddrum

Specs

  • Pad configuration: 9 pads in 3 x 3 rows of square pads and edge pads
  • Number of sounds/storage: 608 sounds and 30 kits, w/512MB of audio storage
  • Connectivity: 1 x 1/8-inch audio input, 1 x 1/4 headphone output, 2 x 1/4-inch main audio outputs, 2 x 1/4-inch dual-trigger inputs, 2 x 1/4-inch footswitch inputs, 5-pin MIDI I/O, USB-A for storage drives, USB-B for computer

Pros

  • Diverse selection of high-quality sounds and kits
  • Loads of connectivity options
  • Ability to load your own samples over USB
  • Easy operation

Cons

  • Limited drum sound editing
  • No sample recording
  • Pads not quite as responsive as some higher-priced alternatives

The classic 3-row, 9-pad layout of electronic drum pads has made an indelible impression on drummers’ minds since the success of Roland’s SPD series. This format puts enough pads to simulate a full drum kit within a space that fits well on a desktop or on a stand when incorporated into a larger acoustic or electronic drum set—usually with a ton of great sounds and connectivity/expansion options as well. However, not everyone really needs the comprehensive professional options that drive up the cost of something like the Roland SPD-SX Pro. To grab a great 9-pad electronic drum multi-pad with all the essential basics and many pro-level options without every single pro performance feature, the ddrum Nio makes for an excellent value. 

The Nio contains hundreds of sweet-sounding drum and percussion hits in 30 kits that weigh heavily on acoustic drum kits but also include several nice electronic drum kit styles (trap, drum-n-bass, hip-hop, and more) and percussion kits like Cajon, African, conga, and others. Its decent-sized display and hardware controls make it relatively painless to create your own kits with the onboard sounds or samples imported from a USB drive, and sounds can be edited with 3-band EQ, reverb, and compressor/limiter. 

While the Nio does not include onboard sample recording or waveform editing of the drum sounds, it delivers big time with its connectivity options. Two dual triggers and two footswitch inputs let you build out a larger kit with optional pedals and external triggers. The 5-pin MIDI I/O and USB connections let you integrate the Nio to trigger sounds and sync tempos with computer and MIDI hardware setups. There are also separate headphone and main audio outputs and an 1/8-inch audio input for piping in your own songs or tutorial lessons to play along to. Other helpful practice features include a loop recorder and metronome. 

The Nio’s pads are not quite as responsive as some high-end multi-pads, but they are very powerfully built, and the whole unit is sturdy and ready for live performance. For its reasonable price, the Nio should make a very capable electronic drumming companion for years to come. 

Best for beginners: Yamaha DD-75

Yamaha

SEE IT

Specs

  • Pad configuration: 8 pads arranged like a drum set and 2-foot pedals for kick and hi-hat
  • Number of sounds/storage: 570 sounds and 75 kits 
  • Connectivity: 1 x 1/8-inch aux input; 1 x 1/4-inch TRS output; 2 x 1/4-inch pedal inputs; 5-pin MIDI I/O

Pros

  • Can play with both sticks and hands
  • Many sounds come from Yamaha’s pro gear
  • Battery power and built-in speakers for portability
  • Two included foot pedals

Cons

  • No USB
  • Could use lesson modes other than play-along songs

Many electronic drum pads have trigger ports for connecting kick drum and hi-hat pedals sold separately, as well as audio outputs for hooking up to an amplifier or powered monitors. However, for a beginning drummer, the Yamaha DD-75 offers built-in speakers (as well as an audio output for headphones or speakers) and two foot pedals for controlling the bass drum and hi-hat sounds. Also, its portability makes it one of the best electronic drum sets for beginners—it can run on either the included AC adapter or six C batteries, making the DD-75 a portable mini-kit of electronic drum pads right out of the box. 

Some internal songs allow drummers to play along to practice their timing, but there’s also an internal click track to practice to and an audio input for plugging in any music to play along to through the speakers or headphones. An internal 4-track recorder also makes it fun to try to layer together music from the DD-75’s selection of world percussion, acoustic, and electronic drum sounds that were made originally for high-end Yamaha synthesizers and electronic drum kits. The pads are also made to respond well to playing them either with the included sticks or your hands. 

Although an all-in-one wonder for just a few hundred dollars, the DD-75 does also have 5-pin MIDI input and output, meaning you can trigger its sounds from another MIDI keyboard or use the DD-75’s pads to trigger sounds from other MIDI sound modules. However, the DD-75 does not have USB for integrating into computer music setups. But the DD-75 portable electronic drum pads have everything needed to keep a beginning drummer happy or for an experienced drummer’s at-home compact practice kit. 

Best compact: Alesis SamplePad 4

Alesis

SEE IT

Specs

  • Pad configuration: 4 pads (2 large, 2 edge)
  • Number of sounds/storage: 25 sounds and 10 kits, w/expansion storage via SD card slot (up to 32GB) 
  • Connectivity: 1 x 1/4-inch stereo headphone out, 2 x 1/4-inch main audio out, 1 x 1/4-inch TRS dual trigger input, USB-B for MIDI I/O, SD card drive

Pros

  • Compact and light, yet capable
  • SD card can add hundreds of sounds
  • Reasonably priced

Cons

  • USB is for MIDI transfer only, not audio
  • Only 25 onboard sounds

Sometimes, a practice space, bedroom, garage, etc., doesn’t have a lot of extra space, but a single trigger pad like the Roland SPD::One just won’t do. In that case, the compact Alesis SamplePad 4 steps in. At 7.5 x 10.25 inches and 2.5 pounds, it’s less than half the footprint and weight of the Roland SPD-SX Pro and other similar electronic drum multi-pads. Within that space are four pads for triggering the 25 high-quality onboard sounds. While that’s not many sounds, the SD card drive (memory card not included) can load up to 512 samples and 89 user-created kits from an SD card. 

The SamplePad 4 can edit both onboard and SD card sounds by adjusting their tuning and adding reverb. It can also set individual audio level and panning (stereo left/right) settings for each sound. For expansion, the SamplePad 4 can accept up to two additional external trigger pads or pedals through its dual trigger input. Also, the USB port sends MIDI data (although not audio) to a computer, so you can use the SamplePad 4 to record realistic-sounding beats in digital audio workstation (DAW) software

Small, yet expandable, the SamplePad 4 fits into nearly any setup, and its low price fits into tight budgets as well. 

Best set: Roland TD-02K

Roland

SEE IT

Specs

  • Pad configuration: 4 drum pads, 3 cymbal pads, 2 foot pedals
  • Number of sounds/storage: 16 unique kits 
  • Connectivity: 1 x 1/8-inch aux input; 1 x 1/8-inch stereo output, USB Type-B for MIDI and stereo audio

Pros

  • Good quality full e-drum kit with compact footprint
  • Dual-zone cymbal pads with choking feature 
  • Built-in Coach mode practice exercises
  • USB port transmits both MIDI and audio

Cons

  • Foot controller for the kick rather than a pedal with pad
  • Rack stand system not very flexible for arranging pads’ position

Most of the electronic drum pads listed here have expansion trigger ports for adding kick or hi-hat pedals or external drum or cymbal pads. That lets you expand them into a compact mini-kit. However, if a full kit is what you’re after in a set of electronic drum pads, you could have that in one go with something like the Roland TD-02K, a full e-drum kit that gives you the acclaimed sound and build quality of Roland V-Drums in an affordable package—foot pedals and cymbal pads included. 

The TD-02K sets up conveniently in a small corner space on a metal rack stand and includes the TD-02 drum module, which has 16 kits spanning huge-sounding studio drums, tight and dry kits, and modern electronic drums based on recent chart-toppers. The module has an audio input for playing along to songs or tutorial videos and a USB port for connecting to a computer and recording both the MIDI data and audio output of the TD-02K module.  

All four of the kit’s drum pads have refined rubber surfaces, and the two dual-zone crash cymbals also have a choking function, where you can mute a cymbal crash sound by grabbing the cymbal pad with your hand. Rather than rubber pads, many more expensive electronic drum kits use mesh heads for their drums, which more closely mimic the feel of acoustic drum heads. Roland offers a version of this kit, the TD-02KV, which is exactly like the TD-02K except it has a dual-zone mesh-head V-drum snare with adjustable tension and rim trigger for $200 more. Each version of the kit is small and sturdy enough to be picked up and moved after a practice session, making it ideal for fitting a full electronic drum pads kit into a small or crowded space. 

The TD-02 module encourages practicing and steady improvement with its built-in Coach mode that dishes out lessons like Time Check, Change-Up, Quiet Count, Auto Up/Down, and more. The module also has a special slot in the back for an optional Boss Bluetooth Audio MIDI adapter, which gives the TD-02 Bluetooth connectivity for audio and MIDI when purchased separately.

Best budget: KAT Percussion KTMP1

Kat Percussion

SEE IT

Specs

  • Pad configuration: 4 
  • Number of sounds/storage: 50 drum and percussion sounds 
  • Connectivity: HDMI 2.1 input x3, HDMI 2.1 eARC output x1, optical digital

Pros

  • Low price and small footprint
  • MIDI out and USB for incorporating into larger setups
  • Kick and hi-hat trigger inputs for expansion
  • Well built for its cost

Cons

  • No preset or savable kits
  • Pads are less responsive than more expensive options

If budget is your chief concern when shopping for electronic drum pads, there are many low-priced—and shoddily made—options you could find online that we don’t recommend you buy. What good is “saving” money if your purchase doesn’t work in a month? Instead of falling for the promises of lousy gear that will soon end up in a landfill, consider an option that, while not perfect, is made to last and offers a complement of high-level features: the KAT Percussion KTMP1. 

For about a hundred dollars, the KTMP1 provides 50 diverse drum and percussion sounds and four pads in a circular arrangement that doesn’t take up much more surface area than a non-electronic practice pad. The sounds range from acoustic and electronic bass drums, snares, toms, cymbals, and percussion sounds like tambourine, cowbell, conga, tabla, and more. Unfortunately, there are no kits to scroll through, but you can select any sound you want for each pad with the hardware buttons and basic two-digit display. 

The KTMP1 also integrates nicely into larger setups with a MIDI out and USB connection for playing sounds from other MIDI modules or virtual instruments and samples from computer software. Two trigger jacks for a hi-hat controller and kick drum pedal—such as the KAT KT-HC1, KAT KT-KP1, or other third-party options—let you expand the pads into a mini drum set. The KTMP1 does not have that many onboard sounds, but the simple menu does allow you to set the tuning, panning, level, and reverb amount for each sound. In the end, the KTMP1 presents an affordable electronic drum pad option with enough capability to be useful for practice, performance, and music production. 

What to consider when shopping for the best electronic drum pads

There are many factors to weigh when deciding which electronic drum pads are best for you. Below are the ones we considered most important when making our recommendations:

Goals, skill level, and/or commitment

Some people are basically born to drum, and others have an interest in drumming but don’t believe they could ever do it. Electronic drum pads can be a good avenue to explore an interest in drumming without committing a huge amount of money and room in your living space. You can use them to practice along to video lessons or your favorite songs and then find out if you want to take the practice further with a larger drum kit or with additional trigger pads, cymbal pads, and pedals that plug into your electronic drum pads.

Your plans to just practice at home for fun or to use your electronic drum pads to perform live, either solo or in a band, can inform you of the level of features and options you need. Most electronic drum pads can connect to a computer and include some software and/or can add kick and hi-hat pedals plus other triggers to build an electronic drum pad unit into a formidable practice or performance kit. 

Other high-level features that more casual users could probably do without include the ability to record samples from external audio or microphone inputs, high-level sound editing, and sound effects. The most professionally equipped electronic drum pads may include specialized live performance features meant for triggering a band’s backing tracks from the pads, creating set lists of drum kits for quick switching between songs, and so on. Weighing your current needs against your future goals for using your electronic drum pads will inform how sophisticated a unit will be best for you.

Budget

The electronic drum pads listed here range from about $100 to $1,100, and that price range represents a range in build quality, onboard sounds, connectivity, internal menu options, and more. You won’t always be able to satisfy any budget if you have the highest demands for an electronic drum pads unit. However, there are usually at least some options. For example, the closest thing to the comprehensive capability of the Roland SPD-SX Pro is probably the Alesis Strike Multipad, which approximates much of the capabilities at a significantly lower price. 

When figuring out your budget, remember that if you don’t have them already, you may need drum sticks, a stand for the electronic drum pads, plus expansion foot pedals and trigger pads if you want them. Those extras could easily add another few hundred dollars to your total. 

Will it be part of a larger drum set or a standalone?

Many drummers like to add an electronic drum pad to their acoustic kit as a way of incorporating a wide variety of additional sounds to their setup without having to add a large amount of extra gear. If that’s the case for you, any of the options in this guide could work for you, and it just depends on how many pads and sounds you want. Or you may want to look at the popular Roland SPD-One series, which are super-compact single pads with tank-like build quality (such as the SPD-1P percussion pad). They cost a fair amount for a single pad, but they are made for the rigors of the road.

If, on the other hand, you want your electronic drum pads to serve as a standalone unit for playing like they’re a full drum kit, the Yamaha DD-75 is a very self-contained unit that includes its own foot pedals. Many other electronic drum pads can be expanded into mini drum kits by adding foot pedals and additional trigger pads or cymbals. The units with most connectivity for expansion are usually the 9-pad multi-pads like the Roland SPD-SX Pro and ddrum Nio. But even the small, budget options like the KAT Percussion KTMP1 have connectors for optional kick drum and hi-hat triggers.

Will you use it to record and produce music? 

If you plan to or think you may use your electronic drum pads for recording music into computer software or integrating them into a larger hardware MIDI setup, you’ll want a unit with 5-pin MIDI connections and/or a USB port for a computer. 

The USB ports allow you to connect the electronic drum pads to computer software to play sounds from virtual instruments and record beats as MIDI notes from those instruments. Some but not all of the USB connections will also let you record the audio output of the electronic drum pads, so you can record yourself playing beats from the onboard sounds. If that’s something you want, check before buying that the USB port transmits audio, not just MIDI. 

FAQs

Q: Do electronic drums sound like real drums?

Electronic drums can sound like real drums because most electronic drums derive their sounds from samples—short recordings of acoustic drums. (A few electronic drum pads like the Nord Modeling Percussion Synthesizer produce drum sounds from synthesis rather than samples and don’t sound like real acoustic drums, offering alternatives for sound design.) Older electronic drums had very low recording quality for their samples, so they did not sound very realistic. However, today’s electronic drum pads and kits generally use very high-resolution, high-quality samples, and many of them use multiple sample layers per pad so that the sound adjusts to how hard you hit the pad.

Sample-based electronic drum pads and kits won’t sound exactly like real acoustic drums, but they get very close. 

Q: What is a good-sized drum practice pad?

A good-sized drum practice pad approximates the average size of the most commonly hit acoustic drum, the snare drum. The most common sizes of snare drums are 14 and 8 inches in diameter. However, for a practice pad, 10 inches is plenty. Electronic drum pads are often even smaller than that, which can also be good for practice to enforce the good habit of hitting a drum pad or drum head very close to the same place every time (in order to get a consistent sound). You could combine a drum practice pad with an electronic drum pad using the Keith McMillen BopPad, a 10-inch drum pad that connects over USB-C to a computer or mobile device to trigger sounds. The BopPad can play a single sound from the entire pad or be split into four zones to trigger different sounds. 

Q: Do professionals use electronic drums?

Yes, professional drummers use electronic drum kits, as well as electronic drum pads. Actually, professionals use electronic drum pads like the Roland SPD-SX Pro as a supplement to their acoustic drums much more often than they use electronic drum kits onstage. However, superstar music producer (Nirvana, Smashing Pumpkins, Foo Fighters) and drummer garbage Butch Vig says that playing electronic drums live can help to keep the sound pure and make it easier to control the drums’ dynamics. 

So whether you play a full electronic drum kit or use a smaller unit of electronic drum pads to complement acoustic drums, know that you are in good company among professional drummers. 

Final thoughts on the best electronic drum pads

All of these electronic drum pads would make wonderful additions to a music studio or a performing drummer’s hybrid acoustic/electronic rig, and they could all be suitable as entry points to drumming for a beginner. However, purchasing one without fully weighing the options against your personal needs could lead to buyer’s remorse. 

To avoid that, consider how many pads and internal sounds you want and whether you need USB connectivity for MIDI and/or audio. If you want to play the pad unit with your feet as well, make sure it has either included foot pedals (Yamaha DD-75 or the full Roland TD-02K kit) or enough trigger connections to add a kick drum and hi-hat pedal, such as the ddrum Nio. Finally, if you need high-level options like the ability to record your own samples and make performance set lists of drum kits, you’ll probably have to shell out for one of the more expensive high-end options like the Roland SPD-SX Pro.

Before Microsoft released MS-DOS, there was 86-DOS. Now version 0.1 is online thanks to a hobbyist’s archival work.

Although long-abandoned for far more advanced successors, MS-DOS remains a pivotal piece of computer history. Released to the public on the very first IBM Personal Computers back in 1980, MS-DOS quickly became a standard operating system within the growing PC market throughout the ensuing decade. While many versions are still preserved on their original floppy disks, a new archival discovery appears to be the influential program’s earliest known forerunner still in existence.

As recently spotted by The Register and Ars Technica, “vintage code enthusiast” and flight simulator designer Gene Buckle recently unearthed a 86-DOS version 0.1-C floppy disk, reportedly the operating system’s oldest known, still accessible iteration—one that predates even the earliest public version of MS-DOS.

[Related: Yes, the Pentagon still uses floppy disks for nuclear launches.]

Contrary to what many may think, MS-DOS wasn’t actually the creation of Microsoft—the then-newcomers licensed the disk system from a company called Seattle Computer Products (SCP) in 1981. Before Microsoft’s “MS-DOS” rebrand, SCP first called their OS “Quick’n’Dirty Operating System” (QDOS), but soon swapped over to the more marketable 86-DOS name. It’s this earliest version, stored across 9 files, that Buckle found late last month while archiving a backlog of over 400 8-inch floppy disks gifted to him a few years ago.

Interestingly, Buckle already made history earlier that very same day—by finding a copy of 86-DOS version 0.34. For a few hours, this disk was the oldest known MS-DOS precursor… until the subsequent 0.1-C find. Finding a working copy 0.1-C is akin to stumbling across a “holy grail” of computer history, one commenter claims on the Internet Archive entry uploaded by Buckle.

According to Buckle, even more discoveries may be hiding in wait. Many more original 8-inch floppy disks are in his to-archive queue, including what he believes could be a complete set of MicroPro products such as WordStar and SpellStar—some of the earliest word processing and spellcheck programs. Different operating system disks may also lurk among the remaining floppies. If that weren’t enough, then there are the 5.25-inch disks to explore—all 1,500 or so, according to The Register.

Thanks to Buckle uploading 86-DOS v. 0.1-C to the Internet Archive here, tech wizards are welcome to give the old system a boot-up through an OS emulator such as the Open SIMH Project. For anyone who for whatever reason isn’t skilled in bringing vintage computer operating systems back to life: feel free to check out this video from NTDev showing 86-DOS version 0.1 in (limited) action. And for a deeper dive into the intricate, fascinating history of DOS, there’s this essay series courtesy of the OS/2 Museum.

For decades, images taken of Neptune have looked like the planet has a deep blue hue, while Uranus seemed more green. However, these two ice giants may actually look more similar to eachother than astronomers previously believed. According to a study published January 5 in Monthly Notices of the Royal Astronomical Society, our solar system’s furthest planets’ true colors could both be similar pale shades of greenish blue. 

[Related: The secret to Voyagers’ spectacular space odyssey.]

Images versus reality

NASA’s Voyager 2 mission remains the only flyby of both ice giants conducted by a spacecraft. It gave us the first detailed images of these far-flung planets. Voyager 2 conducted a flyby of Uranus in 1986, and the images revealed a planet with a more pale cyan or blue color. The vessel flew by Neptune in 1989 and the imagery showed a planet with a rich blue color.

However, astronomers have long understood that most modern images of both planets don’t accurately reflect their true colors. Voyager 2 captured images of each planet in separate colors and these single-color images were then put together to make composites. These composite images were not always accurately balanced, particularly for the planet Neptune which was believed to appear too blue. The contrast on the early Voyager images of Neptune were also strongly enhanced to better reveal the clouds and winds of the planet. 

“Although the familiar Voyager 2 images of Uranus were published in a form closer to ‘true’ color, those of Neptune were, in fact, stretched and enhanced, and therefore made artificially too blue,” study co-author and University of Oxford astronomer Patrick Irwin said in a statement. “Even though the artificially-saturated color was known at the time amongst planetary scientists–and the images were released with captions explaining it–that distinction had become lost over time.”

Creating a more accurate view

In the new study, the team applied data taken from the Hubble Space Telescope’s Space Telescope Imaging Spectrograph (STIS) and the Multi Unit Spectroscopic Explorer (MUSE) on the European Southern Observatory’s Very Large Telescope. 

With both the STIS and MUSE, each pixel is a continuous spectrum of colors, so their observations can be processed more clearly to determine the more accurate color of the planets, instead of what is being seen with a filter. 

The team used the data to rebalance the composite color images that were recorded by Voyager 2’s onboard camera and by the Hubble Space Telescope’s Wide Field Camera 3. The rebalancing revealed that both Uranus and Neptune are actually a similar pale shade of greenish blue. Neptune has a slight hint of more blue, which the model showed to be a thin layer of haze on the planet

The changing colors of Uranus

This research also provides a likely answer to why Uranus changes color slightly during its 84 year-long orbit around the sun. The team first compared images of Uranus to measurements of its brightness that were taken at blue and green wavelengths by the Lowell Observatory in Arizona from 1950 to 2016. These measurements showed that Uranus looks a little greener during its summer and winter solstices, when its poles are pointed towards the sun. However, during the equinoxes–when the sun is over the planet’s equator–it appears to have a more blue tinge.

The left-hand disc shows the appearance of Uranus to the naked eye, while the right-hand disc has been color stretched and enhanced to make atmospheric features clearer. In this animation, Uranus’s spin has been slowed down by over 3000 times so that the planetary rotation can be seen, with discrete storm clouds seen passing across the planet’s disc. As the planet moves towards its solstices a pale polar ‘hood’ of increasing cloud opacity and reduced methane abundance can be seen filling more of the planet’s disc leading to seasonal changes in the overall color of the planet. The changing size of Uranus’s disc is due to Uranus’s distance from the Sun changing during its orbit. Patrick Irwin/University of Oxford

One already established reason for the change is due to Uranus’ a highly unusual spin. The planet spins almost on its side during orbit, so its north and south poles point almost directly towards the sun and Earth during its solstices. Any changes to the reflectivity of Uranus’ poles would have a major impact on the planet’s overall brightness when viewed from the Earth, according to the authors. What was less clear to astronomers was how and why this reflectivity differs. The team developed a model to compare the bands of colors of Uranus’s polar regions to its equatorial regions. 

They found that polar regions are more reflective at green and red wavelengths than at blue wavelengths. Uranus is more reflective at these wavelengths partially because gas methane absorbs the color red and methane is about half as abundant near Uranus’ poles than the equator.

[Related: Neptune’s bumpy childhood could reveal our solar system’s missing planets.]

However, this wasn’t enough to fully explain the color change so the researchers added a new variable to the model in the form of a ‘hood’ of gradually thickening icy haze which has previously been observed when Uranus moves from equinox to summer solstice. They believe that this haze is likely made up of methane ice particles.

After simulating this pole shift in the model, the ice particles further increased the reflection at green and red wavelengths at the planet’s poles, which explained that Uranus looks greener at the solstice due to less methane at the poles and increased thickness of the methane ice particles. 

“The misperception of Neptune’s color, as well as the unusual color changes of Uranus, have bedeviled us for decades,” Heidi Hammel, of the Association of Universities for Research in Astronomy said in a statement. “This comprehensive study should finally put both issues to rest.” Hammel is not an author of the new study. 

Filling in this gap between the public perception of Neptune and its reality shows how data can be manipulated to show off certain features of a planet or enhance visualizations. 

“There’s never been an attempt to deceive,” study co-author and University of Leicester planetary scientist Leigh Fletcher told The New York Times. “But there has been an attempt to tell a story with these images by making them aesthetically pleasing to the eye so that people can enjoy these beautiful scenes in a way that is, maybe, more meaningful than a fuzzy, gray, amorphous blob in the distance.”

The city hopes any potential aliens in the TRAPPIST-1 system will learn bourbon, horses, and bluegrass are worth the 40 light-year journey, although the message might not survive the trip.

Signs of humanity have traveled through space ever since the very first radio signals left the Earth’s atmosphere. We even made concerted efforts to broadcast evidence of our existence through projects like the historic Voyager spacecraft recordings—but an official intergalactic tourism campaign advertising alien vacations to the “Horse Capital of the Word?” That’s a first.

[ Related: How scientists decide if they’ve actually found signals of alien life ]

The Lexington Convention and Visitors Bureau (VisitLEX) recently turned to University of Kentucky professor and longtime SETI advocate, Robert Lodder, to assemble experts from various disciplines including linguistics, philosophy, and design to attract a unique target audience: (potential) extraterrestrial lifeforms. More specifically, any extraterrestrial life possibly residing within the TRAPPIST-1 system.

Located approximately 40 light-years away in the Leo constellation, TRAPPIST-1 is by far the most studied planetary system outside of our own. There, seven rocky planets orbit a small red dwarf star, three of which reside within its “Goldilocks zone”—the region astrobiologists believe could be conducive to supporting life.

“Many previous transmissions have employed the language of mathematics for communication, and our team did, too,” Lodder tells PopSci. “But we decided that extraterrestrials might be more interested in things unique to Planet Earth than Universal Truths like mathematics, so if we seek to attract visitors, it would be best to send something interesting and uniquely Earth.”

Collaborators ultimately decided on a package including black-and-white photographs of rolling Kentucky bluegrass hills, an audio recording of local blues legend, Tee Dee Young, and an original bitmap illustration—a type of image in which programmers use basic coding to create a grid with shaded blocks that form rudimentary images. Among other subjects, this bitmap art includes renderings of humans, horses, the elements necessary for life (as we know it), alongside the chemical composition maps of ethanol and water, aka alcohol—more specifically to Kentucky, bourbon.

With the message’s contents compiled, Lodder’s team then converted their advertisement into a one-dimensional array of light pulses using a computer-laser interface aimed at TRAPPIST-1. On a clear, dark autumn evening, VisitLEX hosted researchers and local guests at Kentucky Horse Park to fire off their tourism package into space.

While lasers are increasingly replacing radio communications in space due their increased data storage capabilities and lower costs, transmissions must be strong enough to travel millions of miles without degrading. This requires equally strong equipment, such as the Deep Space Optical Communications array aboard NASA’s Psyche spacecraft.

VisitLEX’s laser is far weaker than NASA’s equipment, but Lodder believes that at least some of the transmission’s light photons “will almost certainly” reach TRAPPIST-1. That said, it’s difficult to know if there will be enough photons to fully decode their message.

“The alien receiving technology could be worse than ours, or much better,” says Lodder.

[ Related: JWST just scanned the skies of potentially habitable exoplanet TRAPPIST-1 b ]

Regardless, if ETs ever do make a pitstop in Lexington because of VisitLEX’s interstellar commercial, it likely won’t happen until at least the year 2103—40 light-years for the broadcast to reach TRAPPIST-1, followed by another 40 light-years to travel the approximately 235-million mile trek over to Earth, assuming they’re capable of traveling at the speed of light. It all might sound like a lot both logistically and technologically, but both VisitLEX and Lodder’s team swear it’s worth the planning.

[ Related: To set the record straight: Nothing can break the speed of light ]

If there’s anyone out there listening and able to pick up this kind of admittedly weak signal—and if they have a taste for oak barrel aged bourbon and/or horses—well…

Update 1/12/24 9:00am: PopSci received the following response from Jan McGarry, Next Generation Satellite Laser Ranging Systems Deputy Lead at the NASA Goddard Space Flight Center, and her retired colleague, John Degnan:
“The distance to the nearest star is 2 light years away or many orders of magnitude farther than the edge of our solar system (Pluto). Since the strength of a laser communications link is proportional to 1 divided by the distance squared, it is highly unlikely that a laser system would be able to transfer any meaningful amount of information over that distance let alone one 20 times farther away where the signal would be 400 times smaller.”

As more and more Americans embrace electric vehicles, automakers and the federal government are racing to secure the materials needed to build EV batteries, including by pouring billions of dollars into battery recycling. Today, recyclers are focused on recovering valuable metals like nickel and cobalt from spent lithium-ion batteries. But with the trade war between the U.S. and China escalating, some are now taking a closer look at another battery mineral that today’s recycling processes treat as little more than waste.

On December 1, China implemented new export controls on graphite, the carbon-based mineral that’s best known for being used in pencils but that’s also used in a more refined form in commercial EV battery anodes. The new policies, which the Chinese government announced in October shortly after the Biden administration increased restrictions on exports of advanced semiconductors to China, have alarmed U.S. lawmakers and raised concerns that battery makers outside of China will face new challenges securing the materials needed for anodes. Today, China dominates every step of the battery anode supply chain, from graphite mining and synthetic graphite production to anode manufacturing.

Along with a new federal tax credit that rewards automakers that use minerals produced in America, China’s export controls are boosting the U.S. auto industry’s interest in domestically sourced graphite. But while it could take many years to set up new graphite mines and production facilities, there is another, potentially faster option: Harvesting graphite from dead batteries. As U.S. battery recyclers build big new facilities to recover costly battery metals, some are also trying to figure out how to recycle battery-grade graphite—something that isn’t done at scale anywhere in the world today due to technical and economic barriers. These companies are being aided by the U.S. Department of Energy, which is now pouring tens of millions of dollars into graphite recycling initiatives aimed at answering basic research questions and launching demonstration plants.

If the challenges holding back commercial graphite recycling can be overcome, “the used graphite stream could be huge,” Matt Keyser, who manages the electrochemical energy storage group at the the Department of Energy’s National Renewable Energy Laboratory, told Grist. In addition to boosting domestic supplies, recycling graphite would prevent critical battery resources from being wasted and could reduce the carbon emissions tied to battery production.

To understand why graphite is hard to recycle, a bit of material science is necessary. Graphite is a mineral form of carbon that has both metallic and non-metallic properties, including high electrical and thermal conductivity and chemical inertness. These qualities make it useful for a variety of energy and industrial applications, including storing energy inside lithium-ion batteries. While a lithium-ion battery is charging, lithium ions flow from the metallic cathode into the graphite anode, embedding themselves between crystalline layers of the carbon atoms. Those ions are released while the battery is in use, generating an electrical current.

Graphite can be found in nature as crystalline flakes or masses, which are mined and then processed to produce the small, spherical particles needed for anode manufacturing. Graphite is also produced synthetically by heating byproducts of coal or petroleum production to temperatures greater than 2,500 degrees Celsius (about 4,500 degrees Fahrenheit)—an energy-intensive (and often emissions-intensive) process that triggers “graphitization” of the carbon atoms. 

Relatively cheap to mine or manufacture, graphite is lower in value than many of the metals inside battery cathodes, which can include lithium, nickel, cobalt, and manganese. Because of this, battery recyclers traditionally haven’t taken much interest in it. Instead, with many battery recyclers hailing from the metals refining business, they’ve focused on what they already knew how to do: extracting and purifying those cathode metals, often in their elemental form. Graphite, which can comprise up to 30 percent of an EV battery by weight, is treated as a byproduct, with recyclers either burning it for energy or separating it out to be landfilled.

“Up until recently, people talking about recycling for batteries really went after those token [metal] elements because they were high value … and because that recycling process can overlap quite a bit with conventional metal processing,” Ryan Melsert, the CEO of U.S. battery materials startup American Battery Technology Company, told Grist.

For graphite recycling to be worthwhile, recyclers need to obtain a high-performance, battery-grade product. To do so, they need methods that separate the graphite from everything else, remove any contaminants like metals and glues, and restore the material’s original geometric structure, something that’s often done by applying intense heat.

Crude recycling approaches like pyrometallurgy, a traditional process in which batteries are smelted in a furnace, won’t work for graphite. “More than likely you’re going to burn off the graphite” using pyrometallurgy, Keyser said.

Today, the battery recycling industry is moving away from pyrometallurgy and embracing hydrometallurgical approaches, in which dead batteries are shredded and dissolved in chemical solutions to extract and purify various metals. Chemical extraction approaches could be adapted for graphite purification, although there are still “logistical issues,” according to Keyser. Most hydrometallurgical recycling processes use strong acids to extract cathode metals, but those acids can damage the crystalline structure of graphite. A longer or more intensive heat treatment step may be needed to restore graphite’s shape after extraction, driving up energy usage and costs.

A third approach is direct recycling, in which battery materials are separated and repaired for reuse without any smelting or acid treatment. This gentler process aims to keep the structure of the materials intact. Direct recycling is a newer idea that’s further from commercialization than the other two methods, and there are some challenges scaling it up because it relies on separating materials very cleanly and efficiently. But recent research suggests that for cathode metals, it can have significant environmental and cost benefits. Direct recycling of graphite, Keyser said, has the potential to use “far less energy” than synthetic graphite production.

Today, companies are exploring a range of graphite recycling processes. 

American Battery Technology Company has developed an approach that starts with physically separating graphite from other battery materials like cathode metals, followed by a chemical purification step. Additional mechanical and thermal treatments are then used to restore graphite’s original structure. The company is currently recycling graphite at a “very small scale” at its laboratory facilities in Reno, Nevada, Melsert said. But in the future, it plans to scale up to recycling several tons of graphite-rich material a day with the help of a three-year, nearly $10 million Department of Energy grant funded through the 2021 bipartisan infrastructure law.

Massachusetts-based battery recycling startup Ascend Elements has also developed a chemical process for graphite purification. Dubbed “hydro-to-anode,” Ascend Elements’ process “comes from some of the work we’ve done on hydro-to-cathode,” the company’s patented hydrometallurgical process for recycling cathode materials, said Roger Lin, the vice president of global marketing and government relations at the firm. Lin said that Ascend Elements is able to take graphite that’s been contaminated during an initial shredding step back to 99.9 percent purity, exceeding EV industry requirements, while also retaining the material properties needed for high performance anodes. In October, Ascend Elements and Koura Global announced plans to build the first “advanced graphite recycling facility” in the U.S.

The Department of Energy-backed startup Princeton NuEnergy, meanwhile, is exploring direct recycling of graphite. Last year, Princeton NuEnergy opened the first pilot-scale direct recycling plant in the U.S. in McKinney, Texas. There, batteries are shredded and a series of physical separation processes are used to sort out different materials, including cathode and anode materials. Cathode materials are then placed in low-temperature reactors to strip away contaminants, followed by additional steps to reconstitute their original structure. The same general approach can be used to treat anode materials, according to founder and CEO Chao Yan. 

“From day one, we are thinking to get cathode and anode material both recycled,” Yan said. But until now, the company has focused on commercializing direct recycling for cathodes. The reason, Yan said, is simple: “No customer cared about anode materials in the past.”

That, however, is beginning to change. Yan said that over the past year—and especially in the last few months since China announced its new export controls—automakers and battery manufacturers have taken a greater interest in graphite recycling. Melsert also said that he’s starting to see “very significant interest” in recycled graphite.

Still, customers will have to wait a little longer before they can purchase recycled graphite for their batteries. The methods for purifying and repairing graphite still need refinement to reduce the cost of recycling, according to Brian Cunningham, the batteries R&D program manager at the Department of Energy’s Vehicle Technologies Office. Another limiting step is what Cunningham calls the “materials qualification step.” 

“We need to get recycled graphite to a level where companies can provide material samples to battery companies to evaluate the material,” Cunningham said. The process of moving from very small-scale production to levels that allow EV makers to test a product, “could take several years to complete,” he added. “Once the recycled graphite enters the evaluation process, we should start to see an uptick in companies setting up pilot- and commercial-scale equipment.“

Supply chain concerns could accelerate graphite recycling’s journey to commercialization. Over the summer, the Department of Energy added natural graphite to its list of critical materials for energy. Graphite is also on the U.S. Geological Survey’s list of critical minerals — minerals that are necessary for advanced technologies but at risk of supply disruptions. 

This classification means that domestically sourced graphite can help EVs qualify for the “clean vehicle credit,” a tax credit that includes strict requirements around critical mineral sourcing following the 2022 Inflation Reduction Act. To qualify for the full credit, EV makers must obtain a large fraction of their battery minerals from the U.S. or a free-trade partner. By 2025, their vehicles may not contain any critical minerals extracted or processed by a “foreign entity of concern” — an entity connected to a shortlist of foreign countries that includes China. This requirement could “drive a premium” for domestically recycled graphite, Lin said.

Tax incentives could be key to helping recycled graphite compete with virgin graphite, according to Yuan Gu, a graphite analyst at the consulting firm Benchmark Mineral Intelligence. Despite China’s new export controls, Gu expects graphite to remain relatively cheap in the near future due to an “oversupply” of graphite on the market right now. While Gu said that graphite recycling is “definitely on radar for Western countries” interested in securing future supplies, its viability will depend on “how costly or cheap the recycled material will be.”

If graphite recycling does catch on, industry insiders are hopeful it will be able to meet a significant fraction of the country’s future graphite needs—which are growing rapidly as the clean energy transition accelerates—while making the entire EV battery supply chain more sustainable.

“You can help regional supply chains, you can help with efficiency, with carbon footprints,” Lin said.  “I think it’s a no-brainer this will happen.”
