Meta is reportedly set to invest $15 billion to acquire a 49% stake in Scale AI, in a deal that would make Scale CEO Alexandr Wang head of the tech giant’s new AI unit dedicated to pursuing “superintelligence.”Scale AI, founded in 2016, is a leading data annotation firm that hires workers around the world to label or create the data that is used to train AI systems.The deal is expected to greatly enrich Wang and many of his colleagues with equity in Scale AI; Wang, already a billionaire, would see his wealth grow even further. For Meta, it would breathe new life into the company’s flagging attempts to compete at the “frontier” of AI against OpenAI, Google, and Anthropic.However, Scale’s contract workers, many of whom earn just dollars per day via a subsidiary called RemoTasks, are unlikely to benefit at all from the deal, according to sociologists who study the sector. Typically data workers are not formally employed, and are instead paid for the tasks they complete. Those tasks can include labeling the contents of images, answering questions, or rating which of two chatbots’ answers are better, in order to teach AI systems to better comply with human preferences.(TIME has a content partnership with Scale AI.)“I expect few if any Scale annotators will see any upside at all,” says Callum Cant, a senior lecturer at the University of Essex, U.K., who studies gig work platforms. “It would be very surprising to see some kind of feed-through. Most of these people don’t have a stake in ownership of the company.”Many of those workers already suffer from low pay and poor working conditions. In a recent report by Oxford University’s Internet Institute, the Scale subsidiary RemoTasks failed to meet basic standards for fair pay, fair contracts, fair management, and fair worker representation.Advertisement“A key part of Scale’s value lies in its data work services performed by hundreds of thousands of underpaid and poorly protected workers,” says Jonas Valente, an Oxford researcher who worked on the report. “The company remains far from safeguarding basic standards of fair work, despite limited efforts to improve its practices.”The Meta deal is unlikely to change that. “Unfortunately, the increasing profits of many digital labor platforms and their primary companies, such as the case of Scale, do not translate into better conditions for [workers],” Valente says.A Scale AI spokesperson declined to comment for this story. “We're proud of the flexible earning opportunities offered through our platforms,” the company said in a statement to TechCrunch in May. Meta’s investment also calls into question whether Scale AI will continue supplying data to OpenAI and Google, two of its major clients. In the increasingly competitive AI landscape, observers say Meta may see value in cutting off its rivals from annotated data — an essential means of making AI systems smarter. Advertisement“By buying up access to Scale AI, could Meta deny access to that platform and that avenue for data annotation by other competitors?” says Cant. “It depends entirely on Meta’s strategy.”If that were to happen, Cant says, it could put downward pressure on the wages and tasks available to workers, many of whom already struggle to make ends meet with data work.A Meta spokesperson declined to comment on this story.

All images courtesy of Ella Hawkins, shared with permission Dr. Ella Hawkins Reimagines Ancient Artifacts and Prized Objects as Edible Replicas May 31, 2025 Grace Ebert Academic research is notoriously niche and often opaque, but Dr. Ella Hawkins has found a crowd-pleasing way to share her studies. The Birmingham-based artist and design historian translates her interests in Shakespeare performance, costume, and matieral culture into edible replicas. Hawkins bakes batches of cookies that she tops with royal icing. Decorating takes a scholarly turn, as she uses tiny paintbrushes and a mini projector to help trace imagery of William Morris’ ornate floral motifs or coastal scenes from English delftware. Rendering a design on a single cookie can take anywhere between two and four hours, depending on the complexity. Unsurprisingly, minuscule calligraphy and portraits are most demanding. Ancient Greek Pottery Sherds Hawkins first merged baking and her research about a decade ago while studying undergraduate costume design at the University of Warwick. She decided to bake cupcakes based on Shakespeare productions that her class examined. “It felt like a fun way to look back at all the different design styles we’d covered through the year,” she tells Colossal, adding: I carried on decorating cakes and cookies based on costume design through my PhD (mainly as goodies to give out during talks, or as gifts for designers that I interviewed), then branched out and spent lots of time doing cookie versions of other artefacts to keep busy during the pandemic. She has since published an academic book on the topic and is a senior lecturer at Royal Welsh College of Music and Drama. But she also continues to translate artifacts and prized objects held within museum collections into delicious canvases. There’s a set made in collaboration with Milton’s Cottage, a museum in the country house where John Milton finished his epic Paradise Lost. Anchored by a delicately crosshatched portrait evoking that of the frontispiece, the collection contains typographic titles and signs that appear straight from a 17th-century book. Delftware Tiles Hawkins ventures farther back in history to ancient Greece with a collection of pottery sherds inspired by objects within the Ashmolean Museum. With a bowed surface to mimic a vessel’s curvature, the irregular shapes feature fragments of various motifs and figures to which she applied a sgraffito technique, a Renaissance method of scratching a surface to reveal the layer below. The weathered appearance is the result of blotting a base of pale brown-grey before using a scribe tool to scratch and crack the royal icing coating the surface. She then lined these etchings with a mix of vodka and black food coloring to mimic dirt and wear. (It’s worth taking a look at this process video.)

Comparison of a megalodon tooth and a great white shark tooth, not associated with the study. (Image Credit: Mark_Kostich/Shutterstock) NewsletterSign up for our email newsletter for the latest science newsMegalodon teeth have always been key to understanding the ancient marine predator. Fossilized teeth are all that remain to prove the existence of these massive sharks, and the name megalodon is from the Greek for “big tooth.”A new study, published in Earth and Planetary Science Letters, highlights the importance of the megalodon’s human-hand-sized teeth once again. Thanks to extracting and analyzing the traces of zinc left in the fossilized teeth, researchers now know that the megalodon’s diet was much broader than scientists once believed.“Megalodon was by all means flexible enough to feed on marine mammals and large fish, from the top of the food pyramid as well as lower levels – depending on availability,” said Jeremy McCormack from the Department of Geosciences at Goethe University, in a press release.What Did the Megalodon Eat?Clocking in at 78 feet in length and weighing about twice as much as a semi truck, the megalodon was a big fish with a big appetite. It is suggested that a member of the Otodus shark family would require about 100,000 kilocalories per day to survive. Due to this extreme number, scientists have often assumed that the megalodon’s main source of calories came from whales.This new study suggests that whales were not the only item on the megalodon’s daily menu and that these sharks were actually quite adaptable when it came to their food. The research team analyzed 18-million-year-old giant teeth that came from two fossil deposits in Sigmaringen and Passau. What they were looking for was the presence of zinc-66 and zinc-64, two isotopes commonly ingested with food. Typically, the higher up in a food pyramid an animal is, the lower the presence of zinc. As they are oftentimes at the top of the food chain, species such as Otodus megalodon and Otodus chubutensis have a low ratio of zinc-66 to zinc-64 compared to species lower on the food chain.“Sea bream, which fed on mussels, snails, and crustaceans, formed the lowest level of the food chain we studied,” said McCormack in the press release. “Smaller shark species such as requiem sharks and ancestors of today’s cetaceans, dolphins, and whales, were next. Larger sharks, such as sand tiger sharks, were further up the food pyramid, and at the top were giant sharks like Araloselachus cuspidatus and the Otodus sharks, which include megalodon.”Surprisingly, the zinc levels in the megalodon teeth weren’t always that different from the zinc levels in species lower down the food chain. This result means that the commonly held scientific belief that megalodons focused their attention on eating large marine mammals may be incorrect. Instead, McCormack refers to the megalodon as an “ecologically versatile generalist” that adapted to environmental and regional constraints that changed the availability and variety of their prey.A New Method in Teeth TestingUsing the zinc content of fossilized teeth is a relatively new method of analysis, and the research team working on the megalodon couldn’t be happier with their results. The methods used in this study have not only been used for prehistoric shark and whale species but also modern-day shark species, and have even been used on herbivorous prehistoric rhinoceroses.Overall, these new methods have begun to rewrite the history of megalodon’s eating habits and may help to explain more about why these giants of the food chain went extinct. “[Determining zinc isotope ratios] gives us important insights into how the marine communities have changed over geologic time, but more importantly the fact that even ‘supercarnivores’ are not immune to extinction,” said Kenshu Shimada, a paleobiologist at DePaul University and a coauthor of this study, in the press release.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

What if there were a battery that could release energy while trapping carbon dioxide? This isn’t science fiction; it’s the promise of lithium-carbon dioxide (Li-CO₂) batteries, which are currently a hot research topic. Li-CO₂ batteries could be a two-in-one solution to the current problems of storing renewable energy and taking carbon emissions out of the air. They absorb carbon dioxide and convert it into a white powder called lithium carbonate while discharging energy. These batteries could have profound implications for cutting emissions from vehicles and industry—and might even enable long-duration missions on Mars, where the atmosphere is 95% CO₂. To make these batteries commercially viable, researchers have mainly been wrestling with problems related to recharging them. Now, our team at the University of Surrey has come up with a promising way forward. So how close are these “CO₂-breathing” batteries to becoming a practical reality? Like many great scientific breakthroughs, Li-CO₂ batteries were a happy accident. Slightly over a decade ago, a U.S.-French team of researchers were trying to address problems with lithium air batteries, another frontier energy-storage technology. Whereas today’s lithium-ion batteries generate power by moving and storing lithium ions within electrodes, lithium air batteries work by creating a chemical reaction between lithium and oxygen. The problem has been the “air” part, since even the tiny (0.04%) volume of CO₂ that’s found in air is enough to disrupt this careful chemistry, producing unwanted lithium carbonate (Li₂CO₃). As many battery scientists will tell you, the presence of Li₂CO₃ can also be a real pain in regular lithium-ion batteries, causing unhelpful side reactions and electrical resistance. Nonetheless the scientists noticed something interesting about this CO₂ contamination: It improved the battery’s amount of charge. From this point on, work began on intentionally adding CO₂ gas to batteries to take advantage of this, and the lithium-CO₂ battery was born. How it works Their great potential relates to the chemical reaction at the positive side of the battery, where small holes are cut in the casing to allow CO₂ gas in. There it dissolves in the liquid electrolyte (which allows the charge to move between the two electrodes) and reacts with lithium that has already been dissolved there. During this reaction, it’s believed that four electrons are exchanged between lithium ions and carbon dioxide. This electron transfer determines the theoretical charge that can be stored in the battery. In a normal lithium-ion battery, the positive electrode exchanges just one electron per reaction. (In lithium air batteries, it’s two to four electrons.) The greater exchange of electrons in the lithium-carbon dioxide battery, combined with the high voltage of the reaction, explains their potential to greatly outperform today’s lithium-ion batteries. However, the technology has a few issues. The batteries don’t last very long. Commercial lithium-ion packs routinely survive 1,000 to 10,000 charging cycles; most LiCO₂ prototypes fade after fewer than 100. They’re also difficult to recharge. This requires breaking down the lithium carbonate to release lithium and CO₂, which can be energy intensive. This energy requirement is a little like a hill that must be cycled up before the reaction can coast, and is known as overpotential. You can reduce this requirement by printing the right catalyst material on the porous positive electrode. Yet these catalysts are typically expensive and rare noble metals, such as ruthenium and platinum, making for a significant barrier to commercial viability. Our team has found an alternative catalyst, caesium phosphomolybdate, which is far cheaper and easy to manufacture at room temperature. This material made the batteries stable for 107 cycles, while also storing 2.5 times as much charge as a lithium ion. And we significantly reduced the energy cost involved in breaking down lithium carbonate, for an overpotential of 0.67 volts, which is only about double what would be necessary in a commercial product. Our research team is now working to further reduce the cost of this technology by developing a catalyst that replaces caesium, since it’s the phosphomolybdate that is key. This could make the system more economically viable and scalable for widespread deployment. We also plan to study how the battery charges and discharges in real time. This will provide a clearer understanding of the internal mechanisms at work, helping to optimize performance and durability. A major focus of upcoming tests will be to evaluate how the battery performs under different CO₂ pressures. So far, the system has only been tested under idealized conditions (1 bar). If it can work at 0.1 bar of pressure, it will be feasible for car exhausts and gas boiler flues, meaning you could capture CO₂ while you drive or heat your home. Demonstrating that this works will be an important confirmation of commercial viability, albeit we would expect the battery’s charge capacity to reduce at this pressure. By our rough calculations, 1kg of catalyst could absorb around 18.5kg of CO₂. Since a car driving 100 miles emits around 18kg to 20kg of CO₂, that means such a battery could potentially offset a day’s drive. If the batteries work at 0.006 bar, the pressure on the Martian atmosphere, they could power anything from an exploration rover to a colony. At 0.0004 bar, Earth’s ambient air pressure, they could capture CO₂ from our atmosphere and store power anywhere. In all cases, the key question will be how it affects the battery’s charge capacity. Meanwhile, to improve the battery’s number of recharge cycles, we need to address the fact that the electrolyte dries out. We’re currently investigating solutions, which probably involve developing casings that only CO₂ can move into. As for reducing the energy required for the catalyst to work, it’s likely to require optimizing the battery’s geometry to maximize the reaction rate—and to introduce a flow of CO₂, comparable to how fuel cells work (typically by feeding in hydrogen and oxygen). If this continued work can push the battery’s cycle life above 1,000 cycles, cut overpotential below 0.3 V, and replace scarce elements entirely, commercial Li-CO₂ packs could become reality. Our experiments will determine just how versatile and far-reaching the battery’s applications might be, from carbon capture on Earth to powering missions on Mars.

Clownfish Shrink Down Their Bodies to Survive Ocean Heat Waves, New Study Suggests The adaptation appears to help the fish cope with high temperatures, since individuals and breeding pairs that shrank improved their survival odds Clownfish seem to become shorter during heat waves, according to the new study. Morgan Bennett-Smith A new study reveals that clownfish use a surprising strategy to adapt their bodies to ocean heat waves: They shrink. “[Clownfish] have these amazing abilities that we still don’t know all that much about,” says study co-author Theresa Rueger, a tropical marine ecologist at Newcastle University in England, to the Washington Post’s Dino Grandoni. The findings offer some hope for fish in the face of climate change, she adds. “There’s potential that maybe some other species will adapt in a way that will allow them to hang on longer than we think.” Rueger and her team didn’t initially plan to study a heat wave. They were monitoring how freshwater runoff might affect breeding clownfish in Papua New Guinea’s Kimbe Bay, when temperatures dramatically rose and warmed the water to 7.2 degrees Fahrenheit above average. But these conditions, they realized, offered a key opportunity for research. The scientists measured 134 clownfish in Kimbe Bay every month during the ocean heat wave, which spanned from February to August 2023. Astoundingly, 100 of those fish shrank. The researchers found that 71 percent of the dominant females and 79 percent of the breeding males reduced in size at least once over the study period. Their findings were published in the journal Science Advances on Wednesday. At first, lead author Melissa Versteeg, a PhD researcher at England’s Newcastle University, thought she was making a mistake in her measurements. She kept trying again. And again. “She had several people measuring them at the same time to really make sure that we’re confident with the numbers,” Rueger says to Melissa Hobson at National Geographic. But after these repeated attempts, she concluded the measurements were correct. The fish that shrank increased their chances of surviving the heat wave by 78 percent, according to the study. Some of the clownfish even shrank in pairs, reducing their size alongside their breeding partner—a move that also boosted their chance of survival. The study marks the first time a coral reef-dwelling fish has been documented to shrink in response to environmental and social cues, according to a statement from Newcastle University. A pair of clownfish swims near an anemone. When the studied fish became smaller, females maintained a larger size than males. Morgan Bennett-Smith Clownfish aren’t the only animals shifting their size because of heat. Fish around the world are adapting to warmer temperatures by downsizing their bodies. “This is another tool in the toolbox that fish are going to use to deal with a changing world,” says Simon Thorrold, an ocean ecologist at Woods Hole Oceanographic Institution who was not involved in the new work, to Adithi Ramakrishnan at the Associated Press. But these clownfish stand out from the rest. “Until now, when talking about shrinking fish, nearly all studies do not mean that fish literally shrink but that they grow to smaller sizes,” explains Asta Audzijonyte, a senior lecturer at the University of Tasmania in Australia who was not involved in the work, to the Washington Post. “This study, in contrast, reports observations of [clownfish] actually shrinking by a few percent of their total length over the course of a month.” Previous research has found that other animals, like birds and rodents, appear to have gotten smaller because of climate change. And marine iguanas will shrink in response to warmer water temperatures during El Niño years. The researchers don’t yet know how the clownfish are pulling off their shrinking act. One hypothesis is that the fish are reabsorbing their own bone matter, reports the Associated Press. They’re also not sure why, exactly, changing size is so advantageous to the clownfish. But it could be that a smaller size makes it easier to maintain oxygen levels or get by with less food available. “If you’re small, you obviously need less food, and you’re also more efficient in foraging a lot of the time,” explains Rueger to National Geographic. Still, this adaptation method can only go so far. The heat wave exacerbated coral bleaching, which decreases available reef habitat, and subsequent heat waves ultimately killed many of the fish the researchers studied. “We’ve lost many of those fish,” Rueger says to the Washington Post.

Dogs have been man’s best friend for centuries. In recent decades, those furry friends have transitioned into “fur babies,” with many people opting for dog ownership over traditional parenthood. But what does choosing dogs over children say about our society and the way we think about family?In a study published in European Psychologist, a research team from Eötvös Loránd University suggests that declining global birth rates and increasing dog ownership are related. Although dogs cannot replace children, they can effectively offer people the chance to fulfill the parenting urge without the financial and social demands associated with human offspring.“Among many factors, the relatively short lifespan of dogs might contribute to it, as most people expect to outlive their dog, but not their child,” said Laura Gillet, Ph.D. student at the Department of Ethology, in a press release. “Not only individual decisions, but also sociocultural context are crucial to understanding how and why people develop certain types of relationships with their animals.”Why People Choose Dogs Over ChildrenGlobally, especially in wealthy and developed countries, birth rates have steadily declined. In these same countries, dog ownership has only continued to skyrocket, with more people opting to have a pet instead of having a child.To investigate this phenomenon, researchers completed a comprehensive literature review and came up with a hypothesis: for many people, dogs exist as the perfect compromise. We all have a genetically-embedded drive to nurture, and our social bonds with dogs can satisfy this drive. Furry children allow their owners to achieve emotional outcomes similar to those of traditional parents, including positive emotions, social support, and a sense of purpose. By fulfilling this need for dependence and costing less time and money than human children, parenting dogs is a win-win situation.What Makes Dogs Good Kids?Dogs’ cognitive abilities that allow them to learn and respond to human communication are partly why they’ve been by our side for so long. These special adaptations also aid in developing their social behaviors, many of which are incredibly similar to pre-verbal children. Breeds that are particularly baby-like, such as pugs and French bulldogs, can even exhibit the innocence and helplessness of toddlers.Like children, dogs are also dependent on humans as their caregivers. Domesticated dogs can’t feed themselves, take themselves for walks, or arrange social interactions. Their parents are fully responsible for providing them with the necessary means for survival. Although the expectations are high and dogs become incredibly attached to the humans who take care of them, the commitment is still less than expected for a human child. Even with all these comparisons between fur and biological children, treating dogs this way isn’t universal for all dog owners.“We would like to point out that, contrary to popular belief, only a small minority of dog owners actually treat their pets like human children. In most cases, dog parents choose dogs precisely because they are not like children, and they acknowledge their species-specific needs,” said Eniko Kubinyi, senior author of the study and head of the MTA-ELTE “Momentum” Companion Animals Research Group, in the press release.The Future of Pet ParentingFor the research team, it is important that people remember that dogs don’t always want and need what humans think is best for them. Unfortunately, seeing a dog like a human child often raises ethical concerns. The growing interest in infant-like traits has led to the mass breeding of unhealthy breeds. Additionally, being overprotective and sheltering dogs can result in emotional and behavioral problems.Overall, the study’s authors hope that their findings will result in a broader way of thinking about the bond between people and their pets. Due to increasing social isolation and loneliness in our modern world, dogs are still our best friends, companions, and partners, no matter what shape that relationship takes.Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.

A human can’t shrink away from the threats of climate change. A clownfish, however, can. In a new paper published today in Science Advances, a team of researchers revealed that these tiny “Finding Nemo” fish can actually shrink to survive heat stress, allowing them to overcome the threat of heatwaves.“We were so surprised to see shrinking in these fish,” said Melissa Versteeg, a study author and a Ph.D. student at Newcastle University in the U.K., according to a press release. “In the end, we discovered it was very common in this population.”Clownfish Shrink in SizeA clown anemonefish. (Image Credit: Morgan Bennett-Smith)Climate change has transformed terrestrial and marine habitats and continues to transform them, with heatwaves — or periods of abnormal warmth — having one of the most significant impacts on animals. Studies show, for example, that increasing temperatures have a strong influence on the dimensions of terrestrial and marine species, shaping their size and size variability and contributing to their overall reduction in size over time.But what, exactly, is the effect of marine heatwaves on the clownfish, also known as the clown anemonefish (Amphiprion percula)?Setting out to study how heatwaves transform these fish over time, Versteeg and a team of researchers turned to the wild clownfish population in Kimbe Bay in Papua New Guinea, where heatwaves caused temperatures to sit around 4 degrees Celcius above average over the course of the study. Measuring the water temperatures and the size of the clownfish there from February 2023 to August 2023, the team found that individual clownfish shrank over time.“We measured each fish individual repeatedly over a period of five months,” Versteeg said in the release. “During our study, 100 fish shrank out of the 134 fish that we studied.” Rather than getting slimmer, these clownfish shrank by getting shorter, with the degree of their reduction depending on the individual’s initial size and social rank. According to the researchers, the results reveal that clownfish reduce their size in response to heat stress, which, in turn, increases their chances of surviving a heatwave by 78 percent.Read More: How Volunteers Are Helping Keep Coral Reefs AliveClownfish Survival ImprovesAccording to the researchers, some clownfish shrank one time, and some clownfish shrank multiple times, with all of the fish that shrank multiple times surviving throughout the course of the study. Intriguingly, the chances of clownfish survival were also improved if a clownfish shrank alongside its breeding partner. “We witnessed how flexibly they regulated their size, as individuals and as breeding pairs, in response to heat stress as a successful technique to help them survive.” Versteeg said in the release. “It was a surprise to see how rapidly clownfish can adapt to a changing environment.”Similar shrinking abilities are seen in other animals, including marine iguanas. And while clownfish are the first coral reef fish that researchers have shown to shorten in response to heat stress, they may not be the last. In fact, the results could have implications for other coral reef fish, and for other fish overall. According to the researchers, fish on the whole are much smaller today than they once were. A 2023 study in Science found, for instance, that fish, in particular, are driving a decrease in size in the world’s animal populations. One possible explanation for this is that smaller species of fish are surviving over larger species of fish. Another is that fish species of all sizes are shrinking over time, with the smaller individuals of each species surviving (and thus procreating) more than the larger individuals of each species. It is possible, however, that there are other factors contributing to the smaller size of fish today, too, including the ability to shrink in size in times of stress. “If individual shrinking were widespread and happening among different species of fish, it could provide a plausible alternative hypothesis for why the size many fish species is declining,” said Theresa Rueger, the senior study author and a lecturer at Newcastle University, according to the press release. “Further studies are needed in this area.”Though the fish themselves are small and becoming smaller, the researchers say that their results raise big questions about animal size and about animal shrinking, more specifically. “We don’t know yet exactly how they do it,” Versteeg said. “But we do know that a few other animals can do this too.”Article SourcesOur writers at Discovermagazine.com use peer-reviewed studies and high-quality sources for our articles, and our editors review for scientific accuracy and editorial standards.
