In a new study, researchers from the University of Tokyo, Harvard University, and the International Research Center for Neurointelligence have unveiled a technique for creating lifelike robotic skin using living human cells. As a proof of concept, the team engineered a small robotic face capable of smiling, covered entirely with a layer of pink living tissue.
The researchers note that using living skin tissue as a robot covering has benefits, as it’s flexible enough to convey emotions and can potentially repair itself. “As the role of robots continues to evolve, the materials used to cover social robots need to exhibit lifelike functions, such as self-healing,” wrote the researchers in the study.
The study describes a novel method for attaching cultured skin to robotic surfaces using “perforation-type anchors” inspired by natural skin ligaments. These tiny v-shaped cavities in the robot’s structure allow living tissue to infiltrate and create a secure bond, mimicking how human skin attaches to underlying tissues.
To demonstrate the skin’s capabilities, the team engineered a palm-sized robotic face able to form a convincing smile. Actuators connected to the base allowed the face to move, with the living skin flexing. The researchers also covered a static 3D-printed head shape with the engineered skin.

Takeuchi et al. created their robotic face by first 3D-printing a resin base embedded with the perforation-type anchors. They then applied a mixture of human skin cells in a collagen scaffold, allowing the living tissue to grow into the anchors.
Temu—the Chinese shopping app that has rapidly grown so popular in the US that even Amazon is reportedly trying to copy it—is “dangerous malware” that’s secretly monetizing a broad swath of unauthorized user data, Arkansas Attorney General Tim Griffin alleged in a lawsuit filed Tuesday.
Griffin cited research and media reports exposing Temu’s allegedly nefarious design, which “purposely” allows Temu to “gain unrestricted access to a user’s phone operating system, including, but not limited to, a user’s camera, specific location, contacts, text messages, documents, and other applications.”
“Temu is designed to make this expansive access undetected, even by sophisticated users,” Griffin’s complaint said. “Once installed, Temu can recompile itself and change properties, including overriding the data privacy settings users believe they have in place.”
Griffin fears that Temu is capable of accessing virtually all data on a person’s phone, exposing both users and non-users to extreme privacy and security risks. It appears that anyone texting or emailing someone with the shopping app installed risks Temu accessing private data, Griffin’s suit claimed, which Temu then allegedly monetizes by selling it to third parties, “profiting at the direct expense” of users’ privacy rights.
“Compounding” risks is the possibility that Temu’s Chinese owners, PDD Holdings, are legally obligated to share data with the Chinese government, the lawsuit said, due to Chinese “laws that mandate secret cooperation with China’s intelligence apparatus regardless of any data protection guarantees existing in the United States.”
Griffin’s suit cited an extensive forensic investigation into Temu by Grizzly Research—which analyzes publicly traded companies to inform investors—last September. In their report, Grizzly Research alleged that PDD Holdings is a “fraudulent company” and that “Temu is cleverly hidden spyware that poses an urgent security threat to United States national interests.”
As Griffin sees it, Temu baits users with misleading promises of discounted, quality goods, angling to get access to as much user data as possible by adding addictive features that keep users logged in, like spinning a wheel for deals. Meanwhile hundreds of complaints to the Better Business Bureau showed that Temu’s goods are actually low-quality, Griffin alleged, apparently supporting his claim that Temu’s end goal isn’t to be the world’s biggest shopping platform but to steal data.
Investigators agreed, the lawsuit said, concluding “we strongly suspect that Temu is already, or intends to, illegally sell stolen data from Western country customers to sustain a business model that is otherwise doomed for failure.”
Seeking an injunction to stop Temu from allegedly spying on users, Griffin is hoping a jury will find that Temu’s alleged practices violated the Arkansas Deceptive Trade Practices Act (ADTPA) and the Arkansas Personal Information Protection Act. If Temu loses, it could be on the hook for $10,000 per violation of the ADTPA and ordered to disgorge profits from data sales and deceptive sales on the app.
Temu “surprised” by lawsuit
The company that owns Temu, PDD Holdings, was founded in 2015 by a former Google employee, Colin Huang. It was originally based in China, but after security concerns were raised, the company relocated its “principal executive offices” to Ireland, Griffin’s complaint said. This, Griffin suggested, was intended to distance the company from debate over national security risks posed by China, but because the majority of its business operations remain in China, risks allegedly remain.
PDD Holdings’ relocation came amid heightened scrutiny of Pinduoduo, the Chinese app on which Temu’s shopping platform is based. Last year, Pinduoduo came under fire for privacy and security risks that got the app suspended from Google Play as suspected malware. Experts said Pinduoduo took security and privacy risks “to the next level,” the lawsuit said. And “around the same time,” Apple’s App Store also flagged Temu’s data privacy terms as misleading, further heightening scrutiny of two of PDD Holdings’ biggest apps, the complaint noted.
Researchers found that Pinduoduo “was programmed to bypass users’ cell phone security in order to monitor activities on other apps, check notifications, read private messages, and change settings,” the lawsuit said. “It also could spy on competitors by tracking activity on other shopping apps and getting information from them,” as well as “run in the background and prevent itself from being uninstalled.” The motivation behind the malicious design was apparently “to boost sales.”
According to Griffin, the same concerns that got Pinduoduo suspended last year remain today for Temu users, but the App Store and Google Play have allegedly failed to take action to prevent unauthorized access to user data. Within a year of Temu’s launch, the “same software engineers and product managers who developed Pinduoduo” allegedly “were transitioned to working on the Temu app.”
Google and Apple did not immediately respond to Ars’ request for comment.
A Temu spokesperson provided a statement to Ars, discrediting Grizzly Research’s investigation and confirming that the company was “surprised and disappointed by the Arkansas Attorney General’s Office for filing the lawsuit without any independent fact-finding.”
“The allegations in the lawsuit are based on misinformation circulated online, primarily from a short-seller, and are totally unfounded,” Temu’s spokesperson said. “We categorically deny the allegations and will vigorously defend ourselves.”
While Temu plans to defend against claims, the company also seems to potentially be open to making changes based on criticism lobbed in Griffin’s complaint.
“We understand that as a new company with an innovative supply chain model, some may misunderstand us at first glance and not welcome us,” Temu’s spokesperson said. “We are committed to the long-term and believe that scrutiny will ultimately benefit our development. We are confident that our actions and contributions to the community will speak for themselves over time.”
Enlarge/ Al Michaels looks on prior to the game between the Minnesota Vikings and Philadelphia Eagles at Lincoln Financial Field on September 14, 2023, in Philadelphia, Pennsylvania.
On Wednesday, NBC announced plans to use an AI-generated clone of famous sports commentator Al Michaels‘ voice to narrate daily streaming video recaps of the 2024 Summer Olympics in Paris, which start on July 26. The AI-powered narration will feature in “Your Daily Olympic Recap on Peacock,” NBC’s streaming service. But this new, high-profile use of voice cloning worries critics, who say the technology may muscle out upcoming sports commentators by keeping old personas around forever.
NBC says it has created a “high-quality AI re-creation” of Michaels’ voice, trained on Michaels’ past NBC appearances to capture his distinctive delivery style.
The veteran broadcaster, revered in the sports commentator world for his iconic “Do you believe in miracles? Yes!” call during the 1980 Winter Olympics, has been covering sports on TV since 1971, including a high-profile run of play-by-play coverage of NFL football games for both ABC and NBC since the 1980s. NBC dropped him from NFL coverage in 2023, however, possibly due to his age.
Michaels, who is 79 years old, shared his initial skepticism about the project in an interview with Vanity Fair, as NBC News notes. After hearing the AI version of his voice, which can greet viewers by name, he described the experience as “astonishing” and “a little bit frightening.” He said the AI recreation was “almost 2% off perfect” in mimicking his style.
The Vanity Fair article provides some insight into how NBC’s new AI system works. It first uses a large language model (similar technology to what powers ChatGPT) to analyze subtitles and metadata from NBC’s Olympics video coverage, summarizing events and writing custom output to imitate Michaels’ style. This text is then fed into an unspecified voice AI model trained on Michaels’ previous NBC appearances, reportedly replicating his unique pronunciations and intonations.
NBC estimates that the system could generate nearly 7 million personalized variants of the recaps across the US during the games, pulled from the network’s 5,000 hours of live coverage. Using the system, each Peacock user will receive about 10 minutes of personalized highlights.
A diminished role for humans in the future?
Enlarge/ Al Michaels reports on the Sweden vs. USA men’s ice hockey game at the 1980 Olympic Winter Games on February 12, 1980.
It’s no secret that while AI is wildly hyped right now, it’s also controversial among some. Upon hearing the NBC announcement, critics of AI technology reacted strongly. “@NBCSports, this is gross,” tweeted actress and filmmaker Justine Bateman, who frequently uses X to criticize technologies that might replace human writers or performers in the future.
A thread of similar responses from X users reacting to the sample video provided above included criticisms such as, “Sounds pretty off when it’s just the same tone for every single word.” Another user wrote, “It just sounds so unnatural. No one talks like that.”
The technology will not replace NBC’s regular human sports commentators during this year’s Olympics coverage, and like other forms of AI, it leans heavily on existing human work by analyzing and regurgitating human-created content in the form of captions pulled from NBC footage.
Looking down the line, due to AI media cloning technologies like voice, video, and image synthesis, today’s celebrities may be able to attain a form of media immortality that allows new iterations of their likenesses to persist through the generations, potentially earning licensing fees for whoever holds the rights.
We’ve already seen it with James Earl Jones playing Darth Vader’s voice, and the trend will likely continue with other celebrity voices, provided the money is right. Eventually, it may extend to famous musicians through music synthesis and famous actors in video-synthesis applications as well.
The possibility of being muscled out by AI replicas factored heavily into a Hollywood actors’ strike last year, with SAG-AFTRA union President Fran Drescher saying, “If we don’t stand tall right now, we are all going to be in trouble. We are all going to be in jeopardy of being replaced by machines.”
For companies that like to monetize media properties for as long as possible, AI may provide a way to maintain a media legacy through automation. But future human performers may have to compete against all of the greatest performers of the past, rendered through AI, to break out and forge a new career—provided there will be room for human performers at all.
“Al Michaels became Al Michaels because he was brought in to replace people who died, or retired, or moved on,” tweeted a writer named Geonn Cannon on X. “If he can’t do the job anymore, it’s time to let the next Al Michaels have a shot at it instead of just planting a code-generated ghoul in an empty chair.“

There was a logo and a Series S-ish circle on the top of the Keystone Xbox, but there are no cutouts depicted, so this may have been a stylistic choice rather than a place for the console to vent hot air.
Microsoft
Microsoft’s mid-generation plans for the Xbox Series S and X consoles looked a whole lot different a couple of years ago than it does now. A leaked slide deck from the FTC v. Microsoft case last year outlined detailed plans for a spruced up Series S, an overhauled Series X, and even a redesigned controller. Another part of that roadmap included a streaming-only version of the Xbox, codenamed Keystone, that was designed to connect to Microsoft’s Xbox Cloud Gaming servers rather than rendering games locally.
Microsoft has talked openly about this version of the Xbox before. Microsoft Gaming CEO Phil Spencer told The Verge that the Keystone console was designed and fully functional, but that it wasn’t launched because Microsoft had a hard time getting the price down low enough that it made sense next to the $299 Series S (which already occasionally goes on sale in the $200 to $250 range).
We’ve already seen glimpses of Keystone—once on Spencer’s shelf, and again in the FTC v. Microsoft documents. Both of those depictions were partial, or seen from a distance. But a new design patent document (PDF) unearthed by Windows Central shows even more detailed renderings of what the cloud Xbox would have looked like.
Series S meets Apple TV
Keystone’s styling was strongly reminiscent of the disc-drive-less Series S, with the same boxy white design and front-mounted Xbox button and USB port. There’s also a similar circular cutout on top, though it may not be an air vent as it is in the Series S—all of the holes depicted in the patent are on the back and bottom, and a streaming box certainly wouldn’t have needed the same cooling capacity as the AMD-designed CPU and GPU in the Series S.
The console also would have been square-shaped and considerably smaller than a Series S—not quite as small as a dedicated video-streaming box like an Apple TV or Roku Ultra, but not too far off either (the patent document doesn’t list dimensions, but we’ve done a rough size comparison using the HDMI and Ethernet ports on the Keystone box and an Apple TV 4K). The console’s controller sync button would have been mounted on its side, rather than in front, as it is on the Series S.

In the alternate reality of the FTC v. Microsoft slide deck, all of these new consoles and the new controller would have been announced or launched by now. But as Microsoft Gaming CEO Phil Spencer said shortly after those documents leaked, the company’s plans have changed substantially in the interim. A disc-less version of the Series X is coming, but it looks exactly like the current version of the console without a disc drive; Microsoft is also pursuing a strategy where it takes more of its internally developed games multi-platform, rather than restricting them to the Xbox and to Windows PCs. These moves are at least partially in response to sliding revenue from Microsoft’s console business, which has seen its revenue decline by double digits year over year for the last couple of years.
Neither Spencer nor Microsoft has ever said never about the Keystone console, leaving the door open to an eventual release if and when the price of manufacturing the console comes down. In the meantime, the streaming-only Xbox lives on as an app for newer Samsung smart TVs.
Enlarge/ A Diamond Shruumz chocolate bar, which comes in a variety of flavors.
The US Food and Drug Administration has identified a synthetic psychedelic compound as well as compounds from a potentially toxic plant in the Diamond Shruumz-brand microdosing candies linked to a growing number of severe illnesses nationwide that have included seizures, intubation, and admissions to intensive care units.
It remains unclear what is in the candies and what may be causing the severe illnesses. Diamond Shruumz does not provide a full list of ingredients. The term “microdosing” and other marketing used by Diamond Shruumz suggests the candies contain a psychedelic compound, but the company does not name any. To figure it out, the FDA has been analyzing multiple samples of Diamond Shruumz-brand candies, including chocolates, gummies, and candy cones. On Tuesday, the FDA reported finding the synthetic psychedelic compound 4-AcO-DMT in the company’s Dark Chocolate Bar and its Birthday Cake Chocolate Bar.
As Ars reported previously, 4-AcO-DMT (aka 4- acetoxy-N,N-dimethyltryptamine, O-acetylpsilocin, or psilacetin) is a common synthetic tryptamine used in psychedelics and was previously suspected to be in the Diamond Shruumz candies. The psychoactive drug has a chemical structure similar to the most notable mushroom-derived psychedelic, psilocybin, as well as LSD. Though safety data on the compound is scant, it is not known to be linked to some of the severe symptoms seen in the current string of illnesses. People who use 4-Aco-DMT describe it as producing effects similar to psilocybin, but without some of the unpleasant side effects noted with natural mushrooms, such as nausea. Still, according to the CDC, some people who use it could experience nausea, vomiting, fast heart rate, anxiety, agitation, lightheadedness, or tremor.
Additionally, the FDA found three compounds from the Kava plant (Piper methysticum) in the company’s dark chocolate bar, though not the birthday-cake flavored bar. The compounds are kavalactones—desmethoxyyangonin, dihydrokavain, and kavain.
Concerning kava
Kava is a plant found on some Pacific Islands and is used in traditional herbal remedies for the treatment of anxiety, insomnia, stress, and other ailments. But, over the years, it has also occasionally been linked to severe liver toxicity. In the early 2000s, this led to warnings, withdrawals, and even bans in several countries, including Germany, Switzerland, France, Canada, and the UK. In 2002, the FDA issued an advisory of its own over the associated liver injuries, which include hepatitis, cirrhosis, and liver failure. Later that same year, researchers published case reports of 11 people (two in the US and nine in Europe) who developed liver failure after using kava products and needed subsequent liver transplants.
In an update on the illnesses linked to Diamond Shruumz candies, the CDC noted that kava can cause numbness of the mouth and skin, loss of coordination, dizziness, sedation, and gastrointestinal effects, such as nausea and vomiting. Consuming kava products alongside alcohol or drugs like benzodiazepines (e.g. Valium and Xanax) can heighten the sedative effects. But, the CDC seemed to downplay the risk of liver toxicity here, noting that it has only occasionally been associated with chronic or heavy ingestion of kava.
In all, it’s still unclear if the compounds the FDA identified in the Diamond Shruumz chocolate bars so far can explain the illnesses seen in the linked cases. The CDC lists the severe and common symptoms from those cases as including seizures, decreased level of consciousness, respiratory failure, nausea, vomiting, abdominal pain, hallucinations, uncontrolled movements, abnormal heart rate (e.g., too fast or too slow), high or low blood pressure, excessive sweating or secretions, and flushed skin.
The FDA said testing of other Diamond Shruumz products is still in progress. The agency noted that there can be differences across products and batches. In the meantime, the agency advises consumers not to eat, sell, or serve any of the company’s products and, instead, discard them.
There is still no recall of the candies. Diamond Shruumz has not responded to multiple inquiries from Ars. The FDA said Tuesday that the agency has “been in contact with the firm about a possible voluntary recall,” but to date, Diamond Shruumz has not initiated one.

While CRISPR is probably the most prominent gene-editing technology, there are a variety of others, some developed before, others since. And people have been developing CRISPR variants to perform more specialized functions, like altering specific bases. In all of these cases, researchers are trying to balance a number of competing factors: convenience; flexibility; specificity and precision for the editing; low error rates; and so on.
So, having additional options for editing can be a good thing, enabling new ways of balancing those different needs. On Wednesday, a pair of papers in Nature describe a DNA-based parasite that moves itself around bacterial genomes through a mechanism that hasn’t been previously described. It’s nowhere near ready for use in humans, but it may have some distinctive features that make it worth further development.
Going mobile
Mobile genetic elements, commonly called transposons, are quite common in many species—they make up nearly half the sequences in the human genome, for example. They are indeed mobile, showing up in new locations throughout the genome, sometimes by cutting themselves out and hopping to new locations, other times by sending a copy out to a new place in the genome. For any of this to work, they need to have an enzyme that cuts DNA and specifically recognizes the right transposon sequence to insert into the cut.
The specificity of that interaction, needed to ensure the system only inserts new copies of itself, and the cutting of DNA, are features we’d like for gene editing, which places a value on better understanding these systems.
Bacterial genomes tend to have very few transposons—the extra DNA isn’t really in keeping with the bacterial reproduction approach of “copy all the DNA as quickly as possible when there’s food around.” Yet bacterial transposons do exist, and a team of scientists based in the US and Japan identified one with a rather unusual feature. As an intermediate step in moving to a new location, the two ends of the transposon (called IS110) are linked together to form a circular piece of DNA.
In its circular form, the DNA sequences at the junction act as a signal that tells the cell to make an RNA copy of nearby DNA (termed a “promoter”). When linear, each of the two bits of DNA on either side of the junction lacks the ability to act as a signal; it only works when the transposon is circular. And the researchers confirmed that there is in fact an RNA produced by the circular form, although the RNA does not encode for any proteins.
So, the research team looked at over 100 different relatives of IS110 and found that they could all produce similar non-protein-coding RNAs, all of which shared some key features. These included stretches where nearby sections of the RNA could base-pair with each other, leaving an unpaired loop of RNA in between. Two of these loops contained sequences that either base-paired with the transposon itself or at the sites in the E. coli genome where it inserted.
That suggests that the RNA produced by the circular form of the transposon helped to act as a guide, ensuring that the transposon’s DNA was specifically used and only inserted into precise locations in the genome.
Editing without precision
To confirm this was right, the researchers developed a system where the transposon would produce a fluorescent protein when it was properly inserted into the genome. They used this to show that mutations in the loop that recognized the transposon would stop it from being inserted into the genome—and that it was possible to direct it to new locations in the genome by changing the recognition sequences in the second loop.
To show this was potentially useful for gene editing, the researchers blocked the production of the transposon’s own RNA and fed it a replacement RNA that worked. So, you could potentially use this system to insert arbitrary DNA sequences into arbitrary locations in a genome. It could also be used with targeting RNAs that caused specific DNA sequences to be deleted. All of this is potentially very useful for gene editing.
Emphasis on “potentially.” The problem is that the targeting sequences in the loops are quite short, with the insertion site targeted by a recognition sequence that’s only four to seven bases long. At the short end of this range, you’d expect that a random string of bases would have an insertion site about once every 250 bases.
That relatively low specificity showed. At the high end, various experiments could see an insertion accuracy ranging from a close-to-being-useful 94 percent down to a positively threatening 50 percent. For deletion experiments, the low end of the range was a catastrophic 32 percent accuracy. So, while this has some features of an interesting gene-editing system, there’s a lot of work to do before it could fulfill that potential. It’s possible that these recognition loops could be made longer to add the sort of specificity that would be needed for editing vertebrate genomes, but we simply don’t know at this point.

There was a panel discussion at a space conference in Singapore 11 years ago that has since become legendary in certain corners of the space industry for what it reveals about European attitudes toward upstart SpaceX.
The panel included representatives from a handful of launch enterprises, including Europe-based Arianespace, and the US launch company SpaceX. At one point during the discussion, the host asked the Arianespace representative—its chief of sales in Southeast Asia, Richard Bowles—how the institutional European company would respond to SpaceX’s promise of lower launch costs and reuse with the Falcon 9 rocket.
“What I’m discovering in the market is that SpaceX primarily seems to be selling a dream, which is good. We should all dream,” Bowles replied. “I think a $5 million launch or a $15 million launch is a bit of a dream. Personally, I think reusability is a dream. How am I going to respond to a dream? My answer to respond to a dream is, first of all, you don’t wake people up.”
To be fair to Bowles, at the time of his remarks, SpaceX had only launched the Falcon 9 five times by the middle of 2013. But his condescension was nevertheless something to behold.
Later in the discussion, Bowles added that he did not believe launching 100 times a year, something that SpaceX was starting to talk about, was “realistic.” Then, in a moment of high paternalism, he turned to the SpaceX official on the panel and said, “You shouldn’t present things that are not realistic.”
In response, Barry Matsumori, a senior vice president at SpaceX, calmly said he would let his company’s response come through its actions.
Actions do speak louder than words
Eleven years later, of course, SpaceX is launching more than 100 times a year. The company’s internal price for launching a Falcon 9 is significantly less than $20 million. And all of this is possible through the reuse of the rocket’s first stage and payload fairings, each of which have now proven capable of flying 20 or more times.
One might think that, in the decade since, European launch officials would have learned their lesson. After all, last year, the continent had to resort to launching its valuable Euclid Space Telescope on a Falcon 9 rocket. This year, because the new European Ariane 6 rocket was not yet ready after myriad delays, multiple Galileo satellites have been launched and will be launched on the Falcon 9 rocket.
Some officials have taken note. In a candid commentary last year, European Space Agency chief Josef Aschbacher acknowledged that the continent faced an “acute” launcher crisis amid the Ariane 6 delays and the rise of SpaceX as a launch competitor. “SpaceX has undeniably changed the launcher market paradigm as we know it,” Aschbacher wrote. “With the dependable reliability of Falcon 9 and the captivating prospects of Starship, SpaceX continues to totally redefine the world’s access to space, pushing the boundaries of possibility as they go along.”
But not everyone got the message, it seems.
Next month, the Ariane 6 rocket should finally make its debut. It will probably be successful. Europe has excellent technical capabilities in regard to launch. But from day one, the Ariane 6 launch vehicle will cost significantly more than the Falcon 9 rocket, which has similar capabilities, and offer no provision for reuse. Certainly, it will meet Europe’s institutional needs. But it likely will not shake up the market, nor realistically compete with a fully reusable Falcon 9.
Who really needs to be woken up?
And what about Starship? If and when SpaceX can deliver it to the market, the next-generation rocket will offer a fully reusable booster with five times the lift capacity of the Ariane 6 rocket for half its cost or less. How can Europe hope to compete with that? The European Space Agency’s director of space transportation, Toni Tolker-Nielsen—who works for Aschbacher, it should be noted—said he’s not concerned.
“Honestly, I don’t think Starship will be a game-changer or a real competitor,” he said in an interview with Space News. “This huge launcher is designed to fly people to the Moon and Mars. Ariane 6 is perfect for the job if you need to launch a four- or five-ton satellite. Starship will not eradicate Ariane 6 at all.”
In one sense, Tolker-Nielsen is correct. Starship will not change how Europe gets its small and medium-sized satellites into space. Made and launched in Europe, the Ariane 6 rocket will be a workhorse for the continent. Indeed, some European officials are going so far as to press for legislation mandating that European satellites launch on European rockets.
But to say Starship will not be a game-changer represents the same head-in-the-sand attitude displayed by Bowles a decade ago with his jokes about not waking the deluded dreamers up. In hindsight, it’s clear that the dreamers were not SpaceX or its customers. Rather, they were European officials who had lulled themselves into thinking their dominance in commercial launch would persist without innovation.
While they slumbered, these officials ignored the rise of reusability. They decided the Ariane 6 rocket should look like its expendable predecessors, with solid rocket boosters. Meanwhile, following the rise of the Falcon 9, nearly all new rocket projects have incorporated a significant reusability component. It’s no longer just SpaceX founder Elon Musk saying companies need to pursue reuse or perish. Almost everyone is.
Enlarge/ Painting of a gryphon, or griffin, a lion-raptor chimera from ancient folklore.
Mark Witton
The gryphon, or griffin, is a legendary creature dating back to classical antiquity, sporting the body, legs, and tail of a lion and the wings, head, and front talons of an eagle. Since the 1980s, a popular “geomyth” has spread that the griffin’s unique appearance was inspired by the fossilized skeleton of a horned dinosaur known as Protoceratops. It’s a fascinating and colorful story, but according to the authors of a new paper published in the journal Interdisciplinary Science Reviews, there is no hard evidence to support such a connection.
“Everything about griffin origins is consistent with their traditional interpretation as imaginary beasts, just as their appearance is entirely explained by them being [mythological] chimeras of big cats and raptorial birds,” said co-author Mark Witton, a paleontologist at the University of Portsmouth. “Invoking a role for dinosaurs in griffin lore, especially species from distant lands like Protoceratops, not only introduces unnecessary complexity and inconsistencies to their origins, but also relies on interpretations and proposals that don’t withstand scrutiny.”
There are representations of griffin-like creatures in ancient Egyptian art dated to before 3000 BCE, while in ancient Greek and Roman texts the creatures were associated with gold deposits in Central Asia. By the Middle Ages, griffins were common figures in medieval iconography and in heraldry. The hippogriff named Buckbeak in Harry Potter and the Prisoner of Azkaban is a related mythical creature, the product of a griffin and a mare.
It was the legendary link to Central Asian gold deposits that intrigued classical folklorist Adrienne Mayor in the 1980s. Drawing on Greek and Latin texts and related artworks, she suggested (beginning with a 1989 paper in Cryptozoology) that nomadic prospectors stumbled across fossilized skeletons of Protoceratops and brought tales of strange beaked quadrupeds to other regions as they traveled southeast along ancient trade routes. The dinosaur’s bony neck frill might have been interpreted in early illustrations as mammal-like external ears, with its beak indicating a creature that was part-bird, leading to the eventual addition of wings.

Over the last 30 years, Mayor’s hypothesis has gained traction in the popular media and within certain academic circles; it’s now one of the most famous and widely touted examples of geomythology. It’s not an entirely crazy idea, even if its origins lie in the pseudoscientific field of cryptozoology. After all, people as far back as Paleolithic times certainly used fossils as decorative ornaments or talismans, and there are bona fide cases of such “geomyths”: For example, British ammonites were modified into “snake stones”; shark teeth were interpreted as snake tongues; and “winged” brachiopods became “stone swallows” in historic China.
The case for skepticism
But Witton and fellow Portsmouth paleontologist Richard Hing were skeptical because of the lack of any material evidence to support the connection between the griffin and Protoceratops. And they weren’t alone. Paleontologist Paul Sereno once dismissed Mayor’s claims as “sophomoric” and questioned her understanding of how fossils are found, identified, and interpreted, per the authors. So they set out to conduct the first detailed assessment of Mayor’s claims, re-examining historical fossil records—including the distribution of sites where Protoceratops fossils have been found—and classical sources, as well as consulting with historians and archaeologists about the supposed link.
“It is important to distinguish between fossil folklore with a factual basis—that is, connections between fossils and myth evidenced by archaeological discoveries or compelling references in literature and artwork—and speculated connections based on intuition,” said Hing. “There is nothing inherently wrong with the idea that ancient peoples found dinosaur bones and incorporated them into their mythology, but we need to root such proposals in realities of history, geography, and palaeontology. Otherwise, they are just speculation.”
Artificial intelligence-generated “deepfakes” that impersonate politicians and celebrities are far more prevalent than efforts to use AI to assist cyber attacks, according to the first research by Google’s DeepMind division into the most common malicious uses of the cutting-edge technology.
The study said the creation of realistic but fake images, video, and audio of people was almost twice as common as the next highest misuse of generative AI tools: the falsifying of information using text-based tools, such as chatbots, to generate misinformation to post online.
The most common goal of actors misusing generative AI was to shape or influence public opinion, the analysis, conducted with the search group’s research and development unit Jigsaw, found. That accounted for 27 percent of uses, feeding into fears over how deepfakes might influence elections globally this year.
Deepfakes of UK Prime Minister Rishi Sunak, as well as other global leaders, have appeared on TikTok, X, and Instagram in recent months. UK voters go to the polls next week in a general election.
Concern is widespread that, despite social media platforms’ efforts to label or remove such content, audiences may not recognize these as fake, and dissemination of the content could sway voters.
Ardi Janjeva, research associate at The Alan Turing Institute, called “especially pertinent” the paper’s finding that the contamination of publicly accessible information with AI-generated content could “distort our collective understanding of sociopolitical reality.”
Janjeva added: “Even if we are uncertain about the impact that deepfakes have on voting behavior, this distortion may be harder to spot in the immediate term and poses long-term risks to our democracies.”
The study is the first of its kind by DeepMind, Google’s AI unit led by Sir Demis Hassabis, and is an attempt to quantify the risks from the use of generative AI tools, which the world’s biggest technology companies have rushed out to the public in search of huge profits.
As generative products such as OpenAI’s ChatGPT and Google’s Gemini become more widely used, AI companies are beginning to monitor the flood of misinformation and other potentially harmful or unethical content created by their tools.
In May, OpenAI released research revealing operations linked to Russia, China, Iran, and Israel had been using its tools to create and spread disinformation.
“There had been a lot of understandable concern around quite sophisticated cyber attacks facilitated by these tools,” said Nahema Marchal, lead author of the study and researcher at Google DeepMind. “Whereas what we saw were fairly common misuses of GenAI [such as deepfakes that] might go under the radar a little bit more.”
Google DeepMind and Jigsaw’s researchers analyzed around 200 observed incidents of misuse between January 2023 and March 2024, taken from social media platforms X and Reddit, as well as online blogs and media reports of misuse.

The second most common motivation behind misuse was to make money, whether offering services to create deepfakes, including generating naked depictions of real people, or using generative AI to create swaths of content, such as fake news articles.
The research found that most incidents use easily accessible tools, “requiring minimal technical expertise,” meaning more bad actors can misuse generative AI.
Google DeepMind’s research will influence how it improves its evaluations to test models for safety, and it hopes it will also affect how its competitors and other stakeholders view how “harms are manifesting.”
One of Windows 11’s more contentious changes is that, by default, both the Home and Pro editions of the operating system require users to sign in with a Microsoft account during setup. Signing in with an account does get you some benefits, at least if you’re a regular user of other Microsoft products like OneDrive, GamePass, or Microsoft 365 (aka Office). But if you don’t use those services, a lot of what a Microsoft account gets you in Windows 11 is repeated ads and reminders about signing up for those services. Using Windows with a traditional local account is still extremely possible, but it does require a small amount of know-how beyond just clicking the right buttons.
On the know-how front, Microsoft has taken one more minor, but nevertheless irritating, step away from allowing users to sign in with local accounts. This official Microsoft support page walks users with local accounts through the process of signing in to a Microsoft account. As recently as June 12, that page also included instructions for converting a Microsoft account into a local account. But according to Tom’s Hardware and the Internet Wayback Machine, those instructions disappeared on or around June 17 and haven’t been seen since.
Despite the documentation change, most of the workarounds for creating a local account still work in both Windows 11 23H2 (the publicly available version of Windows 11 for most PCs) and 24H2 (available now on Copilot+ PCs, later this fall for everyone else). The easiest way to do it on a PC you just took out of the box is to press Shift+F10 during the setup process to bring up a command prompt window, typing OOBEBYPASSNRO, rebooting, and then clicking the “I don’t have Internet” button when asked to connect to a Wi-Fi network.
Other workarounds include using the Rufus tool to create a USB installer that will automatically bypass the Microsoft account sign-in requirement, or (for Windows 11 Pro users) indicating that you want to join the PC to a corporate domain and then not actually joining it to a domain. Setting the PC up with a Microsoft account and then signing out afterward is also still an option.
There is one workaround that has allegedly stopped working—it used to be that trying to “sign in” with a nonexistent email account would get you a local sign-in option. But as of earlier this month, according to Windows Central editor Zac Bowden, it looks like the Windows 11 setup screen will just ask you to try another email address instead.
To be fair to Microsoft, all the big tech companies want you to sign in with an account before you can use all the features of the software, but neither Apple nor Google goes as far as to mandate account sign-in to access basic functionality. Macs, iPhones, and iPads will all let you complete the setup process without signing in, though you do have to know which buttons to click. Google will allow you to use Chromebooks in guest mode, and Android phones and tablets are still usable without signing in (though this does make it more difficult to find and install apps). Microsoft’s pushiness remains unique; there’s definitely a difference between a company that would really prefer that you sign in, and one that forces you to.
Linux and its code are made by people, and people are not with us forever. Over the weekend, a brief message on the Linux kernel mailing list reminded people of just how much one person can mean to a seemingly gargantuan project like Linux, and how quickly they can disappear:
Denise Finger, wife of the deceased, wrote to the Linux Wireless list on Friday evening:
This is to notify you that Larry Finger, one of your developers, passed away on June 21st.
LWN.net reckons that Finger, 84, contributed to 94 Linux kernel releases, or 1,464 commits total, at least since kernel 2.6.16 in 2006 (and when the kernel started using git to track changes). Given the sometimes precarious nature of contributing to the kernel, this is on its own an impressive achievement—especially for someone with no formal computer training, and who considered himself a scientist.
The deepest of trenches: Linux Wi-Fi in the 2000s
That kind of effort is worth celebrating, regardless. But it’s the space that Finger devoted himself to that makes him a notably patient, productive contributor.
Getting Wi-Fi to work on a device running Linux back when Finger started contributing was awful. The chances of your hardware being recognized, activated, and working properly right after install was akin to getting a straight flush in poker. If nobody had gotten around to your wireless chipset yet, you used NDISwrapper, a Windows-interfacing kludge tool that simultaneously made your Linux install less open and yet still painful to install and maintain.
Finger started fixing this with work on Broadcom’s BCM43XX drivers. Broadcom provided no code for its gear, so Finger helped reverse-engineer the necessary specs by manually dumping and reading hardware registers. Along with Broadcom drivers, Finger also provided Realtek drivers. Many commenters across blogs and message boards are noting that their systems are still using pieces of Finger’s code today.
Fixing mainframes, science gear, and RV resorts
Larry Finger, and fish, from his Quora profile.
Quora
Finger doesn’t have a large footprint on the web, outside of his hundreds of kernel commits. He has a page for DRAWxtl, for producing crystal-structure drawings, on his personal domain, but not a general personal page. He sometimes answered Quora questions. He had a GitHub profile, showing more than 100 contributions to projects in 2024.
Perhaps the biggest insight into Finger found in one place is a three-part series for Linux Journal, “Linux in a Windows Workstation Environment,” written in 2005, when he was roughly 65. He summarizes his background: Fortran programmer in 1963, PDP-11 interfaces to scientific instruments in the 1970s, VAX-11/780 work in the early 1980s, and then Unix/Linux systems, until retiring from the Carnegie Institution for Science in Washington, DC, in 1999. The mineral Fingerite is named for Finger, whose work in crystallography took him on a fellowship to northern Bavaria, as noted in one Quora answer about the Autobahn.
“At that time, I became a full-time RV resident, dedicated to the avoidance of cold weather,” Finger writes. He and his wife Denise arrived that year at a 55-plus RV community in Mesa, Arizona. He joined the computer club, which had a growing number of Windows PCs sharing a DSL connection through one of the systems running WinGate. A new RV resort owner wanted to expand to 22 workstations, but WinGate licenses for that many would have been expensive for the club. Finger, who was “highly distrustful of using Windows 98 in a mission-critical role,” set to work.
Finger goes on across the series to describe the various ways he upgraded the routing and server capacity of the network, which grew to 38 user stations, Samba shares, a membership database, VPN tunnels, several free RJ-45 ports, and “free Wi-Fi access… throughout the park.”
Lots of people have commented on the broad work Finger did to make Linux usable for more people. A few mention that Finger also mentored people, the kind of work that has exponential effects. “MB” wrote on LWN.net that Finger “mentored other people to get the Broadcom Open Source code into kernel. And I think it was a huge success. And that was only a small part of Larry’s success story.”
In a 2023 Quora response to someone asking if someone without “any formal training in computer science” can “contribute something substantial” to Linux, Finger writes, “I think that I have.” Finger links to the stats for the 6.4 kernel, showing 172,346 lines of his code in it, roughly 0.5% of the total.
I have never taken any courses in Computer Science; however, I have considerable experience in coding, much of which happened when computers were a lot less powerful than today, and it was critical to write code that ran efficiently.
Finger suggests in his response small patches, deep reading of the guidelines, and always using git’s send-email to send patches: “Nothing will get shot down more quickly than a patch submitted from a mailer such as Thunderbird.” Finding typos and errors in comments and text strings can help, especially after translation. Finger advises being patient, expecting criticism about following rules and formats, and to keep plugging away at it.
In another Quora response about kernel driver development, Finger says, “This activity can be highly rewarding, and also equally frustrating!” You should learn C, Finger suggested, and maybe start with analyzing USB drivers, and take your time learning about DMA.
“Do not lose hope,” Finger wrote. “It took me about 2 years before I could do anything more than tell the experts where my system was generating a fault.”
Enlarge/ Microsoft’s 11th-edition Surface Pro, as exploded by iFixit. Despite adhesive holding in the screen and the fact that you need to remove the heatsink to get at the battery, it’s still much more repairable than past Surfaces or competing tablets.
For a long time, Microsoft’s Surface hardware was difficult-to-impossible to open and repair, and devices as recent as 2019’s Surface Pro 7 still managed a repairability score of just 1 out of 10 on iFixit’s scale. 2017’s original Surface Laptop needed to be physically sliced apart to access its internals, making it essentially impossible to try to fix the machine without destroying it.
Now, iFixit has torn apart the most recent Snapdragon X-powered Surface Pro and Surface Laptop devices and has mostly high praise for both devices in its preliminary teardown video. Both devices earn an 8 out of 10 on iFixit’s repairability scale, thanks to Microsoft’s first-party service manuals, the relative ease with which both devices can be opened, and clearly labeled internal components.
Beneath the Surface
To open the Surface Laptop, iFixit says you only need to undo four screws, hidden beneath the laptop’s rubber feet; at that point, the bottom of the machine is only attached by magnets, rather than breakable retention clips. Opening the bottom of the laptop provides easy access to the battery and an M.2 2232 SSD. Labels inside the device indicate which screws need to be removed to replace which parts, and what kind of screwdriver you’ll need to do the job; scannable barcodes also make it easier to find repair manuals and parts on Microsoft’s site. Most other parts are easy to remove and replace once the bottom of the laptop is off.
The Surface Pro’s best repairability feature remains its easily accessible M.2 2232 SSD, present under a pop-off cover on the back of the tablet. From there, things get more difficult—accessing the battery and other components requires removing the screen, which is still held in place with adhesive rather than screws or magnets. This adhesive needs to be removed—iFixit cut it away with a thin plastic tool, and closing the tablet back up securely would likely require new adhesive to be applied. Once inside, the parts and screws are still labeled clearly, but you do need to remove the entire heatsink before you can replace the battery.
iFixit uses slightly different criteria for evaluating the repairability of laptops and tablets since tablets are more tightly integrated devices. So despite the identical repairability scores, the Surface Pro remains slightly more difficult to open and fix than the laptop; iFixit is just comparing it to devices like the iPad Air and Pro rather than other PC laptops, and the Surface Pro still looks better than other tablets by comparison despite the use of adhesive.
The teardown video didn’t detail exactly why iFixit knocked points off of each device’s repairability score, though iFixit took note of the soldered-down non-upgradeable RAM and Wi-Fi/Bluetooth modules. Both devices also use way more screws and clips than something like the Framework Laptop, which could also be a factor.
We’ve been using the new Snapdragon-powered Surface devices for a few days now, and we’ll have more thoughts to share about the hardware and its performance in the coming days.
