In a vast stretch of the Sonoran Desert, between the towns of San Luis Río Colorado and Sonoyta in northern Mexico, sits a modest building of cement, galvanized sheet metal, and wood—the only stop along 125 miles of inhospitable landscape dominated by thorny ocotillo shrubs and towering saguaro cactuses up to 50 feet high. It’s a fonda—a small restaurant—called La Liebre del Desierto (The Desert Hare), and for more than 20 years, owner Elsa Ortiz Ramos has welcomed and nourished weary travelers taking a break from the adjacent highway that runs through the arid Pinacate and Grand Desierto de Altar Biosphere Reserve.

But the dedication and care of this petite woman go beyond her simple menu. Every two weeks, she pays out of pocket for a 5,000-gallon tank of water to distribute to a network of water troughs strategically placed in the area. By doing so, she relieves the thirst of bighorn sheep, ocelots, pronghorn, coyotes, deer, and even bats that have been deprived of access to their natural water sources.

“The crows come to the house and scream to warn us that there is no more water … it’s our alarm,” says Ortiz Ramos in her distinct northern Mexico accent. Her words sound straight from an Aesop’s fable, but they take on stark realism in this spot. Covering large parts of Arizona, California, and the Mexican states of Baja California and Sonora, the Sonoran Desert—along with the Lut Desert in Iran—was cataloged in 2023 as having the hottest surface temperature on the planet, at 80.8° Celsius (177° Fahrenheit).

Through narrow steel bollards 3.5 inches apart, I observe lush vegetation surrounding the Quitobaquito spring on the other side of the border. “This vital source supplies both humans and animals over an area of more than 1 million hectares,” Federico Godínez Leal, an agronomist from the University of Guadalajara, explains to me. But now this crucial water source is restricted to the US side due to the construction of the border wall, and I have come with him here to understand the consequences. Godínez Leal and his team have been documenting the stark difference between each side: Their poignant photographs show skeletons of wild boar, deer, and bighorn sheep lying on Mexican soil.

Between 2017 and 2021, the US government installed more than 450 miles of border barriers—steel structures between 18 and 29 feet high, spaced less than 4 inches apart—in the western end of the more than 1,900 miles of border between Mexico and the United States, stretching from the Pacific Ocean to the Gulf of Mexico. Of these 450 miles, 81 percent were replacements of existing vehicular or pedestrian barriers—but which, due to their design, allowed some passage of animals across the border. The rest were new barriers.

Before its construction, scientists on both sides of the border had warned about the impact that the wall could have on the animals of the area, and they are now working to understand the consequences. In turn, villagers in some spots on the Mexican side of the border have organized to try to alleviate the thirst of many animals that have been left without access to water.

Sole survivors —

The mammoths of Wrangel Island purged a lot of harmful mutations before dying off.

A small group of woolly mammoths became trapped on Wrangel Island around 10,000 years ago when rising sea levels separated the island from mainland Siberia. Small, isolated populations of animals lead to inbreeding and genetic defects, and it has long been thought that the Wrangel Island mammoths ultimately succumbed to this problem about 4,000 years ago.

A paper in Cell on Thursday, however, compared 50,000 years of genomes from mainland and isolated Wrangel Island mammoths and found that this was not the case. What the authors of the paper discovered not only challenges our understanding of this isolated group of mammoths and the evolution of small populations, it also has important implications for conservation efforts today.

A severe bottleneck

It’s the culmination of years of genetic sequencing by members of the international team behind this new paper. They studied 21 mammoth genomes—13 of which were newly sequenced by lead author Marianne Dehasque; others had been sequenced years prior by co-authors Patrícia Pečnerová, Foteini Kanellidou, and Héloïse Muller. The genomes were obtained from Siberian woolly mammoths (Mammuthus primigenius), both from the mainland and the island before and after it became isolated. The oldest genome was from a female Siberian mammoth who died about 52,300 years ago. The youngest were from Wrangel Island male mammoths who perished right around the time the last of these mammoths died out (one of them died just 4,333 years ago).

It’s a remarkable and revealing time span: The sample included mammoths from a population that started out large and genetically healthy, went through isolation, and eventually went extinct.

Mammoths, the team noted in their paper, experienced a “climatically turbulent period,” particularly during an episode of rapid warming called the Bølling-Allerød interstadial (approximately 14,700 to 12,900 years ago)—a time that others have suggested might have led to local woolly mammoth extinctions. However, the genomes of mammoths studied through this time period don’t indicate that the warming had any adverse effects.

Adverse effects only appeared—and drastically so—once the population was isolated on that island.

The team’s simulations indicate that, at its smallest, the total population of Wrangel Island mammoths was fewer than 10 individuals. This represents a severe population bottleneck. This was seen genetically through increased runs of homozygosity within the genome, caused when both parents contribute nearly identical chromosomes, both derived from a recent ancestor. The runs of homozygosity within isolated Wrangel Island mammoths were four times as great as those before sea levels rose.

Despite that dangerously tiny number of mammoths, they recovered. The population size, as well as inbreeding level and genetic diversity, remained stable for the next 6,000 years until their extinction. Unlike the initial population bottleneck, genomic signatures over time seem to indicate inbreeding eventually shifted to pairings of more distant relatives, suggesting either a larger mammoth population or a change in behavior.

Within 20 generations, their simulations indicate, the population size would have increased to about 200–300 mammoths. This is consistent with the slower decrease in heterozygosity that they found in the genome.

Long-lasting negative effects

The Wrangel Island mammoths may have survived despite the odds, and harmful genetic defects may not have been the reason for their extinction, but the research suggests their story is complicated.

At about 7,608 square kilometers today, a bit larger than the island of Crete, Wrangel Island would have offered a fair amount of space and resources, although these were large animals. For 6,000 years following their isolation, for example, they suffered from inbreeding depression, which refers to increased mortality as a result of inbreeding and its resulting defects.

That inbreeding also boosted the purging of harmful mutations. That may sound like a good thing—and it can be—but it typically occurs because individuals carrying two copies of harmful mutations die or fail to reproduce. So it’s good only if the population survives it.

The team’s results show that purging genetic mutations can be a lengthy evolutionary process. Lead author Marianne Dehasque is a paleogeneticist who completed her PhD at the Centre for Palaeogenetics. She explained to Ars that, “Purging harmful mutations for over 6,000 years basically indicates long-lasting negative effects caused by these extremely harmful mutations. Since purging in the Wrangel Island population went on for such a long time, it indicates that the population was experiencing negative effects from these mutations up until its extinction.”

brutal extortion —

More than a dozen men threatened, assaulted, tortured, or kidnapped 11 victims.

Cryptocurrency has always made a ripe target for theft—and not just hacking, but the old-fashioned, up-close-and-personal kind, too. Given that it can be irreversibly transferred in seconds with little more than a password, it’s perhaps no surprise that thieves have occasionally sought to steal crypto in home-invasion burglaries and even kidnappings. But rarely do those thieves leave a trail of violence in their wake as disturbing as that of one recent, ruthless, and particularly prolific gang of crypto extortionists.

The United States Justice Department earlier this week announced the conviction of Remy Ra St. Felix, a 24-year-old Florida man who led a group of men behind a violent crime spree designed to compel victims to hand over access to their cryptocurrency savings. That announcement and the criminal complaint laying out charges against St. Felix focused largely on a single theft of cryptocurrency from an elderly North Carolina couple, whose home St. Felix and one of his accomplices broke into before physically assaulting the two victims—both in their seventies—and forcing them to transfer more than $150,000 in bitcoin and ether to the thieves’ crypto wallets.

In fact, that six-figure sum appears to have been the gang’s only confirmed haul from its physical crypto thefts—although the burglars and their associates made millions in total, mostly through more traditional crypto hacking as well as stealing other assets. A deeper look into court documents from the St. Felix case, however, reveals that the relatively small profit St. Felix’s gang made from its burglaries doesn’t capture the full scope of the harm they inflicted: In total, those court filings and DOJ officials describe how more than a dozen convicted and alleged members of the crypto-focused gang broke into the homes of 11 victims, carrying out a brutal spree of armed robberies, death threats, beatings, torture sessions, and even one kidnapping in a campaign that spanned four US states.

In court documents, prosecutors say the men—working in pairs or small teams—threatened to cut toes or genitalia off of one victim, kidnapped and discussed killing another, and planned to threaten another victim’s child as leverage. Prosecutors also describe disturbing torture tactics: how the men inserted sharp objects under one victim’s fingernails and burned another with a hot iron, all in an effort to coerce their targets to hand over the devices and passwords necessary to transfer their crypto holdings.

“The victims in this case suffered a horrible, painful experience that no citizen should have to endure,” Sandra Hairston, a US attorney for the Middle District of North Carolina who prosecuted St. Felix’s case, wrote in the Justice Department’s announcement of St. Felix’s conviction. “The defendant and his coconspirators acted purely out of greed and callously terrorized those they targeted.”

The serial extortion spree is almost certainly the worst of its kind ever to be prosecuted in the US, says Jameson Lopp, the cofounder and chief security officer of Casa, a cryptocurrency-focused physical security firm, who has tracked physical attacks designed to steal cryptocurrency going back as far as 2014. “As far as I’m aware, this is the first case where it was confirmed that the same group of people went around and basically carried out home invasions on a variety of different victims,” Lopp says.

Lopp notes, nonetheless, that this kind of crime spree is more than a one-off. He has learned of other similar attempts at physical theft of cryptocurrency in just the past month that have escaped public reporting—he says the victims in those cases asked him not to share details—and suggests that in-person crypto extortion may be on the rise as thieves realize the attraction of crypto as a highly valuable and instantly transportable target for theft. “Crypto, as this highly liquid bearer asset, completely changes the incentives of doing something like a home invasion,” Lopp says, “or even kidnapping and extortion and ransom.”

ChatGPT outperforms undergrads in intro-level courses, falls short later

AI, college, exams, grades / /
Overhead view of a classroom full of students at desks, focused on writing on papers.

“Since the rise of large language models like ChatGPT there have been lots of anecdotal reports about students submitting AI-generated work as their exam assignments and getting good grades. So, we stress-tested our university’s examination system against AI cheating in a controlled experiment,” says Peter Scarfe, a researcher at the School of Psychology and Clinical Language Sciences at the University of Reading.

His team created over 30 fake psychology student accounts and used them to submit ChatGPT-4-produced answers to examination questions. The anecdotal reports were true—the AI use went largely undetected, and, on average, ChatGPT scored better than human students.

Rules of engagement

Scarfe’s team submitted AI-generated work in five undergraduate modules, covering classes needed during all three years of study for a bachelor’s degree in psychology. The assignments were either 200-word answers to short questions or more elaborate essays, roughly 1,500 words long. “The markers of the exams didn’t know about the experiment. In a way, participants in the study didn’t know they were participating in the study, but we’ve got necessary permissions to go ahead with that”, Scarfe claims.

Shorter submissions were prepared simply by copy-pasting the examination questions into ChatGPT-4 along with a prompt to keep the answer under 160 words. The essays were solicited the same way, but the required word count was increased to 2,000. Setting the limits this way, Scarfe’s team could get ChatGPT-4 to produce content close enough to the required length. “The idea was to submit those answers without any editing at all, apart from the essays, where we applied minimal formatting,” says Scarfe.

Overall, Scarfe and his colleagues slipped 63 AI-generated submissions into the examination system. Even with no editing or efforts to hide the AI usage, 94 percent of those went undetected, and nearly 84 percent got better grades (roughly half a grade better) than a randomly selected group of students who took the same exam.

“We did a series of debriefing meetings with people marking those exams and they were quite surprised,” says Scarfe. Part of the reason they were surprised was that most of those AI submissions that were detected did not end up flagged because they were too repetitive or robotic—they got flagged because they were too good.

Which raises a question: What do we do about it?

AI-hunting software

“During this study we did a lot of research into techniques of detecting AI-generated content,” Scarfe says. One such tool is Open AI’s GPTZero; others include AI writing detection systems like the one made by Turnitin, a company specializing in delivering tools for detecting plagiarism.

“The issue with such tools is that they usually perform well in a lab, but their performance drops significantly in the real world,” Scarfe explained. Open AI claims the GPTZero can flag AI-generated text as “likely” AI 26 percent of the time, with a rather worrisome 9 percent false positive rate. Turnitin’s system, on the other hand, was advertised as detecting 97 percent of ChatGPT and GPT-3 authored writing in a lab with only one false positive in a hundred attempts. But, according to Scarfe’s team, the released beta version of this system performed significantly worse.

Microdosing candies finally recalled after psychoactive muscimol found

After weeks of reports of severe illnesses across the country, the maker of Diamond Shruumz microdosing chocolates, gummies, and candy cones has finally issued a recall. It covers all lots and all flavors of all the brand’s products.

The illnesses have been marked by several severe symptoms, which notably include seizures, loss of consciousness, and the need for intubation and intensive care. To date, there have been 39 people sickened, including 23 hospitalizations across 20 states, according to the Food and Drug Administration and the Centers for Disease Control and Prevention. The FDA first issued a warning on the brand’s chocolate bars on June 7, when there were reports of eight cases, including six hospitalizations, in four states.

Diamond Shruumz’s parent company, Prophet Premium Blends, said in the recall notice that it had received only two complaints about the products to date and, upon receiving those complaints, reviewed recent laboratory analyses (Certificates of Analysis) of its products. According to the company, those CoAs noted “higher than normal amounts of muscimol,” which is one of two key compounds found in hallucinogenic Amanita mushrooms. Muscimol “could be a potential cause of symptoms consistent with those observed in persons who became ill after eating Diamond Shruumz products,” the company said in the recall notice.

In a statement posted on Diamond Shruumz’s website, Prophet Premium Blends announced the recall and added that it has also ceased production and distribution of all of the brand’s products.

“Due to consumers becoming ill after consuming the entire chocolate bar and some products containing higher levels of Muscimol than normal, it is crucial that all of our consumers refrain from ingesting this product while we, alongside the FDA, continue our investigation as to what is the cause of the serious adverse effects,” Prophet Premium Blends wrote on its website.

Diamond Shruumz has not responded to multiple requests for comment from Ars. Prophet Premium Blends did not respond to a request for comment and a list of questions.

What’s normal?

It’s unclear what amounts of muscimol were found in the company’s products and which products were affected. While the company reported only “higher than normal” amounts, it’s also unclear what the “normal” amount is. Diamond Shruumz posts third-party lab reports on its website, most of which indicate that the products are tested for muscimol. For instance, the reports show muscimol testing for all flavors of Cones and Extreme Gummies. For the brand’s chocolate bars, which the FDA first linked to the illnesses, all the bars except for the dark chocolate flavor showed muscimol results. For the gummies, only the report for the Hawaiian Punch flavor shows muscimol results. Of all the reports that include results for muscimol, all indicate that the amounts are lower than the limit of quantitation, which suggests that they are not supposed to contain any amount of muscimol. All of the reports reviewed by Ars were dated at various times throughout 2023.

Muscimol, along with related ibotenic acid, are both key psychoactive components of some Amanita mushrooms. That includes the hallucinogenic toadstool mushroom A. muscaria var. muscaria, which is notable for its unique bright red-orange caps with white warts. Both muscimol and ibotenic acid resemble neurotransmitters, namely GABA and glutamate, respectively. Muscimol is associated with depression of the central nervous system, while Ibotenic acid is associated with excitation of the central nervous system.

Fuzzy findings

According to the recall notice, it’s possible that the muscimol could cause some of the symptoms in people sickened, which included seizures, agitation, involuntary muscle contractions, loss of consciousness, confusion, sleepiness, nausea and vomiting, abnormal heart rates, and hyper/hypotension. The FDA said in its own update that it was “evaluating this information.”

The agency had previously identified the undisclosed synthetic psychedelic compound 4-AcO-DMT in the company’s chocolates, as well as undisclosed compounds found in a potentially toxic Kava plant (Piper methysticum). It remains unclear if any of those compounds explain the illnesses.

The totality of the ingredients in Diamond Shruumz’s products remains unclear. The company does not list the ingredients on its website, selling the products only with terms indicating they contain psychedelic compounds and the vague, buzzword-loaded description of having a “primo proprietary blend of nootropic and functional mushrooms.”

The CDC warns that such “edibles” are often sold as candies and snack food and might contain undisclosed ingredients, including illicit substances, adulterants, or potentially harmful contaminants. Common marketing terms to look out for include “microdosing,” “adaptogens,” “nootropics,” and “functional mushrooms,” the CDC warns.

Consumers should not eat, sell, or serve any Diamond Shruumz product. For those who have already purchased the products, they can be returned for a full refund to 1019 Arlington St., Orlando, Florida, 32805, according to Diamond Shruumz’s website.

Deciding “the future of books” —

Appeals court decision potentially reversing publishers’ suit may come this fall.

Appeals court seems lost on how Internet Archive harms publishers

The Internet Archive (IA) went before a three-judge panel Friday to defend its open library’s controlled digital lending (CDL) practices after book publishers last year won a lawsuit claiming that the archive’s lending violated copyright law.

In the weeks ahead of IA’s efforts to appeal that ruling, IA was forced to remove 500,000 books from its collection, shocking users. In an open letter to publishers, more than 30,000 readers, researchers, and authors begged for access to the books to be restored in the open library, claiming the takedowns dealt “a serious blow to lower-income families, people with disabilities, rural communities, and LGBTQ+ people, among many others,” who may not have access to a local library or feel “safe accessing the information they need in public.”

During a press briefing following arguments in court Friday, IA founder Brewster Kahle said that “those voices weren’t being heard.” Judges appeared primarily focused on understanding how IA’s digital lending potentially hurts publishers’ profits in the ebook licensing market, rather than on how publishers’ costly ebook licensing potentially harms readers.

However, lawyers representing IA—Joseph C. Gratz, from the law firm Morrison Foerster, and Corynne McSherry, from the nonprofit Electronic Frontier Foundation—confirmed that judges were highly engaged by IA’s defense. Arguments that were initially scheduled to last only 20 minutes stretched on instead for an hour and a half. Ultimately, judges decided not to rule from the bench, with a decision expected in the coming months or potentially next year. McSherry said the judges’ engagement showed that the judges “get it” and won’t make the decision without careful consideration of both sides.

“They understand this is an important decision,” McSherry said. “They understand that there are real consequences here for real people. And they are taking their job very, very seriously. And I think that’s the best that we can hope for, really.”

On the other side, the Association of American Publishers (AAP), the trade organization behind the lawsuit, provided little insight into how the day went. When reached for comment, AAP simply said, “We thought it was a strong day in court, and we look forward to the opinion.”

Decision could come early fall

According to Gratz, most of the questions for IA focused on “how to think about the situation where a particular book is available” from the open library and also available as an ebook that a library can license. Judges said they did not know how to think about “a situation where the publishers just haven’t come forward with any data showing that this has an impact,” Gratz said.

One audience member at the press briefing noted that instead judges were floating hypotheticals, like “if every single person in the world made a copy of a hypothetical thing, could hypothetically this affect the publishers’ revenue.”

McSherry said this was a common tactic when judges must weigh the facts while knowing that their decision will set an important precedent. However, IA has shown evidence, Gratz said, that even if IA provided limitless loans of digitized physical copies, “CDL doesn’t cause any economic harm to publishers, or authors,” and “there was absolutely no evidence of any harm of that kind that the publishers were able to bring forward.”

McSherry said that IA pushed back on claims that IA behaves like “pirates” when digitally lending books, with critics sometimes comparing the open library to illegal file-sharing networks. Instead, McSherry said that CDL provides a path to “meet readers where they are,” allowing IA to loan books that it owns to one user at a time no matter where in the world they are located.

“It’s not unlawful for a library to lend a book it owns to one patron at a time,” Gratz said IA told the court. “And the advent of digital technology doesn’t change that result. That’s lawful. And that’s what librarians do.”

In the open letter, IA fans pointed out that many IA readers were “in underserved communities where access is limited” to quality library resources. Being suddenly cut off from accessing nearly half a million books has “far-reaching implications,” they argued, removing access to otherwise inaccessible “research materials and literature that support their learning and academic growth.”

IA has argued that because copyright law is intended to provide equal access to knowledge, copyright law is better served by allowing IA’s lending than by preventing it. They’re hoping the judges will decide that CDL is fair use, reversing the lower court’s decision and restoring access to books recently removed from the open library. But Gratz said there’s no telling yet when that decision will come.

“There is no deadline for them to make a decision,” Gratz said, but it “probably won’t happen until early fall” at the earliest. After that, whichever side loses will have an opportunity to appeal the case, which has already stretched on for four years, to the Supreme Court. Since neither side seems prepared to back down, the Supreme Court eventually weighing in seems inevitable.

McSherry seemed optimistic that the judges at least understood the stakes for IA readers, noting that fair use is “designed to ensure that copyright actually serves the public interest,” not publishers’. Should the court decide otherwise, McSherry warned, the court risks allowing “a few powerful publishers” to “hijack the future of books.”

When IA first appealed, Kahle put out a statement saying IA couldn’t walk away from “a fight to keep library books available for those seeking truth in the digital age.”

“I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision.”

The flight hardware core stage for Europe’s new rocket, Ariane 6, is moved onto the launch pad for the first time. A launch is due to occur on July 9, 2024.

Enlarge / The flight hardware core stage for Europe’s new rocket, Ariane 6, is moved onto the launch pad for the first time. A launch is due to occur on July 9, 2024.

ESA-M. Pédoussaut

In a shocking announcement this week, the European intergovernmental organization responsible for launching and operating the continent’s weather satellites has pulled its next mission off a future launch of Europe’s new Ariane 6 rocket. Instead, the valuable MTG-S1 satellite will now reach geostationary orbit on SpaceX’s Falcon 9 rocket in 2025.

“This decision was driven by exceptional circumstances” said Phil Evans, director general of the organization Eumetsat. “It does not compromise our standard policy of supporting European partners, and we look forward to a successful SpaceX launch for this masterpiece of European technology.”

The decision, taken at a council meeting of Eumetsat’s 30 member nations on Wednesday and Thursday, comes less than two weeks before the debut of the Ariane 6 rocket, scheduled for July 9.

Stabbed in the back

Outwardly, at least, this decision reflects a lack of confidence in the reliability of the Ariane 6 rocket, the ability of European companies ArianeGroup and Arianespace to produce future versions of the Ariane 6, or both. It comes not just on the eve of the long-awaited debut of the Ariane 6, but also at a time when European officials are trying to close ranks and ensure that satellites built in Europe get launched on European rockets.

The retirement of the Ariane 5 rocket last July, and years of delays in the readiness for the Ariane 6 rocket, have led to a painful period in which European officials have had to come hat-in-hand to their longtime competitor and nemesis in the rocket industry, SpaceX, for launch services. As a result some of Europe’s most valuable missions, including the Euclid space telescope and several Galileo satellites, have already launched on the Falcon 9.

This has been embarrassing enough for European launch officials, who effectively created the concept of “commercial” space launch with the first Ariane rockets decades ago. For a long time, they, alongside Russia, were the kings of launching other people’s satellites. But now, on the eve of restoring European access to space, Eumetsat has effectively stabbed this industry in the back.

That is not too strong of language, either. In its release, Eumetsat described its new Meteosat Third Generation-Sounder 1 satellite as a “unique masterpiece of European technology.” The organization added, “This first European sounding satellite in a geostationary orbit will bring a revolution for weather forecasting and climate monitoring in Europe and Africa, and make it possible, for the first time, to observe the full lifecycle of a convective storm from space.” Critically, Eutmetsat was not willing to entrust this spacecraft to Europe’s new flagship rocket.

Philippe Baptiste, the chairman and chief executive of the French space agency CNES, certainly felt the sting, calling the decision a “brutal change” and saying it was a “disappointing day” for European space efforts.

“I am impatiently waiting to understand what reasons could have led Eumetsat to such a decision, at a time where all major European space countries as well as the European Commission are calling for launching European satellites on European launchers!” Baptiste wrote on LinkedIn. “Not mentioning the fact that we are 10 days away from the maiden flight of Ariane 6. How far will we, Europeans, go in our naivety?”

Why did they do this?

It is difficult to fully understand the motivations of Eumetsat in this decision. Most probably, there were some timing and reliability concerns. The MTG-S1 satellite was due to launch on the third flight of the Ariane 6 rocket, a mission nominally scheduled for early 2025. On this timeline the satellite very likely would have gotten to space more quickly than it otherwise would now on a Falcon 9.

However, because this 4-ton satellite is going to geostationary orbit, it would have been the first mission to require the use of a more powerful version of the Ariane 6 rocket. Instead of using two solid-rocket boosters, this “64” version of the rocket uses four solid-rocket boosters. It seems likely that Eumetsat officials had concerns that the timeline for this launch would drag out and perhaps some mission assurance concerns about being the first launch of an Ariane 64 rocket.

Whatever their reasons, the European satellite officials have thrown a massive turd into the punchbowl at festivities for the debut of the Ariane 6 rocket.

Tesla says Model 3 that burst into flames in fatal tree crash wasn’t defective

Tesla has denied that “any defect in the Autopilot system caused or contributed” to the 2022 death of a Tesla employee, Hans von Ohain, whose Tesla Model 3 burst into flames after the car suddenly veered off a road and crashed into a tree.

“Von Ohain fought to regain control of the vehicle, but, to his surprise and horror, his efforts were prevented by the vehicle’s Autopilot features, leaving him helpless and unable to steer back on course,” a wrongful death lawsuit filed in May by von Ohain’s wife, Nora Bass, alleged.

In Tesla’s response to the lawsuit filed Thursday, the carmaker also denied that the 2021 vehicle had any defects, contradicting Bass’ claims that Tesla knew that the car should have been recalled but chose to “prioritize profits over consumer safety.”

As detailed in her complaint, initially filed in a Colorado state court, Bass believes the Tesla Model 3 was defective in that it “did not perform as safely as an ordinary consumer would have expected it to perform” and “the benefits of the vehicle’s design did not outweigh the risks.”

Instead of acknowledging alleged defects and exploring alternative designs, Tesla marketed the car as being engineered “to be the safest” car “built to date,” Bass’ complaint said.

Von Ohain was particularly susceptible to this marketing, Bass has said, because he considered Tesla CEO Elon Musk to be a “brilliant man,” The Washington Post reported. “We knew the technology had to learn, and we were willing to be part of that,” Bass said, but the couple didn’t realize how allegedly dangerous it could be to help train “futuristic technology,” The Post reported.

In Tesla’s response, the carmaker defended its marketing of the Tesla Model 3, denying that the company “engaged in unfair and deceptive acts or practices.”

“The product in question was not defective or unreasonably dangerous,” Tesla’s filing said.

Insisting in its response that the vehicle was safe when it was sold, Tesla again disputed Bass’ complaint, which claimed that “at no time after the purchase of the 2021 Tesla Model 3 did any person alter, modify, or change any aspect or component of the vehicle’s design or manufacture.” Contradicting this, Tesla suggested that the car “may not have been in the same condition at the time of the crash as it was at the time when it left Tesla’s custody.”

The Washington Post broke the story about von Ohain’s fatal crash, reporting that it may be “the first documented fatality linked to the most advanced driver assistance technology offered” by Tesla. In response to Tesla’s filing, Bass’ attorney, Jonathan Michaels, told The Post that his team is “committed to advocating fiercely for the von Ohain family, ensuring they receive the justice they deserve.”

Michaels told The Post that perhaps as significant as alleged autonomous driving flaws, the Tesla Model 3 was also allegedly defective “because of the intensity of the fire that ensued after von Ohain hit the tree, which ultimately caused his death.” According to the Colorado police officer looking into the crash, Robert Madden, the vehicle fire was among “the most intense” he’d ever investigated, The Post reported.

Lawyers for Bass and Tesla did not immediately respond to Ars’ request for comment.

EU executive arm drops merger review into US tech companies’ alliance.

–

EU competition chief Margrethe Vestager said the bloc was looking into practices that could in effect lead to a company controlling a greater share of the AI market.

Enlarge / EU competition chief Margrethe Vestager said the bloc was looking into practices that could in effect lead to a company controlling a greater share of the AI market.

Brussels is preparing for an antitrust investigation into Microsoft’s $13 billion investment into OpenAI, after the European Union decided not to proceed with a merger review into the most powerful alliance in the artificial intelligence industry.

The European Commission, the EU’s executive arm, began to explore a review under merger control rules in January, but on Friday announced that it would not proceed due to a lack of evidence that Microsoft controls OpenAI.

However, the commission said it was now exploring the possibility of a traditional antitrust investigation into whether the tie-up between the world’s most valuable listed company and the best-funded AI start-up was harming competition in the fast-growing market.

The commission has also made inquiries about Google’s deal with Samsung to install a modified version of its Gemini AI system in the South Korean manufacturer’s smartphones, it revealed on Friday.

Margrethe Vestager, the bloc’s competition chief, said in a speech on Friday: “The key question was whether Microsoft had acquired control on a lasting basis over OpenAI. After a thorough review we concluded that such was not the case. So we are closing this chapter, but the story is not over.”

She said the EU had sent a new set of questions to understand whether “certain exclusivity clauses” in the agreement between Microsoft and OpenAI “could have a negative effect on competitors.” The move is seen as a key step toward a formal antitrust probe.

The bloc had already sent questions to Microsoft and other tech companies in March to determine whether market concentration in AI could potentially block new companies from entering the market, Vestager said.

Microsoft said: “We appreciate the European Commission’s thorough review and its conclusion that Microsoft’s investment and partnership with OpenAI does not give Microsoft control over the company.”

Brussels began examining Microsoft’s relationship with the ChatGPT maker after OpenAI’s board abruptly dismissed its chief executive Sam Altman in November 2023, only to be rehired a few days later. He briefly joined Microsoft as the head of a new AI research unit, highlighting the close relationship between the two companies.

Regulators in the US and UK are also scrutinizing the alliance. Microsoft is the biggest backer of OpenAI, although its investment of up to $13 billion, which was expanded in January 2023, does not involve acquiring conventional equity due to the startup’s unusual corporate structure. Microsoft has a minority interest in OpenAI’s commercial subsidiary, which is owned by a not-for-profit organization.

Antitrust investigations tend to last years, compared with a much shorter period for merger reviews, and they focus on conduct that could be undermining rivals. Companies that are eventually found to be breaking the law, for example by bundling products or blocking competitors from access to key technology, risk hefty fines and legal obligations to change their behavior.

Vestager said the EU was looking into practices that could in effect lead to a company controlling a greater share of the AI market. She pointed to a practice called “acqui-hires,” where a company buys another one mainly to get its talent. For example, Microsoft recently struck a deal to hire most of the top team from AI start-up Inflection, in which it had previously invested. Inflection remains an independent company, however, complicating any traditional merger investigation.

The EU’s competition chief said regulators were also looking into the way big tech companies may be preventing smaller AI models from reaching users.

“This is why we are also sending requests for information to better understand the effects of Google’s arrangement with Samsung to pre-install its small model ‘Gemini nano’ on certain Samsung devices,” said Vestager.

Jonathan Kanter, the top US antitrust enforcer, told the Financial Times earlier this month that he was also examining “monopoly choke points and the competitive landscape” in AI. The UK’s Competition and Markets Authority said in December that it had “decided to investigate” the Microsoft-OpenAI deal when it invited comments from customers and rivals.

Researchers craft smiling robot face from living human skin cells

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.

Shoji Takeuchi, Michio Kawai, Minghao Nie, and Haruka Oda authored the study, titled “Perforation-type anchors inspired by skin ligament for robotic face covered with living skin,” which is due for July publication in Cell Reports Physical Science. We learned of the study from a report published earlier this week by New Scientist.

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.

Shopping app Temu is “dangerous malware,” spying on your texts, lawsuit claims

“Cleverly hidden spyware” —

Temu “surprised” by the lawsuit, plans to “vigorously defend” itself.

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.”

AI voice clone will narrate daily Olympics video recaps; critics call it a “code-generated ghoul.”

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?

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.“
