In the hopes of dodging a significant projected worker shortage in the next few years, the Biden administration will finally start funding workforce development projects to support America’s ambitions to become the world’s leading chipmaker through historic CHIPS and Science Act investments.

The Workforce Partner Alliance (WFPA) will be established through the CHIPS Act’s first round of funding focused on workers, officials confirmed in a press release. The program is designed to “focus on closing workforce and skills gaps in the US for researchers, engineers, and technicians across semiconductor design, manufacturing, and production,” a program requirements page said.

Bloomberg reported that the US risks a technician shortage reaching 90,000 by 2030. This differs slightly from Natcast’s forecast, which found that out of “238,000 jobs the industry is projected to create by 2030,” the semiconductor industry “will be unable to fill more than 67,000.”

Whatever the industry demand will actually be, with a projected tens of thousands of jobs needing to be filled just as the country is hoping to produce more chips than ever, the Biden administration is hoping to quickly train enough workers to fill openings for “researchers, engineers, and technicians across semiconductor design, manufacturing, and production,” a WFPA site said.

To do this, a “wide range of workforce solution providers” are encouraged to submit “high-impact” WFPA project proposals that can be completed within two years, with total budgets of between $500,000 and $2 million per award, the press release said.

Examples of “evidence-based workforce development strategies and methodologies that may be considered for this program” include registered apprenticeship and pre-apprenticeship programs, colleges or universities offering semiconductor industry-relevant degrees, programs combining on-the-job training with effective education or mentorship, and “experiential learning opportunities such as co-ops, externships, internships, or capstone projects.” While programs supporting construction activities will not be considered, programs designed to “reduce barriers” to entry in the semiconductor industry can use funding to support workers’ training, such as for providing childcare or transportation for workers.

“Making investments in the US semiconductor workforce is an opportunity to serve underserved communities, to connect individuals to good-paying sustainable jobs across the country, and to develop a robust workforce ecosystem that supports an industry essential to the national and economic security of the US,” Natcast said.

Between four to 10 projects will be selected, providing opportunities for “established programs with a track record of success seeking to scale,” as well as for newer programs “that meet a previously unaddressed need, opportunity, or theory of change” to be launched or substantially expanded.

The deadline to apply for funding is July 26, which gives applicants less than one month to get their proposals together. Applicants must have a presence in the US but can include for-profit organizations, accredited education institutions, training programs, state and local government agencies, and nonprofit organizations, Natcast’s eligibility requirements said.

Natcast—the nonprofit entity created to operate the National Semiconductor Technology Center Consortium—will manage the WFPA. An FAQ will be provided soon, Natcast said, but in the meantime, the agency is giving a brief window to submit questions about the program. Curious applicants can send questions to [email protected] until 11: 59 pm ET on July 9.

Awardees will be notified by early fall, Natcast said.

Planning the future of US chip workforce

In Natcast’s press release, Deirdre Hanford, Natcast’s CEO, said that the WFPA will “accelerate progress in the US semiconductor industry by tackling its most critical challenges, including the need for a highly skilled workforce that can meet the evolving demands of the industry.”

And the senior manager of Natcast’s workforce development programs, Michael Barnes, said that the WFPA will be critical to accelerating the industry’s growth in the US.

“It is imperative that we develop a domestic semiconductor workforce ecosystem that can support the industry’s anticipated growth and strengthen American national security, economic prosperity, and global competitiveness,” Barnes said.

Alzheimer’s scientist indicted for allegedly falsifying data in $16M scheme

A federal grand jury has indicted an embattled Alzheimer’s researcher for allegedly falsifying data to fraudulently obtain $16 million in federal research funding from the National Institutes of Health for the development of a controversial Alzheimer’s drug and diagnostic test.

Hoau-Yan Wang, 67, a medical professor at the City University of New York, was a paid collaborator with the Austin, Texas-based pharmaceutical company Cassava Sciences. Wang’s research and publications provided scientific underpinnings for Cassava’s Alzheimer’s treatment, Simufilam, which is now in Phase III trials.

Simufilam is a small-molecule drug that Cassava claims can restore the structure and function of a scaffolding protein in the brain of people with Alzheimer’s, leading to slowed cognitive decline. But outside researchers have long expressed doubts and concerns about the research.

In 2023, Science magazine obtained a 50-page report from an internal investigation at CUNY that looked into 31 misconduct allegations made against Wang in 2021. According to the report, the investigating committee “found evidence highly suggestive of deliberate scientific misconduct by Wang for 14 of the 31 allegations,” the report states. The allegations largely centered around doctored and fabricated images from Western blotting, an analytical technique used to separate and detect proteins. However, the committee couldn’t conclusively prove the images were falsified “due to the failure of Dr. Wang to provide underlying, original data or research records and the low quality of the published images that had to be examined in their place.”

In all, the investigation “revealed long-standing and egregious misconduct in data management and record keeping by Dr. Wang,” and concluded that “the integrity of Dr. Wang’s work remains highly questionable.” The committee also concluded that Cassava’s lead scientist on its Alzheimer’s disease program, Lindsay Burns, who was a frequent co-author with Wang, also likely bears some responsibility for the misconduct.

In March 2022, five of Wang’s articles published in the journal PLOS One were retracted over integrity concerns with images in the papers. Other papers by Wang have also been retracted or had statements of concern attached to them. Further, in September 2022, the Food and Drug Administration conducted an inspection of the analytical work and techniques used by Wang to analyze blood and cerebrospinal fluid from patients in a simufilam trial. The investigation found a slew of egregious problems, which were laid out in a “damning” report obtained by Science.

In the indictment last week, federal authorities were explicit about the allegations, claiming that Wang falsified the results of his scientific research to NIH “by, among other things, manipulating data and images of Western blots to artificially add bands [which represent proteins], subtract bands, and change their relative thickness and/or darkness, and then drawing conclusions” based on those false results.

Wang is charged with one count of major fraud against the United States, two counts of wire fraud, and one count of false statements. If convicted, he faces a maximum penalty of 10 years in prison for the major fraud charge, 20 years in prison for each count of wire fraud, and five years in prison for the count of false statements, the Department of Justice said in an announcement.

In a statement posted to its website, Cassava acknowledged Wang’s indictment, calling him a “former” scientific adviser. The company also said that the grants central to the indictment were “related to the early development phases of the Company’s drug candidate and diagnostic test and how these were intended to work.” However, Cassava said that Wang “had no involvement in the Company’s Phase 3 clinical trials of simufilam.”

Those ongoing trials, which some have called to be halted, are estimated to include over 1,800 patients across several countries.

The telltale words that could identify generative AI text

Delving deep —

New paper counts “excess words” that started appearing more often in the post-LLM era.

Thus far, even AI companies have had trouble coming up with tools that can reliably detect when a piece of writing was generated using a large language model. Now, a group of researchers has established a novel method for estimating LLM usage across a large set of scientific writing by measuring which “excess words” started showing up much more frequently during the LLM era (i.e., 2023 and 2024). The results “suggest that at least 10% of 2024 abstracts were processed with LLMs,” according to the researchers.

In a pre-print paper posted earlier this month, four researchers from Germany’s University of Tubingen and Northwestern University said they were inspired by studies that measured the impact of the COVID-19 pandemic by looking at excess deaths compared to the recent past. By taking a similar look at “excess word usage” after LLM writing tools became widely available in late 2022, the researchers found that “the appearance of LLMs led to an abrupt increase in the frequency of certain style words” that was “unprecedented in both quality and quantity.”

Delving in

To measure these vocabulary changes, the researchers analyzed 14 million paper abstracts published on PubMed between 2010 and 2024, tracking the relative frequency of each word as it appeared across each year. They then compared the expected frequency of those words (based on the pre-2023 trendline) to the actual frequency of those words in abstracts from 2023 and 2024, when LLMs were in widespread use.

The results found a number of words that were extremely uncommon in these scientific abstracts before 2023 that suddenly surged in popularity after LLMs were introduced. The word “delves,” for instance, shows up in 25 times as many 2024 papers as the pre-LLM trend would expect; words like “showcasing” and “underscores” increased in usage by nine times as well. Other previously common words became notably more common in post-LLM abstracts: the frequency of “potential” increased 4.1 percentage points; “findings” by 2.7 percentage points; and “crucial” by 2.6 percentage points, for instance.

Some examples of words that saw their use increase (or decrease) substantially after LLMs were introduced (bottom three words shown for comparison).

Enlarge / Some examples of words that saw their use increase (or decrease) substantially after LLMs were introduced (bottom three words shown for comparison).

These kinds of changes in word use could happen independently of LLM usage, of course—the natural evolution of language means words sometimes go in and out of style. However, the researchers found that, in the pre-LLM era, such massive and sudden year-over-year increases were only seen for words related to major world health events: “ebola” in 2015; “zika” in 2017; and words like “coronavirus,” “lockdown” and “pandemic” in the 2020 to 2022 period.

In the post-LLM period, though, the researchers found hundreds of words with sudden, pronounced increases in scientific usage that had no common link to world events. In fact, while the excess words during the COVID pandemic were overwhelmingly nouns, the researchers found that the words with a post-LLM frequency bump were overwhelmingly “style words” like verbs, adjectives, and adverbs (a small sampling: “across, additionally, comprehensive, crucial, enhancing, exhibited, insights, notably, particularly, within”).

This isn’t a completely new finding—the increased prevalence of “delve” in scientific papers has been widely noted in the recent past, for instance. But previous studies generally relied on comparisons with “ground truth” human writing samples or lists of pre-defined LLM markers obtained from outside the study. Here, the pre-2023 set of abstracts acts as its own effective control group to show how vocabulary choice has changed overall in the post-LLM era.

An intricate interplay

By highlighting hundreds of so-called “marker words” that became significantly more common in the post-LLM era, the telltale signs of LLM use can sometimes be easy to pick out. Take this example abstract line called out by the researchers, with the marker words highlighted: “A comprehensive grasp of the intricate interplay between […] and […] is pivotal for effective therapeutic strategies.”

After doing some statistical measures of marker word appearance across individual papers, the researchers estimate that at least 10 percent of the post-2022 papers in the PubMed corpus were written with at least some LLM assistance. The number could be even higher, the researchers say, because their set could be missing LLM-assisted abstracts that don’t include any of the marker words they identified.

Before 2023, it took a major world event like the coronavirus pandemic to see large jumps in word usage like this.

Enlarge / Before 2023, it took a major world event like the coronavirus pandemic to see large jumps in word usage like this.

Those measured percentages can vary a lot across different subsets of papers, too. The researchers found that papers authored in countries like China, South Korea, and Taiwan showed LLM marker words 15 percent of the time, suggesting “LLMs might… help non-natives with editing English texts, which could justify their extensive use.” On the other hand, the researchers offer that native English speakers “may [just] be better at noticing and actively removing unnatural style words from LLM outputs,” thus hiding their LLM usage from this kind of analysis.

Detecting LLM use is important, the researchers note, because “LLMs are infamous for making up references, providing inaccurate summaries, and making false claims that sound authoritative and convincing.” But as knowledge of LLMs’ telltale marker words starts to spread, human editors may get better at taking those words out of generated text before it’s shared with the world.

Who knows, maybe future large language models will do this kind of frequency analysis themselves, lowering the weight of marker words to better mask their outputs as human-like. Before long, we may need to call in some Blade Runners to pick out the generative AI text hiding in our midst.

Nature interrupted: Impact of the US-Mexico border wall on wildlife

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.”

Mere days before its debut, the Ariane 6 rocket loses a key customer to SpaceX

Zut Alors! —

“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.
