Billions of years ago Mars "had a warm, habitable climate with liquid water in lakes and flowing rivers," writes Ars Technica. But "In order for Mars to be warm enough to host liquid water, there must have been a lot of carbon dioxide in the atmosphere," says Benjamin Tutolo, a researcher at the University of Calgary. "The question we've been asking for at least 30 years was where the record of all this carbon is." Tutolo led a new study of rock samples collected by the Curiosity rover that might have answered this question... Curiosity rover was called Mars Science Laboratory for a reason. It went to the red planet fitted with a suite of instruments, some of which even the newer Perseverance was lacking. These enabled it to analyze the collected Martian rocks on the spot and beam the results back to Earth. "To get the most bang for the buck, NASA decided to send it to the place on Mars called the Gale Crater, because it was the tallest stack of sediments on the planet," Tutolo says. The central peak of Gale Crater was about 5 kilometers tall, created by the ancient meteorite impact... The idea then was to climb up Mount Sharp and collect samples from later and later geological periods at increasing elevations, tracing the history of habitability and the great drying up of Mars. On the way, the carbon missed by the satellites was finally found... It turned out the samples contained roughly between 5 and 10 percent of siderite... The siderite found in the samples was also pure, which Tutolo thinks indicates it has formed through an evaporation process akin to what we see in evaporated lakes on Earth. This, in turn, was the first evidence we've found of the ancient Martian carbon cycle. "Now we have evidence that confirms the models," Tutolo claims. The carbon from the atmosphere was being sequestered in the rocks on Mars just as it is on Earth. The problem was, unlike on Earth, it couldn't get out of these rocks... A large portion of carbon that got trapped in Martian rocks stayed in those rocks forever, thinning out the atmosphere. "While it's likely the red planet had its own carbon cycle, it was an imperfect one that eventually turned it into the lifeless desert it is today," the article points out. But the study still doesn't entirely explain what warmed the atmosphere of Mars — or why Martian habitability "was seemingly intermittent and fluctuating".

For combining machine learning with astronomy, high school senior Matteo Paz won $250,000 in the Regeneron Science Talent Search, reports Smithsonian magazine: The young scientist's tool processed 200 billion data entries from NASA's now-retired Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) telescope. His model revealed 1.5 million previously unknown potential celestial bodies.... [H]e worked on an A.I. model that sorted through the raw data in search of tiny changes in infrared radiation, which could indicate the presence of variable objects. Working with a mentor at the Planet Finder Academy at Caltech, Paz eventually flagged 1.5 million potential new objects, accoridng to the article, including supernovas and black holes. And that mentor says other Caltech researchers are using Paz's catalog of potential variable objects to study binary star systems.

"Members of the CA/Browser Forum have voted to slash cert lifespans from the current one year to 47 days," reports Computerworld, "placing an added burden on enterprise IT staff who must ensure they are updated." In a move that will likely force IT to much more aggressively use web certificate automation services, the Certification Authority Browser Forum (CA/Browser Forum), a gathering of certificate issuers and suppliers of applications that use certificates, voted [last week] to radically slash the lifespan of the certificates that verify the ownership of sites. The approved changes, which passed overwhelmingly, will be phased in gradually through March 2029, when the certs will only last 47 days. This controversial change has been debated extensively for more than a year. The group's argument is that this will improve web security in various ways, but some have argued that the group's members have a strong alternative incentive, as they will be the ones earning more money due to this acceleration... Although the group voted overwhelmingly to approve the change, with zero "No" votes, not every member agreed with the decision; five members abstained... In roughly one year, on March 15, 2026, the "maximum TLS certificate lifespan shrinks to 200 days. This accommodates a six-month renewal cadence. The DCV reuse period reduces to 200 days," according to the passed ballot. The next year, on March 15, 2027, the "maximum TLS certificate lifespan shrinks to 100 days. This accommodates a three-month renewal cadence. The DCV reuse period reduces to 100 days." And on March 15, 2029, "maximum TLS certificate lifespan shrinks to 47 days. This accommodates a one-month renewal cadence. The DCV reuse period reduces to 10 days." The changes "were primarily pushed by Apple," according to the article, partly to allow more effective reactions to possible changes in cryptography. And Apple also wrote that the shift "reduces the risk of improper validation, the scope of improper validation perpetuation, and the opportunities for misissued certificates to negatively impact the ecosystem and its relying parties."

An anonymous reader shared this report from CNBC: Neurotech startup Precision Neuroscience on Thursday announced that a core component of its brain implant system has been approved by the U.S. Food and Drug Administration, a major win for the four-year-old company... The company's brain-computer interface will initially be used to help patients with severe paralysis restore functions such as speech and movement, according to its website. Only part of Precision's system was approved by the FDA on Thursday, but it marks the first full regulatory clearance granted to a company developing a wireless BCI, Precision said in a release. Other prominent startups in the space include Elon Musk's Neuralink, and Synchron, which is backed by Amazon founder Jeff Bezos and Microsoft co-founder Bill Gates.... The piece of Precision's system that the FDA approved is called the Layer 7 Cortical Interface. The microelectrode array is thinner than a human hair and resembles a piece of yellow scotch tape. Each array is made up of 1,024 electrodes that can record, monitor and stimulate electrical activity on the brain's surface. When it is placed on the brain, Precision says it can conform to the surface without damaging any tissue. The FDA authorized Layer 7 to be implanted in patients for up to 30 days, and Precision will be able to market the technology for use in clinical settings. This means surgeons will be able to use the array during procedures to map brain signals, for instance. It is not Precision's end goal for the technology, but it will help the company generate revenue in the near term. Precision's co-founder and chief science officer also helped co-found Musk's Neuralink in 2017 before departing the following year, according to the article. He nows says this regulatory clearance "will exponentially increase our access to diverse, high-quality data, which will help us to build BCI systems that work more effectively."

In NoSQL database news, Arch Linux "is the latest Linux distribution replacing its Redis packages with the Valkey fork," reports Phoronix. Valkey is backed by the Linux Foundation, Google, Amazon Web Services, and Oracle, which the article points out is due to Redis's decision last year to shift the upstream Redis license from a BSD 3-clause to RSALv2 and SSPLv1. Valkey is replacing Redis in the Arch Linux extra repository and after a two week period the Redis package will be moved out to AUR and receive no further updates. Users are encouraged to migrate to Valkey as soon as possible.

"Russia is automating the spread of false information to fool AI chatbots," reports the Washington Post. (When researchers checked 10 chatbots, a third of the responses repeated false pro-Russia messaging.) The Post argues that this tactic offers "a playbook to other bad actors on how to game AI to push content meant to inflame, influence and obfuscate instead of inform," and calls it "a fundamental weakness of the AI industry." Chatbot answers depend on the data fed into them. A guiding principle is that the more the chatbots read, the more informed their answers will be, which is why the industry is ravenous for content. But mass quantities of well-aimed chaff can skew the answers on specific topics. For Russia, that is the war in Ukraine. But for a politician, it could be an opponent; for a commercial firm, it could be a competitor. "Most chatbots struggle with disinformation," said Giada Pistilli, principal ethicist at open-source AI platform Hugging Face. "They have basic safeguards against harmful content but can't reliably spot sophisticated propaganda, [and] the problem gets worse with search-augmented systems that prioritize recent information." Early commercial attempts to manipulate chat results also are gathering steam, with some of the same digital marketers who once offered search engine optimization — or SEO — for higher Google rankings now trying to pump up mentions by AI chatbots through "generative engine optimization" — or GEO. Our current situation "plays into the hands of those with the most means and the most to gain: for now, experts say, that is national governments with expertise in spreading propaganda." Russia and, to a lesser extent, China have been exploiting that advantage by flooding the zone with fables. But anyone could do the same, burning up far fewer resources than previous troll farm operations... In a twist that befuddled researchers for a year, almost no human beings visit the sites, which are hard to browse or search. Instead, their content is aimed at crawlers, the software programs that scour the web and bring back content for search engines and large language models. While those AI ventures are trained on a variety of datasets, an increasing number are offering chatbots that search the current web. Those are more likely to pick up something false if it is recent, and even more so if hundreds of pages on the web are saying much the same thing... The gambit is even more effective because the Russian operation managed to get links to the Pravda network stories edited into Wikipedia pages and public Facebook group postings, probably with the help of human contractors. Many AI companies give special weight to Facebook and especially Wikipedia as accurate sources. (Wikipedia said this month that its bandwidth costs have soared 50 percent in just over a year, mostly because of AI crawlers....) Last month, other researchers set out to see whether the gambit was working. Finnish company Check First scoured Wikipedia and turned up nearly 2,000 hyperlinks on pages in 44 languages that pointed to 162 Pravda websites. It also found that some false information promoted by Pravda showed up in chatbot answers. "They do even better in such places as China," the article points out, "where traditional media is more tightly controlled and there are fewer sources for the bots." (The nonprofit American Sunlight Project calls the process "LLM grooming".) The article quotes a top Kremlin propagandist as bragging in January that "we can actually change worldwide AI."

Launched in 1958, the "awkward-looking" Vanguard-1 satellite ("the size of a grapefruit") is the oldest artificial object orbiting Earth. "A team of researchers and engineers want to retrieve the satellite for closer inspection and are currently working to find a way to bring Vanguard-1 home," writes Gizmodo: Other satellites of its time have reentered through Earth's atmosphere, burning up in a fiery death, but Vanguard-1 is still in orbit, silently zooming through the void of space... A team of researchers and engineers from Virginia-based consulting firm Booz Allen Hamilton have put together a proposal on how to retrieve the satellite from space, bringing it back to Earth to study how its equipment has fared over the years, according to a report by Space.com. The team's proposal is detailed in a study published in the Aerospace Research Center earlier this year... Considering how old Vanguard-1 is, the astronauts would need to handle it with care, according to the team behind the proposal. Before a retrieval attempt, the team suggests that a spacecraft be sent to rendezvous with the satellite to inspect its condition up-close. The engineers suggested partnering with a wealthy space enthusiast willing to fund the outer space venture, or using a SpaceX vehicle to bring the satellite home. Once it's brought back to Earth, experts would examine Vanguard-1 to assess its condition — whether it was struck by space debris, if it's still holding together, and how its time in orbit has affected the satellite. The satellite could then be placed at the Smithsonian for display as a sort of time capsule, a reminder of the history of spaceflight, the team suggests. "Future missions (space debris removal, materials capture for on-orbit manufacturing, and even deep space exploration) could build on techniques demonstrated in the retrieval of Vanguard 1," the paper read. "Retrieving Vanguard 1 would be a challenge, but an achievable and invaluable step forward for the entire U.S. space community." "The researchers suggest that the satellite can be placed in a lower orbit and snagged from space, or reeled into the International Space Station," according to the article. Space.com shares this assessment from Bill Raynor, the associate superintendent of the Naval Research Laboratory's spacecraft engineering division. "For material and radiation effects scientists and engineers, it would be an unprecedented opportunity for investigating the effects of long-term space environmental exposure."

"There has never been a consensus or a 'smoking gun' to explain what started the pandemic," writes ABC News. Yet the Associated Press reports that "A federal website that used to feature information on vaccines, testing and treatment for COVID-19 has been transformed into a page supporting the theory that the pandemic originated with a lab leak." (This despite the fact that "about 325 Americans have died from COVID per week on average over the past four weeks, according to the U.S. Centers for Disease Control and Prevention.") The covid.gov website shows a photo of President Donald Trump walking between the words "lab" and "leak" under a White House heading... The web page also accuses Dr. Anthony Fauci, the former director of the National Institute of Allergy and Infectious Diseases, of pushing a "preferred narrative" that COVID-19 originated in nature. The origins of COVID have never been proven. Scientists are unsure whether the virus jumped from an animal, as many other viruses have, or came from a laboratory accident. A U.S. intelligence analysis released in 2023 said there is insufficient evidence to prove either theory. "Many scientists think it's more likely the virus originated naturally in a wild animal and then spilled over into people in a wildlife market located in Wuhan," reports NPR. And even Jamie Metzl, a critic of the wildlife spillover theory, told NPR that while they appreciated "efforts to dig deeper... it would be a terrible shame if such efforts distracted from essential work to help prevent further infections and treat people suffering from COVID-19 and long COVID." (The federal website covidtests.gov now also redirects instead to the new page...) Some scientists were critical of the new site, which they say appears political in intent. "Every one of the five pieces of evidence supporting the lab leak hypothesis ... is factually incorrect, embellished, or presented in a misleading way," [wrote Angela Rasmussen, a virologist at the University of Saskatchewan in Canada]. "But making evidence-based arguments in good faith about the pandemic's origin is not the purpose of this document. This is pure propaganda, intended to justify the systematic devastation of the federal government, particularly programs devoted to public health and biomedical research," Rasmussen added. Other scientists said the web site doesn't follow the existing body of scientific evidence on the issue. That evidence does not support "any of the many, often contradictory, lab leak scenarios that have been proposed," Michael Worobey, an evolutionary biologist at the University of Arizona, in an email to NPR. He argued that the evidence is consistent with "the less flashy hypothesis that bringing live animals infected with pathogens with pandemic potential into the heart of one of the biggest cities in the world was how this pandemic started.... the next pathogen with pandemic potential will find us easy pickings if we don't appreciate how risky this sort of 'biosafety level zero' activity is."

An anonymous reader quotes a report from Reuters: Twenty-one humanoid robots joined thousands of runners at the Yizhuang half-marathon in Beijing on Saturday, the first time these machines have raced alongside humans over a 21-km (13-mile) course. The robots from Chinese manufacturers such as DroidVP and Noetix Robotics came in all shapes and sizes, some shorter than 120 cm (3.9 ft), others as tall as 1.8 m (5.9 ft). One company boasted that its robot looked almost human, with feminine features and the ability to wink and smile. Some firms tested their robots for weeks before the race. Beijing officials have described the event as more akin to a race car competition, given the need for engineering and navigation teams. "The robots are running very well, very stable ... I feel I'm witnessing the evolution of robots and AI," said spectator He Sishu, who works in artificial intelligence. The robots were accompanied by human trainers, some of whom had to physically support the machines during the race. A few of the robots wore running shoes, with one donning boxing gloves and another wearing a red headband with the words "Bound to Win" in Chinese. The winning robot was Tiangong Ultra, from the Beijing Innovation Center of Human Robotics, with a time of 2 hours and 40 minutes. The men's winner of the race had a time of 1 hour and 2 minutes. [...] Some robots, like Tiangong Ultra, completed the race, while others struggled from the beginning. One robot fell at the starting line and lay flat for a few minutes before getting up and taking off. One crashed into a railing after running a few metres, causing its human operator to fall over. You can watch a recording of the race in its entirety on YouTube.

About one sixth of global cropland is contaminated by toxic heavy metals, researchers have estimated, with as many as 1.4 billion people living in high-risk areas worldwide. From a report: Approximately 14 to 17% of cropland globally -- roughly 242m hectares -- is contaminated by at least one toxic metal such as arsenic, cadmium, cobalt, chromium, copper, nickel or lead, at levels that exceed agricultural and human health safety thresholds. The analysis, which was conducted by the American Association for the Advancement of Science (AAAS) and published in the journal Science, collected data from more than 1,000 regional studies across the globe, as well as using machine learning technology. Dr Liz Rylott, a senior lecturer in the department of biology at the University of York, who was not involved in the research, said: "These findings reveal the deeply worrying extent to which these natural poisons are polluting our soils, entering our food and water, and affecting our health and our environment. Often collectively called heavy metals, these elements cause a range of devastating health problems, including skin lesions, reduced nerve and organ functions, and cancers." Toxic metal pollution in soil originates from both natural and human activity. Contaminated soil causes significant risks to ecosystems and human health as well as reducing crop yields, jeopardising water quality and food safety owing to bioaccumulation in farm animals. Toxic metal contamination can persist for decades once pollution has been introduced into soil.

Researchers at UC Berkeley claim to have induced a previously unseen color by using lasers to stimulate only the M cones in the retina, creating a visual experience beyond the natural limits of human perception. Called olo, the color is described as a highly saturated blue-green but is only visible through direct retinal manipulation. The Guardian reports: "We predicted from the beginning that it would look like an unprecedented color signal but we didn't know what the brain would do with it," said Ren Ng, an electrical engineer at the University of California, Berkeley. "It was jaw-dropping. It's incredibly saturated." The researchers shared an image of a turquoise square to give a sense of the color, which they named olo, but stressed that the hue could only be experienced through laser manipulation of the retina. "There is no way to convey that color in an article or on a monitor," said Austin Roorda, a vision scientist on the team. "The whole point is that this is not the color we see, it's just not. The color we see is a version of it, but it absolutely pales by comparison with the experience of olo." The findings have been published in the journal Science Advances.

Longtime Slashdot reader hackingbear shares a report from Interesting Engineering: A research team at Fudan University in Shanghai, China has built the fastest semiconductor storage device ever reported, a nonvolatile flash memory dubbed "PoX" that programs a single bit in 400 picoseconds (0.0000000004 s) -- roughly 25 billion operations per second. Conventional static and dynamic RAM (SRAM, DRAM) write data in 1-10 nanoseconds but lose everything when power is cut while current flash chips typically need micro to milliseconds per write -- far too slow for modern AI accelerators that shunt terabytes of parameters in real time. The Fudan group, led by Prof. Zhou Peng at the State Key Laboratory of Integrated Chips and Systems, re-engineered flash physics by replacing silicon channels with two dimensional Dirac graphene and exploiting its ballistic charge transport. Combining ultralow energy with picosecond write speeds could eliminate separate highspeed SRAM caches and remove the longstanding memory bottleneck in AI inference and training hardware, where data shuttling, not arithmetic, now dominates power budgets. The team [which is now scaling the cell architecture and pursuing arraylevel demonstrations] did not disclose endurance figures or fabrication yield, but the graphene channel suggests compatibility with existing 2Dmaterial processes that global fabs are already exploring. The result is published in the journal Nature.

An anonymous reader quotes a report from Popular Mechanics: American composer Alvin Lucier was well-known for his experimental works that tested the boundaries of music and art. A longtime professor at Wesleyan University (before retiring in 2011), Alvin passed away in 2021 at the age of 90. However, that wasn't the end of his lifelong musical odyssey. Earlier this month, at the Art Gallery of Western Australia, a new art installation titled Revivification used Lucier's "brain matter" -- hooked up to an electrode mesh connected to twenty large brass plates -- to create electrical signals that triggered a mallet to strike the varying plates, creating a kind of post-mortem musical piece. Conceptualized in collaboration with Lucier himself before his death, the artists solicited the help of researchers from Harvard Medical School, who grew a mini-brain from Lucier's white blood cells. The team created stem cells from these white blood cells, and due to their pluripotency, the cells developed into cerebral organoids somewhat similar to developing human brains. "At a time when generative AI is calling into question human agency, this project explores the challenges of locating creativity and artistic originality," the team behind Revivification told The Art Newspaper. "Revivification is an attempt to shine light on the sometimes dark possibilities of extending a person's presence beyond the seemed finality of death." "The central question we want people to ask is: could there be a filament of memory that persists through this biological transformation? Can Lucier's creative essence persist beyond his death?" the team said.

OpenAI's latest reasoning models, o3 and o4-mini, hallucinate more frequently than the company's previous AI systems, according to both internal testing and third-party research. On OpenAI's PersonQA benchmark, o3 hallucinated 33% of the time -- double the rate of older models o1 (16%) and o3-mini (14.8%). The o4-mini performed even worse, hallucinating 48% of the time. Nonprofit AI lab Transluce discovered o3 fabricating processes it claimed to use, including running code on a 2021 MacBook Pro "outside of ChatGPT." Stanford adjunct professor Kian Katanforoosh noted his team found o3 frequently generates broken website links. OpenAI says in its technical report that "more research is needed" to understand why hallucinations worsen as reasoning models scale up.

With macOS now 24 years old and Apple officially designating all Intel-based Mac minis as "vintage" or "obsolete," The Register takes a look at new internet tools that help keep vintage Macs online and surprisingly relevant: Cameron Kaiser of Floodgap Systems is a valuable ally. His retro computing interests are broad, and we've mentioned him a few times on The Register, such as his deep dive into the revolutionary Canon Cat computer, and his evaluation of RISC-V hardware performance. Back in 2020, he revived the native Classic Mac OS port of the Lynx web browser, MacLynx. Earlier this month, he came back to it and has updated it again, including adding native Mac OS dialog boxes. His account is -- as usual -- long and detailed but it's an interesting read. He also maintains some other web browsers for elderly Macs, including TenFourFox for Mac OS X 10.4 and Classilla for Mac OS 8.6 and 9.x. If you're not up to git pull commands and elderly Mac OS X build tools, then there is a fork of TenFourFox that may be worth a look, InterWebPPC. It's not current with the new batch of patches, but we can still hope for another build. In other "Classic on the internet" news, although it's not a huge amount of use on its own, there's also a newly released Classic Mac OS version of Mbed-TLS on GitHub. This ports the SSL library -- also used in the super-lightweight Dillo browser -- to the older C89/C90 standard, so that it can build in CodeWarrior and run with OpenTransport from Mac OS 9 right back to later versions of Mac OS 7. Modern macOS is UNIX certified and as such it's not all that dissimilar from other Unix-like OSes, such as Linux and the BSD family. Classic Mac OS is a profoundly different beast, which makes porting modern code to it a complex exercise -- but equally, it's a good learning exercise, and we're delighted to see 21st century programmers exploring this 1980s OS. That may be part of the motivation behind the newly announced and still incomplete SDL 2 "rough draft" that appeared a week ago. It builds on the existing SDL 1.2 port, but so far, it's less complete -- for instance, there's no sound support.

Bluesky is testing a new verification system featuring blue checks issued by "Trusted Verifiers" like news organizations, rather than a centralized authority or pay-to-play model like X (formerly Twitter). "Looking at the comments on the pull request, it's clear this idea has sparked a lot of discussion and a lot of concern among the community who follow the platform's development closely," reports Neowin. "Many users voiced strong opposition to the change, arguing that the existing domain name verification is sufficient and more aligned with the decentralized ethos that Bluesky aims for." From the report: There's a general worry that adding a visual badge, especially one controlled in part by Bluesky, feels too much like the centralized systems they were trying to escape from by joining Bluesky: "Do not want. BSky is not Twitter 2.0. Do not become like Elon Musk. We came here to get AWAY from that bs." Several commenters also expressed that the current domain name system, while not perfect, is an elegant and decentralized way to build trust, and that adding this new layer feels redundant and gives too much power to centralized entities, including Bluesky itself: "Let's please not do this. Domain names as user IDs is an elegant solution as a system of trust that builds off the infrastructure of an open web." While the majority of the initial reaction seems negative, focusing on concerns about centralization and the value of the existing domain verification, there was some support for the idea of a visual badge, making it easier to quickly identify genuine accounts. One user commented: "I support this change. I like someone to verify that the account is indeed genuine and the username field showing the domain isn't helpful that much... A badge makes it easier to just tick it off that it's genuine." The PR author, estrattonbailey, later added a description to the pull request explaining that the goal is a "stronger visual signal" for notable accounts and clarifying it's not a paid service.

Netflix's Q1 revenue rose to $10.5 billion, a 13% increase from last year, while net income grew to $2.9 billion. The company says it expects more growth in the coming months when it sees "the full quarter benefit from recent price changes and continued growth in membership and advertising revenue." The Verge reports: Netflix raised the prices across most of its plans in January, with its premium plan hitting $24.99 per month. It also increased the price of its Extra Member option -- its solution to password sharing -- to $8.99 per month. Though Netflix already rolled out the increase in the US, UK, and Argentina, the streamer now plans to do the same in France. This is the first quarter that Netflix didn't reveal how many subscribers it gained or lost. It decided to only report "major subscriber milestones" last year, as other streams of revenue continue to grow, like advertising, continue to grow. Netflix last reported having 300 million global subscribers in January. During an earnings call on Thursday, Netflix co-CEO Greg Peters said the company expects to "roughly double" advertising revenue in 2025. The company launched its own advertising technology platform earlier this month. There are some changes coming to Netflix, too, as Peters confirmed that its homepage redesign for its TV app will roll out "later this year." He also hinted at adding an "interactive" search feature using "generative technologies," which sounds a lot like the AI feature Bloomberg reported on last week.

An anonymous reader quotes a report from SecurityWeek: An October 2024 study by Software AG suggests that half of all employees are Shadow AI users, and most of them wouldn't stop even if it was banned. The problem is the ease of access to AI tools, and a work environment that increasingly advocates the use of AI to improve corporate efficiency. It is little wonder that employees seek their own AI tools to improve their personal efficiency and maximize the potential for promotion. It is frictionless, says Michael Marriott, VP of marketing at Harmonic Security. 'Using AI at work feels like second nature for many knowledge workers now. Whether it's summarizing meeting notes, drafting customer emails, exploring code, or creating content, employees are moving fast.' If the official tools aren't easy to access or if they feel too locked down, they'll use whatever's available which is often via an open tab on their browser. There is almost also never any malicious intent (absent, perhaps, the mistaken employment of rogue North Korean IT workers); merely a desire to do and be better. If this involves using unsanctioned AI tools, employees will likely not disclose their actions. The reasons may be complex but combine elements of a reluctance to admit that their efficiency is AI assisted rather than natural, and knowledge that use of personal shadow AI might be discouraged. The result is that enterprises often have little knowledge of the extent of Shadow IT, nor the risks it may present. According to an analysis from Harmonic, ChatGPT is the dominant gen-AI model used by employees, with 45% of data prompts originating from personal accounts (such as Gmail). Image files accounted for 68.3%. The report also notes that 7% of empmloyees were using Chinese AI models like DeepSeek, Baidu Chat and Qwen. "Overall, there has been a slight reduction in sensitive prompt frequency from Q4 2024 (down from 8.5% to 6.7% in Q1 2025)," reports SecurityWeek. "However, there has been a shift in the risk categories that are potentially exposed. Customer data (down from 45.8% to 27.8%), employee data (from 26.8% to 14.3%) and security (6.9% to 2.1%) have all reduced. Conversely, legal and financial data (up from 14.9% to 30.8%) and sensitive code (5.6% to 10.1%) have both increased. PII is a new category introduced in Q1 2025 and was tracked at 14.9%."

Some actors who sold their likenesses to AI video companies like Synthesia now regret the decision, after finding their digital avatars used in misleading, embarrassing, or politically charged content. Ars Technica reports: Among them is a 29-year-old New York-based actor, Adam Coy, who licensed rights to his face and voice to a company called MCM for one year for $1,000 without thinking, "am I crossing a line by doing this?" His partner's mother later found videos where he appeared as a doomsayer predicting disasters, he told the AFP. South Korean actor Simon Lee's AI likeness was similarly used to spook naive Internet users but in a potentially more harmful way. He told the AFP that he was "stunned" to find his AI avatar promoting "questionable health cures on TikTok and Instagram," feeling ashamed to have his face linked to obvious scams. [...] Even a company publicly committed to ethically developing AI avatars and preventing their use in harmful content like Synthesia can't guarantee that its content moderation will catch everything. A British actor, Connor Yeates, told the AFP that his video was "used to promote Ibrahim Traore, the president of Burkina Faso who took power in a coup in 2022" in violation of Synthesia's terms. [...] Yeates was paid about $5,000 for a three-year contract with Synthesia that he signed simply because he doesn't "have rich parents and needed the money." But he likely couldn't have foreseen his face being used for propaganda, as even Synthesia didn't anticipate that outcome. Others may not like their AI avatar videos but consider the financial reward high enough to make up for the sting. Coy confirmed that money motivated his decision, and while he found it "surreal" to be depicted as a con artist selling a dystopian future, that didn't stop him from concluding that "it's decent money for little work." Potentially improving the climate for actors, Synthesia is forming a talent program that it claims will give actors a voice in decision-making about AI avatars. "By involving actors in decision-making processes, we aim to create a culture of mutual respect and continuous improvement," Synthesia's blog said.

IBM is mandating that U.S. sales and Cloud employees return to the office at least three days a week, with work required at designated client sites, flagship offices, or sales hubs. According to The Register, some IBM employees argue that these policies "represent stealth layoffs because older (and presumably more highly compensated) employees tend to be less willing to uproot their lives, and families where applicable, than the 'early professional hires' IBM has been courting at some legal risk." From the report: In a staff memo seen by The Register, Adam Lawrence, general manager for IBM Americas, billed the return-to-office for most stateside sales personnel as a "return to client initiative."Citing how "remarkable it is when our teams work side by side" at IBM's swanky Manhattan flagship office, unveiled in September 2024, Lawrence added IBM is investing in an Austin, Texas, office to be occupied in 2026. Whether US sales staff end up working in NYC, Austin, or some other authorized location, Lawrence told them to brace for -- deep breath -- IBM's "new model" of "effective talent acquisition, deployment, and career progression." We're told that model is "centered on client proximity for those dedicated to specific clients, and anchored on core IBM locations for those dedicated to territories or those in above-market leadership roles." The program requires most IBM US sales staff "to work at least three days a week from the client location where their assigned territory decision-makers work, a flagship office, or a sales hub." Those residing more than 50 miles from their assigned location will be offered relocation benefits to move. Sales hubs are an option only for those with more than one dedicated account. [...] IBM's office policy change reached US Cloud employees in an April 10 memo from Alan Peacock, general manager of IBM Cloud. Peacock set a July 1, 2025, deadline for US Cloud employees to work from an office at least three days per week, with relocating workers given until October 1, 2025. The employee shuffling has been accompanied by rolling layoffs in the US, but hiring in India -- there are at least 10x as many open IBM jobs in India as there are in any other IBM location, according to the corporation's career listings. And earlier this week, IBM said it "is setting up a new software lab in Lucknow," India.
