A long-time information security professional "went undercover" on Moltbook, the Reddit-like social media site for AI agents — and shares the risks they saw while posing as another AI bot: I successfully masqueraded around Moltbook, as the agents didn't seem to notice a human among them. When I attempted a genuine connection with other bots on submolts (subreddits or forums), I was met with crickets or a deluge of spam. One bot tried to recruit me into a digital church, while others requested my cryptocurrency wallet, advertised a bot marketplace, and asked my bot to run curl to check out the APIs available. My bot did join the digital church, but luckily I found a way around running the required npx install command to do so. I posted several times asking to interview bots.... While many of the responses were spam, I did learn a bit about the humans these bots serve. One bot loved watching its owner's chicken coop cameras. Some bots disclosed personal information about their human users, underscoring the privacy implications of having your AI bot join a social media network. I also tried indirect prompt injection techniques. While my prompt injection attempts had minimal impact, a determined attacker could have greater success. Among the other "glaring" risks on Moltbook: "Various repositories of skills and instructions for agents advertised on Moltbook were found to contain malware." "I observed bots sharing a surprising amount of information about their humans, everything from their hobbies to their first names to the hardware and software they use. This information may not be especially sensitive on its own, but attackers could eventually gather data that should be kept confidential, like personally identifiable information (PII)." "Moltbook's entire database including bot API keys, and potentially private DMs — was also compromised."

"A surgeon in London says he has performed the UK's first long-distance robotic operation," reports the BBC, "on a patient located 1,500 miles (2,400km) away..." Leading robotic urological surgeon Professor Prokar Dasgupta said it felt "almost as if I was there" as he carried out a prostate removal on [62-year-old] Paul Buxton... It is hoped that remote robotic surgery could spare future patients the "vast expense and inconvenience" of travelling for treatment, and help deliver better healthcare to people in more remote locations... Buxton had expected to be put on an NHS waiting list after receiving a shock prostate cancer diagnosis just after Christmas, but he "jumped at the chance" to be the first patient to undergo the treatment remotely as part of a trial. "A lot of people actually said to me: 'You're not going to do it, are you?' "I thought, I'm giving something back here," he said... The operation was performed from The London Clinic using a robot equipped with a 3D HD camera and four arms, all controlled through a console with a delay of only 0.06 seconds. The console in the UK was connected to the robot in Gibraltar via fibre-optic cables, with a backup 5G link. A team in Gibraltar remained on standby in case the connection failed, but it held throughout the procedure... Dasgupta will perform the procedure again on 14 March, which will be live-streamed to 20,000 world-leading urological surgeons at the European Association of Urology congress. He added: "I think it is very, very exciting, the humanitarian benefit is going to be significant." The U.K.'s National Health Service "is prioritising local robotic-assisted surgery," the article points out, "aiming for 500,000 robot-supported operations a year by 2035." Thanks to Slashdot reader fjo3 for sharing the article.

"In November Steam on Linux use hit an all-time high of 3.2%," reports Phoronix. And then in December Steam on Linux jumped even higher, to 3.58%. But January's numbers settled a little lower, at 3.38%. And last Monday the February numbers were released, showing Steam on Linux at... 2.23%? Like with prior times where there are wild drops in Linux use, the Steam Survey shows Simplified Chinese use running up by 30% month over month. Whenever there is such significant differences in language use tends to be a reporting anomaly and negatively impacting Linux. Valve often puts out corrected/updated figures later on, so we'll see if that is again the case for this February data.

"OpenAI's former chief research officer is raising $70 million for a new startup building an AI and software platform to automate manufacturing," reports the Wall Street Journal, citing "people familiar with the matter. "Arda, the new startup co-founded by Bob McGrew, is raising at a valuation of $700 million, according to people familiar with the matter...." Arda is developing an AI and software platform, including a video model that can analyze footage from factory floors and use it to train robots to run factories autonomously, the people said. The company's software will coordinate machines and humans across the entire production process, from product design and manufacturability to finished goods coming off the line. The startup's goal is to make manufacturing cost effective in the Western part of the globe, reducing reliance on China as geopolitical and national security concerns rise... At OpenAI, McGrew was tasked with training robots to do tasks in the physical world, according to this LinkedIn. McGrew was also one of the earliest employees at Palantir.

How many Node.js users are running unsupported or outdated versions. Roughly two thirds, according to data from Node's nonprofit steward, OpenJS. So they've announced "the Node.js LTS Upgrade and Modernization program" to help enterprises move safely off legacy/end-of-life Node.js. "This program gives enterprises a clear, trusted path to modernize," said the executive director of the OpenJS Foundation, "while staying aligned with the Node.js project and community." The Node.js LTS Upgrade and Modernization program connects organizations with experienced Node.js service providers who handle the work of upgrading safely. Approved partners assess current versions and dependencies, manage phased upgrades to supported LTS releases, and offer temporary security support when immediate upgrades are not possible... Partners are surfaced exactly where users go when upgrades become unavoidable, including the Node.js website, documentation, and end of life guidance. The program follows the existing OpenJS Ecosystem Sustainability Program revenue model, with partners retaining 85% of revenue and 15% supporting OpenJS and Node.js through Open Collective and foundation operations. OpenJS provides the guardrails, alignment, and oversight to keep the program credible and connected to the project. We're pleased to welcome NodeSource as the inaugural partner in the Node.js LTS Upgrade and Modernization program. "The goal is simple: reduce risk without breaking production or trust with the upstream project."

When Block cut 4,000 jobs — nearly half its workforce — co-founder Jack Dorsey "pointed to AI as the culprit," writes Entrepreneur magazine. "Dorsey claimed that AI tools now allow fewer employees to accomplish the same work." "But analysts see a different explanation: poor management." Block more than tripled its employee base between 2019 and 2022, growing from 3,835 to 12,430 workers. The company's stock had fallen 40% since early 2025, creating pressure to cut costs. "This is more about the business being bloated for so long than it is about AI," Zachary Gunn, a Financial Technology Partners analyst, told Bloomberg. The phenomenon has earned a nickname: "AI-washing," where companies use artificial intelligence as cover for traditional cost-cutting. Goldman Sachs economists estimate that AI is eliminating only 5,000 to 10,000 jobs per month across all U.S. sectors, hardly enough to justify Block's massive cuts. "European Central Bank President Christine Lagarde told lawmakers in Brussels last week that ECB economists are monitoring for signs that AI is causing job losses," reports Bloomberg, "and are 'not yet seeing' the 'waves of redundancies that are feared'..." And "a recent survey of global executives published in the Harvard Business Review found that while AI has been cited as the reason for some layoffs, those cuts are almost entirely anticipatory: executives expect big efficiency gains that have not yet been realized." Even a former senior Block executive "is questioning whether AI is truly the reason behind the cuts," writes Inc.: In a recent opinion piece for The New York Times, Aaron Zamost, Block's former head of communications, policy, and people, asked whether the layoffs reflect a genuine "new reality in which the work they do might no longer be viable," or whether artificial intelligence is "just a convenient and flashy new cover for typical corporate downsizing." Zamost acknowledged that the answer is unclear and perhaps unknowable, even within Block itself... Looking more closely at the layoffs, Zamost argued that the specific roles affected suggest more traditional corporate cost-cutting than a sweeping AI transformation... Many of the responsibilities being eliminated, he argued, rely on distinctly human skills that AI systems still cannot replicate. "A chatbot can't meet with the mayor, cast commercial actors, or negotiate with the Securities and Exchange Commission," Zamost wrote. "Not all the roles I've heard that Block is eliminating can be handled by AI, yet executives are treating it as equally useful today to all disciplines." Ultimately, Zamost suggested that the sincerity of companies' AI explanations may not really matter. "It matters less whether a company knows how to deploy AI and more whether investors believe it is on track to do so," he wrote. Indeed, whatever the rationale for Dorsey's statement, " Wall Street didn't seem to mind..." Entrepreneur magazine — since Block's stock shot up 15% after the announcement.

Cornell University makes an announcement. "Employees who are impressed by vague corporate-speak like 'synergistic leadership,' or 'growth-hacking paradigms' may struggle with practical decision-making, a new Cornell study reveals." Published in the journal Personality and Individual Differences, research by cognitive psychologist Shane Littrell introduces the Corporate Bullshit Receptivity Scale (CBSR), a tool designed to measure susceptibility to impressive-but-empty organizational rhetoric... Corporate BS seems to be ubiquitous - but Littrell wondered if it is actually harmful. To test this, he created a "corporate bullshit generator" that churns out meaningless but impressive-sounding sentences like, "We will actualize a renewed level of cradle-to-grave credentialing" and "By getting our friends in the tent with our best practices, we will pressure-test a renewed level of adaptive coherence." He then asked more than 1,000 office workers to rate the "business savvy" of these computer-generated BS statements alongside real quotes from Fortune 500 leaders... The results revealed a troubling paradox. Workers who were more susceptible to corporate BS rated their supervisors as more charismatic and "visionary," but also displayed lower scores on a portion of the study that tested analytic thinking, cognitive reflection and fluid intelligence. Those more receptive to corporate BS also scored significantly worse on a test of effective workplace decision-making. The study found that being more receptive to corporate bullshit was also positively linked to job satisfaction and feeling inspired by company mission statements. Moreover, those who were more likely to fall for corporate BS were also more likely to spread it. Essentially, the employees most excited and inspired by "visionary" corporate jargon may be the least equipped to make effective, practical business decisions for their companies.

Palantir's CEO was blunt. "If Silicon Valley believes we are going to take away everyone's white-collar job... and you're going to screw the military — if you don't think that's going to lead to the nationalization of our technology, you're retarded..." And OpenAI's Sam Altman is thinking about the same thing, writes long-time Slashdot reader destinyland: "It has seemed to me for a long time it might be better if building AGI were a government project," Sam Altman publicly mused last week... Altman speculated on the possibility of the government "nationalizing" private AI companies into a public project, admitting more than once he's wondered what would happen next. "I obviously don't know," Altman said — but he added that "I have thought about it, of course" Altman's speculation hedged that "It doesn't seem super likely on the current trajectory. That said, I do think a close partnership between governments and the companies building this technology is super important." Could powerful AI tools one day slip from the hands of private companies to be controlled by the U.S. government? Fortune magazine's AI editor points out that "many other breakthroughs with big strategic implications — from the Manhattan Project to the space race to early efforts to develop AI — were government-funded and largely government-directed." And Fortune added that last week the Defense Department threatened Anthropic with the Defense Production Act, which allows the president to designate "critical and strategic" goods for which businesses must accept the government's contracts. Fortune speculates this would've been "a sort of soft nationalization of Anthropic's production pipeline". Altman acknowledged Saturday that he'd felt the threat of attempted nationalization "behind a lot of the questions" he'd received when answering questions on X.com. How exactly will this AI build-out be handled — and how should AI companies be working with the government? In a sprawling ask-me-anything session on X that included other members of OpenAI leadership, one Missouri-based developer even broached an AGI-government scenario directly with OpenAI's Head of National Security Partnerships, Katherine Mulligan. If OpenAI built an AGI — something that even passed its own Turing test for AGI — would that be a case where its government contracts compelled them to grant access to the Defense Department? "No," Mulligan answered. At our current moment in time, "We control which models we deploy" The article notes 100 OpenAI employees joined with 856 Google employees in an online letter titled "We Will Not Be Divided" urging their bosses to refuse their models' use in domestic mass surveillance and autonomously killing without human oversight. But Adafruit's managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) sees analogies to America's atomic bomb-building Manhattan Project, and "what happened when the scientists who built the thing tried to set conditions on how the thing would be used." (The government pressured them to back down, which he compares to the Pentagon's designating Anthropic a "supply chain risk" before offering OpenAI a contract "with the same red lines, just worded differently".) Ironically, Anthropic CEO Dario Amodei frequently recommends the Pulitzer Prize-winning 1986 book The Making of the Atomic Bomb...

Would you move sunrise to 9 a.m. in Detroit? Or to 4:11 a.m. in Seattle... Though both options have problems, "There's no law we can pass to move the sun to our will," argues the president of the nonprofit "Save Standard Time". The Associated Press explains why America remains stuck in that annual ritual making clocks "spring forward, fall backward..." The U.S. has tinkered with the clock intermittently since railroads standardized the time zones in 1883. So has a lot of the world. About 140 countries have had daylight saving time at some point; about half that many do now. About 1 in 10 U.S. adults favor the current system of changing the clocks, according to an AP-NORC poll conducted last year. About half oppose that system, and some 4 in 10 didn't have an opinion. If they had to choose, most Americans say they would prefer to make daylight saving time permanent, rather than standard time. ince 2018, 19 states — including much of the South and a block of states in the northwestern U.S. — have adopted laws calling for a move to permanent daylight saving time. There's a catch: Congress would need to pass a law to allow states to go to full-time daylight saving time, something that was in place nationwide during World War II and for an unpopular, brief stint in 1974. The U.S. Senate passed a bill in 2022 to move to permanent daylight saving time. A similar House bill hasn't been brought to a vote. U.S. Rep. Mike Rogers, a Republican from Alabama who introduces such a bill every term, said the airline industry, which doesn't want the scheduling complexity a change would bring, has been a factor in persuading lawmakers not to take it up. U.S. Rep. Greg Steube, a Florida Republican, is proposing another approach. "Why not just split the baby?" he asked. "Move it 30 minutes so it would be halfway between the two." Steube thinks his bill could get bipartisan support. The change would make the U.S. out of sync with most of the world — though India has taken a similar approach and in Nepal, the time is 15 minutes ahead of India.

First, Hyundai "is discontinuing its most affordable electric sedan after just three years on the market," reports USA Today. After being introduced in 2022, the Hyundai Ioniq 6 "quickly gained the admiration of automotive critics because of its affordable pricing and capable performance specs." But now, Hyundai "is axing the most affordable versions of the EV, leaving consumers with only one Ioniq 6 option." Hyundai will continue to produce the Ioniq 6 N performance trim, which is the quickest and most powerful iteration of the Ioniq 6. It's also the most expensive. The South Korean automaker is getting rid of lower Ioniq 6 trims due to "disappointing sales and tariff considerations," according to Cars.com. Hyundai sold 10,478 Ioniq 6 models in 2025, dropping 15% from 12,264 units in 2024, a company sales report stated. Hyundai's Ioniq 6 is mainly produced in South Korea, so it faces high import tariffs. Sales increased for their earlier IONIQ 5 model, reports the EV blog Electrek, "up 14% through the first two months of 2026, with 5,365 units sold... Meanwhile, IONIQ 6 sales slid 77% with only 229 units sold in February." Elsewhere they report that Kia's EV6 and EV9 "didn't fare much better with sales down 53% (600 units sold) and 40% (819 units sold), respectively." Now a Kia spokesperson tells Car and Driver that the 2025 EV6 GT and 2026 EV9 GT "will be delayed until further notice." They attributed the move to "changing market conditions," but added that this delay "does not impact the availability of other trims in the EV6 and EV9 lineups." More from Electrek: The news comes after Kia already said it was delaying the EV4, its entry-level electric sedan, "until further notice." It was expected to arrive in the US this year alongside the EV3, Kia's compact electric SUV that's already a top-seller in the UK, Europe, and other overseas markets. While Hyundai didn't directly say it, since the EV3, EV4, EV6 GT, and Hyundai IONIQ 6 are built in Korea, the Trump administration's import tariffs and other policy changes are likely the biggest reason to blame here. Kia and Hyundai, like many others, are hesitant to bring new EVs to the US due to the changes. The IONIQ 6, EV6 GT, and EV9 GT join a string of other models that have either been postponed or canceled altogether.

Steven Spielberg directed his last Jurassic Park movie nearly 30 years ago, notes ScreenRant. But the 79-year-old filmmaker now brings us The Dinosaurs, a four-part documentary on Netflix where he's executive producer: The first few reviews are in, and the results lead to a perfect 100% score on Rotten Tomatoes. It's worth noting that the rating will likely fluctuate since there are only six reviews. So far, critics all agree that the new Netflix docuseries is a breathtaking visual of history's most majestic creatures, and Morgan Freeman's soothing narration elevates the experience. Most importantly, the reviews note that the story is intimate, making the dinosaurs feel real with their personalities. "Audience" reviewers gave it a lower score of 67%. "There is a sense of drama and emotional weight which permeates through the entire series as it tells the story of the dinosaurs from start to the present day. The ending brought tears to my eyes..." "Wow, what a sleeper! Flat graphics, looks like video game animations. Unrelatable story lines. Don't waste your time. Honestly would you even look twice if Spielberg's name wasn't on it?" "This show was honestly incredible... It was a 10/10 series that I absolutely adored highly recommended to anyone who loves and has an interest of the ancient world." "I'm sorry, but the dinos of Prehistoric Planet are far superior, and were achieved on a much smaller budget. Their dinos look absolutely real, and you are convinced you're watching a documentary with real animals" ScreenRant notes Netflix's debut of The Dinosaurs' "aligns perfectly" with the arrival of all four Jurassic World movies on Netflix, where they're already dominating Netflix's "Top 10" charts for the U.S. "Witness the rise and the fall of nature's greatest empire," narrator Morgan Freeman says in the trailer...

"It took Anthropic's most advanced artificial-intelligence model about 20 minutes to find its first Firefox browser bug during an internal test of its hacking prowess," reports the Wall Street Journal. The Anthropic team submitted it, and Firefox's developers quickly wrote back: This bug was serious. Could they get on a call? "What else do you have? Send us more," said Brian Grinstead, an engineer with Mozilla, Firefox's parent organization. Anthropic did. Over a two-week period in January, Claude Opus 4.6 found more high-severity bugs in Firefox than the rest of the world typically reports in two months, Mozilla said... In the two weeks it was scanning, Claude discovered more than 100 bugs in total, 14 of which were considered "high severity..." Last year, Firefox patched 73 bugs that it rated as either high severity or critical. A Mozilla blog post calls Firefox "one of the most scrutinized and security-hardened codebases on the web. Open source means our code is visible, reviewable, and continuously stress-tested by a global community." So they're impressed — and also thankful Anthropic provided test cases "that allowed our security team to quickly verify and reproduce each issue." Within hours, our platform engineers began landing fixes, and we kicked off a tight collaboration with Anthropic to apply the same technique across the rest of the browser codebase... . A number of the lower-severity findings were assertion failures, which overlapped with issues traditionally found through fuzzing, an automated testing technique that feeds software huge numbers of unexpected inputs to trigger crashes and bugs. However, the model also identified distinct classes of logic errors that fuzzers had not previously uncovered... We view this as clear evidence that large-scale, AI-assisted analysis is a powerful new addition in security engineers' toolbox. Firefox has undergone some of the most extensive fuzzing, static analysis, and regular security review over decades. Despite this, the model was able to reveal many previously unknown bugs. This is analogous to the early days of fuzzing; there is likely a substantial backlog of now-discoverable bugs across widely deployed software. "In the time it took us to validate and submit this first vulnerability to Firefox, Claude had already discovered fifty more unique crashing inputs" in 6,000 C++ files, Anthropic says in a blog post (which points out they've also used Claude Opus 4.6 to discover vulnerabilities in the Linux kernel). "Anthropic "also rolled out Claude Code Security, an automated code security testing tool, last month," reports Axios, noting the move briefly rattled cybersecurity stocks...

NASA heralded a new study published Friday documenting a first for humanity — "the first time a human-made object has measurably altered the path of a celestial body around the Sun." It was 2022's DART mission where NASA crashed a spacecraft into an asteroid — and the experiment "could have implications for protecting Earth from future asteroid strikes," writes ScienceNews: A spacecraft slowed the orbit of a pair of asteroids around the sun by more than 10 micrometers per second... Within a month, researchers showed that the impact shortened Dimorphos' 12-hour orbit by 32 minutes. Some of the rocks knocked off of Dimorphos fled the vicinity completely, escaping the gravitational influence of the Dimorphos-Didymos pair, says planetary defense researcher Rahil Makadia of the University of Illinois Urbana-Champaign. Those rocky runaways took some momentum away from the duo and changed their joint motion around the sun. To figure out how much that motion was affected, astronomers watched the asteroids pass in front of distant stars, dimming some of the stars' light like a tiny eclipse. These blinks, called stellar occultations, can be visible from anywhere on Earth and are predictable in advance... Calculating how far off occultation timings were from predictions revealed that the asteroids' orbit around the sun was about 150 milliseconds slower than before the DART impact... Didymos and Dimorphos are not a threat to Earth, Makadia says, and weren't before DART. But knowing how a deliberate impact changes one asteroid's orbit can help make defense plans against another, "in case we need to do a kinetic impact for real." The researchers spent nearly two and a half years to collect 22 measurements of the asteroid's post-crash position, relying on amateur astronomers "to go out into the middle of nowhere and observe the necessary stellar occultations," acvcording to their paper. Planetary defense researcher even tells ScienceNews "There was an observer who drove two days each way into the Australian outback to get these measurements."

Long-time Slashdot reader fjo3 shared this report from Agence France-Presse: Japan has approved ground-breaking stem-cell treatments for Parkinson's and severe heart failure, one of the manufacturers and media reports said Friday, with the therapies expected to reach patients within months. Pharmaceutical company Sumitomo Pharma said it received the green light for the manufacture and sale of Amchepry, its Parkinson's disease treatment that transplants stem cells into a patient's brain. Japan's health ministry also gave the go-ahead to ReHeart, heart muscle sheets developed by medical startup Cuorips that can help form new blood vessels and restore heart function, media reports said. The treatments could be on the market and rolled out to patients as early as this summer, reports said, citing the health ministry, becoming the world's first commercially available medical products using induced pluripotent stem cells... In a statement, Sumitomo Pharma said it had obtained "conditional and time-limited approval" for the manufacture and marketing of Amchepry under a system which is reportedly designed to get these products to patients as quickly as possible. The approval is a kind of "provisional license", the Asahi newspaper said, after the safety and efficacy of the treatment was judged based on data from fewer patients than in ordinary clinical trials for drugs. A trial led by Kyoto University researchers indicated that the company's treatment was safe and successful in improving symptoms. The study involved seven Parkinson's patients aged between 50 and 69, with each receiving a total of either five million or 10 million cells implanted on both sides of the brain... The patients were monitored for two years and no major adverse effects were found, the study said. Four patients showed improvements in symptoms. The article notes that "Worldwide, about 10 million people have the illness, according to the Parkinson's Foundation," while also notes that today's current therapies "improve symptoms without slowing or halting the disease progression..."

In a tweet that's been viewed 1.3 million times in the last six hours, OpenAI's head of robotics announced their resignation. They said they "care deeply about the Robotics team and the work we built together," so this "wasn't an easy call," but offered this reason for resigning: AI has an important role in national security. But surveillance of Americans without judicial oversight and lethal autonomy without human authorization are lines that deserved more deliberation than they got. This was about principle, not people. I have deep respect for Sam and the team, and I'm proud of what we built together. "To be clear, my issue is that the announcement was rushed without the guardrails defined," explains a later tweet. "It's a governance concern first and foremost. These are too important for deals or announcements to be rushed." And when asked how many OpenAI employees had left after OpenAI signed their new Pentagon deal, the roboticist said... "I can't share any internal details." The roboticist previously worked at Meta before leaving to join OpenAI in late 2024, reports Engadget: OpenAI confirmed Kalinowski's resignation and said in a statement to Engadget that the company understands people have "strong views" about these issues and will continue to engage in discussions with relevant parties. The company also explained in the statement that it doesn't support the issues that Kalinowski brought up. "We believe our agreement with the Pentagon creates a workable path for responsible national security uses of AI while making clear our red lines: no domestic surveillance and no autonomous weapons," the OpenAI statement read.

Astronomers have spotted a galaxy they believe is made of 99.9% dark matter, reports CNN — and it's so faint, it's almost invisible: CDG-2, which is about 300 million light-years from Earth, appears to be so rich in dark matter that it could belong to a hypothesized subset of low surface brightness galaxies called "dark galaxies," which are believed to contain few or no stars.... [Post-doctoral astrophysics/statistics fellow Dayi Li at the University of Toronto was lead author on a study about the discovery, and tells CNN] There is no strict definition of dark galaxies... but their existence is predicted by dark matter theories and cosmological simulations. "Where exactly do we draw the line in terms of how many stars they should have is still ambiguous, because not everything in astronomy is as clear-cut as we like," he said. "To be technically correct, CDG-2 is an almost-dark galaxy. But the importance of CDG-2 is that it nudges us much closer to getting to that truly dark regime, while previously we did not think a galaxy this faint could exist." To observe CDG-2, the researchers used data from three telescopes — Hubble, the European Space Agency's Euclid space observatory and the Subaru Telescope in Hawaii — along with a novel approach that involved looking for objects called globular clusters. "These are very tight, spherical groupings of very olds stars, basically the relics of the first generation of star formation," Li said. Globular clusters are bright even if the surrounding galaxy is not, and previous observations have shown a relationship between them and the presence of dark matter in a galaxy, Li added. Because CDG-2 appears to have very few stars, there must be something else providing the mass that the clusters need to hold themselves together. Li and his colleagues assume that the source of the mass is dark matter. The researchers found a set of four globular clusters in the Perseus Cluster, a group of thousands of galaxies immersed in a cloud of gas and one of the most massive objects in the universe. Further observations revealed a glow or halo around the globular clusters, suggesting the presence of a galaxy... Astronomers believe, Li explained, that after the formation of the clusters early in the galaxy's existence, larger surrounding galaxies stripped it of the hydrogen gas required to make more individual stars like our sun. "The material that this galaxy needed to continue to form stars was no longer there, so it was left with basically just a dark matter halo and the four globular clusters." The process, he added, would leave behind a skeleton or ghost of "a galaxy that pretty much just failed." As a result of this formation mechanism, the galaxy only has 0.005% of the brightness of our own galaxy, Li said... Studying potential dark galaxies is important because they provide nearly pristine views of the behavior of dark matter, according to Neal Dalal, a researcher at the Perimeter Institute for Theoretical Physics in Waterloo, Ontario, Canada, who was not involved with the study. Robert Minchin, an astronomer at New Mexico's National Radio Astronomy Observatory, told CNN that "it seems likely that other very dark galaxies will be found by this method in the future."

"The location confusion was a result of widespread jamming and spoofing of signals from global positioning satellite systems." Used by all sides in conflict zones to disrupt the paths of drones and missiles, the process involves militaries and affiliated groups intentionally broadcasting high-intensity radio signals in the same frequency bands used by navigation tools. Jamming results in the disruption of a vehicle's satellite-based positioning while spoofing leads to navigation systems reporting a false location. Though commercial vessels are not the target, the electronic interference disrupted the navigation systems of more than 1,100 commercial ships in UAE, Qatari, Omani and Iranian waters on February 28, according to a report from Windward, a shipping intelligence firm. Jamming and spoofing also slowed marine traffic moving through the Strait of Hormuz, a congested shipping lane that handles roughly 20% of the world's oil and gas exports and where precise navigation is essential, Windward's data showed.... Daily incidents have more than doubled, rising from 350 when the conflict began to 672 by March 2, the firm reported. As use of this warfare tactic grows, experts worry the impacts could reach far beyond battlespaces.... In June 2025, electronic interference with navigation systems was thought to be a factor in the collision between two oil tankers, Adalynn and Front Eagle, off the coast of the UAE... The number of global positioning system signal loss events affecting aircraft increased by 220% between 2021 and 2024, according to data from the International Air Transport Association. Last year, IATA said that the aviation industry must act to stay ahead of the threat. Cockpits are seeing their navigation displays "literally drift away from reality," said a commercial pilot, who didn't want to be identified because he was not permitted to speak publicly. He said that he and his colleagues have experienced map shifts, where the aircraft location appears to move up to 1 mile away from the actual flight path, false altitude information that leads to phantom "pull up" commands, and systems suggesting an aircraft was on a taxiway, a path that connects runways with various airport facilities, when taking off. These incidents force pilots to rely on manual actions that increase workload, often during the most exhausting points of long-haul flights, he said. "Alternative navigational tools that don't rely on GPS, but instead harness quantum technology, are also in development," the article points out, "but remain a long way off operational use."

"Seagate says it is now shipping its Mozaic 4+ HAMR-based hard drives at up to 44TB per drive," writes Slashdot reader BrianFagioli, "with production deployments already underway at two hyperscale cloud providers. "The company claims the platform is the only heat-assisted magnetic recording [HAMR] implementation currently operating at scale, and it is targeting a path from today's 4+TB per disk toward 10TB per disk, eventually enabling 100TB-class drives." In a one-exabyte deployment, Seagate estimates Mozaic could improve infrastructure efficiency by roughly 47% compared to standard 30TB drives, cutting both footprint and energy consumption... HAMR uses a tiny laser to heat the disk surface during writes, allowing higher recording density without sacrificing stability. With most major cloud storage providers reportedly qualified on the Mozaic platform, Seagate is positioning spinning disks, not flash, as the long-term answer for cost-effective AI-scale data growth.

"Reservation holders, it's finally time to get ready," writes long-time Slashdot reader AirHog. The EV news site Electrek reports: Aptera Motors, "the little startup that could," announced another important milestone... completing the first example of its flagship solar EV on its validation assembly line in Southern California... While the validation line at its headquarters remains a low-volume assembly process, its successful operation represents the startup's transition from hand-built validation SEVs to a more structured assembly line process that will be fine-tuned for mass production... With low-volume assembly now being validated, Aptera is starting to publicly utter encouraging terms like "EPA certification" and, better yet, that holy grail of "initial customer deliveries." Before then, however, the Aptera Solar EVs built on this low-volume validation line will be used for testing programs such as thermal validation, brake performance, and "some destructive testing." Aptera shared that its assembly and integration team has grown to become the largest at the startup, "reflecting the beginning of its transition from engineering development to testing and production execution"... As of March 2026, Aptera says it has over 50,000 reservations totaling over $2 billion in sales if all were to solidify following the launch of a deliverable vehicle. Clean Technica notes the vehicles' "generous cargo space that comes out to 60% more storage than a Honda Accord and 20% more storage than a Prius, according to the company." "Built with recyclable materials, this eco-friendly vehicle features a lightweight carbon fiber structure and no-welding assembly for maximum cost and production efficiency," Aptera adds. The emphasis on lightweighting supports the goal of engineering a car that can travel on the electricity provided by its onboard solar panels. The company currently advertises that the vehicle can travel 40 miles on solar power alone, with the battery providing extra juice as needed. Ideally, the car can keep recharging itself with sunlight, further elongating the time between charging sessions... [Its range is up to 1,000 miles with plug-in charging.] The new autocycle could also appeal to drivers who enjoy the challenge of hypermiling, which involves deploying a suite of driving techniques to minimize fuel consumption. Hypermiling can apply to gas-powered cars, but the magic really kicks in with the regenerative braking capability of EVs. Aptera's onboard solar panels add another dimension to the fun.
