2001: "Brookhaven Labs has produced for the first time collisions of gold nuclei at a center of mass energy of 200GeV/nucleon." 2002: "There may be a new type of matter according to researchers at Brookhaven National Laboratory." 2010: The hottest man-made temperatures ever achived were a record 4 trillion degree plasma experiment at Brookhaven National Laboratory in New York... anointed the Guinness record holder." 2023: "Scientists at Brookhaven National Laboratory have uncovered an entirely new kind of quantum entanglement." 2026: On Friday, February 6, "a control room full of scientists, administrators and members of the press gathered" at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab in Upton, New York to witness its final collisions, reports Scientific American: The vibe had been wistful, but the crowd broke into applause as Darío Gil, the Under Secretary for Science at the U.S. Department of Energy, pressed a red button to end the collider's quarter-century saga... "I'm really sad" [said Angelika Drees, a BNL accelerator physicist]. "It was such a beautiful experiment and my research home for 27 years. But we're going to put something even better there." That "something" will be a far more powerful electron-ion collider to further push the frontiers of physics, extend RHIC's legacy and maintain the lab's position as a center of discovery. This successor will be built in part from RHIC's bones, especially from one of its two giant, subterranean storage rings that once held the retiring collider's supply of circulating, near-light speed nuclei...slated for construction over the next decade. [That Electron-Ion Collider, or EIC] will utilize much of RHIC's infrastructure, replacing one of its ion rings with a new ring for cycling electrons. The EIC will use those tiny, fast-flying electrons as tiny knives for slicing open the much larger gold ions. Physicists will get an unrivaled look into the workings of quarks and gluons and yet another chance to grapple with nature's strongest force. "We knew for the EIC to happen, RHIC needed to end," says Wolfram Fischer, who chairs BNL's collider-accelerator department. "It's bittersweet." EIC will be the first new collider built in the US since RHIC. To some, it signifies the country's reentry into a particle physics landscape it has largely ceded to Europe and Asia over the past two decades. "For at least 10 or 15 years," says Abhay Deshpande, BNL's associate laboratory director for nuclear and particle physics, "this will be the number one place in the world for [young physicists] to come." The RHIC was able "to separately send two protons colliding with precisely aligned spins — something that, even today, no other experiment has yet matched," the article points out: During its record-breaking 25-year run, RHIC illuminated nature's thorniest force and its most fundamental constituents. It created the heaviest, most elaborate assemblages of antimatter ever seen. It nearly put to rest a decades-long crisis over the proton's spin. And, of course, it brought physicists closer to the big bang than ever before... When RHIC at last began full operations in 2000, its initial heavy-ion collisions almost immediately pumped out quark-gluon plasma. But demonstrating this beyond a shadow of a doubt proved in some respects more challenging than actually creating the elusive plasma itself, with the case for success strengthening as RHIC's numbers of collisions soared. By 2010 RHIC's scientists were confident enough to declare that the hot soup they'd been studying for a decade was hot and soupy enough to convincingly constitute a quark-gluon plasma. And it was even weirder than they thought. Instead of the gas of quarks and gluons theorists expected, the plasma acted like a swirling liquid unprecedented in nature. It was nearly "perfect," with zero friction, and set a new record for twistiness, or "vorticity." For Paul Mantica, a division director for the Facilities and Project Management Division in the DOE's Office of Nuclear Physics, this was the highlight of RHIC's storied existence. "It was paradigm-changing," he says... Data from the final run (which began nearly a year ago) has already produced yet another discovery: the first-ever direct evidence of "virtual particles" in RHIC's subatomic puffs of quark-gluon plasma, constituting an unprecedented probe of the quantum vacuum. RHIC's last run generated hundreds of petabytes of data, the article points out, meaning its final smash "isn't really the end; even when its collisions stop, its science will live on." But Science News notes RHIC's closure "marks the end for the only particle collider operating in the United States, and the only collider of its kind in the world. Most particle accelerators are unable to steer two particle beams to crash head-on into one another."

"After a half-century asking us to exercise more, doctors and physiologists say we have been thinking about it wrong," writes Washington Post columnist Michael J. Coren. "U.S. and World Health Organization guidelines no longer specify a minimum duration of moderate or vigorous aerobic activity." Movement-tracking studies show even tiny, regular bursts of effort — as short as 30 seconds — can capture many of the health benefits of the gym. Climbing two to three flights of stairs a few times per day could change your life. Experts call it VILPA, or vigorous intermittent lifestyle physical activity. "The message now is that all activity counts," said Martin Gibala, a professor and former chair of the kinesiology department at McMaster University in Canada... Just taking the stairs daily is associated with lower body weight and cutting the risk of stroke and heart disease — the leading (and largely preventable) cause of death globally. While it may not burn many calories (most exercise doesn't), it does appear to extend your health span. Leg power — a measure of explosive muscle strength — was a stronger predictor of brain aging than any lifestyle factors measured in a 2015 study in the journal Gerontology... How little activity can you do? Four minutes daily. Essentially, a few flights of stairs at a vigorous pace. That's the effort [Emmanuel Stamatakis, a professor of physical activity and population health at the University of Sydney] found delivered significant health benefits in that 2022 study of British non-exercisers. "We saw benefits from the first minute," Stamatakis said. For Americans, the effect is even more dramatic: a 44 percent drop in deaths, according to a peer-reviewed paper recently accepted for publication. "We showed for the first time that vigorous intensity, even if it's done as part of the day-to-day routine, not in a planned and structured manner, works miracles," Stamatakis said. "The key principle here is start with one, two minutes a day. The focus should be on making sure that it's something that you can incorporate into your daily routine. Then you can start thinking about increasing the dose." Intensity is the most important factor. You won't break a sweat in a brief burst, but you do need to feel it. A highly conditioned athlete might need to sprint to reach vigorous territory. But many people need only to take the stairs. Use your breathing as a guide, Stamatakis said: If you can sing, it's light intensity. If you can speak but not sing, you're entering moderate exertion. If you can't hold a conversation, it's vigorous. The biggest benefits come from moderate to vigorous movement. One minute of incidental vigorous activity prevents premature deaths, heart attacks or strokes as well as about three minutes of moderate activity or 35 to 49 minutes of light activity.

Fortune reports on "a watershed moment" in American's nuclear power industry: In January, Meta partnered with Gates' TerraPower and Sam Altman-backed Oklo to develop about 4 gigawatts of combined SMR projects — enough to power almost 3 million homes — for "clean, reliable energy" both for Meta's planned Prometheus AI mega campus in Ohio and beyond. Analysts see Meta as the start of more Big Tech nuclear construction deals — not just agreements with existing plants or restarts such as the now-Microsoft-backed Three Mile Island. "That was the first shot across the bow," said Dan Ives, head of tech research for Wedbush Securities, of the Meta deals. "I would be shocked if every Big Tech company doesn't make some play on nuclear in 2026, whether a strategic partnership or acquisitions." Ives pointed out there are more data centers under construction than there are active data centers in the U.S. "I believe clean energy around nuclear is going to be the answer," he said. "I think 2030 is the key threshold to hit some sort of scale and begin the next nuclear era in the United States." Smaller SMR reactors can be built in as little as three years instead of the decade required for traditional large reactors. And they can be expanded, one or two modular reactors at a time, to meet increasingly greater energy demand from 'hyperscalers,' the companies that build and operate data centers. "There's major risk if nuclear doesn't happen," Oklo chairman and CEO Jacob DeWitte told Fortune, citing the need for emission-free power and consistent baseload electricity to meet skyrocketing demand. "The hyperscalers, as the ultimate consumers of power are, are looking at the space and seeing that the market is real. They can play a major role in helping make that happen," DeWitte said, speaking in his fast-talking, Silicon Valley startup mode.

Axios reports: Anthropic's latest AI model has found more than 500 previously unknown high-severity security flaws in open-source libraries with little to no prompting, the company shared first with Axios. Why it matters: The advancement signals an inflection point for how AI tools can help cyber defenders, even as AI is also making attacks more dangerous... Anthropic debuted Claude Opus 4.6, the latest version of its largest AI model, on Thursday. Before its debut, Anthropic's frontier red team tested Opus 4.6 in a sandboxed environment [including access to vulnerability analysis tools] to see how well it could find bugs in open-source code... Claude found more than 500 previously unknown zero-day vulnerabilities in open-source code using just its "out-of-the-box" capabilities, and each one was validated by either a member of Anthropic's team or an outside security researcher... According to a blog post, Claude uncovered a flaw in GhostScript, a popular utility that helps process PDF and PostScript files, that could cause it to crash. Claude also found buffer overflow flaws in OpenSC, a utility that processes smart card data, and CGIF, a tool that processes GIF files. Logan Graham, head of Anthropic's frontier red team, told Axios they're considering new AI-powered tools to hunt vulnerabilities. "The models are extremely good at this, and we expect them to get much better still... I wouldn't be surprised if this was one of — or the main way — in which open-source software moving forward was secured."

Long-time Slashdot reader Geoffrey.landis shared this report from InsideEVs: Chinese battery giant CATL and automaker Changan Automobile are preparing to put the world's first passenger car powered by sodium-ion batteries on public roads by mid-2026. And if the launch is successful, it could usher in an era where electric vehicles present less of a fire risk and can better handle extreme temperatures. The CATL Naxtra sodium-ion battery will debut in the Changan Nevo A06 sedan, delivering an estimated range of around 400 kilometers (249 miles) on the China Light-Duty Test Cycle. From there, the battery will roll out across Changan's broader portfolio, including EVs from Avatr, Deepal, Qiyuan and Uni, the company said. "The launch represents a major step in the industry's transition toward a dual-chemistry ecosystem, where sodium-ion and lithium-ion batteries complement each other to meet diverse customer needs," CATL said in a press release... It delivers 175 watt-hours per kilogram of energy density, which is lower than nickel-rich chemistries but roughly on par with lithium ion phosphate batteries... Where the Naxtra battery really stands out, however, is cold-weather performance. CATL says its discharge power at -30 degrees Celsius (-22 degrees Fahrenheit) is three times higher than that of lithium ion phosphate batteries.

Has the rise of hyper-addictive digital technologies really shattered our attention spans and driven books out of our culture? Maybe not, argues social psychologist Adam Mastroianni (author of the Substack Experimental History): As a psychologist, I used to study claims like these for a living, so I know that the mind is primed to believe narratives of decline. We have a much lower standard of evidence for "bad thing go up" than we do for "bad thing go down." Unsurprisingly, then, stories about the end of reading tend to leave out some inconvenient data points. For example, book sales were higher in 2025 than they were in 2019, and only a bit below their high point in the pandemic. Independent bookstores are booming, not busting; at least 422 new indie shops opened in the United States last year alone. Even Barnes & Noble is cool again. The actual data on reading, meanwhile, isn't as apocalyptic as the headlines imply. Gallup surveys suggest that some mega-readers (11+ books per year) have become moderate readers (1-5 books per year), but they don't find any other major trends over the past three decades. Other surveys document similarly moderate declines. For instance, data from the National Endowment for the Arts finds a slight decrease in the percentage of U.S. adults who read any book in 2022 (49%) compared to 2012 (55%). And the American Time Use Survey shows a dip in reading time from 2003 to 2023. Ultimately, the plausibility of the "death of reading" thesis depends on two judgment calls. First, do these effects strike you as big or small...? The second judgment call: Do you expect these trends to continue, plateau, or even reverse...? There are signs that the digital invasion of our attention is beginning to stall. We seem to have passed peak social media — time spent on the apps has started to slide. App developers are finding it harder and harder to squeeze more attention out of our eyeballs, and it turns out that having your eyeballs squeezed hurts, so people aren't sticking around for it... Fact #2: Reading has already survived several major incursions, which suggests it's more appealing than we thought. Radio, TV, dial-up, Wi-Fi, TikTok — none of it has been enough to snuff out the human desire to point our pupils at words on paper... It is remarkable, even miraculous, that people who possess the most addictive devices ever invented will occasionally choose to turn those devices off and pick up a book instead. The author mocks the "death of reading" hypothesis for implying that all the world's avid readers "were just filling time with great works of literature until TikTok came along."

The New York Times lists other reasons a company lays off people. ("It didn't meet financial targets. It overhired. Tariffs, or the loss of a big client, rocked it...") "But lately, many companies are highlighting a new factor: artificial intelligence. Executives, saying they anticipate huge changes from the technology, are making cuts now." A.I. was cited in the announcements of more than 50,000 layoffs in 2025, according to Challenger, Gray & Christmas, a research firm... Investors may applaud such pre-emptive moves. But some skeptics (including media outlets) suggest that corporations are disingenuously blaming A.I. for layoffs, or "A.I.-washing." As the market research firm Forrester put it in a January report: "Many companies announcing A.I.-related layoffs do not have mature, vetted A.I. applications ready to fill those roles, highlighting a trend of 'A.I.-washing' — attributing financially motivated cuts to future A.I. implementation...." "Companies are saying that 'we're anticipating that we're going to introduce A.I. that will take over these jobs.' But it hasn't happened yet. So that's one reason to be skeptical," said Peter Cappelli, a professor at the Wharton School... Of course, A.I. may well end up transforming the job market, in tech and beyond. But a recent study... [by a senior research fellow at the Brookings Institution who studies A.I. and work] found that AI has not yet meaningfully shifted the overall market. Tech firms have cut more than 700,000 employees globally since 2022, according to Layoffs.fyi, which tracks industry job losses. But much of that was a correction for overhiring during the pandemic. As unpopular as A.I. job cuts may be to the public, they may be less controversial than other reasons — like bad company planning. Amazon CEO Jassy has even said the reason for most of their layoffs was reducing bureaucracy, the article points out, although "Most analysts, however, believe Amazon is cutting jobs to clear money for A.I. investments, such as data centers."

Phoronix reports: Chris Mason, the longtime Linux kernel developer most known for being the creator of Btrfs, has been working on a Git repository with AI review prompts he has been working on for LLM-assisted code review of Linux kernel patches. This initiative has been happening for some weeks now while the latest work was posted today for comments... The Meta engineer has been investing a lot of effort into making this AI/LLM-assisted code review accurate and useful to upstream Linux kernel stakeholders. It's already shown positive results and with the current pace it looks like it could play a helpful part in Linux kernel code review moving forward. "I'm hoping to get some feedback on changes I pushed today that break the review up into individual tasks..." Mason wrote on the Linux kernel mailing list. "Using tasks allows us to break up large diffs into smaller chunks, and review each chunk individually. This ends up using fewer tokens a lot of the time, because we're not sending context back and forth for the entire diff with every turn. It also catches more bugs all around."

California-based Karman Industries "says it has developed a cooling system that uses SpaceX rocket engine technology to rein in the environmental impact of data centers," reports the Los Angeles Times, "chilling them with less space, less power and no water." Karman has developed a cooling system similar to the heat pumps in the average home, except its pumps use liquid carbon dioxide as refrigerant, which is circulated using rocket engine technology rather than fans. The company's efficient pumps can reduce the space required for data center cooling equipment by 80%. Over the years, data centers have used fans and air conditioning to blow cold air on the chips. Bigger facilities pass cold liquid through tubes near the chips to absorb the heat. This hot liquid is sent outside to a cooling yard, where sprawling networks of pipes use as much water as a city of 50,000 people to remove the heat. A 50 megawatt data center also uses enough electricity to power a mid-sized city... Cooling systems account for up to 40% of a data center's power consumption and an average midsized data center consumes more than 35,000 gallons of water per day... U.S. data centers will consume about 8% of all electricity in the country by 2030, according to the International Energy Agency... The cooling systems are projected to use up to 33 billion gallons of water by 2028 per year... To serve this seemingly insatiable market, Karman has developed a rotating compressor that spins at 30,000 revolutions per minute — nearly 10 times faster than traditional compressors — to move heat... About a third of Karman's 23-person team came from SpaceX or Rocket Lab, and they co-opted technologies from aerospace engineering and electric vehicles to design the mechanics for the high-speed motors. The system uses a special type of carbon dioxide under high pressure to transfer heat from the data center to the outside air. Depending on the conditions, it can do the same amount of cooling using less than half the energy. Karman's heat pump can either reject heat to air, or route it into extra cooling, or even power generation. The company "recently raised $20 million," according to the article, "and expects to start building its first compressors in Long Beach later this year...."

Brax Technologies just announced "a privacy-focused alternative to locked-down tablets" called open_slate that can double as a consumer tablet and a Linux-capable workstation on ARM. Earlier Brax Technologies built the privacy-focused smartphone BraX3, which co-founder Plamen Todorov says proved "a privacy-focused mobile device could be designed, crowdfunded, manufactured, and delivered outside the traditional Big Tech ecosystem." Just as importantly, BraX3 showed us the value of building with the community. The feedback we received — what worked, what didn't, and what people wanted next — played a major role in shaping our direction going forward. Today, we're ready to share the next step in that journey... They're promising their "2-in-1" open_slate tablet will be built with these guiding principles: Modularity beyond repairability". ("In addition to a user-replaceable battery, it supports an M.2 expansion slot, allowing users to customize storage and configurations to better fit their needs.") Hardware-level privacy and control, with physical switches allowing users to disable key components like wireless radios, sensors, microphones, and cameras. Multi-OS compatibility, supporting "multiple" Android-based operating systems as well as native Linux distributions. ("We're working with partners and the community to ensure proper, long-term OS support rather than one-off ports.") Longevity by design — a tablet that's "supported over time" Brax has already created an open thread with preliminary design specs. "The planned retail price is 599$ for the base version and 799$ for the Pro version," they write. "We will be offering open_slate (both versions) at a discount during our pre-order campaign, starting as low as 399$ for the base version and 529$ for the Pro version for limited quantities only which may sell out in a day or two from launching pre-orders... "Pre-orders will open in February, via IndieGoGo. Make sure to subscribe for notifications if you don't want to miss the launch date." Thanks to long-time Slashdot reader walterbyrd for sharing the news.

KDE's "Plasma Login Manager" is apparently dropping support for FreeBSD, the Unix-like operating system, reports the blog It's FOSS. They cite a recently-accepted merge request from a KDE engineer to drop the code supporting FreeBSD, since the login manager relies on systemd/logind: systemd and logind look like hard dependencies of the login manager, which means the software is built to work exclusively with these components and cannot function without them... logind is a component of systemd that is responsible for user session management... This doesn't mean that KDE has abandoned the operating system altogether. FreeBSD users can still run the KDE Plasma desktop environment and continue using SDDM, the current login manager that works just fine on such systems. The article argues FreeBSD users "won't really care much for missing out on this as they have plenty of login manager options available."

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) writes: Washington State lawmakers are proposing bills (HB 2320 and HB 2321) that would require 3D printers and CNC machines to block certain designs using software-based "firearms blueprint detection algorithms." In practice, this means scanning every print file, comparing it against a government-maintained database, and preventing "skilled users" from bypassing the system. Supporters frame this as a response to untraceable "ghost guns," but even federal prosecutors admit the tools involved are ordinary manufacturing equipment. Critics warn the language is overbroad, technically unworkable, hostile to open source, and likely to push printing toward cloud-locked, subscription-based systems—while doing little to stop criminals.

An anonymous reader shared this report from The Verge: In early December, I brought you the news that Google has begun replacing Verge headlines, and those of our competitors, with AI clickbait nonsense in its content feed [which appears on the leftmost homescreen page of many Android phones and the Google app's homepage]. Google appeared to be backing away from the experiment, but now tells The Verge that its AI headlines in Google Discover are a feature, one that "performs well for user satisfaction." I once again see lots of misleading claims every time I check my phone... For example, Google's AI claimed last week that "US reverses foreign drone ban," citing and linking to this PCMag story for the news. That's not just false — PCMag took pains to explain that it's false in the story that Google links to...! What does the author of that PCMag story think? "It makes me feel icky," Jim Fisher tells me over the phone. "I'd encourage people to click on stories and read them, and not trust what Google is spoon-feeding them." He says Google should be using the headline that humans wrote, and if Google needs a summary, it can use the ones that publications already submit to help search engines parse our work. Google claims it's not rewriting headlines. It characterizes these new offerings as "trending topics," even though each "trending topic" presents itself as one of our stories, links to our stories, and uses our images, all without competent fact-checking to ensure the AI is getting them right... The AI is also no longer restricted to roughly four words per headline, so I no longer see nonsense headlines like "Microsoft developers using AI" or "AI tag debate heats." (Instead, I occasionally see tripe like "Fares: Need AAA & AA Games" or "Dispatch sold millions; few avoided romance.") But Google's AI has no clue what parts of these stories are new, relevant, significant, or true, and it can easily confuse one story for another. On December 26th, Google told me that "Steam Machine price & HDMI details emerge." They hadn't. On January 11th, Google proclaimed that "ASUS ROG Ally X arrives." (It arrived in 2024; the new Xbox Ally arrived months ago.) On January 20th, it wrote that "Glasses-free 3D tech wows," introducing readers to "New 3D tech called Immensity from Leia" — but linking to this TechRadar story about an entirely different company called Visual Semiconductor... Google declined our request for an interview to more fully explain the idea. The site Android Police spotted more inaccurate headlines in December: A story from 9to5Google, which was actually titled 'Don't buy a Qi2 25W wireless charger hoping for faster speeds — just get the 'slower' one instead' was retitled as 'Qi2 slows older Pixels.' Similarly, Ars Technica's 'Valve's Steam Machine looks like a console, but don't expect it to be priced like one' was changed to 'Steam Machine price revealed.' At the time, we believed that the inaccuracies were due to the feature being unstable and in early testing.... Now, Google has stopped calling Discover replacing human-written headlines as an "experiment." "Google buries a 'Generated with AI, which can make mistakes' message under the 'See more' button in the summary," reports 9to5Google, "making it look like this is the publisher's intended headline." While it is obvious that Google has refined this feature over the past couple of months, it doesn't take long to still find plenty of misleading headlines throughout Discover... Another article from NotebookCheck about an Anker power bank with a retractable cable was given a headline that's about another product entirely. A pair of headlines from Tom's Hardware and PCMag, meanwhile, show the two sides of using AI for this purpose. The Tom's Hardware headline, "Free GPU & Amazon Scams," isn't representative of the actual article, which is about someone who bought a GPU from Amazon, canceled their order, and the retailer shipped it anyway. There's nothing about "Amazon Scams" in the article.
