Longtime Slashdot reader SchroedingersCat writes: Chuck Norris, known for his roles in action films and as Texas Ranger Cordell Walker on the TV show "Walker, Texas Ranger," passed away on March 19, leaving behind a legacy of inspiring millions around the world. He was 86.

He became Internet phenomenon after "Chuck Norris Facts" went viral online with such wildly hyperbolic statements as, "Chuck Norris had a staring contest with the sun -- and won," and, "When Chuck Norris does push-ups, he doesn't push himself up, he pushes the Earth down."

His death was announced by his family through his official Instagram account, but no further details were immediately available. He was hospitalized earlier that day in Hawaii after experiencing a medical emergency, the family said.

An anonymous reader quotes a report from Ars Technica: Google is planning big changes for Android in 2026 aimed at combating malware across the entire device ecosystem. Starting in September, Google will begin restricting application sideloading with its developer verification program, but not everyone is on board. Android Ecosystem President Sameer Samat tells Ars that the company has been listening to feedback, and the result is the newly unveiled advanced flow, which will allow power users to skip app verification. With its new limits on sideloading, Android phones will only install apps that come from verified developers. To verify, devs releasing apps outside of Google Play will have to provide identification, upload a copy of their signing keys, and pay a $25 fee. It all seems rather onerous for people who just want to make apps without Google's intervention.

Apps that come from unverified developers won't be installable on Android phones -- unless you use the new advanced flow, which will be buried in the developer settings. When sideloading apps today, Android phones alert the user to the "unknown sources" toggle in the settings, and there's a flow to help you turn it on. The verification bypass is different and will not be revealed to users. You have to know where this is and proactively turn it on yourself, and it's not a quick process. [...] The actual legwork to activate this feature only takes a few seconds, but the 24-hour countdown makes it something you cannot do spur of the moment.

But why 24 hours? According to Samat, this is designed to combat the rising use of high-pressure social engineering attacks, in which the scammer convinces the victim they have to install an app immediately to avoid severe consequences. "In that 24-hour period, we think it becomes much harder for attackers to persist their attack," said Samat. "In that time, you can probably find out that your loved one isn't really being held in jail or that your bank account isn't really under attack." But for people who are sure they don't want Google's verification system to get in the way of sideloading any old APK they come across, they don't have to wait until they encounter an unverified app to get started. You only have to select the "indefinitely" option once on a phone, and you can turn dev options off again afterward. "For a lot of people in the world, their phone is their only computer, and it stores some of their most private information," Samat said. "Over the years, we've evolved the platform to keep it open while also keeping it safe. And I want to emphasize, if the platform isn't safe, people aren't going to use it, and that's a lose-lose situation for everyone, including developers."

Kyle Orland writes via Ars Technica: Since deep-learning super-sampling (DLSS) launched on 2018's RTX 2080 cards, gamers have been generally bullish on the technology as a way to effectively use machine-learning upscaling techniques to increase resolutions or juice frame rates in games. With yesterday's tease of the upcoming DLSS 5, though, Nvidia has crossed a line from mere upscaling into complete lighting and texture overhauls influenced by "generative AI." The result is a bland, uncanny gloss that has received an instant and overwhelmingly negative reaction from large swaths of gamers and the industry at large.

While previous DLSS releases rendered upscaled frames or created entirely new ones to smooth out gaps, Nvidia calls DLSS 5 -- which it plans to launch in Autumn -- "a real-time neural rendering model" that can "deliver a new level of photoreal computer graphics previously only achieved in Hollywood visual effects." Nvidia CEO Jensen Huang said explicitly that the technology melds "generative AI" with "handcrafted rendering" for "a dramatic leap in visual realism while preserving the control artists need for creative expression."

Unlike existing generative video models, which Nvidia notes are "difficult to precisely control and often lack predictability," DLSS 5 uses a game's internal color and motion vectors "to infuse the scene with photoreal lighting and materials that are anchored to source 3D content and consistent from frame to frame." That underlying game data helps the system "understand complex scene semantics such as characters, hair, fabric and translucent skin, along with environmental lighting conditions like front-lit, back-lit or overcast," the company says. Nvidia's announcement video and detailed Digital Foundry breakdown can be found at their respective links.

"Reactions have compared the effect to air-brushed pornography, 'yassified, looks-maxed freaks,' or those uncanny, unavoidable Evony ads," writes Orland. "Others have noted how DLSS 5 seems to mangle the intended art direction by dampening shadows in favor of a homogenized look."

Thomas Was Alone developer Mike Bithell said the technology seems designed "for when you absolutely, positively, don't want any art direction in your gaming experience."

Gunfire Games Senior Concept Artist Jeff Talbot added that "in every shot the art direction was taken away for the senseless addition of 'details.' Each DLSS 5 shot looked worse and had less character than the original. This is just a garbage AI Filter."

DLSS 5's "AI dogshit is actually depressing," said New Blood Interactive founder and CEO Dave Oshry, adding that future generations "won't even know this looks 'bad' or 'wrong' because to them it'll be normal."

The UK's science minister is announcing details of a five-year, £2.5 billion investment in nuclear fusion, reports the Times of London, "including building one of the world's first prototype fusion power plants in Nottinghamshire and developing a UK sector projected to employ 10,000 people by 2030." Despite the potentially transformative impact of fusion, which in theory could provide limitless clean energy and create a £12 trillion global market, no country has managed to use this fledgling technology to generate useable electricity... [T]he UK is backing a spherical tokamak design... investing an initial £1.3 billion into a prototype fusion power plant called Step (Spherical Tokamak for Energy Production) on the site of a decommissioned coal-fired power station at West Burton in Nottinghamshire. Paul Methven, chief executive of the government-owned UK Industrial Fusion Solutions, which is delivering the Step project, said the aim is to get the reactor operating early in the 2040s. "It's quite an aggressive programme," he said. "We need to show that we can achieve genuine 'wall socket' energy — which has not been done before."

On Monday, [science minister] Vallance will also announce £180 million for a facility in Culham, Oxfordshire, to manufacture tritium fuel and £50 million for training 2,000 scientists and engineers in fusion-related disciplines. The government is also buying a £45 million fusion-dedicated AI supercomputer called Sunrise to model plasma physics. Scientists at the UK Atomic Energy Authority last year developed an AI model that can rapidly simulate how the ultra-hot fuel in a fusion power plant will behave, cutting calculations that previously took days down to seconds...

Vallance will also announce new support and collaboration for the many fusion, robotics, engineering and AI start-ups working in Britain, to develop a strong supply chain for a new fusion sector. One of those companies, Tokamak Energy, which spun out from the UK Atomic Energy Authority in 2009, has already built a smaller reactor that has informed the Step design. In March 2022, it became the first private organisation in the world to surpass 100 million degrees Celsius in its reactor.

Plug-in (or "balcony") solar panels can also be hung out a window or be set up in a backyard, reports NPR. They channel energy from the sun straight into a home's electrical outlet, generating enough electricity to power a refrigerator or microwave while "displacing electricity that otherwise would come in from the grid..."

But what's holding up their adoption in America? For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. Utah enacted the first law, last May, supporting plug-in solar, and now some 30 pieces of similar legislation have been introduced around the United States. [And Virginia seems poised to pass a similar law.]

But the drive toward plug-in solar is facing pushback from electric utilities. They are raising safety concerns and prompting legislators to delay votes on the bills. So far, utilities have won over lawmakers in five states and convinced them to delay votes on plug-in solar bills... Plug-in solar advocates say that safety concerns about the new technology have been addressed and that utilities are really just worried about losing business, because every kilowatt-hour generated by a plug-in solar panel is one less the utility sells to a customer... There are safety risks with any electrical appliance, and it's true that plug-in solar panels present some unique problems. But safety experts also say those issues can be managed....

German utilities expressed many of the same concerns nearly a decade ago when plug-in solar started to become popular in Germany. But with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy.

An anonymous reader quotes a report from the Guardian: AI has made it vastly easier for malicious hackers to identify anonymous social media accounts, a new study has warned. In most test scenarios, large language models (LLMs) -- the technology behind platforms such as ChatGPT -- successfully matched anonymous online users with their actual identities on other platforms, based on the information they posted. The AI researchers Simon Lermen and Daniel Paleka said LLMs make it cost effective to perform sophisticated privacy attacks, forcing a "fundamental reassessment of what can be considered private online".

In their experiment, the researchers fed anonymous accounts into an AI, and got it to scrape all the information it could. They gave a hypothetical example of a user talking about struggling at school, and walking their dog Biscuit through a "Dolores park." In that hypothetical case, the AI then searched elsewhere for those details and matched @anon_user42 to the known identity with a high degree of confidence. While this example was fictional, the paper's authors highlighted scenarios in which governments use AI to surveil dissidents and activists posting anonymously, or hackers are able to launch "highly personalized" scams.

An anonymous reader quotes a report from CBS News: Tonight, we have details of a classified U.S. intelligence mission that has obtained a previously unknown weapon that may finally unlock a mystery. Since at least 2016, U.S. diplomats, spies and military officers have suffered crippling brain injuries. They've told of being hit by an overwhelming force, damaging their vision, hearing, sense of balance and cognition. but the government has doubted their stories. They've been called delusional. Well now, 60 Minutes has learned that a weapon that can inflict these injuries was obtained overseas and secretly tested on animals on a U.S. military base. We've investigated this mystery for nine years. This is our fourth story called, "Targeting Americans." Despite official government doubt, we never stopped reporting because of the haunting stories we heard [...]. 60 Minutes interviewed Dr. David Relman, a scientific expert and professor from Stanford University who was tasked by the government to lead two investigations into the Havana Syndrome cases. What he and his panel of doctors, physicists, engineers and others found was that "the most plausible explanation for a subset of these cases was a form of radiofrequency or microwave energy," the report says.

According to confidential sources cited in the report, undercover Homeland Security agents bought a miniaturized microwave weapon from a Russian criminal network in 2024 and tested it on animals at a U.S. military lab. The injuries reportedly matched those seen in the human cases. "Our confidential sources tell us the still classified weapon has been tested in a U.S. military lab for more than a year," says Dr. Relman. "Tests on rats and sheep show injuries consistent with those seen in humans."

He continues: "Also, as a separate part of the investigation, security camera videos have been collected that show Americans being hit. The videos are classified but they were described to us. In one, a camera in a restaurant in Istanbul captured two FBI agents on vacation sitting at a table with their families. A man with a backpack walks in and suddenly everyone at the table grabs their head as if in pain. Our sources say another video comes from a stairwell in the U.S. embassy in Vienna. The stairs lead to a secure facility. In the video, two people on the stairs suddenly collapse. Those videos and the weapon were among the reasons the Biden administration summoned about half a dozen victims to the White House with about two months left in the president's term."

Former intelligence officials and researchers claim elements of the U.S. government downplayed or dismissed the theory for years, possibly to avoid political consequences of accusing a foreign state like Russia of conducting attacks on American personnel.

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.

"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.

A Florida woman was sentenced to 22 months in federal prison and fined $50,000 for illegally trafficking thousands of Microsoft certificate-of-authenticity labels used to activate Windows and Office. Prosecutors said she bought genuine labels cheaply from suppliers and resold them without the accompanying licensed software, wiring over $5 million during the scheme. TechRadar reports: The indictment details how [52-year-old Heidi Richards] purchased tens of thousands of genuine COA labels from a Texas-based supplier between 2018 and 2023 for well below the retail value, before reselling them in bulk to customers globally without the licensed software. "COA labels are not to be sold separately from the license and hardware that they are intended to accompany, and they hold no independent commercial value," the US Attorney's Office wrote.

Richards was found to have wired $5,148,181.50 to the unnamed Texas company during the scheme's operation. Some examples include the purchase of 800 Windows 10 COA labels in July 2018 for $22,100 (under $28 each) and a further 10,000 Windows 10 Pro COA labels in December 2022 for $200,000 ($20 each). Ultimately fined $50,000 and given a near-two-year sentence, prosecutors had sought to get Richards to pay $242,000, "which represents the proceeds obtained from the offenses."

An anonymous reader quotes a report from 80 Level: Microsoft has officially confirmed development of its next-generation Xbox console, currently known internally as Project Helix. While concrete details remain limited, early information suggests the company is positioning the device as a hybrid between a traditional console and a gaming PC, capable of running both Xbox titles and PC games. The codename was revealed recently by new Xbox CEO Asha Sharma, who reaffirmed Microsoft's continued commitment to dedicated gaming hardware despite speculation that the company might shift entirely toward cloud or platform-based ecosystems. According to Sharma, Project Helix represents the next step in Xbox's console strategy.

Although official specifications have not yet been announced, early reports indicate the system will likely rely on a new AMD system-on-chip combining Xbox hardware with PC-style architecture. The device is expected to emphasize high performance while maintaining compatibility with existing Xbox game libraries. [...] If the concept holds, Project Helix could mark a significant shift in how console ecosystems are structured, moving away from tightly closed hardware platforms toward something closer to a unified PC-console environment. Sharma wrote in a post on X: "Great start to the morning with Team Xbox, where we talked about our commitment to the return of Xbox, including Project Helix, the code name for our next generation console. Project Helix will lead in performance and play your Xbox and PC games. Looking forward to chatting about this more with partners and studios at my first GDC next week!"

joshuark writes: The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a VMware Aria Operations vulnerability tracked as CVE-2026-22719 to its Known Exploited Vulnerabilities catalog, flagging the flaw as exploited in attacks. VMware Aria Operations is an enterprise monitoring platform that helps organizations track the performance and health of servers, networks, and cloud infrastructure. The flaw has now been added to the CISA's Known Exploited Vulnerabilities (KEV) catalog, with the U.S. cyber agency requiring federal civilian agencies to address the issue by March 24, 2026. Broadcom said it is aware of reports indicating the vulnerability is exploited in attacks but cannot confirm the claims.

"A malicious unauthenticated actor may exploit this issue to execute arbitrary commands which may lead to remote code execution in VMware Aria Operations while support-assisted product migration is in progress," the advisory explains. Broadcom released security patches on February 24 and also provided a temporary workaround for organizations unable to apply the patches immediately. The mitigation is a shell script named "aria-ops-rce-workaround.sh," which must be executed as root on each Aria Operations appliance node. There are currently no details on how the vulnerability is being exploited in the wild, who is behind it, and the scale of such efforts.

Google is eliminating its traditional 30% Play Store fee and introducing lower commissions, while at the same time allowing alternative billing systems and making it easier for third-party app stores to operate on Android. The changes stem largely from Google's settlement with Epic Games. Engadget reports: The biggest change is to how Google will collect fees from developers publishing apps on Android. Rather than take its standard 30 percent cut of in-app purchases through the Play Store, Google is lowering its cut to 20 percent, and in some cases 15 percent for new installs of apps from developers participating in its new App Experience program or updated Google Play Games Level Up program. Those changes extend to subscriptions, too, where the company's cut is lowering to 10 percent. For Google's billing system, the company says developers in the UK, US, or European Economic Area (EEA) will now be charged a five percent fee and "a market-specific rate" in other regions. Of course, for anyone trying to avoid those fees, using alternatives to Google's billing system is getting easier.

Google says that developers will be able to offer alternative billing systems alongside its own or "guide users outside of their app to their own websites for purchases." [...] Epic is ultimately interested in getting people to use the mobile version of its Epic Games Store, and Google's announcement also includes details on how third-party app stores can come to Android. Third-party app stores will be able to apply to the company's new "Registered App Stores" program to see if they meet "certain quality and safety benchmarks." If they do, they'll be able to take advantage of a streamlined installation interface in Android. Participating in the program is optional, and users will still be able to sideload alternative app stores that aren't part of the program, but Google clearly has a preference. [...]

Google says that its updated fee structure will come to the EEA, the UK and the US by June 30, Australia by September 30, Korea and Japan by December 31 and the entire world by September 30, 2027. Meanwhile, the company's updated Google Play Games Level Up program and new App Experience program will launch in the EEA, the UK, the US and Australia on September 30, before hitting the remaining regions alongside the updated fee structure. For any developers interested in offering their own app store, Google says it'll launch its Registered App Stores program "with a version of a major Android release" before the end of the year. According to the company, the program will be available in other regions first before it comes to the US.

A new Android app called Nearby Glasses alerts users when Bluetooth signals from smart glasses are detected nearby. The Android app, called Nearby Glasses, "launches at a time as there is an increasing resistance against always-recording or listening devices, which critics say process information about nearby people who do not give their consent," reports TechCrunch. From the report: Yves Jeanrenaud, who made the app, first spoke to 404 Media about the project and said he was in part inspired to make Nearby Glasses after reading the independent publication's reporting into wearable surveillance devices, including how Meta's Ray-Ban smart glasses have been used in immigration raids and to film and harass sex workers.

On the app's project page, Jeanrenaud described smart glasses as an "intolerable intrusion, consent neglecting, horrible piece of tech." Jeanrenaud told TechCrunch in an email that his motivation came from "witnessing the sheer scale and inhumane nature of the abuse these smart glasses are involved in." Jeanrenaud also cited Meta's decision to implement face recognition as a default feature in its smart glasses, "which I consider to be a huge floodgate pushed open for all kinds of privacy-invasive behavior."

The app works by listening for nearby Bluetooth signals that contain a publicly assigned identifier unique to the Bluetooth device's manufacturer. If the app detects a Bluetooth signal from a nearby hardware device made by Meta or Snap, the app will send the user an alert. (The app also allows users to add their own specific Bluetooth identifiers, allowing the user to detect a broader range of wearable surveillance gadgetry.)

Dustin Destree shares a report from Phys.org: Although plastic particles in the air are increasingly coming into focus, knowledge about their distribution and effects is still limited. Chemical analyses from Leipzig now provide details from Germany for the first time: Around 4% of the particulate matter consists of plastic. Around two-thirds of this comes from tire abrasion. Extrapolated, this means that people in a city like Leipzig inhale approximately 2.1 micrograms of plastic per day through the air, which increases the risk of death from cardiovascular disease by 9% and from lung cancer by 13%. These findings underscore the need to take global action against plastic pollution and to examine air quality and health at the regional level, write researchers from the Leibniz Institute for Tropospheric Research (TROPOS) and Carl von Ossietzky University of Oldenburg in the journal Communications Earth & Environment. "With around two-thirds of microplastics coming from tire abrasion, this shows that action is needed and that the fine dust problem cannot be solved by switching to electric mobility alone. To protect health, it would be important to also take tire abrasion into account when regulating air quality and to set limits for microplastics in the air," demands Prof. Hartmut Herrmann from TROPOS, who led the study.

The study has been published in the journal Communications Earth & Environment.

Google is accelerating Chrome's major release cadence from four weeks to two starting with version 153 on September 8th. "...our goal is to ensure developers and users have immediate access to the latest performance improvements, fixes and new capabilities," says Google. "Building on our history of adapting our release process to match the demands of a modern web, Chrome is moving to a two-week release cycle." The company says the "smaller scope" of these releases "minimizes disruption and simplifies post-release debugging." They also cite "recent process enhancements" that will "maintain [Chrome's] high standards for stability." 9to5Google reports: There will still be weekly security updates between milestones. This applies to desktop, Android, and iOS, while there are "no changes to the Dev and the Canary channels": "A Chrome Beta for each version will ship three weeks before the stable release. We recommend developers test with the beta to keep up to date with any upcoming changes that might impact your sites and applications."

The eight-week Extended Stable release schedule for enterprise customers and Chromium embedders will not change. Chromebooks will also have "extended release options": "Our priority is a seamless experience, so the latest Chrome releases will roll out to Chromebooks after dedicated platform testing. We are adapting these channels for the new two-week browser cycle and we will share more details soon regarding milestone updates for managed devices."

Today, Apple updated the MacBook Pro and MacBook Air with support for its new M5 chips. It also unveiled a pair of all-new Studio Display XDR monitors. Longtime Slashdot reader jizmonkey shares details about the M5 Pro and M5 Max chips, which look to be fairly major updates from the previous generation: Apple announced its newest CPUs today, which it claims has the fastest single-threaded performance in the world. Both the M5 Pro and M5 Max have eighteen-core designs, versus twelve or fourteen in the M4 Pro and fourteen or sixteen in the M4 Max. However, the number of higher-performing cores has been reduced significantly. In the older M4 designs, the chips had eight, ten, or twelve "performance" cores and four "efficiency" cores. In the M5 design, there are now only six higher-performing cores (now called "super" cores) and twelve lower-performing cores (now called "performance" cores). [Apple positions this "reduction" as a redesigned architecture with new core types.] The maximum amount of RAM remains the same at 128GB for the M5 Max (64GB for the M5 Pro), and GPU performance has increased. [The M5 Pro features up to a 20-core GPU, while the M5 Max scales up to 40 cores, each equipped with a Neural Accelerator. Apple also says the new architecture delivers over 4x peak GPU compute for AI compared to the previous generation, along with up to 35 percent faster performance in ray-traced graphics workloads.] Laptops with the new chips are available to order starting tomorrow and will be delivered starting March 11. As for the new XDR monitors, MacRumors highlights some of the key features in its reporting: Apple today introduced an all-new Studio Display XDR monitor with a 27-inch screen, mini-LED backlighting, 5K resolution, peak brightness of 2,000 nits for HDR content, up to a 120Hz refresh rate, Thunderbolt 5, and more. The new Studio Display XDR replaces Apple's former Pro Display XDR, which has been discontinued. Going forward, there are now two Studio Display models.

Both new Studio Display models have the same overall design as the original model. Both models have a 12-megapixel Center Stage camera, but it now supports Desk View on the new models. Both models also feature an upgraded six-speaker system, with Apple advertising "30 percent deeper bass" compared to the previous model. Only the higher-end Studio Display XDR received a 120Hz refresh rate, mini-LED backlighting, increased brightness, and faster 140W pass-through charging. The regular Studio Display still has a 60Hz refresh rate and up to 600 nits of brightness. Both models have 27-inch displays with a 5K resolution.

The new Studio Displays can be pre-ordered starting Wednesday, March 4, ahead of a Wednesday, March 11 launch. In the U.S., the regular Studio Display continues to start at $1,599, while the Studio Display XDR starts at $3,299.

Researchers at Cortical Labs used living human neurons grown on a chip to learn how to play Doom in about a week. "While its performance is not up to par with humans, experts say it brings biological computers a step closer to useful real-world applications, like controlling robot arms," reports New Scientist. From the report: In 2021, the Australian company Cortical Labs used its neuron-powered computer chips to play Pong. The chips consisted of clumps of more than 800,000 living brain cells grown on top of microelectrode arrays that can both send and receive electrical signals. Researchers had to carefully train the chips to control the paddles on either side of the screen. Now, Cortical Labs has developed an interface that makes it easier to program these chips using the popular programming language Python. An independent developer, Sean Cole, then used Python to teach the chips to play Doom, which he did in around a week.

"Unlike the Pong work that we did a few years ago, which represented years of painstaking scientific effort, this demonstration has been done in a matter of days by someone who previously had relatively little expertise working directly with biology," says Brett Kagan of Cortical Labs. "It's this accessibility and this flexibility that makes it truly exciting."

The neuronal computer chip, which used about a quarter as many neurons as the Pong demonstration, played Doom better than a randomly firing player, but far below the performance of the best human players. However, it learnt much faster than traditional, silicon-based machine learning systems and should be able to improve its performance with newer learning algorithms, says Kagan. However, it's not useful to compare the chips with human brains, he says. "Yes, it's alive, and yes, it's biological, but really what it is being used as is a material that can process information in very special ways that we can't recreate in silicon." Cortical Labs posted a YouTube video showing its CL1 biological computer running Doom. There's also source code available on GitHub, with additional details in a README file.

An anonymous reader quotes a report from the Associated Press: Anthropic CEO Dario Amodei said Thursday the artificial intelligence company "cannot in good conscience accede" to the Pentagon's demands to allow wider use of its technology. The maker of the AI chatbot Claude said in a statement that it's not walking away from negotiations, but that new contract language received from the Defense Department "made virtually no progress on preventing Claude's use for mass surveillance of Americans or in fully autonomous weapons."

The Pentagon's top spokesman has reiterated that the military wants to use Anthropic's artificial intelligence technology in legal ways and will not let the company dictate any limits ahead of a Friday deadline to agree to its demands. Sean Parnell said Thursday on social media that the Pentagon "has no interest in using AI to conduct mass surveillance of Americans (which is illegal) nor do we want to use AI to develop autonomous weapons that operate without human involvement."

Anthropic's policies prevent its models, such as its chatbot Claude, from being used for those purposes. It's the last of its peers -- the Pentagon also has contracts with Google, OpenAI and Elon Musk's xAI -- to not supply its technology to a new U.S. military internal network. Parnell said the Pentagon wants to "use Anthropic's model for all lawful purposes" but didn't offer details on what that entailed. He said opening up use of the technology would prevent the company from "jeopardizing critical military operations." "We will not let ANY company dictate the terms regarding how we make operational decisions," he said. In a post on X, Parnell said Anthropic will "have until 5:01 PM ET on Friday to decide. Otherwise, we will terminate our partnership with Anthropic and deem them a supply chain risk for DOW."

An anonymous reader quotes a report from the Financial Times: Officials working with Donald Trump's "Board of Peace" are exploring setting up a stablecoin for Gaza as part of efforts to reshape the devastated Palestinian enclave's economy, according to five people familiar with the discussions. The talks around introducing a stablecoin -- a type of cryptocurrency whose value is pegged to a mainstream currency, such as the US dollar -- are at a preliminary stage, and many details of how one could be introduced in Gaza remain to be determined.

But officials have discussed the idea as part of their plan for the future of the enclave, where economic activity collapsed during Israel's two-year war with Hamas and the traditional banking and payments system has been severely impaired. A person familiar with the project said the stablecoin was expected to be tied to the US dollar, with the hope that Gulf Arab and Palestinian companies with expertise in the field of digital currencies will help spearhead the effort. "This will not be a 'Gaza Coin' or a new Palestinian currency, but a means to allow Gazans to transact digitally," the person said.

Work on the idea is being led by Liran Tancman, an Israeli tech entrepreneur and former reservist who is now working as an unpaid adviser to Trump's "Board of Peace," the US-led body tasked with rebuilding Gaza, according to two people familiar with the matter. [...] According to the person familiar with the project, the "Board of Peace" and NCAG will decide on the stablecoin's regulatory framework and access, although "nothing definitive" has yet been finalized. Speaking at a meeting of the "Board of Peace" in Washington last week, Tancman said the NCAG was working on building "a secure digital backbone, an open platform enabling e-payments, financial services, e-learning, and healthcare with user control over data", but did not elaborate.
