The Washington Post looks at a new kind of battery that "could make American EVs cheaper and safer, experts say." If you bought an EV with a lithium iron phosphate (LFP) battery, you could expect lower car payments, less fire risk and more years of use out of your car — but you wouldn't be able to go as far on a single charge as you could with the nickel manganese cobalt (NMC) batteries commonly found in American and European electric cars. That trade-off has made LFP batteries the go-to choice for standard-range EVs in China, helping to make electric cars more affordable and limit pollution. Now, American companies are starting to build their own LFP batteries to catch up to their Chinese rivals... But there are plenty of barriers for U.S. companies that want to adopt a technology dominated by Chinese firms. Tariffs and tax credit restrictions have made it too expensive for most American automakers to import LFP batteries from China, and national security concerns have made it hard for American companies to partner with Chinese battery makers to build factories in the United States...

Although American scientists invented LFP batteries in 1997, U.S. automakers didn't invest in the technology. Instead, they bet on NMC batteries because they have longer range, a big concern for American EV buyers. "Everyone in the West thought LFP was a nonstarter five or six years ago," said Adrian Yao, who founded STEER, a technology research group within Stanford University. "We really did have a myopic focus on" range, he added. That left the door open for Chinese companies to perfect LFP batteries, which have a few advantages. Instead of pricey nickel and cobalt, they use iron, which makes them 20 percent cheaper than NMC batteries, according to the International Energy Agency. While NMC batteries can be recharged up to about 1,000 times before they go kaput — which is enough to put 200,000 miles on most EVs — LFP batteries can last two or three times as long, according to Moura. Plus, LFP batteries' chemistry makes them less likely to catch fire and easier to extinguish. An NMC battery, on the other hand, is so flammable that "you could put it underwater or in space, and it'll keep burning because the oxygen it needs to keep the flame going is embedded within itself," Moura said.

That safety advantage is key, because Chinese firms figured out they could pack LFP cells closer together inside a battery pack without risking a fire. That meant they could cram more energy into LFP batteries and nearly catch up to the range of NMC batteries. Last year, the Chinese battery giant CATL made the first LFP battery with more than 600 miles of range. Since LFP batteries are made from common materials and last longer, they also have a smaller environmental footprint than NMC batteries.
Ford used LFP batteries in its Mach-E sedan (2023) and F-150 Lightning pickup trucks (2024), according to the article, "while Rivian began using them in the basic trims of its R1S SUV and R1T pickup truck this year... American LFP factories are slated to open this year in St. Louis and next year in Arizona." And an environmental engineering professor at the University of California at Berkeley predicts LFP battery factories in the U.S. will "grow quite rapidly over the next five to 10 years."

Five days ago on Patch Tuesday, Microsoft released patch KB5051987 for Windows 11 version 24H2, writes the XDA Developers site.

But "As reported by Windows Latest and various communities like Reddit and Microsoft's help forum, many users have encountered a major issue..."

Some have reported that, in addition to File Explorer failing to launch, they're unable to open folders from the desktop, save Office files, or even download files. Clicking on a folder icon may display its subfolders, but the contents within remain inaccessible... Some users on Microsoft's help forum and Reddit have also reported that the KB5051987 patch fails to install entirely. The update gets stuck at a certain percentage for hours before eventually displaying an error code. While these are among the most widely reported issues, others have surfaced as well, including problems with Taskbar preview animations, the camera, and more.
"Microsoft keeps running into brick walls with the 2024 version of Windows 11," writes ZDNet. "Each new update designed to fix the outstanding bugs ends up introducing other problems..." Among the glitches resolved were ones that affected digital audio converters, USB audio drivers, USB cameras, and passkeys. The update also patched several security vulnerabilities, including some that were deemed critical....

Other glitches that may pop up include a stuttering mouse, an undetectable camera, .NET apps that cannot be installed inside the Windows Sandbox, and the Taskbar's new preview animation that does not work properly. You may also encounter other roadblocks. One person in the Windows Feedback Hub said that after installing the update, the battery life shows only 2.5 hours versus 6 hours previously. Another person found that the clipboard history no longer copies items from Microsoft Word...

Each annual Windows update can suffer from bugs, especially after being rolled out to millions of users. However, Windows 11 24H2 has been more problematic than usual. Since its official launch last October, the 2024 version has carried with it a host of known issues, many of which still haven't been resolved.

"IBM stopped supporting OS/2 at the end of 2006," write the makers of ArcaOS, an OEM distribution of OS/2's discontinued Warp operating system.

And now long-time Slashdot reader martiniturbide tells us that ArcaOS 5.1.1 has been released, and that many of it's components have been updated too. From this week's announcement: ArcaOS 5.1.1 continues to support installation on the latest generation of UEFI-based systems, as well as the ability to install to GPT-based disk layouts. This enables ArcaOS 5.1.1 to install on a wide array of modern hardware. Of course, ArcaOS 5.1.1 is just as much at home on traditional BIOS-based systems, offering enhanced stability and performance across both environments....

Need more convincing? How about a commercial operating system which doesn't spy on you, does not report your online activity to anyone, and gives you complete freedom to choose the applications you want to use, however you want to use them? How about an operating system which isn't tied to any specific hardware manufacturer, allowing you to choose the platform which is right for you, and fits perfectly well in systems with less than 4GB of memory or even virtual machines?

The U.S. Space Force released the first-ever public image of its secretive X-37B space plane in orbit, captured during its ongoing seventh mission that launched on December 28, 2023. Space.com reports: The photo, released on Thursday (Feb. 20), was taken by a camera onboard the X-37B while the secretive space plane orbited high above the African continent. One of the plane's solar panels is visible on the left side of the photo, while what appears to be its open payload bay is visible along the top edge. The vehicle has been in orbit for well over a year now, having launched on its seventh mission on Dec. 28, 2023 atop a SpaceX Falcon Heavy rocket.

And now, the X-37B has notched another milestone with the Space Force's release of this photo, the first-ever image of this space plane in orbit that has been shown to the public. While the photo contains scant details about the vehicle and what it's currently testing, it offers a look at Earth far in the background, revealing just how high the vehicle is flying on its seventh mission. We've gotten only one other glimpse at the X-37B in orbit prior to this. During the livestream of its most recent launch, a brief shot of the spacecraft deploying from Falcon Heavy's upper stage was seen while its service module was still attached.

An anonymous reader quotes a report from TechCrunch: A study by the Pew Research Center found that Americans' views of Elon Musk and Mark Zuckerberg skew more negative than positive. While Zuckerberg has sparked chatter in Silicon Valley with his sudden interest in high fashion, the Meta CEO is less popular than President Trump's right-hand man, Elon Musk, the report found. While about 54% of U.S. adults say they have an unfavorable view of Musk, 67% feel negatively toward Zuckerberg. [...] But Zuckerberg, the Facebook founder, is more universally disliked, though he draws more ire from the left-leaning demographic. While 60% of Republican and Republican-leaning respondents hold an unfavorable view of Zuckerberg, 76% of their Democratic counterparts share that sentiment.

So, while Zuck may be playing the part of the cool guy, Americans haven't been fooled by his gold chains or musical ambitions, it seems. Pew's study involved a panel of 5,086 randomly selected U.S. adults. The survey was conducted from January 27, 2025, through February 2, 2025, so these responses reflect people's recent opinions.

OpenAI has banned a group of Chinese accounts using ChatGPT to develop an AI-powered social media surveillance tool. Engadget reports: The campaign, which OpenAI calls Peer Review, saw the group prompt ChatGPT to generate sales pitches for a program those documents suggest was designed to monitor anti-Chinese sentiment on X, Facebook, YouTube, Instagram and other platforms. The operation appears to have been particularly interested in spotting calls for protests against human rights violations in China, with the intent of sharing those insights with the country's authorities.

"This network consisted of ChatGPT accounts that operated in a time pattern consistent with mainland Chinese business hours, prompted our models in Chinese, and used our tools with a volume and variety consistent with manual prompting, rather than automation," said OpenAI. "The operators used our models to proofread claims that their insights had been sent to Chinese embassies abroad, and to intelligence agents monitoring protests in countries including the United States, Germany and the United Kingdom."

According to Ben Nimmo, a principal investigator with OpenAI, this was the first time the company had uncovered an AI tool of this kind. "Threat actors sometimes give us a glimpse of what they are doing in other parts of the internet because of the way they use our AI models," Nimmo told The New York Times. Much of the code for the surveillance tool appears to have been based on an open-source version of one of Meta's Llama models. The group also appears to have used ChatGPT to generate an end-of-year performance review where it claims to have written phishing emails on behalf of clients in China.

Software engineering job listings have plummeted to a five-year low, with postings on Indeed dropping to 65% of January 2020 levels -- a steeper decline than any other tech-adjacent field. According to data from Indeed's job aggregator, software development positions are now at 3.5x fewer vacancies compared to their mid-2022 peak and 8% lower than a year ago.

The decline appears driven by multiple factors including widespread adoption of AI coding tools -- with 75% of engineers reporting use of AI assistance -- and a broader tech industry recalibration after aggressive pandemic-era hiring. Notable tech companies like Salesforce are maintaining flat engineering headcount while reporting 30% productivity gains from AI tools, according to an analysis by software engineer Gergely Orosz.

While the overall job market shows 10% growth since 2020, software development joins other tech-focused sectors in decline: marketing (-19%), hospitality (-18%), and banking/finance (-7%). Traditional sectors like construction (+25%), accounting (+24%), and electrical engineering (+20%) have grown significantly in the same period, he wrote. The trend extends beyond U.S. borders, with Canada showing nearly identical patterns. European markets and Australia demonstrate more resilience, though still below peak levels.

Rivian reported its first-ever positive gross profit of $170 million in Q4 2024, driven by cost reductions and increased regulatory credit sales, despite a $4.7 billion net loss for the year. The company said it expects to sell 46,000-51,000 vehicles this year and achieve "modest gross profit." The Verge reports: Rivian reported $170 million in positive gross profits, which includes production and sales but does not factor in other expenses, for the three-month period that ended December 31, 2024. That was based on $1.7 billion in revenues. The company said its net loss for the fourth quarter was $743 million, as compared to $1.5 billion in net losses in the same period in 2023.

Rivian earned $4.5 billion in revenue for the full year 2024, based on the delivery of 51,579 vehicles. It record a net loss of $4.7 billion, compared to $5.4 billion in 2023. Rivian cited increased revenue from the sale of regulatory credits to other automakers, which is also a primary revenue driver for Tesla. The company said it saw a $260 million increase in regulatory credit sales in the fourth quarter year over year.

The Canadian government has launched a six-year, $3.9 billion design phase for a high-speed rail project connecting Toronto and Quebec City, with electric trains reaching up to 300 km/h. Construction is expected to begin after the design phase, potentially in four to five years, but future governments could modify or cancel the project. CBC News reports: "Today I'm announcing the launch of Alto, the largest infrastructure project in Canadian history," Trudeau said from Montreal. "A reliable, efficient, high-speed rail network will be a game-changer for Canadians." Trudeau said the new rail network will run all-electric trains along 1,000 kilometers of track, reaching speeds of up to 300 km/hour, with stops in Toronto, Peterborough, Ottawa, Montreal, Laval, Trois-Rivieres and Quebec City. A government statement said the project will stimulate the economy, "boosting GDP by up to $35 billion annually, creating over 51,000 good-paying jobs during construction."

Trudeau said that once built, the new high-speed rail network will take passengers from Montreal to Toronto in three hours -- about half the time it takes to drive and at double the speed of Via Rail's current trains. [...] Trudeau said the consortium Cadence -- made up of CDPQ Infra, Atkins Realis, Keolis, SYSTRA, SNCF Voyageurs and Air Canada -- was selected to build the line. The group was only informed in the last 24 hours that their bid was the best of the three submitted, according to sources that spoke to Radio-Canada. Transport Minister Anita Anand said that Alto, the Crown corporation created to oversee the project, and Cadence will be signing a contract "in the coming weeks" that will outline the first-phase design work, such as where track will be laid and where stations will be built.

"[O]ur intrepid China reporter, Caiwei Chen, has identified a new trend unfolding within China's tech scene: Companies that were dominant in electric vehicles are betting big on translating that success into developing humanoid robots," writes MIT Technology Review's James O'Donnell. "I spoke with her about what she found out and what it might mean for Trump's policies and the rest of the globe..." An anonymous reader quotes an excerpt from the report: Your story looks at electric-vehicle makers in China that are starting to work on humanoid robots, but I want to ask about a crazy stat. In China, 53% of vehicles sold are either electric or hybrid, compared with 8% in the US. What explains that?

Price is a huge factor -- there are countless EV brands competing at different price points, making them both affordable and high-quality. Government incentives also play a big role. In Beijing, for example, trading in an old car for an EV gets you 10,000 RMB (about $1,500), and that subsidy was recently doubled. Plus, finding public charging and battery-swapping infrastructure is much less of a hassle than in the US.

You open your story noting that China's recent New Year Gala, watched by billions of people, featured a cast of humanoid robots, dancing and twirling handkerchiefs. We've covered how sometimes humanoid videos can be misleading. What did you think?

I would say I was relatively impressed -- the robots showed good agility and synchronization with the music, though their movements were simpler than human dancers'. The one trick that is supposed to impress the most is the part where they twirl the handkerchief with one finger, toss it into the air, and then catch it perfectly. This is the signature of the Yangko dance, and having performed it once as a child, I can attest to how difficult the trick is even for a human! There was some skepticism on the Chinese internet about how this was achieved and whether they used additional reinforcement like a magnet or a string to secure the handkerchief, and after watching the clip too many times, I tend to agree.

President Trump has already imposed tariffs on China and is planning even more. What could the implications be for China's humanoid sector?

Unitree's H1 and G1 models are already available for purchase and were showcased at CES this year. Large-scale US deployment isn't happening yet, but China's lower production costs make these robots highly competitive. Given that 65% of the humanoid supply chain is in China, I wouldn't be surprised if robotics becomes the next target in the US-China tech war.

In the US, humanoid robots are getting lots of investment, but there are plenty of skeptics who say they're too clunky, finicky, and expensive to serve much use in factory settings. Are attitudes different in China?

Skepticism exists in China too, but I think there's more confidence in deployment, especially in factories. With an aging population and a labor shortage on the horizon, there's also growing interest in medical and caregiving applications for humanoid robots.

DeepSeek revived the conversation about chips and the way the US seeks to control where the best chips end up. How do the chip wars affect humanoid-robot development in China?

Training humanoid robots currently doesn't demand as much computing power as training large language models, since there isn't enough physical movement data to feed into models at scale. But as robots improve, they'll need high-performance chips, and US sanctions will be a limiting factor. Chinese chipmakers are trying to catch up, but it's a challenge.

Murena has launched the Murena Pixel Tablet, a de-Googled version of the Pixel Tablet that removes Google's apps and services to enhance user privacy. Priced at $549, it offers /e/OS, an alternative app store, and privacy-focused productivity tools, but lacks Google's speaker dock and direct access to the Play Store. The Verge reports: First announced last December, the Murena Pixel Tablet is available now through the company's online store for $549. That's a steep premium given Google currently sells the same 128GB version of the Pixel Tablet for $399, or $479 as part of a bundle with the charging speaker dock that Murena isn't including. Part of Murena's de-Googling of the Pixel Tablet includes the removal of the Google Play Store. You can still download apps through /e/OS' App Lounge which acts as a front-end for the Play Store allowing you to browse and get free apps anonymously without Google knowing who you are. However, downloading paid apps requires a login to a Google account. Google's various productivity apps aren't included, but the Murena Pixel Tablet comes with privacy-minded alternatives for messaging, email, maps, browsing the web, calendar, contacts, notes, and even voice recordings. In 2022, Murena launched its first smartphone with no Google apps, Google Play Services, or even the Google Assistant.

Nikola, the hydrogen-truck maker that briefly sported a market value comparable to Ford Motor, has filed for bankruptcy with plans to wind down its business. From a report: Nikola on Wednesday said that it made the chapter 11 filing with the U.S. Bankruptcy Court in Delaware and that it plans to conduct a court-supervised auction of its assets.

The Phoenix company said it worked for months with its financial and legal advisers to find a way to sustain its operations before determining that a structured sale process was the best way to maximize the value of its assets.

After two decades of quantum computing research, Microsoft has unveiled its first quantum chip: the Majorana 1. CNBC reports: Microsoft's quantum chip employs eight topological qubits using indium arsenide, which is a semiconductor, and aluminum, which is a superconductor. A new paper in the journal Nature describes the chip in detail. Microsoft won't be allowing clients to use its Majorana 1 chip through the company's Azure public cloud, as it plans to do with its custom artificial intelligence chip, Maia 100. Instead, Majorana 1 is a step toward a goal of a million qubits on a chip, following extensive physics research.

Rather than rely on Taiwan Semiconductor or another company for fabrication, Microsoft is manufacturing the components of Majorana 1 itself in the U.S. That's possible because the work is unfolding at a small scale. "We want to get to a few hundred qubits before we start talking about commercial reliability," Jason Zander, a Microsoft executive vice president, told CNBC. In the meantime, the company will engage with national laboratories and universities on research using Majorana 1.

Google has built an AI laboratory assistant to help scientists accelerate biomedical research [non-paywalled source], as companies race to create specialised applications from the cutting-edge technology. From a report: The US tech group's so-called co-scientist tool helps researchers identify gaps in their knowledge and propose new ideas that could speed up scientific discovery. "What we're trying to do with our project is see whether technology like the AI co-scientist can give these researchers superpowers," said Alan Karthikesalingam, a senior staff clinician scientist at Google.

[...] Early tests of Google's new tool with experts from Stanford University, Imperial College London and Houston Methodist hospital found it was able to generate scientific hypotheses that showed promising results. The tool was able to reach the same conclusions -- for a novel gene transfer mechanism that helps scientists understand the spread of antimicrobial resistance -- as a new breakthrough from researchers at Imperial. Imperial's results were not in the public domain as they were being peer-reviewed in a top scientific journal. This showed that Google's co-scientist tool was able to reach the same hypothesis using AI reasoning in a matter of just days, compared with the years the university team spent researching the problem.

Microsoft is reminding IT administrators that WSUS driver synchronization will be deprecated on April 18, 2025, urging them to transition to cloud-based update solutions like Windows Autopatch, Azure Update Manager, and Microsoft Intune. "For on-premises contexts, drivers will be available on the Microsoft Update catalog, but you won't be able to import them into WSUS," the company said in a Windows message center update on Tuesday. "You'll need to use any of the available alternative solutions, such as Device Driver Packages, or transition to cloud-based driver services for your organization, such as Microsoft Intune and Windows Autopatch." BleepingComputer reports: This reminder follows two other warnings issued since June 2024, announcing the deprecation of WSUS driver synchronization and encouraging customers to adopt Redmond's newer cloud-based driver services. The company also revealed in September 2024 that WSUS had been deprecated, but Microsoft added that it plans to keep publishing updates through the channel and maintain all existing capabilities. This announcement came after WSUS was listed on August 13 as one of the "features removed or no longer developed starting with Windows Server 2025."

"Specifically, this means that we are no longer investing in new capabilities, nor are we accepting new feature requests for WSUS," Microsoft's Nir Froimovici said at the time. "However, we are preserving current functionality and will continue to publish updates through the WSUS channel. We will also support any content already published through the WSUS channel."

Nvidia has confirmed on its forums that the RTX 50 series GPUs no longer support 32-bit PhysX. Tom's Hardware reports: As far as we know, there are no 64-bit games with integrated PhysX technology, thus terminating the tech entirely on RTX 50 series GPUs and newer. RTX 40 series and older will still be able to run 32-bit CUDA applications and thus PhysX, but regardless, the technology is now officially retired, starting with Blackwell. [...]

The only way now to run PhysX on RTX 50 series GPUs (or newer) is to install a secondary RTX 40 series or older graphics card and slave it to PhysX duty in the Nvidia control panel. As far as we are aware, Nvidia has not disabled this sort of functionality. But the writing is on the wall for PhysX, and we doubt there will be any future games that attempt to use the API.

Meta's WhatsApp messaging service has surpassed 45 million users, earning the designation of a "Very Large Online Platform" under the EU's Digital Services Act. Bloomberg reports: WhatsApp's open channels, which are feeds affiliated with news outlets or public figures that under the DSA are comparable to a social network, averaged about 46.8 million monthly average users in the second half of 2024, Meta said in a filing on Feb. 14 that hasn't previously been reported. [...] The DSA content moderation rulebook imposes stricter requirements on very large online platforms, defined as those whose EU-based monthly active users exceed 45 million. Users of WhatsApp's core messaging feature do not count toward the designation under the DSA.

The commission would still need to rule that WhatsApp should be included in the more regulated tier. Under the DSA, very large online platforms must carry out risk assessments on the spread of illegal or harmful content, and put in place a mitigation strategy. Fines under the DSA can reach as much as 6% of a company's annual global sales. The DSA requires platforms to disclose user numbers every six months. Messaging service Telegram also published an update this week, saying that monthly EU users of its public channels are "significantly fewer than 45 million."

Google has gained permission to sell its e-books and audiobooks directly to customers through its iOS app, Google Play Books. From a report: While iOS apps today can offer access to content previously purchased elsewhere, like e-books bought via a website, developers have to request a specific exception to link their iOS app's users to the company's own website to make purchases. According to a brief post on Google's blog, users will now be able to click on a new "Get book" button in the Google Play Books iOS app which will take them to the Google Play website to complete their e-book or audiobook purchase.

From there, users will be able to see their recently opened book listings and complete a purchase using their Google Account and saved payment information. By processing the transaction on its own website, Google can avoid paying Apple a commission (generally 30%) on in-app purchases of digital content.

An anonymous reader quotes a report from Gizmodo: Protector, an app that lets you book armed goons the same way you'd call for an Uber, is having a viral moment. The app started doing the rounds on social media after consultant Nikita Bier posted about it on X. Protector lets the user book armed guards on demand. Right now it's only available in NYC and LA. According to its marketing, every guard is either "active duty or retired law enforcement and military." Every booking comes with a motorcade and users get to select the number of Escalades that'll be joining them as well as the uniforms their hired goons will wear.

Protector is currently "#7 in Travel" on Apple's App Store. It's not available for people who use Android devices. [...] The marketing for Protector, which lives on its X account, is surreal. A series of robust and barrel-chested men in ill-fitting black suits deliver their credentials to the camera while sitting in front of a black background. They're all operators. They describe careers in SWAT teams and being deployed to war zones. They show vanity shots of themselves kitted out in operator gear. All of them have a red lapel pin bearing the symbol of Protector. If the late UnitedHealthcare CEO had used Protector, he might still be alive today, suggests Protector in its marketing materials. A video on X shows "several fantasy versions of the assassination where a Protector is on hand to prevent the assassin from killing the CEO," reports Gizmodo.

The app is a product from parent company Protector Security Solutions, which was founded by Nick Sarath, a former product designer at Meta.

An anonymous reader shares a report: Later this month, Intuitive Machines, the private company behind the first commercial lander that touched down on the moon, will launch a second lunar mission from NASA's Kennedy Space Center. The plan is to deploy a lander, a rover, and hopper to explore a site near the lunar south pole that could harbor water ice, and to put a communications satellite on lunar orbit. But the mission will also bring something that's never been installed on the moon or anywhere else in space before -- a fully functional 4G cellular network.

Point-to-point radio communications, which need a clear line of sight between transmitting and receiving antennas, have always been a backbone of both surface communications and the link back to Earth, starting with the Apollo program. Using point-to-point radio in space wasn't much of an issue in the past because there never have been that many points to connect. Usually, it was just a single spacecraft, a lander, or a rover talking to Earth. And they didn't need to send much data either. "They were based on [ultra high frequency] or [very high frequency] technologies connecting a small number of devices with relatively low data throughput," says Thierry Klein, president of Nokia Bell Labs Solutions Research, which was contracted by NASA to design a cellular network for the moon back in 2020.
