Scientists have demonstrated control over a newly theorized type of magnetism, known as altermagnetism, by manipulating nanoscale magnetic whirlpools in an ultra-thin wafer of manganese telluride. "Our experimental work has provided a bridge between theoretical concepts and real-life realization, which hopefully illuminates a path to developing altermagnetic materials for practical applications," says University of Nottingham physicist Oliver Amin, who led the research with PhD student Alfred Dal Din. From the report: Using a device that accelerates electrons to blinding speeds, a team led by researchers from the University of Nottingham showered an ultra-thin wafer of manganese telluride with X-rays of different polarizations, revealing changes on a nanometer scale reflecting magnetic activity unlike anything seen before. [...] More recently, a third configuration of particles in ferromagnetic materials was theorized. In what's referred to as altermagnetism, particles are arranged in a canceling fashion like antiferromagnetism, yet rotated just enough to allow for confined forces on a nanoscale -- not enough to pin a grocery list to your freezer, but with discrete properties that engineers are keen to manipulate into storing data or channeling energy. "Altermagnets consist of magnetic moments that point antiparallel to their neighbors," explains University of Nottingham physicist Peter Wadley. "However, each part of the crystal hosting these tiny moments is rotated with respect to its neighbors. This is like antiferromagnetism with a twist! But this subtle difference has huge ramifications." Experiments have since confirmed the existence of this in-between 'alter' magnetism. However, none had directly demonstrated it was possible to manipulate its tiny magnetic vortices in ways that might prove useful. Wadley and his colleagues demonstrated that a sheet of manganese telluride just a few nanometers thick could be distorted in ways that intentionally created distinct magnetic whirlpools on the wafer's surface. "Our experimental work has provided a bridge between theoretical concepts and real-life realization, which hopefully illuminates a path to developing altermagnetic materials for practical applications," says University of Nottingham physicist Oliver Amin. This research was published in the journal Nature.

The United States Postal Service has suspended all package shipments from China and Hong Kong following President Donald Trump's decision to eliminate the de minimis exemption, which previously allowed small packages under $800 to enter the U.S. without import duties. "The move could potentially create chaos and confusion across the online shopping industry, as well as make purchases more expensive for consumers, especially because many global manufacturers and internet sellers are located in China," reports Wired. "Shoppers are now on the hook not only for the additional 10 percent tariff, but also whatever original tax rate their products were exempted from until Tuesday." From the report: Cindy Allen, who has worked in international trade for over 30 years and is the CEO of the consulting firm Trade Force Multiplier, gave WIRED an example of how much additional cost the tariff will incur: A woman's dress made of synthetic fiber shipped from China through de minimis will now be subject to a regular 16 percent tariff, a 7.5 percent Section 301 duty specifically for goods from China, the new 10 percent tariff required by Trump, additional processing fees and customs brokerage fees, and perhaps increased brokering and handling costs due to the sudden change in rules. "Will the dress that was $5 now cost $5.50 or $15?" says Allen. "That we don't know. It depends on how those retailers react and change their business models." In the immediate term, clearing customs will become a challenge for most ecommerce companies. Their long-term concern, though, is the potential impact on profitability. The appeal of Temu and Shein and similar Chinese ecommerce companies is how affordable their products are. If that changes, the ecommerce landscape and consumer behavior in the US may change significantly as well. While the USPS has announced the suspension of accepting any parcels from China and Hong Kong, CBP hasn't elaborated on how the agency will enforce Trump's new tariffs other than saying in an announcement that it will reject de minimis exemption requests from China starting today.

An anonymous reader quotes a report from The Guardian: For all motorists, but perhaps the Ferrari-collecting rocker Rod Stewart in particular, it will be music to the ears: researchers have developed a road surface that heals when it cracks, preventing potholes without a need for human intervention. The international team devised a self-healing bitumen that mends cracks as they form by fusing the asphalt back together. In laboratory tests, pieces of the material repaired small fractures within an hour of them first appearing. "When you close the cracks you prevent potholes forming in the future and extend the lifespan of the road," said Dr Jose Norambuena-Contreras, a researcher on the project at Swansea University. "We can extend the surface lifespan by 30%." Potholes typically start from small surface cracks that form under the weight of traffic. These allow water to seep into the road surface, where it causes more damage through cycles of freezing and thawing. Bitumen, the sticky black substance used in asphalt, becomes susceptible to cracking when it hardens through oxidation. To make the self-healing bitumen, the researchers mixed in tiny porous plant spores soaked in recycled oils. When the road surface is compressed by passing traffic, it squeezes the spores, which release their oil into any nearby cracks. The oils soften the bitumen enough for it to flow and seal the cracks. Working with researchers at King's College London and Google Cloud, the scientists used machine learning, a form of artificial intelligence, to model the movement of organic molecules in bitumen and simulate the behaviour of the self-healing material to see how it responded to newly formed cracks. The material could be scaled up for use on British roads in a couple of years, the researchers believe. Google published a blog post with more information about the "self-healing" asphalt.

Apple has announced Apple Invites, a new iPhone app designed to help you manage your social life. Engadget reports: The idea behind Apple Invites is that you can create and share custom invitations for any event or occasion. You can use your own photos or backgrounds in the app as an image for the invite. Image Playground is built into Invites and you can use that to generate an images for the invitation instead. Other Apple Intelligence features such as Writing Tools are baked in as well, in case you need a hand to craft the right message for your invitation. The tech giant also said it was increasing AppleCare+ subscription prices for the iPhone, "raising the cost by 50 cents for all models in the United States," according to MacRumors. From the report: Standard AppleCare+ for the iPhone 16 models is now priced at $10.49 per month, for example, up from the prior $9.99 per month price. The 50 cent price increase applies to all available AppleCare+ plans for Apple's current iPhone lineup, and it includes both the standard plan and the Theft and Loss plan. The two-year AppleCare+ subscription prices have not changed, nor have the service fees and deductibles. The increased prices are only applicable when paying for AppleCare+ on a monthly basis. Apple has not raised the prices of AppleCare+ subscription plans for the iPad, Mac, or Apple Watch.

An anonymous reader writes: Low quality books that appear to be AI generated are making their way into public libraries via their digital catalogs, forcing librarians who are already understaffed to either sort through a functionally infinite number of books to determine what is written by humans and what is generated by AI, or to spend taxpayer dollars to provide patrons with information they don't realize is AI-generated. Public libraries primarily use two companies to manage and lend ebooks: Hoopla and OverDrive, the latter of which people may know from its borrowing app, Libby. Both companies have a variety of payment options for libraries, but generally libraries get access to the companies' catalog of books and pay for customers to be able to borrow that book, with different books having different licenses and prices. A key difference is that with OverDrive, librarians can pick and choose which books in OverDrive's catalog they want to give their customers the option of borrowing. With Hoopla, librarians have to opt into Hoopla's entire catalog, then pay for whatever their customers choose to borrow from that catalog. The only way librarians can limit what Hoopla books their customers can borrow is by setting a limit on the price of books. For example, a library can use Hoopla but make it so their customers can only borrow books that cost the library $5 per use. On one hand, Hoopla's gigantic catalog, which includes ebooks, audio books, and movies, is a selling point because it gives librarians access to more for cheaper price. On the other hand, making librarians buy into the entire catalog means that a customer looking for a book about how to diet for a healthier liver might end up borrowing Fatty Liver Diet Cookbook: 2000 Days of Simple and Flavorful Recipes for a Revitalized Liver. The book was authored by Magda Tangy, who has no online footprint, and who has an AI-generated profile picture on Amazon, where her books are also for sale. Note the earring that is only on one ear and seems slightly deformed. A spokesperson for deepfake detection company Reality Defender said that according to their platform, the headshot is 85 percent likely to be AI-generated. [...] It is impossible to say exactly how many AI-generated books are included in Hoopla's catalog, but books that appeared to be AI-generated were not hard to find for most of the search terms I tried on the platform. "This type of low quality, AI generated content, is what we at 404 Media and others have come to call AI slop," writes Emanuel Maiberg. "Librarians, whose job it is in part to curate what books their community can access, have been dealing with similar problems in the publishing industry for years, and have a different name for it: vendor slurry." "None of the librarians I talked to suggested the AI-generated content needed to be banned from Hoopla and libraries only because it is AI-generated. It might have its place, but it needs to be clearly labeled, and more importantly, provide borrowers with quality information." Sarah Lamdan, deputy director of the American Library Association, told 404 Media: "Platforms like Hoopla should offer libraries the option to select or omit materials, including AI materials, in their collections. AI books should be well-identified in library catalogs, so it is clear to readers that the books were not written by human authors. If library visitors choose to read AI eBooks, they should do so with the knowledge that the books are AI-generated."

The DeepComputing RISC-V Mainboard that Framework announced last year for its 13-inch laptops is now available for $199. Liliputing reports: If you already have a Framework Laptop 13 with an Intel or AMD motherboard, the new board is a drop-in replacement. But if you don't have a Framework Laptop you can also use the mainboard as a standalone computer: Framework sells a $39 Cooler Master case that effectively turns its mainboards into mini desktop computers. The RISC-V Mainboard comes from a partnership between Framework and DeepComputing, the Chinese company behind the DC-ROMA laptops, which were some of the first notebook computers to ship with RISC-V processors. The board features a StarFive JH7110 processor, which is a 1.5 GHz quad-core chip featuring SiFive U74 RISC-V CPU cores and Imagination BXE-4-32 graphics, 8GB of onboard RAM, and a a 64GB SD card for storage (there's also support for an optional eMMC module, but you'll need to bring your own). Since the board is designed to fit in existing laptop frames, it's the same size and shape as AMD or Intel models and has four USB ports in the same locations. But these ports are a little less versatile than the ones you might find on other Framework Laptop 13 Mainboards [...]. There's also a 3.5mm audio jack. You can check out the new board via the Framework Marketplace. Further reading: Late last year, Framework CEO Nirav Patel delivered one of the best live demos we've ever seen at a tech conference -- modifying a Framework Laptop from x86 to RISC-V live on stage.

An anonymous reader quotes a report from Ars Technica: US Senator Ted Cruz (R-Texas) has been demanding an overhaul of a $42.45 billion broadband deployment program, and now his telecom policy director has been chosen to lead the federal agency in charge of the grant money. "Congratulations to my Telecom Policy Director, Arielle Roth, for being nominated to lead NTIA," Cruz wrote last night, referring to President Trump's pick to lead the National Telecommunications and Information Administration. Roth's nomination is pending Senate approval. Roth works for the Senate Commerce Committee, which is chaired by Cruz. "Arielle led my legislative and oversight efforts on communications and broadband policy with integrity, creativity, and dedication," Cruz wrote. Shortly after Trump's election win, Cruz called for an overhaul of the Broadband Equity, Access, and Deployment (BEAD) program, which was created by Congress in November 2021 and is being implemented by the NTIA. Biden-era leaders of the NTIA developed rules for the program and approved initial funding plans submitted by every state and territory, but a major change in approach could delay the distribution of funds. Cruz previously accused the NTIA of "technology bias" because the agency prioritized fiber over other types of technology. He said Congress would review BEAD for "imposition of statutorily-prohibited rate regulation; unionized workforce and DEI labor requirements; climate change assessments; excessive per-location costs; and other central planning mandates." Roth criticized the BEAD implementation at a Federalist Society event in June 2024. "Instead of prioritizing connecting all Americans who are currently unserved to broadband, the NTIA has been preoccupied with attaching all kinds of extralegal requirements on BEAD and, to be honest, a woke social agenda, loading up all kinds of burdens that deter participation in the program and drive up costs," she said. Municipal broadband networks and fiber networks in general could get less funding under the new plans. Roth is "expected to change the funding conditions that currently include priority access for government-owned networks" and "could revisit decisions like the current preference for fiber," Bloomberg reported, citing people familiar with the matter. Congress defined priority broadband projects under BEAD as those that "ensure that the network built by the project can easily scale speeds over time to meet the evolving connectivity needs of households and businesses; and support the deployment of 5G, successor wireless technologies, and other advanced services." The Biden NTIA determined that only end-to-end fiber-optic architecture meet these criteria. "End-to-end fiber networks can be updated by replacing equipment attached to the ends of the fiber-optic facilities, allowing for quick and relatively inexpensive network scaling as compared to other technologies. Moreover, new fiber deployments will facilitate the deployment and growth of 5G and other advanced wireless services, which rely extensively on fiber for essential backhaul," the Biden NTIA said (PDF).

In his post about the future of Fedora Workstation, Christian F.K. Schaller discusses how the Red Hat team plans to integrate AI with IBM's open-source Granite engine to enhance developer tools, such as IDEs, and create an AI-powered Code Assistant. He says the team is also working on streamlining AI acceleration in Toolbx and ensuring Fedora users have access to tools like RamaLama. From the post: One big item on our list for the year is looking at ways Fedora Workstation can make use of artificial intelligence. Thanks to IBMs Granite effort we know have an AI engine that is available under proper open source licensing terms and which can be extended for many different usecases. Also the IBM Granite team has an aggressive plan for releasing updated versions of Granite, incorporating new features of special interest to developers, like making Granite a great engine to power IDEs and similar tools. We been brainstorming various ideas in the team for how we can make use of AI to provide improved or new features to users of GNOME and Fedora Workstation. This includes making sure Fedora Workstation users have access to great tools like RamaLama, that we make sure setting up accelerated AI inside Toolbx is simple, that we offer a good Code Assistant based on Granite and that we come up with other cool integration points. "I'm still not sure how I feel about this approach," writes designer/developer and blogger, Bradley Taunt. "While IBM Granite is an open source model, I still don't enjoy so much artificial 'intelligence' creeping into core OS development. This also isn't something optional on the end-users side, like a desktop feature or package. This sounds like it's going to be built directly into the core system." "Red Hat has been pushing hard towards AI and my main concern is having this influence other operating system dev teams. Luckily things seems AI-free in BSD land. For now, at least."

Americans quit 39.6 million jobs in 2024, an 11% drop from 2023 and 22% below the 2022 peak, Labor Department data showed Tuesday, signaling an end to the post-pandemic job-switching frenzy. The monthly quit rate fell below pre-pandemic levels as workers faced diminishing options in a cooling labor market. Available positions per unemployed worker dropped to 1.1 from 2 in March 2022, while hiring declined to a monthly average of 3.5% in 2024 from 4.4% in 2021. Total hiring fell to 66 million in 2024 from 71 million in 2023, though the job market remained stable. The unemployment rate held at 4.1%, with economists expecting steady job growth in Friday's upcoming labor report. The Conference Board's latest survey showed fewer respondents viewing jobs as plentiful compared to the early 2020s, with more reporting difficulties finding work.

Microsoft has intensified efforts to block unsupported Windows 11 installations, removing documentation about bypassing system requirements and flagging third-party workaround tools as potential malware. The move comes as Windows 10 approaches end of support in October 2025, when users must either continue without updates, upgrade to Windows 11, or purchase new hardware compatible with Windows 11's TPM 2.0 requirement. Microsoft Defender now identifies Flyby11, a popular tool for installing Windows 11 on incompatible devices, as "PUA:Win32/Patcher." Users are also reporting that unsupported Windows 11 installations are already facing restrictions, with some machines unable to receive major updates. Microsoft has also removed text from its "Ways to install Windows 11" page that had provided instructions for bypassing TPM 2.0 requirements through registry key modifications. The removed section included technical details for users who acknowledged and accepted the risks of installing Windows 11 on unsupported hardware.

The proportion of people being diagnosed with lung cancer who have never smoked is increasing, with air pollution an "important factor," the World Health Organization's cancer agency has said. From a report: Lung cancer in people who have never smoked cigarettes or tobacco is now estimated to be the fifth highest cause of cancer deaths worldwide, according to the International Agency for Research on Cancer (IARC). Lung cancer in never-smokers is also occurring almost exclusively as adenocarcinoma, which has become the most dominant of the four main subtypes of the disease in both men and women globally, the IARC said. About 200,000 cases of adenocarcinoma were associated with exposure to air pollution in 2022, according to the IARC study published in the Lancet Respiratory Medicine journal. The largest burden of adenocarcinoma attributable to air pollution was found in east Asia, particularly China, the study found.

An anonymous reader quotes a report from Ars Technica: In what is becoming a sadly regular occurrence, two popular free software projects, X.org/Freedesktop.org and Alpine Linux, need to rally some of their millions of users so that they can continue operating. Both services have largely depended on free server resources provided by Equinix (formerly Packet.net) and its Metal division for the past few years. Equinix announced recently that it was sunsetting its bare-metal sales and services, or renting out physically distinct single computers rather than virtualized and shared hardware. As reported by the Phoronix blog, both free software organizations have until the end of April to find and fund new hosting, with some fairly demanding bandwidth and development needs. An issue ticket on Freedesktop.org's GitLab repository provides the story and the nitty-gritty needs of that project. Both the X.org foundation (home of the 40-year-old window system) and Freedesktop.org (a shared base of specifications and technology for free software desktops, including Wayland and many more) used Equinix's donated space. [...] Alpine Linux, a small, security-minded distribution used in many containers and embedded devices, also needs a new home quickly. As detailed in its blog, Alpine Linux uses about 800TB of bandwidth each month and also needs continuous integration runners (or separate job agents), as well as a development box. Alpine states it is seeking co-location space and bare-metal servers near the Netherlands, though it will consider virtual machines if bare metal is not feasible.
