  • The UK Will Invest Billions to Build a Nuclear Fusion Industry
    by EditorDavid on 16/03/2026 at 1:34 am

    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. Read more of this story at Slashdot.

  • 2026's EV Sales Hit 1.1M - But Europe Surges While North America Slides
    by EditorDavid on 15/03/2026 at 10:51 pm

    Europe's EV sales for January and February spiked 21% from last year, according to new data from Benchmark Mineral Intelligence. Electrek reports that just in those two months over 600,000 EVs were sold in Europe. And figures for "rest of world" (which excludes Europe, North America, and China) are up a whopping 84% — with 370,000 EVs sold in January and February. (EVs now represent more than 30% of the vehicles sold in South Korea.) But for the same period China's sales are down 26% from last year, with 1.1 million vehicles sold. And North America showed an even larger drop of 36% from the January/February figures in 2025, now selling just 170,000 electric vehicles, while Canada's EV sales were down 23%. EV sales seem heavily influenced by government incentives, with Germany and France leading Europe's growth: EV sales in Germany are up 26% so far this year, following the country's introduction of a new subsidy program at the start of 2026. France's market is up 30%, supported by its existing incentive program. Italy is also seeing rapid growth. EV sales there jumped 23% month-over-month in February, making it the country's strongest month ever for EV sales. The Italian market is now up 98% year to date. That surge follows the Italian government's October 2025 launch of a new subsidy program, funded by the EU's Recovery and Resilience Facility, to increase EV adoption. Households can receive up to €11,000 ($12,700) in incentives, while smaller businesses can get up to €20,000 ($23,200)... [T]he global EV transition isn't slowing, but it's becoming much more uneven depending on policy, incentives, and trade rules. Read more of this story at Slashdot.

  • Ask Slashdot: What's the Best All-Purpose RISC-V System on a Chip Family?
    by EditorDavid on 15/03/2026 at 9:51 pm

    Slashdot reader SysEngineer does embedded/IoT work, but "I want to pick a single system-on-a-chip architecture family and commit to it across multiple product lines — sensor nodes up through edge gateways... I've been on one platform for years and want to know what embedded engineers are actually running in production before I commit!" And "the family needs to scale — cheap and small at the low end, capable of running Linux on the bigger variants!" Their requirements? WiFi + BLE required LoRaWAN a nice-to-have. Low power modes that actually work in the field, not just on the datasheet. Full peripheral set — SPI, I2C, UART, ADC, timers, CAN. A toolchain and runtime support, support multi threads... Slashdot reader Gravis Zero is skeptical all the requirements can be met. "If you want embedded, you get embedded. If you want to run a big OS, you get one that will run a big OS." But Slashdot reader SysEngineer believes "The obvious architecture candidates are ARM, STM, and RISC-V" — and specifically they want to hear your experiences with the RISC-V choices. "What would you standardize on today if you were starting fresh? And how does real-world toolchain and community support hold up compared to the marketing?" Share your own thoughts and experiences in the comments. What's the best all-purpose RISC-V system on a chip family? Read more of this story at Slashdot.

  • CachyOS Dethrones Arch As ProtonDB's Top Linux Gamer Desktop Distro
    by EditorDavid on 15/03/2026 at 8:51 pm

    Linux gaming "has gotten to the point where some people claim that Linux runs their games better than Windows does," according to the Android site XDA Developers. And there's a new surprise on ProtonDB, an "unofficial" community website with crowdsourced data about videogame compatability with the Linux software/gaming compatability layer Proton: On ProtonDB, one operating system had reigned supreme since 2021: Arch Linux. And I say 'had,' because its streak has just been ended by [Arch-based] CachyOS in an upset that has slowly grown over the past two years. As reported on Boiling Steam, the number of reports coming from CachyOS has topped that of Arch Linux, which held the crown for the most number of reports since 2021... [T]his isn't really a statement that CachyOS is the best gaming distro out there; however, it's seemingly attracting the largest number of gamers who are invested in testing games on Proton and reporting their performance, which is a pretty big milestone if you ask me.

  • How One Company Finally Exposed North Korea's Massive Remote Workers Scam
    by EditorDavid on 15/03/2026 at 7:49 pm

    NBC News investigates North Korea's "wide-ranging effort to place remote workers at U.S. companies in order to funnel money back to its coffers and, in some cases, steal sensitive information." And working with the FBI, one corporate security/investigations company decided to knowingly hire one of North Korea's remote workers — then "ship him a laptop and gain as much information as possible" about this "sprawling international employment scheme that is estimated to include hundreds of American companies, thousands of people and hundreds of millions of dollars per year." It worked.... Over a roughly three-month investigation, Nisos uncovered an apparent network of at least 20 North Korean operatives including "Jo" who had collectively applied to at least 160,000 roles. During that time, workers in the network — which some evidence showed were based in China — were employed by five U.S.-based companies and allegedly helped by an American citizen operating out of two nondescript suburban homes in Florida... Nisos estimated that in about a year, "Jo", who was likely a newer member of the team, applied to about 5,000 jobs... "They attended interviews all day every day, and then once they secured a job, they would collect paychecks until they were terminated," [according to Jared Hudson, Nisos' chief technology officer]... With the ability to see which other U.S. companies Jo and his team were working for — all remote technology roles — Nisos' CEO, Ryan LaSalle, began making calls to their security teams to alert them of the fraud. "Most of the companies weren't aware of it, even if they had pretty robust security teams," LaSalle said. "It wasn't really high on the radar." NBC News describes North Korea's 10-year effort — and its educational pipeline that steers promising students into "computer science and hacking training before being placed into cyberunits under military and state agencies, according to a recent report by DTEX, a risk-adaptive security and behavioral intelligence firm that tracks North Korea's cybercrime." In one case, a North Korean worker stole sensitive information related to U.S. military technology, according to the Justice Department. In another, an American accomplice obtained an ID that enabled access to government facilities, networks and systems. At least three organizations have been extorted and suffered hundreds of thousands of dollars in damages after proprietary information was posted online by IT workers... Analysts warn that North Korean IT workers are targeting larger organizations, increasing extortion attempts and seeking out employers that pay salaries in cryptocurrency. More recently, security researchers have uncovered fake job application platforms impersonating major U.S. cryptocurrency and AI firms, including Anthropic, designed to infect legitimate applicants' networks with malware to be utilized once hired. The global cybersecurity company CrowdStrike identified a 220% rise in 2025 in instances of North Koreans gaining fraudulent employment at Western companies to work remotely as developers... The payoff flowing back to Pyongyang from these schemes is enormous. Some North Korean IT workers earn more than $300,000 per year, far more than they'd be able to earn domestically, with as much as 90% of their wages directed back to the regime, according to congressional testimony from Bruce Klinger, a former CIA deputy division chief for Korea. The United Nations estimates the schemes, which proliferated after the pandemic when more companies' workforces went remote, generate as much as $600 million annually, while a U.S. State Department-led sanctions monitoring assessment placed earnings for 2024 as high as $800 million... So far, at least 10 alleged U.S.-based facilitators have been federally charged, including one active-duty member of the U.S. Army, for their alleged roles in hosting laptop farms, laundering payments and moving proceeds through shell companies. At least six other alleged U.S. facilitators have been identified in court documents but not named... "We believe there are many more hundreds of people out there who are participating in these schemes," said Rozhavsky, the FBI assistant director. "They could never pull this off if they didn't have willing facilitators in the U.S. helping them...." The scheme itself is also becoming more complex. North Korean IT teams are now subcontracting work to developers in Pakistan, Nigeria and India, expanding into fields like customer service, financial processing, insurance and translation services — roles far less scrutinized than software development.

  • Uber Co-founder Travis Kalanick's Newest Venture? 'Gainfully Employed Robots'
    by EditorDavid on 15/03/2026 at 5:55 pm

    Uber co-founder Travis Kalanick launched a new venture that "will focus on creating 'gainfully employed robots' for the food, mining and transport industries," Bloomberg reports. "I left Uber in 2017 heartbroken," writes Kalanick on the new company's web site. Kalanick resigned under pressure in 2017, and complains he was "torn away from an idea and a movement that I had poured my life into... I bled, but I did not perish. I got back up and fought my way back into the arena, back to my calling. Back to building. Digitizing the Physical World is my life's work... " Kalanick is remaking his real estate company, City Storage Systems, which owns ghost-kitchen operator CloudKitchens, and renaming it Atoms, according to a manifesto posted on the new company's website. [Bloomberg notes that the company's food robotics division "makes a food assembly machine called Bowl Builder, according to its website."] In addition to its work on food, Los Angeles-based Atoms is expanding into robotics technology for mining and automotive transport. Kalanick said on the livestreamed tech talk show TBPN Friday that Atoms has effectively been in stealth for eight years and has "thousands" of employees.... Kalanick wrote on the Atoms website that the company will make "specialized robots with productive jobs that bring abundance to their owners and society at large." That will include "infrastructure for better food," he wrote, as well as "more productive mines to power Earth's industries" in addition to "wheelbase for robots" in transportation. "The industrial thing is probably our main jam," he said on TBPN. "Once you crack movement in the physical world, there are lots of people who want access to that..." Kalanick also said he was the biggest investor in Pronto, a self-driving trucking startup that currently focuses on closed sites like mines. Read more of this story at Slashdot.
