  • Juicier Steaks Soon? The UK Approves Testing of Gene-Edited Cow Feed
    by EditorDavid on 21/03/2026 at 8:38 pm

    "Juicier steaks could soon be served up after barley was given the go-ahead to become Britain's first gene-edited crop," reports the Telegraph: In an effort to fatten up cows and get them to market faster, scientists have altered the DNA of Golden Promise barley to increase its fat content... [Regulators have approved the feeding of that barley to cows for further studies.] [T]he small increase reduces the time it takes for farmers to raise animals for slaughter and increases the amount of milk and meat they produce to make the industry more profitable. The gene-edited barley is also able to cut the amount of methane a cow produces, [Rothamsted Research professor/biochemist Peter] Eastmond said... Reducing methane from cattle is a major goal of the industry, and Professor Eastmond estimated his barley could cut the methane output from a single cow by up to 15%. The two genetic tweaks to the barley are believed to alter the gut bacteria in cows' stomachs and reduce the amount of methane-generating microbes, cutting the cows' emissions.... [Eastmond] is also working on applying the same two gene edits to rye grass to create pastures and meadows which are lipid-rich and calorie-dense. This, he said, could lead to entire fields of gene-edited grass which could be grazed by cows, sheep, horses and goats to fatten them up and cut emissions... "It would be better to have this technology in a pasture grass that's grown to supply the livestock and graze it directly." The barley "has been modified to have a single letter of DNA removed from two different genes to switch them off," the article points out. "No genes have been added to its DNA and it is not considered to be genetically modified." The article points out that Britain "has launched a push towards more gene-edited crops as a key post-Brexit freedom since splitting from the European Union," noting that U.K. scientists and private companies "have created products such as bread with fewer cancer-causing chemicals, longer-lasting strawberries and bananas, sweeter-tasting lettuce and disease-resistant potatoes, although these are yet to be granted permission to land on supermarket shelves..." But the EU has so far resisted the sale of any gene-edited crops in the EU. Thanks to long-time Slashdot reader fjo3 for sharing the article. Read more of this story at Slashdot.

  • Can Private Space Companies Replace the ISS Before 2030?
    by EditorDavid on 21/03/2026 at 7:34 pm

    China's orbital outpost Tiangong was completed in 2022 and is hosting up to three astronauts at a time, reports CNN. But meanwhile U.S. lawmakers are now signaling there's not time to develop and launch a replacement for the International Space Station — considered the signal most expensive object ever built — before its deorbiting in 2030. A recent Senate bill calls for the U.S. to continue funding it as late as 2032, but that bill still awaits approval from the U.S. Senate and the House. But some private space companies are already building their alternatives: Private companies that are in the early design and mockup phase of developing these space stations are still waiting on NASA for guidance — and money... [NASA's "Requests for Proposals"] were delayed, in part because it took all of 2025 to cinch a confirmation for Trump's on-again-off-again pick for NASA administrator, Jared Isaacman [confirmed in December]... Similarly, 2025 saw a 45-day government shutdown, the longest in history — adding another hiccup in the space agency's plans to begin formally soliciting proposals from the private sector. Companies now expect that NASA will issue its Request for Proposals in late March or early April, one CEO told CNN... Several commercial outfits have recently announced big funding influxes aimed at speeding up the development and launch of new orbiting outposts. Houston-based Axiom Space announced a $350 million funding round last month. Its California-based competitor Vast then notched a $500 million raise in early March. Vast is determined to launch a bare-bones station to orbit as soon as possible, with or without federal input, according to the company. "Our approach is to actually not wait for (NASA) and get going and build a minimum viable product, single-module space station called Haven-1, which we're launching into orbit next year," Vast CEO Max Haot told CNN in a phone interview earlier this month. Similarly, Axiom Space is working toward a 2028 launch date for a module that it plans to initially attach to the ISS before breaking off to orbit on its own. A spokesperson told CNN that it the company is "committed" to winning the NASA contract money and may continue pursing such goals even without contract awards. Still, there's lingering doubt that any of the companies pursuing space stations will be able to stay afloat without securing a coveted NASA contract or at least cinching significant business from the public sector. The article includes "Another complicating fact: Russia, the United States' primary partner on the ISS, has not pledged to keep operating its half of the space station past 2028." NASA will eventually evaluate proposals for an ISS alternative from Vast, Axiom Space, Jeff Bezos' Blue Origin, Max Space and several competitors including Voyager Technologies, CNN notes, ultimately handing out an estimated $1.5 billion in contracts between 2026 and 2031. And while those companies may wait decades before a return on their investment, the article includes this quotes from the cofounder/general partner of Balerion Space Ventures, which led the fundraising for Vast. " What's obvious to us is you're going to have multiple vehicles with myriad companies go into space. You're going to have vehicles leaving from celestial bodies, like the moon. And we need a habitat." Read more of this story at Slashdot.

  • Intel, NVIDIA, AMD GPU Drivers Finally Play Nice With ReactOS
    by EditorDavid on 21/03/2026 at 6:34 pm

    ReactOS aims to be compatible with programs and drivers developed for Windows Server 2003 and later versions of Microsoft Windows. And Slashdot reader jeditobe reports that the project has now "announced significant progress in achieving compatibility with proprietary graphics drivers." ReactOS now supports roughly 90% of GPU drivers for Windows XP and Windows Server 2003, thanks to a series of fixes and the implementation of the KMDF (Kernel-Mode Driver Framework) and WDDM (Windows Display Driver Model) subsystems. Prior to these changes, many proprietary drivers either failed to launch or exhibited unstable behavior. In the latest nightly builds of the 0.4.16 branch, drivers from a variety of manufacturers — including Intel, NVIDIA, and AMD — are running reliably. The project demonstrated ReactOS running on real hardware, including booting with installed drivers for graphics cards such as Intel GMA 945, NVIDIA GeForce 8800 GTS and GTX 750 Ti, and AMD Radeon HD 7530G. They also highlighted successful operation on mobile GPUs like the NVIDIA Quadro 1000M, with 2D/3D acceleration, audio, and network connectivity all functioning correctly. Further tests confirmed support on less common or older configurations, including a laptop with a Radeon Xpress 1100, as well as high-performance cards like the NVIDIA GTX Titan X. A key contribution came from a patch merged into the main branch for the memory management subsystem, which improved driver stability and reduced crashes during graphics adapter initialization.

  • 50% of Consumers Prefer Brands That Avoid GenAI Content
    by EditorDavid on 21/03/2026 at 5:34 pm

    Slashdot reader BrianFagioli writes: According to the research firm Gartner, 50% of U.S. consumers say they would prefer to do business with brands that avoid using GenAI in consumer facing content such as advertising and promotional messaging. The survey of 1,539 Americans, conducted in October 2025, also found growing skepticism about the reliability of online information, with 61% saying they frequently question whether information they use for everyday decisions is trustworthy... Gartner found that 68% of consumers often wonder whether the content they see online is real, while fewer people now rely on intuition alone to judge credibility [only 27%]. Instead, more consumers are actively verifying information and checking sources. Gartner's senior principal analyst offered suggests discretion for brands trying to use AI. "The brands that win will be the ones that use AI in ways customers can immediately recognize as helpful, while being transparent about when AI is used, what it's doing, and giving customers a clear choice to opt out."

  • Firefox Announces Built-In VPN and Other New Features - and Introduces Its New Mascot
    by EditorDavid on 21/03/2026 at 4:34 pm

    A free built-in VPN is coming to Firefox on Tuesday, Mozilla announced this week: Free VPNs can sometimes mean sketchy arrangements that end up compromising your privacy, but ours is built from our data principles and commitment to be the world's most trusted browser. It routes your browser traffic through a proxy to hide your IP address and location while you browse, giving you stronger privacy and protection online with no extra downloads. Users will have 50 gigabytes of data monthly in the U.S., France, Germany and U.K. to start. Available in Firefox 149 starting March 24. We also recently shared that Firefox is the first browser to ship Sanitizer API, a new web security standard that blocks attacks before they reach you [for untrusted HTML XSS vulnerabilities]. "The roadmap for Firefox this year is the most exciting one we've developed in quite a while," says Firefox head Ajit Varma. "We're improving the fundamentals like speed and performance. We're also launching innovative new open standards in Gecko to ensure the future of the web is open, diverse, and not controlled by a single engine. "At the same time we're prioritizing features that give users real power, choice and strong privacy protections, built in a way that only Firefox can. And as always, we'll keep listening, inviting users to help shape what comes next and giving them more reasons to love Firefox." Two new features coming next week: Split View puts two webpages side by side in one window, making it easy to compare, copy and multitask without bouncing between tabs. Rolling out in Firefox 149 on March 24. Tab Notes let you add notes to any tab, another tool to help with multitasking and picking up where you left off. Available in Firefox Labs 149 starting March 24. And Firefox also released a video this week introducing their new mascot Kit. Read more of this story at Slashdot.

  • SystemD Adds Optional 'birthDate' Field for Age Verification to JSON User Records
    by EditorDavid on 21/03/2026 at 3:34 pm

    "The systemd project merged a pull request adding a new birthDate field to the JSON user records managed by userdb in response to the age verification laws of California, Colorado, and Brazil," reports the blog It's FOSS. They note that the field "can only be set by administrators, not by users themselves" — it's the same record that already holds metadata like realName, emailAddress, and location: Lennart Poettering, the creator of systemd, has clarified that this change is "an optional field in the userdb JSON object. It's not a policy engine, not an API for apps. We just define the field, so that it's standardized iff people want to store the date there, but it's entirely optional. " In simple words, this is something that adds a new, optional field that can then be used by other open source projects like xdg-desktop-portal to build age verification compliance on top of, without systemd itself doing anything with the data or making it mandatory to provide. A merge request asking for this change to be repealed was struck down by Lennart, who gave the above-mentioned reasoning behind this, and further noted that people were misunderstanding what systemd is trying to do here. "It enforces zero policy," Poettering said. "It leaves that up for other parts of the system." Read more of this story at Slashdot.
