UK startup Pulsar Fusion says it has achieved the first plasma ignition inside a nuclear fusion rocket engine prototype -- a huge step for space travel that could cut missions to Mars "from months-long journeys to just a few weeks," reports Euronews. From the report: Pulsar Fusion revealed the milestone during a live stream at Amazon's MARS Conference, hosted by Jeff Bezos in California this week, with CEO Richard Dinan calling it an "exceptional moment" for the company. The team successfully created plasma - an intensely hot, electrically charged state of matter, often described as the fourth state of matter - using electric and magnetic fields inside its experimental and early prototype "Sunbird fusion exhaust system." [...] The company now plans further testing of its Sunbird system to improve performance. Upcoming upgrades include more powerful superconducting magnets designed to better contain and control plasma.

An anonymous reader quotes a report from Ars Technica: AOMedia Video 1 (AV1) was invented by a group of technology companies to be an open, royalty-free alternative to other video codecs, like HEVC/H.265. But a lawsuit that Dolby Laboratories Inc. filed this week against Snap Inc. calls all that into question with claims of patent infringement. Numerous lawsuits are currently open in the US regarding the use of HEVC. Relevant patent holders, such as Nokia and InterDigital, have sued numerous hardware vendors and streaming service providers in pursuit of licensing fees for the use of patented technologies deemed essential to HEVC.

It's a touch rarer to see a lawsuit filed over the implementation of AV1. The Alliance for Open Media (AOMedia), whose members include Amazon, Apple, Google, Microsoft, Mozilla, and Netflix, says it developed AV1 "under a royalty-free patent policy (Alliance for Open Media Patent License 1.0)" and that the standard is "supported by high-quality reference implementations under a simple, permissive license (BSD 3-Clause Clear License)."

Yet, Dolby's lawsuit filed in the US District Court for the District of Delaware [PDF] alleges that AV1 leverages technologies that Dolby has patented and has not agreed to license for free and without receiving royalties. The filing reads: "[AOMedia] does not own all patents practiced by implementations of the AV1 codec. Rather, the AV1 specification was developed after many foundational video coding patents had already been filed, and AV1 incorporates technologies that are also present in HEVC. Those technologies are subject to existing third-party patent rights and associated licensing obligations." Dolby is seeking a jury trial, a declaration that Dolby isn't obligated to license the patents in questions under FRAND (fair, reasonable, and non-discriminatory) licensing obligations, and for the court to enjoin Snap from further "infringement."

CERN has confirmed it will host an expanded version of Open Research Europe, the EU-backed fee-free open access publishing platform that works to "keep knowledge in public hands." Research Professional News reports: A little over a year ago, 10 European research organizations announced that they would add their support to Open Research Europe, to broaden eligibility beyond only those researchers funded by the EU research program. Earlier this year, RPN reported that this group had expanded further and that Cern was set to host the broadened version of ORE, currently provided by the publisher F1000.

On March 26, Cern itself finally announced the news, saying it will "provide the technical and operational infrastructure" for the broader version. It said this will build on its "longstanding experience in developing and maintaining open science infrastructures and community-governed services." [...] In its own announcement, the Commission said ORE will have a budget of 17 million euros for 2026-31, with the EU providing 10 million euros.

Since it launched five years ago, ORE has published more than 1,200 articles. Cern said the platform is "expected to support a growing number of research outputs each year." Last month, experts told RPN they thought uptake of the increased eligibility will depend on how the newly participating national organizations engage with their communities. Eleven members of Science Europe, a group of major research funding and performing organizations, are part of the expansion.

BrianFagioli writes: Mozilla just teamed up with Mila, the Quebec Artificial Intelligence Institute, to push open source AI -- and it feels like a direct response to Big Tech tightening its grip on the space. Instead of relying on closed models, the goal here is to build "sovereign AI" that's more transparent, privacy-focused, and actually under the control of developers and even governments. They're starting with things like private memory for AI agents, which sounds niche but matters if you care about where your data goes. Big question is whether open source can realistically keep up with the billions being poured into proprietary AI, but at least someone's trying to give folks an alternative. "Canada has what it takes to lead on frontier AI that the world can actually trust: the research depth, the values, and the will to do it differently. The next frontier in AI isn't just capability, it is trustworthiness, and Canada is uniquely positioned to lead on both. This partnership is a concrete step in that direction. Open, trustworthy AI isn't a compromise on ambition. It's the higher bar," said Valerie Pisano, president and CEO of Mila.

Wikipedia has banned the use of generative AI to write or rewrite articles, saying it "often violates several of Wikipedia's core content policies." That said, editors may still use it for translation or light refinements as long as a human carefully checks the copy for accuracy. Engadget reports: Editors can use large language models (LLMs) to refine their own writing, but only if the copy is checked for accuracy. The policy states that this is because LLMs "can go beyond what you ask of them and change the meaning of the text such that it is not supported by the sources cited." Editors can also use LLMs to assist with language translation. However, they must be fluent enough in both languages to catch errors. Once again, the information must be checked for inaccuracies.

"My genuine hope is that this can spark a broader change. Empower communities on other platforms, and see this become a grassroots movement of users deciding whether AI should be welcome in their communities, and to what extent," Wikipedia administrator Chaotic Enby wrote. The administrator also called the policy a "pushback against enshittification and the forceful push of AI by so many companies in these last few years."

The U.S. Postal Service plans to impose its first-ever fuel surcharge on packages (source paywalled; alternative source), adding an 8% fee starting in April as it struggles with rising fuel costs and ongoing financial pressure. The surcharge will not apply to letter mail and is currently expected to remain in place until January 2027. The Wall Street Journal reports: Other parcel carriers, including FedEx and United Parcel Service, have imposed fuel surcharges, as well as a basket of other surcharges and fees, for years. Both FedEx and UPS have dramatically raised their fuel surcharges in recent weeks as the price of oil has increased amid the turmoil in the Middle East. [...] The post office has been trying to increase the volume of packages it delivers. It previously differentiated itself from commercial carriers by saying that it doesn't apply residential, Saturday delivery or fuel or remote-delivery surcharges.

New submitter haroldbasset writes: Canada's Immigration Department rejected an applicant because the duties of her current job did not match the Canadian work experience she had claimed, but the Department's AI assistant had invented that work experience. She has been working in Canada as a health scientist -- she has a Ph.D. in the immunology of aging -- but the AI genius instead described her as "wiring and assembling control circuits, building control and robot panels, programming and troubleshooting." "It's believed to be the first time that the department explicitly referred to the use of generative AI to support application processing in immigration refusals," reports the Toronto Star. "The disclaimer also noted that all generated content was verified by an officer and that generative AI was not used to make or recommend a decision."

The applicant's lawyer was shocked "how any human being could make this decision." "Somehow, it hallucinated my client's job description," he said. "I would love to see what the officer saw. Something seriously went wrong here."

The applicant's refusal came just as Canada's Immigration Department released its first AI strategy, which frames artificial intelligence as a way to improve efficiency, service delivery, and program integrity. The department says it has long used digital tools like analytics and automation to flag fraud risks and triage applications, and is now also experimenting with generative AI for tasks such as research, summarizing, and analysis. In this case, however, the department insisted the decision was made by a human officer and that generative AI was not involved in the final decision.

A jury found Meta and YouTube negligent in a landmark social media addiction case, ruling that addictive design features such as infinite scroll and algorithmic recommendations harmed a young user and contributed to her mental health distress. The verdict awards $3 million in compensatory damages so far and could pave the way for more lawsuits seeking financial penalties and product changes across the social media industry. "Meta is responsible for 70 percent of that cost and YouTube for the remainder," notes The New York Times. "TikTok and Snap both settled with the plaintiff for undisclosed terms before the trial started." From the report: The bellwether case, which was brought by a now 20-year-old woman identified as K.G.M., had accused social media companies of creating products as addictive as cigarettes or digital casinos. K.G.M. sued Meta, which owns Instagram and Facebook, and Google's YouTube over features like infinite scroll and algorithmic recommendations that she claimed led to anxiety and depression.

The jury of seven women and five men will deliberate further to decide what further punitive damages the companies should pay for malice or fraud. The verdict in K.G.M.'s case -- one of thousands of lawsuits filed by teenagers, school districts and state attorneys general against Meta, YouTube, TikTok and Snap, which owns Snapchat -- was a major win for the plaintiffs. The finding validates a novel legal theory that social media sites or apps can cause personal injury. It is likely to factor into similar cases expected to go to trial this year, which could expose the internet giants to further financial damages and force changes to their products. The verdict also comes on the heels of a New Mexico jury ruling that found Meta liable for violating state law by failing to protect users of its apps from child predators.

Longtime Slashdot reader cusco writes: A private company in China has developed hypersonic missiles that cost the same as a Tesla Model X. This missile, the YKJ-1000, is being marketed for sale at a reported price of $99,000, and it's in mass production now after successful tests. That is far below what countries will spend to target and shoot down the missile if it's heading their way.

Besides the low cost, they can be launched from anywhere. The launcher looks like any one of the tens of millions of shipping containers floating around on the ocean, or sitting at ports, or riding along on trucks, or sitting on industrial lots. The launchers for these missiles are hiding in plain sight, in other words. Whatever tactical advantages great-power countries have in ballistics is going away, fast; 1,300 kilometers is 800 miles, and so the range is anything within 800 miles of wherever someone can send a shipping container. To keep the price down, the missile is reportedly using civilian-grade materials and widely available commercial parts, along with simpler manufacturing methods like die-casting. There are also broader savings from tapping mature supply chains and using China's large-scale civilian industrial base.

An anonymous reader quotes a report from Ars Technica: A new hacking group has been rampaging the Internet in a persistent campaign that spreads a self-propagating and never-before-seen backdoor -- and curiously a data wiper that targets Iranian machines. The group, tracked under the name TeamPCP, first gained visibility in December, when researchers from security firm Flare observed it unleashing a worm that targeted cloud-hosted platforms that weren't properly secured. The objective was to build a distributed proxy and scanning infrastructure and then use it to compromise servers for exfiltrating data, deploying ransomware, conducting extortion, and mining cryptocurrency. The group is notable for its skill in large-scale automation and integration of well-known attack techniques.

More recently, TeamPCP has waged a relentless campaign that uses continuously evolving malware to bring ever more systems under its control. Late last week, it compromised virtually all versions of the widely used Trivy vulnerability scanner in a supply-chain attack after gaining privileged access to the GitHub account of Aqua Security, the Trivy creator. Over the weekend, researchers said they observed TeamPCP spreading potent malware that was also worm-enabled, meaning it had the potential to spread to new machines automatically, with no interaction required of victims behind the keyboard. [...]

As the weekend progressed, CanisterWorm [as Aikido has named the malware] was updated to add an additional payload: a wiper that targets machines exclusively in Iran. When the updated worm infects machines, it checks if the machine is in the Iranian timezone or is configured for use in that country. When either condition was met, the malware no longer activated the credential stealer and instead triggered a novel wiper that TeamPCP developers named Kamikaze. Eriksen said in an email that there's no indication yet that the worm caused actual damage to Iranian machines, but that there was "clear potential for large-scale impact if it achieves active spread." It's unclear what the motive is for TeamPCP. Aikido researcher Charlie Eriksen wrote: "While there may be an ideological component, it could just as easily be a deliberate attempt to draw attention to the group. Historically, TeamPCP has appeared to be financially motivated, but there are signs that visibility is becoming a goal in itself. By going after security tools and open-source projects, including Checkmarx as of today, they are sending a clear and deliberate signal."

BrianFagioli writes: Canonical has joined the Rust Foundation as a Gold Member, signaling a deeper investment in the Rust programming language and its role in modern infrastructure. The company already maintains an up-to-date Rust toolchain for Ubuntu and has begun integrating Rust into parts of its stack, citing memory safety and reliability as key drivers. By joining at a higher tier, Canonical is not just adopting Rust but also stepping closer to its governance and long-term direction.

The move also highlights ongoing tensions in Rust's ecosystem. While Rust can reduce entire classes of bugs, it often depends heavily on external crates, which can introduce complexity and auditing challenges, especially in enterprise environments. Canonical appears aware of that tradeoff and is positioning itself to influence how the ecosystem evolves, as Rust continues to gain traction across Linux and beyond. "As the publisher of Ubuntu, we understand the critical role systems software plays in modern infrastructure, and we see Rust as one of the most important tools for building it securely and reliably. Joining the Rust Foundation at the Gold level allows us to engage more directly in language and ecosystem governance, while continuing to improve the developer experience for Rust on Ubuntu," said Jon Seager, VP Engineering at Canonical. "Of particular interest to Canonical is the security story behind the Rust package registry, crates.io, and minimizing the number of potentially unknown dependencies required to implement core concerns such as async support, HTTP handling, and cryptography -- especially in regulated environments."

An anonymous reader quotes a report from NPR: The Trump administration will pay $1 billion to a French company to walk away from two U.S. offshore wind leases as the administration ramps up its campaign against offshore wind and other renewable energy. TotalEnergies has agreed to what's essentially a refund of its leases for projects off the coasts of North Carolina and New York, and will invest the money in fossil fuel projects instead, the Department of Interior announced Monday.

The Trump administration has tried to halt offshore wind construction, but federal judges overturned those orders. Environmental groups denounced the TotalEnergies deal as an alternate way to block wind projects. President Donald Trump has gone all in on fossil fuels, which he says is the way to lower costs for families, increase reliability and help the U.S. maintain global leadership in artificial intelligence.

TotalEnergies pledged to not develop any new offshore wind projects in the United States. TotalEnergies CEO Patrick Pouyanne said in a statement that the company renounced offshore wind development in the United States in exchange for the reimbursement of the lease fees, "considering that the development of offshore wind projects is not in the country's interest." Pouyanne said the refunded lease fees will finance the construction of a liquefied natural gas plant in Texas and the development of its oil and gas activities, calling it a "more efficient use of capital" in the U.S. After it makes those investments, TotalEnergies will be reimbursed, up to the amount paid in lease purchases for offshore wind, according to the DOI.

An anonymous reader quotes a report from TechCrunch: Senators Adam Schiff (D-CA) and John Curtis (R-UT) introduced (PDF) a bill on Monday that could prevent prediction market platforms Kalshi and Polymarket from allowing users to wager money on sports events or play casino-style games. This bipartisan bill would not apply to FanDuel and DraftKings, which are subject to state-by-state gambling laws, rather than federal ones. "Sports prediction contracts are sports bets -- just with a different name. And yet, these contracts are currently offered in all fifty states in clear violation of state and federal law," Schiff said in a statement.

Prediction markets like Kalshi and Polymarket are regulated under the Commodity Futures Trading Commission (CFTC), which is why Schiff and Curtis are able to address them under federal jurisdiction, rather than leaving them to state-regulated sportsbooks. But these senators argue that there isn't much of a difference in practice between betting on sports via federally or state-regulated apps. Kalshi's Super Bowl trading volume, for instance, reached over $1 billion this year -- a 2700% increase year-over-year. "Too many young people in Utah are getting exposed to addictive sports betting and casino-style gaming contracts that belong under state control, not under federal regulators," Curtis said in a statement. The report notes that Kalshi is temporarily banned in Nevada and is facing criminal charges in Arizona. "Kalshi may brand itself as a 'prediction market,' but what it's actually doing is running an illegal gambling operation and taking bets on Arizona elections, both of which violate Arizona law," Arizona Attorney General Kris Mayes said in a statement last week.

"Google is beginning to replace news headlines in its search results with ones that are AI-generated," reports the Verge: After doing something similar in its Google Discover news feed, it's starting to mess with headlines in the traditional "10 blue links," too. We've found multiple examples where Google replaced headlines we wrote with ones we did not, sometimes changing their meaning in the process. For example, Google reduced our headline "I used the 'cheat on everything' AI tool and it didn't help me cheat on anything" to just five words: "'Cheat on everything' AI tool." It almost sounds like we're endorsing a product we do not recommend at all.

What we are seeing is a "small" and "narrow" experiment, one that's not yet approved for a fuller launch, Google spokespeople Jennifer Kutz, Mallory De Leon, and Ned Adriance tell The Verge. They would not say how "small" that experiment actually is. Over the past few months, multiple Verge staffers have seen examples of headlines that we never wrote appear in Google Search results — headlines that do not follow our editorial style, and without any indication that Google replaced the words we chose. And Google says it's tweaking how other websites show up in search, too, not just news.

The good news, for now, is that these changed headlines seem to be few and far between, and they're not yet the kind of tripe we've seen in Google Discover. (For example, Google Discover told me this week that the PlayStation Portal was getting a 1080p streaming mode, when it actually got a higher bitrate mode instead.) Compared to that and other lying Google Discover headlines like "US reverses foreign drone ban" — on a story reporting the opposite — the nonsense headlines we're seeing in Google Search are downright tame.
The article points out that Google "originally told us its AI headlines in Google Discover were an experiment too. A month later, it told us those AI headlines are now a feature..."

"Google confirmed that the test uses generative AI, but claimed that 'if we were to actually launch something based on this experiment, it would not be using a generative model and we would not be creating headlines with gen AI'..."
