  • ArXiv to Ban Researchers for a Year if They Submit AI Slop
    by BeauHD on 15/05/2026 at 5:00 pm

    ArXiv says it will ban authors for one year if they submit papers containing AI-generated slop, such as hallucinated citations, placeholder text, or chatbot meta-comments left in the manuscript. "If generative AI tools generate inappropriate language, plagiarized content, biased content, errors, mistakes, incorrect references, or misleading content, and that output is included in scientific works, it is the responsibility of the author(s)," said Thomas Dietterich, chair of the computer science section of ArXiv, on X. "We have recently clarified our penalties for this. If a submission contains incontrovertible evidence that the authors did not check the results of LLM generation, this means we can't trust anything in the paper." 404 Media reports: Examples of incontrovertible evidence, he wrote, include "hallucinated references, meta-comments from the LLM ('here is a 200 word summary; would you like me to make any changes?'; 'the data in this table is illustrative, fill it in with the real numbers from your experiments.'" "The penalty is a 1-year ban from arXiv followed by the requirement that subsequent arXiv submissions must first be accepted at a reputable peer-reviewed venue," Dietterich wrote. Dietterich told [404 Media] in an email on Friday morning that this is a one-strike rule -- meaning authors caught just once including AI slop in submissions will be banned -- but that decisions will be open to appeal. "I want to emphasize that we only apply this to cases of incontrovertible evidence," he said. "I should also add that our internal process requires first a moderator to document the problem and then for the Section Chair to confirm before imposing the penalty."

  • Congress Introduces Bill To Permanently Block Chinese Vehicles From US
    by BeauHD on 15/05/2026 at 4:00 pm

    Longtime Slashdot reader sinij shares a report from Car and Driver: A group of Michigan lawmakers has introduced a bill in Congress that would effectively place a permanent ban on Chinese connected vehicles from being sold in the United States. While an executive order signed by Joe Biden in early 2025 already imposed heavy restrictions, the new bill would codify and expand on the ban, as first reported by Autoweek and explained in a release by the House of Representatives Select Committee on China. The bill, titled the Connected Vehicle Security Act, was co-signed by John Moolenaar, a Michigan Republican, and Debbie Dingell, a Michigan Democrat. It joins a companion version of the same Connected Vehicle Security Act introduced last month to the Senate by Sen. Bernie Moreno, an Ohio Republican, and Sen. Elissa Slotkin, a Michigan Democrat. While the wording is similar to that found in former President Biden's January 2025 executive order, the new bill would codify the language into law, as well as determine rules for compliance and enforcement. Specifically, the new bill would restrict Chinese automakers from selling passenger cars in the United States if those vehicles contain any China-developed connectivity software. Officially, the bill covers the sale of vehicles from states deemed "foreign adversary countries," which include China, Russia, North Korea, and Iran. The proposed legislation arrives as Chinese automakers including Chery, Geely, and BYD (maker of the 2026 BYD Dolphin Surf, shown above), continue to rise in prominence in foreign markets around the world. "Doing the right thing for the wrong reasons," comments sinij. "Connected cars that spy on consumers are not a uniquely Chinese problem and should be addressed for all vehicles."

  • Honda Retreats To Hybrids After Failed EV Bet Triggers Record $9 Billion Loss
    by BeauHD on 15/05/2026 at 3:00 pm

    An anonymous reader quotes a report from Electrek: Honda is waving the white flag. The Japanese automaker previewed two new hybrids set to launch by 2028 after taking an over $9 billion hit over its failed EV bet, leading to its biggest loss in company history. Honda admitted it was "unable to deliver products that offer value for money better than that of new EV manufacturers, resulting in a decline in competitiveness," after suddenly announcing plans to cancel three new EVs in the US in March, warning restructuring costs could reach 2.5 trillion yen ($15.7 billion). After posting its first annual loss since it became a publicly traded company in 1957 on Thursday, Honda's CEO Toshihiro Mibe revealed the company's comeback plans. Honda is no longer planning to phase out gas-powered vehicles by 2040. Instead, Honda now aims "to achieve carbon neutrality by 2050," including a mix of EVs, hybrids, carbon-neutral fuels, and carbon-offset tech. Starting next year, Honda plans to begin introducing its next-gen hybrids, underpinned by a new hybrid system and platform. Honda said it aims to improve fuel economy by over 10% in its upcoming hybrids. The new system is expected to help cut costs by over 30% compared to Honda's current hybrid system. By the end of the decade, Honda plans to launch 15 new hybrid models globally. In North America, its most important market, the company will introduce larger hybrids in the D-segment or above. Honda previewed two of the new hybrids during the business update: the Honda Hybrid Sedan Prototype and the Acura Hybrid SUV Prototype, which the company said will go on sale within the next two years.

  • Americans Would Rather Have a Nuclear Plant In Their Backyard Than a Datacenter
    by BeauHD on 15/05/2026 at 11:00 am

    A new Gallup survey found that 71% of Americans oppose having an AI data center built near them, making the facilities even less popular than nearby nuclear plants, which 53% oppose. The Register reports: When it comes to the reasons for opposing AI campuses, half of all respondents cite the effect on resources, with excess water usage and potential power grid constraints topping the list. Concern about loss of farmland and nature was surprisingly low, with just 7 percent mentioning this, but it is possible the scores are higher in rural areas. Quality-of-life concerns such as increased traffic were put forward by nearly a quarter, while a fifth mentioned higher utility bills. Many were worried about AI specifically: that it would replace human workers, that they don't trust it, that it is moving too fast, and that the industry needs regulating. Perhaps the latter sentiment is why President Trump appears to have shifted his own position on the need for AI regulations. Conversely, those in favor of datacenters cite economic benefits, with 55 percent mentioning increased job opportunities, and 13 percent saying it is because of increased tax revenues. [...] This being America in 2026, Gallup looked at how attitudes stack up depending on political affiliation. It found that Democrats, at 56 percent, are much more likely than Republicans to be strongly opposed to a server farm in their vicinity. But 39 percent of Republicans are also strongly opposed, while another 24 percent are somewhat averse to it, and only about a third are in favor. Gallup points out the contradiction: for AI usage to expand in the US, facilities that can handle the necessary computing power will have to be built. But most Americans appear to take a "not in my backyard" attitude to new bit barns, and that attitude has grown in strength. Read more of this story at Slashdot.

  • SpaceX Unveils Sweeping Starship V3 Upgrades
    by BeauHD on 15/05/2026 at 7:00 am

    SpaceX has detailed major Starship V3 upgrades ahead of a launch targeted as early as May 19. The changes are meant to move Starship closer to its core goals: rapid reuse, Starlink deployment, orbital refueling, and eventually Moon and Mars missions. Longtime Slashdot reader schwit1 shares a report from Teslarati: Here is an explicit, broken-down list of the key changes, first starting with the changes to Super Heavy V3: - Grid Fin Redesign: Reduced from four fins to three. Each fin is now 50% larger and stronger, repositioned for better catching and lifting performance. Fins are lowered on the booster to reduce heat exposure during hot staging, with hardware moved inside the fuel tank for protection. - Integrated Hot Staging: Eliminates the old disposable interstage shield. The booster dome is now directly exposed to upper-stage engine ignition, protected by tank pressure and steel shielding. Interstage actuators retract after separation. - New Fuel Transfer System: Massive redesign of the fuel transfer tube -- roughly the size of a Falcon 9 first stage -- enables simultaneous startup of all 33 Raptors for faster, more reliable flip maneuvers. - Engine Bay/Thermal Protection: Engine shrouds removed entirely; new shielding added between engines. Propulsion and avionics are more tightly integrated. CO? fire suppression system deleted for a simpler, lighter aft section. - Propellant Loading Improvements: Switched from one quick disconnect to two separate systems for added redundancy and reduced pad complexity. Next, we have the changes to Starship V3: - Completely Redesigned Propulsion System: Clean-sheet redesign supports new Raptor startup, larger propellant volume, and an improved reaction control system while reducing trapped or leaked propellant risk. - Aft Section Simplification: Fluid and electrical systems rerouted; engine shrouds and large aft cavity deleted. - Flap Actuation Upgrade: Changed from two actuators per flap to one actuator with three motors for better redundancy, mass efficiency, and lower cost. - Faster Starlink Deployment: Upgraded PEZ dispenser enables quicker satellite release. - Long-Duration Spaceflight Capability: New systems for long orbital coasts, orbital refueling, cryogenic fluid management, vacuum-insulated header tanks, and high-voltage cryogenic recirculation. - Ship-to-Ship Docking + Refueling: Four docking drogues and dedicated propellant transfer connections added to support in-space refueling architecture. - Avionics Upgrades: 60 custom avionics units with integrated batteries, inverters, and high-voltage systems (9 MW peak power). New multi-sensor navigation for precision autonomous flight. RF sensors measure propellant in microgravity. ~50 onboard camera views and 480 Mbps Starlink connectivity for low-latency communications. "Believe it or not, there's more," writes schwit1. "Two years ago, the biggest and most powerful rocket ever flown was Starship V1. Last year, it was Starship V2. V3 is about to become the biggest and most powerful rocket ever flown -- but don't worry, the company already has plans for V4." Read more of this story at Slashdot.

  • Musk Accused of 'Selective Amnesia', Altman of Lying As OpenAI Trial Nears End
    by BeauHD on 15/05/2026 at 3:30 am

    An anonymous reader quotes a report from Reuters: A lawyer for Elon Musk hammered at the credibility of OpenAI CEO Sam Altman on Thursday, near the end of a trial over whether to hold the ChatGPT maker and its leaders responsible for allegedly transforming the nonprofit into a vehicle to enrich themselves. OpenAI's lawyers fought back, claiming the world's richest person waited too long to claim OpenAI breached its founding agreement to build safe artificial intelligence to benefit humanity, and couldn't claim he was essential to its success. "Mr. Musk may have the Midas touch in some areas, but not in AI," said William Savitt, a lawyer for OpenAI. "To succeed in AI, as it turns out, all Mr. Musk can do is come to court." The claims were made during closing arguments of a trial in the Oakland, California, federal court. [...] In his closing argument, Musk's lawyer Steven Molo told jurors that five witnesses, including Musk, former OpenAI board members and former OpenAI Chief ScientistIlya Sutskever, testified that Altman was a liar. Molo also noted that during cross-examination on Tuesday, Altman did not say yes unequivocally when asked if he was completely trustworthy and did not mislead people in business. "Sam Altman's credibility is directly at issue in this case," Molo said. "If you don't believe him, they cannot win." Molo accused OpenAI of wrongfully trying to enrich investors and insiders at the nonprofit's expense, and failing to prioritize AI's safety. He also challenged Brockman's goals for the business, citing Brockman'sstatementthat his own OpenAI stake was worth nearly $30 billion. "The arrogance, the lack of sensitivity, the failure to account for just common decency is really, really abhorrent." Musk also accused Microsoft, which invested $1 billion in OpenAI in 2019 and $10 billion in 2023, of aiding and abetting OpenAI's wrongful conduct. "Microsoft was aware of what OpenAI was doing every step of the way," Molo said. Sarah Eddy, another lawyer for the OpenAI defendants, accused Musk and his legal team in her closing argument of resorting to "sound bites and irrelevant false accusations." Eddy said by 2017, everyone associated with OpenAI -- including Musk, then still on its board -- knew it needed more money to fulfill its mission than it could raise as a nonprofit. "Mr. Musk wanted to turn OpenAI into a for-profit company that he could control," she said. "But the other founders refused to turn the keys of AGI (artificial general intelligence) over to one person, let alone Elon Musk."She also said if Musk truly believed AI should serve humanity, he would not have pushed to fold OpenAI into his electric car company Tesla, or made his rival xAI a for-profit company. Musk had a three-year statute of limitations to sue, and OpenAI's lawyers said his August 2024 lawsuit came too late because he knew several years earlier about OpenAI's growth plans. Eddy expressed disbelief that Musk claimed he did not read a four-page term sheet in 2018 discussing OpenAI's plan to seek outside investments. "One of the most sophisticated businessmen in the history of the world" wouldn't have "stuck his head in the sand," Eddy said. Savitt accused Musk of having "selective amnesia." Microsoft's lawyer Russell Cohen said in his closing statement that Microsoft wasn't involved in the key events of the case, and was "a responsible partner at every step." On Monday, the nine-person jury is expected to begin deliberating. The judge and lawyers will also return to court to discuss possible remedies if Musk wins, including how OpenAI should be restructured and what damages might be awarded. If Musk loses, there will be no remedies to consider.
