By some appearances, at least, the kernel community has been relatively insulated from the onslaught of AI-driven software-development tools. There has not been a flood of vibe-coded memory-management patches — yet. But kernel development is, in the end, software development, and these tools threaten to change many aspects of how software development is done. In a world where companies are actively pushing their developers to use these tools, it is not surprising that the topic is increasingly prominent in kernel circles as well. There are currently a number of ongoing discussions about how tools based on large language models (LLMs) fit into the kernel-development community.

The release of Rust 1.89 has been announced. Changes this time include support for inferring the length of certain arrays, lint messages suggesting how to clarify potentially confusing uses of lifetime elision in function signatures, and improvements to the C ABI.

President Trump on Thursday called on Intel's CEO to resign because of his past ties to China, the latest challenge for the troubled chip maker. From a report: "The CEO of INTEL is highly CONFLICTED and must resign, immediately. There is no other solution to this problem," Trump wrote in a post on Truth Social Thursday. The president appeared to be referencing Intel CEO Lip-Bu Tan's past business dealings in China, which Sen. Tom Cotton (R., Ark.) called out in a letter to the company's board earlier this week. On Tuesday, Cotton wrote an open letter to Intel's board questioning Tan's ties to the Chinese government, including apparent connections to the country's military and investments in other semiconductor companies. "The new CEO of @intel reportedly has deep ties to the Chinese Communists," Cotton wrote in a post on X accompanying the letter. "U.S. companies who receive government grants should be responsible stewards of taxpayer dollars and adhere to strict security regulations. The board of @Intel owes Congress an explanation."

Electronic Arts faces a familiar challenge as it prepares to launch Battlefield 6 on October 10: breaking its dependence on the FIFA franchise, now called EA Sports FC, which drives roughly 70% of company profits despite disappointing sales this year. The company has poured unprecedented resources into Battlefield 6, treating it as a platform built for user-generated content rather than a traditional game release. Early signs appear promising -- the trailer hit nearly 5 million YouTube views in a week and shares climbed 5% after beta testing began -- but analysts remain cautious after last year's Dragon Age flop gutted subsidiary BioWare.

BrianFagioli shares a report from NERDS.xyz: PCI-SIG says PCI Express 8.0 will hit a raw bit rate of 256.0 GT/s, doubling what PCIe 7.0 offers. The spec is expected to be ready by 2028, and the goal is to support massive data loads from AI, machine learning, edge computing, and even quantum systems. The group says PCIe 8.0 will allow up to 1 terabyte per second of bidirectional throughput with a full x16 configuration. They're also looking at new connector designs, improving protocol efficiency, reducing power use, and maintaining backward compatibility.

alternative_right shares a report from Phys.org: Three nano-glass spheres cling to one another. They form a tower-like cluster, similar to when you pile three scoops of ice cream on top of one another -- only much smaller. The diameter of the nano cluster is ten times smaller than that of a human hair. With the help of an optical device and laser beams, researchers at ETH Zurich have succeeded in keeping such objects almost completely motionless in levitation. This is significant when it comes to the future development of quantum sensors, which, together with quantum computers, constitute the most promising applications of quantum research. As part of their levitation experiment, the researchers, led by adjunct professor of photonics Martin Frimmer, were able to eliminate the gravitational force acting on the glass spheres. However, the elongated nano object still trembled, similar to how the needle on a compass moves when settling into position. In the case of the nano cluster, the trembling motion was very fast but weak: the object made around one million deflections per second, each measuring only a few thousandths of a degree. This tiny rotational oscillation is a fundamental quantum motion exhibited by all objects, which physicists call zero-point fluctuation. To date, no one has been successful in detecting these tiny movements for an object of this size as precisely as the ETH researchers have now done. They achieved this because they were able to largely eliminate all motions that originate from the field of classical physics and obscure the observation of quantum movements. The ETH researchers attribute 92% of the cluster's movements in their experiment to quantum physics and 8% to classical physics; they therefore refer to a high level of quantum purity. And the records do not stop there: The researchers accomplished all of this at room temperature. Quantum researchers usually have to cool their objects to a temperature close to absolute zero (-273 degrees Celsius) using special equipment. This was not required here. The research has been published in the journal Nature Physics.

An anonymous reader quotes a report from New Scientist: People withAlzheimer's disease have lower levels of lithium in their brains, and giving lithium to mice with symptoms of the condition reverses cognitive decline. Together, the findings suggest that lithium deficiency could be a driver of Alzheimer's disease and that low-dose lithium medications could help treat it. [...] [Bruce Yanknerat Harvard University] and his colleagues analyzed levels of 27 metals in the brains of 285 people after they died, 94 of whom were diagnosed with Alzheimer's disease and 58 of whom had mild cognitive impairment, a precursor of the condition. The other participants showed no signs of cognitive decline at the time of their death. Lithium levels in the prefrontal cortex -- a brain region crucial for memory and decision-making -- were about 36 percent lower, on average, in people with Alzheimer's disease than in those without any cognitive decline. For those with mild cognitive impairment, lithium levels were about 23 percent lower. "We suspect that's due to a number of environmental factors: dietary intake, genetics and so forth," says Yankner. Yet there seemed to be another reason, too. In those with Alzheimer's disease, clumps of proteins called amyloid plaques contained nearly three times the amount of lithium as plaque-free regions of their brain. "Lithium becomes sequestered in these plaques," says Yankner. "We have two things going on. There is impaired uptake of lithium [in the brain] very early on and then, as the disease progresses, the lithium that is in the brain is further diminished by being bound to amyloid." To understand how this influences cognition, the team genetically engineered 22 mice to develop Alzheimer's-like symptoms and reduced their lithium intake by 92 percent. After about eight months, the animals performed significantly worse on multiple memory tests compared with 16 mice on a standard diet. It took lithium-deficient mice around 10 seconds longer to find a hidden platform in a water maze, for example, even after six days of training. Their brains also contained nearly two and a half times as many amyloid plaques. Genetic analysis of brain cells from the lithium-deficient mice showed increased activity in genes related to neurodegeneration and Alzheimer's. They also had more brain inflammation and their immune cells were less able to clear away amyloid plaques, changes also seen in people with Alzheimer's disease. The team then screened different lithium compounds for their ability to bind to amyloid and found that lithium orotate -- a naturally occurring compound in the body formed by combining lithium with orotic acid -- appeared to be the least likely to get trapped within plaques. Nine months of treatment with this compound significantly reduced plaques in mice with Alzheimer's-like symptoms, and they also performed as well on memory tests as normal mice. These results suggest lithium orotate could be a promising treatment for Alzheimer's. The findings have been published in the journal Nature.

Bruce66423 shares a report from the BBC: A man who is bringing a High Court challenge against the Metropolitan Police after live facial recognition technology wrongly identified him as a suspect has described it as "stop and search on steroids." Shaun Thompson, 39, was stopped by police in February last year outside London Bridge Tube station. Privacy campaign group Big Brother Watch said the judicial review, due to be heard in January, was the first legal case of its kind against the "intrusive technology." The Met, which announced last week that it would double its live facial recognition technology (LFR) deployments, said it was removing hundreds of dangerous offenders and remained confident its use is lawful. LFR maps a person's unique facial features, and matches them against faces on watch-lists. [...] Mr Thompson said his experience of being stopped had been "intimidating" and "aggressive." "Every time I come past London Bridge, I think about that moment. Every single time." He described how he had been returning home from a shift in Croydon, south London, with the community group Street Fathers, which aims to protect young people from knife crime. As he passed a white van, he said police approached him and told him he was a wanted man. "When I asked what I was wanted for, they said, 'that's what we're here to find out'." He said officers asked him for his fingerprints, but he refused, and he was let go only after about 30 minutes, after showing them a photo of his passport. Mr Thompson says he is bringing the legal challenge because he is worried about the impact LFR could have on others, particularly if young people are misidentified. "I want structural change. This is not the way forward. This is like living in Minority Report," he said, referring to the science fiction film where technology is used to predict crimes before they're committed. "This is not the life I know. It's stop and search on steroids. "I can only imagine the kind of damage it could do to other people if it's making mistakes with me, someone who's doing work with the community." Bruce66423 comments: "I suspect a payout of 10,000 pounds for each false match that is acted on would probably encourage more careful use, perhaps with a second payout of 100,000 pounds if the same person is victimized again."

An anonymous reader quotes a report from TechCrunch: Ron Deibert, the director of Citizen Lab, one of the most prominent organizations investigating government spyware abuses, is sounding the alarm to the cybersecurity community and asking them to step up and join the fight against authoritarianism. On Wednesday, Deibert will deliver a keynote at the Black Hat cybersecurity conference in Las Vegas, one of the largest gatherings of information security professionals of the year. Ahead of his talk, Deibert told TechCrunch that he plans to speak about what he describes as a "descent into a kind of fusion of tech and fascism," and the role that the Big Tech platforms are playing, and "propelling forward a really frightening type of collective insecurity that isn't typically addressed by this crowd, this community, as a cybersecurity problem." Deibert described the recent political events in the United States as a "dramatic descent into authoritarianism," but one that the cybersecurity community can help defend against. "I think alarm bells need to be rung for this community that, at the very least, they should be aware of what's going on and hopefully they can not contribute to it, if not help reverse it," Deibert told TechCrunch. [...] "I think that there comes a point at which you have to recognize that the landscape is changing around you, and the security problems you set out for yourselves are maybe trivial in light of the broader context and the insecurities that are being propelled forward in the absence of proper checks and balances and oversight, which are deteriorating," said Deibert. Deibert is also concerned that big companies like Meta, Google, and Apple could take a step back in their efforts to fight against government spyware -- sometimes referred to as "commercial" or "mercenary" spyware -- by gutting their threat intelligence teams. [...] Deibert believes there is a "huge market failure when it comes to cybersecurity for global civil society," a part of the population that generally cannot afford to get help from big security companies that typically serve governments and corporate clients. "This market failure is going to get more acute as supporting institutions evaporate and attacks on civil society amplify," he said. "Whatever they can do to contribute to offset this market failure (e.g., pro bono work) will be essential to the future of liberal democracy worldwide," he said. Deibert is concerned that these threat intelligence teams could be cut or at least reduced, given that the same companies have cut their moderation and safety teams. He told TechCrunch that threat intelligence teams, like the ones at Meta, are doing "amazing work," in part by staying siloed and separate from the commercial arms of their wider organizations. "But the question is how long will that last?" said Deibert.

Without providing specifics, President Trump said on Wednesday that he will impose a 100% tariff on imports of semiconductors and chips, but not for companies that are "building in the United States." CNBC reports: "We're going to be putting a very large tariff on chips and semiconductors," Trump said in the Oval Office on Wednesday afternoon. "But the good news for companies like Apple is if you're building in the United States or have committed to build, without question, committed to build in the United States, there will be no charge," he said. "So in other words, we'll be putting a tariff on of approximately 100% on chips and semiconductors. But if you're building in the United States of America, there's no charge." The remarks follow a recently announced commitment by Apple to invest another $100 billion in the U.S. over the next four years to boost manufacturing in the U.S.

A federal judge struck down California's strict anti-deepfake election law, citing Section 230 protections rather than First Amendment concerns. Politico reports: [Judge John Mendez] also said he intended to overrule a second law, which would require labels on digitally altered campaign materials and ads, for violating the First Amendment. [...] The first law would have blocked online platforms from hosting deceptive, AI-generated content related to an election in the run-up to the vote. It came amid heightened concerns about the rapid advancement and accessibility of artificial intelligence, allowing everyday users to quickly create more realistic images and videos, and the potential political impacts. But opponents of the measures ... also argued the restrictions could infringe upon freedom of expression. The original challenge was filed by the creator of the video, Christopher Kohls, on First Amendment grounds, with X later joining the case after [Elon Musk] said the measures were "designed to make computer-generated parody illegal." The satirical right-wing news website the Babylon Bee and conservative social media site Rumble also joined the suit. Mendez said the first law, penned by Democratic state Assemblymember Marc Berman, conflicted with the oft-cited Section 230 of the federal Communications Decency Act, which shields online platforms from liability for what third parties post on their sites. "They don't have anything to do with these videos that the state is objecting to," Mendez said of sites like X that host deepfakes. But the judge did not address the First Amendment claims made by Kohls, saying it was not necessary in order to strike down the law on Section 230 grounds. "I'm simply not reaching that issue," Mendez told the plaintiffs' attorneys. [...] "I think the statute just fails miserably in accomplishing what it would like to do," Mendez said, adding he would write an official opinion on that law in the coming weeks. Laws restricting speech have to pass a strict test, including whether there are less restrictive ways of accomplishing the state's goals. Mendez questioned whether approaches that were less likely to chill free speech would be better. "It's become a censorship law and there is no way that is going to survive," Mendez added.

An anonymous reader quotes a report from Ars Technica: The Library of Congress today said a coding error resulted in the deletion of parts of the US Constitution from Congress' website and promised a fix after many Internet users pointed out the missing sections this morning. The missing portions of the Constitution were restored to one part of the website a few hours after the Library of Congress statement and reappeared on a different part of the website another hour or so later. The Constitution Annotated website carried a notice saying it "is currently experiencing data issues. We are working to resolve this issue and regret the inconvenience." "Upkeep of Constitution Annotated and other digital resources is a critical part of the Library's mission, and we appreciate the feedback that alerted us to the error and allowed us to fix it," the Library of Congress said. We asked the Library of Congress for specific details on the coding error, but we received only a statement that did not include specifics. "Due to a technical error, some sections of Article 1 were temporarily missing on the Constitution Annotated website. This problem has been corrected, and the missing sections have been restored," the statement said. The deletion happened sometime in the past few weeks, as an Internet Archive capture shows that the text was still on the site until at least July 21. The deletions were being discussed this morning on Reddit and in news articles, with people expressing suspicions based on which parts of the Constitution were missing.

Chemical pollution is "a threat to the thriving of humans and nature of a similar order as climate change" but decades behind global heating in terms of public awareness and action, a report has warned. The Guardian: The industrial economy has created more than 100 million "novel entities," or chemicals not found in nature, with somewhere between 40,000 and 350,000 in commercial use and production, the report says. But the environmental and human health effects of this widespread contamination of the biosphere are not widely appreciated, in spite of a growing body of evidence linking chemical toxicity with effects ranging from ADHD to infertility to cancer. "I suppose that's the biggest surprise for some people," Harry Macpherson, senior climate associate at Deep Science Ventures (DSV), which carried out the research, told the Guardian. "Maybe people think that when you walk down the street breathing the air; you drink your water, you eat your food; you use your personal care products, your shampoo, cleaning products for your house, the furniture in your house; a lot of people assume that there's really great knowledge and huge due diligence on the chemical safety of these things. But it really isn't the case."

Parts of the Great Barrier Reef have suffered the largest annual decline in coral cover since records began nearly 40 years ago, according to a new report. BBC: Northern and southern branches of the sprawling Australian reef both suffered their most widespread coral bleaching, the Australian Institute of Marine Science (AIMS) found. Reefs have been battered in recent months by tropical cyclones and outbreaks of crown-of-thorns starfish that feast on coral, but heat stress driven by climate change is the predominant reason, AIMS said. AIMS warns the habitat may reach a tipping point where coral cannot recover fast enough between catastrophic events and faces a "volatile" future. AIMS surveyed the health of 124 coral reefs between August 2024 and May 2025. It has been performing surveys since 1986. Often dubbed the world's largest living structure, the Great Barrier Reef is a 2,300km (1,429-mile) expanse of tropical corals that houses a stunning array of biodiversity. Repeated bleaching events are turning vast swaths of once-vibrant coral white. Australia's second largest reef, Ningaloo -- on Australia's western coast -- has also experienced repeated bleaching, and this year both major reefs simultaneously turned white for the first time ever. Coral is vital to the planet. Nicknamed the sea's architect, it builds vast structures that house an estimated 25% of all marine species.

Two fundamentally different methods for measuring the universe's expansion rate continue to produce incompatible results -- with direct observations of receding galaxies yielding approximately 73 kilometers per second per megaparsec and cosmic microwave background radiation analysis producing closer to 67 km/s/mpc. The discrepancy, known as the Hubble tension, has strengthened annually for the past decadem, according to Duke University astronomer Dan Scolnic. The persistent disagreement prevents calculation of the universe's precise age or size. The Lambda-CDM model, which holds that dark energy and dark matter comprise 95% of the universe while visible matter constitutes just 5%, assumes dark energy's nature has remained constant since the Big Bang. Some theorists propose dark energy's potency changes over time, while others suggest the Milky Way sits within a comparatively empty region of space. A June study using gravitational lensing of quasar light, bypassing traditional distance measurements, matched the higher value. New telescopes including the Vera Rubin Observatory and Nancy Grace Roman Space Telescope may provide additional data. Past improvements in measurement precision have only reinforced rather than resolved the tension.

A new War of the Worlds adaptation starring Ice Cube has achieved a 0% critical rating on Rotten Tomatoes after arriving on Prime Video in late July. The science fiction film, produced by Universal Pictures during the 2020 pandemic using actors filming separately through video calls, features alien tripods emerging from meteors to attack Earth. The movie sat unreleased for approximately five years before streaming debut. Critics cite poor visual effects that "wouldn't pass muster on a whimsical Snickers ad" and performances where actors appear to be "performing in a Zoom-style vacuum." The film was shot using screenlife format with most action unfolding on computer screens.
