An anonymous reader quotes a report from Scientific American: Microplastics are a source of extreme concern for health: the presence of these tiny pieces of plastic has been linked to heart attacks, stroke, dementia and brain tumors. But what drives these associations is unclear. Now a study published in Nature offers a tantalizing clue: microplastics interact with water, generating highly reactive molecules. When microplastics come into contact with water, the water near their surface can become chemically active, generating highly reactive species that can modify nearby substances, including biologically important molecules. As plastics wear down to microscopic sizes, their surface-to-volume ratio increases dramatically. For example, when a credit card is fragmented into particles some 10 microns in diameter, there is a more than 200-fold increase in its surface area, says Wei Min, a chemist at Columbia University and one of the senior authors of the study. As a result, any chemical activity is amplified. Min and his colleagues examined various microplastics -- including polystyrene, polyethylene, polyvinyl chloride, polypropylene and polyethylene terephthalate. Plastic surfaces are hydrophobic, meaning they repel water, Min says. Thus, water molecules cannot form the hydrogen bonds they maintain in liquid form. That changes molecular arrangements, and, in turn, the change influences the local electrical environment and chemical reactivity. The presumed chemical inertness of bulk plastics overlooks the toxicity of their fragmented microscale forms. "For microplastics, this is especially important because fragmentation creates enormous amounts of new surface area," Min says. In past research, microplastics have been shown to cause inflammation, oxidative stress and decreased mitochondrial activity. The new study provides a possible mechanism for this, showing that plastic-water interfaces can perturb proteins, cell membranes, and more. How this might contribute to damage in living tissues in humans is still unclear, Min says. "Ultimately, we hope to connect fundamental interfacial chemistry with quantitative measurements of biological effects, which would help us better understand potential health risks," he adds.

Astronomers have identified what may be the first genuinely green star, a white dwarf called WD J1330+6435 located about 326 light-years from Earth. Space.com reports: The researchers found that some dead star white dwarfs can go a little green around the gills after snacking on orbiting planets. An example of this is WD J1330+6435, a cool white dwarf located around 326 light-years away, which has been accreting rocky material from a planetary companion. This has enriched its atmosphere with calcium, lithium, and sodium, and the team's model suggests this would have led WD J1330+6435 to adopt a green hue. [...] The researchers think that no other star, living or dead, has ever been credibly reported as green. That makes WD J1330+6435 the first known genuinely green star. "The traces of sodium in the atmosphere of this white dwarf absorb the orange part of the spectrum, leaving behind a ghostly green glow," Hollands said. "Imagine standing on a planet and looking up at a green star. It feels like something out of science fiction." The researchers also discovered what may be the reddest star ever observed, the white dwarf WD J1011+2845, located just 48 light-years away. The findings have been published in the journal RAS Techniques and Instruments.

An anonymous reader quotes a report from Wired: Prediction market boosters often tout the platforms as barometers of public opinion, or even "truth machines" offering a clearer picture of where things are headed than polling or other data. In 2024, for example, Kalshi beat many pollsters in forecasting the outcome of the US presidential race. But their trading activity can also tell more perplexing stories. Two global election markets on Polymarket's offshore platform, for instance, generated over $600 million in trading volume, far more than most political markets typically attract. Most of the activity took place buying and selling contracts tied to long-shot candidates who ultimately did not win. The report focuses on suspicious trading activity surrounding elections in Ethiopia and Romania, where researchers uncovered $284 million in questionable trades tied to Ethiopia's election and periods when 99.6% of trading volume in a Romanian election market was flagged as suspected "wash trading." According to Wired, "wash trading is a type of market manipulation in which accounts repeatedly buy and sell assets to create the illusion of heavy trading activity, when in reality, money is simply moving back and forth." Some accounts may also be artificially inflating their activity to qualify for potential cryptocurrency token rewards, a practice known as "activity farming." In response to the Ethiopian trading activity, Polymarket told Wired that the company "immediately flagged this activity, investigated, and blocked the accounts from trading." The company did not explain why the suspicious trades were allowed to continue for months before action was taken.

The collaborative reverse-engineering site decomp.dev is shutting down, with its administrator saying AI has made game decompilation so fast and accessible that the community's human-driven model has effectively broken down. "The administrator of the website said that it has become impossible to keep track of which projects are primarily human-led and which ones are done by AI," reports 404 Media. From the report: "Historically, matching decompilation has been a brutally difficult, time consuming task, on the scale of years for any moderately-sized game with a number of active contributors," the pseudonymous admin of decomp.dev, who goes by Encounter, wrote on the site. But recent frontier AI models like GPT-6-Astra have made it trivially easy to decompile a game: "They are significantly better at following complex directions, cross-referencing resources for symbols or debug information, and writing natural code with enough guidance," Encounter wrote. "It is now clear that, with the right guidance, human input, and code reviews, AI can expedite the decompilation process in a significant way. What is also now clear is that the community aspect of decompilation has been broken."

Tencent says AI agents used to evaluate third-party models engaged in unintended web-browsing behavior while trying to retrieve data from Alibaba's Amap service. The announcement marks a rare acknowledgment of "rogue" agent activity by a major Chinese tech company. Reuters reports: Tencent Hunyuan, the company's artificial intelligence unit, said in a post on X that the activity did not originate from its Hunyuan models. Its review found no evidence of deliberate targeting or coordination, it said. The Swarmchasers researchers said the agents sought information such as the commonly used entrances at Chinese parks, museums and zoos. [...] Swarmchasers said it used the word "rogue" to describe agents taking actions outside their intended scope or completing a task in unintended ways. After routine automated requests were blocked, the agents tried other methods, including public web tools that could open pages and run code, routing requests through other websites and using Amap keys and security codes found in publicly available software code. Swarmchasers said it found no evidence that the agents breached Amap's main anti-bot safeguards. Most of the 2,818 attempts it recorded either failed or returned anti-bot pages, login screens or blank results. Some requests returned information through cached pages and intermediary services, including data on visitor arrivals at Chengdu Zoo, Swarmchasers said. The researchers said they could not determine whether an agent read the result or completed its task.

Valve has released a new Steam Client beta that finally moves the Linux client to 64-bit architecture, while also placing it inside a containerized Steam Runtime environment. However, Linux users still need 32-bit libraries and graphics drivers for compatibility, meaning fully 64-bit-only systems remain unsupported. VideoCardz.com reports: Valve's updated requirements explicitly state that 64-bit-only installations are not supported. Systems must still provide both 32-bit and 64-bit libraries and graphics drivers, including multilib support. The new client also requires Linux kernel 5.6 or newer and glibc 2.31 or newer. The update also introduces Steam Achievement Sets, a feature we covered earlier that allows developers to organize achievements into separate groups for base games, DLCs and seasonal content. Players can complete individual sets without losing their existing completion status when developers add more achievements. Valve has also updated the achievements page to display progress across these groups. The 64-bit Linux client and Achievement Sets are currently available through the Steam Client Beta. Valve has not confirmed when these changes will reach the stable Linux release. Until then, users on the regular Steam client will continue using the existing architecture.

Meta is facing criticism over updated commercial terms taking effect October 30 that could give the company broad permission to scrape content from websites linked to business accounts and use it to train AI. Legal experts warn the changes could undermine lucrative AI licensing deals for news publishers, with no direct opt-out for businesses that accept the terms. Ars Technica reports: As Nieman Lab reported Thursday, this will affect all business accounts but is particularly shocking for news publishers who could perhaps charge Meta millions in licensing fees to continually access their articles for AI training. Currently news organizations are fighting a battle with OpenAI over whether such training without licensing is fair use, and Meta's terms seemingly risk granting it sweeping permissions, no matter which way the court leans. "While journalism isn't the only industry that will be affected by this update, virtually every news organization has at least one Meta business account, including Nieman Lab," the lab said. [...] Notably, there is no mention of AI, but it's inferred from a single use of the word "train" and references to automated scraping and crawling. Meta's spokesperson told Nieman Lab that Meta has no plans to use the terms as a legal basis to ignore robots.txt instructions that block scraping on news sites. The company still allows news organizations to opt out of scraping and provides instructions on how to block crawling. A spokesperson told Ars that "there is no change to how Meta uses web crawlers; any suggestion to the contrary is false." However, should courts affirm that AI training non-news articles is fair use, news organizations question if Meta's stance might change, and the terms could be used to freely grab access to content by legally overriding robots.txt instructions.

An OpenAI research model reportedly accessed an Ethereum testnet wallet without permission in order to complete a coding task during internal training. "This case shows that a model can substitute its own judgment about likely harm for the account holder's permission, then act on that judgment without authorization," OpenAI wrote. Engadget reports: The incident, which occurred on June 26, happened while a GPT-5.6 Sol model was in internal training. The task involved updating a crypto trading prototype and deploying contracts (publishing special code) on an Ethereum test network called Sepolia. Payment of a network fee is required for such contracts, but OpenAI "supplied no funded wallet and gave no permission to spend funds from an account the model found independently," OpenAI said in the report. The lack of funds at first stymied the agent, but it was not to be discouraged. The model reasoned that it could use public developer recovery phrases (similar to those you might use to recover a password) to access keys from unauthorized accounts. It tracked down 362 addresses open to that avenue of attack and found one that held enough Sepolia ETH to finish its deployment (to be clear, Sepolia ETH has no value outside of testing). Like many criminals, the agent reasoned that someone must have left this access open for automated draining of the ETH "faucets." It also figured that the crypto was effectively "abandoned" and "valueless," according to OpenAI's misalignment records. The piece de resistance was that the agent "did not disclose that it had selected a funded account through a public recover phrase or spent that account's balance," OpenAI said. To prevent similar events in the future, the company is now monitoring all traffic and paging security if live internet access is detected.

An anonymous reader quotes a report from Reuters: Private credit's expanding role in financing AI infrastructure faced one of its clearest market tests this week as CoreWeave's bonds fell to distressed levels, raising questions about how lenders are pricing a boom built on chips, data centers and customer contracts. CoreWeave has about $50 billion of debt, according to LSEG data, making it one of the largest borrowers linking private credit to the AI buildout. The cost of insuring its debt against default climbed to about 1,200 basis points this week, while yields on some of its bonds rose to roughly 15% to 16%, signaling sharply increased investor concern over its credit risk. "There is still a price. Investors are still comfortable financing it, but they're demanding more compensation for it," said James Martin, senior US credit strategist at SMBC, referring to projects further from completion. Carlyle estimates that private credit could finance roughly $1 trillion of the AI infrastructure buildout but warns that aggressive lending could create concentration risks similar to those seen in software lending. "The clearest lesson is not to avoid AI compute exposure, but to set concentration limits before the buildout accelerates further, not after," Carlyle said.

Apple's first foldable iPhone, the $1,999 iPhone Duo, sold out within minutes of preorders opening, with every configuration slipping to late January 2027. "All color and storage combinations show an estimated ship date of January 25," reports 9to5Mac. "Some users are even seeing January 29 for their estimated shipping date." From the report: This is a combination of strong demand and severely constrained supply for iPhone Duo. It's impossible to know the exact balance between the two, though. Going into the launch, there were multiple reports suggesting iPhone Duo would be in short supply as Apple was still ramping up production. A report from Nikkei Asia last month said Apple was making just a few hundred iPhone Duo units per day, significantly behind the ramp of a normal iPhone launch.

An anonymous reader quotes a report from BleepingComputer: A proxyjacking campaign has impacted devices in 34 countries, monetizing victims' internet connections through a commercial residential proxy network. The operator installed Pawns.app, a legitimate bandwidth-sharing application that lets users earn money by sharing their internet connections, on devices without the owners' consent. Pawns.app account holders are rewarded for allowing traffic from other users to flow through their network, provided it runs on trusted, non-blocking IP addresses. By installing the app on multiple systems, the attacker likely accumulated larger payouts. Threat intelligence company GreyNoise discovered the campaign while investigating suspicious activity at an unnamed organization, and identified at least 143 compromised devices worldwide. According to researchers, the attacker exploited known vulnerabilities in D-Link ShareCenter NAS (CVE-2024-3272 and CVE-2024-3273), Ubiquiti UniFi Video NVR (CVE-2021-44228), and SAP NetWeaver Visual Composer (CVE-2025-31324) to install the Pawns.app software. Hikvision and Dahua DVR/NVR devices were also targeted, though the specific vulnerabilities exploited were not identified. In some cases, the report says the attackers configured SSH key authentication to maintain backup access to the compromised systems.

Timekeepers have officially voted to eliminate the leap second, allowing Coordinated Universal Time to drift as much as one hour from Earth's rotation before a correction is needed. The change ends decades of occasionally adding or subtracting seconds and replaces it with a hypothetical "leap hour" that likely wouldn't be necessary for hundreds or even thousands of years. Smithsonian Magazine reports: "It's kind of a philosophical discussion, because if a leap hour happens, it won't be for a very, very long time," Christian Bizouard, director of the IERS Earth Orientation Center in France, tells the Guardian's Ian Sample. "What we are doing is pushing back the decision." The move caps off 30 years of debate, as the leap second has been highly controversial in the world of timekeeping. Leap seconds aren't nearly as smooth of a fix as leap years are, and they can cause computer and website issues. Reddit famously crashed when a leap second was added on June 30, 2012. It's "always been a problem," Judah Levine, a former researcher at the NIST's Time and Frequency Division, tells Scientific American's Emma Gometz. Instead of adding the entire second all at once, companies such as Google and Meta add the extra time in smaller segments in a tactic called "smearing," according to the Conversation. It's not a simple task, however, and companies that employ smearing have long lobbied to get rid of the leap second. What's more, with Earth's recent spin acceleration, timekeepers around the world were facing the possibility of the world's first negative leap second, in which a second would be subtracted from UTC. This sparked fears, akin to those surrounding Y2K, that our modern technologies wouldn't be able to handle such a change. "It's never happened before, and therefore the software for that has never been tested," Darryl Veitch, a researcher who leads the Timing Lab at the University of Technology Sydney, tells the Australian Broadcasting Corporation's Ellen Phiddian. But others argued that it wouldn't be much of a problem. The vote means that in the future, UTC will be allowed to diverge from astronomical time more than ever before.
