Science Daily reports: Researchers showed that unencrypted signals routinely exchanged between WiFi devices and routers can be used to create radio-based images of people and recognize them within seconds. In tests involving 197 participants, the system identified individuals with nearly 100% accuracy, even from different angles and regardless of how they walked. "By observing the propagation of radio waves, we can create an image of the surroundings and of persons who are present," says Professor Thorsten Strufe from KASTEL, KIT's Institute of Information Security and Dependability. "This works similar to a normal camera, the difference being that in our case, radio waves instead of light waves are used for the recognition," explains the cybersecurity expert. Because the technique analyzes radio waves moving through a space, a person does not need to have a phone, smartwatch, or other WiFi enabled device with them. "Thus, it does not matter whether you carry a WiFi device on you or not." Even turning off your own device would not necessarily prevent the system from working. "It's sufficient that other WiFi devices in your surroundings are active...." Connected devices routinely send information back to the router to help optimize wireless communication. These signals, known as beamforming feedback information (BFI), are transmitted without encryption, meaning that anyone within range can potentially read them. By analyzing that information, the system can generate images of people from multiple viewpoints. Those images can then be used to determine a person's identity. Once the machine learning model has already been trained to recognize individuals, the identification process takes only a few seconds.

When Anthropic instructed three agents to migrate a Python backend, but telling each agent to perform the migration in a different language, "We consistently saw a multiagent turf war," they wrote Thursday: All of the models we tested quickly assumed that others were purposefully impeding their work, and began to sabotage others while protecting their own contributions. In fact, they sabotaged others with increasingly aggressive, self-replicating malware. This included disabling the Unix accounts of the other agents, writing automated scripts that found and killed competing processes on a loop, and deploying malicious code that was disguised as belonging to another agent. In many runs, one agent settles the conflict by force via access-revocation (e.g., sudo/group removal, account lock, nologin, SSH denial). In others, some agents settle into passivity: they give up and refuse to escalate further. Agents sometimes manage to communicate their goals and coordinate: they recognize others' motivations as conflicting directives rather than hostility, and subsequently break out of the conflict loop in order to stop escalating indefinitely. In many of these successful episodes, they write commit messages or markdown files apologizing for malicious behavior and coordinate a truce. They clean up their malicious code, clarify the nature of the conflict, and ask for a human to intervene... In several episodes with Mythos 5, we observe an emergent behavior where the agents propose and run a tournament for application performance in each language. In the example above, the Rust agent strategizes about bake-off metrics that appear neutral enough for the others to agree to this mechanism, yet would likely favor Rust: one thinking trace warns to be "careful not to be seen as metric shopping". Ultimately, the Golang/TypeScript losers gracefully concede codebase ownership to the Rust agent, giving up on their original user directives under their self-negotiated commitment device. One problem is that AI agents do reward hacking, Anthropic notes, while current institutions "are designed by and for people, resting on assumptions about the sufficiency of oversight at human speed... As autonomous agents become more and more prevalent in the world and operate in ever-more demanding settings, it is crucial that they learn how to effectively coordinate." In addition to everything else, the agents struggled with a lack of clearly defined hierarchy, Anthropic points out. "Nothing above suggests that these failures are permanent — but nothing suggests they will fix themselves, either..." They argue a fix "takes two forms: environments that exert the kinds of social pressure that evolution exerted on us, and social computing systems redesigned for actors that can self-replicate and self-improve. These are open problems in interaction and mechanism design, and our experiments here provide early evidence that new solutions are necessary." "The AI models being tested in this case were Sonnet 4.6, Sonnet 5, Opus 4.6, Opus 4.8, Mythos Preview, and Mythos 5," notes Business Insider, adding that Sonnet 4.6 and Opus 4.6 "were the most combative, settling about 60% of their runs by force instead of truces or passivity." Anthropic argues there's a clear case for researching this phenomenon — especially since "The volume of agent-agent interaction could plausibly exceed that of human-human and human-agent interactions before the world understands the conditions for making such interactions go well."

Europe is facing its fifth round of dangerously high temperatures this summer, the New York Times reports. Now climate scientists wonder if global warming is doing more than raise temperatures... The weather patterns that create heat domes aren't new, but today they arise on top of the warming caused by greenhouse gas emissions. That makes it more likely that heat waves reach record-shattering temperatures for long stretches. But other environmental changes — natural, human-influenced or both — might also be causing heat domes to become more frequent and longer lasting. And it's these changes that scientists around the globe are trying to puzzle out. One change has to do with the Arctic. The differences in temperature between the hot Equator and the frigid far north help keep weather moving around the Northern Hemisphere. But with the top of the world now warming at several times the pace of the rest of the globe, those temperature gradients are narrowing. That might be causing the movements of weather systems to become more sluggish, producing more persistent heat waves. In Europe, reduced air pollution could be having a similar effect. Industrial emissions can contain particles called aerosols that reflect sunlight. Curbing aerosols has improved air quality, but it may also have altered the way air moves across the continent. Scientists haven't come to firm conclusions about how these shifts might be affecting European summers, said Antje Weisheimer, a climate scientist at the University of Oxford. The complex, fine-scale interactions in the atmosphere that drive weather dynamics are tough to capture in computer simulations, Dr. Weisheimer said. "It's tricky," she said. "We're making small progress." Dim Coumou, a professor of climate science at the Dutch university VU Amsterdam, sees artificial intelligence as one way forward. In a recent study, he and his colleagues used an A.I. algorithm to help a weather model better predict summer temperatures in Europe. They not only improved the model's forecasts; they also discovered why some of the model's predictions had been off: It misrepresented the way conditions in the western Pacific Ocean influenced atmospheric patterns that eventually made their way to Europe. With A.I., "we can also learn what the climate models are missing," Dr. Coumou said.

A "massive influx" of jellyfish forced Electricite de France SA to shut three units at its Gravelines nuclear power plant this week and reduce output at a fourth, reports Bloomberg. Just as summer temperatures surged, 3.2 gigawatts went offline — and the power utility was already facing cuts other nuclear sites as high temperatures reduced the river water available for cooling. More details from ScienceAlert: As Politico reports, the Gravelines nuclear power plant spent hundreds of thousands of euros in 2025 to stop this happening again, only to see a repeat 12 months later... Increasing temperatures in the water can produce more of the plankton and animals that jellyfish feed on, as well as accelerating life cycles and extending breeding seasons.... It's not just jellyfish that have a habit of disrupting human energy infrastructure. Last year in Connecticut, a single raccoon caused more than a thousand power outages, as reported by CT Insider. It's not clear exactly what the raccoon did, but we do know it somehow got into a substation and caused damage to the equipment in there. The unwitting act of sabotage left more than 2,500 customers in the area without power at one stage — though repairs were swiftly carried out. Reuters reported Tuesday on how the French utility responded to their jellyfish swarm: EDF has installed fixed cameras at the intake canals and on the filter drum screens to detect any incoming blockages as soon as possible, an engineer told Reuters... The company has also partnered with a French fishing organisation and a sea rescue organisation, which monitor for swarms and can raise an alert to launch targeted trawling operations by fishermen to reduce the swarm's density before it reaches the plant, the engineer said. The fishing boats were deployed [last] Saturday after an initial alarm was raised, limiting the impact from the swarm. The jellyfish that are already on site are being removed with vacuum trucks, he said. No new jellyfish are arriving, so cleanup is finishing, which should lead to a quick restart of the units, they added... Scientists warn such events could become more common due to factors including global warming, the arrival of invasive species, habitat loss of predators and over-fishing.

Less than a year ago he was the #1 richest man in the world. 10 weeks ago he was #2. But yesterday Larry Ellison dropped to #8, Forbes reports, falling behind Nvidia CEO Jensen Huang. Ellison's net worth is now estimated at just $192.6 billion — after a $104 billion decline: Shares of Oracle plunged roughly 54% between hitting a high of just over $250 on June 1 to a low of $114.50 on July 28, though the stock rebounded slightly to $150.52 as of Friday. A decline followed Oracle telling investors it expected to raise $40 billion through debt and equity financing, with capital expenditures surging 162% to $55.7 billion and spending expected to top $95 billion by fiscal 2027. Jacob Bourne, an analyst at eMarketer, told Reuters there are broader concerns about how Oracle would fund its capital spending to match its revenue projections, and Bank of America analysts separately flagged in a note cautioning that more than 50% of Oracle's remaining performance obligation comes from OpenAI. Melius Research analysts wrote last month that Oracle's spending plans may not hold if OpenAI or Anthropic demands more computing capacity. S&P Global also downgraded Oracle's credit rating in July, arguing the firm's "rapidly expanding" AI infrastructure business could pay off, but may be too expensive and could weaken Oracle's financial position in the meantime. $443 billion. That's how much Oracle's market valuation has dropped since peaking at $877.1 billion in September, hitting $433.5 billion as of Friday... Oracle, once viewed as a potential winner of the booming AI infrastructure buildout, has since raised concerns among investors who appear to view the firm as taking on too much financial risk to fund its projects. Wall Street has cautioned that mega-cap tech firms may be taking on too much spending to match growing demand for AI products, with firms like Amazon expecting to spend more than $200 billion. Oracle's backlog has exploded to $638 billion, but more than half is reportedly associated with OpenAI, and some analysts have cautioned that most of those funds may not be guaranteed.

"An engineering director at Google said four years ago that AI would deliver a four-day work week by 2025," remembers the BBC. And earlier this year OpenAI "formally urged companies to start testing out a four-day work week (with no change in pay), claiming that AI will soon be able to speed up so much human labour that the corporate world should prepare itself." However, a former OpenAI technical employee who left the company last year told the BBC the firm never actually trialled the four-day work week it suggested others should try while they were there. Instead, the person described what was often a gruelling work culture marked by frequent "crisis meetings", working on weekends, and "super cut-throat" performance reviews that would see colleagues suddenly let go... [T]he former OpenAI employee said they would put in at least 70 hours a week, much more than they did in previous tech jobs... Other companies have also pushed the idea that AI will effectively reduce the number of hours people need to work, for better or worse. [At OpenAI and Anthropic] sprints can stretch on for many weeks and top 90 hours of work in a seven-day period, tech workers that the BBC spoke to for this story said... At Meta, workers said they have been abruptly pushed onto teams this year doing AI work being treated as urgent... The hours on such teams at Meta are often long, with staff working into the night, on weekends, and feeling they are "on call" during the hours they are not working, according to descriptions of the work from the current and former employees... Some new research suggests that AI tools are making people's workloads even more burdensome. A study out of UC Berkeley followed hundreds of workers at a US tech company for eight months as they used AI. It found the employees "worked at a faster pace, took on a broader scope of tasks, and extended work into more hours of the day"... The UC Berkeley research found that the workload of tech employees was expanded in part because of the need to constantly check the output of AI tools. In the article Neil Thompson, an innovation scholar at MIT, pointed out a problem with estimates that AI will ease the workload on humans. "People assume that 20% less work means four-day weeks. But new work emerges." The BBC also points out helpfully that "there are no limits in the U.S. on how many hours a person over the age of 16 can work." (While in the UK and Europe, "laws limit a working week to 48 hours, including overtime.") Thanks to long-time Slashdot reader hadleyburg for sharing the article.

It's not just RAM prices that are going up, writes CNET. "Reports suggest the cost of Windows licenses for manufacturers is rising by up to 10%." Several sites that closely follow Microsoft news, including Windows Central and Windows Latest, have published articles citing a report from Taiwan's Economic Daily News that claims some PC manufacturers are seeing a 7% to 10% increase in the cost of Windows 11 licenses... Because they buy licenses in bulk, they get a sizeable discount over what a consumer would pay for a new copy of Windows 11. But given the existing cost pressures from other components, a big Windows 11 price hike could lead them to pass on some of the added cost to PC buyers. According to the EDN story, PC makers could raise prices by about 5% over the next quarter due to the reported Windows price hike. .. A translated version of the Economic Daily News article contains information from an unnamed PC brand executive. It says that while Microsoft typically raises licensing costs every year by single-digit percentages, that hike has reached 7% to 10% this year, a significant increase. "A representative for Microsoft declined to comment on the report," according to the article. But it also notes that three weeks ago laptop maker Framework blamed price hikes and reconfigurations for some of their models on processor, memory, storage, "and other silicon costs — but also "an increase in Windows license costs."

"The European Union's Copernicus climate monitoring service confirmed Monday that June and July were the hottest on record in western Europe," .according to a report from the CBC. "The period saw an estimated 25,000 heat-related deaths." CNN has before-and-after photos of Europe's dried rivers, calling it "a crisis so dire it can be seen from space" River levels are so low that commercial ships have had to reduce their loads by as much as 80% to avoid running aground. It's disrupting supply chains and making shipping more expensive. Other effects of Europe's drying rivers The BBC reports that Romania has "shut down its only nuclear power station because of extremely low water levels in the Danube river." A bridge built in the year 39 AD by the Roman emperor Caligula "is usually entirely underwater," reports CNN, but this year full blocks of the ancient structure are visible, giving archaeologists a rare opportunity to study it." The reports adds that drying Tiber has also now also revealed formerly submerged e-bikes, scooters, refrigerators and a car." The CBC reports a dozen Nazi warships scuttled in a river during the Second World War are now resurfacing as water levels plunge. "Elsewhere, the drying Danube has revealed a German military motorcycle in Hungary, an unexploded 700-kilogram British bomb in Slovakia, and what are believed to be the ancient remains of a mammoth in Bulgaria."

This week Meta CEO Mark Zuckerberg published a 6,500 word open letter titled "The Future is for Everyone". But the BBC is more interested in why big tech executives keep writing manifestos about AI: [Zuckerberg's] vision echoes what AI leaders have expressed in various forms: the product they are building is among the "most important technologies in history." Marc Andreessen, co-founder of early web titan Netscape, perhaps started this trend in 2023 with a 5,000-word essay he called "The Techno-Optimist Manifesto", which argued innovation was the way to solve life's problems... As the International Monetary Fund warns AI could affect nearly 40% of jobs and worsen global financial inequality, Zuckerberg says he believes there will be an abundance of jobs in the future. "I do not understand why anyone who believes that AI will eliminate most jobs and much of humanity's relevance would rush to build that future." Never mind that Zuckerberg's Meta has cut 10% of its global workforce — about 8,000 jobs — as the company reorganizes to focus on AI. Zuckerberg's manifesto is the latest to land in our social media feeds in an effort to put a positive spin on AI. In 2024, ChatGPT-maker OpenAI boss Sam Altman released a manifesto called "The Intelligence Age", a sweeping expression of optimism about the tech's potential... That same year, in a manifesto titled "Machines of Loving Grace", Anthropic CEO Dario Amodei touted the potential of AI to transform everything from healthcare to politics. So what's going on with these tech executives' manifestos? Economics blogger Noah Smith suggested to the BBC "they all feel like it's such an important moment that it's incumbent upon them to do whatever they can to shape the direction that this technology is going." Although he does see some value in their engagement with important issues. "Should we open-source something that has the ability to kill humanity? If you don't take that seriously, you're just a fool." But Rob Lalka, a business professor at Tulane University, had a different explanation for the BBC: Lalka said the timing of Zuckerberg's manifesto coincides with rising anger over AI's impact on everything from jobs to the environment. And while tech journalists and academics might pore over them trying to glean nuggets of meaning, these executive manifestos are not necessarily landing with the general public. "They're trying to make the case that the positives will far outweigh some of those negatives that the public backlash is pointing out," he said. "But I think a lot of the reasons for optimism are still yet to be seen."
