Simon Sharwood reports via The Register: Chinese researchers have created a drone that weighs just over four grams -- less than a sheet of printer paper -- and may be able to fly indefinitely. Documented in a paper published last week in Nature, the drone uses an electrostatic motor that weighs just 1.52 grams and is powered by solar cells that produce 4.5V. The paper asserts that the drone's design has a lift-to-power efficiency two to three times better than that found in traditional drones. The authors suggested that if rechargeable batteries can be added, the craft could be capable of 24-hour flying operations.

Rosemary Fowler, a pioneering physicist who discovered the kaon particle during her doctoral research in 1948, has been awarded an honorary doctorate from the University of Bristol -- 75 years after she left her PhD to raise a family. The Guardian reports: Rosemary Fowler, 98, discovered the kaon particle during her doctoral research under Cecil Powell at the University of Bristol in 1948, which contributed to his Nobel prize for physics in 1950. Fowler's discovery helped lead to a revolution in the theory of particle physics, and it continues to be proven correct -- predicting particles such as the Higgs boson, discovered at Cern in Geneva, Switzerland. But she left university without completing her PhD to marry fellow physicist Peter Fowler in 1949, a decision she later described as pragmatic after she went on to have three children in a time of postwar food rationing. At 22, Fowler spotted something when viewing unusual particle tracks -- a particle that decayed into three pions, a type of subatomic particle. She said: "I knew at once that it was new and would be very important. We were seeing things that hadn't been seen before -- that's what research in particle physics was. It was very exciting." The track, later labelled K, was evidence of an unknown particle, now known as the kaon or K meson. The K track was the mirror image of a particle seen before by colleagues in Manchester, but their track decayed into two pions, not three. Trying to understand how these images were the same, yet behaved differently, helped lead to a revolution in the theory of particle physics. The year after the discovery, Fowler left university having published her discovery in three academic papers.

An anonymous reader quotes a report from MIT Technology Review: Researchers from Google have built a new weather prediction model that combines machine learning with more conventional techniques, potentially yielding accurate forecasts at a fraction of the current cost. The model, called NeuralGCM and described in a paper in Nature today, bridges a divide that's grown among weather prediction experts in the last several years. While new machine-learning techniques that predict weather by learning from years of past data are extremely fast and efficient, they can struggle with long-term predictions. General circulation models, on the other hand, which have dominated weather prediction for the last 50 years, use complex equations to model changes in the atmosphere and give accurate projections, but they are exceedingly slow and expensive to run. Experts are divided on which tool will be most reliable going forward. But the new model from Google instead attempts to combine the two. "It's not sort of physics versus AI. It's really physics and AI together," says Stephan Hoyer, an AI researcher at Google Research and a coauthor of the paper. The system still uses a conventional model to work out some of the large atmospheric changes required to make a prediction. It then incorporates AI, which tends to do well where those larger models fall flat -- typically for predictions on scales smaller than about 25 kilometers, like those dealing with cloud formations or regional microclimates (San Francisco's fog, for example). "That's where we inject AI very selectively to correct the errors that accumulate on small scales," Hoyer says. The result, the researchers say, is a model that can produce quality predictions faster with less computational power. They say NeuralGCM is as accurate as one-to-15-day forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF), which is a partner organization in the research. But the real promise of technology like this is not in better weather predictions for your local area, says Aaron Hill, an assistant professor at the School of Meteorology at the University of Oklahoma, who was not involved in this research. Instead, it's in larger-scale climate events that are prohibitively expensive to model with conventional techniques. The possibilities could range from predicting tropical cyclones with more notice to modeling more complex climate changes that are years away. "It's so computationally intensive to simulate the globe over and over again or for long periods of time," Hill says. That means the best climate models are hamstrung by the high costs of computing power, which presents a real bottleneck to research." The researchers said NeuralGCM will be open source and capable of running on less than 5,500 lines of code, compared with the nearly 377,000 lines required for the model from the National Oceanic and Atmospheric Administration (NOAA).

The Japan Newspaper Publishers and Editors Association claims that AI-powered search engines by U.S. tech giants like Google and Microsoft likely infringe on copyright by using news articles without permission. Therefore, they're urging the Japanese government to quickly review and revise intellectual property laws to address these issues. Kyodo News reports (translated in English): The association argued in the statement that while traditional search engines direct users to various copyrighted material available online, AI search engines disclose the content, making them a completely different type of service. While stressing that in many instances, the essential content of the referenced article is reprinted in its entirety and therefore constitutes copyright infringement, the association also highlighted the issue of "zero-click searches," where users do not visit the source site. It warned that the lack of traffic could lead to the diminution of news organizations' reporting activities, which would then have a negative impact on democracy and culture. The statement also expressed concern over potential inaccuracies in responses generated by AI search engines, which could give the impression that the source articles themselves were erroneous and damage the credibility of news organizations. The association added that providing AI search engine services without obtaining permission to use the source articles could violate the antimonopoly law. "There are many reasons AI companies are attracted to Japan, including the need for its companies to rapidly develop their digital capabilities and the country's declining population, which is very open to AI," said Yutaka Matsuo, a professor at Tokyo University and chair of the government's AI council, in a statement to the Financial Times. "One other attraction is that AI companies are permitted to learn from information without infringing copyright laws," he added. The Financial Times says the push to bring AI companies to Japan has raised alarm for some content creators who worry their work isn't being protected. "As it relates to generative AI, Japan's existing Copyright Act does not contribute to protecting creators. In fact, it is focused on restricting the rights of creators," the Japanese Society for Rights of Authors, Composers and Publishers said in a statement.

Azure used to be a cloud platform dedicated to Windows. Now, it's the most widely used operating system on Microsoft Azure. The New Stack's Joab Jackson writes: These days, Microsoft expends considerable effort that Linux runs as smoothly as possible on Azure, according to a talk given earlier this year at the Linux Foundation Open Source Summit given by two Microsoft Azure Linux Platforms Group program managers, Jack Aboutboul, and Krum Kashan. "Linux is the #1 operating system in Azure today," Aboutoul said. And all must be supported in a way that Microsoft users have come to expects. Hence, the need for the Microsoft's Linux Platforms Group, which provides support Linux to both the internal customers and to Azure customers. These days, the duo of engineers explained, Microsoft knows about as much as anyone about how to operate Linux at hyperscale. [...] As of today, there are hundreds of Azure and Azure-based services running on Linux, including the Azure Kubernetes Service (AKS), OpenAI, HDInsight, and many of the other database services. "A lot of the infrastructure powering everything else is running on Linux," Aboutoul said. "They're different flavors of Linux running all over the place," Aboutoul said. To run these services, Microsoft maintains its own kernel, Azure Linux, and in 2023 the company released its own version of Linux, Azure Linux. But Azure Linux is just a small portion of all the other flavors of Linux running on Azure, all of which Microsoft must work with to support. Overall, there are about 20,000 third-party Software as a Service (SaaS) packages in the Azure marketplace that rely on some Linux distribution. And when things go wrong, it is the Azure service engineers who get the help tickets. The company keeps a set of endorsed Linux distributions, which include Red Hat Enterprise Linux, Debian, Flatcar, Suse, Canonical, and Oracle Linux and CentOS (as managed by OpenLogic, not Red Hat). [...] Overall, the company gets about 1,000 images a month from these endorsed partners alone. Many of the distributions have multiple images (Suse has a regular one, and another one for high-performance computing, for instance).

"Anyone who is into gaming knows your graphics card is under strain trying to display modern graphics," writes longtime Slashdot reader smooth wombat. "This results in increased power usage, which is then turned into heat. Keeping your card cool is a must to get the best performance possible." "However, hardware tester Igor's Lab found that vendors for Nvidia RTX 40-series cards are using cheap, poorly applied thermal paste, which is leading to high temperatures and consequently, performance degradation over time. This penny-pinching has been confirmed by Nick Evanson at PC Gamer." From the report: I have four RTX 40-series cards in my office (RTX 4080 Super, 4070 Ti, and two 4070s) and all of them have quite high hotspots -- the highest temperature recorded by an individual thermal sensor in the die. In the case of the 4080 Super, it's around 11 C higher than the average temperature of the chip. I took it apart to apply some decent quality thermal paste and discovered a similar situation to that found by Igor's Lab. In the space of a few months, the factory-applied paste had separated and spread out, leaving just an oily film behind, and a few patches of the thermal compound itself. I checked the other cards and found that they were all in a similar state. Igor's Lab examined the thermal paste used on a brand-new RTX 4080 and found it to be quite thin in nature, due to large quantities of cheap silicone oil being used, along with zinc oxide filler. There was lots of ground aluminium oxide (the material that provides the actual thermal transfer) but it was quite coarse, leading to the paste separating quite easily. Removing the factory-installed paste from another RTX 4080 graphics card, Igor's Lab applied a more appropriate amount of a high-quality paste and discovered that it lowered the hotspot temperature by nearly 30 C.

An anonymous reader quotes a report from Ars Technica: The European Commission (EC) has finally taken action to block Meta's heavily criticized plan to charge a subscription fee to users who value privacy on its platforms. Surprisingly, this step wasn't taken under laws like the Digital Services Act (DSA), the Digital Markets Act (DMA), or the General Data Protection Regulation (GDPR). Instead, the EC announced Monday that Meta risked sanctions under EU consumer laws if it could not resolve key concerns about Meta's so-called "pay or consent" model. Meta's model is seemingly problematic, the commission said, because Meta "requested consumers overnight to either subscribe to use Facebook and Instagram against a fee or to consent to Meta's use of their personal data to be shown personalized ads, allowing Meta to make revenue out of it." Because users were given such short notice, they may have been "exposed to undue pressure to choose rapidly between the two models, fearing that they would instantly lose access to their accounts and their network of contacts," the EC said. To protect consumers, the EC joined national consumer protection authorities, sending a letter to Meta requiring the tech giant to propose solutions to resolve the commission's biggest concerns by September 1. That Meta's "pay or consent" model may be "misleading" is a top concern because it uses the term "free" for ad-based plans, even though Meta "can make revenue from using their personal data to show them personalized ads." It seems that while Meta does not consider giving away personal information to be a cost to users, the EC's commissioner for justice, Didier Reynders, apparently does. "Consumers must not be lured into believing that they would either pay and not be shown any ads anymore, or receive a service for free, when, instead, they would agree that the company used their personal data to make revenue with ads," Reynders said. "EU consumer protection law is clear in this respect. Traders must inform consumers upfront and in a fully transparent manner on how they use their personal data. This is a fundamental right that we will protect." Additionally, the EC is concerned that Meta users might be confused about how "to navigate through different screens in the Facebook/Instagram app or web-version and to click on hyperlinks directing them to different parts of the Terms of Service or Privacy Policy to find out how their preferences, personal data, and user-generated data will be used by Meta to show them personalized ads." They may also find Meta's "imprecise terms and language" confusing, such as Meta referring to "your info" instead of clearly referring to consumers' "personal data." A Meta spokesperson said in a statement: "Subscriptions as an alternative to advertising are a well-established business model across many industries. Subscription for no ads follows the direction of the highest court in Europe and we are confident it complies with European regulation."

Researchers have identified a zero-day exploit for the Telegram messaging app on Android devices that could have allowed attackers to send malicious payloads disguised as legitimate files. From a report: The exploit was built to abuse a vulnerability that Slovakia-based firm ESET dubbed EvilVideo. Telegram fixed the bug earlier this month in versions 10.14.5 and above after researchers reported it. Threat actors had about five weeks to exploit the zero-day before it was patched, but it's not clear if it was used in the wild, ESET said. ESET discovered the exploit on an underground forum in early June. It was sold for an unspecified price by a user with the username "Ancryno." In its post, the seller showed screenshots and a video of testing the exploit in a public Telegram channel. In unpatched versions of Telegram for Android, attackers could use the exploit to send malicious payloads via Telegram channels, groups and chats, making them appear as multimedia files. The exploit takes advantage of Telegram's default setting to automatically download media files. The option can be disabled manually, but in that case, the payload could still be installed on the device if a user tapped the download button in the top left corner of the shared file. If the user tried to play the "video," Telegram displayed a message that it was unable to play it and suggested using an external player. The hackers disguised a malicious app as this external player.

In an interview with The Verge's Nilay Patel, Rivian founder and CEO RJ Scaringe said the automaker has no plans to adopt Apple CarPlay in its vehicles. "We have a great relationship with Apple," he said. "As much as I love their products, there's a reason that ironically is very consistent with Apple ethos for us to want to control the ecosystem." CarPlay isn't "consistent with how we think about really creating a pure product experience," Scaringe said. From the report: One example given by Scaringe includes CarPlay's inability to "leverage other parts of the vehicle experience," which would require Rivian customers to leave the app in order to do things like open the vehicle's front trunk. "We've taken the view of the digital experience in the vehicle wants to feel consistent and holistically harmonious across every touchpoint," said Scaringe. Instead, the Rivian CEO says the company will eventually add CarPlay's most desirable features "but on an a la carte basis." Scaringe says that excluding CarPlay will allow the company to be more selective about features like routing and mapping charging points, noting that Rivian had acquired route planning app maker Iternio last year to facilitate that. "We recognize that it'll take us time to fully capture every feature that's in CarPlay, and hopefully, customers are seeing that. I think it often gets more noise than it deserves," Scaringe said in the interview. "The other thing beyond mapping that's coming is better integration with texting. We know that needs to come, and it's something that teams are actively working on."

An anonymous reader quotes a report from Reuters: Boeing-owned Wisk Aero expects its pilotless air-taxi to begin carrying passengers "later in the decade" as it works with the U.S. regulator to secure approvals, its CEO said on Monday, amid skepticism among industry analysts about certification timelines. Wisk is one of several electric vertical take-off and landing (eVTOL) aircraft makers that have emerged over the last few years with a promise to provide an environmentally-friendly mode of transport in congested cities. But the industry faces technological hurdles such as making batteries powerful enough for companies to make more trips on a single charge. They also need to convince regulators and the public that the aircraft are safe, a barrier that is higher when the aircraft is autonomous. Wisk is developing a four-seater autonomous aircraft that will have a range of 90 miles (145 km). "We are right now testing and producing the elements of this aircraft that we will hope to fly around the end of this year," CEO Brian Yutko told reporters at the Farnborough Airshow. Wisk's strategy is a departure from other major air-taxi makers, which are developing models that will require a pilot to fly the aircraft. The company has said operators of its aircraft will save on pilot costs. But industry experts at Bain say a full autonomous passenger flight is not expected before the late 2030s and pilotless aircraft will face competition from autonomous vehicles on the road. "Maximizing passenger occupancy and avoiding return trips with empty aircraft will be crucial for operator profitability," said Mattia Celli, one of the authors of the Bain report.

In a blog post today, Google said it has an "updated approach" that won't involve "deprecating third-party cookies" in Chrome. Instead, it's introducing "a new experience in Chrome that lets people make an informed choice that applies across their web browsing," which they'd be able to adjust at any time. Digiday reports: Google executives are already discussing this pivot with regulators including the U.K.'s Competition and Markets Authority (CMA) and Information Commissioner's Office (ICO) and plan to do the same with the industry soon. For now, details on what this actually means remain light. And as for a timeline, Google seems to have learned its lesson from the numerous delays to its cookie-killing plans -- there isn't one. "As this moves forward, it remains important for developers to have privacy-preserving alternatives," Anthony Chavez, vp of the Privacy Sandbox, said in the blog post. "We'll continue to make the Privacy Sandbox APIs available and invest in them to further improve privacy and utility." For those who have poured time and effort into third-party cookie alternatives, fear not: Google will keep the APIs in the Sandbox. Your work isn't going to waste. In fact, the plan is to continue to invest in them, continued Chavez, to further improve "privacy and utility." Plus, additional privacy controls, like the recently announced IP Protection (i.e. IP masking for privacy protection) in Chrome's Incognito mode, will be added to the Sandbox. "We developed the Privacy Sandbox with the goal of finding innovative solutions that meaningfully improve online privacy while preserving an ad-supported internet that supports a vibrant ecosystem of publishers, connects businesses with customers, and offers all of us free access to a wide range of content," Chavez wrote in the blog post. Or, to put it another way, the Sandbox isn't going anywhere anytime soon.

Something is pumping out large amounts of oxygen at the bottom of the Pacific Ocean, at depths where a total lack of sunlight makes photosynthesis impossible. Nature: The phenomenon was discovered in a region strewn with ancient, plum-sized formations called polymetallic nodules, which could play a part in the oxygen production by catalysing the splitting of water molecules, researchers suspect. The findings are published in Nature Geoscience. "We have another source of oxygen on the planet, other than photosynthesis," says study co-author Andrew Sweetman, a sea-floor ecologist at the Scottish Association for Marine Science in Oban, UK -- although the mechanism behind this oxygen production remains a mystery. The findings could also have implications for understanding how life began, he says, as well as for the possible impact of deep-sea mining in the region. The observation is "fascinating," says Donald Canfield, a biogeochemist at the University of Southern Denmark in Odense. "But I find it frustrating, because it raises a lot of questions and not very many answers." Sweetman and his collaborators first noticed something amiss during field work in 2013. The researchers were studying sea-floor ecosystems in the Clarion-Clipperton Zone, an area between Hawaii and Mexico that is larger than India and a potential target for the mining of metal-rich nodules. During such expeditions, the team releases a module that sinks to the sea floor to perform automated experiments. Once there, the module drives cylindrical chambers down to close off small sections of the sea floor -- together with some seawater -- and create "an enclosed microcosm of the seafloor," the authors write. The lander then measures how the concentration of oxygen in the confined seawater changes over periods of up to several days. Without any photosynthetic organisms releasing oxygen into the water, and with any other organisms consuming the gas, oxygen concentrations inside the chambers should slowly fall. Sweetman has seen that happen in studies he has conducted in areas of the Southern, Arctic and Indian oceans, and in the Atlantic. Around the world, sea-floor ecosystems owe their existence to oxygen carried by currents from the surface, and would quickly die if cut off. (Most of that oxygen originates in the North Atlantic and is carried to deep oceans around the world by a 'global conveyor belt.')

Verizon reported a significant loss of wireless subscribers in the second quarter, with its consumer business shedding 624,000 prepaid customers, largely due to the expiration of the federal Affordable Connectivity Program in May. The telecom giant attributed over half of these losses to the end of the COVID-era internet subsidy that had previously supported 23 million low-income households across the United States. Despite the subscriber exodus, Verizon managed to add 148,000 net monthly bill-paying wireless phone subscribers during the period.

Luxury carmaker Porsche expects the transition to electric vehicles to take longer than it thought, it said on Monday, having previously said its aim was for 80% of sales to be all-electric by 2030. From a report: It has now watered down that goal by tying it explicitly to customer demand and developments in the electromobility sector, saying in a statement only that it could now deliver on the 80% target if those factors warrant it. "The transition to electric cars is taking longer than we thought five years ago," Porsche said in a statement. "Our product strategy is set up such that we could deliver over 80% of our vehicles as all electric in 2030 - dependent on customer demand and the development of electromobility."

An amateur photographer has documented his experience with at-home color film development and digitization. The process, initially undertaken for cost savings, involves a complex setup including a changing bag, developing tank, chemicals, and a DSLR scanning system, the author argues. Key challenges reported include film loading in darkness and achieving consistent image quality. Despite mixed results, the hobbyist -- Jason Koebler, an editor of 404 Media, a new publication that we have linked to quite a few times in recent months -- nonetheless cites satisfaction with the artistic and analog aspects of the process. He concludes: I have obviously (obviously!) not saved any money yet by doing this myself at home. I have spent many hundreds of dollars to develop about 20 rolls of film at home, and have achieved results that I am both amazed by and also frustrated with. The amazement comes from the fact that any of this actually works at all, and the knowledge that I am trying my best and having fun. The frustration comes from the blurry photos. It's all part of the process, I guess.

Intel continues to grapple with the mystery surrounding crashes in its latest 13th- and 14th-gen Core desktop processors, but it's refuting claims that the issue extends to its mobile chips. From a report: Matthew Cassells, the founder of Alderon Games and developer of Path of Titans, claimed on Reddit that the company had noted crashes on Intel's mobile processors. "Yes we have several laptops that have failed with the same crashes," he wrote. "It's just slightly more rare then [sic] the desktop CPU faults." Previously, Alderon had issued a statement blaming "thousands of crashes," as noted by its own crash reports on the Intel CPUs. It also claimed it would switch its server infrastructure to chips made by AMD. Intel's problem with its latest Core chips has persisted since January, but simmered for months while developers began pointing fingers and PC makers started working on solutions. To date, the most bulletproof solution has been simply to swap out an affected part for a replacement, which Intel has been willing to do. Intel has also issued guidance as to what power-profile settings users and board makers should use while it works to solve the problem. An Intel representative said Friday via e-mail that Intel still remains in the dark about the root cause of the issue. However, Intel claims that its mobile processors aren't being affected.

The United States has claimed victory at the International Mathematical Olympiad in Chiang Mai, Thailand, marking its first win in over two decades. The competition, which pitted top-ranked high school math students from more than 100 countries against each other, saw the U.S. team emerge triumphant after two days of intense problem-solving. NPR adds: The U.S. team last won the Olympiad in 1994. Reports in recent years have raised concerns that American math students are falling behind those in the rest of the world. But, Po-Shen Loh, a professor at Carnegie Mellon University and head coach for Team USA, says, "At least in this case with the Olympiads, we've been able to prove that our top Americans are certainly at the level of the top people from the other countries."
