Pilot Union Urges FAA To Reject Rainmaker's Drone Cloud-Seeding Plan

Par :BeauHD
13 septembre 2025 à 13:00
An anonymous reader quotes a report from TechCrunch: Rainmaker Technology's bid to deploy cloud-seeding flares on small drones is being met by resistance from the airline pilots union, which has urged the Federal Aviation Administration to consider denying the startup's request unless it meets stricter safety guidelines. The FAA's decision will signal how the regulator views weather modification by unmanned aerial systems going forward. Rainmaker's bet on small drones hangs in the balance. The Air Line Pilots Association (ALPA) told the FAA that Rainmaker's petition "fails to demonstrate an equivalent level of safety" and poses "an extreme safety risk." Rainmaker is seeking an exemption from rules that bar small drones from carrying hazardous materials. The startup filed in July, and the FAA has yet to rule. Instead, it issued a follow-up request for information, pressing for specifics on operations and safety. In its filing, Rainmaker proposed using two flare types, one "burn-in-place" and the other ejectable, on its Elijah quadcopter, to disperse particles that stimulate precipitation. Elijah has a maximum altitude of 15,000 feet MSL (measured from sea level), which sits inside controlled airspace where commercial airliners routinely fly. Drones need permission from Air Traffic Control to fly inside this bubble. Rainmaker's petition says it will operate in Class G (uncontrolled) airspace unless otherwise authorized. ALPA notes the filing doesn't clearly state where flights would occur or what altitudes would be used. Rainmaker and ALPA did not reply to TechCrunch's requests for comment. The union also objects to the flares themselves, citing concerns about foreign object debris and fire safety. ALPA points out that the petition does not include trajectory modeling of the ejectable casings or analysis on the environmental impacts of chemical agents. However, Rainmaker says the flights will occur over rural areas and over properties owned by private landlords "with whom Rainmaker has developed close working relationships." [...] What happens next hinges on whether the FAA thinks those mitigations are sufficient. However it's decided, the agency's response will likely set the tone for novel cloud-seeding approaches.

E-Bike Injuries Are a Massive Burden, Say Surgeons

Par :BeauHD
13 septembre 2025 à 10:00
Surgeons in London report a surge in severe e-bike-related injuries, putting major strain on NHS trauma units. The BBC mentions a couple e-bike accidents overheard at the Royal London Hospital in Whitechapel. "A 32-year-old, fit and well student... a couple of days ago he fell off an e-bike sustaining a closed left tibial plateau fracture." Another case involved a little girl named Frida: "Six-year-old girl, she was hit by an electric bike, she has a closed tib/fib fracture." From the report: Surgeon Jaison Patel is seeing more and more cases like this. "It's a massive burden on our department and I'm sure it's the same across the whole of London," he tells us. "If we can reduce the number of patients coming in with these sorts of injuries it would be great for the patients obviously, but also takes massive pressure off us in the NHS." Jaison deals with lower limb injuries. Just along the corridor his colleague Nick Aresti does the upper limbs. Nick explains that he is a cyclist himself, and it's something he encourages people to do for the benefit of their health. But, he has real concerns about e-bikes, and says: "What we've noticed with e-bikes is that the speed in which people are coming off is much higher and as a result, the injuries are much worse." He shows us X-rays of someone who has broken their collarbone. He explains that with e-bikes, the injuries they're seeing are much more severe, and as such, people are "struggling to get back to normality." Nick and Jaison both agree it's something they're seeing increasingly more of as time goes by, and they think the industry needs better regulation. "We should do something about it, I don't think we can let this carry on," Jaison says. Over recent days of course, thousands of Londoners have taken to e-bikes to help beat the strikes. For many it has been an essential way to get about. Currently, anyone aged 14 or over can legally ride an e-bike. The power output of an e-bike's motor should be capped at 250 watts, and the motor should not be capable of propelling the bike any faster than 15.5mph (25kph), according to government rules. London's Walking and Cycling Commissioner Will Norman says the rules need changing and says better regulation of the rentable electric bikes could be on the way. "We need to ensure that the vehicles are safe, that there's parking, they're not scattered all over the place, and that the batteries are safe," he says. "I'm really delighted that the government has now indicated in its English Devolution Bill that London and other cities across the UK will be getting more powers so again we can start regulating that, to ensure that they're safe for people to use and operate while they get around". The bill is currently going through parliament, and as yet there is no date for when it will be passed. Duncan Dollimore, head of campaigns at Cycling UK, who are members of the Electric Bike Alliance, argues against the regulation of e-bike usage. "The cost of inactivity-related health issues to the NHS each year is 7.4 billion pounds, and people cycling saves them 1 billion pounds. We have seen a slight rise in the number of incidents involving hired e-bikes in London, but the health benefits of people cycling outweigh the risks by around 20 to one."

Synthetic Magnetic Fields Steer Light On a Chip For Faster Communications

Par :BeauHD
13 septembre 2025 à 07:00
Researchers in China have created synthetic magnetic fields within silicon photonic crystals, allowing them to steer and control light on a chip with unprecedented precision. "Beyond immediate applications, the work opens new avenues for studying quantum-inspired phenomena with light," reports Phys.org. "The ability to impose artificial gauge fields in photonic systems could enable devices for optical computing, quantum information, and advanced communication technologies." Slashdot reader alternative_right shares an excerpt from the report: The team achieved this by systematically altering the symmetry of tiny repeating units in silicon photonic crystals. Adjusting the degree of local asymmetry at each point allowed them to 'design' pseudomagnetic fields with tailored spatial patterns, without breaking fundamental time-reversal symmetry. Both theoretical analysis and experiments confirmed that these engineered fields can guide and manipulate light in versatile ways. To demonstrate practical applications, the researchers built two devices commonly used in integrated optics. One was a compact S-shaped waveguide bend that transmitted light with less than 1.83 decibels of signal loss. The other was a power splitter that divided light into two equal paths with low excess loss and minimal imbalance. In a final test, the devices successfully transmitted a high-speed data stream at 140 gigabits per second using a standard telecommunications modulation format, showing that the technique is compatible with existing optical communication systems. The research has been published in Advanced Photonics.

Proton Mail Suspended Journalist Accounts At Request of Cybersecurity Agency

Par :BeauHD
13 septembre 2025 à 03:30
An anonymous reader quotes a report from The Intercept: The company behind the Proton Mail email service, Proton, describes itself as a "neutral and safe haven for your personal data, committed to defending your freedom." But last month, Proton disabled email accounts belonging to journalists reporting on security breaches of various South Korean government computer systems following a complaint by an unspecified cybersecurity agency. After a public outcry, and multiple weeks, the journalists' accounts were eventually reinstated -- but the reporters and editors involved still want answers on how and why Proton decided to shut down the accounts in the first place. Martin Shelton, deputy director of digital security at the Freedom of the Press Foundation, highlighted that numerous newsrooms use Proton's services as alternatives to something like Gmail "specifically to avoid situations like this," pointing out that "While it's good to see that Proton is reconsidering account suspensions, journalists are among the users who need these and similar tools most." Newsrooms like The Intercept, the Boston Globe, and the Tampa Bay Times all rely on Proton Mail for emailed tip submissions. Shelton noted that perhaps Proton should "prioritize responding to journalists about account suspensions privately, rather than when they go viral." On Reddit, Proton's official account stated that "Proton did not knowingly block journalists' email accounts" and that the "situation has unfortunately been blown out of proportion." The two journalists whose accounts were disabled were working on an article published in the August issue of the long-running hacker zine Phrack. The story described how a sophisticated hacking operation -- what's known in cybersecurity parlance as an APT, or advanced persistent threat -- had wormed its way into a number of South Korean computer networks, including those of the Ministry of Foreign Affairs and the military Defense Counterintelligence Command, or DCC. The journalists, who published their story under the names Saber and cyb0rg, describe the hack as being consistent with the work of Kimsuky, a notorious North Korean state-backed APT sanctioned by the U.S. Treasury Department in 2023. As they pieced the story together, emails viewed by The Intercept show that the authors followed cybersecurity best practices and conducted what's known as responsible disclosure: notifying affected parties that a vulnerability has been discovered in their systems prior to publicizing the incident. Phrack said the account suspensions created a "real impact to the author. The author was unable to answer media requests about the article." Phrack noted that the co-authors were already working with affected South Korean organizations on responsible disclosure and system fixes. "All this was denied and ruined by Proton," Phrack stated. Phrack editors said that the incident leaves them "concerned what this means to other whistleblowers or journalists. The community needs assurance that Proton does not disable accounts unless Proton has a court order or the crime (or ToS violation) is apparent."

US EV Sales Smash Records In August

Par :BeauHD
13 septembre 2025 à 01:50
US EV sales hit a record 146,332 in August, grabbing nearly 10% of all new car sales, according to Kelley Blue Book. That's the highest yet and up from 9.1% in July. Electrek reports: With the federal EV tax credit set to expire on September 30, analysts say Q3 2025 is shaping up to be the strongest quarter for EV sales in US history. The current record holder is Q4 2024, when 365,824 EVs were sold. Prices ticked higher, too. The average transaction price (ATP) for an EV in August was $57,245, 3.1% more than July's revised lower ATP of $55,562. Year-over-year, though, EV prices were basically flat, down just 0.1%. The wave of EV sales also helped push up the overall market's ATP. Incentives, while not as high as July's record, remained hefty. EV buyers received discounts averaging over $9,000 in August, equal to 16% of ATP. That's more than double the incentive rate in the overall auto market and up from 13.6% a year ago. A separate report from Rho Motion found that global EV sales surged 25% in 2025, led by strong growth in Europe and China. "That amounts to 12.5 million EVs, although the data combines both battery EVs and plug-in hybrid EVs for the total," reports Ars Technica. As for North America? "EV sales are still growing but barely -- up just 6 percent between January and August 2025 compared to the same time period in 2024."

Newfoundland's 10-Year Education Report Calling For Ethical AI Use Contains Over 15 Fake Sources

Par :BeauHD
13 septembre 2025 à 01:10
Newfoundland and Labrador's 10-year Education Accord report (PDF) intended to guide school reform has been found to contain at least 15 fabricated citations, including references to non-existent films and journals. Academics suggest the fake sources may have been generated by AI. "There are sources in this report that I cannot find in the MUN Library, in the other libraries I subscribe to, in Google searches. Whether that's AI, I don't know, but fabricating sources is a telltale sign of artificial intelligence," said Aaron Tucker, an assistant professor at Memorial whose current research focuses on the history of AI in Canada. "The fabrication of sources at least begs the question: did this come from generative AI?" CBC News reports: In one case, the report references a 2008 movie from the National Film Board called Schoolyard Games. The film doesn't exist, according to a spokesperson for the board. But the exact citation used in the report can be found in a University of Victoria style guide -- a document that clearly lists fake references designed as templates for researchers writing a bibliography. "Many citations in this guide are fictitious," reads the first page of the document. "Errors happen. Made-up citations are a totally different thing where you essentially demolish the trustworthiness of the material," said Josh Lepawsky, the former president of the Memorial University Faculty Association who resigned from the report's advisory board last January, citing a "deeply flawed process" leading to "top-down" recommendations. The 418-page Education Accord NL report took 18 months to complete and was unveiled Aug. 28 by its co-chairs Anne Burke and Karen Goodnough, both professors at Memorial's Faculty of Education. The pair released the report alongside Education Minister Bernard Davis. "We are investigating and checking references, so I cannot respond to this at the moment," wrote Goodnough in an email declining an interview Thursday. In a statement, the Department of Education and Early Childhood Development said it was aware of a "small number of potential errors in citations" in the report. "We understand that these issues are being addressed, and that the online report will be updated in the coming days to rectify any errors."

Employee Who Leaked 'Spider-Man' Blu-ray Sentenced to Nearly 5 Years Prison

Par :BeauHD
13 septembre 2025 à 00:30
A former Memphis disc manufacturing employee has been sentenced to nearly five years in prison after stealing pre-release Blu-rays from his employer and leaking them online. While he received 21 months for copyright infringement, a concurrent firearm charge extended his total prison term to 57 months. TorrentFreak reports: In February, the U.S. Department of Justice indicted 37-year-old Steven Hale from Tennessee, a former employee of a disc manufacturing and distribution company in Memphis. While working at the unnamed company between 2021 and 2022, Hale allegedly stole numerous "pre-release" DVD and Blu-ray discs from his employer. These stolen discs contained many high-profile movie titles including "Spider-Man: No Way Home." In addition to the copyright infringement charge, Hale was also indicted for a firearm offense. When raiding his premises, law enforcement found a gun in a car that was registered in his name, which, for a felon, is a separate criminal offense. Hale was sentenced at a federal court in Memphis yesterday, where Chief Judge Sheryl H. Lipman handed down a 57-month prison term, exactly in line with the U.S. government's recommendation. Two separate sentences will be served concurrently. Hale received 21 months for the theft and distribution of hundreds of pre-release movie discs. A longer sentence of 57 months was handed down for the firearm charge, which ultimately defines the total prison term. Judge Lipman also granted several requests by the defense. The court recommended that Hale be housed in a facility as close to Memphis as possible so he can be near his family. In addition, the defendant will be allowed to remain on bond and self-surrender to prison at a later date. The 21-month sentence for the copyright infringement charge is substantially lower than the maximum of 60 months. This is in part the result of a guilty plea the defendant signed in May. After accepting responsibility, the prosecution agreed to drop other charges and recommend a sentence at the low end of the guideline range. Hale entered his guilty plea to Count Two of the indictment. The charge relates to his distribution of ten or more copies of copyrighted works, including pre-release movies, for commercial advantage and private financial gain. This includes the pre-release 'Spider-Man: No Way Home' disc, which is likely the source of the public leak.

From Discord To Bitchat, Tech At the Heart of Nepal Protests

Par :BeauHD
12 septembre 2025 à 23:50
An anonymous reader quotes a report from France24: Fueled in part by anger over flashy lifestyles flaunted by elites, young anti-corruption demonstrators mainly in their 20s rallied on Monday. The loose grouping, largely viewed as members of "Gen Z", flooded the capital Kathmandu to demand an end to a ban on Facebook, YouTube and other popular sites. The rallies ended in chaos and tragedy, with at least 19 protesters killed in a police crackdown on Monday. The apps were restored, but protests widened in anger. On Tuesday, other Nepalis joined the crowds. Parliament was set ablaze, KP Sharma Oli resigned as prime minister, and the army took charge of the streets. Now, many activists are taking to the US group-chat app Discord to talk over their next steps. One server with more than 145,000 members has hosted feverish debate about who could be an interim leader, with many pushing 73-year-old former chief justice Sushila Karki. It is just one example of how social media has driven demands for change. [...] More than half of Nepal's 30 million people are online, according to the World Bank. Days before the protests, many had rushed to VPN services — or virtual private networks — to evade blocks on platforms. Fears of a wider internet shutdown also drove a surge in downloads for Bluetooth messaging app Bitchat, created by tech billionaire Jack Dorsey. "Tech played... an almost decisive role," journalist Pranaya Rana told AFP. "The whole thing started with young people posting on social media about corruption, and the lavish lives that the children of political leaders were leading." Hashtags such as #NepoKids, short for nepotism, compared the designer clothing and luxury holidays shown off in their Instagram posts to the difficulties faced by ordinary Nepalis. One post liked 13,000 times accused politicians' children of "living like millionaires," asking: "Where is the tax money going?" "NepoKids was trending all the time," including in rural areas where Facebook is popular, said rights activist Sanjib Chaudhary. "This fuelled the fire" of anger that "has been growing for a long time," he said. [...] Chaudhary said the government "seriously underestimated the power of social media." Nepal's first female prime minister was sworn in Friday as interim leader after protesters held an informal vote on Discord. "Former chief justice Sushila Karki, 73, was the unlikely choice of the 'Gen Z' protesters behind the movement that started out as a social media demonstration against the lavish lifestyles of 'Nepo Kids' but spilled out onto the streets and into the deadliest social unrest Nepal has seen in years," reports CNN World. "Karki has spent much of her career within the very establishment the youth are protesting against, yet her reputation as a fearless and incorruptible jurist has appealed to many young people in the country of 30 million."

Intel Talent Bleed Continues

Par :BeauHD
12 septembre 2025 à 23:10
Intel's long-time Xeon chief architect Ronak Singhal is leaving the company after nearly 30 years, marking yet another high-profile departure amid Intel's leadership churn and intensifying competition from AMD and Arm-based cloud CPUs. The Register reports: The Carnegie Mellon alum holds degrees in electrical and computer engineering, along with at least 30 patents involving CPUs. Singhal joined Intel in 1997 after spending the previous summer as an intern at Cyrix. After a year in Intel's Rotation Engineers Program, he spent the remainder of his tenure helping to develop some of the chipmaker's most consequential and, at times, controversial processors. Most notably, Singhal oversaw the core development of Intel's 22nm Haswell and 14nm Broadwell processor architectures. His innovations aren't limited to the datacenter either, with his architectural contributions playing a significant role in the success of Intel's Core and Atom processor families as well. [...] Singhal is only the latest Xeon lead to jump ship since the start of the year. In January, Sailesh Kottapalli, another senior fellow, left for Qualcomm barely a month after former CEO Pat Gelsinger's unceremonious "retirement." Even before Gelsinger's eviction, Intel's datacenter group has been something of a revolving door. Last summer Singhal's long-time colleague Lisa Spelman departed the company, eventually landing a spot as CEO of HPC interconnect vendor Cornelis Networks. Her replacement, Ryan Tabrah, lasted seven months in the role, about half as long as Intel datacenter boss Justin Hotard, who defected for the forests of Finland to lead Nokia as its new President and CEO back in April. In fact, the churn now extends all the way to the top. On Monday, Intel announced its CEO of Products, Michelle Johnston Holthaus, would be leaving the business. The move is part of a broader executive shakeup that will see former Arm engineer Kevork Kechichian take over as head of Intel's datacenter engineering group. Jim Johnson, meanwhile, will take over as head of the chipmaker's client computing group while Srinivasan (Srini) Iyengar will head up a new central engineering division.

Microsoft, OpenAI Reach Non-Binding Deal To Allow OpenAI To Restructure

Par :BeauHD
12 septembre 2025 à 22:30
Microsoft and OpenAI have signed a non-binding deal to restructure their partnership, paving the way for OpenAI to shift into a conventional for-profit model and potentially go public. Reuters reports: Details on the new commercial arrangements were not disclosed, but the companies said they were working to finalize terms of a definitive agreement. [...] Microsoft invested $1 billion in OpenAI in 2019 and another $10 billion at the beginning of 2023. Under their previous agreement, Microsoft had exclusive rights to sell OpenAI's software tools through its Azure cloud computing platform and had preferred access to the startup's technology. Microsoft was once designated as OpenAI's sole compute provider, though it lessened its grip this year to allow OpenAI to pursue its own data center project, Stargate, including signing $300 billion worth of long-term contracts with Oracle, as well as another cloud deal with Google. As OpenAI's revenue grows into the billions, it is seeking a more conventional corporate structure and partnerships with additional cloud providers to expand sales and secure the computing capacity needed to meet demand. Microsoft, meanwhile, wants continued access to OpenAI's technology even if OpenAI declares its models have reached humanlike intelligence - a milestone that would end the current partnership under existing terms. OpenAI said under current terms, its nonprofit arm will receive more than $100 billion -- about 20% of the $500 billion valuation it is seeking in private markets -- making it one of the most well-funded nonprofits, according to a memo from Bret Taylor, chairman of OpenAI's current nonprofit board. The companies did not disclose how much of OpenAI Microsoft will own, nor whether Microsoft will retain exclusive access to OpenAI's latest models and technology. Regulatory hurdles remain for OpenAI, as attorneys general in California and Delaware need to approve OpenAI's new structure. The company hopes to complete the conversion by year's end, or risk losing billions in funding tied to that timeline.

Spotify Peeved After 10,000 Users Sold Data To Build AI Tools

Par :BeauHD
12 septembre 2025 à 21:50
An anonymous reader quotes a report from Ars Technica: For millions of Spotify users, the "Wrapped" feature -- which crunches the numbers on their annual listening habits -- is a highlight of every year's end, ever since it debuted in 2015. NPR once broke down exactly why our brains find the feature so "irresistible," while Cosmopolitan last year declared that sharing Wrapped screenshots of top artists and songs had by now become "the ultimate status symbol" for tens of millions of music fans. It's no surprise then that, after a decade, some Spotify users who are especially eager to see Wrapped evolve are no longer willing to wait to see if Spotify will ever deliver the more creative streaming insights they crave. With the help of AI, these users expect that their data can be more quickly analyzed to potentially uncover overlooked or never-considered patterns that could offer even more insights into what their listening habits say about them. Imagine, for example, accessing a music recap that encapsulates a user's full listening history -- not just their top songs and artists. With that unlocked, users could track emotional patterns, analyzing how their music tastes reflected their moods over time and perhaps helping them adjust their listening habits to better cope with stress or major life events. And for users particularly intrigued by their own data, there's even the potential to use AI to cross data streams from different platforms and perhaps understand even more about how their music choices impact their lives and tastes more broadly. Likely just as appealing as gleaning deeper personal insights, though, users could also potentially build AI tools to compare listening habits with their friends. That could lead to nearly endless fun for the most invested music fans, where AI could be tapped to assess all kinds of random data points, like whose breakup playlists are more intense or who really spends the most time listening to a shared favorite artist. In pursuit of supporting developers offering novel insights like these, more than 18,000 Spotify users have joined "Unwrapped," a collective launched in February that allows them to pool and monetize their data. Voting as a group through the decentralized data platform Vana -- which Wired profiled earlier this year -- these users can elect to sell their dataset to developers who are building AI tools offering fresh ways for users to analyze streaming data in ways that Spotify likely couldn't or wouldn't. In June, the group made its first sale, with 99.5 percent of members voting yes. Vana co-founder Anna Kazlauskas told Ars that the collective -- at the time about 10,000 members strong -- sold a "small portion" of its data (users' artist preferences) for $55,000 to Solo AI. While each Spotify user only earned about $5 in cryptocurrency tokens -- which Kazlauskas suggested was not "ideal," wishing the users had earned about "a hundred times" more -- she said the deal was "meaningful" in showing Spotify users that their data "is actually worth something." Spotify responded to the collective by citing both trademark and policy violations. The company sent a letter to Unwrapped developers, warning that the project's name may infringe on Spotify's Wrapped branding, and that Unwrapped breaches developer terms. Specifically, Spotify objects to Unwrapped's use of platform data for AI/ML training and facilitating user data sales. "Spotify honors our users' privacy rights, including the right of portability," Spotify's spokesperson said. "All of our users can receive a copy of their personal data to use as they see fit. That said, UnwrappedData.org is in violation of our Developer Terms which prohibit the collection, aggregation, and sale of Spotify user data to third parties." Unwrapped says it plans to defend users' right to "access, control, and benefit from their own data," while providing reassurances that it will "respect Spotify's position as a global music leader."

Scientists Link Hundreds of Severe Heat Waves To Fossil Fuel Producers' Pollution

Par :BeauHD
12 septembre 2025 à 10:00
A new study published in Nature links more than 200 severe heat waves directly to greenhouse gas pollution from major fossil fuel producers like ExxonMobil, Chevron, and BP. Researchers found that up to a quarter of these heat waves would have been virtually impossible without emissions from oil, coal, and cement companies. NPR reports: The new study, published Wednesday in the journal Nature, found that 213 heat waves were substantially more likely and intense because of the activity of major fossil fuel producers, also called carbon majors. They include oil, coal and cement companies, as well as some countries. The scientists found as much as a quarter of the heat waves would be "virtually impossible" without the climate pollution from major fossil fuel producers. Some individual fossil fuel companies, such as ExxonMobil, Chevron and BP, had emissions high enough to cause some of the more extreme heat waves, the research found. For the new study, the scientists looked at something called the disaster database, a global list of disasters maintained by university researchers, to identify heat waves "with significant casualties, economic losses and calls for international assistance. The scientists then used historical reconstructions and statistical models to see how human-caused global warming made each heat wave more likely and more intense. Then, to examine the link to major fossil fuel producers, the researchers relied on the Carbon Majors Database to understand the emissions of major oil, gas, coal and cement producers. "We ran a climate model to reconstruct the historical period, and then we ran it again but without the emissions of a specific carbon major, thus deducing its contribution to global warming," Yann Quilcaille, climate scientist at ETH Zurich and lead author of the study, says in an email. While some of the contributions to heat waves came from larger well-known fossil fuel companies, the study found that some smaller, lesser-known fossil fuel companies are producing enough greenhouse gas emissions to cause heat waves too, Quilcaille says.

Gravitational Waves Finally Prove Stephen Hawking's Black Hole Theorem

Par :BeauHD
12 septembre 2025 à 07:00
Physicists have confirmed Stephen Hawking's 1971 black hole area theorem with near-absolute certainty, thanks to gravitational waves from an exceptionally loud black hole collision detected by upgraded LIGO instruments. New Scientist reports: Hawking proposed his black hole area theorem in 1971, which states that when two black holes merge, the resulting black hole's event horizon -- the boundary beyond which not even light can escape the clutches of a black hole -- cannot have an area smaller than the sum of the two original black holes. The theorem echoes the second law of thermodynamics, which states that the entropy, or disorder within an object, never decreases. Black hole mergers warp the fabric of the universe, producing tiny fluctuations in space-time known as gravitational waves, which cross the universe at the speed of light. Five gravitational wave observatories on Earth hunt for waves 10,000 times smaller than the nucleus of an atom. They include the two US-based detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) plus the Virgo detector in Italy, KAGRA in Japan and GEO600 in Germany, operated by an international collaboration known as LIGO-Virgo-KAGRA (LVK). The recent collision, named GW250114, was almost identical to the one that created the first gravitational waves ever observed in 2015. Both involved black holes with masses between 30 and 40 times the mass of our sun and took place about 1.3 billion light years away. This time, the upgraded LIGO detectors had three times the sensitivity they had in 2015, so they were able to capture waves emanating from the collision in unprecedented detail. This allowed researchers to verify Hawking's theorem by calculating that the area of the event horizon was indeed larger after the merger. The findings have been published in the journal Physical Review Letters.

AI Use At Large Companies Is In Decline, Census Bureau Says

Par :BeauHD
12 septembre 2025 à 03:30
An anonymous reader quotes a report from Gizmodo: [D]espite the AI industry's attempts to make itself seem omnipresent, a new report this week shows that adoption at large U.S. companies has declined. The report comes from the Census Bureau and shows that the rate of AI adoption by large companies -- that is, firms with over 250 employees -- has been declining slightly in recent weeks. The report is based on a biweekly survey, dubbed Business Trends and Outlook (or BTOS), of some 1.2 million U.S. firms. The survey, which asks businesses about their use of AI tools, such as machine learning and agents, found that -- between June and now -- the rate of adoption had declined from 14 to 12 percent. Futurism notes that this is the largest drop-off in the adoption rate since the survey first began in 2023, although the survey also showed a slight increase in AI use among smaller companies. The moderate drop off comes after the rate of adoption had climbed precipitously over the last few years. When the survey first began, in September of 2023, the AI adoption rate hovered around 3.7 percent (PDF), while the adoption rate in December 2024 was around 5.7 percent. In the second quarter of this year, the rate also rose significantly, climbing from 7.4 percent to 9.2. The new drop-off in reported usage comes not long after another study, this one published by MIT, found that a vast majority of corporate AI pilot programs had failed to produce any material benefit to the companies involved.

Microsoft has eliminated the one-time fee for publishing apps on its Windows Store. According to The Verge, "Individual developers in nearly 200 countries can now sign up to publish apps on the Microsoft Store with just a personal Microsoft account, and no more one-time fees." From the report: Microsoft started cutting its $19 one-time fee to publish apps to its Windows store in June in certain markets, and it's now essentially removing this fee for all developers worldwide. Apple still charges an annual $99 fee to developers, and Google charges a one-time registration fee of $25. "Developers will no longer need a credit card to get started, removing a key point of friction that has affected many creators around the world," explains Chetna Das, senior product manager at Microsoft. "By eliminating these one-time fees, Microsoft is creating a more inclusive and accessible platform that empowers more developers to innovate, share and thrive on the Windows ecosystem." [...] The Microsoft Store is now used by more than 250 million monthly active users, according to Microsoft. Microsoft is now encouraging more developers to make use of the store, where they can publish a variety of Win32, UWP, PWA, .NET, MAUI, or Electron apps. Developers can even use their own in-app commerce system to keep 100 percent of their revenues on non-gaming apps.

'No Tax On Tips' Includes Digital Creators, Too

"President Trump's One Big Beautiful Bill Act may have quietly changed the economics of the creator economy," reports the Hollywood Reporter. The Treasury Department has ruled this past week that digital creators, including podcasters, influencers, and streamers, qualify for the U.S. "no tax on tips" policy, allowing them to deduct tipped income up to $25,000. From the report: The change could cause digital creators to rethink how they seek income. Platforms like TikTok, YouTube, Twitch and Snapchat all offer a variety of ways for creators to generate income, be it a share of advertising revenue or creator funding programs, or options to launch subscription tiers for their channels or profiles. But they also give creators the option to turn on tips or gifts. If revenue from user tips or gifts is eligible, while recurring subscription revenue is not, it could shift how streamers, podcasters or influencers ask their followers to support them. To be sure, there are limitations: The tax deduction is capped at $25,000 per year, and it begins to phase out at $150,000 in income for single filers and $300,000 for married joint filers. The act also provides that tips do not qualify for the deduction if they are received "in the course of certain specified trades or businesses -- including the fields of health, performing arts, and athletics," Treasury says, further limiting the deduction opportunity for some in entertainment-adjacent lines of work. But by making influencers, Twitch streamers and podcasters eligible, the administration has nonetheless changed the incentive structure for digital creators, and the ramifications could be felt across the creator economy in the name of tax efficiency (Don't be surprised if users are asked to like, subscribe, and tip). Platforms may also develop more ways to more prominently feature tips and gifts, pushing creators to add more opportunities for that income. But the inclusion of digital creators is also a recognition of how the power dynamics have shifted in media.

Amid yesterday's news of Oracle's soaring stock, which propelled founder Larry Ellison to the top of the world's richest list, the Wall Street Journal reported that the cloud giant and OpenAI have struck one of the largest cloud contracts ever signed. Under the deal, OpenAI will purchase $300 billion worth of compute power from Oracle over roughly five years, with purchases beginning in 2027. "This move away from Microsoft was timed with OpenAI's involvement with the Stargate Project, in which OpenAI, SoftBank, and Oracle have committed to invest $500 billion into domestic data center projects over the next four years," notes TechCrunch. OpenAI also recently signed a cloud deal with Google. "The deal ... underscores the fact that the two are willing to overlook heavy competition between them to meet the massive computing demands," wrote analyst in Reuter's report.

The US Is Now the Largest Investor In Commercial Spyware

An anonymous reader quotes a report from Wired: The United States has emerged as the largest investor in commercial spyware -- a global industry that has enabled the covert surveillance of journalists, human rights defenders, politicians, diplomats, and others, posing grave threats to human rights and national security. In 2024, 20 new US-based spyware investors were identified, bringing the total number of American backers of this technology to 31. This growth has largely outpaced other major investing countries such as Israel, Italy, and the United Kingdom, according to a new report published today by the Atlantic Council. The study surveyed 561 entities across 46 countries between 1992 and 2024, identifying 34 new investors. This brings the total to 128, up from 94 in the dataset published last year. The number of identified investors in the EU Single Market, plus Switzerland, stands at 31, with Italy -- a key spyware hub -- accounting for the largest share at 12. Investors based in Israel number 26. US-based investors include major hedge funds D.E. Shaw & Co. and Millennium Management, prominent trading firm Jane Street, and mainstream financial-services company Ameriprise Financial -- all of which, according to the Atlantic Council, have channeled funds to Israeli lawful-interception software provider Cognyte, a company allegedly linked to human rights abuses in Azerbaijan and Indonesia, among others. [...] Apart from focusing on investment, the Atlantic Council notes that the global spyware market is "growing and evolving," with its dataset expanded to include four new vendors, seven new resellers or brokers, 10 new suppliers, and 55 new individuals linked to the industry. Newly identified vendors include Israel's Bindecy and Italy's SIO. [...] The study reveals the addition of three new countries linked to spyware activity -- Japan, Malaysia, and Panama. Japan in particular is a signatory to international efforts to curb spyware abuse, including the Joint Statement on Efforts to Counter the Proliferation and Misuse of Commercial Spyware and the Pall Mall Process Code of Practice for States. The Atlantic Council's Jen Roberts, who also worked on the report, urged expanding Executive Order 14105 to also include spyware. He also emphasized preserving Executive Order 14093, noting that U.S. purchasing power is a key lever in shaping and constraining the global spyware market. "US purchasing power is a significant tool in shaping and constraining the global market for spyware," said Roberts.

Google is updating Gmail with a new Purchases tab that collects all delivery-related emails in one place, along with package-tracking cards at the top of the inbox for shipments arriving that day. Engadget reports: Each card comes with a "See item" or a "Track Package" button that you can click or tap without having to search for the original delivery email. The new delivery tab will start showing up in your personal Gmail accounts starting today. In addition, Google is updating Gmail's Promotions tab, allowing you to sort the emails in it by "most relevant." Gmail will decide which brands and emails are most relevant for you based on what you've interacted with the most in the past. It will also send you "nudges" on upcoming deals and offers that are set to expire soon. You'll see the changes to the Promotions tab in the coming weeks.
