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

Fri, 09/12/2025 - 20:10
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

Fri, 09/12/2025 - 19:30
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

Fri, 09/12/2025 - 18:50
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

Fri, 09/12/2025 - 18:10
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

Fri, 09/12/2025 - 17:30
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

Fri, 09/12/2025 - 16:50
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."

California Bill Lets Renters Escape Exclusive Deals Between ISPs and Landlords

Fri, 09/12/2025 - 16:10
California's legislature this week approved a bill to let renters opt out of bulk-billing arrangements that force them to pay for Internet service from a specific provider. ArsTechnica: The bill says that by January 1, a landlord must "allow the tenant to opt out of paying for any subscription from a third-party Internet service provider, such as through a bulk-billing arrangement, to provide service for wired Internet, cellular, or satellite service that is offered in connection with the tenancy." If a landlord fails to do so, the tenant "may deduct the cost of the subscription to the third-party Internet service provider from the rent," and the landlord would be prohibited from retaliating. The bill passed the state Senate in a 30-7 vote on Wednesday but needs Gov. Gavin Newsom's signature to become law. It was approved by the state Assembly in a 75-0 vote in April. Assemblymember Rhodesia Ransom, a Democratic lawmaker who authored the bill, told Ars today that lobby groups for Internet providers and real estate companies have been "working really hard" to defeat it. But she expects Newsom will approve. "I strongly believe that the governor is going to look at what this bill provides as far as protections for tenants and sign it into law," Ransom said in a phone interview.

EU Countries Delay Deal on New Climate Goal, Diplomats Say

Fri, 09/12/2025 - 15:30
An anonymous reader shares a report: European Union countries have shelved plans to approve a new climate change target next week, after pushback from governments including France and Germany over plans to quickly land a deal, three EU diplomats told Reuters on Friday. Countries are discussing a legally-binding target to cut net EU greenhouse gas emissions by 90% by 2040, from 1990 levels - with a share of this covered by buying foreign carbon credits. The European Commission has said this would offer investors certainty and keep Europe on track for net zero emissions by 2050. Climate change has made Europe the world's fastest-warming continent, unleashing deadly heatwaves and record-breaking wildfires. But EU governments are divided over how ambitious to be in tackling global warming, as governments also try to increase defence spending and support struggling industries.

Colleges Are About to See a Big Decline in Applicants

Fri, 09/12/2025 - 14:54
US colleges face a prolonged enrollment decline beginning this fall as high school graduating classes shrink for the first time since the Great Recession. The incoming freshman class marks the start of a 13% drop in high school graduates through 2041, falling from 3.9 million to 3.4 million students. The decline stems from reduced birth rates during the 2008 financial crisis and subsequent years. Regional four-year institutions in the Northeast and Midwest states face potential applicant pool contractions of 15% or more. Small liberal arts colleges, comprising 40% of the higher education market, are particularly vulnerable. 40% of private colleges posted financial losses in 2023. Top-ranked schools in the US News top 50 are expected to experience minimal impact due to sustained national demand for limited seats.

Coffee Prices Post Largest Annual Jump Since 1997

Fri, 09/12/2025 - 14:10
US retail coffee prices surged 21% year-over-year in August, the largest annual increase since October 1997, according to Thursday's Consumer Price Index. The monthly 4% jump marks the steepest rise in 14 years. Trump administration tariffs on major coffee exporters -- 50% on Brazil, 20% on Vietnam, and 10% on Colombia -- are driving costs higher as 99% of US coffee consumption relies on imports. J.M. Smucker plans its third price increase this winter for Folgers and Cafe Bustelo brands after raising prices in May and August. New Orleans chain French Truck Coffee has implemented a 4% tariff surcharge. Starbucks expects peak cost impacts in 2026 due to its advance purchasing practices. KPMG chief economist Diane Swonk predicts prices will exceed historical records as Brazilian tariff effects reach retail shelves.

Microsoft is Making 'Significant Investments' in Training Its Own AI Models

Fri, 09/12/2025 - 12:13
A anonymous reader shares a report: Microsoft AI launched its first in-house models last month, adding to the already complicated relationship with its OpenAI partner. Now, Microsoft AI chief Mustafa Suleyman says the company is making "significant investments" in the compute capacity required to Microsoft's own future frontier models. "We should have the capacity to build world class frontier models in house of all sizes, but we should be very pragmatic and use other models where we need to," said Suleyman during Microsoft's employee-only town hall on Thursday. "We're also going to be making significant investments in our own cluster, so today MAI-1-preview was only trained on 15,000 H100s, a tiny cluster in the grand scheme of things." Suleyman hinted that Microsoft has ambitions to train models that are comparable to Meta, Google, and xAI's efforts on clusters that are "six to ten times larger in size" than what Microsoft used for its MAI-1-preview. "Much more to do, but it's good to take the first steps," said Suleyman.

AI-generated Medical Data Can Sidestep Usual Ethics Review, Universities Say

Fri, 09/12/2025 - 11:02
An anonymous reader shares a report: Medical researchers at some institutions in Canada, the United States and Italy are using data created by artificial intelligence (AI) from real patient information in their experiments without the need for permission from their institutional ethics boards, Nature has learnt. To generate what is called 'synthetic data', researchers train generative AI models using real human medical information, then ask the models to create data sets with statistical properties that represent, but do not include, human data. Typically, when research involves human data, an ethics board must review how studies affect participants' rights, safety, dignity and well-being. However, institutions including the IRCCS Humanitas Research Hospital in Milan, Italy, the Children's Hospital of Eastern Ontario (CHEO) in Ottawa and the Ottawa Hospital, both in Canada, and Washington University School of Medicine (WashU Medicine) in St. Louis, Missouri, have waived these requirements for research involving synthetic data. The reasons the institutions use to justify this decision differ. However, the potential benefits of using synthetic data include protecting patient privacy, being more easily able to share data between sites and speeding up research, says Khaled El Emam, a medical AI researcher at the CHEO Research Institute and the University of Ottawa.

Google is Shutting Down Tables, Its Airtable Rival

Fri, 09/12/2025 - 10:21
Google Tables, a work-tracking tool and competitor to the popular spreadsheet-database hybrid Airtable, is shutting down. TechCrunch: In an email sent to Tables users this week, Google said the app will not be supported after December 16, 2025, and advised that users export or migrate their data to either Google Sheets or AppSheet instead, depending on their needs. Launched in 2020, Tables focused on making project tracking more efficient with automation. It was one of the many projects to emerge from Google's in-house app incubator, Area 120, which at the time was devoted to cranking out a number of experimental projects. Some of these projects later graduated to become a part of Google's core offerings across Cloud, Search, Shopping, and more. Tables was one of those early successes: Google said in 2021 that the service was moving from a beta test to become an official Google Cloud product. At the time, the company said it saw Tables as a potential solution for a variety of use cases, including project management, IT operations, customer service tracking, CRM, recruiting, product development and more.

Swiss Government Looks To Undercut Privacy Tech, Stoking Fears of Mass Surveillance

Fri, 09/12/2025 - 09:40
The Swiss government could soon require service providers with more than 5,000 users to collect government-issued identification, retain subscriber data for six months and, in many cases, disable encryption. From a report: The proposal, which is not subject to parliamentary approval, has alarmed privacy and digital-freedoms advocates worldwide because of how it will destroy anonymity online, including for people located outside of Switzerland. A large number of virtual private network (VPN) companies and other privacy-preserving firms are headquartered in the country because it has historically had liberal digital privacy laws alongside its famously discreet banking ecosystem. Proton, which offers secure and end-to-end encrypted email along with an ultra-private VPN and cloud storage, announced on July 23 that it is moving most of its physical infrastructure out of Switzerland due to the proposed law. The company is investing more than $117 million in the European Union, the announcement said, and plans to help develop a "sovereign EuroStack for the future of our home continent." Switzerland is not a member of the EU. Proton said the decision was prompted by the Swiss government's attempt to "introduce mass surveillance."

Nepal's Social Media Ban Backfires as Politics Moves To a Chat Room

Fri, 09/12/2025 - 09:01
An anonymous reader shares a report: An attempt to ban social media in Nepal ended this week in violent protest with the prime minister ousted, the Parliament in flames and soldiers on the streets of the capital. Now, the very technology the government tried to outlaw is being harnessed to help select the country's next leader, as more than 100,000 citizens are meeting regularly in a virtual chat room to debate the country's future. More than 30 people were killed in clashes with the police during youth-led protests that convulsed the capital in a paroxysm of outrage over wealth inequality, corruption and plans to ban some social media platforms. After the government's collapse on Tuesday, the military imposed a curfew across the capital, Kathmandu, and restricted large gatherings. With the country in political limbo and no obvious next leader in place, Nepalis have taken to Discord, a platform popularized by video gamers, to enact the digital version of a national convention. "The Parliament of Nepal right now is Discord," said Sid Ghimiri, 23, a content creator from Kathmandu, describing how the site has become the center of the nation's political decision making. The conversation inside the Discord channel, taking place in a combination of voice, video, and text chats, is so consequential that it is being discussed on national television and live streamed on news sites.

Apache Software Foundation Unveils Its Branding Overhaul With New Logo, 'The ASF' Name

Fri, 09/12/2025 - 08:00
The Apache Software Foundation has unveiled a major branding overhaul that retires its three-decade-old feather logo after criticism from Native American activists. In its place is a new oak leaf design to symbolize endurance, resilience, and global reach. Along with the new visual identity, the group will emphasize "The ASF" as its shorthand name while keeping its full legal title intact. Apache.org explained: "The oak is one of the most enduring trees and is found around the world. It grows slowly but steadily, supporting vast ecosystems and lasting for centuries. In the same way, The ASF has served as a stable, resilient steward of open source for more than 25 years and is looking to the long future ahead. Choosing the oak leaf as our new logo represents the enduring power of our ethos: community over code."

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

Fri, 09/12/2025 - 05:00
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

Fri, 09/12/2025 - 02:00
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.
