A new study challenges the Nobel-winning theory that the universe's expansion is accelerating, suggesting instead that it may be slowing down as dark energy weakens -- potentially leading to a future "big crunch" where the cosmos collapses back in on itself. "Our study shows that the universe has already entered a phase of decelerated expansion at the present epoch and that dark energy evolves with time much more rapidly than previously thought," said Prof Young-Wook Lee, of Yonsei University in South Korea, who led the work. "If these results are confirmed, it would mark a major paradigm shift in cosmology since the discovery of dark energy 27 years ago." The Guardian reports: The latest work focuses on the reliability of observations of distant supernovae (exploding stars) that led to the discovery of dark energy, work that was awarded the 2011 Nobel prize in physics. [...] By estimating the ages of 300 host galaxies using a different method, the team concluded that there are simply variations in the properties of stars in the early universe that mean they produce, on average, fainter supernovae. Correcting for this systematic bias still results in an expanding universe, but suggests that the expansion has slowed down and that dark energy is waning, the analysis concluded. If dark energy keeps decreasing to the point where it becomes negative, the universe is theoretically predicted to end in a big crunch. The findings are published in Monthly Notices of the Royal Astronomical Society.

An anonymous reader quotes a report from MIT Technology Review: The US- and UK-based company Quantinuum today unveiled Helios, its third-generation quantum computer, which includes expanded computing power and error correction capability. Like all other existing quantum computers, Helios is not powerful enough to execute the industry's dream money-making algorithms, such as those that would be useful for materials discovery or financial modeling. But Quantinuum's machines, which use individual ions as qubits, could be easier to scale up than quantum computers that use superconducting circuits as qubits, such as Google's and IBM's. "Helios is an important proof point in our road map about how we'll scale to larger physical systems," says Jennifer Strabley, vice president at Quantinuum, which formed in 2021 from the merger of Honeywell Quantum Solutions and Cambridge Quantum. Honeywell remains Quantinuum's majority owner. Located at Quantinuum's facility in Colorado, Helios comprises a myriad of components, including mirrors, lasers, and optical fiber. Its core is a thumbnail-size chip containing the barium ions that serve as the qubits, which perform the actual computing. Helios computes with 98 barium ions at a time; its predecessor, H2, used 56 ytterbium qubits. The barium ions are an upgrade, as they have proven easier to control than ytterbium. These components all sit within a chamber that is cooled to about 15 Kelvin (-432.67 ), on top of an optical table. Users can access the computer by logging in remotely over the cloud. [...] Helios is noteworthy for its qubits' precision, says Rajibul Islam, a physicist at the University of Waterloo in Canada, who is not affiliated with Quantinuum. The computer's qubit error rates are low to begin with, which means it doesn't need to devote as much of its hardware to error correction. Quantinuum had pairs of qubits interact in an operation known as entanglement and found that they behaved as expected 99.921% of the time. "To the best of my knowledge, no other platform is at this level," says Islam. [...] Besides increasing the number of qubits on its chip, another notable achievement for Quantinuum is that it demonstrated error correction "on the fly," says David Hayes, the company's director of computational theory and design, That's a new capability for its machines. Nvidia GPUs were used to identify errors in the qubits in parallel. Hayes thinks that GPUs are more effective for error correction than chips known as FPGAs, also used in the industry. Quantinuum has used its computers to investigate the basic physics of magnetism and superconductivity. Earlier this year, it reported simulating a magnet on H2, Quantinuum's predecessor, with the claim that it "rivals the best classical approaches in expanding our understanding of magnetism." Along with announcing the introduction of Helios, the company has used the machine to simulate the behavior of electrons in a high-temperature superconductor. Quantinuum is expanding its Helios line with a new system in Minnesota. It's also started developing its fourth-generation quantum computer, Sol, set for 2027 with 192 qubits. Then, a fifth-generation system, Apollo, is expected in 2029 with thousands of qubits and full fault tolerance.

A bungled October 18 heist that saw $102 million of crown jewels stolen from the Louvre in broad daylight has exposed years of lax security at the national art museum. From trivial passwords like 'LOUVRE' to decades-old, unsupported systems and easy rooftop access, the job was made surprisingly easy. PC Gamer reports: As Rogue cofounder and former Polygon arch-jester Cass Marshall notes on Bluesky, we owe a lot of videogame designers an apology. We've spent years dunking on the emptyheadedness of game characters leaving their crucial security codes and vault combinations in the open for anyone to read, all while the Louvre has been using the password "Louvre" for its video surveillance servers. That's not an exaggeration. Confidential documents reviewed by Liberation detail a long history of Louvre security vulnerabilities, dating back to a 2014 cybersecurity audit performed by the French Cybersecurity Agency (ANSSI) at the museum's request. ANSSI experts were able to infiltrate the Louvre's security network to manipulate video surveillance and modify badge access. "How did the experts manage to infiltrate the network? Primarily due to the weakness of certain passwords which the French National Cybersecurity Agency (ANSSI) politely describes as 'trivial,'" writes Liberation's Brice Le Borgne via machine translation. "Type 'LOUVRE' to access a server managing the museum's video surveillance, or 'THALES' to access one of the software programs published by... Thales." The museum sought another audit from France's National Institute for Advanced Studies in Security and Justice in 2015. Concluded two years later, the audit's 40 pages of recommendations described "serious shortcomings," "poorly managed" visitor flow, rooftops that are easily accessible during construction work, and outdated and malfunctioning security systems. Later documents indicate that, in 2025, the Louvre was still using security software purchased in 2003 that is no longer supported by its developer, running on hardware using Windows Server 2003.

A new survey of over 300 US and UK gaming executives found that 72% view Steam as a monopoly. "Furthermore, 88% said that at least three-quarters of their revenue came from Steam, while 37% reported that the platform accounted for 90% of their total revenue," adds Techspot. From the report: Atomik Research conducted the recent survey on behalf of Rokky, a company that helps game publishers minimize the impact of grey market key resellers on prices. In addition to opinions on Steam, developers also answered questions about the PC market's biggest challenges. The increasing popularity of free-to-play games such as Fortnite, DOTA 2, Counter-Strike 2, Call of Duty: Warzone, and Roblox topped the list of concerns for 40% of respondents. Approximately a third mentioned market saturation and discoverability, echoing data that suggests there aren't enough players for the thousands of new titles released on Steam each year. A similar portion of survey respondents also expressed concerns regarding subscription services.

An anonymous reader quotes a report from the Associated Press: Google Maps is heading in a new direction with artificial intelligence sitting in the passenger's seat. Fueled by Google's Gemini AI technology, the world's most popular navigation app will become a more conversational companion as part of a redesign announced Wednesday. The hands-free experience is meant to turn Google Maps into something more like an insightful passenger able to direct a driver to a destination while also providing nearby recommendations on places to eat, shop or sightsee, when asked for the advice. "No fumbling required -- now you can just ask," Google promised in a blog post about the app makeover. The AI features are also supposed to enable Google Maps to be more precise by calling out landmarks to denote the place to make a turn instead of relying on distance notifications. AI chatbots, like Gemini and OpenAI's ChatGPT, have sometimes lapsed into periods of making things up -- known as "hallucinations" in tech speak -- but Google is promising that built-in safeguards will prevent Maps from accidentally sending drivers down the wrong road. All the information that Gemini is drawing upon will be culled from the roughly 250 million places stored in Google Maps' database of reviews accumulated during the past 20 years. Google Maps' new AI capabilities will be rolling out to both Apple's iPhone and Android mobile devices.

A new bipartisan bill introduced by Senators Mark Warner and Josh Hawley would require companies and federal agencies to report quarterly on AI-related workforce changes, including layoffs, new hires, and retraining efforts. The data from the AI-Related Job Impacts Clarity Act (PDF) would then be compiled by the Department of Labor into a publicly available report. "This bipartisan legislation will finally give us a clear picture of AI's impact on the workforce," Warner said in a statement. "Armed with this information, we can make sure AI drives opportunity instead of leaving workers behind."

A new Activate Consulting report reveals that 43% of Gen Z now prefer YouTube and TikTok over traditional TV or paid streaming. With global media revenues surging and traditional TV viewership collapsing, the average person now spends over 13 hours a day consuming content across platforms, effectively living a "32-hour day" through multitasking. Variety reports: Per the same survey, the popularity of "microdramas" -- one of the latest trends on those platforms, consisting of 1-2 minute scripted episodes of an ongoing storyline -- has been increasing at a fast rate with 28 million U.S. adults (52% aged 18-34) reportedly watching that new form of content. Additional findings include projections for global internet and media revenue to increase by $388 billion by 2029, while average daily time spent streaming video will climb to 4 hours and 8 minutes as time spent watching traditional TV is set to collapse to just 1 hour and 17 minutes. Activate estimates that, as a result, streaming revenues (from ads and subscriptions) will grow 18-19% annually while traditional TV revenues will fall 4-6% year to year.

An anonymous reader quotes a report from the Guardian: Authorities in Denmark are urgently studying how to close an apparent security loophole in hundreds of Chinese-made electric buses that enables them to be remotely deactivated. The investigation comes after transport authorities in Norway, where the Yutong buses are also in service, found that the Chinese supplier had remote access for software updates and diagnostics to the vehicles' control systems -- which could be exploited to affect buses while in transit. Amid concerns over potential security risks, the Norwegian public transport authority Ruter decided to test two electric buses in an isolated environment. Bernt Reitan Jenssen, Ruter's chief executive, said: "The testing revealed risks that we are now taking measures against. National and local authorities have been informed and must assist with additional measures at a national level." Their investigations found that remote deactivation could be prevented by removing the buses' sim cards, but they decided against this because it would also disconnect the bus from other systems. Ruter said it planned to bring in stricter security requirements for future procurements. Jenssen said it must act before the arrival of the next generation of buses, which could be even "more integrated and harder to secure." Movia, Denmark's largest public transport company, has 469 Chinese electric buses in operation -- 262 of which were manufactured by Yutong. Jeppe Gaard, Movia's chief operating officer, said he was made aware of the loophole last week. "This is not a Chinese bus problem," he said. "It is a problem for all types of vehicles and devices with Chinese electronics built in."

An anonymous reader shares a report: T-Mobile is opening up access to its Starlink-powered emergency texting service. The carrier announced on Wednesday that anyone with a compatible phone -- even AT&T and Verizon customers -- can sign up to text 911 over satellite for free. In July, T-Mobile launched its "T-Satellite" service to customers across the US for $10 per month, allowing both T-Mobile and non-T-Mobile customers to send messages, share their location, and access select apps over satellite. This service also includes texts to 911, but now, that's available for free.

Nothing has announced that it will allow users to delete Facebook, Instagram and other Meta services from its mid-range and entry-level phones after users objected to the company's decision to pre-install these apps. The update will arrive by the end of November for devices running the Android 16-based OS 4.0 on the Phone (3a) series. Nothing said it will continue to pre-install partner apps on non-flagship devices in most regions. Devices in the United Kingdom, European Union and Japan will also come with TikTok installed by default. The company defended the practice by saying most users rely on these apps and that pre-installing them allows faster cold starts. Carl Pei's company blamed razor-thin margins on mid-range devices for the decision to bundle third-party software. Nothing did not address whether users can uninstall the service that powers newly introduced lock screen advertisements, which the company previously described as disabled by default and standard across the industry.

Solar geoengineering could increase the ferocity of North Atlantic hurricanes, cause the Amazon rainforest to die back and cause drought in parts of Africa if deployed above only some parts of the planet by rogue actors, a report has warned. The Guardian: However, if technology to block the sun was used globally and in a coordinated way for a long period -- decades or even centuries -- there is strong evidence that it would lower the global temperature, the review from the UK's Royal Society concluded. The world is failing to halt the climate crisis and the researchers said that in future, a judgment might need to be made between the risks of geoengineering and the those of continued global heating, which is already costing lives and livelihoods. The logistics of a large-scale geoengineering effort would be daunting, the experts said, but the cost would be small relative to climate action -- billions of dollars a year against trillions. The researchers emphasised that geoengineering only masked the symptoms of the climate crisis, and did not tackle the root cause -- the burning of fossil fuels. Geoengineering could only complement the cutting of emissions, not replace it, they said. If geoengineering was halted abruptly but emissions had not been reduced, there would be a termination shock of rapidly rising temperatures -- 1-2C within a couple of decades -- that would have severe effects on people and ecosystems unable to rapidly adapt.

Financial Times: Deutsche Bank is exploring ways to hedge its exposure to data centres after extending billions of dollars in debt to the sector to keep up with demand for artificial intelligence and cloud computing. Executives inside the bank have discussed ways to manage its exposure to the booming industry as so-called hyperscalers pour hundreds of billions of dollars into building infrastructure for their AI needs that is increasingly funded by debt. The German lender is looking at options including shorting a basket of AI-related stocks that would help mitigate downside risk by betting against companies in the sector. It is also considering buying default protection on some of the debt using derivatives through a transaction known as synthetic risk transfer (SRT). Deutsche's investment banking business has "bet big" on data centre financing, according to one senior executive. However, the scale of expenditure on AI infrastructure has prompted concerns that a bubble is forming with some likening the enthusiasm to that which preceded the dotcom crash. Sceptics have pointed out that billions of dollars have been deployed in an untested industry with assets that quickly depreciate in value due to the rapid change in technology.

The Chinese government has issued guidance requiring new data centre projects that have received any state funds to only use domestically-made AI chips, Reuters reported Wednesday, citing sources familiar with the matter. From the report: In recent weeks, Chinese regulatory authorities have ordered such data centres that are less than 30% complete to remove all installed foreign chips, or cancel plans to purchase them, while projects in a more advanced stage will be decided on a case-by-case basis, the sources said. The move could represent one of China's most aggressive steps yet to eliminate foreign technology from its critical infrastructure amid a pause in trade hostilities between Washington and Beijing, and achieve its quest for AI chip self-sufficiency. China's access to advanced AI chips, including those made by Nvidia, has been a key point of friction with the U.S., as the two wrestle for dominance in high-end computing power and AI. U.S. President Donald Trump said in an interview aired on Sunday following talks with Chinese President Xi Jinping last week that Washington will "let them deal with Nvidia but not in terms of the most advanced" chips.

Epic Games and Google have agreed to settle their long-running antitrust lawsuit. The settlement converts Judge James Donato's United States-only injunction into a global agreement extending through June 2032. Google will reduce its standard app store fees to either 20% or 9% depending on the transaction type. The company will also create a program in the next major Android release allowing alternative app stores to register and become what Google calls first-class citizens. Users will be able to install these registered app stores from a website with a single click using neutral language. The settlement addresses Epic's concerns about friction and scare screens that discouraged sideloading. Google will charge a 5% fee for transactions using Google Play Billing, separate from its service fee. Alternative payment options must be shown alongside Google Play Billing.

An anonymous reader quotes a report from CNN: An Antarctic glacier shrunk by nearly 50% in just two months, the fastest retreat recorded in modern history, according to a new study -- and the way it retreated could have big implications for global sea level rise. The Hektoria Glacier, roughly the size of Philadelphia, is on the Antarctic Peninsula, a spindly chain of mountains sticking off the continent like a thumb pointing toward South America. It is one of the fastest warming regions on Earth. Grounded glaciers like Hektoria, which rest on the seabed and don't float, generally retreat no more than a few hundred meters a year. But between November and December 2022, Hektoria retreated by 5 miles, according to the study published Monday in the journal Nature Geoscience. [...] Understanding more about why this happened is vital; if larger glaciers retreat at similar rates, it could have "catastrophic implications for sea level rise," the authors wrote in a statement accompanying the report. Antarctica holds enough ice to raise global sea level by around 190 feet. Models show that the latest time this kind of ice plain melting occurred was between about 15,000 and 19,000 years ago, "during a period of warming that ended the last Ice Age," notes the report. "[W]e hadn't seen it play out live before, certainly not at this rate," said Naomi Ochwat, a study co-author and postdoctoral associate at the University of Colorado Boulder.

Bruce66423 shares a report from the Los Angeles Times: The board of the Los Angeles Department of Water and Power on Tuesday approved a controversial plan to convert part of the city's largest natural gas-fired power plant into one that also can burn hydrogen. In a 3-0 vote, the DWP board signed off on the final environmental impact report for an $800-million modernization of Units 1 and 2 of the Scattergood Generating Station in Playa del Rey. The power plant dates to the late 1950s and both units are legally required to be shut down by the end of 2029. In their place, the DWP will install new combined-cycle turbines that are expected to operate on a mixture of natural gas and at least 30% hydrogen with the ultimate goal of running entirely on hydrogen as more supply becomes available. The hydrogen burned at Scattergood is supposed to be green, meaning it is produced by splitting water molecules through a process called electrolysis. Hydrogen does not emit planet-warming carbon dioxide when it is burned, unlike natural gas. [...] Although burning hydrogen does not produce CO2, the high-temperature combustion process can emit nitrogen oxides, or NOx, a key component of smog. [...] [T]he approved plan contains no specifics about where the hydrogen will come from or how it will get to the site. "The green hydrogen that would supply the proposed project has not yet been identified," the environmental report says. Industry experts and officials said the project will help drive the necessary hydrogen production. "Burning hydrogen produced by 'excess' solar or wind power is a means of energy storage," adds Slashdot reader Bruce66423. "The hard question is whether it's the best solution to the storage problem given that other solutions appear to be emerging that would require less infrastructure investment (think pipes to move the hydrogen to the plant and tanks to store it for later use)."

A new class-action lawsuit accuses Spotify of allowing billions of fraudulent Drake streams generated by bots between 2022 and 2025, allegedly inflating his royalties at the expense of other artists. "Spotify pays streaming royalties using a 'pro-rata' model based on an artist's market share," notes Consequence. "Each month, revenue from subscriptions and ads is collected into a single, fixed 'pot' of money, which is then distributed to rights holders based on their percentage of the platform's total streams. Because this pot is fixed, an artist who artificially inflates their numbers through bots would dilute the value of every legitimate stream. This allows them to take a larger share of the pot than they earned, effectively siphoning royalties that should have gone to other artists." From the report: According to Rolling Stone, the lawsuit alleges bot use is a widespread problem on Spotify. However, Drake is the only example named, based on "voluminous information" which the company "knows or should know" that proves a "substantial, non-trivial percentage" of his approximately 37 billion streams were "inauthentic and appeared to be the work of a sprawling network of Bot Accounts." The complaint claims this alleged fraudulent activity took place between "January 2022 and September 2025," with an examination of "abnormal VPN usage" revealing at least 250,000 streams of Drake's song "No Face" during a four-day period in 2024 were actually from Turkey "but were falsely geomapped through the coordinated use of VPNs to the United Kingdom in [an] attempt to obscure their origins." Other notable allegations in the lawsuit are that "a large percentage" of accounts were concentrated in areas where the population could not support such a high volume of streams, including those with "zero residential addresses." The suit also points to "significant and irregular uptick months" for Drake's songs long after their release, as well as a "slower and less dramatic" downtick in streams compared to other artists. Noting a "staggering and irregular" streaming of Drake's music by individuals, the suit also claims there are a "massive amount of accounts" listening to his songs "23 hours a day." Less than 2% of those users account for "roughly 15 percent" of his streams. "Drake's music accumulated far higher total streams compared to other highly streamed artists, even though those artists had far more 'users' than Drake," the lawsuit concludes.

concertina226 shares a report from The Register: [A massive power outage in April left tens of millions across Spain, Portugal, and parts of France without electricity for hours due to cascading grid failures, exposing how fragile and interconnected Europe's energy infrastructure is. The incident, though not a cyberattack, reignited concerns about the vulnerability of aging, fragmented, and insecure operational technology systems that could be easily exploited in future cyber or ransomware attacks.] This headache is one the European Commission is focused on. It is funding several projects looking at making electric grids more resilient, such as the eFort framework being developed by cybersecurity researchers at the independent non-profit Netherlands Organisation for Applied Scientific Research (TNO) and the Delft University of Technology (TU Delft). TNO's SOARCA tool is the first ever open source security orchestration, automation and response (SOAR) platform designed to protect power plants by automating the orchestration of the response to physical attacks, as well as cyberattacks, on substations and the network, and the first country to demo it will be the Ukraine this year. At the moment, SOAR systems only exist for dedicated IT environments. The researchers' design includes a SOAR system in each layer of the power station: the substation, the control room, the enterprise layer, the cloud, or the security operations centre (SOC), so that the SOC and the control room work together to detect anomalies in the network, whether it's an attacker exploiting a vulnerability, a malicious device being plugged into a substation, or a physical attack like a missile hitting a substation. The idea is to be able to isolate potential problems and prevent lateral movement from one device to another or privilege escalation, so an attacker cannot go through the network to the central IT management system of the electricity grid. [...] The SOARCA tool is underpinned by CACAO Playbooks, an open source specification developed by the OASIS Open standards body and its members (which include lots of tech giants and US government agencies) to create standardized predefined, automated workflows that can detect intrusions and changes made by malicious actors, and then carry out a series of steps to protect the network and mitigate the attack. Experts largely agree the problem facing critical infrastructure is only worsening as years pass, and the more random Windows implementations that are added into the network, the wider the attack surface is. [...] TNO's Wolthuis said the energy industry is likely to be pushed soon to take action by regulators, particularly once the Network Code on Cybersecurity (NCCS), which lays out rules requiring cybersecurity risk assessments in the electricity sector, is formalized.

An anonymous reader quotes a report from Tom's Hardware: After a turbulent weekend of updates and clarifications, AMD has published an entire web page to assuage user backlash and reaffirm its commitment to continued support for its RDNA 1 and RDNA 2-based drives, following a spate of confusion surrounding its recent decision to put Radeon RX 5000 and 6000 series cards in "maintenance mode." This comes after AMD had to deny that the RX 7900 cards were losing USB-C power supply moving forward, even though the drive changelog said something quite different. Just last week, AMD released a new driver update for its graphics cards, and it went anything but smoothly. First, the wrong drivers were uploaded, and even after that was corrected, several glaring errors in the release notes required clarification. AMD was forced to correct claims about its RX 7900 cards, but at the time clarified that, indeed, RX 5000 and 6000 graphics cards were entering "Maintenance Mode," despite some RX 6000 cards being only around four years old. Now, though, AMD has either rolled back that decision or someone higher up the food chain has made a new call, as game optimizations are back on the menu for RDNA 1 and RDNA 2 GPUs. "We've heard your feedback and want to clear up the confusion around the AMD Software: Adrenalin Edition 25.10.2 driver release," AMD said in a statement. "Your Radeon RX 5000 and RX 6000 series GPUs will continue to receive: Game support for new releases, Stability and game optimizations, and Security and bug fixes," AMD said.
