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 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."

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.
