Are Astronomers Wrong About Dark Energy?

22 novembre 2025 à 20:36
An anonymous reader shared this report from CNN: The universe's expansion might not be accelerating but slowing down, a new study suggests. If confirmed, the finding would upend decades of established astronomical assumptions and rewrite our understanding of dark energy, the elusive force that counters the inward pull of gravity in our universe... Last year, a consortium of hundreds of researchers using data from the Dark Energy Spectroscopic Instrument (DESI) in Arizona, developed the largest ever 3D map of the universe. The observations hinted at the fact that dark energy may be weakening over time, indicating that the universe's rate of expansion could eventually slow. Now, a study published November 6 in the journal Monthly Notices of the Royal Astronomical Society provides further evidence that dark energy might not be pushing on the universe with the same strength it used to. The DESI project's findings last year represented "a major, major paradigm change ... and our result, in some sense, agrees well with that," said Young-Wook Lee, a professor of astrophysics at Yonsei University in South Korea and lead researcher for the new study.... To reach their conclusions, the researchers analyzed a sample of 300 galaxies containing Type 1a supernovas and posited that the dimming of distant exploding stars was not only due to their moving farther away from Earth, but also due to the progenitor star's age... [Study coauthor Junhyuk Son, a doctoral candidate of astronomy at Yonsei University, said] "we found that their luminosity actually depends on the age of the stars that produce them — younger progenitors yield slightly dimmer supernovae, while older ones are brighter." Son said the team has a high statistical confidence — 99.99% — about this age-brightness relation, allowing them to use Type 1a supernovas more accurately than before to assess the universe's expansion... Eventually, if the expansion continues to slow down, the universe could begin to contract, ending in what astronomers imagine may be the opposite of the big bang — the big crunch. "That is certainly a possibility," Lee said. "Even two years ago, the Big Crunch was out of the question. But we need more work to see whether it could actually happen." The new research proposes a radical revision of accepted knowledge, so, understandably, it is being met with skepticism. "This study rests on a flawed premise," Adam Riess, a professor of physics and astronomy at the Johns Hopkins University and one of the recipients of the 2011 Nobel Prize in physics, said in an email. "It suggests supernovae have aged with the Universe, yet observations show the opposite — today's supernovae occur where young stars form. The same idea was proposed years ago and refuted then, and there appears to be nothing new in this version." Lee, however, said Riess' claim is incorrect. "Even in the present-day Universe, Type Ia supernovae are found just as frequently in old, quiescent elliptical galaxies as in young, star-forming ones — which clearly shows that this comment is mistaken. The so-called paper that 'refuted' our earlier result relied on deeply flawed data with enormous uncertainties," he said, adding that the age-brightness correlation has been independently confirmed by two separate teams in the United States and China... "Extraordinary claims require extraordinary evidence," Dragan Huterer, a professor of physics at the University of Michigan in Ann Arbor, said in an email, noting that he does not feel the new research "rises to the threshold to overturn the currently favored model...." The new Vera C. Rubin Observatory, which started operating this year, is set to help settle the debate with the early 2026 launch of the Legacy Survey of Space and Time, an ultrawide and ultra-high-definition time-lapse record of the universe made by scanning the entire sky every few nights over 10 years to capture a compilation of asteroids and comets, exploding stars, and distant galaxies as they change.

Britain Sets New Record, Generating Enough Wind Power for 22 Million Homes

22 novembre 2025 à 19:34
An anonymous reader shared this report from Sky News: A new wind record has been set for Britain, with enough electricity generated from turbines to power 22 million homes, the system operator has said. The mark of 22,711 megawatts (MW) was set at 7.30pm on 11 November... enough to keep around three-quarters of British homes powered, the National Energy System Operator (Neso) said. The country had experienced windy conditions, particularly in the north of England and Scotland... Neso has predicted that Britain could hit another milestone in the months ahead by running the electricity grid for a period entirely with zero carbon power, renewables and nuclear... Neso said wind power is now the largest source of electricity generation for the UK, and the government wants to generate almost all of the UK's electricity from low-carbon sources by 2030. "Wind accounted for 55.7 per cent of Britain's electricity mix at the time..." reports The Times: Gas provided only 12.5 per cent of the mix, with 11.3 per cent coming from imports over subsea power cables, 8 per cent from nuclear reactors, 8 per cent from biomass plants, 1.4 per cent from hydroelectric plants and 1.1 per cent from storage. Britain has about 32 gigawatts of wind farms installed, approximately half of that onshore and half offshore, according to the Wind Energy Database from the wind industry body Renewable UK. That includes five of the world's biggest offshore wind farms. The government is seeking to double onshore wind and quadruple offshore wind power by 2030 as part of its plan for clean energy.... Jane Cooper, deputy chief executive of Renewable UK, said: "On a cold, dark November evening, wind was generating enough electricity to power 80 per cent of British homes when we needed it most.

Analyzing 47,000 ChatGPT Conversations Shows Echo Chambers, Sensitive Data - and Unpredictable Medical Advice

22 novembre 2025 à 18:34
For nearly three years OpenAI has touted ChatGPT as a "revolutionary" (and work-transforming) productivity tool, reports the Washington Post. But after analyzing 47,000 ChatGPT conversations, the Post found that users "are overwhelmingly turning to the chatbot for advice and companionship, not productivity tasks." The Post analyzed a collection of thousands of publicly shared ChatGPT conversations from June 2024 to August 2025. While ChatGPT conversations are private by default, the conversations analyzed were made public by users who created shareable links to their chats that were later preserved in the Internet Archive and downloaded by The Post. It is possible that some people didn't know their conversations would become publicly preserved online. This unique data gives us a glimpse into an otherwise black box... Overall, about 10 percent of the chats appeared to show people talking about their emotions, role-playing, or seeking social interactions with the chatbot. Some users shared highly private and sensitive information with the chatbot, such as information about their family in the course of seeking legal advice. People also sent ChatGPT hundreds of unique email addresses and dozens of phone numbers in the conversations... Lee Rainie, director of the Imagining the Digital Future Center at Elon University, said that it appears ChatGPT "is trained to further or deepen the relationship." In some of the conversations analyzed, the chatbot matched users' viewpoints and created a personalized echo chamber, sometimes endorsing falsehoods and conspiracy theories. Four of ChatGPT's answers about health problems got a failing score from a chair of medicine at the University of California San, Francisco, the Post points out. But four other answers earned a perfect score.

780,000 Windows Users Downloaded Linux Distro Zorin OS in the Last 5 Weeks

22 novembre 2025 à 17:34
In October Zorin OS claimed it had 100,000 downloads in a little over two days in the days following Microsoft's end of support for Windows 10. And one month later, Zorin OS developers now claim that 780,000 people downloaded it from a Windows computer in the space of a month, according to the tech news site XDA Developers. In a post on the Zorin blog, the developers of the operating system Zorin OS 18 announced that they've managed to accrue one million downloads of the operating system in a single month [since its launch on October 14]. While this is plenty impressive by itself, the developers go on to reveal that, out of that million, 78% of the downloads came from a Windows machine. That means that at least 780,000 people on Windows gave Zorin OS 18 a download... [I]t's easy to see why: the developers put a heavy emphasis on making their system the perfect home for ex-Windows users.

Physicists Reveal a New Quantum State Where Electrons Run Wild

22 novembre 2025 à 16:34
ScienceDaily reports: Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre "pinball" state where some electrons stay locked in place while others dart around freely. Their simulations help explain how these phases form and how they might be harnessed for advanced quantum technologies... When electrons settle into these rigid arrangements, the material undergoes a shift in its state of matter and stops conducting electricity. Instead of acting like a metal, it behaves as an insulator. This unusual behavior provides scientists with valuable insight into how electrons interact and has opened the door to advances in quantum computing, high-performance superconductors used in energy and medical imaging, innovative lighting systems, and extremely precise atomic clocks... [Florida State University assistant professor Cyprian Lewandowski said] "Here, it turns out there are other quantum knobs we can play with to manipulate states of matter, which can lead to impressive advances in experimental research."

Tiny 'Micro-Robots' in your Bloodstream Could Deliver Drugs with Greater Precision

22 novembre 2025 à 15:34
The Washington Post reports: Scientists in Switzerland have created a robot the size of a grain of sand that is controlled by magnets and can deliver drugs to a precise location in the human body, a breakthrough aimed at reducing the severe side effects that stop many medicines from advancing in clinical trials... "I think surgeons are going to look at this," [said Bradley J. Nelson, an author of the paper in Science describing the discovery and a professor of robotics and intelligent systems at ETH Zurich]. I'm sure they're going to have a lot of ideas on how to use" the microrobot. The capsule, which is steered by magnets, might also be useful in treating aneurysms, very aggressive brain cancers, and abnormal connections between arteries and veins known as arteriovenous malformations, Nelson said. The capsules have been tested successfully in pigs, which have similar vasculature to humans, and in silicone models of the blood vessels in humans and animals... Nelson said drug-ferrying microrobots of this kind may be three to five years from being tested in clinical trials. The problem faced by many drugs under development is that they spread throughout the body instead of going only to the area in need... A major cause of side effects in patients is medications traveling to parts of the body that don't need them. The capsules developed in Switzerland, however, can be maneuvered into precise locations by a surgeon using a tool not that different from a PlayStation controller. The navigation system involves six electromagnetic coils positioned around the patient, each about 8 to 10 inches in diameter... The capsules are made of materials that have been found safe for people in other medical tools... When the capsule reaches its destination in the body, "we can trigger the capsule to dissolve," Nelson said.

Court Ends Dragnet Electricity Surveillance Program in Sacramento

Par :BeauHD
22 novembre 2025 à 13:00
A California judge has shut down a decade-long surveillance program in which Sacramento's utility provider shared granular smart-meter data on 650,000 residents with police to hunt for cannabis grows. The EFF reports: The Sacramento County Superior Court ruled that the surveillance program run by the Sacramento Municipal Utility District (SMUD) and police violated a state privacy statute, which bars the disclosure of residents' electrical usage data with narrow exceptions. For more than a decade, SMUD coordinated with the Sacramento Police Department and other law enforcement agencies to sift through the granular smart meter data of residents without suspicion to find evidence of cannabis growing. EFF and its co-counsel represent three petitioners in the case: the Asian American Liberation Network, Khurshid Khoja, and Alfonso Nguyen. They argued that the program created a host of privacy harms -- including criminalizing innocent people, creating menacing encounters with law enforcement, and disproportionately harming the Asian community. The court ruled that the challenged surveillance program was not part of any traditional law enforcement investigation. Investigations happen when police try to solve particular crimes and identify particular suspects. The dragnet that turned all 650,000 SMUD customers into suspects was not an investigation. "[T]he process of making regular requests for all customer information in numerous city zip codes, in the hopes of identifying evidence that could possibly be evidence of illegal activity, without any report or other evidence to suggest that such a crime may have occurred, is not an ongoing investigation," the court ruled, finding that SMUD violated its "obligations of confidentiality" under a data privacy statute. [...] In creating and running the dragnet surveillance program, according to the court, SMUD and police "developed a relationship beyond that of utility provider and law enforcement." Multiple times a year, the police asked SMUD to search its entire database of 650,000 customers to identify people who used a large amount of monthly electricity and to analyze granular 1-hour electrical usage data to identify residents with certain electricity "consumption patterns." SMUD passed on more than 33,000 tips about supposedly "high" usage households to police. [...] Going forward, public utilities throughout California should understand that they cannot disclose customers' electricity data to law enforcement without any "evidence to support a suspicion" that a particular crime occurred.

Ukraine Is Jamming Russia's 'Superweapon' With a Song

Par :BeauHD
22 novembre 2025 à 10:00
Longtime Slashdot reader fahrbot-bot shares a report from 404 Media: The Ukrainian Army is knocking a once-hyped Russian superweapon out of the sky by jamming it with a song and tricking it into thinking it's in Lima, Peru. The Kremlin once called its Kh-47M2 Kinzhal ballistic missiles "invincible." Joe Biden said the missile was "almost impossible to stop." Now Ukrainian electronic warfare experts say they can counter the Kinzhal with some music and a re-direction order. [...] Kinzhals and other guided munitions navigate by communicating with Russian satellites that are part of the GLONASS system, a GPS-style navigation network. Night Watch uses a jamming system called Lima EW to generate a disruption field that prevents anything in the area from communicating with a satellite. Many traditional jamming systems work by blasting receivers on munitions and aircraft with radio noise. Lima does that, but also sends along a digital signal and spoofs navigation signals. It "hacks" the receiver it's communicating with to throw it off course. Night Watch shared pictures of the downed Kinzhals with 404 Media that showed a missile with a controlled reception pattern antenna (CRPA), an active antenna that's meant to resist jamming and spoofing. "We discovered that this missile had pretty old type of technology," Night Watch said. "They had the same type of receivers as old Soviet missiles used to have. So there is nothing special, there is nothing new in those types of missiles." Night Watch told 404 Media that it used this Lima to take down 19 Kinzhals in the past two weeks. First, it replaces the missile's satellite navigation signals with the Ukrainian song "Our Father Is Bandera." Any digital noise or random signal would work to jam the navigation system, but Night Watch wanted to use the song because they think it's funny. "We just send a song... we just make it into binary code, you know, like 010101, and just send it to the Russian navigation system," Night Watch said. "It's just kind of a joke. [Bandera] is a Ukrainian nationalist and Russia tries to use this person in their propaganda to say all Ukrainians are Nazis. They always try to scare the Russian people that Ukrainians are, culturally, all the same as Bandera." Once the song hits, Night Watch uses Lima to spoof a navigation signal to the missiles and make them think they're in Lima, Peru. Once the missile's confused about its location, it attempts to change direction. These missiles are fast -- launched from a MiG-31 they can hit speeds of up to Mach 5.7 or more than 4,000 miles per hour -- and an object moving that fast doesn't fare well with sudden changes of direction.

Magician Forgets Password To His Own Hand After RFID Chip Implant

22 novembre 2025 à 07:00
A magician who implanted an RFID chip in his hand lost access to it after forgetting the password, leaving him effectively locked out of the tech embedded in his own body. The Register reports: "It turns out," said [said magician Zi Teng Wang], "that pressing someone else's phone to my hand repeatedly, trying to figure out where their phone's RFID reader is, really doesn't come off super mysterious and magical and amazing." Then there are the people who don't even have their phone's RFID reader enabled. Using his own phone would, in Zi's words, lack a certain "oomph." Oh well, how about making the chip spit out a Bitcoin address? "That literally never came up either." In the end, Zi rewrote the chip to link to a meme, "and if you ever meet me in person you can scan my chip and see the meme." It was all suitably amusing until the Imgur link Zi was using went down. Not everything on the World Wide Web is forever, and there is no guarantee that a given link will work indefinitely. Indeed, access to Imgur from the United Kingdom was abruptly cut off on September 30 in response to the country's age verification rules. Still, the link not working isn't the end of the world. Zi could just reprogram the chip again, right? Wrong. "When I went to rewrite the chip, I was horrified to realize I forgot the password that I had locked it with." The link eventually started working again, but if and when it stops, Zi's party piece will be a little less entertaining. He said: "Techie friends I've consulted with have determined that it's too dumb and simple to hack, the only way to crack it is to strap on an RFID reader for days to weeks, brute forcing every possible combination." Or perhaps some surgery to remove the offending hardware.

Iran's Capital Is Moving. The Reason Is an Ecological Catastrophe

22 novembre 2025 à 03:30
An anonymous reader quotes a report from Scientific American: Amid a deepening ecological crisis and acute water shortage, Tehran can no longer remain the capital of Iran, the country's president has said. The situation in Tehran is the result of "a perfect storm of climate change and corruption," says Michael Rubin, a political analyst at the American Enterprise Institute. "We no longer have a choice," said Iranian president Masoud Pezeshkian during a speech on Thursday. Instead Iranian officials are considering moving the capital to the country's southern coast. But experts say the proposal does not change the reality for the nearly 10 million people who live in Tehran and are now suffering the consequences of a decades-long decline in water supply. Iran's capital has moved many times over the centuries, notes the report. "But this marks the first time the Iranian government has moved the capital because of an ecological catastrophe." Yet, Rubin says, "it would be a mistake to look at this only through the lens of climate change" and not factor in the water, land, and wastewater mismanagement and corruption that have made the crisis worse. Linda Shi, a social scientist and urban planner at Cornell University, says: "Climate change is not the thing that is causing it, but it is a convenient factor to blame in order to avoid taking responsibility" for poor political decisions.

Cryptographers Cancel Election Results After Losing Decryption Key

22 novembre 2025 à 02:02
The International Association of Cryptologic Research (IACR) was forced to cancel its leadership election after a trustee lost their portion of the Helios voting system's decryption key, making it impossible to reveal or verify the final results. Ars Technica reports: The IACR said Friday that the votes were submitted and tallied using Helios, an open source voting system that uses peer-reviewed cryptography to cast and count votes in a verifiable, confidential, and privacy-preserving way. Helios encrypts each vote in a way that assures each ballot is secret. Other cryptography used by Helios allows each voter to confirm their ballot was counted fairly. "Unfortunately, one of the three trustees has irretrievably lost their private key, an honest but unfortunate human mistake, and therefore cannot compute their decryption share," the IACR said. "As a result, Helios is unable to complete the decryption process, and it is technically impossible for us to obtain or verify the final outcome of this election." The IACR will switch to a two-of-three private key system to prevent this sort of thing from happening again. Moti Yung, the trustee responsible for the incident, has resigned and is being replaced by Michael Abdalla.

SEC Dismisses Case Against SolarWinds, Top Security Officer

Malaysia's Palm Oil Estates Are Turning Into Data Centers

Par :BeauHD
22 novembre 2025 à 00:02
An anonymous reader quotes a report from Bloomberg: Malaysia's palm oil giants, long-blamed for razing rainforests, fueling toxic haze and driving orangutans to the brink of extinction, are recasting themselves as unlikely champions in a different, potentially greener race: the quest to lure the world's AI data centers to the Southeast Asian country (source paywalled; alternative source). Palm oil companies are earmarking some of the vast tracts of land they own for industrial parks studded with data centers and solar panels, the latter meant to feed the insatiable energy appetites of the former. The logic is simple: data centers are power and land hogs. By 2035, they could demand at least five gigawatts of electricity in Malaysia -- almost 20% of the country's current generation capacity and roughly enough to power a major city like Miami. Malaysia also needs space to house server farms, and palm oil giants control more land than any other private entity in the country. The country has been at the heart of a regional data center boom. Last year, it was the fastest-growing data center market in the Asia-Pacific region and roughly 40% of all planned capacity in Southeast Asia is now slated for Malaysia, according to industry consultant DC Byte. Over the past four years, $34 billion in data center investments has poured into the country -- Alphabet's Google committed $2 billion, Microsoft announced a $2.2 billion investment and Amazon is spending $6.2 billion, to name a few. The government aims for 81 data centers by 2035. The rush is partly a spillover from Singapore, where a years-long moratorium on new centers forced operators to look north. Johor, just across the causeway, is now a hive of construction cranes and server farms -- including for firms such as Singapore Telecommunications, Nvidia and ByteDance. But delivering on government promises of renewable power is proving harder. The strains are already being felt in Malaysia's data center capital. Sedenak Tech Park, one of Johor's flagship sites, is telling potential tenants they'll need to wait until the fourth quarter of 2026 for promised water and power hookups under its second-phase expansion, according to DC Byte. The vacancy rate in Johor's live facilities is just 1.1%, according to real estate consultant Knight Frank. Despite its rapid growth, the market is nowhere near saturation, with six gigawatts of capacity expected to be built out over time, said Knight Frank's head of data centers for Asia Pacific, Fred Fitzalan Howard. That potential bottleneck has incentivized palm oil majors such as SD Guthrie Bhd. to pitch themselves as both landowners and green-power suppliers. The $8.9 billion palm oil producer, SD Guthrie, is the world's largest palm oil planter by acreage, with more than 340,000 hectares in Malaysia. "SD Guthrie is pivoting to solar farms and industrial parks, betting that tech giants hungry for server space will prefer sites with ready access to renewable energy," reports Bloomberg. "The company has reserved 10,000 hectares for such projects over the next decade, starting with clearing old rubber estates and low-yielding palm plots in areas near data center and semiconductor investment hubs." "The company's calculation is based on this: one megawatt of solar requires about 1.5 hectares. Helmy said SD Guthrie wants one gigawatt in operation within three years, enough to power up to 10 hyperscale data centers used for AI computing. The new business is expected to make up about a third of its profits by the end of the decade."

Google Must Double AI Serving Capacity Every 6 Months To Meet Demand

Par :BeauHD
21 novembre 2025 à 22:40
Google's AI infrastructure chief told employees the company must double its AI serving capacity every six months in order to meet demand. In a presentation earlier this month, Amin Vahdat, a vice president at Google Cloud, gave a presentation titled "AI Infrastructure." It included a slide on "AI compute demand" that said: "Now we must double every 6 months.... the next 1000x in 4-5 years." CNBC reports: The presentation was delivered a week after Alphabet reported better-than-expected third-quarter results and raised its capital expenditures forecast for the second time this year, to a range of $91 billion to $93 billion, followed by a "significant increase" in 2026. Hyperscaler peers Microsoft, Amazon and Meta also boosted their capex guidance, and the four companies now expect to collectively spend more than $380 billion this year. Google's "job is of course to build this infrastructure but it's not to outspend the competition, necessarily," Vahdat said. "We're going to spend a lot," he said, adding that the real goal is to provide infrastructure that is far "more reliable, more performant and more scalable than what's available anywhere else." In addition to infrastructure build-outs, Vahdat said Google bolsters capacity with more efficient models and through its custom silicon. Last week, Google announced the public launch of its seventh generation Tensor Processing Unit called Ironwood, which the company says is nearly 30 times more power efficient than its first Cloud TPU from 2018. Vahdat said the company has a big advantage with DeepMind, which has research on what AI models can look like in future years. Google needs to "be able to deliver 1,000 times more capability, compute, storage networking for essentially the same cost and increasingly, the same power, the same energy level," Vahdat said. "It won't be easy but through collaboration and co-design, we're going to get there."

Tech Company CTO and Others Indicted For Exporting Nvidia Chips To China

21 novembre 2025 à 22:02
An anonymous reader quotes a report from Ars Technica: The US crackdown on chip exports to China has continued with the arrests of four people accused of a conspiracy to illegally export Nvidia chips. Two US citizens and two nationals of the People's Republic of China (PRC), all of whom live in the US, were charged in an indictment (PDF) unsealed on Wednesday in US District Court for the Middle District of Florida. The indictment alleges a scheme to send Nvidia "GPUs to China by falsifying paperwork, creating fake contracts, and misleading US authorities," John Eisenberg, assistant attorney general for the Justice Department's National Security Division, said in a press release yesterday. The four arrestees are Hon Ning Ho (aka Mathew Ho), a US citizen who was born in Hong Kong and lives in Tampa, Florida; Brian Curtis Raymond, a US citizen who lives in Huntsville, Alabama; Cham Li (aka Tony Li), a PRC national who lives in San Leandro, California; and Jing Chen (aka Harry Chen), a PRC national who lives in Tampa on an F-1 non-immigrant student visa. The suspects face a raft of charges for conspiracy to violate the Export Control Reform Act of 2018, smuggling, and money laundering. They could serve many decades in prison if convicted and given the maximum sentences and forfeit their financial gains. The indictment says that Chinese companies paid the conspirators nearly $3.9 million. One of the suspects was briefly the CTO of Corvex, a Virginia-based AI cloud computing company that is planning to go public. Corvex told CNBC yesterday that it "had no part in the activities cited in the Department of Justice's indictment," and that "the person in question is not an employee of Corvex. Previously a consultant to the company, he was transitioning into an employee role but that offer has been rescinded."
