AI Tools Gave False Information About Tsunami Advisories

Slashdot - Sat, 2025-08-02 19:34
After an 8.8 earthquake off the coast of Russia, "weather authorities leapt into action," reports SFGate, by modeling the threat of a tsunami "and releasing warnings and advisories to prepare their communities..." But some residents of Hawaii, Japan and North America's West Coast turned to AI tools for updates that "appear to have badly bungled the critical task at hand." Google's "AI Overview," for example, reportedly gave "inaccurate information about authorities' safety warnings in Hawaii and elsewhere," according to reports on social media. Thankfully, the tsunami danger quickly subsided on Tuesday night and Wednesday morning without major damage. Still, the issues speak to the growing role of AI tools in people's information diets... and to the tools' potentially dangerous fallibility... A critic of Google — who prompted the search tool to show an AI overview by adding "+ai" to their search — called the text that showed up "dangerously wrong." Responding to similar complaints, Grok told one user on X.com "We'll improve accuracy."

Satellites, Drones, and AI: the New 'High-Tech Quest to Fight Wildfires'

Slashdot - Sat, 2025-08-02 18:34
There's now an "influx" of startups fightging wildfires, reports the Washington Post. "More than 100 new wildfire-related technologies have launched in the U.S. and around the world since 2023, according to Lori Moore-Merrell, who served as U.S. fire administrator during the Biden administration... Unmanned lookout poles that use AI to sense smoke have been erected in the West. Swarms of military-grade drones are increasingly used for wildfire detection and management. AI technology also tracks lightning strikes, which can ignite wildfires..." As America contends with what is already a punishing year of wildfires across massive swaths of the country, new, extremely precise satellite images beamed from space from the initiative FireSat. In March, a satellite outfitted with infrared sensors was launched more than 370 miles into space with the sole task of detecting and monitoring fires. With the ability to loop millions of miles around the planet each day, it found active fires and burn scars using bands of infrared light, demonstrating technology that the project's leaders and its early adopters said could be integral to filling technological gaps in the way they fight burns. The satellite initiative was launched by a nonprofit coalition called Earth Fire Alliance (EFA). Its partners include Muon Space, which is developing the satellites; Google, which is using AI to help filter through the images; the Gordon and Betty Moore Foundation; and the Environmental Defense Fund. The goal is to have 50 satellites in orbit by 2030 to capture the entire world. At full capacity, the constellation is aiming to sweep the entire Earth every 20 minutes to detect small fires. By spring or summer of next year, it plans to launch three more satellites into space that will coordinate with agencies in states including California and Colorado to help them detect and fight fire.

New Steam on Linux Market Share Stats 'Likely the Largest Surveyed Figure Ever'

Slashdot - Sat, 2025-08-02 17:34
"The July 2025 results of the Steam Survey were posted a few minutes ago," Phoronix reported last night, "and show a healthy 0.32% increase to put the Linux gaming marketshare at 2.89%." That's a recent high in percentage terms and while Steam saw around 3% in the early days of Steam on Linux a decade ago, in absolute terms this is likely the largest surveyed figure ever for the Linux gaming population. Linux was at 2.89% for July while macOS was at 1.88% and Windows at 95.23%. There does seem to be a jagged line that's trending upward... November: 2.03% December: 2.29% January: 2.06% February: 1.45% March: 2.33% April: 2.27% May: 2.69% June: 2.57% July: 2.89%

Early Universe's 'Little Red Dots' May Be Black Hole Stars

Slashdot - Sat, 2025-08-02 16:34
After it began "peering into the distant universe" in 2022, NASA's James Webb Space Telescope "has discovered a rash of 'little red dots'," reports Science magazine. There's "hundreds of them, shining within the first billion years of the 13.8-billion-year-old universe, so small and red that they defied conventional explanation." "Only in the past few months has a picture begun to emerge. The little red dots, astronomers say, may be an entirely new type of object: a colossal ball of bright, hot gas, larger than the Solar System, powered not by nuclear fusion, but by a black hole..." The objects, which some astronomers are calling "black hole stars," could be a missing link in the evolution of galaxies and help explain the rapid growth of supermassive black holes that lie at their hearts. "The big breakthrough of the past 6 months is actually the realization that we can throw out all these other models we've been playing with before," says astronomer Anna de Graaff of the Max Planck Institute for Astronomy... JWST couldn't resolve the dots into a recognizable shape, which meant they must have been tiny — less than 2% of the diameter of the Milky Way. "It was a mystery ... as to why they were so spatially compact," says Caitlin Casey of the University of Texas at Austin. An impossibly dense packing of stars would be needed to explain their brightness. "I was excited," Casey says... For Mitch Begelman, a theoretical astrophysicist at the University of Colorado Boulder, the observations are a vindication. Earlier this month, he and a colleague posted a preprint on arXiv reviving a scenario for the formation of hypothetical "quasi-stars" that he and others had proposed 20 years ago. The first generation of stars, they calculated, could have grown to colossal size in the early universe, which was made up almost entirely of hydrogen, the raw material of stars. When a giant star ran out of fuel, they said, its core would have collapsed into a black hole, but the outer envelope of hydrogen was so dense it survived the blast, enclosing the newborn black hole. As the black hole chewed at its shroud of gas, the entire system glowed as a quasi-star larger than the Solar System. "That's what the quasi-star envelope is doing, it's force-feeding the black hole by pushing matter into it," Begelman says. Given how common little red dots appear to be in the early universe, theorists are beginning to wonder whether this giant-ball-of-gas phase is an essential part of black hole growth and the evolution of galaxies. "We're probably looking at kind of a new phase of black hole growth that we didn't know about before," de Graaff says. "If the red dots do turn out to be black hole stars, it will be precisely the sort of breakthrough expected from JWST — and the kind of discovery astronomers live for."

Facing US Chip Restrictions, China Pitches Global Cooperation on AI

Slashdot - Sat, 2025-08-02 15:34
In Shanghai at the World Artificial Intelligence Conference (which ran until Tuesday), the Chinese government "announced an international organization for AI regulation and a 13-point action plan aimed at fostering global cooperation to ensure the technology's beneficial and responsible development," reports the Washington Post. The theme of the conference was "Global Solidarity in the AI Era," the article notes, and "the expo is one part of Beijing's bid to establish itself as a responsible AI leader for the international community." CNN points out that China's announcement comes "just days after the United States unveiled its own plan to promote U.S. dominance." Chinese Premier Li Qiang unveiled China's vision for future AI oversight at the World AI Conference, an annual gathering in Shanghai of tech titans from more than 40 countries... While Li did not directly refer to the U.S. in his speech, he alluded to the ongoing trade tensions between the two superpowers, which include American restrictions on advanced semiconductor exports — a component vital for powering and training AI, which is currently causing a shortage in China. "Key resources and capabilities are concentrated in a few countries and a few enterprises," said Li in his speech on Saturday. "If we engage in technological monopoly, controls and restrictions, AI will become an exclusive game for a small number of countries and enterprises...." Secretary-General of the Association of Southeast Asian Nations, Dr. Kao Kim Hourn, also called for "robust governance" of artificial intelligence to mitigate potential threats, including misinformation, deepfakes, and cybersecurity threats... Former Google CEO Eric Schmidt reiterated the call for international collaboration, explicitly calling on the U.S. and China to work together... "We have a vested interest to keep the world stable, keep the world not at war, to keep things peaceful, to make sure we have human control of these tools." China's plan "called for establishing an international open-source community," reports the Wall Street Journal, "through which AI models can be freely deployed and improved by users." Industry participants said that plan "showed China's ambition to set global standards for AI and could undermine the U.S., whose leading models aren't open-source... While the world's best large language model is still American, the best model that everyone can use free is now Chinese." "The U.S. should commit to ensuring that powerful models remain openly available," argues an opinion piece in The Hill by Stability AI's former head of public policy. Ubiquity is a matter of national security: retreating behind paywalls will leave a vacuum filled by strategic adversaries. Washington should treat open technology not as a vector for Chinese Communist Party propaganda but as a vessel to transmit U.S. influence abroad, molding the global ecosystem around U.S. industry. If DeepSeek is China's open-source "Sputnik moment," we need a legislative environment that supports — not criminalizes — an American open-source Moon landing.

For Sale: a 1990 Airstream Trailer/NASA Command Vehicle for Space Shuttle Landings

Slashdot - Sat, 2025-08-02 14:34
The vehicle "once led the Space Shuttle down the runway at Edwards Air Force Base," The Drive reported in 2022, noting it was won in an auction for $21,061 (beating 18 other bidders). "I just figured the NASA brand combined with Airsteam hip seemed like a can't lose combination," the buyer says now, in a listing for the vehicle on the on the automotive sales site Hemmings.com asking $199,000.. They're touting it as a priceless marketing/publicity prop — "a once in a lifetime opportunity" to own what was once an "onsite command center complete with communications and atmospheric monitoring... Imagine pulling into Burning Man driving this..." The seller points out it's the only custom-built "Airstream" trailer ever sold by NASA. (The others were crushed, except for one donated to the Kennedy museum.) But for this one "Apparently there was some miscommunication when the vehicle was decommissioned. It should have been offered to museums but the sales team did not know what it was.") "Has only 8240 miles on it as driven from Ohio to California then around the Edwards base." The seller apparently first tried listing it on eBay in May for $50,000. ("Reserve not met," says that listing page now. "Very well maintained, minor dings on exterior...")
