Sweden could become an important source of rare earth elements needed for magnets and green technologies。 Instead of extracting one target metal, researchers are cataloging everything contained in Swedish mineral deposits。 They will then develop magnets using those naturally available combinations, potentially reducing pollution, waste, and relianc
Newer oral drugs related to semaglutide medications such as Ozempic reduced pleasure-driven eating in mice by quieting a deep brain reward circuit。 The finding could open new avenues for understanding food cravings and potentially treating substance use disorder
A new analysis has precisely dated paintings in France’s Font-de-Gaume cave for the first time。 Scientists discovered charcoal inside black pigments once thought to contain only minerals, allowing them to use radiocarbon dating。 The results show that a bison was painted about 13,000 years ago, while sections of a mask-like figure were added during
MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts。 Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals。 In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view
Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone。 The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space。 Located 48 light-years away, the world may have preserved its atmosphere for billions of years, making it a promising target in the search for potenti
A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust。 Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal。 During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, allowing crews and ground teams to test the complex maneuvers needed for later missions
HN is great for the links people share, but a big part of the value I get comes from reading the discussion around them。 I realized I was always opening the article in one tab and the comments in another, constantly switching back and forth。I figured there was probably a simpler way, so I threw together this userscript to merge the two
In a new disclosure, OpenAI says its agent used exposed logins to gain access to at least four “publicly available services” in its unhinged quest to solve a test
A notorious snake invasion that devastated Guam’s native birds may have succeeded because the reptiles carried hidden genetic advantages。 Using advanced long-read DNA sequencing, researchers uncovered more than 19,000 large genetic differences in brown tree snakes, many concentrated in genes tied to immunity and smell。 This overlooked diversity may
Claude Mythos Preview discovered new attacks in testing against weakened cryptographic algorithms, which protect online financial transactions, private communications and more
“We're in the realm where we might be essentially killing off everything within that first hour or two
CapuchinAI, a portable testing station equipped with a touch screen and facial recognition software, could help scientists study primate intelligence in the wild
How much could a single underscore in a username really matter。 Just ask Brandon Klayme, who served 18 months in prison before realizing how authorities arrested, charged, and convicted the wrong man
The chipmaking giant is in talks with OpenAI to provide a $250 billion financial backstop for the project, which would be among the largest of the A
NASA astronaut Chris Williams and two Roscosmos cosmonauts are back on Earth after spending 241 days aboard the International Space Station。 Their journey covered more than 102 million miles and included 3,856 trips around the planet
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy。 The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass
Dyson’s new stick vacuum can vacuum and mop in a single cordless device—if you’re willing to really splurge
"Preliminary investigation shows that two of Link's three reaction wheels currently are not operable
Investigators in Europe said that the cryptocurrency giant Binance had made it more difficult to track down scammers and solve other crimes
