A new 3D printing technique can produce exceptionally hard tungsten carbide cobalt while using less of its expensive raw materials。 By softening rather than fully melting the material, researchers created defect-free samples with industrial-grade hardness and opened the door to more efficient manufacturing
A tiny 518-million-year-old sea creature has revealed the earliest known evidence of the structures that eventually became spiders’ fangs。 Hidden inside the fossil were pincerlike limbs and preserved soft tissues that help explain how the ancestors of spiders and scorpions evolved into formidable hunters
A group of brain cells called orexin neurons appears to help us keep working when reaching a reward becomes increasingly difficult。 Blocking their activity weakened motivation in rats, pointing to a possible new target for understanding why people sometimes struggle to sustain goal-directed behavior
Disney is interested in "price-sensitive" streaming customers
Weight loss is not simply a test of willpower。 The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss。 This biological “memory” helps explain why many people regain weight after dieting and why m
The state attorney general said in an antitrust lawsuit filed on Tuesday that the company was abusing its market power to keep its delivery costs low
A new study shows how the big cats cause deer to move away from roads and deeper into the forest, where they pose less of a hazard to motorists
Company noted for building quantum annealers now also making gate-based hardware
Scientists have uncovered a surprising way that “jumping genes” may move between species and speed up evolution。 While these mobile genetic elements were thought to travel mainly inside viruses or plasmids, researchers found circular intron RNA from a tiny predatory bacterium inside the dead cells of another microorganism。 Because the RNA forms a s
Federal officials will update the outbreak sometime "this week," a spokesperson said
The UK's AI Safety Institute said recent behaviour from Anthropic and OpenAI models was malicious and unprecedented
Minutes after four top researchers said they were leaving, Google said that Demis Hassabis, the Nobel-winning scientist who led the company’s A。 lab, was stepping into a new job
25 billion program restored, but judge ruled race provision unconstitutional
Hi HN, this is Shailendra and Karan here。 We are building a fast and safe way for coding agents to debug issues live in production。When prod breaks, it lets Cursor, Claude, and others drop virtual breakpoints or probes safely in your running code, and extract the exact variable values that logs don’t have
Homeland Security told immigrants that leaving the US would wipe out fines it claims they owe。 Now it wants private investigators to find them in their home countries and collect
When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces。 New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion。 This acceleration may do far more
Mugshawtys and similar pages often frame mugshots as thirst traps。 The women featured are mocked and are sometimes sexually harassed in a form of public shaming
In African tech hubs, developers are picking China’s cheap, freely available artificial intelligence models over more powerful U
Xbox consoles now cost significantly more in the UK, with one model increasing in price by 43%
