Facing a growing drone threat, the Pentagon is poised to sign a first-of-its-kind contract for “Enduring High Energy Lasers”—and make directed energy weapons an official part of the Army’s kit
The UK's AI Safety Institute said recent behaviour from Anthropic and OpenAI models was malicious and unprecedented
A Louisiana launch site would offer several significant advantages
I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy。I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos
DNA traces in the Shroud of Turin reveal a remarkable mixture of human lineages, microbes, plants, animals, and coral accumulated through centuries of handling and travel。 The findings do not prove its age or authenticity, but they expose a hidden biological history preserved in the famous cloth
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 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
The deal takes the maker of titles including The Sims and EA FC into private ownership - and loads it with debt
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected。 An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands。 That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it

From wired to wireless to ultralight, we've tested dozens of gaming mice to find the best for work, your next MMO, and everything in between
Vanderbilt researchers created the first selective compound designed to inhibit TAOK-1, a poorly understood protein connected to Alzheimer’s disease。 They also discovered a second compound that activates the entire TAOK protein family, offering scientists an unexpected new research tool。 Together, the compounds could reveal hidden disease mechanism
Researchers have found a way to build much larger “twisted” oxide materials while precisely controlling how their atomic layers line up。 Because these materials can be made over large areas and transferred onto different surfaces, the technique could help turn twistronics from a laboratory curiosity into a practical platform for next-generation ele
Federal officials will update the outbreak sometime "this week," a spokesperson said
