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
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
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

Federal officials will update the outbreak sometime "this week," a spokesperson said
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
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
25 billion program restored, but judge ruled race provision unconstitutional
Clement Delangue said he didn't want cyber attacks on other companies to become "normalised"
Nobody likes getting a swab shoved up their nose。 A startup in Japan has developed a much less intrusive system
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
Inside the 81-year-old billionaire’s risky, debt-fueled scramble to transform his data empire into an A。 juggernaut
Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time inside。 Researchers tested whether this was merely a misleading feature of the light pulse by making extremely weak measurements of the atoms。 Surprisingly, the atoms confirmed the same negative dwell time
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
Billions of dollars are being poured into a new wave of AI technology。 But will it pay off
Jeff Dean, who for years was one of Google’s most important executives, is leading the new artificial intelligence company with the backing of Google
