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

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

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

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

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

Puck’s Matthew Belloni says AI has quietly become part of everyday filmmaking。 The battle now isn’t whether Hollywood will use the technology—it’s who controls what’ll come next

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

Hidden moon ice may reveal itself through the way it bends and reflects vibrations from moonquakes。 The technique could help astronauts locate vital water supplies and uncover clues about the origins of Earth’s oceans

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

Clean your house without the constraint of a power cord, thanks to these stick vacuums

ESPN unveiled an “AI tells detection” tool during broadcasts of the 2026 World Series of Poker。 Is it a neat computer-powered party trick, or a real threat to poker’s future

The second stage of a Falcon 9 rocket, which sent two private landers to the moon last year, will collide with the moon early Wednesday morning

Billions of dollars are being poured into a new wave of AI technology。 But will it pay off

Snapchat, YouTube, LinkedIn, and Substack are trying to combat the proliferation of fake AI content

Federal officials will update the outbreak sometime "this week," a spokesperson said

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

Over the years, tech workers have proudly worn nerdy company-branded gear。 But this generation of hot companies is getting fancy with its merch

Indian strawberry farmers rely on varieties imported from the US and Europe, but that could change
