Study suggests "the bias is real but socially constructed, rather than grounded in how women actually sound
Judge orders Apple to give Musk internal messages discussing secretive ChatGPT deal
A newly discovered meteor stream may be the smoking gun of an asteroid slowly disintegrating under the Sun’s intense heat。 Scientists say these fiery streaks across the night sky could reveal hidden near-Earth asteroids that telescopes struggle to detect
Scientists studying mysterious ultra-powerful cosmic rays have uncovered a surprising hidden pattern that could finally help explain where these particles come from。 Using the DAMPE space telescope, researchers found that cosmic ray particles—from tiny protons to heavy iron nuclei—all begin fading away more sharply at the exact same point, hinting
A powerful new electromagnetic thruster has taken a major step forward after a successful high-energy test at NASA’s Jet Propulsion Laboratory。 Fueled by lithium vapor and driven by intense magnetic forces, the experimental engine reached record-breaking power levels—far beyond anything currently used in space。 Glowing hotter than molten lava and f
Vaccines may be training a part of our immune system long thought to be untrainable
A new quantum-inspired algorithm has cracked a problem so massive that conventional supercomputers struggle to even approach it。 Researchers used the method to simulate extraordinarily complex quantum materials known as quasicrystals, opening the door to powerful new quantum devices and ultra-efficient electronics。 The work could help scientists de
“This is a public trust and transparency issue
The vacuum giveth, the vacuum taketh, but the vacuum doesn’t let you taketh
A medieval monk may have beaten Edmond Halley to one of astronomy’s greatest discoveries by nearly 700 years。 Researchers say Eilmer of Malmesbury recognized that the blazing comet seen in 1066 was the same one he had witnessed in 989。 At the time, comets were viewed as terrifying omens tied to war and royal deaths, adding even more drama to the fa
Physicists may have just cracked open a hidden side of the quantum world。 For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in a one-dimensional system。 Even more exciting, these strange particles m
A customized mid-motor and Shimano's new Cues components are a winning combination
NASA’s Curiosity rover had an unexpectedly stubborn Mars souvenir after drilling into a rock nicknamed “Atacama” — the entire chunk ripped loose from the ground and stayed stuck to the rover’s drill。 Engineers watched as Curiosity shook, vibrated, tilted, and spun the drill over several days in an effort to free the rock, while cameras captured the
One little mystery—solved
"We have no grand plan," says Anthropic's Cat Wu—but that's by design
The little pauses, “ums,” and moments when you struggle to find the right word may reveal far more about your brain than anyone realized。 Researchers discovered that everyday speech patterns are closely tied to executive function — the mental system that powers memory, planning, focus, and flexible thinking。 By using AI to analyze natural conversat
NASA’s Psyche spacecraft is about to pull off a dramatic close flyby of Mars, skimming just 2,800 miles above the planet to get a powerful gravitational boost on its journey to the mysterious metal-rich asteroid Psyche。 The maneuver will save propellant while giving mission scientists a rare chance to test and calibrate the spacecraft’s instruments
Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe。 A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all, a trait usually seen only in much older, evolved galaxies。 This challenges current theories that young galaxies
NASA is testing a next-generation space computer chip that could give spacecraft the ability to operate far more independently in deep space。 The radiation-hardened processor is showing performance levels hundreds of times beyond current spaceflight computers while surviving punishing tests designed to mimic the harsh conditions of space。 The techn
Cumberland, B。 is reimagining its coal mining past as a clean energy opportunity。 Water trapped in abandoned mine tunnels could be used in a geothermal system to heat and cool buildings efficiently and with minimal emissions
