This spray-on powder can stop life-threatening bleeding in 1 second
A new spray-on powder developed by KAIST can stop life-threatening bleeding in about one second by instantly forming a strong gel over a wound. It works on deep and irregular injuries where conventional hemostatic products often struggle and remains ef…
Climate scientist who “proved” humanity is warming Earth says government report got it wrong
A pioneering climate scientist is challenging a U.S. government report that cited his research while reaching what he says is the exact opposite conclusion. Benjamin Santer and his colleagues say decades of satellite data clearly reveal the atmospheric…
Tiny magnetic waves could unlock quantum computers the size of a penny
A major breakthrough in quantum technology has turned magnons, tiny magnetic waves once considered too short-lived for practical use, into promising carriers of quantum information. Researchers extended their lifetime by nearly 100 times, reaching up t…
How asteroids may have sparked life on Earth
Ancient asteroid impacts may have done more than reshape Earth’s surface—they could have helped spark life itself. New computer models show the collisions created enormous underground hydrothermal systems by cracking the planet’s crust and allowing hot…
390 gravitational wave detections reveal hidden population of black holes
Astronomers have released the largest gravitational wave catalog ever, revealing 161 new black hole collisions and pushing the total number of detections to 390. Among the highlights are the clearest gravitational wave signal ever recorded, the most ac…
Scientists reveal what really happens when water is trapped in tiny spaces
A decades-old puzzle about water has finally been unraveled. Researchers found that water trapped in tiny nanoscale spaces is not inherently more reactive. Instead, the intense pressures created inside these microscopic gaps explain most of the effect,…
Scientists create quantum sound device that could transform communications
A new quantum device can generate precisely controlled bursts of sound-like particles, or phonons, by forcing electrons through an ultra-thin crystal at extremely low temperatures. The surprising behavior pushes beyond the limits predicted by current t…
Great ape laughter reveals a hidden origin of human speech
The rhythm of human laughter appears to have deep evolutionary roots shared with chimpanzees, bonobos, gorillas, and orangutans. That ancient pattern may offer one of the clearest clues yet to how the vocal control needed for human speech gradually evo…
