A distant star system with four super-sized gas giants has revealed a surprise. Thanks to JWST's powerful vision, astronomers detected sulfur in their atmospheres -- a chemical clue that they formed like Jupiter, by slowly building solid cores. That ...

A long-standing mystery in spintronics has just been shaken up. A strange electrical effect called unusual magnetoresistance shows up almost everywhere scientists look--even in systems where the leading explanation, spin Hall magnetoresistance, ...

Researchers at the University of Michigan have created an AI system that can interpret brain MRI scans in just seconds, accurately identifying a wide range of neurological conditions and determining which cases need urgent care. Trained on hundreds . ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying on any external clock. By tracking subtle changes . ...

Baker's yeast isn't just useful in the kitchen -- it may also be built for space. Researchers found that yeast cells can survive intense shock waves and toxic chemicals similar to those on Mars. The cells protect themselves by forming special stress ...

Scientists at the University of Warwick have cracked a long-standing problem in air pollution science: how to predict the movement of irregularly shaped nanoparticles as they drift through the air we breathe. These tiny particles -- from soot and ...

A colossal ancient impact may have reshaped the Moon far more deeply than scientists once realized. By analyzing rare lunar rocks brought back by China's Chang'e-6 mission from the Moon's largest crater, researchers found unusual chemical ...

Physicists at Heidelberg University have developed a new theory that finally unites two long-standing and seemingly incompatible views of how exotic particles behave inside quantum matter. In some cases, an impurity moves through a sea of particles . ...

Voyager 2's flyby of Uranus in 1986 recorded radiation levels so extreme they baffled scientists for nearly 40 years. New research suggests the spacecraft caught Uranus during a rare solar wind event that flooded the planet's radiation belts with ...

Astronomers propose that an ultra-dense clump of exotic dark matter could be masquerading as the powerful object thought to anchor our galaxy, explaining both the blistering speeds of stars near the center and the slower, graceful rotation of ...
