Using CERN's Super Proton Synchrotron, researchers generated plasma fireballs to simulate blazar jets. The beams stayed stable, suggesting plasma instabilities aren't responsible for missing gamma rays. Instead, the data strengthens the idea of ...

Researchers are exploring MXenes, 2D materials that could transform air into ammonia for cleaner fertilizers and fuels. Their atomic structures can be tuned to optimize performance, making them promising alternatives to expensive catalysts.

A new theory claims dark matter and dark energy don't exist -- they're just side effects of the universe's changing forces. By rethinking gravity and cosmic timelines, it could rewrite our understanding of space and time itself.

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the strange chemical fingerprints found in ancient ...

Evidence now suggests the universe's expansion has started to slow, not speed up. The findings imply dark energy is weakening, marking a possible revolution in cosmology.

Astronomers have discovered that aging stars may be devouring their closest giant planets as they swell into red giants. Using NASA's TESS telescope to study nearly half a million stars, scientists found far fewer close-orbiting planets around older, ...

USC researchers built artificial neurons that replicate real brain processes using ion-based diffusive memristors. These devices emulate how neurons use chemicals to transmit and process signals, offering massive energy and size advantages. The ...

A new copper-magnesium-iron catalyst transforms CO2 into CO at low temperatures with record-breaking efficiency and stability. The discovery paves the way for affordable, scalable production of carbon-neutral synthetic fuels.

Engineers at the University of Delaware have uncovered a way to bridge magnetism and electricity through magnons--tiny waves that carry information without electrical current. These magnetic waves can generate measurable electric signals within ...

Researchers using new simulations suggest that the Milky Way's past collisions may have reshaped its dark matter core. This distorted structure could naturally explain the puzzling gamma-ray glow long thought to come from pulsars. The findings revive ...
