Chalmers engineers built a pulse-driven qubit amplifier that's ten times more efficient, stays cool, and safeguards quantum states--key for bigger, better quantum machines.

Washington University researchers found that raising a molecule called ApoM helps eye cells sweep away harmful cholesterol deposits linked to age-related macular degeneration, potentially preventing vision loss, and the same trick might aid failing . ...

Lichen from the Mojave Desert has stunned scientists by surviving months of lethal UVC radiation, suggesting life could exist on distant planets orbiting volatile stars. The secret? A microscopic "sunscreen" layer that protects their vital cells- ...

Wildfires don't just leave behind scorched earth--they leave a toxic legacy in Western rivers that can linger for nearly a decade. A sweeping new study analyzed over 100,000 water samples from more than 500 U.S. watersheds and revealed that ...

Major depressive disorder affects hundreds of millions worldwide, but a key to understanding its origins may lie in the brain's immune system. New findings spotlight astrocytes--previously overshadowed by microglia--as major players in ...

UC San Diego scientists have created a gene therapy that goes beyond masking Alzheimer's symptoms--it may actually restore brain function. In mice, the treatment protected memory and altered diseased brain cells to behave more like healthy ones.

Over 300 million years ago, Earth experienced powerful bursts of carbon dioxide from natural sources--like massive volcanic eruptions--that triggered dramatic drops in ocean oxygen levels. These ancient "carbon burps" led to dangerous periods of ...
