Physicists at the UK’s Central Laser Facility have recorded the first observation of quantum radiation reaction, detecting how electrons lose energy in ways that classical physics cannot explain when ...

Seemingly random charging of identical materials depends on the carbonaceous molecules stuck to their surfaces ...

When particles in volcanic ash cloud rub together, some pick up positive charge and others negative – now physicists have ...

Two microscopic grains collide and produce a tiny spark. This phenomenon may have provided the energy to kick off life on Earth. But if these solid particles have the same composition, what factor ...

The familiar phenomenon has puzzled researchers for centuries, but experiments are finally making sense of its unruly behaviours.
