Scientists have long sought to explain how fish can sense the direction of sound, given the challenges that hearing underwater poses. An experimental study testing a variety of models now provides ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

UNIVERSITY PARK, Pa. — For the first time, scientists have observed a collection of particles, also known as a quasiparticle, that's massless when moving one direction but has mass in the other ...

Since the start of the 20th century, physicists have discovered a veritable zoo of subatomic particles. Matter can be both wave and particle. If you take the particle route, these subatomic particles ...

A particle that changes its behavior depending on the direction it takes: in one direction, it glides effortlessly as if it weighs nothing. In the other, it seems to have weight. This might sound like ...
