After years of confusion, a new study confirms the proton is tinier than once thought. That enables a test of the standard model of particle physics.

For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based ...

We describe electricity as a flow, but that’s not what happens in a typical wire. Physicists have begun to induce electrons to act like fluids, an effort that could illuminate new ways of thinking ...

Neutrinos are very small, neutral subatomic particles that rarely interact with ordinary matter and are thus sometimes ...

Before the RHIC shut down, it was the only operational particle collider in the U.S. and one of two heavy-ion colliders in the world, the other being the Large Hadron Collider at CERN in Switzerland.
