At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter.

At Brookhaven National Laboratory on Long Island, the Relativistic Heavy Ion Collider has powered down for the last time, ending operations at the only particle collider still running in the United ...

A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without waiting until 2070 for a new collider.

When the universe first burst into being, all of space was a cosmic cauldron filled with a roiling, fiery liquid of ...

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.

Something odd is happening deep inside the data streams from CERN’s Large Hadron Collider. A set of “forbidden” patterns in how unstable particles decay, combined with rare Higgs events and a ...

CERN's Large Hadron Collider now heats thousands of French homes with waste heat, turning particle physics research into practical energy savings.

The Relativistic Heavy Ion Collider , the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set ...

In a collider ring on Long Island, physicists have turned a long standing thought experiment into hard data, watching new ...

Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated ...

When trying to answer questions as deep as “what makes up the universe,” advance planning is key. On June 11, the National Academies of Science, Engineering and Medicine announced the result of a ...

The University of California, Santa Cruz, will host an international gathering of particle physicists this week to discuss the development of a next-generation international particle accelerator ...
