After a decade of meticulous measurements, scientists announced Thursday that a fundamental particle -- the W boson -- has a significantly greater mass than theorized, shaking the foundations of our ...

There was a bump in the middle of the night. On June 14, 2012, Johns Hopkins physics and astronomy professor Andrei Gritsan analyzed data in a small meeting room at the CERN in Switzerland. He worked ...

Scientists at the University of Illinois Urbana-Champaign have confirmed the existence of a massless particle, long theorized ...

A shock measurement of the mass of a fundamental particle called the W boson ignited the physics world in April, as it appeared to flout the standard model of particle physics. Hundreds of papers have ...

Every few years, scientists take a step back to take a broader look at their field and determine what questions are most pressing—and what tools they will need to answer those questions. This year the ...
