To understand why the universe is made of matter and not antimatter, physicists are looking for a tiny signal in the electron

The Short-Baseline Neutrino Program will try to determine once and for all whether sterile neutrinos are real

A major report plotting the future of U.S. particle physics calls for cuts to the beleaguered DUNE project, advocates a “muon shot” for a next-generation collider and recommends a new survey of the universe’s oldest observable light

Pierre Agostini, Ferenc Krausz, and Anne L’Huillier split the award for their ability to picture nature in a billionth of a billionth of a second

In theory, physicists knew that antimatter should behave just like matter under gravity’s pull. But until now, no one had ever seen it happen

Letters between Lise Meitner and the chemist Otto Hahn reveal how she struggled with Hahn's failure to credit her work and condemn the Nazi atrocities

A pilot program for high schoolers offers a blueprint in getting students involved in cutting-edge particle physics research

Lise Meitner, an Austrian-born Jewish physicist, never received the Nobel Prize she deserved for her pioneering work on nuclear fission

The long-awaited discovery of oxygen 28 might prompt physicists to revamp theories of how atomic nuclei are structured

After years spent languishing in obscurity, proposals for a muon collider are regaining momentum among particle physicists

Physicists are on an ever urgent quest to find a fuller understanding of what makes the cosmos tick, which they call a theory of everything
