Electrons are really, really round. A new measurement confirms the subatomic particle’s spherical shape to a record level of exactness, physicists report in the July 7 Science. That near-perfect ...

The Muon g-2 ring sits in its detector hall amidst electronics racks, the muon beamline, and other equipment. This impressive experiment operates at negative 450 degrees Fahrenheit and studies the ...

In classical physics, a vacuum is a total void—a true manifestation of nothingness. But quantum physics says that empty space isn’t really empty. Instead, it’s buzzing with “virtual” particles ...

The particle in question, known as a sterile neutrino, was supposed to only interact with gravity and have zero interactions ...

At a lab in Batavia, Illinois, 200 physicists from seven countries have possibly made the biggest scientific discovery in decades. It involves a subatomic particle called a Muon. It's kind of like an ...
