Physicists have nailed a fiendishly difficult measurement — the mass of the fundamental particle the W boson. The result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with ...

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 ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their ...

Devices could eliminate the strong magnetic fields currently required to define the standard unit of resistance ...

Physics at the smallest scales is a challenge of observation: Particles are often fleeting, and the forces that govern their behavior are nearly imperceptible. But now, by exploiting decades-old data ...
