A decadelong experiment produced the most accurate measurement yet of the mass of W bosons. These particles are responsible for the weak force, and the result is more evidence for undiscovered physics.
Experiments at the Large Hadron Collider in Europe, like the ATLAS calorimeter seen here, are providing more accurate measurements of fundamental particles.
Physicists know a lot about the most fundamental properties of the universe, but they certainly don’t know everything. 2021 was a big year for physics – what was learned and what’s coming next?

A new result from the MicroBooNE neutrino experiment has dashed hopes for a neat resolution to several puzzles for physicists.
There’s more going on in the universe than we know.
Particle physicists might be on the brink of a major breakthrough.
Cern scientists have successfully cooled antimatter with a laser for the first time.
Laser-cooling enables new measurements that could explain why antimatter is so scarce in our universe.
