Current models of physics dictate there should be as much antimatter in the universe as matter, but there isn't. Work at the world's largest particle collider has come a step closer to explaining why.

In a first, CERN physicists succeeded in observing matter-antimatter imbalance in baryons, fundamental particles that make up ...
