In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.
Want to play with subatomic particles? You could go to work at Brookhaven National Laboratory's Relativistic Heavy Ion Collider, RHIC—or you could play a new card game.
Close to the Canadian border, near an area known as the Boundary Waters, scientists are building an experiment to discover how neutrino masses stack up. They aim to get closer to understanding how matter came to dominate antimatter in our universe.
Neutrinos zip straight through the Earth, while rarely leaving a trace. Yet these particles may hold answers to many of the key questions of 21st century particle physics.
