Ultrasensitive experiments on trapped antiprotons provide a window onto possible differences between matter and antimatter. Now they could also shed light on the identity of dark matter.
Three physicists wanted to calculate how neutrinos change. They ended up discovering an unexpected relationship between some of the most ubiquitous objects in math.
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.
Nicole Ackerman thought she would always be a particle physicist—until a newfound interest in biology drew her toward medical imaging. Her research on Cherenkov radiation, the blue glow from charged particles outracing light, could aid development of cancer treatments.
