Antimatter Matters:
Physicists Create Antimatter Briefly
Physicists at Cern have created antimatter and held onto it for several minutes.
The ALPHA (Antihydrogen Laser PHysics Apparatus) experiment represents a breakthrough in the study of antimatter.
From Scientific American:
The lifetime of antihydrogen in the ALPHA trap is probably sufficient to begin those studies. "We think we're in a position to start measuring something," says ALPHA spokesperson Jeffrey Hangst of Aarhus University in Denmark. Initial studies will involve irradiating the anti-atoms with microwaves to try to engage them in a resonant interaction, flipping their spin like a compass needle swinging from north to south.
