Physicists build bigger 'bottles' of antimatter to unlock nature's secrets
Once regarded as the stuff of science fiction, antimatter -- the mirror image of the ordinary matter in our observable universe -- is now the focus of laboratory studies around the world.

While physicists routinely produce antimatter with radioisotopes and particle colliders, cooling these antiparticles and containing them for any length of time is another story. Once antimatter comes into contact with ordinary matter it "annihilates" -- or disappears in a flash of gamma radiation.
