The ALPHA experiment at CERN last year reported trapping 38 antihydrogen atoms for 0.1 seconds each. They've gotten better. In a run late last year, they captured more than 100 for up to 1,000 seconds each, enough to start long-awaited experiments to determine the energy levels of antiatoms. They also plan gravitational experiments to see if matter and antimatter have the same properties.
