A team of scientists in Europe has trapped and held atoms of antihydrogen, hydrogen’s antimatter twin, for 1,000 seconds, almost 6,000 times longer than in previous experiments. With their improved antimatter bottle, reported online June 5 in Nature Physics, scientists at the European particle physics laboratory CERN near Geneva may soon be able to test several theories about antimatter. General relativity, for instance, predicts that gravity should have the same effect on antimatter as on matter. The standard model of particle physics suggests that the light given off by antihydrogen should be the same as that given off by hydrogen. —Devin Powell
