Summary

Two rival teams are hot on the trail of antihydrogen, the antimatter doppelgänger of the simplest element, hydrogen. Within a month, each announced that it had created tens of thousands of "antiatoms" cold and slow-moving enough to be studied. The results marked the first surge forward in a race to measure antihydrogen's spectrum--a discovery that could rattle the foundations of physics and will likely net a Nobel Prize for whichever team gets there first. Not surprisingly, the competition is intense.
