It's getting bitterly cold and unnaturally crowded in atom traps.

A year ago, a group of researchers at the National Institute of Standards and Technology in Gaithersburg, Md., chilled cesium atoms to 700 nanokelvins (SN: 9/10/94, p.175). Now, Eric A. Cornell and his coworkers at the Joint Institute for Laboratory Astrophysics (JILA) at the National Institute of Standards and Technology and the University of Colorado in Boulder have brought a clump of neutral atoms even clos...
