In this issue (1), a group from the University of Texas reports producing rubidium dimers that are essentially at rest, by assembling them from ultracold Rb atoms in an atomic Bose-Einstein condensate (BEC). The report (see page 1016) contains several important accomplishments: the first observation of molecule formation a BEC, an ultraprecise measurement of a molecular binding energy, and the first measurement of the interaction energy between a condensate and a molecule.
