A brief update is given on a number of ongoing O..nu.. ..beta beta..-decay experiments. Progress is reported in background reduction, limits are given on the various modes of decay, and projections of potential sensitivity are made in some cases. In particular, a new result from the PNL-USC O..nu.. ..beta beta.. decay experiment yields a half-life of (3.2/sup +2.2//sub -1.2/) x 10/sup 21/ y (1sigma) for decay with the emission of a majoron. While a positive result is still observed, it is now statistically less significant. A new recently deep-mined Ge to decrease background cosmogenic radioactivity.
