(AP) -- The Space Sciences Laboratory at the University of California, Berkeley, has signed up more than 1 million volunteers worldwide in a search for extraterrestrial intelligence. They've found no aliens yet, but they have at least turned up one missing laptop.

Annoyed - and alarmed that someone could delete the screenplays and novels that his wife, Melinda Kimberly, was writing - Melin monitored the SETI(at)home database to see if the stolen laptop would "talk" to the Berkeley servers. Indeed, the laptop checked in three times within a week, and Melin sent the IP addresses to the Minneapolis Police Department.
