100 mystery sounds under review for signs of extraterrestrial life

Over 11 years, citizen scientists collected billions of data signals for the SETI@home project. Breakthroughs, discoveries, and DIY tips sent six days a week. After reviewing almost 30 years of signals, University of California Berkeley researchers have identified 100 mysterious, deep-space radio blips they want to review for signs of extraterrestrial life . And they couldn't have done it without 11 years of volunteer work from millions of PC owners around the world. Even with today's advanced computers, the world's most complex data problems can't be solved by a single machine.
