Just spotted a story on /. about a new project called Stardust@home. This has been set up at Berkeley to look for dust particles in the returning sample from the Stardust mission (15 Jan). Probably not BOINC and I doubt you get any points - hey you even have to pass an exam to be allowed to participate! But looks like fun and big kudos if you find a particle... Pre-register to avaoid disappointment!
