Hi there. Been BOINCing for about 4 years, and involved in almost all the current BOINC projects, and I like to think that my humble returns make a difference to the greater good!
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
