Well I have a love for physics, chem and space science (not so much bio). I saw seti@home on the home page of bing (yes I use bing but its literally the same as google I just like the cool pictures) and thought it would be cool to help out. What can I say...
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.
