sounds legit -Scientists using thousands or even millions of pc's to compute some biological stuff that sounds really complicated.....

"Dr. Vijay Pande, a professor of chemistry and structural biology at Stanford, saw the potential for thousands of desktop computers to calculate tiny portions of a folding sequence. He wrote algorithms for Mac, Windows and Linux computers, and worked with distributed-computing entrepreneur Adam Beberg to integrate his code into an application dubbed Folding@home."
