Yet another shameless plug, but for a good cause.
For those not in the know, Folding@Home is a distributed computing project which studies protein folding, misfolding, aggregation, and related diseases. We use novel computational methods and large scale distributed computing, to simulate timescales thousands to millions of times longer than previously achieved. This has allowed us to simulate folding for the first time, and to now direct our approach to examine folding related disease. (I just pulled this from their site)
If that doesn't help, well then your probably shouldn't help them.
Anyway, it is a great idea, assuming you have a decent comp. Also, if you would be so kind, if you do do it, join team 33258. This is my Motherboards.org team. We want/need your help, maybe. It would be a good thing. Remember team 33258!
