A: Folding at home is a means of us taking our unused computer cycles to help Stanford University academics in medical research. The scientific bits can be found here: http://www.stanford.edu/group/pandegroup/science.html but simply put we will simulate the behavior of proteins and hence hopefully understand them.
Basically contributing to finding a cure to Cancer and Alzheimers by running a small app that uses unused CPU cycles. I think MyADSL should set up a team for folding. Lots of forums have done it and, like I said it's for a great cause.
Im gonna put the client on my portable HDD and leave it running while I do pracs and stuff at the varsity labs as well. I hope we can get a nice big South African folding community going. Plus with the PS3s folding client there should be a whole lot more folding going on in SA.
