F@H or "Folding At Home" is the process of molecular dissemination of protein forms. This illustrates the process by which proteins "fold" and become their finalized entities. Somewhere along the process, improper replication of protein models can form.. and are responsible for types of cancer and other maladies of mankind.
By joining the program, your home computer receives a small protein molecule and "folds" it during a background process.. not causing any noted slowing or interference with your normal computer operation.
Here is the link to the Stanford University site.. http://folding.stanford.edu/
This is a world-wide effort to discover why and how proteins fold improperly and what can be done to prevent that.
F@H.. to solve mankind's maladies.. in our lifetimes!
