Protein Folding

  • Folding@Home Distributed Computing Project –  “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 simulat timescales thousands to millions of times longer than previously achieved.”  This site provides information about protein folding and its importance and provides software for personal computers that allows individuals to participate in the protein folding computing process.



  • Promenade Round the Cochlea, a delightful educational site with excellent graphics on the physiology and biophysics of the ear; generated and maintained by the University of Montpellier.
