Just came across this interesting thing : www.fold.it . Have just downloaded there arena today . It promises that you can make a difference to protein folding world or atleast learn about protein folding i would think . I am still to start playing . Will share experiences once i have played it a bit . Meanwhile you can check it out for yourself .
Please don’t close this question thinking it is not related to computing . It is COMPUTATIONAL in nature as far as i have understood till now .
