Actually this is not new. You may help fighting cancer, but remember - you help finding a cure which will be patented and make big amounts of money for the company to which you graciously give away you computing time. Actually you have no control what kind of calculation are made on your computer, read the fineprint to make sure you DO calculate for a cancer project fulltime and don't calculate nuclear weapons inbetween. Just my two cents. Just wanted to show the whole cake, not just the sugar.
