http://www.washingtonpost.com/wp-dyn/content/article/2006/04/14/AR2006041401387.html I saw this article and this could be a major change in the world if it turns out successful. We may never be able to get rid of maleria, the common cold and a many other diseases. I don't think this would eliminate the HIV problem either, but it would defiently slow epidemic. We have come a long way since the discovery of Patient Zero, back in the early 80's.
