Adding onto Ani's post a couple back, I was watching TV (like I never do at Stanford) and saw Irv Weissman from Stanford's Immunology department on TV talking about the breakthrough in stem cells. The news anchor said that this development is as big as the Wright Brothers (questionable?). I went onto their website and found this cool video (I'm a visual learner) and supporting article which presents some views on this stem cell development.
Have fun! Happy Turkey Day!
