Wow, they have created a whole healthy mouse (a couple, actually) from mere mouse skin cells, and without using those cancer-causing genes to program the adult cell back to embryonic state! This is a feat....I think this science will move really fast now because of the implications for so many diseases, woo-hoo! Here's the link:

Also, in Jsapan, they created a functioning mouse tooth, it implanted, can feel pain, chew, the whole "bit" (lol). This science is really moving, it is so encouraging.
