Scientists have developed a stem cell "gun" that can be used to treat severe burn victims with their own stem cells. This video contains some pretty nasty looking burn images so if you're faint of heart you might want to look away. http://www.youtube.com/watch?v=eXO_ApjKPaI&feature=player_embedded
I'm not squeamish a bit, but then, I used to do medicine as a job. (When I was in medical school I spent 6 weeks studying at Seattle's Harborview Burn Unit. I used to get hungry during surgery because the cautery cooked the tissues and smelled like BBQ.) That's a really cool idea though. It's a big improvement over some of the techniques we were using back in the late 1970's.
