Possibly the greatest tribute to veterans...
This blew me away: http://www.cnn.com/2008/HEALTH/05/26/regrowing.body.parts/index.html
Last week in an operating room in Texas, a wounded American soldier underwent a history-making procedure that could help him regrow the finger that was lost to a bomb attack in Baghdad last year.
Army Sgt. Shiloh Harris' doctors applied specially formulated powder to what's left of the finger in an effort to do for wounded soldiers what salamanders can do naturally: replace missing body parts.
The article is worth reading. Even if it doesn't work Harris is a hero, yet again, for taking on the unknown risks of this experimental treatment.
