A smiling prehistoric man and a rocket lifting off to the heavens. First discovered in Italy's Ötztal Alps in September 1991, Ötzi was a prehistoric man who died, likely by murder, some 5,300 years ago before being mummified naturally inside glacier ice. But bad news for Ötzi was good news for four strains of cold-adapted glacier yeasts, which infiltrated his body shortly after his death and may still be active today.
