New study of Otzi the iceman identifies surviving microbes

Otzi the Iceman, the mummified Copper Age man discovered in the Italian Alps in 1991, has been dead for more than 5,000 years. But a new study has found multiple types of microbes that survived the extreme cold of the glacier that preserved his body. Scientist Frank Maixner told The World's Host Carolyn Beeler that some of these microbes came from the environment, while others were part of his gut microbiome, which could offer new insights for future medical research.
