Story summary

Researchers led by Mohamed Sarhan revived cold-adapted yeast from Ötzi the Iceman’s 5,300-year-old remains.
The revived yeast metabolizes phenol, suggesting it could help clean chemical contamination.
After storing the yeast and an initial baking failure, the team produced a good sourdough loaf three months later.
Four strains thriving at Antarctic-like temperatures were found in the mummy’s gut, skin and meltwater, prompting scientists to test uses in brewing and medical research.
