Filled with a noxious brew of copper, cadmium and arsenic, with a pH rivaling that of sulfuric acid, Montana’s Berkeley Pit seems inhospitable to life.

These extreme environments induce microbes to synthesize potent, never-before-seen molecules that could find uses in human medicine, according to an article in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society.
