Humans are leaving behind a 'frozen signature' of microbes on Mount Everest

University of Colorado Boulder-led research: Humans are leaving behind a 'frozen signature' of microbes on Mount Everest.

Microorganisms are everywhere, even in the air, and can easily blow around and land some distance away from nearby camps or trails.

Researchers found microbial DNA for some organisms heavily associated with humans, including Staphylococcus, a dominant genus in the human mouth.
