Coldest, Driest, Saltiest Antarctic Soils Might Be Inhospitable To Life

Science | The Biological World

Some Antarctic soils might be the only environments on Earth microbes can't colonize, a finding that goes against scientists' expectations of our planet's habitability. Most scientists assume microbes can inhabit every environment on Earth, given enough time, but new research finds that some of the coldest, saltiest, and driest soils in the Transantarctic Mountains show no signs of viable microbial life.
