Scientists conducted microbial DNA sampling at a Yellowstone National Park hot spring for a study sponsored by DOE’s Biological and Environmental Research program, the National Science Foundation and NASA.

Oak Ridge National Laboratory scientists studied hot springs on different continents and found similarities in how some microbes adapted despite their geographic diversity. The findings yield clues to the evolution of life and whether some of the hardiest microbes may be harnessed for biotechnology., was the first of its kind to sample hot springs on three continents with water temperatures above 65 degrees in the United States, Iceland, and Japan.
“We found common microbes, but also diversity as the microorganisms adapted to local conditions,” Podar said. The scientists theorize that tectonic conditions and geology of the hot springs are at play, providing new insights into how life and the Earth have co-evolvedReference: “Tectonic and geological setting influence hot spring microbiology” by Daniel R.
