UT research finds life can persist in a cold, dark world. A UT microbiology assistant professor was part of a team that examined waters and sediments from a shallow lake deep beneath the Antarctic ice sheet and found the extreme environment supports microbial ecosystems.
The National Science Foundation-funded research by Jill Mikucki and her colleagues has implications for life in other extreme environments, both on Earth and in the solar system. The findings are published in the current edition of the science journal Nature.
Analysis of samples taken from Subglacial Lake Whillans, which is under 800 meters of ice, shows that the lake “supports a metabolically active and…diverse ecosystem that functions in the dark at subzero temperatures,” according to the authors.
