800 meters beneath Antarctic ice sheet, subglacial lake holds viable microbial ecosystems
National Science Foundation
In a finding that has implications for life in other extreme environments, both on Earth and elsewhere in the solar system, researchers funded by the National Science Foundation published a paper confirming that the waters and sediments of a lake that lies 2,600 feet beneath the surface of the West Antarctic ice sheet support "viable microbial ecosystems."

Sunlight, not microbes, key to carbon dioxide in Arctic
Oregon State University via ScienceDaily
The vast reservoir of carbon stored in Arctic permafrost is gradually being converted to carbon dioxide after entering the freshwater system in a process thought to be controlled largely by microbial activity. However, researchers say that sunlight and not bacteria is the key to triggering the production of CO2 from material released by Arctic soils.

Hot-spring bacteria reveal ability to use far-red light for photosynthesis
Penn State
Bacteria growing in far-red light use a previously unknown process for harvesting energy and producing oxygen from sunlight, a research team led by a Penn State scientist has discovered. The discovery lays the foundation for further research aimed at improving plant growth, harvesting energy from the Sun, and understanding dense blooms like those now occurring on Lake Erie and other lakes worldwide.
