Much of the Earth's surface, both marine and terrestrial, is either periodically or permanently
cold. Although habitats that are largely or continuously frozen are generally considered to be …

BRCA1 is a large multi-domain protein with a pivotal role in maintaining genome stability
and cell cycle progression. Germline mutations in the BRCA1 gene confer an estimated …

Life can persist under severe osmotic stress and low water activity in hypersaline
environments. On Mars, evidence for the past presence of saline bodies of water is prevalent …

Microbial blooms colonize the Greenland Ice Sheet bare ice surface during the ablation
season and significantly reduce its albedo. On the ice surface, microbes are exposed to high …

In the atmosphere, airborne microbial cells are exposed to conditions that are thought to
affect their survival. Here, we investigated the survival of 5 microorganisms among the most …

Climate change is already altering the landscape at high latitudes. Permafrost is thawing,
the growing season is starting earlier, and, as a result, certain regions in the Arctic may be …

Arctic regions and their water bodies are affected by a rapidly warming climate. Arctic lakes
and small ponds are known to act as an important source of atmospheric methane …

Nature exhibits an enormous diversity of organisms that thrive in extreme environments.
From snow algae that reproduce at sub-zero temperatures to radiotrophic fungi that thrive in …

While most studies on allelopathic interactions among autotrophic microorganisms focus on
free-living aquatic species, little is known about microalgal biofilms, where chemical …

The glacier ice algae Ancylonema alaskanum and Ancylonema nordenskiöldii grow in harsh
dynamic environments on bare ice surfaces. In these environments, they contribute to the …
