A team of scientists from several U.S. institutions, including the University of Minnesota, discovered six million year old ice in Antarctica — the oldest dated ice on the planet.
Protein diffusion, critical for cellular metabolism, occurs in the highly crowded cytoplasm. Understanding how this dynamics changes when organisms are adapted to different thermal niches is a fundamental challenge in […]
On planet Earth, the inner part of cave systems represents an extreme and isolated environment, characterized by relatively stable microclimatic conditions, nutrient limitation and protection from external stressors such as […]
From Europa to other icy moons, scientists are studying how surface features form and what they might reveal about the potential for life.

Keith’s note: Astrobiologist Dale Andersen will be back in Antarctica at Lake Untersee from early January through the end of February 2026 for another field season of research, leading an […]
Arthrobacter are commonly isolated from cold soil environments globally, including those that regularly reach sub-freezing temperatures, suggesting that Arthrobacter have significant potential for growth and activity under temperature and stress […]
An international team of scientists and students, led by the Arctic University of Norway, and including chemists and engineers from Woods Hole Oceanographic Institution (WHOI), has announced a remarkable discovery […]
Hydrothermal systems are widespread in our solar system. Identification of alteration mineral assemblages on Mars and potentially in ocean worlds such as Enceladus suggests the existence of extensive hydrothermal fluid-igneous […]
Arctic sea ice has declined by more than 42% since 1979, when regular satellite monitoring began. As the ice grows thinner and recedes, more water is exposed to sunlight.
