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 […]
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 […]
NASA’s Cassini spacecraft captured dramatic plumes, both large and small, spray water ice out from many locations along the famed ‘tiger stripes’ near the south pole of Saturn’s moon Enceladus.
Saturnian moon Titan presents a compelling testbed for probing prebiotic chemistry beyond early Earth. Impact-generated melt pools provide transient aqueous habitats in an otherwise cryogenic environment.
Despite growing evidence for the role of DNA methylation in bacterial acclimation to environmental stress, this epigenetic mechanism remains unexplored in sea-ice microbial communities known to tolerate multiple stressors.
A team of U.S. scientists has discovered the oldest directly dated ice and air on the planet in the Allan Hills region of East Antarctica.
The 2025 – 2026 Antarctic season is a landmark for the British Antarctic Survey (BAS) and its Antarctic Infrastructure Modernisation Project (AIMP), as the new Discovery Building begins to take […]
Frozen in time, ancient microbes or their remains could be found in Martian ice deposits during future missions to the Red Planet.
Researchers at Chalmers University of Technology in Sweden and the US space agency NASA have made an unexpected discovery that challenges one of the basic rules of chemistry and provides […]
