Ecophysiological Study Of Green Microalgae Isolated From The Grit Crust Of The Atacama Desert
Terrestrial algae play a critical, yet often overlooked, role in the functioning of biological soil crusts (biocrusts), which are considered microecosystems, particularly in extreme environments.

Energy-Limited Radiolytic Habitability in the Shallow Martian Subsurface: Implications for ExoMars Rosalind Franklin and Tianwen-3
The surface of Mars is sterilized by ionizing radiation and pervasive oxidants; its shallow subsurface, shielded from ultraviolet light and the most reactive oxidation, may instead preserve habitable conditions.

Coordinated Proteome-scale Remodeling Underlies Polyextremophilic Survival In Antarctic Cryo-hypersaline Brines
Introduction – Cryo-hypersaline brines combine sub-zero temperatures with near-saturated salinity, creating one of Earth’s most extreme habitats. Antarctic Deep Lake provides a natural model for studying how proteins remain stable […]

Probing The Habitability Of Potential Sulfuric Acid Rich Subsurface Lakes In Europa’s Ice Shell Via Saci/STIV Integrated Models
Experimentally modeling the habitability of extreme ocean world conditions, such as those on Jupiter’s moon: Europa, would benefit from integrated microbe-virus model studies to provide both a microbial model and […]

Acidophilic Fungi As Possible Candidates For Living Forms In Venus’ Clouds
Present-day Venus, similar to Earth in terms of relative radius, acceleration of gravity and mean density, is characterised by a very strong greenhouse effect and full cloud cover.

Bipolar Investigation Of Near-surface Glacial Ice Reveals An Active Microbial Ecosystem Driven By Photosynthesis And Chemolithoautotrophy
Despite extreme conditions including freezing temperatures, low water activity, and few nutrients, active microorganisms are thought to inhabit glacial ice, yet little is known about their identities and methods of […]

The Genetic Determinants of Extreme UV Radiation and Desiccation Tolerance in a Bacterium Recovered from the Stratosphere
Microbes that survive transport to and in the stratosphere endure extremes of low temperature, atmospheric pressure, and relative humidity, as well as high fluxes in ultraviolet radiation (UVR).

The Deep Sea Is An Untapped Evolutionary Engine Says New Study
Editor’s note: As we expand outward from Earth to other worlds we are almost certainly going to encounter things we did not expect to find – things that are unlikely […]
