Metagenomics Untangles Potential Adaptations of Antarctic Endolithic Bacteria at the Fringe of Habitability
From 109 endolithic microbiomes, 4,539 metagenome-assembled genomes were generated, 49.3 % of which were novel candidate bacterial species.
Some Bacteria Could Survive Under Mars Conditions
An international team of radiation specialists, biologists and infectious disease experts has found four types of bacteria that are capable of surviving exposure to the hostile Mars environment. In their […]
New Tool Reveals Gene Behavior In Bacteria
Bacterial infections cause millions of deaths each year, with the global threat made worse by the increasing resistance of the microbes to antibiotic treatments.
Correlations Between Life-Detection Techniques and Implications for Sampling Site Selection in Planetary Analog Missions
We conducted an analog sampling expedition under simulated mission constraints to areas dominated by basaltic tephra of the Eldfell and Fimmvörðuháls lava fields (Iceland).
A Low-Diversity Microbiota Inhabits Extreme Terrestrial Basaltic Terrains and Their Fumaroles: Implications for the Exploration of Mars
A major objective in the exploration of Mars is to test the hypothesis that the planet hosted life. Even in the absence of life, the mapping of habitable and uninhabitable […]
A Spectrum Of Possibilities: Insights Into The Evolution Of Far-red Light Photosynthesis
A collaborative study led by Dr. Christopher Gisriel at Yale University and Dr. Tanai Cardona at Queen Mary University of London, published in Frontiers in Plant Science, offers new insight […]
Unlocking Long-term Genetic Memory: Dormant Bacterial Spores Offer Key Insights Into Evolutionary Survival Strategies
A recent study spearheaded by Prof. Sigal Ben Yehuda and her team at Hebrew University has unveiled a captivating facet of bacterial dormancy. This research illuminates the mechanism through which […]
Bacteria-virus Arms Race Provides Rare Window Into Rapid And Complex Evolution
As conceived by Charles Darwin in the 1800s, evolution is a slow, gradual process during which species adaptations are inherited incrementally over generations. However, today biologists can see how evolutionary […]
