Molecular Adaptations And Engineering Of Extremophiles For Synthetic Biology And Biotechnological Applications
Extremophiles are microorganisms that thrive in environments previously thought to be uninhabitable, including extreme temperature, salinity, pH, pressure, and radiation.
Limits of Terrestrial Life and the Probability of Growth on Mars: Call for Speakers and Topics
The National Academies’ Committee on Planetary Protection is hosting a virtual meeting that will inform NASA’s efforts to develop a prioritized list of factors that contribute to the potential release […]
Do Extreme Environments Shape Microbial Genomes?
Evolutionary biologists have long known that DNA, the molecule that carries the genetic instructions for the development, functioning, growth and reproduction of all organisms, contains a record of ancestry. Indeed, […]
Modularity, Ecology, And Theoretical Evolution Of The Ribozyme Body Plan
Ribozymes are relics of molecular life forms from the primitive earth that are embedded within modern genomes across all kingdoms of life. Despite significant knowledge from decades of bioinformatic and […]
Editorial: Life Under Pressure: Microbial Adaptation And Survival In High Pressure Environments
A quantitative overview of Earth’s biomass has long been lacking, despite its importance for understanding the biosphere. The first global estimate—approximately 550 gigatons of carbon (Gt C)—reveals stark disparities across […]
Recent Microbial Evolutionary Insights From Metagenomics
Microorganisms have profoundly shaped Earth’s biological and geological history, from the origins of oxygenic photosynthesis to present-day global biogeochemical cycles.
Growth Of Microorganisms In A Martian Regolith Simulant At Reduced Water Activity
Water activity (aw) quantifies the free water available for microbial growth. At the cellular level, liquid water is paramount for replication and proliferation. Research on Earth-like life suggests that microbial […]
Can Yeast Survive On Mars?
Baker’s yeast (Saccharomyces cerevisiae) is an indispensable ingredient in making bread, beer, and biotechnology products. But this humble organism also holds clues to something more cosmic – how life could […]
Erosion Of Iceberg A-23A Sparks A Surge Of Microscopic Life
Iceberg A-23A has had a more eventful run than most of the large Antarctic icebergs that have calved from the continent’s ice shelves in recent decades. Over its winding, forty-plus-year […]
