Modeling pN2 through Geological Time: Implications for Planetary Climates and Atmospheric Biosignatures [PDF]
Nitrogen is a major nutrient for all life on Earth and could plausibly play a similar role in extraterrestrial biospheres. The major reservoir of nitrogen at Earth's surface is atmospheric N2, but recent studies have proposed that the size of this ...

Metagenomic insights into S(0) precipitation in a terrestrial subsurface lithoautotrophic ecosystem
The Frasassi and Acquasanta Terme cave systems in Italy host isolated lithoautotrophic ecosystems characterized by sulfur-oxidizing biofilms with up to 50% S(0) by mass.

Red-edge position of habitable exoplanets around M-dwarfs
One of the possible signs of life on distant habitable exoplanets is the red-edge, which is a rise in the reflectivity of planets between visible and near-infrared (NIR) wavelengths.

Adaptationism fails to resolve Fermi's paradox [PDF]
One of the most interesting problems in the nascent discipline of astrobiology is more than half-century old Fermi's paradox: why, considering extraordinary young age of Earth and the Solar System in the Galactic context, don't we perceive much older ...

The archaeal class Halobacteria and astrobiology: Knowledge gaps and research opportunities
Water bodies on Mars and the icy moons of the outer solar system are now recognized as likely being associated with high levels of salt. Therefore, the study of high salinity environments and their inhabitants has become increasingly relevant for ...

A sustainable culture of tardigrades (Hypsibius dujardini) for astrobiological laboratory activities [PDF]
Tardigrades are microscopic organisms that have gained importance in astrobiology in recent years. They have extreme survival ability and can enter into a state of latency for several years called cryptobiosis.
