Astrobiologists have outlined how geochemistry and metabolism are connected in the microbial ecosystem of the deep subsurface beneath Spain’s Rio Tinto region.
Habitability: Friction in Orbit
Jul 15, 2014
Friction could be the key to habitability on planets in treacherous, elliptical orbits.
Quantum Algae: Photosynthesis in Low Light
Jul 11, 2014
A new study in quantum biology has revealed a ‘weird’ phenomenon that algae use to survive in low light.
Astrobiologists Set UV Radiation Record
Jul 9, 2014
Astrobiologists from the United States and Germany have recorded the highest level of UV radiation yet known at the Earth’s surface.
