The Lipidome of a Mars Analog Poly-Extreme Community in Atacama Halite Endolith: Chemotaxonomy, Lipid Adaptation, and Implications for the Search for Extraplanetary Biosignatures

by Keith Cowing

We analyzed the lipidome of the endolithic community in halite nodules from Salar Grande in the hyperarid Atacama Desert, which is considered an analog for martian subsurface environments.

The Limit of Life at Extremely Low Water Activity: Lithium-concentration Ponds in a Solar Saltern (Salar de Atacama, Chile)

by Keith Cowing

Extremely hyper-saline ponds from an industrial lithium-concentration process in solar salterns in the Atacama Desert were studied to determine the limits of life at very low water activity.
