Making Sense of Mars Methane
Research on methane at a Mexican salt flat could help reveal the source of methane that has been detected in the atmosphere of Mars. But first scientists have to decipher the unique – and seemingly contradictory – isotopic signature of the Mexican methane.

Biodiversity in Hypersaline Mats
Researchers at NAI’s University of Colorado, Boulder and Marine Biological Laboratory Team published their analysis of biodiversity in hypersaline microbial mats in a recent issue of Applied and Environmental Microbiology. Bacteria dominated the mat in unprecedented diversity representing 752 species, including 15 novel candidate phyla.
