Novel Proteobacteria in Microbial Mats at Loihi Seamount
With support from NAI Teams at the Carnegie Institution of Washington and UC Berkeley, researchers at the American Type Culture Collection and their colleagues have a new paper in PLOS One describing a novel lineage of proteobacteria which are dominant in iron-rich hydrothermal vent sites on the Loihi Seamount near Hawai’i. They form a unique morphological structure which could serve as a fossil biomarker.

Extracellular Protein-Metal Aggregates: A New Biosignature?
Deep inside a flooded mine in Wisconsin, scientists from NAI’s University of California, Berkeley Team have discovered an environment in which bacteria emit proteins that sweep up metal nanoparticles into immobile clumps. Their finding may lead to innovative ways to remediate subsurface metal toxins, and have exciting implications for identifying biosignatures on Earth and other worlds. The research, published in the June 14th issue of Science, was done in collaboration with a team from the U.S. Department of Energy’s Lawrence...

Evidence for Ancient Ocean on Mars
Scientists from NAI’s University of California, Berkeley Team have a new paper out in Nature outlining evidence for the presence of an ancient ocean on Mars. The study points to a large body of liquid water at the pole which could have shifted Mars’ spin axis. This shift would have in turn deformed the shoreline of this ocean relative to the rest of the surface topography, in accordance with observations.

Low Abundance Acidophilic Archea Revealed
Scientists from NAI’s University of California, Berkeley Team report in this week’s Science on their use of shotgun sequencing to uncover three novel archea present in all biofilms growing in pH 0.5 to 1.5 solutions within the Richmond Mine, California. Their results inform the problem of characterizing microbial communities and lineages which are difficult to cultivate.

Life in the Landscape?
A review article in Nature this week from scientists on NAI’s University of California, Berkeley Lead Team examines the idea of the influence of life on topography. The authors call for a need to explore how small scale biotic processes can influence an entire landscape, and whether the resulting topography is distinct.
