Seafloor Microbes Abundant and Thriving....An Alternative Cradle for Life?
Researchers from NAI’s Marine Biological Laboratory Team continue their study of the deep biosphere, reporting the latest results in this week’s Nature. This new study reveals that bacterial communities dwelling on ocean-bottom rocks are more abundant and diverse than previously thought, especially relative to the overlying water column. The microbes appear to “feed” on the oceanic crust through seawater–rock alteration reactions...

Astrobiology Researchers Earn Kudos
Four researchers whose work is supported by NASA’s Astrobiology Program were singled out for recognition by their scientific peers last year. Norman R. Pace, Mitchell L. Sogin, John P. Grotzinger, and Nora Noffke all received awards in 2007 for their contributions to science.
Norman Pace, professor of molecular, cellular, and developmental biology at the University of Colorado in Boulder, earned the American Society for Microbiology (ASM) 2007 Abbott-ASM Lifetime Achievement Award for outstanding contributions to...

Astrobiology on Science Friday
On today’s edition of NPR’s Science Friday, new work from NAI’s MBL team is featured, focusing on diversity of bacteria at hydrothermal vents. The team conducted a survey of DNA from deep-sea samples, discovering thousands of new kinds of marine microbes at two deep-sea hydrothermal vents off the Oregon coast.

Microbial Population Structures in the Deep Marine Biosphere
NAI’s Marine Biological Laboratory Team has a new paper in this week’s Science detailing aspects of population structure for microbial communities at two neighboring hydrothermal vents. Using environmental DNA sequencing techniques, they found the two populations reflect the geochemical conditions of each vent.

The Encyclopedia of Life
This week’s issue of Nature features an interview with David “Paddy” Paddington of NAI’s Marine Biological Laboratory Team discussing his involvement with the Encyclopedia of Life project. Debuting in early 2008, the EOL will be a living catalogue of biodiversity, with one webpage for each of Earth’s 1.8 million species.

A New Model for the Early Ocean
NAI’s Marine Biological Laboratory and Carnegie Institution of Washington Teams are contributing authors on a new paper in Earth and Planetary Science Letters presenting a new model for the evolution of Proterozoic deep seawater composition based on rare earth elements. Their data suggest transitional, suboxic conditions in the deep ocean (vs. sulfidic), which likely limited nutrient concentrations in seawater and, consequently, may have constrained biological evolution.

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.

A Window into the Subsurface Microbial Population
A new paper this week in PNAS highlights a collaboration between NAI Lead Teams at Penn State, University of Rhode Island, UCLA, and the Marine Biological Laboratory. Their research reveals that heterotrophic Archea dominate the scene in a variety of biogeochemically distinct sedimentary regions, and may constitute a significant portion of the prokaryotic biomass in Earth’s subsurface. Ecosystem-level carbon budgets suggest that community turnover times are on the order of 100-2,000 years.
