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.

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.

Going Deep
Some of the most arresting images of life on our planet have come from the deep-sea world of hydrothermal vents. Massive chimneys belching superheated fluids, colonies of giant crimson-tipped tubeworms swaying in the current, swarms of tiny shrimp, albino crabs. These ecosystems, although isolated from life on the surface, contain a virtual zoo of creatures, thriving under conditions of heat and pressure so extreme that, until the vent communities were discovered in the late 1970s, scientists did not even imagine...

Pyruving the Origin of Life
For the origin of life, chemical synthesis of pyruvic acid is a critical step. In a difficult experiment, Carnegie Institute/NAI researchers report that the natural synthesis of such compounds would occur wherever hot ocean vents pass through iron sulfide-containing crust.
