Geographic and Ecological Diversity of Green Sulfur Bacteria in Hot Spring Mat Communities

Three strains of thermophilic green sulfur bacteria (GSB) are known; all are from microbial mats in hot springs in Rotorua, New Zealand (NZ) and belong to the species Chlorobaculum tepidum.

Laboratory Characterization Of Hydrothermally Processed Oligopeptides In Ice Grains Emitted By Enceladus And Europa

The Cassini mission provided evidence for a global subsurface ocean and ongoing hydrothermal activity on Enceladus, based on results from Cassini’s mass spectrometers. Laboratory simulations of hydrothermal conditions on icy […]

Ocean Planet Mapping: On The Way To A Complete Seafloor Map For Our Homeworld

At least twice in the last 20 years, nuclear submarines have collided with previously unknown underwater mountains called seamounts. The reason: they were not on any nautical charts. Just last […]

A Surface Hydrothermal Source of Nitriles and Isonitriles

Giant impacts can generate transient hydrogen-rich atmospheres, reducing atmospheric carbon. The reduced carbon will form hazes that rain out onto the surface and can become incorporated into the crust. Once […]
