Icelandic Hot Springs as a Prebiotic Analog: Wet-Dry Cycling Effects on the Stability of Nucleotides and Nucleic Acids

by Keith Cowing

The hot spring hypothesis for the origin of life proposes that naturally occurring wet-dry cycles in small bodies of water could have driven condensation reactions on prebiotic Earth.

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

by Keith Cowing

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.
