Researchers at Luca Technologies have made a discovery regarding natural gas production in Wyoming's Powder River Basin that could lead to a renewable source of energy for generations to come. The company today announced that laboratory evidence shows that the Powder River Basin (PRB) coals are generating natural gas in real time through the ongoing activity of anaerobic microbes (bacteria that live in the absence of oxygen) resident in those coal fields. The company has termed sites where this microbial conversion of hydrocarbon deposits (coals, organic shales, or oil) to methane occurs "Geobioreactors," and believes the careful management of such...

They thrive without oxygen, growing in salty, alkaline conditions, and may offer insights into what kinds of life might survive on Mars. They're a new species of organism, isolated by scientists at the National Space Science and Technology Center (NSSTC) in Huntsville, Ala. The discovery, published in the May 2003 issue of the International Journal of Systematic and Evolutionary Microbiology, identifies a species named Spirochaeta americana by the two NSSTC scientists -- Richard Hoover and Dr. Elena Pikuta. They isolated this new organism from oxygen-deprived mud sediments from Northern California's Mono Lake - a salty, alkaline lake in an enclosed...
