Located between 200 and 1,000 meters below the ocean surface is a "twilight zone" where insufficient sunlight penetrates for microorganisms to perform photosynthesis. Details are now emerging about a microbial metabolic pathway that helps solve the mystery of how certain bacteria capture carbon in the dark ocean, enabling a better understanding of what happens to the carbon that is fixed in the oceans every year. They appear in the September 2, 2011, edition of Science.

 | Microorganisms play an important role in global nutrient cycles. A research team led by Christa Schleper, head of the Department of Genetics in Ecology at the University of Vienna, has isolated the first ammonium oxidizing Archaeon from a soil in Vienna and thus proved its activity. The researchers present their results on "Nitrososphaera viennensis" in the newest edition of the Proceedings of the National Academy of Sciences. ...> Full Article |
 | For nearly a decade, Jillian Banfield and her UC Berkeley colleagues have been studying the microbe community that lives in one of the most acidic environments on Earth: the drainage from a former copper mine in Northern California. One group of these microbes, dubbed ARMAN, seems to be smaller, and weirder, than any other known, free-living organism. Occasionally, it gets impaled by it larger neighbors. ...> Full Article |
