Variety Is the Splice of Life
Mark Young from NAI’s Montana State University Team and Jill Banfield from NAI’s Emeritus Team at UC Berkeley have teamed up to study genetic exchange in bacterial and archeal populations. Their new Science paper, Variety—the Splice of Life—in Microbial Populations, describes the effects of their exchange of genetic material – from useless to critical in terms of selection. They also observed the splicing of viral material.

Found: A Hyperthermophilic Nitrogen Fixer
Researchers from NAI’s Carnegie Institution of Washington Team have published in Science their findings of a novel archaeon who’s ability to fix nitrogen at 92 degrees Celcius has officially increased the upper limit of biological nitrogen fixation by 28 degrees Celcius. The hyperthermophilic methanogen was isolated from a hydrothermal vent. Thier findings could reveal a broader range of conditions for life in the subseafloor biosphere.
