In ocean expanses where oxygen has vanished, newly discovered bacteria are diminishing additional life molecules. They help make virtual dead zones even deader. Now, a team led by the Georgia Institute of Technology has discovered members of a highly prolific bacteria group known as SAR11 living in the world’s largest oxygen minimum zone. The team has produced unambiguous evidence that the bacteria play a major role in denitrification.

Two School of Civil and Environmental Engineering Ph.D. students have secured National Science Foundation fellowships, some of the most competitive and prestigious funding for the nation’s graduate students. Georgene Geary and Laura Mast join a long list of the brightest and most promising of the School’s students to win the funding. This year, NSF chose to support fewer than one in eight applicants.

What’s that old saying about being in the right place at the right time? For Ph.D. student Aaron Bivins, news last week that he has won a Fulbright Scholarship means he’ll get to experience the reality of that maxim.

The human microbiome, a diverse collection of microorganisms living inside us and on our skin, has attracted considerable attention for its role in a broad range of human health issues. Now, researchers are discovering that the built environment also has a microbiome, which includes a community of potentially-pathogenic bacteria living inside water supply pipes. A paper published March 11 in the journal Applied and Environmental Microbiology describes microbial communities found in shower hoses at a major U.S. hospital. The study documented bacteria – and related genes – using cutting-edge metagenomic techniques that allow the characterization of organisms that cannot be detected using traditional culture-based microbiology assays.
