A compendium of bacterial and archaeal single-cell amplified genomes from oxygen deficient marine waters
A major challenge for earth scientists is to understand how oceans respond to decreasing oxygen levels. Areas of low oxygen, oxygen minimum zones (OMZs) and anoxic marine zones (AMZs), are predicted to increase in both expanse and frequency in response to climate warming and human modifications of coastal zones. Global warming is causing oxygen-deficient waters to expand and intensify. Therefore, studies focused on microbial communities inhabiting oxygen-deficient regions are necessary to both monitor and model the impacts of climate change on marine ecosystem functions and services. This study presents a compendium of 5,129 single-cell amplified genomes (SAGs) from marine environments encompassing representative OMZ and AMZ geochemical profiles. The study's researchers include Frank Stewart, associate professor in the Department of Microbiology and Immunology at Montana State University and an adjunct professor in the School of Biological Sciences.Nature Scientific Data May 27, 2023
A team of mechanical engineering students and alumni at Georgia Tech began developing and testing ForageFeeder, a $400 machine partly inspired by deer feeders that can disperse gorillas’ their meals at random intervals and locations throughout the day. Much like modern humans, zoo animals frequently deal with obesity due to a lack of activity. Tools and techniques such as the ForageFeeder not only promote Zoo Atlanta gorillas’ movement, but better simulate their natural foraging world. David Hu, professor in the School of Biological Sciences, the George W. Woodruff School of Mechanical Engineering, and the School of Physics, was faculty advisor for this project.

NPR's Ari Shapiro talks with Regina Barber and Emily Kwong, hosts of the Short Wave podcast, about the top science stories of the week, including the mysteries of multicellular organisms as researched by William Ratcliff, associate professor and co-director of the Interdisciplinary Ph.D. in Quantitative Biosciences program in the School of Biological Sciences. Ratcliff and several colleagues, including research scientist Ozan Bozdag, used snowflake yeast to initiate the first long-term evolution experiment aimed at evolving new kinds of multicellular organisms from single-celled ancestors in the lab. Other College of Sciences researchers involved include Seyed Alireza Zamani Dahaj, computational biologist, Interdisciplinary Graduate Program in Quantitative Biosciences, and the School of Physics; Thomas C. Day, Ph.D. candidate, School of Physics, and Peter Yunker, associate professor, School of Physics. Anthony J. Burnetti, research scientist; Penelope Kahn, research technician; Dung T. Lac, research technician; Kai Tong, postdoctoral scholar; and Peter Conlin, postdoctoral scholar, are all from the School of Biological Sciences.
