Dr. Marc Weissburg Professor of Biology, along with a team of multidisciplinary investigators have been awarded $2.5 million dollar grant to develop approaches for sustainable and resilient infrastructure. A key feature of the plan is to use, and compare, ecological and engineering approaches and principles for increasing cycling, reducing waste, and maintaining function in the face of perturbation. The team will examine complex interactions between infrastructure (e.g. water, transportation and energy systems) that traditionally have been ignored.
The ability to accurately repair DNA damaged by spontaneous errors, oxidation or mutagens is crucial to the survival of cells. This repair is normally accomplished by using an identical or homologous intact sequence of DNA, but scientists have now shown that RNA produced within cells of a common budding yeast can serve as a template for repairing the most devastating DNA damage – a break in both strands of a DNA helix.
GT Biology 2012 PhD graduate Douglas Rasher won the George Mercer Award from the Ecological Society of America this year. This prestigious award recognizes the best paper published in Ecology over the past 2 years by an ecologist younger than 40 years old
Following the oil spill caused by the blowout at the Macondo wellhead in 2010, Gulf of Mexico microbial population dynamics shifted rapidly as numbers of oil degraders quickly increased. In addition, the spill provided an opportunity to study the newly described phenomenon of microbe-derived marine snow.
Dr. Joel Kostka, a Professor jointly appointed in Biology and Earth & Atmospheric Sciences, was recently awarded $1.0 million in research grants by the U.S. Department of Energy (DOE) to study the microbially-mediated carbon cycle in boreal or northern peatlands. Peatlands sequester one-third of all soil carbon and currently act as major sinks of atmospheric CO2.
