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.
Each team to receive $100K for two years to kick-start new research.
A new study, published in Hepatology, from Chong Shin's lab shows the regenerative capacity of liver cells.
Congratulations to Dr. Greg Gibson for being awarded a T32 training grant from the National Institute of General Medical Science. Titled, "Computational Biology and Predictive Health”, the grant will bridge Biology, Biomedical Engineering, Industrial Systems Engineering and Computer Science through the support of 4 graduate students each year over the five funding period. The Executive Committee for the grant includes Greg Gibson, Melissa Kemp, King Jordan and Nicoleta Serban.
Study may dramatically shift our understanding of the complex dance of microbes and minerals that takes place in aquifers deep underground. This dance affects groundwater quality, the fate of contaminants in the ground and the emerging science of carbon sequestration.
Jeanette Yen, professor in the School of Biology, and a team of scientists spend the summer in Antarctica studying how plankton may be a canary in the coal mine of climate change.
