Georgia Tech researchers used experiments and numerical calculations to show that iron, in the absence of oxygen, can substitute for magnesium in RNA binding, folding and catalysis. The findings suggest that 3 billion years ago, on the early earth, iron did the chemical work now done by magnesium.
A marine ecologist known for his work on community ecology and chemical ecology has been selected to receive the 2012 Robert L. and Bettie P. Cody Award in Ocean Sciences from Scripps Institution of Oceanography at UC San Diego.
New research findings show that embryonic stem cells unable to fully compact the DNA inside them cannot complete their primary task: differentiation into specific cell types that give rise to the various types of tissues and structures in the body.
Dr. Michael Cortez, a postdoctoral researcher in Dr. Joshua Weitz's Lab in the School of Biology, has received a Mathematical Sciences Postdoctoral Research Fellowship (MSPRF) from the National Science Foundation (NSF). This fellowship is an award of $150,000 over two years that supports Dr. Cortez's research in the fields of mathematics and theoretical biology.
Rachel Penczykowski, a Biology PhD student in Meghan Duffy’s lab, has been chosen as a winner of a PEO Scholar Award. This $15,000 award is given by the International Chapter of the PEO Sisterhood, which is a philanthropic group that promotes educational opportunities for women. The PEO Scholar Awards were established in 1991, and provide substantial merit-based support for women pursuing doctoral degrees.
When battling an epidemic of a deadly parasite, less resistance can sometimes be better than more. A new study suggests that a lake’s ecological characteristics influence how freshwater zooplankton Daphnia dentifera evolve to survive epidemics of a virulent yeast parasite Metschnikowia bicuspidate. The study found that Daphnia populations evolved either enhanced resistance or susceptibility to infection depending on the nutrient concentration and predation levels in the lake.
The Georgia Tech School of Biology is pleased to announce that three of our faculty won campus-wide teaching awards this year.
Two PhD students of the School of Biology, Mustafa Burak Boz and Jin Xu, received $1,500 travel grants for their posters at the recent Georgia Tech Research and Innovation Conference (GTRIC 2012).
Chong Shin (Assistant professor, School of Biology) has received a pilot grant from the Georgia Tech & Emory Center for Regenerative Medicine (GTEC).
Dr. Frank Stewart, an assistant professor in the School of Biology, has received a Faculty Early Career Development (CAREER) Award from the National Science Foundation (NSF). This award provides $1.2 million over five years in support of research and educational activities in Dr. Stewart’s field of marine microbiology. According to NSF, the CAREER Program “offers the National Science Foundation's most prestigious awards in support of junior faculty who exemplify the role of teacher-scholars through outstanding research, excellent education and the integration of education and research within the context of the mission of their organizations.”
