Researchers in the School of Biology at Georgia Tech have uncovered a novel mechanism of genome mutagenesis and remodeling that could help to explain abnormal DNA amplification in cancer and other degenerative disorders. Cancer and other degenerative disorders are commonly associated with abnormal DNA amplification (resulting in an increase in the number of copies of a DNA segment) in various locations throughout the genome.

If the 4.9 million barrels of oil that spilled into the Gulf of Mexico during the 2010 Deep Water Horizon spill was a ecological disaster, the two million gallons of dispersant used to clean it up apparently made it even worse – 52-times more toxic. That’s according to new research from the Georgia Institute of Technology and Universidad Autonoma de Aguascalientes (UAA), Mexico.

New research from Georgia Aquarium and Georgia Institute of Technology provides evidence that a suite of techniques called “metabolomics” can be used to determine the health status of whale sharks (Rhincodon typus), the world’s largest fish species. The study, led by Dr. Alistair Dove, director of Research & Conservation at Georgia Aquarium and an adjunct professor at Georgia Tech, found that the major difference between healthy and unhealthy sharks was the concentration of homarine in their in serum—indicating that homarine is a useful biomarker of health status for the species.

Corals under attack by toxic seaweed do what anyone might do when threatened – they call for help. A study reported this week in the journal Science shows that threatened corals send signals to fish “bodyguards” that quickly respond to trim back the noxious alga.

Yingying Zeng, a graduate student in the School of Biology, is the lead author on a new paper that describes the complete structure of satellite tobacco mosaic virus (STMV). This is the first model for the structure of any virus that specifies the position of every single atom. Zeng combined high-resolution data from x-ray crystallography, chemical data on the structure of the RNA genome, and knowledge-based molecular modeling methods to develop her model.

Most of us gaze in wonder at how clouds of all different shapes and sizes form and vaporize across the beautiful October Atlanta sky. Few of us think about bacteria playing a role in this process. This is not the case for Natasha DeLeon-Rodriguez, a School of Biology graduate student in the lab of Kostas Konstantinidis (http://enve-omics.gatech.edu/).

Earlier this month a team of undergraduates brought home a silver medal in the 2012 International Genetically Engineered Machine (iGEM) competition. iGEM is considered the premiere undergraduate synthetic biology competition where teams design, construct and analyze novel biological systems to perform new functions in living cells.

New Georgia Tech research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they’re able to spread. The findings, which are published in the journal PLoS One, found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.

Dr. Joshua Weitz (Associate Professor, School of Biology) has been awarded a grant from the Program in Biological Oceanography on "Understanding the Effects of Complex Phage-Bacteria Infection Networks on Ocean Ecosystems". The award provides over $470,000 over 4 years to study the interaction between viruses and bacteria in ocean ecosystems.
