Dr. Cara Gormally, a teaching faculty member in the School of Biology, along with research collaborators Peggy Brickman and Mary Lutz at the University of Georgia, have developed the Test of Scientific Literacy Skills (TOSLS)--a freely available, psychometrically sound, multiple-choice instrument to measure college students’ scientific literacy skill development.
Researchers recently created a biophysical model of the response of a Gram-positive bacterium to the formation of a hole in its cell wall, then used experimental measurements to validate the theory, which predicted that a hole in the bacteria cell wall larger than 15 to 24 nanometers in diameter would cause the cell to lyse, or burst.
When you walk into Brian Hammer’s classroom, you might be greeted by the sounds of hip-hop artist Nicki Minaj or the Godfather of Soul James Brown. It all depends on the day’s lecture.
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.
The research team will use the comprehensive research approach of systems biology to study and catalog in molecular detail how malaria parasites interact with their human and animal hosts.
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/).
