Since his arrival on campus in 2004, molecular biologist and Tech Professor John McDonald has been hard at work developing new solutions and strategies for targeting and treating cancer. Some of his latest research concerns the use of nanoparticles to seek out and deliver treatments to ovarian cancer cells without damaging the body’s healthy cells. Designing this technology has required collaboration between the McDonald Lab in the School of Biology and Andrew Lyon’s lab in the School of Chemistry.
The sheer volume of cyanobacteria in the oceans makes them major players in the global carbon cycle and responsible for as much as a third of the carbon fixed. These photosynthetic microbes, which include Prochlorococcus and Synechococcus, are tiny – as many as 100 million cells can be found in a single liter of water – and yet they are not the most abundant entities on Earth. That distinction goes to viruses, up to 100 million of which can be found per 1 mL of seawater. However, researchers know very little about the viruses in the water, other than that there are three kinds of viruses, and that they are capable of drastically decreasing cyanobacterial populations, affecting the global regulation of biogeochemical cycles.
Georgia Tech scientists aren’t content with just making discoveries, they want to contribute to the community as well. That’s why this summer, Tonya Shearer, research scientist in the School of Biology, opened the Discover Science Center (DSC), a science enrichment lab serving the metro-Atlanta area.
Researchers from Georgia Tech, Carnegie Mellon, Oregon State University, and Zoo Atlanta report that sidewinders improve their ability to traverse sandy slopes by simply increasing the amount of their body area in contact with the granular surfaces they’re climbing. They've put that knowledge to work helping a snake-like robot.
Highlighting unexpected similarities between what animals do and what people are trying to do is a new strategy Georgia Institute of Technology researchers are using to hopefully increase public awareness about animals and encourage conservation. They’ve created an iPhone app based on biologically inspired design, highlighting two dozen species that have helped engineers solve problems or invent new solutions.
Researchers have developed an automated imaging technique for measuring and analyzing the root systems of mature plants. The work could help plant scientists improve food crops to help meet the needs of a growing world population.
A group of researchers including Chong Shin, an assistant professor in the School of Biology and Christoph Fahrni, a professor in the School of Chemistry and Biochemistry at Georgia Tech conducted a study to visualize the distribution of transition metals in the zebrafish embryo by employing synchrotron X-ray fluorescence (SXRF) microtomography.
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.
