Researchers studying the impact of the Deepwater Horizon oil spill on communities of beach microbes saw a succession of organisms and identified population changes in specific organisms that marked the progress of the oil's breakdown.
The Georgia Institute of Technology hosted a two-day workshop, "Modeling the Spread and Control of Ebola in West Africa," with more than 180 participants to discuss the use of dynamical models to support, interpret and enhance public health practices to help stop the spread of the disease.
Researchers have developed and tested a new technique known as ribose-seq that allows them to determine the full profile of ribonucleotides -- RNA fragments -- embedded in genomic DNA.
For swimming through sand, a slick and slender snake can perform better than a short and stubby lizard. That’s one conclusion from a study of the movement patterns of the shovel-nosed snake, a native of the Mojave Desert of the southwest United States.
A new project will provide computational tools designed to help identify and characterize the gene diversity of the residents of microbial communities. The project, being done by researchers at the Georgia Institute of Technology and Michigan State University, will allow clinicians and scientists to compare the genomic information of organisms they encounter against the growing volumes of data provided by the world’s scientific community.
Dr. Joshua Weitz, Associate Professor of Biology, was named a Simons Foundation Investigator in Ocean Processes and Ecology and awarded a three-year grant from the Simons Foundation. Dr. Weitz will examine physical and ecological principles governing the interplay between viruses and zooplankton in the North Pacific Ocean.
In the latest issue of the journal Science, Will Ratcliff, assistant professor in Georgia Tech Biology, has a piece on a new theory he and Eric Libby, from the Santa Fe Institute, are positing that explains the rules governing how life may have evolved from single-celled organisms into multi-cellular productions.
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.
