The bacterium Vibrio cholerae annually causes millions of cases of the often fatal disease cholera, typically in regions where access to clean drinking water is limited. V. cholerae can be introduced into water by infected individuals who can sometimes be asymptomatic, however this microbe is also a natural inhabitant of aquatic waters.
By studying rapidly evolving bacteria as they diversify and compete under varying environmental conditions, researchers have shown that temporal niches are important to maintaining biodiversity in natural systems. The research is believed to be the first experimental demonstration of temporal niche dynamics promoting biodiversity over evolutionary time scales.
Gross-chromosomal rearrangements are a hallmark of cancers and hereditary diseases. On the other hand, these events can trigger the generation of polymorphisms and lead to evolution. The driving force behind chromosomal rearrangements is DNA double strand breaks.
The new Engineered Biosystems Building will be a giant leap forward in creating the infrastructure that inspires and sustains scientific discovery at Georgia Tech. EBB will enable us to expand our commitment to improving and saving lives by providing bringing new treatments, medical technologies, medications, and therapies to patients.
Eric Gaucher, associate professor in Georgia Tech's School of Biology, was named as one of 14 young faculty from seven nations to receive an early career grant by DuPont. The DuPont Young Professor program is designed to help promising young and untenured research faculty begin their research careers.The $75,000 award is unrestricted and not tied to a specific research project.
A new study of both computer-created and natural proteins suggests that the number of unique pockets – sites where small molecule pharmaceutical compounds can bind to proteins – is surprisingly small, meaning drug side effects may be impossible to avoid. The study also found that the fundamental biochemical processes needed for life could have been enabled by the simple physics of protein folding.
Future teams of subterranean search and rescue robots may owe their success to the lowly fire ant, a much despised insect whose painful bites and extensive networks of underground tunnels are all-too-familiar to people living in the southern United States.
On April 24th, graduating seniors gathered with Biology faculty, researchers, and other students to present and celebrate their undergraduate research projects. Biology majors at Georgia Tech are required to complete a senior research experience in which they conduct an individual research project mentored by a faculty member or participate in a group research project undertaken as part of the Research Project Lab course.
A new study in fish shows how the strength and timing of competing molecular signals during brain development has generated natural and presumably adaptive differences in a brain region known as the telencephalon -- much earlier than scientists had previously believed.
A new study provides details of the structure and tissue properties of the unique adhesion system used by remora fish to attach themselves to sharks and other marine animals. The information could lead to a new engineered reversible adhesive that could be used to create pain- and residue-free bandages, attach sensors to objects in aquatic or military reconnaissance environments, replace surgical clamps and help robots climb.
