August 22, 2014 - Damaged coral reefs emit chemical cues that repulse young coral and fish, discouraging them from settling in the degraded habitat, according to new research. The study shows for the first time that coral larvae can smell the difference between healthy and damaged reefs when they decide where to settle.
August 20, 2014 - An analysis of patented university inventions licensed to biotechnology firms has revealed early bottlenecks on the path to commercialization. To open these roadblocks, the researchers suggest that better communication of basic research results during the discovery stage could lead to faster commercialization down the road.
July 21, 2014 - A recently improved telemedicine system was optimized by scientists at the Georgia Tech Research Institute (GTRI) and Cisco Systems, Inc. The system at Marcus Autism Center’s telemedicine room is now a showcase for providers of telemedicine, where improved video capabilities and an ergonomic suite allow patients in rural Georgia to meet face-to-face with medical specialists in Atlanta.
June 30, 2014 - The evolution of the ribosome, a large molecular structure found in the cells of all species, has been revealed in unprecedented detail in a new study.
June 25, 2014 - Stanley Miller, the chemist whose landmark experiment published in 1953 showed how some of the molecules of life could have formed on a young Earth, left behind boxes of experimental samples that he never analyzed. The first-ever analysis of some of Miller’s old samples has revealed another way that important molecules could have formed on early Earth.
May 29, 2014 -- A study of 338 patients with coronary artery disease has identified a gene expression profile associated with an elevated risk of cardiovascular death. Used with other indicators such as biochemical markers and family history, the profile – based on a simple blood test – may help identify patients who could benefit from personalized treatment and counseling designed to address risk factors.
May 29, 2014 - A new technology under development at the Georgia Institute of Technology could one day provide more efficient delivery of the bone regenerating growth factors with greater accuracy and at a lower cost.
May 8, 2014 - When ovarian cancer spreads from the ovaries it almost always does so to a layer of fatty tissue that lines the gut. A new study has found that ovarian cancer cells are more aggressive on these soft tissues due to the mechanical properties of this environment. The finding is contrary to what is seen with other malignant cancer cells that seem to prefer stiffer tissues.
May 5, 2014 -- According to a study published in the journal Proceedings of the National Academy of Sciences, co-evolutionary changes in species may reverse traditional predator-prey population cycles, creating the appearance that prey are eating the predators.
April 10, 2014 -- Researchers have developed a new understanding of the T-cell recognition process by describing how T-cell receptors use mechanical contact – the forces involved in their binding to antigens – to make decisions about whether or not the cells they encounter are threats.
