October 5, 2012 — New Georgia Tech research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they’re able to spread. The findings, which are published in the journal PLoS One, found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.
October 2, 2012 — Modulating immune response to injury could accelerate the regeneration of severed peripheral nerves, a new study in an animal model has found. By altering activity of the macrophage cells that respond to injuries, researchers dramatically increased the rate at which nerve processes regrew.
October 1, 2012 — A new study from Georgia Tech and the University of Toronto suggests that memory impairments for people diagnosed with early stage Alzheimer’s disease may be due, in part, to problems in determining the differences between similar objects. The findings also support growing research indicating that a part of the brain once believed to support memory exclusively – the medial temporal lobe - also plays a role in object perception.
September 18, 2012 — Soon, parents may be able to skip the doctor’s visit and receive a diagnosis without leaving home by using Remotoscope, a clip-on attachment and software app that turns an iPhone into an otoscope.
September 9, 2012 — A study of more than 6,000 genes in a common species of yeast has identified the pathways that govern the instability of GAA/TTC repeats. In humans, the expansions of these repeats is known to inactivate a gene – FXN – which leads to Friedreich’s ataxia, a neurodegenerative disease that is currently incurable. In yeast, long repeats also destabilize the genome, manifested by the breakage of chromosomes.
August 23, 2012 — In research published in September’s American Journal of Human Genetics, Soojin Yi looked at brain samples of each species. She found that differences in certain DNA modifications, called methylation, may contribute to phenotypic changes. The results also hint that DNA methylation plays an important role for some disease-related phenotypes in humans, including cancer and autism.
August 22, 2012 — C. Ross Ethier, Ph.D., an internationally recognized leader in the area of biomechanics and mechanobiology recently joined the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University as the new Georgia Research Alliance Lawrence L. Gellerstedt, Jr. Eminent Scholar in Bioengineering.

August 13, 2012 — Researchers for the first time have shown that members of a family of enzymes known as cathepsins – which are implicated in many disease processes – may attack one another instead of the proteins they normally degrade. Dubbed “cathepsin cannibalism,” the phenomenon may help explain problems with drugs that have been developed to inhibit the effects of these powerful proteases.
August 7, 2012 — Professor John McDonald is studying micro RNAs (miRNAs), a class of small RNAs that interact with messenger RNAs (mRNAs) that have been linked to a number of diseases, including cancer. McDonald’s lab placed two different miRNAs (MiR-7 and MiR-128) into ovarian cancer cells and watched how they affected the gene system.
July 23, 2012 — Thanks to tiny microneedles, eye doctors may soon have a better way to treat diseases such as macular degeneration that affect tissues in the back of the eye. That could be important as the population ages and develops more eye-related illnesses – and as pharmaceutical companies develop new drugs that otherwise could only be administered by injecting into the eye with a hypodermic needle.
