Stem Cells Faulty in Duchenne Muscular Dystrophy

December 17, 2014 4:03 pm | by Stanford University | Comments

Like human patients, mice with a form of Duchenne muscular dystrophy undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers.

Targeted Computer Games Can Change Behavior of Psychopaths

December 17, 2014 11:03 am | by NYU Langone | Comments

Psychopaths generally do not feel fear and fail to consider the emotions of others, or reflect upon their behavior — traits that make them notoriously difficult to treat.

New Technology Advances Eye Tracking As Biomarker for Brain Function

December 17, 2014 10:59 am | by NYU Langone | Comments

Researchers at NYU Langone Medical Center have developed  new technology that can assess the location and impact of a brain injury merely by tracking the eye movements of patients as they watch music videos for less than four minutes, according to a study publishedin the Journal of Neurosurgery.

Amount of Mitochondrial DNA Predicts Frailty and Mortality

December 17, 2014 10:35 am | by Johns Hopkins | Comments

New research from The Johns Hopkins University suggests that the amount of mitochondrial DNA (mtDNA) found in peoples’ blood directly relates to how frail they are medically. This DNA may prove to be a useful predictor of overall risk of frailty and death from any cause 10 to 15 years before symptoms appear.

DNA Sheds Light on Why Largest Lemurs Disappeared

December 17, 2014 10:25 am | by Duke University | Comments

Ancient DNA extracted from the bones and teeth of giant lemurs that lived thousands of years ago in Madagascar may help explain why the giant lemurs went extinct. It also explains what factors make some surviving species more at risk today, says a study in the Journal of Human Evolution.

Interactions Between Proteins Govern Tumor Suppression, Aging

December 16, 2014 12:54 pm | by UC Davis | Comments

Scientists have long known the p53 protein suppresses tumors. However, a recent animal study by UC Davis researchers has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels. Too much Rbm38 reduces p53 levels, increasing the risk of cancer. Too little Rbm38 allows p53 overexpression, causing premature aging.
