Researchers explore changes in brain regions to combat sleep apnea

According to the National Heart, Lung and Blood Institute, the average sleep apnea sufferer stops breathing and loses oxygen between five and 30 times a night. This lack of oxygen leads to a host of complications, including high blood pressure, vascular disease, an abnormal heart rhythm, or even a fatal cardiac event. Now, a team of University of Missouri researchers is exploring the changes in distinct brain regions that contribute to these symptoms in hopes of combating this common health issue.

Mechanisms of body fat growth discovered

Using ice cream, candy bars and energy drinks to help volunteers gain weight, Mayo Clinic researchers have discovered the mechanisms of how body fat grows. Increased abdominal fat seems to heighten risk for metabolic disease, while fat expansion in the lower body -- as in the thighs -- seems to lower the risk. The findings, appearing in today's Proceedings of the National Academy of Sciences (PNAS), help explain why.

Research finds link between calcium and cancer

A protein that pumps calcium out of cells also moonlights as a signal to get massive quantities of the stuff to flow in, according to Johns Hopkins scientists. Their discovery of this surprisingly opposite function, reported Oct. 1 in Cell, highlights the link between calcium and cancer and holds the promise of a new therapeutic target for certain breast cancers.
