Researchers are improving the odds for people medically at risk from dehydration or congestive heart failure. They are improving and miniaturizing a medical device that monitors a person's hydration, or level of fluid. This is important to members of the military and to thousands of home health care patients, athletes, firefighters and first responders.

Researchers report new insights into how genetic variation may create phenotypic differences between individuals. This study, which investigates the influence of mutations associated with obesity on the mechanism of splicing, is published in Genome Research.

Scientists have found a new way to sort stem cells that should be quicker, easier and more cost-effective than current methods. The technique could in the future expedite therapies for people with conditions ranging from brain and spinal cord damage to Alzheimer's and Parkinson's diseases.

New data have indicated that the antimalarial drug chloroquine effectively prevents cancer in mouse models of two distinct human cancer syndromes, Burkitt lymphoma and ataxia telangiectasia.

Not all individuals who have epilepsy respond to traditional treatments. Strict adherence to a ketogenic diet high in fats and extremely low in carbohydrates is sometimes used to treat these patients. A new study shows that intranasal delivery of leptin, a hormone important in feeding and energy metabolism, delays the onset of convulsions in rodents, leading to the suggestion that leptin-triggered signaling may be a key to how a ketogenic diet combats epilepsy.
