Unusual comparison nets new sleep loss marker

Posted: 03 May 2013 10:40 AM PDT

For years, Paul Shaw, PhD, a researcher at Washington University School of Medicine in St. Louis, has used what he learns in fruit flies to look for markers of sleep loss in humans.

Shaw reverses the process in a new paper, taking what he finds in humans back to the flies and gaining new insight into humans as a result: identification of a human gene that is more active after sleep deprivation.

Injectable Nano-Network Controls Blood Sugar in Diabetics for Days at a Time

Posted: 03 May 2013 08:21 AM PDT

In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests. The work was done by researchers at North Carolina State University, the University of North Carolina at Chapel Hill, the Massachusetts Institute of Technology and Children’s Hospital Boston.
