In a new study this week in Nature Medicine, Georgios Paschos PhD, a research associate in the lab of Garret FitzGerald, MD, FRS director of the Institute for Translational Medicine and Therapeutics, Perelman School of Medicine, University of Pennsylvania, shows that deletion of the clock gene Arntl, also known as Bmal1, in fat cells, causes mice to become obese, with a shift in the timing of when this nocturnal species normally eats. These findings shed light on the complex causes of obesity in humans. http://medicalxpress.com/news/2012-11-it-not-just-what-you.html Medical research Sun, 11 Nov 2012 13:05:41 EST news271861513 When Thomas Edison tested the first light bulb in 1879, he could never have imagined that his invention could one day contribute to a global obesity epidemic. Electric light allows us to work, rest and play at all hours of the day, and a paper published this week in Bioessays suggests that this might have serious consequences for our health and for our waistlines. http://medicalxpress.com/news/2012-08-clock-loss-daily-rhythms-obesity.html Medical research Wed, 29 Aug 2012 19:00:05 EST news265479681
