As many as a thousand genes may contribute to the risk for autism. That’s according to a new study by the Autism Sequencing Consortium published his week in the journal Nature. In the largest study of its kind, researchers examined DNA samples from more than 14,000 individuals, including several hundred Utah families. The result was that they dramatically expanded the list of genes identified with autism spectrum disorder.

Diet and exercise alone may not be enough to help people who are severely overweight. A new study by researchers at LDS Hospital and the University of Utah School of Medicine shows that patients who have gastric bypass surgery are much more likely to maintain weight loss and reduce their risk for serious disease than obese individuals who don’t have the surgery.
