Preventing Diabetes

In this photo taken Wednesday, May 13, 2015, Hayden Murphy, 13, sits for a photo with his medicine at his home in Plainfield, Ill. Hayden is among more than 400 children and adults participating in U.S. government-funded international research investigating whether experimental insulin capsules can prevent or at least delay Type 1 diabetes. To enroll, participants must first get bad news: results of a blood test showing their chances for developing the disease are high. (AP Photo/Nam Y. Huh)
