Is binge eating a tell-tale sign of suicidal thoughts? According to a new study of African American girls, by Dr. Rashelle Musci and colleagues from the Bloomberg School of Public Health, Johns Hopkins University in the US, those who experience depressive and anxious symptoms are often dissatisfied with their bodies and more likely to display binge eating behaviors. These behaviors put them at higher risk for turning their emotions inward, in other words, displaying internalizing symptoms such as suicide. The study is published online in Springer's journal, Prevention Science.

Could turning on a gene prevent diabetes?

Posted: 22 Jul 2013 09:33 AM PDT

Type 2 diabetes accounts for 90 % of cases of diabetes around the world, afflicting 2.5 million Canadians and costing over 15 billion dollars a year in Canada. It is a severe health condition which makes body cells incapable of taking up and using sugar. Dr. Alexey Pshezhetsky of the Sainte-Justine University Hospital Research Center, affiliated with the University of Montreal, has discovered that the resistance to insulin seen in type 2 diabetics is caused partly by the lack of a protein that has not previously been associated with diabetes.
