The brain-belly connection: Scientists find key genetic triggers in weight-regulating brain cells

The little voice inside your head that tells you to eat, or stop eating, isn’t a little voice — it’s actually a cluster of about 10,000 specialized brain cells. And now, an international team of scientists has found tiny triggers inside those cells that give rise to this “voice,” and keep it speaking throughout life. […]

Genetic code for diabetes in Greenland broken by scientists

A spectacular piece of detective work has mapped a special gene variant among Greenlanders which plays a particularly important role in the development of type 2 diabetes. The results have been published in Nature and can be used to improve prevention and treatment options for those genetically at-risk. In collaboration with Greenland researchers from Steno […]

Saturated fat intake may influence a person’s expression of genetic obesity risk

Limiting saturated fat could help people whose genetic make-up increases their chance of being obese. In a new study, researchers from the Jean Mayer USDA Human Nutrition Research Center on Aging (USDA HNRCA) at Tufts University identified 63 gene variants related to obesity and used them to calculate a genetic risk score for obesity for […]

Vitamin D hypothesis challenged: Some racial disparities in childbirth more environmental than genetic

A new study investigating racial disparities in birth outcomes shows that contrary to some theories Vitamin D is unlikely to play a role in differences in preterm birth and low birth weight between African-Americans and whites. “For years there has been this hypothesis that African-Americans have worse birth outcomes because they have more melanin in […]
