Molecular docking unlocks function of enzymes

Fitting a key into a lock may seem like a simple task, but researchers at Texas A&M University are using a method that involves testing thousands of keys to unlock the functions of enzymes, and their findings could open the door for new targets for drug designs.

Study looks at link between weight and causes of death

The association between weight and causes of death can vary considerably, with obesity associated with a significantly increased mortality from cardiovascular disease (CVD), underweight associated with increased mortality from primarily non-cancer, non-CVD causes, and overweight associated with increased mortality from diabetes and kidney disease combined, but with reduced mortality from other non-cancer non-CVD causes of death, according to a study in the November 7 issue of JAMA.
