A molecular switch syncs fat-burning to the body clock, our diet and the temperature around us

A protein in the brown fat of mice sits at the intersection of three metabolic controls: the body's 24-hour clock, the temperature outside, and our diet. The discovery helps explain how the body can keep a daily rhythm of energy metabolism, and still respond the moment its energy needs change. The discovery by scientists at the University of Copenhagen and their international collaborators was published in Science.
