Scientists Redraw the Blueprint of the Body's Biological Clock

The discovery of a major gear in the biological clock that tells the body when to sleep and metabolize food may lead to new drugs to treat sleep problems and metabolic disorders, including diabetes.

"This fundamentally changes our knowledge about the workings of the circadian clock and how it orchestrates our sleep-wake cycles, when we eat and even the times our bodies metabolize nutrients," says Evans. "Nuclear receptors can be targeted with drugs, which suggests we might be able to target REV-ERBα and β to treat disorders of sleep and metabolism."

Nurses, emergency personnel and others who work shifts that alter the normal 24-hour cycle of waking and sleeping are at much higher risk for a number of diseases, including metabolic disorders such as diabetes.
