Scientists鈥� discovery of a molecular 鈥渟witch鈥� that activates an energy鈥慴urning pathway in mice has the potential to lead to new treatments for bone disease.
The study, published in , sheds new light on brown fat. Unlike white fat, which stores energy, brown fat cells burn calories, producing heat as a byproduct. For years, it was believed this process relied on a single pathway. More recently, researchers discovered a parallel pathway, but how it became activated remained a mystery.
