Scientists Discover Hidden Molecular Switch That Could Strengthen Bones

Scientists at McGill University have discovered a hidden molecular “switch” that activates a powerful calorie-burning system in brown fat, a breakthrough that could pave the way for new treatments for bone diseases and metabolic disorders. The findings, published in the journal Nature, reveal how glycerol — a molecule released when fat is broken down during cold exposure — activates an enzyme called TNAP, triggering an alternative heat-producing mechanism in brown fat that scientists ha...
