Animals use their muscles to shiver to generate heat when exposed to the cold. But this is a short-term adaptation. Long term, it is believed the body relies on the brown adipose tissue (BAT) to generate heat in a nonshivering fashion. New work from Muthu Periasamy and colleagues challenge this BAT-centric view by showing that the muscle is also a key site of nonshivering thermogenesis.
