McGill University scientists report that glycerol released during cold-induced fat breakdown can activate the enzyme tissue-nonspecific alkaline phosphatase (TNAP), switching on a creatine-based energy-dissipating pathway in brown fat. The findings were published May 12, 2026 in Nature and may also inform research into bone disorders linked to TNAP.
