Three studies published this week in the New England Journal of Medicine find that 'brown fat' - a type found in babies - is actually present in adults as well, and has impressive calorie-burning powers.

Researchers say that finding a way to activate the calorie-burning properties of the brown fat could help combat obesity. We'll talk about it in this segment.
