The story of the word

Physiologists used the word for shivering and brown fat long before supplement labels borrowed it. Brown adipose tissue burns fuel without doing any mechanical work, which is how a newborn stays warm and how hibernating mammals rewarm. The same θερμός sits on every vacuum flask: Thermos was registered as a trade name in 1904 and became the common word for the object.
