Braving the cold to understand what makes squirrels tick

The circadian clock of arctic ground squirrels works differently during the cold of hibernation, new research shows.

During this period of torpor, many bodily functions are suppressed to conserve energy, including the daily clock known as the circadian clock. A new study asks the question, do circadian clocks persist throughout torpor?
