Separating morning and evening in the circadian clock of mammals

Work by researchers at the universities of Aberdeen and Nottingham suggest an anatomical basis for the adaptation of the mammalian circadian clock to changing day-length.
Endogenous circadian clocks ensure that temporal patterns of physiology and behavior predict environmental changes determined by the Earth’s rotation and orbit of the Sun. Such clocks are synchronized by the daily light-dark cycle.
