Circuits in the brain act as an internal clock to tell us it is time to sleep and to control how long we then stay asleep. A new study in flies suggests a part of that clock constantly monitors ...

Most biochemical reactions accelerate as temperature increases, but our daily circadian rhythms, which are underlain by gene regulatory and biochemical networks, remain constant, even as temperatures ...

One important aspect of the internal time-keeping system continues to perplex scientists: its complex response to temperature, which can shift the clock forward or backward, but cannot change its ...

Life on Earth, from bacteria to animals, has evolved internal timekeeping systems that generate circadian rhythms in numerous physiological processes and behaviors, enabling adaptation to the ...

The protein IR25a is best known for its role as an odour receptor in flies, but an analysis reveals that it also acts to synchronize the circadian clock by sensing small temperature fluctuations. See ...
