How circadian clocks communicate with each other

Multiple biological clocks control the daily rhythms of physiology and behavior in animals and humans. Whether and how these clocks are connected with each other is still a largely open question. A new study now shows that ...

New light sensing molecule discovered in the fruit fly brain

Six biological pigments called rhodopsins play well-established roles in light-sensing in the fruit fly eye. Three of them also have light-independent roles in temperature sensation. New research shows that a seventh rhodopsin, ...

No mid-day nap for northern flies

Fruit flies from warm regions have a siesta, whereas their Nordic counterparts do not. Biologists from the University of Würzburg reset the circadian clock of African flies in an experiment. As a result, these insect also ...

Tick tock: Time to sleep? Sleeping parasite has own internal clock
