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

A team of researchers from iMM Lisboa led by Luísa Figueiredo and in collaboration with Joe Takahashi's group from Southwestern University has shown for the first time that the parasite responsible for sleeping sickness, ...

What marine midges can tell us about clocks and calendars

The non-biting marine midge Clunio marinus lives along Europe's tide-shapen coasts, where precise timing is of existential importance: Reproduction and oviposition must occur when the tide is at its lowest. The tides, and ...

Ancient proteins shown to control plant growth

A UCLA-led international team of life scientists reports the discovery of mechanisms regulating plant growth that could provide new insights into how the mammalian biological clock affects human health. The research will ...

Blast of thin air can reset circadian clocks

We might not think of our circadian clock until we are jetlagged, but scientists continue to puzzle over what drives our biological timepiece. Now, a study published October 20 in Cell Metabolism has found that variations ...

An appetite suppressant with side effects

Neurogeneticists from the University of Würzburg have discovered a peptide in Drosophila that has a strong impact on the fly's feeding and sleeping habits. At the same time, it is associated with the insects' circadian clock.

Light causes drosophila to take longer midday nap

Fruit flies' activity peaks in the morning and late afternoon. The insects extend their midday siesta on long summer days. Researchers from the University of Würzburg have now discovered what triggers this behaviour. A miniature ...
