Under constant darkness, Drosophila’s ability to form lasting memories is impaired.

The plant geneticist has revolutionized researchers’ understanding of how light affects plant growth and development, and is engineering plants to combat climate change.

As global temperatures rise and winters shorten, caterpillars of the corn borer moth are emerging earlier in parts of the US thanks to changes in two genes, researchers find.

The diurnal cycles of the microbiome alter the activity of a protein produced by the host, and in turn guide histone acetylation, gene expression, and metabolic activity.

Circadian rhythms heavily influence how our bodies use energy, a small study suggests.

Timekeepers in muscle help mediate metabolism, and may influence neurological processes such as sleep.

Just 20 years ago, scientists didn’t even realize muscles had their own circadian clocks. Now they are beginning to appreciate their importance in health. 

Even in mice with a busted circadian clock and an unhealthy diet, carefully timed feeding overcomes the rodents’ predispositions for metabolic diseases.

In Drosophila, the tissue is more permeable to drugs at night, offering a possible explanation for why some medicines work better at certain times of day.
