Glowing, blinking bacteria reveal how cells synchronize biological clocks
Biologists have long known that organisms from bacteria to humans use the 24 hour cycle of light and darkness to set their biological clocks. But exactly how these clocks are synchronized at the molecular level to perform ...

1st large-scale map of a plant's protein network addresses evolution, disease process
The eon-spanning clock of evolution – the millions of years that generally pass before organisms acquire new traits – belies a constant ferment in the chambers and channels of cells, as changes in genes and proteins ...

Plant clock gene also works in human cells
A gene that controls part of the 'tick tock' in a plant's circadian clock has been identified by UC Davis researchers. And not only is the plant gene very similar to one in humans, but the human gene can work in plant cells ...

MicroRNAs grease the cell's circadian clockwork
Most of our cells possess an internal clock, a group of genes displaying a cyclic expression pattern that reaches a peak once a day. A large number of circadian genes are expressed by organs such as the liver, whose activity ...
