circadian clocks, cell & molecular biology

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. 

Research in human patients and mice reveals the role of the circadian clock in the risk of heart damage at different times of day.

Across many diseases, taking medication at specific times of day may make the therapy more effective.

The body's rhythms could affect numerous ailments as well as how people respond to treatments.

Scientists determine how the brain’s central clock regulates drinking prior to sleep in rodents.

Metabolic activity, not light, drives the circadian clock in cyanobacteria.

Evening consumption of the drug leads human circadian rhythms to lag.

The timing of meals affects the levels of lipids in the livers of mice, according to a study.

Mistimed sleep disrupts human transcriptome; canine tumor genome; de novo Drosophila genes; UVA light lowers blood pressure; aquatic microfauna fight frog-killing fungus

Why eating at the wrong times is tied to such profound and negative effects on our bodies

Many of the body's tissues can tell time, and these peripheral clocks can be influenced by environmental cues, such as the timing of food consumption.

The eating schedule—and not the amount of calories—can make the difference between an obese, diabetic, sick mouse and one with a healthy metabolism.

With persistence and pluck, Leslie Vosshall managed to snatch insect odorant receptors from the jaws of experimental defeat.

Researchers identify the first circadian clock component conserved across all three domains of life.

Fly circadian behavior is dramatically different in natural environments than in the lab.

The behavior of skin stem cells is regulated by a 24-hour circadian clock.

Researchers identify a gene that wakes people up from sleep each day.

The neural nexus of the circadian clock shows signs of functional decline as mice age, providing clues as to why sleep patterns tend to change as people grow older.
