Chronobiology

Though they live only a few hours before dividing, bacteria can anticipate the approach of cold weather and prepare for it. The discovery suggests that seasonal tracking is fundamental to life.

European beech trees more than 1,500 kilometers apart all drop their fruit at the same time in a grand synchronization event now linked to the summer solstice.

In a year packed with fascinating discoveries, biologists pushed the limits of synthetic life, probed how organisms keep time, and refined theories about consciousness and emotional health.

For the first time, scientists have decoded the molecular structure of a protein that helps to sync a biological clock to the phases of the moon.

For decades, Carrie Partch has led pioneering structural research on the protein clockwork that keeps time for our circadian rhythm. Is time still on her side?

A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.

Viruses and other parasites may sync with their host’s biological clock — or reset it — to gain an advantage.

To better understand the molecules described by the latest prize in medicine, we will need the technique recognized by the latest prize in chemistry.

Three U.S. biologists share the Nobel Prize in Medicine for their research into the molecular mechanism that drives circadian rhythm.
