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.
The circadian clock is in nearly every cell, and researchers have untangled many of its secrets. But sleep has been harder to pin down.
Powerful new experiments have uncovered some of the molecular underpinnings of sleep.
Tiny lines laid down by tooth enamel appear to reveal a previously unknown biological rhythm. If confirmed, the finding could help researchers understand why big animals grow slower — and live longer — than small ones.
New insights from neuroscience — aided by a small zoo’s worth of dancing animals — are revealing the biological origins of rhythm.
Cellular clocks are almost everywhere. Clues to how they work are coming from the places they’re not.
