Epigenetic ‘Clocks’ Predict Animals’ True Biological Age
A statistical analysis of chemical tags on DNA may help unify disparate theories of aging.
The Body’s Clock Offers a Rhythmic Target to Viruses
Viruses and other parasites may sync with their host’s biological clock — or reset it — to gain an advantage.
The Overlooked Link Between Two of This Year’s Nobel Prizes
To better understand the molecules described by the latest prize in medicine, we will need the technique recognized by the latest prize in chemistry.
Nobel Prize Awarded for Biological Clock Discoveries
Three U.S. biologists share the Nobel Prize in Medicine for their research into the molecular mechanism that drives circadian rhythm.
How Circadian Clocks Differ From Sleep
The circadian clock is in nearly every cell, and researchers have untangled many of its secrets. But sleep has been harder to pin down.
Researchers Tap a Sleep Switch in the Brain
Powerful new experiments have uncovered some of the molecular underpinnings of sleep.
Teeth May Reveal a Multi-Day Biological Clock
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.
The Beasts That Keep the Beat
New insights from neuroscience — aided by a small zoo’s worth of dancing animals — are revealing the biological origins of rhythm.
How the Body’s Trillions of Clocks Keep Time
Cellular clocks are almost everywhere. Clues to how they work are coming from the places they’re not.
