The circadian rhythm research that just won a Nobel prize in medicine, explained
The award celebrates the study of the tiny biological clocks in every living thing.
Three American scientists have won the Nobel Prize in physiology or medicine for their discoveries of the microscopic biological machinery that controls the circadian rhythm, or the 24-hour body clock.
Humans, plants, and animals are all ruled by an internal clock that runs on a 24-hour, light-dark cycle in sync with the sun. And there’s not just one of these clocks inside us: They’re in every single cell of every organism — from a tiny bacterium to a large redwood tree.
In humans, these biological clocks anticipate various activities throughout the day, from waking up to sleeping and eating, by regulating things like hormone levels, temperature, and metabolism. Our circadian rhythm is intimately tied to our health and well-being (which helps explain why jet lag or a late-night shift work can be so draining and harmful).
The three Nobel laureates — Jeffrey C. Hall of the University of Maine, Michael Rosbash of Brandeis University, and Michael W. Young of Rockefeller University — “were able to peek inside our biological clock and elucidate its inner workings,” the Nobel Prize Committee said in a press release. “Their discoveries explain how plants, animals, and humans adapt their biological rhythm so that it is synchronized with the Earth's revolutions.”
