If you need an alarm to get up in the morning, you're probably not getting enough sleep.
Biological clocks set the pace for nearly all living things, and Jeffrey Hall, Michael Rosbash and Michael Young – awarded the Nobel Prize in Physiology or Medicine – helped us understand how.
Americans Jeffrey Hall, Michael Rosbash and Michael Young share the 2017 Nobel Prize in Physiology or Medicine for work that explained how our cells keep track of time.
The winners of the Nobel Prize in Physiology or Medicine discovered how our internal body clock works.
