Three Americans win Nobel Prize for Medicine for discoveries about body's daily rhythms

Three Americans, namely Jeffrey C. Hall, Michael Rosbash and Michael W. Young, won the 2017 Nobel Medicine Prize for their work on internal biological clocks known as the circadian rhythm, the jury said on Monday.

"Their discoveries explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth's revolutions," the Nobel Assembly said.

Rosbash is on the faculty at Brandeis University, Young at Rockefeller University and Hall is at the University of Maine.

The citation for the 9-million-kronor ($1.1 million) prize says the researchers isolated a gene that controls the normal daily biological rhythm. They "were able to peek inside our biological clock and elucidate its inner workings."

Circadian rhythms adapt one's physiology to different phases of the day, influencing sleep, behavior, hormone levels, body temperature and metabolism.
