The 2017 Nobel Prize in Physiology or Medicine has been awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young "for their discoveries of molecular mechanisms controlling the circadian rhythm".
Circadian rhythms, the body’s inner clock, adapt one's physiology to different phases of the day, influencing sleep, behavior, hormone levels, body temperature and metabolism.
"Their discoveries explain how plants, animals and humans adapt their biological rhythm so that it is synchronized with the Earth’s revolutions", said the Nobel Assembly at Sweden's Karolinska Institute. “Using fruit flies as a model organism, this year’s Nobel laureates isolated a gene that controls the normal daily biological rhythm. They showed that this gene encodes a protein that accumulates in the cell during the night, and is then degraded during the day. Subsequently, they identified additional protein components of this machinery, exposing the mechanism governing the self-sustaining clockwork inside the cell."
Medicine is traditionally the first of the Nobel prizes awarded each year. It will be followed in the coming days by announcements for prizes in Chemistry, Physics, Literature, Peace and Economics.
