The 2017 Nobel Prize in Physiology or Medicine was awarded to Jeffrey C. Hall, Michael Rosbash and Michael W. Young for their work on mechanisms controlling the circadian rhythm, the Nobel Assembly said Monday, Sputnik News reports.

The Nobel Assembly noted that the doctors managed to discover how humans, plants, and animals adapt their biological rhythms to changes in the environment which have been taking place over the centuries.

“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. We now recognize that biological clocks function according to the same principles in cells of other multi-cellular organisms, including humans,” the Nobel Assembly added.
