3 U.S born scientists win Nobel Prize in Medicine.

Three U.S.-born scientists Jeffrey Hall, Michael Rosbash and Michael Young won the 2017 Nobel Prize in Medicine on Monday for unravelling molecular mechanisms that control our internal body clocks.

Chronobiology(the study of biological clocks) is now a popular and growing field of research thanks to the pioneering work of the three scientists, who explained the role of specific genes in keeping animal bodies in step with light and darkness.

The mechanisms help explain how people experience jet lag when their internal circadian rhythms get out of sync, while also having wider implications for disorders ranging from insomnia to depression to heart disease.

Michael Rosbash is a professor at Brandeis University in Waltham, Mass., Jeffrey Hall is also on the faculty at Brandeis and is associated with the University of Maine. Michael Young is a professor at New York’s Rockefeller University.
