  London, October 2 (IANS) Three American scientists have won the the 2017 Nobel Prize in Physiology or Medicine for their discoveries of molecular mechanisms controlling the circadian rhythm, the prize committee said in a statement on Monday.   The scientists -- Jeffrey C. Hall, Michael Rosbash and Michael W. Young -- were able to peek inside the human biological clock and elucidate its inner workings.   "Their discoveries explain how plants, animals and humans adapt their biological rhythm so that it is synchronised with the Earth's revolutions," said the Nobel Assembly at Karolinska Institutet, in a statement.

Michael Young was born in Miami and worked at Rockefeller University.
