Americans Win Nobel Prize in Physiology or Medicine for Discoveries on Circadian Rhythms
Scientists share $11 million prize for research in the biological clocks of plants, animals and humans


STOCKHOLM—Three Americans won this year’s Nobel Prize in physiology or medicine for their discoveries of molecular mechanisms controlling biological rhythms.

Jeffrey C. Hall, Michael Rosbash and Michael W. Young received the prize for research that led to the understanding of how plants, animals and humans synchronize their biological clocks with the Earth’s revolutions.

The award, announced Monday by the Nobel committee in Stockholm, comes with a check for nine million Swedish kronor ($11.1 million).

Last year, the Medicine Prize was awarded to Japanese biologist Yoshinori Ohsumi for elucidating how the body’s cells deal with and recycle waste.
