Nobel week begins with medicine prize

Nobel season kick offs Monday with the 2018 Nobel Prize in Physiology or Medicine being awarded.

The laureate or laureates will be revealed by the Nobel Assembly at the Karolinska Institute in Stockholm.

Last year's prize was won by Jeffery C. Hall, Michael Rosbash and Michael W. Young for their discoveries about how the biological clock of humans and other living organisms works.

108 prizes in physiology or medicine have been awarded since 1901 and on nine occasions no prize was handed out.
