A portrait of the 2016 Nobel Medicine Prize winner Yoshinori Ohsumi of Japan is displayed during a press conference to announce the winner of the 2016 Nobel Prize for Physiology or Medicine 2016 at the Nobel Forum in Stockholm on October 3, 2016. Yoshinori Ohsumi of Japan won the 2016 Nobel Medicine Prize for his work on autophagy -- a process whereby cells "eat themselves" -- which when disrupted can cause Parkinson's and diabetes, the jury said. The 2016 Nobel prize season kicks off with the announcement of the medicine prize by a scandal-tainted jury, to be followed over the next 10 days by the other science awards and those for peace and literature. / AFP PHOTO / JONATHAN NACKSTRAND
