(QHA) - A week of Nobel Prize announcements has begun in Sweden with the prize for physiology or medicine. The 2013 Nobel Prize in medicine was awarded Monday to three Americans - James E. Rothman, Randy W. Schekman and German-born Thomas C. Sudhof - for their discoveries of machinery regulating a major transport system in the body's cells, World bulletin informs. Monday's ceremony will be followed by the announcement of the physics prize on Tuesday, the chemistry prize Wednesday and the economics prize on October 14. The Nobel Prize in medicine administered by the Nobel Foundation is awarded once a year for outstanding discoveries in the fields of life sciences and medicine. Each prize comes with 8 million Swedish kronor ($1.2 million). As reported, the most anticipated prize -- for peace -- will be announced on October 11 in Oslo. To be noted, among the favorites for that award is the Pakistani teenage activist Malala Yousafzai, who was shot in the head by the Taliban last year for demanding education for girls.
