Yale University Professor James Rothman, 62, the co-awardee of the 2013 Nobel Prize for Medicine, pulls a medal over his head, which was given to him by his students, before speaking to a class at Yale in New Haven, Connecticut October 7, 2013. Students also encircled Rothman's podium with trophies ahead of his arrival in celebration of the award. Rothman was one of three U.S.-based scientists who won the Nobel medicine prize on Monday for plotting how vital materials such as hormones and brain chemicals are transported within cells and secreted to act on the body, giving insight into diseases such as diabetes and Alzheimer's. Americans Rothman, Randy Schekman, 64, and German-born Thomas Suedhof, 57, separately mapped out one of the body's critical networks that uses tiny bubbles known as vesicles to ferry chemicals such as insulin within cells. Medicine is the first of the Nobel prizes awarded each year. REUTERS/Michelle McLoughlin (UNITED STATES - Tags: HEALTH SCIENCE TECHNOLOGY)
