The techniques have led to new insights into conditions including heart disease and cancer, as well as aiding the development of new therapies.Smithies, who began his BA in Chemistry in 1946, is the Excellence Professor of Pathology and Laboratory Science at the University of North Carolina at Chapel Hill School of Medicine. He is also an Honourary Fellow of Balliol.The announcement of the Medicine Award marks the start of the 2007 cycle of Nobel Prize winners, with the final awards revealed on October 15.
