Two Americans and a British scientist have been awarded the Nobel prize in medicine for their groundbreaking work on blood-borne hepatitis, a health problem that causes cirrhosis and liver cancer around the world.
Harvey J Alter at the US National Institutes of Health in Maryland, Charles M Rice from Rockefeller University in New York, and Michael Houghton, a British virologist at the University of Alberta in Canada, were honoured for their joint discovery of the hepatitis C virus, a major cause of liver disease.
The award may prove controversial as Houghton recently turned down a major prize because it excluded two co-workers at the pharmaceutical firm Chiron who helped him identify the virus. In 2013, he refused the Canada Gairdner international award sometimes known as the “baby Nobel” because it did not recognise the work of his former colleagues George Quo and Qui-Lim Choo.
