Oct 8 - Stem cell researchers Mario Capecchi, Martin Evans and Oliver Smithies won the 2007 Nobel prize for medicine or physiology

The prize awarders said the discoveries made by the three have led to a new branch of medicine known as gene targeting. This enables certain genes to be turned off "allowing scientists to establish the roles of individual genes in health and disease".
