Two French scientists who discovered the AIDS virus and a German who bucked conventional wisdom to find a virus that causes cervical cancer were awarded the 2008 Nobel prize for medicine on Monday October 6, 2008. Luc Montagnier, director of the World Foundation for AIDS Research and Prevention, and Francoise Barre-Sinoussi of the Institut Pasteur won half the prize of 10 million Swedish crowns ($1.4 million) for discovering the virus that has killed 25 million people since it was identified in the 1980s.
