Prions and the Experts

A controversial paper suggests that prions, particular proteins, may not be the cause for mad cow disease or scrapie. Well, that's a quite provoking news, because the prion hypothesis won a Nobel Prize, and then became a dogma. The point is, what the fellow experts think. Aren't they convinced or sure of their evidence? "Experts contacted by Nature Medicine declined to comment on the controversial paper," writes Micheal Hopkin in Nature Medicine (27.4.2006). Strange.
