Nearly 60 years ago, a French town was hit by a sudden outbreak of hallucinations, which left five people dead and many seriously ill. For years it was blamed on bread contaminated with a psychedelic fungus - but that theory is now being challenged.
Barry Marshall changed the face of medical science when he swallowed a petri-dish of dangerous bacteria to prove it caused stomach ulcers. His theory meant that they could be treated with a simple anti-biotic rather than expensive surgery. Dr Marshall also claimed that his research continues to save up to 500,000 lives per year.
The collaboration behind the finding in September that neutrinos may travel faster than light has carried out an improved version of their experiment - and found the same result. If confirmed by other experiments, the find could undermine one of the basic principles of modern physics.
