A German biologist who offered 100,000 (71,350; $106,300) to anyone who could prove that measles is a virus has been ordered by a court to pay up.

Stefan Lanka, who believes the illness is psychosomatic, made the pledge four years ago on his website.

The reward was later claimed by German doctor David Barden, who gathered evidence from various medical studies. Mr Lanka dismissed the findings.
Lanka's said he will appeal.
