12 Mar 2015, Germany — Biologist Stefan Lanka talks to the media outside the district court in Ravensburg, Germany, 12 March 2015. Lanka had challenged the idea of pathogenic measles viruses promising an award of 100,000 euro for anyone who could give proof of the contrary. A physician from the state of Saarland had delivered the proof, according to his own statement. Lanka, however, refused to pay.
