(Japan Times) A Japanese doctor was recognized Thursday with an Ig Nobel prize, which honor comical but practical scientific studies, for devising the most comfortable colonoscopy technique by using himself as a test subject.

Akira Horiuchi, a 57-year-old head of the digestive disease center at Showa Inan General Hospital in Nagano Prefecture, received the prize for medical education at a ceremony at Harvard University.
