The Prize for Medicine went to researchers who found that roller coaster rides could help dislodge kidney stones, while a Japanese gastroenterologist won a Medical Education Prize for performing a colonoscopy on himself while sitting. (He reported “Mild discomfort”.) The Chemistry Prize went to researchers who found that saliva worked better on 18th-century sculpture than alcohol-based cleaners, and researchers who found that workers did in fact relieve stress by sticking pins in voodoo dolls of their bosses won the Economics Prize.
