It's been a while since I noted one of my favorite lists. I'm rectifying that omission now.

PHYSICS PRIZE — For testing the biological principle that nearly all mammals empty their bladders in about 21 seconds (plus or minus 13 seconds).
Patricia Yang [USA and Taiwan], David Hu [USA and Taiwan], and Jonathan Pham, Jerome Choo [USA]
LITERATURE PRIZE — For discovering that the word "huh?" (or its equivalent) seems to exist in every human language — and for not being quite sure why.

MATHEMATICS PRIZE — For trying to use mathematical techniques to determine whether and how Moulay Ismael the Bloodthirsty, the Sharifian Emperor of Morocco, managed, during the years from 1697 through 1727, to father 888 children.
Elisabeth Oberzaucher [Austria, Germany, U.K.] and Karl Grammer [Austra, Germany]
BIOLOGY PRIZE — For observing that when you attach a weighted stick to the rear end of a chicken, the chicken then walks in a manner similar to that in which dinosaurs are thought to have walked.
Bruno Grossi, Omar Larach, Mauricio Canals, Rodrigo A. Vásquez [Chile], José Iriarte-Díaz [Chile, USA]
DIAGNOSTIC MEDICINE PRIZE — For determining that acute appendicitis can be accurately diagnosed by the amount of pain evident when the patient is driven over speed bumps.

PHYSIOLOGY and ENTOMOLOGY PRIZE — For carefully arranging for honey bees to sting him repeatedly on 25 different locations on his body, to learn which locations are the least painful (the skull, middle toe tip, and upper arm). and which are the most painful (the nostril, upper lip, and penis shaft).
Awarded jointly to two individuals: Justin Schmidt [USA, Canada], for painstakingly creating the Schmidt Sting Pain Index, which rates the relative pain people feel when stung by various insects; and to Michael L. Smith [USA, U.K., The Netherlands]
