Dog testicles, penguin poop study win Ig Nobels 

令人大笑发人深省 第15届“搞笑”诺贝尔奖揭晓  
 
 
Psychologist and author Robin Abrahams (L) talks to William Lipscomb, winner of the 1976 Nobel Prize in Chemistry and dressed as a bottle of beer, at the 'Fifteenth 1st Annual Ig Nobel Prize' ceremony at Harvard University in Cambridge, Massachusetts October 6, 2005.

The spoof prizes, awarded by the science humor magazine Annals of Improbable Research, are presented at a ceremony in Cambridge, Massachusetts, where the winners must try to explain their work in a minute or less.

While some awards clearly poke fun at current culture, others are meant to provoke debate about science, Annals editor Marc Abrahams said.

"Now in their fifteenth year, the Igs honor achievements that first make people laugh, and then make them think," Abrahams said in a statement.

The Ig Nobel Prizes were handed to the winners by genuine Nobel laureates Dudley Herschbach (1986 Chemistry), William Lipscomb (1976 Chemistry), Robert Wilson (1978 Physics) and Sheldon Glashow (1979 Physics).

Harvard professor Roy Glauber, awarded a Nobel Prize in physics, has been a regular at the Ig Nobels for 10 years, sweeping paper airplanes thrown on the stage during the ceremony.

This year's winners include:

"Medicine" -- Gregg Miller of Oak Grove, Missouri, for inventing Neuticles -- artificial replacement testicles for dogs.

"Fluid Dynamics" -- Victor Benno Meyer-Rochow of International University Bremen, Germany and Jozsef Gal of Lorond Eotvos University in Hungary, for "Pressures Produced When Penguins Pooh -- Calculations on Avian Defecation," an actual study published in 2003 in the journal Polar Biology.
