The Annals of Improbable Research has announced the winners of the 2007 Ig Nobel Prize, awarded Thursday night (October 4) at Harvard’s Sanders Theatre.

The Ig Nobels honor the contributions of off-beat scientists to humanity’s off-beat knowledge, or at least major contributions to humanity’s fine-tuned sense of the completely absurd. For instance, this years’ Ig Nobel Prize for Peace was awarded to the U.S. Air Force’s Wright Laboratory in Dayton, Ohio, for research into a chemical weapon designed to make enemy soldiers become irresistible to each other – the “Gay Bomb.”

No, the Air Force neglected to send any of its prize-winning researchers to Cambridge to formally accept the Prize. Reminds me of a line Tommy Lee Jones delivered in Men In Black, with liberties…

“We in the Air Force do not have a sense of humor that we are aware of.” Luckily the sciencey-types at MIT do have a sense of humor.

I was particularly intrigued by the world’s first comprehensive study of injuries that are caused by sword-swallowing. Since one of the authors of the study is himself a sword-swallower, he did know a little bit about what to look for. Your basic throat abrasions, perforated esophagi and punctured blood vessels.

The Ig Nobel Prize for Nutrition went to Cornell professor Brian Wansink, who established once and for all that Americans judge when they’re full with their eyes instead of their stomachs. In order to establish this, Wansink designed some clever soup bowls with hidden tubes which slowly refilled them as the diner ate. Turns out the diners managed to eat nearly 75% more soup at the sitting, even though they reported not feeling any more full than if they’d eaten a regular bowl of soup. No wonder Americans are obese!

Supersizing works.

Another Ig Nobel went to a Japanese researcher who developed a method of extracting vanilla flavoring from cow dung. Yum! And a group of Spanish scientists found that rats sometimes can’t tell the difference between the Japanese and Dutch languages – if they’re spoken backwards.
