Ig Nobel Prizes Highlight Excellence in Improbable Research

On the toes of this year’s Nobel Prizes (see a post about the 2008 Nobel Prize in Physiology or Medicine later today) , the Ig Nobel Prizes–for “achievements that first make people LAUGH then make them THINK”–have been announced last week, and here is a selection of winners that we thought to be relevant to our audience:

MEDICINE PRIZE. Dan Ariely of Duke University (USA), Rebecca L. Waber of MIT (USA), Baba Shiv of Stanford University (USA), and Ziv Carmon of INSEAD (Singapore) for demonstrating that high-priced fake medicine is more effective than low-priced fake medicine.
REFERENCE: “Commercial Features of Placebo and Therapeutic Efficacy,” Rebecca L. Waber; Baba Shiv; Ziv Carmon; Dan Ariely, Journal of the American Medical Association, March 5, 2008; 299: 1016-1017.

BIOLOGY PRIZE. Marie-Christine Cadiergues, Christel Joubert, and Michel Franc of Ecole Nationale Veterinaire de Toulouse, France for discovering that the fleas that live on a dog can jump higher than the fleas that live on a cat.
REFERENCE: “A Comparison of Jump Performances of the Dog Flea, Ctenocephalides canis (Curtis, 1826) and the Cat Flea, Ctenocephalides felis felis (Bouche, 1835),” M.C. Cadiergues, C. Joubert, and M. Franc, Veterinary Parasitology, vol. 92, no. 3, October 1, 2000, pp. 239-41.

PHYSICS PRIZE. Dorian Raymer of the Ocean Observatories Initiative at Scripps Institution of Oceanography, USA, and Douglas Smith of the University of California, San Diego, USA, for proving mathematically that heaps of string or hair or almost anything else will inevitably tangle themselves up in knots.
REFERENCE: “Spontaneous Knotting of an Agitated String,” Dorian M. Raymer and Douglas E. Smith, Proceedings of the National Academy of Sciences, vol. 104, no. 42, October 16, 2007, pp. 16432-7.

CHEMISTRY PRIZE. Sharee A. Umpierre of the University of Puerto Rico, Joseph A. Hill of The Fertility Centers of New England (USA), Deborah J. Anderson of Boston University School of Medicine and Harvard Medical School (USA), for discovering that Coca-Cola is an effective spermicide, and to Chuang-Ye Hong of Taipei Medical University (Taiwan), C.C. Shieh, P. Wu, and B.N. Chiang (all of Taiwan) for discovering that it is not.
REFERENCE: “Effect of ‘Coke’ on Sperm Motility,” Sharee A. Umpierre, Joseph A. Hill, and Deborah J. Anderson, New England Journal of Medicine, 1985, vol. 313, no. 21, p. 1351.
REFERENCE: “The Spermicidal Potency of Coca-Cola and Pepsi-Cola,” C.Y. Hong, C.C. Shieh, P. Wu, and B.N. Chiang, Human Toxicology, vol. 6, no. 5, September 1987, pp. 395-6.

NUTRITION PRIZE. Massimiliano Zampini of the University of Trento, Italy and Charles Spence of Oxford University, UK, for electronically modifying the sound of a potato chip to make the person chewing the chip believe it to be crisper and fresher than it really is.
REFERENCE: “The Role of Auditory Cues in Modulating the Perceived Crispness and Staleness of Potato Chips,” Massimiliano Zampini and Charles Spence, Journal of Sensory Studies, vol. 19, October 2004, pp. 347-63.
