Today was the 22nd First Annual awarding of the Ig Nobel Prizes. The awards are organized by the magazine Annals of Improbable Research.   The awarding committee says the prizes are awarded to “honor achievements that first make people laugh, and then make them think. The prizes are intended to celebrate the unusual, honor the imaginative — and spur people’s interest in science, medicine, and technology.” Wikipedia however says the prizes are awarded to trivial achievements in scientific research. Here are a few of today’s honorees:

1. ANATOMY PRIZE: Frans de Waal [The Netherlands and USA] and Jennifer Pokorny [USA] for discovering that chimpanzees can identify other chimpanzees individually from seeing photographs of their rear ends.
REFERENCE: “Faces and Behinds: Chimpanzee Sex Perception” Frans B.M. de Waal and Jennifer J. Pokorny, Advanced Science Letters, vol. 1, 99–103, 2008.

2. NEUROSCIENCE PRIZE: Craig Bennett, Abigail Baird, Michael Miller, and George Wolford [USA], for demonstrating that brain researchers, by using complicated instruments and simple statistics, can see meaningful brain activity anywhere — even in a dead salmon.
REFERENCE: “Neural correlates of interspecies perspective taking in the post-mortem Atlantic Salmon: An argument for multiple comparisons correction,” Craig M. Bennett, Abigail A. Baird, Michael B. Miller, and George L. Wolford, 2009.
REFERENCE: “Neural Correlates of Interspecies Perspective Taking in the Post-Mortem Atlantic Salmon: An Argument For Multiple Comparisons Correction,” Craig M. Bennett, Abigail A. Baird, Michael B. Miller, and George L. Wolford, Journal of Serendipitous and Unexpected Results, vol. 1, no. 1, 2010, pp. 1-5.

3. CHEMISTRY PRIZE: Johan Pettersson [SWEDEN and RWANDA]. for solving the puzzle of why, in certain houses in the town of Anderslöv, Sweden, people’s hair turned green.

4. FLUID DYNAMICS PRIZE: Rouslan Krechetnikov [USA, RUSSIA, CANADA] and Hans Mayer [USA] for studying the dynamics of liquid-sloshing, to learn what happens when a person walks while carrying a cup of coffee.
