'Why Banana Skins Are Slippery' Wins IgNobel

gbjbaanb writes: This year's Ig Nobel prize was won by Japanese researchers investigating why banana skins produced a frictionless surface compared to apple and orange peels. (Apparently, "The polysaccharide follicular gels that give banana skins their slippery properties are also found in the membranes where our bones meet," so its not all fun and jollity). Other prizes were awarded for noting that dogs only defecate when aligned with north-south magnetic fields, and that "night owl" people are more likely to be psychopaths than early risers. Yes, that probably includes you.
