Ig Nobel Prize Winners for 2010

The tongue-in-cheek Ig Nobel awards for "improbable research" have become almost as famous as the real Nobels. The awards are run by the science humour magazine Annals of Improbable Research. They are supposed to "first make people laugh, and then make them think". Here is a picture of the prize, no money is won (unlike the Nobel Prizes).
All the research, bar some special prizes, is real and published in bona fide academic journals. As part of the fun, the prizes are also handed over by genuine Nobel Laureates.
The full list of winners:
Engineering Prize: Karina Acevedo-Whitehouse (UK) and colleagues for perfecting a method to collect whale snot, using a remote-control helicopter.
Medicine Prize: Simon Rietveld (Netherlands) and colleagues for discovering that symptoms of asthma can be treated with a roller-coaster ride.
Transportation Planning Prize: Toshiyuki Nakagaki (Japan) and colleagues for using slime mould to determine the optimal routes for railroad tracks.
Physics Prize: Lianne Parkin (New Zealand) and colleagues for demonstrating that, on icy footpaths in wintertime, people slip and fall less often if they wear socks on the outside of their shoes.
Peace Prize: Richard Stephens (UK) and colleagues for confirming the widely held belief that swearing relieves pain.
Public health Prize: Manuel Barbeito (US) and colleagues for determining by experiment that microbes cling to bearded scientists.
Economics Prize: Awarded to the executives and directors of Goldman Sachs, AIG, Lehman Brothers, Bear Stearns, Merrill Lynch, and Magnetar for creating and promoting new ways to invest money — ways that maximize financial gain and minimize financial risk for the world economy, or for a portion thereof.
Chemistry Prize: Eric Adams (US) and colleagues for disproving the old belief that oil and water don't mix. The research, supported by BP, was published under the title: "Review of Deep Oil Spill Modeling Activity Supported by the Deep Spill JIP and Offshore Operator's Committee".
Management Prize: Alessandro Pluchino (Italy) and colleagues for demonstrating mathematically that organisations would become more efficient if they promoted people at random.
Biology Prize: Libiao Zhang (China) and colleagues for scientifically documenting fellatio in fruit bats.
