The Ig Nobel Prizes honour achievements that first make us laugh, then make us think. We take a look at this year’s winners: from rollercoaster medicine to Voodoo in the workplace!

Chinese scientists report editing the genome of human embryos, the role of oxytocin in human/dog relations, chimps that hunt with spears, unexpected bacterial complications in organ transplants, another magma chamber found at the Yellowstone supervolcano and celebrating 25 years of Hubble.

Total solar eclipse experiences, a planet without a star, and the bacteria in your belly button. Plus great apes with mid-life crises, nasal hope for paralysed dogs and a rant about speculation in the media. Also, the Bdelloid Rotifer: 80 million years without sex and still genetically diverse.

All the fun from the 2012 Ig Nobel awards! Ponytails, SpeechJammer, coffee, dead salmon, the Eiffel Tower and more!
