2015 Ig Nobel prizes: dinosaur-like chickens and bee-stings to the penis

Awards parodying Nobel prizes given out for most unusual or trivial achievements in scientific research

A man stung dozens of times by bees, mathematicians who wanted to know whether a man could physically be able to sire 600 sons, and chemists who unboiled an egg were honoured on Thursday night with one of science's most storied awards, the Ig Nobel prize.

Professors, researchers, students and actual Nobel laureates from around the world gathered at Harvard University at the 25th First Annual Ig Nobel Prize Ceremony, the absurdist celebration of science that "makes you laugh, then think".
