This Sunday, it's time for our annual Ig Nobel Awards celebration - the annual prize ceremony that celebrates research that spurs interest in science. 

The whole list of research can be found at Past Ig Winners (improbable.com) but among Dr Michelle Dickinson's favourites, the winners were: 

A team that showed how the hair on your head swirls in a different direction depending on whether you live in the northern or southern hemisphere. 

Research looking at how defrosted, dead fish swim. 

How placing a cat on the back of a cow and then popping bags every 10 seconds to stress out a cow might affect its milk production. 

How some mammals (including humans) can breathe through their bum!
