Eureka Prizes for science, science of spaghetti breaking and rosehip neurons

This week on the show Claire gives a round up of the highlights of the Eureka Prizes for science, or as we like to affectionately call them, the 'Archies'. Chris brings a tasty scientific question into the studio that has been plaguing physicists for years - why does spaghetti break in 3 parts? And Stu talks about a new neuron that has just been discovered, the rose-hip neuron!
