This week, we learn about how pigeon racing can bridge the generational gap, and hear the sounds of migratory monarch butterflies flap as they journey across North America. And, on the subject of insects - how many flies have existed in the world for all time? Plus, as the election post-mortem begins, how does a botanist get involved in crime forensics?
