012 - Natural history collections with James Maclaine and Andrew Stewart

Natural history collections, huge archives of carefully curated specimens, are an invaluable tool for the scientific community. They are also a place where the public get to interact with active research and meet scientists. Forget what you’d imagine working in a museum to be like, no two days are the same and both the collections and the talented people who work with them are in constant demand. One day your helping design new swimwear based on shark skin, the next settling an argument at a fishing competition.

If you’re wondering what jobs are out there in science or just curious to know what goes on behind the scenes at a museum, this episode has some surprises for you.

 

Alan is still away at sea, so Thom is joined again by Dr Heather Ritchie to tacked some deep-sea news, seabed mapping, secrets revealed by snailfish genes and wandering sponges are all hot off the presses. Don also drops in with an example of when you don’t want to collect biology, on the hull of your vessel as biofouling.
