Sarah, Tom and Jack discuss the implications of the Australian Vaccination(-Skeptics) Network changing its name, why biochemistry stops fish from living too deep in the ocean, and 30,000 year-old frozen bacteria-sized viruses. Jargonauts lays into "oogenesis", and Tom has a show at the Melbourne International Comedy Festival! (The March 26th show is a special podcast audience meetup! Come along!)

Plus: robots doing surgery, dissecting eggs, testicle puns, and gargling oil.
