Episode 11: Eggs to live birth - how pregnancy evolved, Alzheimer's link with iron deposits, bonobos don't overimitate, and Cassini's grand finale

Summary: This fortnight Jesse and Sophie have a special selection of science news, plucked from all over town in this, their penultimate episode. In their first ontogenetic episode yet, they chat about breaking news from Yale on the evolution of pregnancy in marsupials and eutherians (ourselves), childhood learning in apes (bonobos' inability to copy silly stuff), a chat with Dr Olivier Salvado about iron deposits' relationship with Alzheimer's, and finally the living funeral of NASA's Cassini as it plummets into the Saturnian atmosphere - and you're invited!
