This week? We're so lazy it's killing us. Also, go figure: extreme weather events leads to an increase in belief in climate change. And dolphins might be using some awesome maths when finding fish for dinner.

Chris & Tilly, back with fresh pantaloons! No Higgs boson news this week. Instead? Australian boys to get Gardasil. Also: magnetic fish noses, and watching salmon evolve. Very ichthyological, this episode.
