Every month, Nerd Nite gathers smart speakers and a curious crowd to facilitate a thought-provoking discussion on a monthly-changing topic. This April, they’re going underground in search of volcanoes and fossils.

First, University of Tokyo professor Ryuichi Nishiyama will be exploring volcanoes using high-tech muography. Then University of Tsukuba paeleontologist Emma Dangerfield will be making sure that badgers get their moment in the limelight.

Both alcoholic and non-alcoholic drinks will be available.
