Biophotons: Living Things Emit Visible Light

Today on the show: a double feature — two mysteries in one episode. First, it seems like all living things emit a faint glow that disappears when they die. Then, is the International Space Station ... too clean?

Guests: Daniel Oblak, professor of physics at the University of Calgary; Rodolfo Antonio Salido Benítez, scientist at SPT Labtech

Links: Daniel's paper with mouse and leaf images; Rodolfo's paper on the ISS
