About this episode

This episode explores the faint glow emitted by living things and questions the cleanliness of the International Space Station.

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 For show transcripts, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠vox.com/unxtranscripts⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ For more, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠vox.com/unexplainable⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ And please email us! ⁠⁠⁠unexplainable@vox.com⁠⁠⁠ We read every email.
