X-Ray Earth, a new documentary series on the National Geographic Channel, is expected to re-air an episode featuring the urbanization and city scaling work of SFI External Professor Luis Bettencourt and Distinguished Professor Geoffrey West on Wednesday, May 18, at 6:00 p.m. MST. The episode first aired on May 15. 

The show's promotional summary: "Similar to the way doctors use X-rays to diagnose unseen medical problems, scientists are using an army of sensors located underground, in the sky, in the ocean, and in our cities to monitor the Earth more than at any other time in our history. From the undisturbed far reaches of the planet to the busiest cities on the globe, X-RAY EARTH uses technology and CGI to give us a new view of our world."
