New research shows chameleons actively tune nano-crystals to change their color. For a 10-day free trial, check out http://lynda.com/veritasium Chameleon research in Nature Communications: http://bit.ly/1FacHO2 "Photonic Crystals Cause Active Colour Change in Chameleons" This research was carried out by Jérémie Teyssier, Suzanne V. Saenko, Dirk van der Marel & Michel C. Milinkovitch at the University of Geneva Department of Quantum Matter Physics and the Laboratory of Artificial and Natural Evolution (LANE) Original videos of chameleons are here: https://www.youtube.com/watch?v=YIRiCwHlUd8 https://www.youtube.com/watch?v=XdQvtP8EKrM https://www.youtube.com/watch?v=YSH7EmXFMac https://www.youtube.com/watch?v=egwueh6wj1E Additional details available at: http://www.lanevol.org/LANE/chameleon_colour_change.html For correspondence: Michel C.
