“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)

  1. So the specific structure of those tiny crystals causes them to absorb every color except for blue. While that's fascinating, isn't that exactly the same the red and yellow pigments do with red and yellow light?

  2. great bro…thanks for sharing truth… and i have a request ..could you please explain about your realisation on metaphysics… i am curious and exicted to know from you… !!

  3. That's so much cooler than pigments imo, it's like every chameleon has a million little tunable microwave cavities under their skin, except for visible light (I know, that's not the same exact mechanism).
