Chameleons Have Nanocrystals In Their Skin

(Telegraph) Chameleons use tiny crystals in their skin to change colour, scientists have discovered. In a groundbreaking study that fundamentally alters our understanding of the lizard’s ability to switch hue, scientists found that nanocrystals in the lizards’ skin are tuned to alter the reflection of light. “We were surprised,” said Michel Milinkovitch, a biologist at the University of Geneva. “It was thought they were changing colour through ... pigments. The real mechanism is totally different and involves a physical process.” Click here to read more.
