Scientists discover that Photonic crystals cause active colour change in chameleons. Watch the videos…
According to Nature Communications, new research shows chameleons by stretching or relaxing its skin, actively tune nano-crystals to change their color.
“It is generally interpreted that these changes are due to dispersion/aggregation of pigment-containing organelles within dermal chromatophores.”
The 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).
In vivo colour change in a Furcifer pardalis (Panther Chameleon) adult male under excitation upon presentation of another adult male in its vision field. The original video is stabilised and accelerated 8 times. The first frame of the movie is shown in the lower-right for a better visualisation of the extend of colour change.
