The changing color of a chameleon's body is an impressive sight—but how it happens has long been a significant scientific question without a compelling answer. Now, researchers have identified a thin layer of deformable nanocyrstals in their skin which gives rise to the phenomenon.
This surreal, beautiful short movie looks like gooey light effects at a dance party, but it actually demonstrates how nanocrystals work. The brilliant colors in you see in the liquid are actually millions of tiny crystals emitting light.
This awesome piece of nano-art shows dislocations in an arrangement of nano-crystals, each one 300 times smaller than a human hair. But it looks like the micro-universe is about to break into our own.
