Nanolaser changes color, just like a chameleon

Chameleons are able to change color via a layer of skin cells known as iridophores, which contain nanocrystals. As the lizards stretch or relax their skin, the spacing between those crystals changes, altering the manner in which they reflect light. Now, scientists have designed a color-changing nanolaser that works the same way...
