Chameleons change color via a layer of skin cells 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.

When a patient is suffering from a condition such as venous leg ulcers, that limb needs to be wrapped in a compression bandage. It's important, however, that the the correct amount of pressure is applied. New color-changing bandage fibers have been designed to ensure that caregivers get it right.
