With a flick of a switch, current technologies allow you to quickly change materials from being dark to light, or cold to hot, just by blocking or transmitting specific wavelengths. But now, inspired by squid skin, researchers report a soft film that can regulate its transparency across a large range of wavelengths -- visible, infrared and microwave -- simultaneously. They demonstrated the material in smart windows and in health monitoring and temperature management applications.
