YALE (US)—Most colors in nature—from the color of our skin to the green of trees—are produced by pigments. But the bright blue feathers found in many birds, such as Bluebirds and Blue Jays, are instead produced by nanostructures. Under an electron microscope, these tiny structures—similar to beer foam—look like sponges. Continue…
