How Nanoscale Optics Create Nature's Most Dazzling Colors

What do a butterfly's shimmering wings, a fish's opalescent scales, and a peacock's brilliant feathers have in common? Yes, their colors are beautifully iridescent. But they are also produced by the physical interaction of light with sophisticated nanoscale architecture that we are only just beginning to understand. » 2/19/15 2:00pm 2/19/15 2:00pm

How do paleontologists determine what color a dinosaur's feathers were?

Last week, researchers studying a dinosaur named Microraptor published the results of a remarkable discovery: this small, four-winged dinosaur was covered from head-to-toe in black feathers, but shone with a glossy hint of blue. In other words, its plumage was iridescent. » 3/14/12 11:10am 3/14/12 11:10am
