X-ray snapshot of butterfly wings reveals underlying physics of color

A team of physicists that visualized the internal nanostructure of an intact butterfly wing has discovered two physical attributes that make those structures so bright and colorful. “Over millions of years, butterflies have evolved sophisticated cellular mechanisms to grow brightly colored structures, normally for the purpose of camouflage as well ...

Tiny Tests Probe for Dark Matter and Other Exotic Physics

To answer some of the biggest unsolved questions in the cosmos, you might not need a supercollider. For decades, theorists have been dreaming up a Wild West of exotic physics that could be visible at scales just below the thickness of a dollar bill—provided you build a clever-enough experiment, one ...
