By harnessing electron-beam patterning to control the swelling and contraction of a soft polymer, researchers created a material that can change both color and texture on demand.

Stanford researchers have developed a flexible material that can quickly change its surface texture and colors, offering potential applications in camouflage, art, robotics, and even nanoscale ...

To control color, the team sandwiched the polymer between two gold films. Light bounces off these films and interferes in ways that create various colors. When the polymer swells to varying extents in ...

Heliconius charithonia is one of the species of butterflies whose wing patterns scientists scrutinized to better understand the evolutionary process. This butterfly is wild-type; the genetically ...

With fanciful flight and their tapestry of colorful patterns and hues, butterflies bring enchantment to the garden with an ever-changing spectacle of movement and color. But there's more to these ...
