Sound-proof metamaterial inspired by spider webs

(Phys.org)—Spider silk is well-known for its unusual combination of being both lightweight and extremely strong—in some cases, stronger than steel. Due to these properties, researchers have been developing spider-silk-inspired ...

Engineers discover a new gatekeeper for light

Imagine a device that is selectively transparent to various wavelengths of light at one moment, and opaque to them the next, following a minute adjustment.
