(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 ...
Researchers at the U.S. Naval Research Laboratory (NRL), Optical Sciences Division, in collaboration with the laboratory's Material Science Division, for the first time have demonstrated successful detection of acoustic emission ...

When placed in an acoustic field, small objects experience a net force that can be used to levitate the objects in air. In a new study, researchers have experimentally demonstrated the acoustic levitation of a 50-mm (2-inch) ...
EPFL scientists have invented a new type of "acoustic prism" that can split a sound into its constituent frequencies. Their acoustic prism has applications in sound detection.
