Nobody ever said anything about singing, though. A NASA spacecraft has just beamed back a beautiful song sung by our own planet.

Now you can levitate liquids and insects at home

Levitation techniques are no longer confined to the laboratory thanks to University of Bristol engineers who have developed an easier way for suspending matter in mid-air by developing a 3D-printed acoustic levitator.

Sound waves direct particles to self-assemble, self-heal

An elegantly simple experiment with floating particles self-assembling in response to sound waves has provided a new framework for studying how seemingly lifelike behaviors emerge in response to external forces.

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 ...

Tiny Music Player Made from Wire Bridge (w/ Video)

(PhysOrg.com) -- In 2008, scientists built a loudspeaker made of carbon nanotubes that produced sound and music based on the thermoacoustic effect. Now, a different team of scientists has built a loudspeaker made of tiny ...

Acoustic levitation could be used on Mars

(PhysOrg.com) -- The presence of fine dust on the Moon and Mars may present problems for explorers, such as coating solar panels, penetrating seals and interfering with machinery. Human explorers would also be endangered ...
