Spider-web 'labyrinths' may help reduce noise pollution

(Phys.org)—Researchers have demonstrated that the geometry of a natural spider web can be used to design new structures that address one of the biggest challenges in sound control: reducing low-frequency noise, which is ...

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.

New ultrasound techniques for peering inside bony structures

Ultrasound—sound with frequencies higher than those audible to humans—is commonly used in diagnostic imaging of the body's soft tissues, including muscles, joints, tendons and internal organs. A technology called high-intensity ...

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.

Acoustic emissions from organic martensite analogues

Some organic crystals jump around when heated up. This happens because of an extremely fast change in their crystal structure. In the journal Angewandte Chemie, scientists have now demonstrated that the crystals send out ...
