Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...

Radically new and powerful things are being done with sound. Part of what I think is the growing trend of greater control of all information, light, energy, matter and magnetism. (ILEMM) Molecular ...

Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have discovered a way to control ...

Although few people ever get the chance to travel at the speed of sound, it is an alluring flight goal and an impressive technological feat. Though average people have flown at high speeds on ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

For the first time, physicists have discovered a way to levitate large objects—as in, human-sized objects—with an acoustic tractor beam. Researchers from the University of Bristol became the first to ...

Upper limit: a US Navy F/A-18 travelling near the speed of sound in air. The white halo comprises water droplets that have condensed from the air because of the sudden drop in pressure behind the ...

Researchers are developing innovative honeycomb structures that could make possible a new approach to noise reduction in aircraft. Composed of many tiny tubes, the structures can reduce sound more ...

King, who is Oscar-nominated for his work on the historical epic, on how his work ranged from large- to small-scale moments. By Beatrice Verhoeven Deputy Awards Editor For sound editor Richard King, ...

Researchers carefully studied bubbles that form when water droplets come into contact with heated cooking oil and found that the type and number of bubbles formed depends on the amount of water ...

Noise from commercial and military jet aircraft causes environmental problems for communities near airports, obliging airplanes to follow often complex noise-abatement procedures on takeoff and ...
