We are surrounded by waves. tiny vibrational waves transport sound to our ears. Light waves stimulate the retinas of our eyes. Electromagnetic waves bring radio, television and endless streaming ...

Acoustics is the branch of science that studies the propagation of sound and vibrational waves. Audible acoustic waves are ubiquitous in our everyday experience: they form the basis of verbal human ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

It’s a question I’m sure was keeping you up at night: can you make an object spin with a sound wave? The answer, generally speaking, used to be no. Now, though, mechanical engineers have taken a look ...

You ever get the feeling sounds are controlling your mind? Maybe a catchy song gets stuck in your head. Or a noisy neighbor won't stop driving you nuts. Well, sounds may not literally control your ...

Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves ...

Forget fad diets and sketchy supplements, your favorite song might be the key to staying thin. In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave — ...

Look at that mountain! Imagine you are standing at the base of a volcano looking up. You were told that the volcano isn’t going to erupt anytime soon, but you notice a little bit of smoke (or is that ...

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...
