When NASA’s Voyager 1 spacecraft sailed past Jupiter in 1979, it recorded a stunning and unusual phenomenon—plasma waves as ...

Sound waves are produced by movement. Animals have evolved organs to detect those sound waves in the air or water to perceive ...

Sound needs a medium (solid, liquid, or gas) to travel. Space is a vacuum, lacking the matter to carry sound waves. No sound in space means no echoes. While a near-perfect vacuum, some sounds can ...

“Sound waves, in particular, offer distinct advantages, as they are biocompatible and harmless and their short wavelengths can penetrate a wide range of heterogeneous, opaque and absorbing media ...

Gaining insight from sound! Dan Smith shows how one man's metal plates have helped us understand acoustics for a few ...

The process used to direct the sound waves not only guides the waves in one direction but the researchers say it also amplifies them. From ETH Zurich: “Schematics of the experimental set-up ...

For the first time, researchers were able to transmit, or "tunnel," sound waves across extremely small distances between two crystals in a vacuum. When you purchase through links on our site, we ...

The sound waves are typically generated in a particular range (determined by the properties of the material). This lets you play a trick. Instead of one light beam, you send in two.

“We can use the sound waves to apply just the right amount of pressure in the right places to the stem cells, to trigger the change process,” said Leslie Yeo, co-lead researcher on the study.
