On the rise. Signs of convection are seen in the motion of hot gas under the influence of a gravity-like acoustic force in a spherical glass container. The images were recorded 15, 40, and 140 ...

Although movie and game producers can now create computer-animated images of just about anything, the sounds made by those onscreen items still typically consist of recordings of real-world objects.

The area of sound is fascinating researchers and after a recent study of bendable sound waves that could result in localised reception, they have now delved into how sound can be used in weight loss.

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...
