"We showed that we could measure how the plastron changes and gradually dissolves into the water, by monitoring the variation of wave speed over time. This system could be used as a sensor in other ...

New research has unraveled the mystery of how microscopic cilia coordinate to move and propel marine creatures through water.

Throughout most of Earth, seismic waves speed up as they travel deeper. A notable exception is the boundary between the rocky mantle and the liquid outer core, at a depth of about 2,900 kilometres. A ...

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 ...

Ripples, like ones produced by raindrops falling in a puddle, are also called capillary waves. Studied since antiquity, they have garnered considerable interest in modern science due to their ability ...
