In context: Sound waves typically propagate in forward and backward directions. This natural movement is problematic in some situations where unwanted reflections cause interference or reduced ...

In physics, a mechanical kink marks the point of transition between different internal states of a material. Researchers have now succeeded in creating a model in which they were able to move the kink ...

The takeaway: New research is challenging a basic assumption about espresso: that it has to be made with hot water. Instead of relying on near-boiling water, researchers have shown that high-frequency ...

An international team of scientists has developed a new analysis of how sound waves behave, revealing surprising effects that have largely been overlooked for decades. In the new paper in Scientific ...

Researchers have pioneered the use of parallel computing on graphics cards to simulate acoustic turbulence. This type of simulation, which previously required a supercomputer, can now be performed on ...
