Haifa, Israel June 11, 2021 - Using an ultrafast transmission electron microscope, researchers from the Technion - Israel Institute of Technology have, for the first time, recorded the propagation of ...

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 ...

Sound waves traveling thousands of kilometers through the ocean may help scientists monitor climate change. As greenhouse gas emissions warm the planet, the ocean is absorbing vast amounts of that ...

NASA has released a chilling audio clip that lets human ears experience the sound of a supermassive black hole, at least in a heavily modified form. The recording, generated from data captured in 2003 ...

Acoustics is a missing dimension in silicon chips because acoustics can complete specific tasks that are difficult to do with electronics and optics alone. For the first time researchers have added ...
