MIT researchers observe a “second wave” of heat in superfluid helium, confirming that heat propagates like sound.

The rapper known as Rod Wave faces more than a dozen charges, some involving a gun, after he turned himself in to sheriff’s ...

In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a ...

Save guides, add subjects and pick up where you left off with your BBC account. A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a ...

By contrast, “The History of Sound,” which might be described as a minimalist “Masterpiece Theatre”-on-the-frontier riff on “Brokeback,” is a drama that mostly just sits there.

Operating with glass microfibres that conduct sound waves, data processing is more efficient thanks to use of different frequencies. They have transformed normal fabrics into smart sensors that react ...

Sound doesn’t just help us hear music or communicate underwater—it can also be used to move objects without physically ...

A newly developed metamaterial enables sound waves to manipulate objects underwater without any need for physical contact.

Sound waves do far more than carry music or voices. In science and engineering, they help map the seafloor, monitor earthquakes, guide submarines, and even shatter kidney stones inside the human body.
