As an airplane flies faster than the speed of sound, it "pushes" on the sound waves in front of it. But sound waves obey the speed limit—they can't travel faster than the speed of sound. So the waves ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. We live our entire lives surrounded by them. They slam into us ...

Sound needs a medium (solid, liquid, or gas) to travel. Space is a vacuum, lacking the matter to carry sound waves. No sound in space means no echoes. While a near-perfect vacuum, some sounds can be ...

A research team has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered ...

Forget fad diets and sketchy supplements, your favorite song might be the key to staying thin. In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave — ...
