(Phys.org) —Scientists have determined that an asteroid that burned up over Russia in February resulted in a shock wave so powerful that it traveled twice around the globe. They made that determination by means of a system ...
A team of mechanical engineers at the University of California San Diego has successfully used acoustic waves to move fluids through small channels at the nanoscale. The breakthrough is a first step toward the manufacturing ...

When a sound wave hits an obstacle and is scattered, the signal may be lost or degraded. But what if you could guide the signal around that obstacle, as if the interfering barrier didn't even exist? Recently, researchers ...
