Researchers have succeeded in directing floating objects around an aquatic obstacle course using only soundwaves. Their novel, optics-inspired method holds great promise for biomedical applications ...
A tiny polystyrene bead hangs in midair, nearly 40 centimeters above a square array of ultrasonic emitters. No wire holds it. There are no magnets; not that it would matter since the object is made of ...
Physically, sound is just pressure moving through a medium. If you harness that pressure correctly, you can actually push things around using nothing but sound. That's exactly what researchers at ...
