Many of the robotic systems developed in the past decades are inspired by four-legged (i.e., quadruped) animals, such as dogs ...

Yijie is an optical engineer, and the recent study was inspired by his research on light patterns. He and his colleagues had previously shown that light waves could move tiny particles within ...

But what if you could bend water waves to your will to move floating objects? Scientists have now developed a technique to merge waves in a water tank to produce complex patterns, such as twisting ...
