Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...

Ultrasonic sound waves have been used to levitate objects in crowded rooms to make hologram-like displays. Such acoustic levitation was previously only practical in empty spaces, but a new algorithm ...

Sound and object motion can be used to change perceptions about body size, according to a new study by an international team involving UCL researchers. The study, published today in PLOS ONE, found ...
