In laboratories from Brazil to Munich, researchers are learning to grab matter with sound alone, sculpting ultrasonic waves into invisible “hands” that can lift, push, and rotate objects without a ...
Researchers in Tokyo have put a new twist on the use of sound to suspend objects in air. They've used ultrasonic standing waves to trap pieces of wood, metal, and water – and even move them around.
What does the future of construction look like? Autonomous machines buzzing around a building site? Giant 3D printers extruding walls and floors? Looking forward even farther, researchers at the ...
