From the articles:

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 Public University of Navarre in Spain have been experimenting with using sound waves to make building materials simply float into position without any physical interaction required.
