A new imaging breakthrough combines ultrasound and light-based techniques to generate vivid 3D images that show both tissue ...

The range of materials that concrete contains scatters normal sound waves, making clear imaging difficult to obtain.

Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...

New broadband ultrasonic system creates high-resolution 3D images of hidden concrete defects without manual tuning.

NYU physics researchers have observed a new type of time crystal—one whose particles levitate on a cushion of sound while interacting with each other by exchanging sound waves. Above, a bead (purple) ...

Researchers developed a high-resolution 3D ultrasonic imaging system for concrete, adapting to various structures for effective nondestructive testing.

The range of materials that concrete contains, such as stone, chalk, and sand, scatters normal sound waves, making clear ...

Vertical graphene microstructures break the thickness-performance tradeoff in thermoacoustic speakers, enabling flexible ...

Elusive beaked whales off the Louisiana coast may sometimes be diving right to the seafloor, finds new 3D acoustic technology which accurately pinpoints their locations using their echolocation clicks ...

In A Nutshell MIT researchers built a portable ultrasound device weighing just over one pound that images more than 4 inches ...

Scientists have captured a rare view of one of the ocean's least understood whales—without ever seeing it. By listening to ...
