It’s hard to imagine a world without the lithium-ion batteries that power today’s laptops and mobile devices, but the technology does have its limits. One way scientists are working to break a ...

When high-voltage electricity breaks out in open air, it rips through the atmosphere, forming chaotic, branching fingers of electric plasma. These electrical arcs are difficult to control. They branch ...

Apple could use ultrasonic sound waves to deliver haptic feedback to wearers of its upcoming AR/VR headset when they interact with virtual objects. Most consumer AR/VR headsets do not provide haptic ...

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 ...

WYOMING, Mich. — People with liver cancer will now have a new treatment option, using ultrasound to disrupt tumors. University of Michigan Health West is the second hospital in the state to do it.

A new study provides the first visual evidence showing that brain circuits in living animals can be activated by ultrasound waves projected into specific patterns (holograms). Led by scientists at NYU ...
