A research team at Carnegie Mellon University has developed a new noninvasive brain stimulation technique, by showing how focused ultrasound affects the human brain. Using brainwave recordings from ...

When hit with low-frequency ultrasound, the nanoparticles release antibiotics deep inside bacterial communities ...

Engineers at Duke University have demonstrated a technique that uses microbubbles and ultrasound to help relatively large ...

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 ...

Scientists discover hedgehogs hear ultrasound, opening the possibility of warning sounds that keep them away from roads.

Road traffic accidents kill up to one in three hedgehogs in local populations. It’s not easy to deter hedgehogs from venturing on dangerous roads, but their hearing could be surprisingly useful. In a ...

A sound too high for you to hear may one day help keep hedgehogs off the road. That possibility comes from a new study in Biology Letters reporting that European hedgehogs can hear ultrasound, with ...

Doctors have a new emerging weapon in the fight against cancerous tumors: ultrasound. After a five-year study by the ...

When you hear "brain-computer interface," you probably picture surgery, wires and a chip in your head. Now picture something quieter. No implant. No incision. Just sound waves directed at the brain.

When particles in volcanic ash cloud rub together, some pick up positive charge and others negative – now physicists have ...

Have you been part of the shift? Many IT teams are now more influential—and necessary—in the assessment, purchase decision and implementation of healthcare software. From technological advancements ...
