A team of Caltech researchers is proposing a radical new technique for killing cancer cells using low-intensity ultrasound waves. The preliminary research is still at an incredibly early stage but ...

Researchers have demonstrated a technique for detecting and controlling ultrahigh frequency sound waves at the nanometer scale. This represents an advance towards next generation ultrasonic imaging ...

The future is wireless power, or so say a thousand press releases in my spam folder, and with very few exceptions every single system of wireless power delivery has fallen flat on its face. Except for ...

It’s well known that many animals are particularly sensitive to high-frequency sounds that humans can’t hear. Many commercial pest repellers based on this principle are available, most of them ...
