Negative pressure is a rare and challenging-to-detect phenomenon in physics. Using liquid-filled optical fibers and sound waves, researchers have now discovered a new method to measure it. In ...

NASA has released a chilling audio clip that lets human ears experience the sound of a supermassive black hole, at least in a ...

NASA created a haunting audio clip of sound waves rippling out of a supermassive black hole, located 250 million light-years away.

For a wide variety of emerging quantum technologies, such as secure quantum communications and quantum computing, quantum entanglement is a prerequisite. Scientists have now demonstrated a ...

In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...

A long-term study found that daily 40Hz light and sound stimulation may help slow cognitive decline in people with late-onset ...

For decades, scientists have worked to peer deeper into the brain. They have wanted to see not just surface activity in the cortex but also the hidden layers beneath, such as the hippocampus, where ...
