A team of researchers from the University of Stuttgart and the Julius-Maximilians-Universität Würzburg led by Prof. Stefanie Barz (University of Stuttgart) has demonstrated a source of single photons ...

LRAD sound weapons at protests use focused acoustic beams up to 162 decibels that cause permanent hearing damage, but ...

Astronomers have spotted runaway black holes screaming through space, leaving trails of stars in in their wake.

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 ...

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

Researchers at AppliedPhysics.org report early evidence that cells respond selectively to mathematically structured sound, not just acoustic power.

A new sensor detects helium leaks by monitoring how sound waves propagate through a topological material – no chemical ...

Like stretch marks left on skin that expanded too quickly or cracks embedded in freezing ice, cosmic strings are artifacts of ...

We like to think that the universe follows a strict set of logical rules, but every now and then, we stumble upon facts that ...

Electrons are usually described as particles, but in a rare quantum material, that picture completely breaks down ...

When [Electron Impressions] used a powerful ultrasonic array to project a narrow beam of sound toward a target, he described ...

So if we’re right, each former human is now essentially a radio transmitter and receiver. One plurb sends out a signal that ...
