Soil tested for hidden contaminants in community gardens

This year saw many people rediscovering an interest in gardening, digging in the dirt and maybe even harvesting vegetables from a garden plot. But around the Puget Sound, not all garden soils are created equal. Soil, particularly ...

Spin-sonics: Acoustic wave gets the electrons spinning

Researchers have detected the rolling movement of a nano-acoustic wave predicted by the famous physicist and Nobel prize winner Lord Rayleigh in 1885. This phenomenon can find applications in acoustic quantum technologies ...

Acoustic tweezers can pick up objects without physical contact

Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate ...

Artificial intelligence helps improve NASA's eyes on the Sun

A group of researchers is using artificial intelligence techniques to calibrate some of NASA's images of the Sun, helping improve the data that scientists use for solar research. The new technique was published in the journal ...

To track elephants, scientists keep an ear to the ground

The "mini earthquakes" that elephants make by both walking and vocalizing are not only a way to communicate with each other but can be used to track their movements, according to a study published Wednesday.

Collecting more than just seismic data along the Cascadia Fault

Down in the main lab of the R/V Marcus Langseth, you'll find an array of monitors—46, to be exact!—all displaying information about the data we're collecting. While many of the screens are dedicated to monitoring the ...

Thermal waves observed in semiconductor materials

A study published in Science Advances reports on the unexpected observation of thermal waves in germanium, a semiconductor material, for the first time. This phenomenon may allow a significant improvement in the performance ...

Sound

Sound is a travelling wave which is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations.
