New study identifies key design features that boost violins' acoustic power
Some of the most prized violins in the world were crafted in the Italian workshops of Amati, Stradivari, and Guarneri—master violinmaking families from the 17th and 18th centuries who produced increasingly ...
Acoustic tweezers device expands the range of X-ray crystallography
A device for precisely positioning small objects using acoustic waves has now been used to position fragile protein crystals a few micrometers or less in size in the path of a crystallography X-ray beam. ...
Study examines role of acoustic-gravity waves as ocean transport, early warning of tsunamis
Acoustic-gravity waves—a special type of sound wave that can cut through the deep ocean at the speed of sound—can be generated by underwater earthquakes, explosions, and landslides, as well as by surface ...
The sound of chirping birds in the control center
When the alarm light starts blinking in the control room of a factory, the problem has already occurred. Computer scientists at the Cluster of Excellence Cognitive Interactive Technology (CITEC) at Bielefeld ...
Acoustic levitation made simple
A team of researchers at the University of São Paulo in Brazil has developed a new levitation device that can hover a tiny object with more control than any instrument that has come before.
Scientists sweep cells apart for use in medical research
Scientists have developed a new method to separate cells, which could lead to more efficient medical research.
Acoustic tweezers manipulate cell-to-cell contact
Sound waves can precisely position groups of cells for study without the danger of changing or damaging the cells, according to a team of Penn State researchers who are using surface acoustic waves to manipulate ...
Syracuse biologist reveals how whales may 'sing' for their supper
Humpback whales have a trick or two, when it comes to finding a quick snack at the bottom of the ocean. But how they pinpoint that meal at night, with little or no available light, remains a mystery.
Researchers listen in on 'conversations' between calves and their mothers
Researchers have been eavesdropping on 'conversations' between calves and their mothers—measuring the process of how cows communicate using detailed acoustic analysis for the first time.
