Breakthrough in nonlinear optics research

A method to selectively enhance or inhibit optical nonlinearities in a chip-scale device has been developed by scientists, led by the University of Sydney. The researchers from the Centre for Ultrahigh bandwidth Devices for ...

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 University and ...

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.

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 cell spacing ...
