One of four elderly persons falls every year in the United States. With more than 37 million hospitalizations every year, roughly one million falls occur in hospitals and can lead to serious injury and even death. Patients ...

Researchers turn light upside down

Researchers from CIC nanoGUNE (San Sebastian, Spain) and collaborators have reported in Science the development of a so-called hyperbolic metasurface on which light propagates with completely reshaped wafefronts. This scientific ...

Imaging technique unlocks the secrets of 17th century artists

The secrets of 17th century artists can now be revealed, thanks to 21st century signal processing. Using modern high-speed scanners and the advanced signal processing techniques, researchers at the Georgia Institute of Technology ...

More objective than human hearing

In industrial production, the testing of machines and products by means of acoustic signals still takes a niche role. At the Hannover Messe 2017, Fraunhofer is exhibiting a cognitive system that detects erroneous sounds more ...

A nano-roundabout for light

Just like in normal road traffic, crossings are indispensable in optical signal processing. In order to avoid collisions, a clear traffic rule is required. A new method has now been developed at TU Wien to provide such a ...
