Reducing noise transmitted through an open window

A new device that can reduce the intensity of sound passing through open windows is presented in a proof-of-principle study in Scientific Reports. It fits into a two-panel sliding window and can decrease the perceived loudness ...

Computational model decodes speech by predicting it

The brain analyzes spoken language by recognizing syllables. Scientists from the University of Geneva (UNIGE) and the Evolving Language National Centre for Competence in Research (NCCR) have designed a computational model ...

Artificial brains may need sleep too

No one can say whether androids will dream of electric sheep, but they will almost certainly need periods of rest that offer benefits similar to those that sleep provides to living brains, according to new research from Los ...

A system for the nonreciprocal transmission of microwave acoustic waves

Acoustic waves have been found to be highly versatile and promising carriers of information between chip-based electronic devices. This characteristic is ideal for the development of a number of electronic components, including ...

High-security identification that cannot be counterfeited

Try whispering at one end of the Echo Wall in the Temple of Heaven in Beijing. People at the far end of the curved wall will hear you from 65 meters away. This is the whispering-gallery effect. Now, researchers from Japan ...

'One-way' electronic devices enter the mainstream

Waves, whether they are light waves, sound waves, or any other kind, travel in the same manner in forward and reverse directions—this is known as the principle of reciprocity. If we could route waves in one direction only—breaking ...
