The neural structure we use to store and process information in verbal working memory is more complex than previously understood, finds a new study by New York University researchers. It shows that processing information in working memory involves 2 different networks in the brain rather than one—a discovery that has implications for the creation of artificial intelligence (AI) systems, such as speech translation tools.

“Our results show there are at least two brain networks th...

Combining silicon with a light-producing semiconductor may help develop micrometer-scale lasers, shows Doris Keh-Ting Ng and her colleagues from A*STAR Data Storage Institute. Silicon has revolutionized the manufacture of electrical devices. Electronic engineers would like to further expand the functionality of these integrated circuits by enabling them to create, manipulate and detect light. These optoelectronic devices could speed up processing of digital information, and lead to micrometer-scale lasers, for use in barcode scanners for example.

The problem, however, is that silicon is not an efficient lig...

The structure of super-flexible LC device is created by ultra-thin plastic substrates bonded by polymer wall spacers.

Researchers at Tohoku University have developed a super flexible liquid crystal (LC) device, in which 2 ultra-thin plastic substrates are firmly bonded by polymer wall spacers. The team, led by Professor Hideo Fujikake and Associate Professor Takahiro Ishinabe of the School of Engineering, hopes the new organic materials will help make electronic displays and devices more flexible, increasing their portability and all round versatility. New usage concepts with flexibility and high quality display could offer endless possibilities in near-future information services.

Previous attempts to create a flexible display using an organic light-emitting diode (OLED) device with a th...

The day of charging cellphones with finger swipes and powering Bluetooth headsets simply by walking is now much closer. Michigan State University engineering researchers have created a new way to harvest energy from human motion, using a film-like device that actually can be folded to create more power...
