Data on stolen mobile can be destroyed remotely

Data on stolen mobile can be destroyed remotely

Scientists have developed a tiny embedded system that could remotely destroy the memory of stolen or hacked electronic devices such as mobile phones, laptops and pen drives to prevent data theft1. “This system could be integrated with state-of-the-art high-performance silicon chips, making it potentially useful for protecting data in various fields such as intelligence, nationalRead more about Data on stolen mobile can be destroyed remotely[…]

A chemical trick that makes metal atoms emit light

A chemical trick that makes metal atoms emit light

Nanoclusters of metal atoms are promising for their fluorescence, low toxicity and stability under light. However, the underlying causes of these features have not been adequately scrutinized, something that a new research from Saudi Arabia and China is trying to change by studying the metal atoms under different light and heat conditions to fine-tune theirRead more about A chemical trick that makes metal atoms emit light[…]

Smarter routers and processors for better communication systems

Smarter routers and processors for better communication systems

A team of physicists has developed a new way to control the paths of light beams trapped in liquid crystals using laser beams and external magnetic fields1. This magneto-optical control will aid in developing efficient and robust signal processing methods for optical communication systems. “Our method can replace some important elements in the optical communicationRead more about Smarter routers and processors for better communication systems[…]

Flexible sensors to track vital signs of the human body

Flexible sensors to track vital signs of the human body

Vertically stacked three-dimensional sensors exhibit low resistance, and consume less power and space1. The sensors are implantable and potentially useful for monitoring activities of brain cells, heart rates and body temperature. Current techniques stack sensors horizontally with a lot of wiring. Besides taking up space, they generate noise that attenuates desired signals. Researchers from KingRead more about Flexible sensors to track vital signs of the human body[…]
