Ultra thin bright-light emitting device pave way for ‘invisible’ displays

Researchers at UC Berkeley have developed what they claim is just millimeters wide bright-light emitting device capable of paving way for ‘invisible’ displays. These emitting devices become fully transparent when turned off. The light emitting material in this device is a monolayer semiconductor, which is just three atoms thick. The device opens the door to invisible displays on walls and windows – displays that would be bright when turned on but see-through when turned off — or in futuristic applications such as light-emitting tattoos, according to the researchers. The device was developed in the laboratory of Ali Javey, professor of Electrical Engineering and Computer …

Device can detect severe stroke in seconds with 92% accuracy

Researchers have developed a new portable device that is that is capable of detecting severe stroke in a matter of few seconds with 92 per cent accuracy. Researchers at the Medical University of South Carolina (MUSC), Mount Sinai, the University of Tennessee Health Sciences Center and colleagues from other institutions have published their findings in the Journal of Neurointerventional Surgery. The volumetric impedance phase shift spectroscopy (VIPS) device (Cerebrotech VisorTM, Cerebrotech Medical Systems, Pleasanton, CA) works by sending low-energy radio waves through the brain that change frequency when passing through fluids. Such waves are reflected back through the brain and …

WhatsApp, PokémonGo and Tinder being used by people in Finland while driving

Use of smartphones while driving is seen by many countries as an offence owing to the issues that may arise due to inattentive driving including death. Despite this people around the world continue using their phones while driving for activities. While these activities may range from placing a call to playing games, there is little information on what motorists actually do with their smartphones while driving. Researchers at the University of Jyväskylä tracked how Finnish drivers use their smartphones while driving. Drivers seem to use the same applications in traffic as elsewhere, without much moderation. Unexpectedly, heavy smartphone users even …

Information security can be improved by giving users more options: study

Researchers have suggested that businesses can improve their information security by giving their employees – users – more options. According to a recently published study in the Journal of Management Information Systems, security managers and supervisors could have greater success in motivating employees to act more securely by avoiding cold, authoritative commands, and instead create security messages that are relatable and provide options for how employees can better protect information and respond to threats. The study by researchers at Washington State University and colleagues employees may fail to realize they are putting company data at risk or have less of …
