Researchers at the University of Washington have demonstrated how it is possible to transform a smart device into a surveillance tool that can collect information about the body position and movements of the user, as well as other people in the device's immediate vicinity.
Electricity distribution systems in the USA are gradually being modernized and transposed to smart grids, which make use of two-way communication and computer processing. This is making them increasingly vulnerable to cyber attacks. In a recent paper in Elsevier's International Journal of Critical Infrastructure Protection, Dr. Sujeet Shenoi and his colleagues from the Tandy School of Computer Science, University of Tulsa, US, have analyzed these security issues.
Researchers have demonstrated the transmission of two separate video signals through a terahertz multiplexer at a data rate more than 100 times faster than today's fastest cellular data networks.
A research collaboration between the University of Illinois at Urbana-Champaign, the National Institute of Standards and Technology, and the University of Maryland has revealed a new technique by which scattering of sound waves from disorder in a material can be suppressed on demand. All of this, can be simply achieved by illuminating with the appropriate color of laser light.
A mobile learning app that uses game elements such as leaderboards and digital badges may have positive effects on student academic performance, engagement, and retention, according to a study published in the open access International Journal of Educational Technology in Higher Education. Researchers at Swinburne University of Technology, Australia developed a fully customizable app that allowed lecturers to push quizzes based on course content directly to their students' devices in order to motivate them, increase their competitiveness, and keep them engaged with the course.
Physicists from the ARC Centre of Excellence for Ultrahigh bandwidth Devices for Optical Systems (CUDOS) developed a new hybrid integrated platform, promising to be a more advanced alternative to conventional integrated circuits. The researchers demonstrated their approach is mass manufacturable, making it possible to integrate the platform into everyday electronic equipment like smartphones. For end users this technical advance means it may lead to faster internet on their next-generation electronic devices.
Brown University researchers have developed a new kind of polarizing beamsplitter for terahertz radiation, which could prove useful in imaging and communications systems.
University of Washington researchers have developed a fast, inexpensive method to make electrodes for supercapacitors, with applications in electric cars, wireless telecommunications and high-powered lasers.
These innovations were published in the July/August 2017 issue of Annals of Family Medicine. Links go live at 5 p.m. ET, July 10.
The National Institute of Information and Communications Technology (NICT) developed the world's smallest and lightest quantum-communication transmitter (SOTA) onboard the microsatellite SOCRATES. We succeeded in the demonstration of the first quantum- communication experiment from space, receiving information from the satellite in a single-photon regime in an optical ground station in Koganei city. This is a major step toward building a global long-haul and truly-secure satellite communication network.
