According to the United Nations' telecommunications agency, 93% of the global population has access to a mobile-broadband network of some kind. With data becoming more readily available to consumers, there is also an appetite for more of it, and at faster speeds.
A peer-reviewed study by the Environmental Working Group recommends stringent health-based exposure standards for both children and adults for radiofrequency radiation emitted from wireless devices. EWG's children's guideline is the first of its kind and fills a gap left by federal regulators.
Creating new procedures that improve mass drone traffic is the purpose of LABYRINTH, a European research project coordinated by the Universidad Carlos III de Madrid (UC3M) with the participation of 13 international organisations within the R&D&I, transport, emergency, and auxiliary services fields. Researchers hope to use these drone swarm applications to improve civil road, train, sea, and air transport, making it safer, more efficient, and more sustainable.
What The Study Did: The association between primary care payment models and the use of telemedicine for Medicare Advantage enrollees during the COVID-19 pandemic was examined in this study.
A collaborative team from the Terasaki Institute for Biomedical Innovation has designed a wearable strain sensing device that can effectively detect a wide range of strains.
Researchers from the National Institute of Information and Communications Technology (NICT), Network Research Institute, succeeded the first S, C and L-bands transmission over long-haul distances in a 4-core optical fiber with standard outer diameter (0.125 mm). The researchers constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km.
What The Study Did: Researchers characterized clinical content of ambulatory care among office-based compared with telemedicine visits in the United States before and during the COVID-19 pandemic.
Screens may be larger on smartphones now, but nearly every other component is designed to be thinner, flatter and tinier than ever before. The engineering requires a shift from shapely, and bulky lenses to the development of miniaturized, two-dimensional metalenses. They might look better, but do they work better? A team of Japan-based researchers says yes, thanks to a solution they published on July 7th in Applied Physics Express, a journal of the Japan Society of Applied Physics.
The twin technologies of unmanned aerial vehicles and wireless sensors could be the ideal combination to counter forest fires.
Photonics researchers demonstrate 11-fold compression of light in time, introducing an important paradigm for light generation in advanced metrology, imaging and high speed optical communications.
