Researchers have created a silicon carbide (SiC) photonic integrated chip that can be thermally tuned by applying an electric signal. The approach could one day be used to create a large range of reconfigurable devices such as phase-shifters and tunable optical couplers needed for networking applications and quantum information processing.
Read moreIn recent years, the seemingly inevitable 'internet of things' has attracted considerable attention: the idea that in the future, everything in the physical world — machines, objects, people — will be connected to the internet. Drawing on lessons learned from studies on a variety of marine animals outfitted with sensors, researchers in a new perspective article describe how an 'internet of health' could revolutionize human medicine.
Read moreScientists have developed new technology, dubbed 'Knocker', which identifies objects and executes actions just by knocking on them with the smartphone. Software powered by machine learning of sounds, vibrations, and other reactions will follow the users' directions.
Read moreThe cryptocurrency Bitcoin is limited by its astronomical electricity consumption and outsized carbon footprint. A nearly zero-energy alternative sounds too good to be true, but as a professor explains, it all comes down to our understanding of what makes transactions secure.
Read moreA new way to achieve integrated photonics — a new device has been developed that could have applications in imaging, sensing and quantum information processing, such as on-chip transformation optics, mathematical operations and spectrometers.
Read moreA group of researchers developed a highly sensitive rectifying element in the form of a nanowire backward diode, which can covert low-power microwaves into electricity. The new technology is expected that the newly-developed nanowire backward diode will be applied in using plentiful ambient radio wave energy in 5G communications, serving as a stable power source of sensors and contributing to battery-free sensors.
Read moreIn a new study, researchers find that there is, in fact, a way for Indian cities to preserve citizen privacy while using their data to improve efficiency.
Read moreThe research community is increasingly recognizing video as more than just a medium to disseminate scientific findings after a study's conclusion. A powerful tool, film can engage study participants and become an integral part of the scientific process, when deployed thoughtfully. To guide this emerging practice, University of Pittsburgh Graduate School of Public Health scientists performed the first review of studies on use of film in public health research.
Read moreArtificial intelligence (AI) appears to detect diseases from medical imaging with similar levels of accuracy as health-care professionals, according to the first systematic review and meta-analysis, synthesizing the available evidence from the scientific literature.
Read more'Keep your eyes on the road.' With the recent advances in vehicle-assisted safety technology and in-car displays, this old adage has a new meaning, thanks to two new applications of eye-tracking technology.
