Computers that perceive human emotion As part of the growing field of “affective computing,” MIT researchers have developed a machine-learning model that takes computers a step closer to interpreting our emotions as naturally as humans do. Affective computing uses robots and computers to analyze facial expressions, interpret emotions, and respond accordingly. Applications include, for ... » read more

Single-atom storage Scientists at EPFL are working on a single-atom magnetic data storage device that takes advantage of quantum effects to provide dense storage. The team is using holmium, an element they've been exploring for years. "Single-atom magnets offer an interesting perspective because quantum mechanics may offer shortcuts across their stability barriers that we could exploit in t... » read more

Tandem solar reaches 25.2% efficiency In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power. Recently, two groups have reache... » read more

Compressing data in vehicles As the number of cameras in automobiles is on the rise with the move to autonomous vehicles, internal vehicle networks are being pushed to their limits from the flood of data. While special compression methods reduce the amount of video data, they also exhibit a high degree of latency for coding. But now, Fraunhofer researchers have adapted video compression in su... » read more

Eel-inspired power Researchers at the University of Michigan, the University of Fribourg, and the University of California-San Diego developed soft power cells with the potential to power implanted medical devices. Made of hydrogel and salt, the soft cells form the first potentially biocompatible artificial electric organ that generates more than 100 volts at a low current, the team says, enou... » read more

Robots imagine their future to learn By playing with objects and then imagining how to get the task done, UC Berkeley researchers have developed a robotic learning technology that enables robots to figure out how to manipulate objects they have never encountered before. The team expects this technology could help self-driving cars anticipate future events on the road and produce more intel... » read more

Stabilizing perovskites Scientists at EPFL and the University of Cordoba found a way to improve the stability of perovskite solar cells. While perovskites show promising efficiencies as solar cells, they are soft crystalline materials and prone to problems due to decomposition over time. By introducing the large organic cation guanidinium (CH6N3+) into methylammonium lead iodide perovskites, t... » read more

3D diodes At the recent IEEE International Electron Devices Meeting (IEDM) in San Francisco, the Ecole Polytechnique Fédérale de Lausanne (EPFL) and Taiwan Semiconductor Manufacturing Co. Ltd. (TSMC) presented a paper on what they call the world’s first back-illuminated 3D-stacked, single-photon avalanche diode (SPAD) in 45nm CMOS technology. A SPAD is one type of a photodetector. These... » read more

Redefining unit measurements At a recent meeting, the International Committee for Weights and Measures (CIPM) took the next step towards the expected redefinition of four base units within the International System of Units (SI). The SI base units include the following metrics or constants--meter, kilogram, second, ampere, kelvin, mole, and the candela. Here’s the fundamental constant... » read more
