New biosensor could monitor glucose levels in tears and sweat

Constantly tracking a person’s glucose levels through their tears or sweat could be one step closer to providing people with diabetes an improved monitoring tool. Researchers report in the journal ACS Nano the development of an ultra-thin, flexible sensor that could be incorporated into contact lenses or on the backs of watches for real-time glucose tracking.

Virtual reality goes magnetic

International research team develops electronic “skin.” The recent success of Pokémon GO made many people very familiar with the concept of “augmented reality”: computer-generated perception blends into the real and virtual worlds. So far, these apps have largely used optical methods for motion detection.

Himawari-8 data assimilated simulation enables 10-minute updates of rain and flood predictions

Using the power of Japan’s K computer, scientists from the RIKEN Advanced Institute for Computational Science and collaborators have shown that incorporating satellite data at frequent intervals—ten minutes in the case of this study—into weather prediction models can significantly improve the rainfall predictions of the models and allow more precise predictions of the rapid development of a typhoon.

Machine Learning Will Change Jobs

Machine learning computer systems, which get better with experience, are poised to transform the economy much as steam engines and electricity have in the past. They can outperform people in a number of tasks, though they are unlikely to replace people in all jobs.

Device makes power conversion more efficient

New design could dramatically cut energy waste in electric vehicles, data centers, and the power grid. Power electronics, which do things like modify voltages or convert between direct and alternating current, are everywhere. They’re in the power bricks we use to charge our portable devices; they’re in the battery packs of electric cars; and they’re in the power grid itself, where they mediate between high-voltage transmission lines and the lower voltages of household electrical sockets.

Innovative System Images Photosynthesis to Provide Picture of Plant Health

Crop imager could enable agricultural machinery that automatically responds to stressed plants. Researchers have developed a new imaging system that is designed to monitor the health of crops in the field or greenhouse. The new technology could one day save farmers significant money and time by enabling intelligent agricultural equipment that automatically provides plants with water or nutrients at the first signs of distress. With further development, the system has the potential to be used aboard unmanned aerial vehicles to remotely monitor crops.
