Amid high expectations for quantum technology, a new paper in Science reports proven quantum advantage. In an experiment, entangled light lets researchers learn a system's noise with very few measurements.

Researchers at Concordia and Qatar University have created a low-cost sensor system that tracks indoor air quality in real time.

The devices are built on tiny, affordable computers often used in research and do-it-yourself projects. Hooked up to sensors, they measure carbon dioxide, fine particles and nitrogen dioxide and volatile organic compounds (VOCs) like benzene, formaldehyde and acetone.

Data is sent wirelessly to an online dashboard, where users can view live charts and air quality indexes.

University of Utah engineers develop a novel high-speed, high-def hyperspectral video camera that captures both color and fine spectral details in a single snapshot, producing a ‘spectral fingerprint’ for every pixel.

MIT researchers identified mucins that defend against Salmonella and other bacteria that cause diarrhea. They now hope to create synthetic mucins that could help prevent or treat Salmonella and other foodborne infections.
