Researchers develop 3D printed acoustic metamaterials that can be switched on and off remotely using a magnetic field. Researchers have been pushing the capabilities of materials by carefully designing precise structures that exhibit abnormal properties that can control acoustic or optical waves. However, these metamaterials are constructed in fixed geometries, meaning their unique abilities are always fixed. Now, new 3D printed metamaterial developed by a team led by University of Southern California researchers can be remotely switched between active control and passive states.

Evening types have 10% higher risk of dying than morning counterparts. Night owls” – people who like to stay up late and have trouble dragging themselves out of bed in the morning – have a higher risk of dying sooner than “larks,” people who have a natural preference for going to bed early and rise with the sun, according to a new study from Northwestern Medicine and the University of Surrey in the United Kingdom (UK). In the study sample, 50,000 people were more likely to die in the 6½ -year period sampled.

“Night owls trying to live in a morning lark world may have health consequences for their...

Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones. The technique improves the resolution and color details of smartphone images so much that they approach the quality of images from laboratory-grade microscopes.

The advance could help bring high-quality medical diagnostics into resource-poor regions, where people otherwise do not have access to high-end diagnostic technologies...

The International Astronomical Union (IAU), the internationally recognized authority for naming celestial bodies and their surface features, recently approved a dozen names proposed by NASA’s New Horizons team, which led the first reconnaissance of Pluto and its moons in 2015 with the New Horizons spacecraft...
