3-D-printed glass enhances optical design flexibility

Lawrence Livermore National Laboratory (LLNL) researchers have used multi-material 3-D printing to create tailored gradient refractive index glass optics that could make for better military specialized eyewear and virtual ...

Bending light to engineer improved optical devices and circuits

Rainbows are formed when light bends—or refracts—as it enters and exits a water droplet. The amount that the light bends depends on the color of the light, resulting in white light being separated into a beautiful spectrum ...

Identifying communities at risk for impacts of extreme heat

An analysis of ways to measure a community's vulnerability to climate change suggests that California's current method may leave some at-risk communities behind in efforts to reduce health impacts of extreme heat. Lynée ...
