Why standard, cuff-based blood-pressure measurements are insufficient for some desired types of assessments. How electro-optical techniques can be used for consistent, real-time data. The results ...

New signal-processing algorithms have been shown to help mitigate the impact of turbulence in free-space optical experiments, potentially bringing 'free space' internet a step closer to reality. New ...

The oil industry put fiber-optic sensing cables downhole to better understand why hydraulic fracturing doesn’t free trapped oil at expected rates in shale reservoirs, but the massive streams of ...

Scientists have developed a new multi-layered metalens design that could revolutionize portable optics in devices like phones, drones, and satellites. By stacking metamaterial layers instead of ...
