Brain Research Advances with Light-Based Technologies
Common methods of brain imaging present many challenges: some are invasive, others may contain harmful radiation, and many are difficult to use or require the patient to remain absolutely still throughout the process. Today researchers are... -
Advancements in Lighting Technologies
It has been nearly 200 years since the first constant electric light was demonstrated, spurring researchers throughout the world to advance the technology that brought illumination to homes and businesses.While the light that glows in our homes has... -
Light Technologies in the Fight Against COVID-19
Nearly a year into the COVID-19 pandemic, and while far too many people have lost their lives or are suffering long-term symptoms, today’s light-based technologies offer hope by advancing methods of disinfection, diagnostics, treatment and... -
Optical Tools Enable the Study of Microplastics
Plastics have only been around since the 1950s and yet they’re everywhere: scattered in our lakes, rivers, floating on the top of oceans, and dropping to the bottom. Back in the 1950s and 60s, plastics were hailed as a useful invention, used... -
Light Research Advances Medical Diagnostics & Health
Light technologies are increasingly contributing to our health and longevity. While, for example, cancer is among the leading causes of death worldwide, death rates for individual cancer types have declined in part due to advanced research on light... -
Thin Film Hides Objects from Infrared Detectors
Researchers at the Chinese Academy of Sciences have developed an aerogel film made of DuPont Kevlar fibers that makes objects invisible to infrared detectors. A successful method for hiding objects from heat-sensing cameras could be... -
Measuring and Self-Adjusting Spectral Power Distribution of LED Systems
Researchers from the Catalonia Institute for Energy Research (IREC) at the University of Barcelona and its spin-off Ledmotive Technologies in Spain have combined two computational methods to enable solid-state lighting (SSL) to measure and...
