Imaging the Secret Lives of Immune Cells in the Eye
Researchers in Rochester, New York (US) demonstrate a way to track the interactions of microscopic immune cells in a living eye without dyes or damage, a first for imaging science. Combining infrared videography and artificial... -
Nanoscale Machines Convert Light into Work
Researchers have developed a tiny new machine that converts laser light into work. These optically powered machines self-assemble and could be used for nanoscale manipulation of tiny cargo for applications such as nanofluidics... -
The Nobel Prize in Physics 2020
Three Laureates share this year’s Nobel Prize in Physics for their discoveries about one of the most exotic phenomena in the universe, the black hole. Roger Penrose showed that the general theory of relativity leads to the... -
RadarGlass: From vehicle headlight to radar transceiver
As a result of modern Advanced Driver Assistance Systems, the use of radar technology has become indispensable for the automotive sector. A wide range of systems for adaptive speed control, lane-change support, collision... -
Impurities Enhance Polymer LED Efficiencies
Polymer LEDs (PLEDs) are devices containing single layers of luminescent polymers, sandwiched between two metal electrodes. They produce light as the metal layers inject electrons and holes into the polymer, creating distortions... -
Fraunhofer ISE Receives f-cell Award 2020 for Fuel Cell Screen Printing Process
The Fraunhofer Institute for Solar Energy Systems ISE received the f-cell Award this year in the category "Research & Development". The prize distinguished their work on the development of flatbed screen printing... -
Multishot Lensless Camera Could Diagnose Disease and Make Skinnier Cellphones
A new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object is being developed by researchers at Penn State. The electric-field directed self-assembling...

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... -
Perovskite NIR LED with Record External Quantum Efficiency
Researchers at Linköping University (LiU) in Sweden have produced near-infrared (NIR) light-emitting diodes (LED) of perovskite with a record external quantum efficiency of 21.6%. Because perovskites have good light-emitting properties and... -
Optical Tweezers Use Fluid Flow Instead of Light
Researchers from the universities of Glasgow, Bristol and Exeter have collaborated to create an entirely new kind of optical tweezers that use fluid flow instead of light to control particles of any material and hold light-sensitive biological... -
First of its Kind Quantum Sensor to Detect Single Photons
A new, groundbreakingly effective sensor developed by researchers at the University of Waterloo in Ontario (Canada) is the first of its kind, based on semiconductor nanowires, that can detect photons. The research breakthrough promises to...
