  Researchers from the University of St Andrews and the University of Cambridge have achieved a breakthrough in wireless optical communications by using OLEDs (organic light-emitting diodes)—commonly found in smartphone screens and televisions—as fast, long-distance transmitters for visible light communication (VLC), also known as Li-Fi. VLC uses light waves rather than radio frequencies to send [...]

  Defense Advanced Research Projects Agency (DARPA) Persistent Optical Wireless Energy Relay (POWER) program is bringing futuristic visions closer to reality by achieving record-setting results in long-distance, wirelessly beamed power. This initiative aims to revolutionize the delivery of electricity, particularly for military and humanitarian operations where the logistics of providing energy across challenging terrain are [...]

  In a recent research paper titled “A New Way to Understand the Color Rendition Performance of Multi-Primary Light Sources” published in Leukos, the researchers introduce a novel approach to evaluating and characterizing the color rendition performance of tunable, multi-primary light sources—a class of modern illumination technologies with significant applications in architecture, entertainment, and display [...]

By Bill Chan, President, LiteController Inc. Melanopic Equivalent Daylight Illuminance (M-EDI) is widely used to assess circadian-effective lighting, but is it truly optimized for human biological responses? What is M-EDI? Melanopic Equivalent Daylight Illuminance (M-EDI) is a metric used to evaluate how light impacts our circadian rhythms, based on the sensitivity of Melanopsin, a photopigment [...]

A new study was published last month, Non-Image-Forming Effects of Daytime Electric Light Exposure in Humans: A Systematic Review and Meta-Analyses of Physiological, Cognitive, and Subjective Outcomes, in the IES journal Leukos. Light exerts numerous nonvisual or non-image-forming, effects – such as its impact on melatonin suppression, circadian phase-shifts, sleep quality, and alertness. While research [...]

A recent study conducted by researchers at Shanghai Jiao Tong University School of Medicine has uncovered a potential link between blue light exposure and an increased risk of kidney stone formation, raising important questions about the health impacts of modern lighting and screen use. Kidney stones are a growing global health concern, traditionally associated with [...]

  In a groundbreaking study, scientists at the University of California, Berkeley, have developed a technique called “Oz” that allows the human eye to perceive a brand-new color, which they have named “olo.” This color is described as a blue-green or teal of unprecedented saturation-far more vivid than any color found naturally or previously seen [...]

Researchers at Ritsumeikan University in Japan as well as Colorado State University have developed a groundbreaking method that achieves complete breakdown of perfluoroalkyl substances (PFAS), commonly known as “forever chemicals,” using visible LED light at room temperature. This innovation represents an important advance in environmental remediation and sustainable fluorine recycling, addressing one of the most [...]

Researchers have achieved a groundbreaking milestone by transforming laser light into a supersolid—a quantum state that exhibits both crystalline solid structure and frictionless fluid flow. Published in Nature, this work marks the first time light has been manipulated into such a state, offering new avenues for quantum research and photonic technologies. What Is a Supersolid? [...]
