Durable Coating Self-Heals in 30 Minutes Upon Sunlight Exposure
DAEJEON, South Korea, Aug. 23, 2022 — Researchers at the Korea Research Institute of Chemical Technology (KRICT) developed a transparent protective coating material that can self-heal in 30 minutes when exposed to sunlight. According to the researchers, excellent durability of...
Wireless, Wearable Sensors-on-a-Chip Provide Precise Dosimetry at Multiple Wavelengths
EVANSTON, Ill., Dec. 11, 2018 — A wearable, battery-free sensor has been developed that can measure and monitor exposure to light across multiple wavelengths, from the UV to the VIS to the IR regions. The device, created by researchers at Northwestern University, can record up to...
Blue Light Excites Retinal, Intercepts Cellular Signaling in the Eye
TOLEDO, Ohio, Aug. 9, 2018 — An optical chemistry research study has shown how blue light from digital devices and the sun can cause the death of retinal molecules, increasing potential for age-related macular degeneration. Photoreceptor chromophore 11-cis retinal (11CR) and...
Blue Light Influences Cognition Even After Exposure Ends
TUCSON, Ariz., July 13, 2016 — Scientists have shown that a single exposure to blue wavelength light for a period of approximately one-half hour leads to measurable changes in brain activity in the prefrontal cortex when people engage in a cognitive task, even after light...
LED Exposure Impacts Milk Quality More Than Any Other Factor
ITHACA, N.Y., July 12, 2016 — A study to evaluate the effects of LED light on the perceived quality of milk shows that exposure to LEDs for even a few hours degrades the perceived quality of milk even more than the microbial content that naturally accumulates over time. The...
Early Light Refines Brain’s Circuitry for Vision
PROVIDENCE, R.I., June 9, 2011 — Two new studies from Brown University on different species and using different techniques show how nascent animal brains use light to construct their central vision system. Creatures are not born hard-wired to see. Instead, they depend on...
