We all have that favorite piece of clothing, and we're all familiar with the sinking feeling when we spill something on it. But now, new reports have revealed a simple way to remove pesky stains. ACS ...

LED therapy masks use specific light wavelengths for at-home skincare treatments. Red light is used to improve fine lines, while blue light targets acne-causing bacteria. Users should follow safety ...

Several pieces of evidence have suggested that blue light can inactivate various pathogenic bacteria. Previously in vitro and in vivo studies using blue light in the spectral range of 400–470 nm ...

Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...

A Rutgers-led team of scientists has developed an eco-friendly, very stable, ultra-bright material and used it to generate deep-blue light (emission at ~450 nm) in a light-emitting diode (LED), an ...

Three scientists who succeeded in inventing efficient blue light-emitting diodes (LEDs) where many companies had failed have won the Nobel Prize in Physics. The Royal Swedish Academy of Sciences on ...
