For the last few years, general scientific consensus has suggested the blue light spectrum coming out of our modern devices can significantly disrupt our circadian rhythms. To balance this, many ...

A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...

Surprisingly, some of the universe's brightest objects are black holes. As scorching gas and dust flow around and into a ...

Engineers are turning what used to be a bulky optics bench into something that fits on the tip of a finger, and the latest ...

Scientists have unraveled the evolutionary journey of a unique type of photosynthesis that allows some bacteria to harness far-red light, a region beyond the visible spectrum. This discovery could ...

A new single molecule can absorb the full spectrum of sunlight and turn it into valuable hydrogen. Freeing hydrogen to use as fuel is a major science holy grail in the 21st century. Costly, ...

I WOULD suggest that when your readers visit Paris they should take their pocket spectroscopes. They will find a very interesting spectrum in the electric lamps now being used for `lighting some of ...

How does color work, and how does the type of light source you use affect the colors you see? Appliance Science looks at the science of light and color. Richard Baguley Richard Baguley has been ...

About 2.5 billion years ago, a pigment called chlorophyll appeared in single-celled organisms, allowing them to capture energy in the form of light and convert it into sugars. This biochemical trick, ...
