The human body has long been studied through the lens of chemistry and electrical signaling, but an emerging field of research is adding a fascinating new dimension: light. Scientists have discovered ...

Life, for the most part, is bathed in light. The sun immerses the planet in energy that supports the vast majority of ecosystems that call Earth home. In a new study published in the journal iScience, ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists observed a radiant and intriguing physical phenomenon in mice and leaves that might suggest that all living things emit ...

Human bodies are not quite as dark as they look. A growing body of research suggests that living tissue constantly releases an ultraweak glow, a stream of photons that appears to switch off when life ...

Every living thing on Earth appears to carry a hidden shimmer, a vanishingly faint light that is woven into the chemistry of life itself. That glow is so weak that our eyes will never see it unaided, ...

Here’s an interesting question: are there optical communication channels in the brain? This may be a radical suggestion but one for which there is more than a little evidence to think it is worth ...

All living organisms emit a low level of light radiation, but the origin and function of these 'biophotons' are not yet fully understood. An international team of physicists, funded by the ...
