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, ...

The brain uses two key pathways for neural communication—neurotransmitters and nerve impulses—but what if there was a third, unknown channel? A review article highlights growing research around the ...

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 ...

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 ...

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, ...

Did you ever have that feeling of a close connection with a person you just met? Can you sometimes sense the mood of another person without actually seeing them? It must be about qi or prana or auras ...
