Welcome to Unseen in a new light podcast, for our second episode I will be talking about Biophotons describing what they are as well as explaining case studies and data showing why they are so important and why we felt like we needed to bring this information to light. Biophotons (from the Greek βίος meaning "life" and φῶς meaning "light") are photons of light in the ultraviolet and low visible light range that are produced by a biological system.
