Cells May Communicate Through Light
SilverLobe writes "The hypothesis that living cells may use photons for communications has been on the fringes of cell biology for a while. No proof positive exists, but there is some strong circumstantial evidence. Byte Size Biology reports on a simple experiment that shows how the unicellular protozoan Paramecium may use so called 'biophotons' to signal for growth and feeding. The original academic paper in PLoS ONE concludes: '... not all cellular processes are necessarily based on a molecule-receptor recognition. The non-molecular signals are most probably photons. If so, cells use more than one frequency for information transfer and mutual influence.'"
