Last year, researchers at the Rush University Medical Center in Chicago showed that human cells in culture could synchronize their internal chemical processes even though they were mechanically, chemically, and electrically isolated from one another. The cells, it seemed, were communicating through the exchange of photons.

Various other groups have shown similar effects. Many cells seems to produce optical and UV photons at about 10 photons per square cm/s, a rate that cannot be explained by ordinary thermodynamic emissions. Other evidence indicates that this form of optical communication can increase the rate of mitosis in cells by up to 50 percent.

So how do they do it? Today Sergei Mayburov at the Lebedev Institute of Physics in Moscow puts forward the idea that optical communication is a natural process in many cells that can be explained by the way we already know many cells to function.

He points out that biologists have long known that photons play a central role in the biochemistry of many plant and bacterial cells. The basic idea, laid out in the 1960s, is that optical or UV photons enter a cell and stimulate the creation of excitons, electron-hole pairs, on certain long chain molecules. The exciton travels along the molecule, influencing the way it reacts with other species within the cell. This is the basic theory behind photosynthesis.
