Many people have not even heard about it, one mine presentation: " Biophotons are electromagnetic emission which occurs intracellularly and between cells, in all kinds of living organisms. They have been discovering and showing staggered throughout history but its study has become more visible for 40 years with the use of photo-multipliers. Some people place its origin in oxidative chemical reactions that occur in the mitochondria of cells and some people place its origin or at least its modulation in DNA and while those reactions are controlled in some way by the DNA the fact is that the spectrum covered by these biophotonic emissions (ranging from the UV to the near infrared) suggest that well may have two different origins (it has been speculated that UV can be modulated by DNA and near-IR generated in mitochondria). The characteristics of biophotonic light (besides its low intensity is why what has been slow to discover) are their coherence and similarities in several aspects to the laser light. Have been detected transmission characteristics of some kind of information within and between organisms, and has also been speculated that may be part of consciousness. It is noteworthy that both microtubules in cells and fibers of the extracellular matrix have characteristics that make them optimal for photon transmission. " And here the letters of one of the most prominent biophotons rediscoverer at the end of the last century, F.A. Popp, in 2008: " Biophotonic emition is measured to be much weaker compared to other types of radiation. Biophotons according to recent studies have a wavelength from 200 nm to 800 nm (0.2–0.8 μm) (Devaraj & Inaba, 1997; Kim, 2002.). They are usually being observed in the close UV range (from 300 nm to 400 nm) and visible optic range (from 0.38 μm to 0.75 μm) with frequencies ranges from 10−19 to 10−16 W/cm2 (approx. 1–1000 photons.cm-2.sec-1) (Inaba, 2000). This light intensity is much weaker than the one that may be seen in the perceptually visible and normal bioluminescence, but is detectable above the background of thermal or infrared (0.74–2.5 μm) radiation emitted by tissues at their normal temperature. F.A. Popp proposed that this type of light is not radiated in a dispersed way as daylight, but quite coherently maintaining order in the flow oscillations, stability and continuity of the phase difference of the amplitude of the total wave, e.g. it might be both semi-periodic and coherent (Popp et al., 1992). It is known that coherence is an ideal property of waves that enables stationary (i.e. temporally and spatially constant) interference. More generally, coherence describes all properties of the correlation between physical quantities of a single wave, or between several waves or wave packets (Beloussov et al., 2000). This may signify that biophotones in the light’s beam vibrate simultaneously, like in a laser beam that can indicate on information characteristics of the signal. The photon emission in its turn is weaker than normal bioluminescence because during that process individual photons are being emanated (Lin, 2006). The “delayed luminescence” is connected with hyperbolic relaxation of biological objects that is a characteristic active response of coherent states. In recent years the evidence has been found that the light has a high degree of coherence because of its photon count statistics, the spectral distribution, unstable decay behavior after exposure to light illumination, and its transparency through optically thick materials. Moreover, DNA is apparently an important source of biophoton emission, since conformational changes of DNA induced with 3,8-diamino-5-ethyl-6-phenylphenanthridinium bromide in vivo are clearly reflected by changes of photon emission in cells (Rattemeyer et al., 1981). The physical properties of the emission are described, using the DNA molecule as an exciplex ultraviolet laser system, where a stable state can be reached far from thermal equilibrium at threshold."

Interesting - a variant of bioluminescence, I suppose. One thing bothers me: the reference to laser behaviour. This requires a population inversion that is "discharged" by collective, thus coherent, stimulated emission. How is it proposed that a population inversion can be created and by what process would collective emission occur, without a reflecting cavity or its equivalent?
