Про антистоксово излучение, к примеру - слышал? А то, что интенсивность этого излучения клеток совершенно ничтожна, ни на какие мысли не наводит?
One of the more controversial discoveries is the observation that cells produce, transmit and perceive ultraweak electromagnetic radiation (also called ultraweak photon emission, low-level bioluminescence, and bio-electromagnetism). The controversy was instigated in 1923 by Gurwitsch (336) who reported that dividing Paramecia emit weak UV rays (luminescence) that are capable of stimulating cell division in other Paramecia. His results were supported by Alpatov & Nastjukova (337) who showed that the low intensity output from a broadband xenon arc lamp (visible and UV rays) increases the rate of cell division of Paramecia, whereas high intensities reduce it. Hollaender & Claus (338, 339), however, were unable to obtain a mitogenic effect in bacteria with either UV or visible light. Using sensitive detection techniques, Popp (340) and others have measured spontaneous emission of low intensity electromagnetic radiation (visible and UV) from many types of plant and animal cells including mammalian cells. The significance of these emissions, typically 10-100 photons per sec, is still under investigation.
Еще раз, медленно: в возможности испускания живыми организмами видимого света, даже достаточно интенсивного, сомневаться вообще не приходится - достаточно вспомнить про светлячков или гнилушки. В чём принципиальная проблема с испусканием ОЧЕНЬ СЛАБОГО ультрафиолета?
