Hello everybody. I have a question to make which concerns not only biology but physics as well. When the cells of a living organism come in contact with a radio signal for instance, which carries artificial data can these data be proccesed or leave tracks in cellular level? Or could a tv programm carried in a radiowave be in someway understanable via cellular reactions?
I know that, in addition to our eyes, which can process visible light, there are some bird eyes that can process the smaller, ultraviolet waves (because of an extra pigment molecule, I think).
In contrast, it seems unlikely that cells, which are small, could ever process radiowaves, which are big. Radiowave telescopes have to be giant in order to recieve the radiowaves, and that is why radiowave telescopes tend to be earthbound.
The health effects of commonly encountered radio-frequency electromagnetic radiations (RF-EMR) from mobile phone exposures do exist. The evidence from this study points to the quite substantial hazard of RF-EMR from the mobile phone on passive avoidance behaviour and hippocampal morphology in rats.
The safety of human exposure to an ever-increasing number and diversity of electromagnetic field (EMF) sources both at work and at home has become a public health issue. To date, many in vivo and in vitro studies have revealed that EMF exposure can alter cellular homeostasis, endocrine function, reproductive function, and fetal development in animal systems. Reproductive parameters reported to be altered by EMF exposure include male germ cell death, the estrous cycle, reproductive endocrine hormones, reproductive organ weights, sperm motility, early embryonic development, and pregnancy success. At the cellular level, an increase in free radicals and [Ca2+]i may mediate the effect of EMFs and lead to cell growth inhibition, protein misfolding, and DNA breaks. The effect of EMF exposure on reproductive function differs according to frequency and wave, strength (energy), and duration of exposure. In the present review, the effects of EMFs on reproductive function are summarized according to the types of EMF, wave type, strength, and duration of exposure at cellular and organism levels.
