It has been well established in the literature that ELF electromagnetic fields and higher powered fields can stimulate microbial growth both Earth and in space. So why is it that this seems to fall well below most infectious disease experts radar? Could it be that the published data is just not well known because most of this data is published in bio-physics and in medical space journals? Today, on Earth the ionosphere has millions of times more radiation from man made devices and is more space like than it is native. Might this be why we see more mitochondrial diseases? Most microbes are prokaryotes or eukayotes with mitochondria. Is this why this occurs? Metabolism is the process by which cells convert relatively simple extracellular nutrients into energy and building blocks necessary for their growth and survival. In many cells stressed by nnEMF, metabolism is dramatically altered compared with normal cells.
