Electromagnetic fields stress living cells.

Electromagnetic
fields (EMF), in both ELF (extremely low frequency) and radio frequency
(RF) ranges, activate the cellular stress response, a protective
mechanism that induces the expression of stress response genes, e.g.,
HSP70, and increased levels of stress proteins, e.g., hsp70. The 20
different stress protein families are evolutionarily conserved and act
as 'chaperones' in the cell when they 'help' repair and refold damaged
proteins and transport them across cell membranes. Induction of the
stress response involves activation of DNA, and despite the large
difference in energy between ELF and RF, the same cellular pathways
respond in both frequency ranges. Specific DNA sequences on the
promoter of the HSP70 stress gene are responsive to EMF, and studies
with model biochemical systems suggest that EMF could interact directly
with electrons in DNA. While low energy EMF interacts with DNA to
induce the stress response, increasing EMF energy in the RF range can
lead to breaks in DNA strands. It is clear that in order to protect
living cells, EMF safety limits must be changed from the current
thermal standard, based on energy, to one based on biological responses
that occur long before the threshold for thermal changes.


"it´s clear"... estos hippys tecnófobos van a ser la muerte de todos nosotros.
