Cancer is a product of policies on energy, buildings, food, and manufacturing.

February 14, 2017

Much of the past effort against cancer has fixated on the wrong enemies, with the wrong weapons. While scientific research concentrates on the genome within, we are ignoring the exposome—all that we breathe, drink, eat and absorb through our skin. As President Bush’s Cancer Panel reminded us in 2010, the great majority cases of cancer occur in people born with healthy genes as a result of carcinogenic exposures at work, home, and school. The Hill.

ELF exposure from mobile and cordless phones for the epidemiological MOBI-Kids study.

February 7, 2017

Environment International.

Investigation of terahertz radiation influence on rat glial cells.

Effects of extremely low-frequency electromagnetic field on expression levels of some antioxidant genes in human MCF-7 cells.

January 27, 2017

Long-term exposure to 835 MHz RF-EMF induces hyperactivity, autophagy and demyelination in the cortical neurons of mice.

January 27, 2017

RF-EMF exposure led to myelin sheath damage and mice displayed hyperactivity-like behaviour. The data suggest that autophagy may act as a protective pathway for the neuronal cell bodies in the cerebral cortex during radiofrequency exposure. The observations that neuronal cell bodies remained structurally stable but demyelination was induced in cortical neurons following prolonged RF-EMF suggests a potential cause of neurological or neurobehavioural disorders. Science Reports.
