Malkemper EP, Eder SH, Begall S, Phillips JB, Winklhofer M, Hart V, Burda H. Magnetoreception in the wood mouse (Apodemus sylvaticus): influence of weak frequency-modulated radio frequency fields. Sci Rep. 2015 Apr 29;4:9917. doi: 10.1038/srep09917.

  • Wood mice exposed to a 0.9 to 5 MHz frequency sweep changed their preference from north-south to east-west. In contrast to birds, however, a constant frequency field tuned to the Larmor frequency (1.33 MHz) had no effect on mouse orientation. In sum, we demonstrated magnetoreception in wood mice and provide first evidence for a radical-pair mechanism in a mammal.Open Access Paper: 

  • In sum, we show that wood mice possess a magnetic sense that they use to position their nests along the NNE-SSW axis relative to the magnetic field. The NNE-SSW preference was not altered by RF fields delivered at the Larmor frequency, but was shifted by approximately 90° by a RF frequency sweep (0.9–5 MHz repeated at 1 kHz) at an intensity of only ~5% that of the Larmor frequency stimulus. 

  • The results point to the involvement of a radical pair mechanism, the first such evidence for a mammal, although further research is needed to provide a more thorough characterization of the underlying mechanism. 

  • The RF magnetic fields applied here have peak intensities below the ICNIRP guidelines for general public exposure (63, i.e., Brms = 0.92 µT/f [MHz], or Bpeak = 1.30 µT/f [MHz]) considered as harmless for human health. Yet, we show that they are sufficient to affect behaviour in a mammal.

Mobile phone mast effects on common frog (Rana temporaria) tadpolesElectromagnetic Biology and Medicine [2010, 29(1-2):31-35

  • Eggs and tadpoles of the common frog were exposed to electromagnetic radiation from cell phone antennas for two months, from the egg phase until an advanced phase of tadpole prior to metamorphosis. Results indicate that radiation emitted by phone masts in a real situation may affect the frogs development and may cause an increase in mortality of exposed tadpoles.
  • “This research may have huge implications for the natural world, which is now exposed to high microwave radiation levels from a multitude of phone masts.”

Wireless Radiation and our Environment

WiFi signals confuse birds, weaken the bees and even damage trees. In fact, the majority of research studies show that exposure to wireless damages the environment. Caring for this issue will help not only our children, but all life on our awesome earth.

Parents For Safe Technology

A review of the ecological effects of radiofrequency electromagnetic fields (RF-EMF) Environment International Volume 51, January 2013, Pages 116–140

  • A review of ecological studies from original peer-reviewed publications. RF-EMF had a significant effect on birds, insects, other vertebrates, other organisms and plants in 70% of the studies. Development and reproduction of birds and insects are the most strongly affected endpoints.

  • The growth of wireless telecommunication technologies causes increased electrosmog. Radio frequency fields in the MHz range disrupt insect and bird orientation. Radio frequency noise interferes with the primary process of magnetoreception. Existing guidelines do not adequately protect wildlife. Further research in this area is urgent.

  • “Conclusion: At the present time, there are reasonable grounds for believing that microwave radiation constitutes an environmental and health hazard….the precautionary principle is needed and should be applied to protect species from environmental non-thermal effects (Zinelis, 2010). Controls must be introduced and technology rendered safe to the environment, since this new ubiquitous and invisible pollutant could deplete the efforts devoted to species conservation.”

  • There is an urgent need for further research  and “of the 919 research papers collected on birds, bees, plants, other animals, and humans, 593 showed impacts, 180 showed no impacts, and 196 were inconclusive studies”.

  • “One can take the precautionary principle approach and reduce RF-EMF radiation effects of cell phone towers by relocating towers away from densely populated areas, increasing height of towers or changing the direction of the antenna.”
