Dasdag S. et al 2015. Effects of 2.4 GHz radiofrequency radiation emitted from Wi-Fi equipment on microRNA expression in brain tissue. Int J Radiat Biol. 91(7): 555-561. http://www.ncbi.nlm.nih.gov/pubmed/25775055 MicroRNAs (miRNA) play a paramount role in growth, differentiation, proliferation and cell death by suppressing one or more target genes. However, their interaction with radiofrequencies is still unknown. The aim of this study was to investigate the long-term effects of radiofrequency radiation emitted from a Wireless Fidelity (Wi-Fi) system on some of the miRNA in brain tissue. RESULTS: The results revealed that long-term exposure of 2.4 GHz Wi-Fi radiation can alter expression of some of the miRNAs such as miR-106b-5p (adj p* = 0.010) and miR-107 (adj p* = 0.005). We observed that mir 107 expression is 3.3 times and miR- 106b-5p expression is 3.65 times lower in the exposure group than in the control group. However, miR-9-5p, miR-29a-3p and miR-125a-3p levels in brain were not altered. CONCLUSION: Long-term exposure of 2.4 GHz RF may lead to adverse effects such as neurodegenerative diseases originated from the alteration of some miRNA expression and more studies should be devoted to the effects of RF radiation on miRNA expression levels. ------------------------------------------------------------------------------------------------------------------------------------------------ Akar A. et al., 2013.

You could compare it to passive smoking”
Dr. Franz Adlkofer at the Harvard Law Center for Ethics Lecture in 2011 discusses how he was unjustly accused of scientific fraud for his REFLEX study findings that cell phone radiation damages DNA. In this lecture he describes the institutional corruption and Industry involvement that led to accusations that his work was fraudulent. He was later exonerated and the accusations entirely dismissed by an ethics panel after an investigation showed that these accusations were unfounded. Listen to him describe the results of his research here in 2010. Watch him talk here. |

You should move to Nepal or some far off place with no technology, if you are worried about the effects of WiFi...or just take another Xanax.
The organic pesticides used on the organic food you feed your kids is probably more likely to harm them, since they are not regulated. |

| Op, you were doing so well, but alas you are back to wall of text posts. at least you made it 3 pages. |

| Cell phones are less regulated than pesticides. |

This issue is so complicated, you need far more than 3 pages.
Hear the history from Dr. George Carlo of how industry was able to get this technology to market before it was properly tested and how research findings have been suppressed since. You may also wish to read his book, "Cell Phones: Invisible Hazards in a Wireless Age (Avalon, 2001)". |

| This guy used to work for the wireless industry heading its 28 million dollar research program. The found DNA damage and stopped the research. |

To keep my children safe, I home-churn their butter from my own flock of virgin cows. Not virgin as in not sexually active, but as in never exposed to poisonous wifi. Then I store the butter in containers of tin I mine myself. Some people say tin mining is bad for the environment, but my kids have enjoyed the pretty rainbow colors in the waste water pond the mine created in our backyard. |

Nothing is less regulated than organic farm's use of pesticides.

nope.
cell phones and wireless got a free pass. premarket testing and post market surveillance ? NOPE the FDA and EPA have nothing to say. They tried but cant. The FCC is in charge. Same as pesticides in terms of the revolving door of industry and government--that the head of the FCC is the prior head of the Wireless Industry. THERE WAS NO PREMARKET TESTING . The "low level exclusion" allows for NO Health Testing before new tech comes on the market. Case in point, 5G Its being installed in schools nationwide yet there are only a handful of studies on 5G. opps- those show serious problems -but since no one is regulating it- this research means nothing. |

Here is the guy in charge of the issue in the USA.
Please note he is the former head of the Wireless Industry Trade Group- a powerful Lobby Group. |
