DNA breaks: Microwave News Article Archive (2004 - )
Very low SARs lead to DNA breaks: 0.09 W/Kg @900 MHz and 0.169 W/Kg @1.8 GHz. Damage “more pronounced” at 1800 MHz. (Allium cepa = onion)
In summary, our evidence supports the hypothesis that sustained whole-body RF-EME is capable of inducing a state of oxidative stress in the male germ line, a cell vulnerable to the effects of ROS. … Furthermore, our data further implicate the mitochondria as the target for RF-EME biophysical interaction, with a consequential elevation of mitochondrial ROS generation being linked to reduced motility and elevated oxidative DNA damage and DNA fragmentation in the spermatozoa of exposed male.” From Australia. Open access.
This study shows “a positive correlation betwen duration of exposure and DNA damage.”
“Induced oxidative stress causes DNA damage in germ cells, which alters cell cycle progression leading to low sperm count in mice.” These changes are reversible (from Assam University, India; open access).
“Our main finding was the increased oxidative DNA damage to brain after 10 days of exposure with the decreased oxidative DNA damage following 40 days of exposure compared to their control groups.” This is yet another research paper from Turkey.
“[H]ands-free devices might reduce the MPR exposure intensity to the human head. However … the male reproductive system may be put into risks. Thus, it is important and urgent to establish feasible and effective strategies to prevent reproductive impairment following daily exposure to MPR. Significantly increased levels of DNA damage in the “dialing” and “dialed” modes were found in the present study…”
“In conclusion, two independent attempts failed to reproduce genotoxic effects of RF-EMF in HL-60 cells as reported by the REFLEX project. These repeat experiments were performed under the same experimental conditions as the original experiments and one part of the repeat study was performed by the scientists who also generated the REFLEX data.”
“Taken together, this suggests that the low intensity radiation emitted by a commercial GSM 900 MHz cell phone can result in either decrease of DNA strand breaks; or otherwise induce substantial DNA damage in cells of the developing bird embryo depending on the duration of the exposure. See also the group's earlier paper in Electromagnetic Biology and Medicine.
“Our study shows that exploratory activity, which is associated with physiological increases in neuronal activity and the encoding of new information, causes widespread increases in neuronal DSBs.”

We haven't posted many new items recently because we've been too busy fixing up the new Web site. In the process, we've been rereading many of our old stories. Last night, we came across an item from five years ago under the title "Cell Specific Responses to RF." It highlighted some new research from Finland, which found that cell phone radiation affected the activity of ODC, a biologically important enzyme, in...
Next Sunday, the New York Times Magazine will feature a long piece titled "Do Cell Phones Cause Brain Cancer?" by Siddhartha Mukherjee (it's already on the Times' Web site). It's a well-written article, as might be expected by his well-received book, Emperor of All Maladies: A Biography of Cancer. Yet an important part of the story is missing: the politics of cell...
If you want to see just how misguided the ICNIRP enterprise really is, take a look at its new EMF exposure guidelines in the December issue of Health Physics. [See also our November 10 post.]
Start at the end with the footnote that discloses the composition of its five-member ELF Task Group (p.830...
