Cell phone use in pregnancy may cause behavioral disorders in offspring: new study

Exposure to radiation from cell phones during pregnancy affects the brain development of offspring, potentially leading to hyperactivity, Yale School of Medicine researchers have determined.

The results, based on studies in mice, are published in the March 15 issue of Scientific Reports, a Nature publication.

"This is the first that to radiofrequency radiation from cellular telephones does in fact affect adult behavior," said senior author Hugh S. Taylor, M.D., professor and chief of the Division of Reproductive Endocrinology and in the Department of Obstetrics, & Reproductive Sciences.

Taylor and co-authors exposed pregnant mice to radiation from a muted and silenced cell phone positioned above the cage and placed on an active phone call for the duration of the trial. A control group of mice was kept under the same conditions but with the phone deactivated.

The team measured the brain electrical activity of adult mice that were exposed to radiation as fetuses, and conducted a battery of psychological and behavioral tests. They found that the mice that were exposed to radiation tended to be more hyperactive and had reduced memory capacity. Taylor attributed the behavioral changes to an effect during pregnancy on the development of neurons in the prefrontal cortex region of the brain.

Attention deficit disorder (ADHD), is a developmental disorder associated with neuropathology localized primarily to the same brain region, and is characterized by inattention and hyperactivity.

"We have shown that behavioral problems in mice that resemble ADHD are caused by cell phone exposure in the womb," said Taylor. "The rise in behavioral disorders in human children may be in part due to fetal cellular telephone irradiation exposure."

Taylor said that further research is needed in humans to better understand the mechanisms behind these findings and to establish safe exposure limits during pregnancy. Nevertheless, he said, limiting exposure of the fetus seems warranted.

First author Tamir Aldad added that rodent pregnancies last only 19 days and are born with a less-developed brain than human babies, so further research is needed to determine if the potential risks of exposure to radiation during human pregnancy are similar.

"Cell phones were used in this study to mimic potential human exposure but future research will instead use standard electromagnetic field generators to more precisely define the level of exposure," said Aldad.

They aren't even trying anymore are they?

How many mice were used in this farce of a study? If they had trained the mice to dance it would have been less wasteful.

Now I think I will go ask people if their mothers spent any time living under 15 foot wide cellphones while they were pregnant with them them.

I checked his link, it works and you can get in touch with him.
Here is the link to the entire study and references: Scientific Reports 2 : 312. DOI: 10.1038/srep00312 ...it works too.
The article appears to reflect cogent thinking, once you read it, but a contrary view could enlighten as well, oh yeah.
"...15 foot wide cellphones..." I did not quite get your meaning. The RF footprint for cell phone use, in a car with four occupants using a phone, a bus filled with ringing cellphones, on the street...people do not even make eye contact any more for use of cell phones..."15 foot" I really missed you on that part.
Get in touch with the writer and rap on this and then give us your point of view. I KNOW I would like to hear your side of things, Seany. (Cellphone RF effects are all so 'questionable.')

The solution is to restrict the mice to the use of land-lines.
Seriously, I would like to know exactly HOW they quantified 'hyperactivity' and 'memory capacity' in mice to a precision that yielded to statistical analysis and demonstrated a statistically significant difference, as well as what the environmental controls were that insured no confounding effects or extraneous forces occurred between birth and maturity in the subjects.

Sure, it's far from conclusive, but would you really ignore this evidence if you were pregnant? That just seems needlessly reckless given how easy it is to avoid your belly for only 9 months.

Strong RF affects biology, but we don't know everything about it. I think we have enough info to be cautious as individuals, but not enough to change public policy.

It's best to err on the side of caution and safety, rather than the possibility of producing a defective child. . .whether or not the study is of value or accurate.
The problem is that cellphone use is firmly entrenched in society and pregnant women are not necessarily going to give up their usage unless the study is confirmed by actual human results and not just in mice.

Hey ritchie speaking of defective baby brains did you forget you need to resolve this apparently bullshit statement of yours?
As I've said before, I will be planting sweet sorghum soon, and the resulting sugars will be fermented into ethanol...to store the ethanol locally and each one take out only as much as was put in.
-To which I aptly replied:
Funny. U of Arizona is only just now working on a pilot plant project for sweet sorghum. They've grown 40 acres (coincidence?) but couldn't manage the logistics for even this test project because the intermediate support is not yet available.

So whats the story ritchie? You really must dispel the suspicion that you pulled this out of what I must assume is a very AMPLE ass of yours.

if you want to see some real "behavioral disorder" go ahead and TRY to separate a woman from her cell phone

Thirty-three female mice were exposed throughout gestation (days 117) to radiation from muted and silenced 8001900Mhz cellular phones with a SAR of 1.6W/kg. The phones were positioned above each cage over the feeding bottle area at a distance of 4.522.3cm from each mouse


Three things come to mind. The SAR for most cellphones is much lower at 0.5 W/kg during use, because they do not use the full transmitting power except in poor reception, and a pregant woman would not keep a transmitting cellphone less than a foot away from the baby's brain for the entire 9 months, or even 17 days for that matter. As far as other peoples' phones go, the radiation flux decreases dramatically with distance.

Doubling the distance to the phone means reducing the radiation power per unit volume by almost 90%

These mice lived a good part of a month right next to an active transmitter that is three times stronger than a regular cellphone.

Cellphone microwave radiation has only one proven effect on people: it gives you research grants. For 30 years they've now tried to find something - anything - wrong with it, and every single study has always concluded with "further research is needed".

Just did a quick keyword search for the word "heat" and "temperature" and found no results. Could the heat be responsible for this article's effects and maybe the anecdotal brain tumor reports?

I've been having exactly the same problem on and off lately as well. I've also had the intermittent problem of getting a 404 gate error when I have tried to check who has been downranking whom. Anybody else having this kind of an issue? Best Regards, DH66
PS I agree with you guys that this was not a very realistic experiment. I classify it more as one simulating 'extreme conditions', to show that something is possible and to encourage more critical research. At least they aren't trying the usual BS (often subsidised by the telcos themselves) of telling us that they have *definitively proven* that cell-phones don't do any damage.

Hey, I just posted something, hit the "off" button on the filter to force a rather reluctant and slow loading process (never fails, also good for a page refresh/update without having to wait for a full reload) and suddenly this page was displaying correctly. The gate error has disappeared too. So not even a browser issue. If you are having this trouble, it might be worth a try. Regards, DH66

Actually they should do tests with high levels of radiation to see what effects one could possibly get.

Did you do the search from this section? If it doesn't work from medxp, try doing from the regular PO sites. It could be the same gremlins at work that are stuffing up the rating and quoting. BTW. Am I the only one who can't access their account thru medxp? The only way that I can do this seems to be either by hitting the 'back' button (if I accessed via a bookmark) or go back to the regular PO section. That's long-winded and annoying. And kind of user-unfriendly. Regards, DH66

Possible confounding factor.
Most cellphones have switching power supplies that generate high frequency audio noise. This noise is above the frequency people can hear, but that may not be the case with mice. Continuous irritating noise may affect the mice, both the mother and the offspring.

No, I did it on the nature.com article linked at the bottom of this abstract.

How does an experiment like this not control for heat? Not even mention it in their methodology? I'm pretty sure I've read elsewhere that one theory for the cell phone-tumor correlation is the sustained heat of the device next to your tissues.

Hey skultch did you see that ritchie created a sockpuppet with your name just to uprate himself and think nobody would notice? How pathetic is that?


Yeah, I don't care. I really don't understand why any of you guys care about ratings. I get the frustration with getting a 1 without a corresponding post to explain it; it's like someone saying you are wrong or dumb and refusing to say why. Other than that, what's the point? Don't get me wrong, I used to care. I'm sorry if this offends anyone, but I think I just grew up and got over it. Maybe I'm not more mature, but I just don't have the time to care anymore.

Even more probable than that, most cellphones have amplifiers and speakers, and even with a perfect amplifier it is going to pick up noise from the environment. Now, the study says the speaker was muted - how?

In any case, what happens if you put a cellphone next to a sound system: tah-ta-dah-dah-dah-dah...

I would assume a software mute toggle would affect the pre-amp and thus no interference could get through to the speaker, which is also probably powered down. I could be wrong.
