Doctor: Health Risks Possible With Cell Phone Use
PITTSBURGH (KDKA) ― There is a new warning about the possible health dangers associated with cell phone use.
The Director of the University of Pittsburgh Cancer Institute and UPMC Cancer Centers has issued the new advisory.
Dr. Ronald Herberman is warning that the use of cell phones could have adverse health effects including cancer.
According to Dr. Herberman, the length of cell phone conversations should be limited or phones should be kept away from the head by using a headset or a speaker phone.
Dr. Herberman also says children should never use cell phones except in emergencies.

the focus is on the phones here. (so) let's remember that earlier post about intersecting signals from towers (and perhaps it's effect on more subtle things).
i'll admit tho, this got me at first. in a "that figures" kinda way...all i thought was, can't wait to drop this on the phone yappers at work. doh! |

Cell Phone Radiation Is Actually Not Bad For Us Now, It Prevents Brain Disorders
http://preventdisease.com/news/10/010710_cell_phone_radiation_not_bad_now.shtml
Marco Torres is a research specialist, writer and consumer advocate for healthy lifestyles. He holds degrees in Public Health and Environmental Science and is a professional speaker on topics such as disease prevention, environmental toxins and health policy.
Yet another ridiculous study out of the University of South Florida claims that cell phone radiation actually protects against brain disorders rather than cause them.
It’s another version of researchers promoting junk science at its best. The ludicrous study only done in mice, suggests that long-term exposure to electromagnetic frequencies (EMF) associated with cell phones may actually protect against, and even reverse, Alzheimer’s disease.
“It surprised us to find that cell phone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer’s symptoms,” said lead author Gary Arendash, PhD, USF Research Professor at the Florida ADRC. “It was even more astonishing that the electromagnetic waves generated by cell phones actually reversed memory impairment in old Alzheimer’s mice.”
The so-called researchers claim their study was “highly-controlled” and that they isolated the effects of cell phone exposure on memory from other lifestyle factors such as diet and exercise. Yes folks, we’re talking about the lifestyle factors of mice, but you can see where this is going.
So how did they achieve this magnificent feat you ask? Well, when scientists can’t get the results they want from animal testing, they genetically alter animals to achieve favorable results. This way, the biology of their lab rats is custom tailored to suit the objectives and conclusions desired by the scientists and their funding sources. It’s actually very common and this study is no different.
It involved mice, most of which were genetically altered to develop beta-amyloid plaques and memory problems mimicking Alzheimer’s disease as they aged. Think about what would happen if you radiated a genetically modified potato that was designed to be different than a potato found in nature. The cells of the genetically modified (GM) potato could react very differently from the natural potato to a given stimulus. They may be more susceptible or resistant to the radiated dose depending on how the GM potato was designed specifically for that purpose. The same principal can be achieved with rodents.
The conditions of the experiment were also simulative as no practical application on mice could ever mimic how humans use phones. The mice didn’t wear tiny headsets or have scientists holding cell phones up to their ears; instead, their cages were arranged around a centrally-located antenna generating the cell phone signal.
But wait, the researchers claim that they perfectly housed each mouse the same distance from the antenna and exposed them to electromagnetic frequencies typically emitted by a cell phone pressed up against a human head. Huh? They exposed tiny little mice to the same EMF as cell phones emitted to a human head? Wouldn’t that expose the mice to a lopsided amount of EMF comparatively by ratio if you were to quantify the head mass of a human and that of a mouse? Okay, perhaps they overlooked that this wouldn’t be very applicable to humans.
Or maybe not. They stated they used memory tests on the mice that were closely designed from a sensitive test used to determine if Alzheimer’s disease, or its very early signs (mild cognitive impairment), are present in humans. “Since we selected electromagnetic parameters that were identical to human cell phone use and tested mice in a task closely analogous to a human memory test, we believe our findings could have considerable relevance to humans,” Arendash said. Hmmm, so Arendash is suggesting that a sensitive test used to determine a complex human brain disorder like Alzheimer’s, can be reproduced in rodents? I would love to see that test.
They found that if cell phone exposure was started when the genetically-programmed mice were young adults — before signs of memory impairment were apparent — their cognitive ability was protected. Months of cell phone exposure even boosted the memories of normal mice to above-normal levels. The memory benefits of cell phone exposure took months to show up, suggesting that a similar effect in humans would take years if cell phone-level electromagnetic exposure was provided.
Are you starting to get the picture of how absurd this study and its objective is? Perhaps we could genetically alter humans now so they could boost their memory, protect their cognitive ability and prevent brain disorders, all from a few years of dedicated cell phone use.
Based on what the researchers claim are “promising and unexpected findings” in mice, they concluded that electromagnetic field exposure could be an effective, non-invasive and drug-free way to prevent and treat Alzheimer’s disease in humans. Wait, it gets better. They are also now evaluating whether different strengths of electromagnetic frequencies will produce a faster and even greater cognitive benefit. So the stronger the EMF the greater the benefit? I wonder if the heat in Florida makes researchers go nutty?
The researchers also found increases in brain temperature during the two one-hour periods when mice were exposed to electromagnetic waves each day. This increase in brain temperature was seen only in the Alzheimer’s mice, and only after months of exposure. So the normal mice didn’t have a increase in brain temperature after months of blasting them with high EMF doses? Those were some amazingly resilient normal mice.
“Our study provides evidence that long-term cell phone use is not harmful to the brain,” Dr. Cao said. “To the contrary, the electromagnetic waves emitted by cell phones could actually improve normal memory and be an effective therapy against memory impairment.”
I think Dr. Cao said it all. Improving memory and effective therapy against impairment….who could ask for more right?
This is one of the most obviously senseless, illogical and foolish studies I have ever seen. Not only is the construct of the study absurd, but the researcher’s discussions and conclusions are so outlandish and unsupported, that they make global warming studies actually look scientific.
I find it very suspicious that not even one of these authors had a disclosure statement.
Another disturbing fact was that this study was supported by Byrd Alzheimer’s Institute.
This is an obvious attempt by the cell phone industry to further warp (literally) and sway public opinion on the detrimental health effects of cell phone radiation which are increasingly catching the media’s attention.
Electromagnetic frequencies and radiation are emerging health problem of the 21st century.
“Cells in the body react to EMFs as potentially harmful, just like to other environmental toxins, including heavy metals and toxic chemicals,” said Martin Blank, PhD.
“Based on the existing science, many public health experts believe it is possible we will face an epidemic of cancers in the future resulting from uncontrolled use of cell phones and increased population exposure to W-iFi and other wireless devices.
Thus it is important that all of us, and especially children, restrict our use of cell phones, limit exposure to background levels of Wi-Fi, and that government and industry discover ways in which to allow use of wireless devices without such elevated risk of serious disease,” said David Carpenter, MD.
“Radio frequency radiation and other forms of electromagnetic pollution are harmful at orders of magnitude well below existing guidelines,” said Magda Havas, PhD.
“The overall problem with environmental electromagnetism is much deeper, not only of concern at power line frequencies, but also in the radio frequency range encompassing mobile phones.
Here the public's continuing exposure to electromagnetic radiation is largely connected to money.
Indeed the tens of billions of dollars in sales one finds in the cell phone industry makes it mandatory to corporate leaders that they deny, in knee-jerk fashion, any indication of hazard,” said Abraham R. Liboff, PhD .
Next they’ll be telling us that cell phone radiation can increase your income, boost your love life and make you fly.

Cell Phone Exposure May Protect Against and Reverse Alzheimer's Disease
http://www.sciencedaily.com/releases/2010/01/100106193217.htm
ScienceDaily (Jan. 7, 2010) — The millions of people who spend hours every day on a cell phone may have a new excuse for yakking. A surprising new study in mice provides the first evidence that long-term exposure to electromagnetic waves associated with cell phone use may actually protect against, and even reverse, Alzheimer's disease. The study, led by University of South Florida researchers at the Florida Alzheimer's Disease Research Center (ADRC), was published January 6 in the Journal of Alzheimer's Disease.

"It surprised us to find that cell phone exposure, begun in early adulthood, protects the memory of mice otherwise destined to develop Alzheimer's symptoms," said lead author Gary Arendash, PhD, USF Research Professor at the Florida ADRC. "It was even more astonishing that the electromagnetic waves generated by cell phones actually reversed memory impairment in old Alzheimer's mice."
The researchers showed that exposing old Alzheimer's mice to electromagnetic waves generated by cell phones erased brain deposits of the harmful protein beta-amyloid, in addition to preventing the protein's build-up in younger Alzheimer's mice. The sticky brain plaques formed by the abnormal accumulation of beta amyloid are a hallmark of Alzheimer's disease. Most treatments against Alzheimer's try to target beta-amyloid.
The highly-controlled study allowed researchers to isolate the effects of cell phone exposure on memory from other lifestyle factors such as diet and exercise. It involved 96 mice, most of which were genetically altered to develop beta-amyloid plaques and memory problems mimicking Alzheimer's disease as they aged. Some mice were non-demented, without any genetic predisposition for Alzheimer's, so researchers could test the effects of electromagnetic waves on normal memory as well.
Both the Alzheimer's and normal mice were exposed to the electromagnetic field generated by standard cell phone use for two 1-hour periods each day for seven to nine months. The mice didn't wear tiny headsets or have scientists holding cell phones up to their ears; instead, their cages were arranged around a centrally-located antenna generating the cell phone signal. Each animal was housed the same distance from the antenna and exposed to electromagnetic waves typically emitted by a cell phone pressed up against a human head.
If cell phone exposure was started when the genetically-programmed mice were young adults -- before signs of memory impairment were apparent -- their cognitive ability was protected. In fact, the Alzheimer's mice performed as well on tests measuring memory and thinking skills as aged mice without dementia. If older Alzheimer's mice already exhibiting memory problems were exposed to the electromagnetic waves, their memory impairment disappeared. Months of cell phone exposure even boosted the memories of normal mice to above-normal levels. The memory benefits of cell phone exposure took months to show up, suggesting that a similar effect in humans would take years if cell phone-level electromagnetic exposure was provided.
Based on their promising and unexpected findings in mice, the researchers concluded that electromagnetic field exposure could be an effective, non-invasive and drug-free way to prevent and treat Alzheimer's disease in humans. They are currently evaluating whether different sets of electromagnetic frequencies and strengths will produce more rapid and even greater cognitive benefits than those found in their current study.
"If we can determine the best set of electromagnetic parameters to effectively prevent beta-amyloid aggregation and remove pre-existing beta amyloid deposits from the brain, this technology could be quickly translated to human benefit against AD" said USF's Chuanhai Cao, PhD, the other major study author. "Since production and aggregation of β-amyloid occurs in traumatic brain injury, particularly in soldiers during war, the therapeutic impact of our findings may extend beyond Alzheimer's disease."
The memory test used to evaluate the effects of cell phone exposure in mice was closely designed from a sensitive test used to determine if Alzheimer's disease, or its very early signs (mild cognitive impairment), are present in humans. "Since we selected electromagnetic parameters that were identical to human cell phone use and tested mice in a task closely analogous to a human memory test, we believe our findings could have considerable relevance to humans," Arendash said.
The researchers found a slight increase in brain temperature during the two one-hour periods when mice were exposed to electromagnetic waves each day. This increase in brain temperature was seen only in the Alzheimer's mice, and only after months of exposure. The researchers suggest the increase in brain temperature helped the Alzheimer's brain to remove newly-formed beta-amyloid by causing brain cells to release it.
The researchers were particularly surprised to discover that months of cell phone exposure actually boosted the memory of non-demented (normal mice) to above-normal levels. They suspect that the main reason for this improvement involves the ability of electromagnetic exposure to increase brain activity, promoting greater blood flow and increased energy metabolism in the brain. "Our study provides evidence that long-term cell phone use is not harmful to brain," Dr. Cao said. "To the contrary, the electromagnetic waves emitted by cell phones could actually improve normal memory and be an effective therapy against memory impairment."
"It will take some time to determine the exact mechanisms involved in these beneficial memory effects," Arendash said. "One thing is clear, however -- the cognitive benefits of long-term electromagnetic exposure are real, because we saw them in both protection- and treatment-based experiments involving Alzheimer's mice, as well as in normal mice."
Previous human studies of electromagnetic waves from cell phones involved only brief exposures given to normal humans. While some studies reported small improvements in attention or memory (not enough to impact daily life), others reported no memory effects from short-term exposure. The new study by Arendash, Cao, and their colleagues is the first to investigate the effects of long-term electromagnetic exposure over many months on memory function in either humans or animals. The findings indicate that "long-term" exposure to cell phone level electromagnetic waves is needed to observe enhanced memory in normal or memory-impaired mice.
The USF researchers began investigating the effects of cell phone use on Alzheimer's disease several years ago, after several observational studies in humans linked a possible increased risk of Alzheimer's with "low-frequency" electromagnetic exposure -- like the energy waves generated by power and telephone lines. However, cell phones emit "high-frequency" electromagnetic waves, which are very different because they can have beneficial effects on brain cell function, such as increasing brain cell activity, Arendash said.
There has been recent controversy about whether electromagnetic waves from cell phones cause brain cancer. Some researchers argue that the risk of glioma (40 percent of all brain tumors) doubles after 10 or more years of cell phone use. However, others argue that since the overall lifetime risk of developing a brain tumor of any type is less than 1 percent, any doubling of this risk would still be very low. Groups such as the World Health Organization, the American Cancer Society, and the National Institutes of Health, have all concluded that scientific evidence to date does not support any adverse health effects associated with the use of cell phones. Consistent with the view of these organizations, the researchers found no autopsy evidence of abnormal growth in brains of the Alzheimer's mice following many months of exposure to cell phone-level electromagnetic waves. They also found all major peripheral organs, such as the liver and lungs, to be normal.
The research was conducted by an interdisciplinary group of neuroscientists, electrical engineers, and neurologists from universities in Japan and China as well as from the Florida ADRC at the University of South Florida. The study was supported by funds from the Florida ADRC, a statewide project sponsored by the National Institute on Aging, and the USF Health Byrd Alzheimer's Institute.
