Cell Phone Exposure May Prevent and Reverse Alzheimer's Disease
After
years of being told that cell phone use is bad for you here is some good news
I just
read cell phone exposure may prevent and reverser Alzheimer’s disease
on
scitech-news (one of my research junkie sites.) Here is the link and the
article.

Cell
phone exposure may prevent and reverse alzheimer’s disease
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 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.

How to Avoid a Hug
This is an excerpt from Patti's new book "SNAP Making the Most of First Impressions, Body Language and Charisma" coming out this Fall
The Hug Dodge
So, you’re not a hugger and this whole hugging thing makes you a bit uneasy.
There are many motivations for dodging a hug and more than one method to do it.
It was front-page news in the Irish press with Bono, of the rock group U2 admitted
that he dodged a hug from then-President George W. Bush by jumping behind a
podium on the stage as the affectionate Bush came near him. Bono said he didn’t
feel like being the recipient of a hug from someone he disagreed with on so
many things.

I’m a hugger, so I don’t worry about people hugging me. But I know there have
been times when someone didn’t want to hug with me. Not everyone is a hugger.
When you hug, you expose the front of your body, opening all of your body
windows. It can make some people feel vulnerable. Others feel that hugs are too
personal and intimate and even too sexual for everyday interactions in business
and with acquaintances. Thankfully, their body language cues will let you know
very quickly whether they are huggers.
What if I don’t want a hug?
Carol, a pharmaceutical sales rep in my sales presentation skills class asked,
“What if I don’t want a hug? Some of the physicians I call on immediately give
me a hug and I am just not into that.” This is a frequent question for
women in business. The good news, Carol and all, “I am not a hugger” gals and
guys, there is a systematic technique to avoid the hug.
If you see the potential hugger with both hands and arms raised and chest
thrust out in the “hug” position, do the following:
1.
Break eye contact
2.
Step forward on your right foot
(This is your “handshaking foot” – the foot that normally moves first for a
handshake)
3.
Present only the right side of
your body, which effectively closes off your body windows
4.
Extend your right hand for a
handshake. (You can choose to make eye contact again at this point)
5.
After touching, step back
outside the intimate zone of space to signal you are done, and you don’t want
to follow the handshake with a hug. This step also sends the signal that not
only is the hug unwanted now, but also unwanted in the future.
If extending the arm and presenting the right side doesn’t stop
the hugger, wrap your left arm around the person’s shoulder. This way it
becomes a side-to-side hug rather than a frontal hug. You can also pat their
back or shoulder to insure you indicate you don’t want a sexual interaction.
The hug dodge does two things:
1.
It signals in those important
milliseconds that you are initiating a handshake interaction.
2.
It closes and protects the
windows of your body
Macey, a drop-dead gorgeous client of mine came in for a coaching
session after receiving the hug dodge training in our previous session. She
said, “I feel so empowered. Yesterday I was at a meeting. My boss’s boss, who
goes in for the really uncomfortable, feel you up kind of hug approached me
with his arms out at the meeting last week. I was able to use the hug dodge to
change it to a much more comfortable handshake. I realized at once how
powerless and uncomfortable I typically feel when I have had to interact with
him after one of his inappropriately sexual hugs.”
