MICROWAVE RADIATION IS HERE
"Why isn’t he more careful when pointing that laser beam?” I wondered during a recent lecture. The speaker was careless with the red beam, casting it about before pointing it at the screen.
I knew lasers could damage eyes. When used for treating medical problems, protective glasses must be worn, but I had no idea whether the use of a laser pointer was dangerous. Now I know.
Dr. Martin K. Schmid, an ophthalmologist at Lucerne Cantonal Hospital in Lucerne, Switzerland, reports in the New England Journal of Medicine the case of a 15-year-old boy who wanted to have a little fun. So he purchased a laser, thinking he would burn a hole in his sister’s sneakers and pop balloons.
Later, this teenager became more adventuresome. He decided to create a laser show, using it in front of a mirror. It was a dangerous decision. In the process of becoming a movie director, he zapped his eyes several times with the laser beam. He soon discovered he had lost some of his vision and was afraid to tell his parents what had happened.
Two weeks later, Dr. Schmid and his ophthalmology colleagues discovered the boy’s left eye was so badly damaged he could not count fingers more than a meter away (about three feet).
Eye examination showed a dense retinal hemorrhage in the left macula. The macula is the part of the eye that provides central vision and allows you to see another person’s eye at 20 feet. Loss of this vision means you can no longer read. He had also lost some vision in his right eye.
A four months’ healing process had helped the boy regain some of his eyesight. But he continued to have blind spots in his vision due to the destruction of cells in the retina, the back part of the eye. The retina sends visual messages to the brain. This tragedy could have been avoided.
So what should parents and teenagers know about laser pointers that are shaped like pens? Dr. Schmid says that most lasers are not high-powered, having only an output of 5 milliwatts. And that those in the range of one milliwatt are generally considered safe.
But the word “generally” worries me. It should also concern parents. Under ideal circumstances children are saved from laser injury due to a normal reaction to light. If we encounter a bright object, such as a laser beam, we normally blink, saving the eye from damage.
But assuming this will happen is problematic. Young children are curious and may decide to stare at a bright object for a period of time. Their prolonged curiosity could result in loss of vision even from low-power lasers.
Besides, it appears there’s a bit of the Wild West in the lack of government control in the selling of laser devices. For instance, it has been “generally” believed that laser devices powerful enough to damage the eye were only available to the military.
But Dr. Schmid reports that the laser acquired by this 15-year-old boy had a power of 150 milliwatts. And there are even stronger lasers sold on the Internet in the range of 700 milliwatts. Websites also advertise laser swords that are supposed to be fun toys!
I find it ludicrous that laser devices are allowed to be sold without a big red danger sign on them. Surely it’s reasonable to ask, how can a child tell a harmless laser pointer (if there is one) from a dangerous laser?
There are other problems. A U.S. contact told me that since 2004, there have been 2,800 incidents of laser beams being directed at landing aircraft in the United States. This is a senseless act.
The chance of damaging eyesight is minimal, as the speed of the plane and short duration of the beam protects the pilot. But this evil practice can cause sudden “flash blindness” at a critical time during landing.
The constant message is that there are many ways for children to be injured. Some we cannot control, but good sense should be able to stop laser-eye tragedies.

It Just Makes Sense – The Link Between Wireless Technology and the Rise in Autism
By Nancy Sarangan
Autism is an increasingly common neurological disorder that usually results in abnormal development of social interaction, communication skills and processing of sensory information. There is a considerable amount of debate and scientific study on the cause of autism and parents are growing increasingly impatient for answers. Could this be part of the puzzle?
When my daughter was diagnosed with autism, I wasn't very surprised. She had been displaying many of the signs for some time: mainly, the hands flapping, and the delay in language skills. Like any parent facing this, I wondered how and where all of this could have started.
I had done the research regarding the theories on autism – and my daughter, Kiyana, was the exception to almost all of them: (1) she has never been vaccinated, (2) she was exclusively breastfed, (3) she has never had an ear infection, (4) she has never taken any antibiotics, (5) she has never had any dairy products, (6) I avoided fish and shellfish during pregnancy, (7) took large doses of all the prenatal vitamins, and (8) I wasn’t given pitocin during labor. All the commonly attributed factors did not seem to apply to her.
Then, in November of 2007 a study came out describing a possible link between autism and microwave electro-magnetic radiation (EMR) the high frequency microwaves emitted by cell phones and other forms of wireless technology  The study suggested that EMR inhibits the nerve cell’s ability to clear toxins – most notably heavy metals – from the body, which thereby augments the onset of autistic symptoms. Biomedical researchers have found that people with autistic spectrum disorders have a difficult time efficiently excreting toxins from the body, a process known as methylation. The researchers in this EMR-Autism study set out to find out the cause of this impairment.
Essentially, excretion of toxins – specifically heavy metals – was tested by taking skin, urine, hair, and stool samples from children with autism. Initially, most of the subjects excreted very low levels of heavy metals. However, according to the test results, with a controlled reduction of exposure to EMR in the treatment areas and the subjects’ homes there was a demonstrable increase over time in the levels of heavy metals excreted. Thus, it was found that by diminishing the patients’ EMR exposure, their ability to detoxify metals from the body increased. The study concluded that exposure to EMR could impair a person's ability to detoxify heavy metals from the body.
The science and logic here was hard for me to reject. For us, the conclusions of the study made a lot of sense. We were among the early adopters of modern technology. We abandoned our landline phone in favor of cell phones well before that was a popular practice. From WiFi to wireless video baby monitors, we had them all. I had heard about cell-phone risks, but I assumed they were minimal and actually believed they were limited to only when holding the phone to one’s head or another body part for extended periods of time. I certainly never would have expected a home WiFi system to have any effect on her. A wireless baby monitor a few inches from where she slept that we virtually never turned off only seemed like what every responsible parent would use. Yet, here I was faced with some pretty harsh evidence that these may have been the “things” contributing to her autism.
Moreover, the numbers simply add up. Looking at the increase in the prevalence of autism over the past twenty to thirty years and then at the increase in the numbers of cellular-telephone subscribers, the parallels are hard to ignore. A study from the journal Medical Hypothesis entitled “Out of time: A possible link between mirror neurons, autism and electromagnetic radiation,” by Ian M. Thornton  showed the correlation between children with a diagnosis of autism attending US schools and US cellular phone sales, during the period 1992–2003. The correlations between the two were quite substantive.
We were naturally looking for only those things we can sense with our five senses of smell, taste, touch, sight, and sound. However, we were leaving out one thing -- the invisible threat – the threat of EMR which can affect us in ways similar to chemical substances. And their impact – if one takes a serious look at all the research out there – appears to be quite significant.
There are also parallels in biological effects. Thus far, there haven’t been many studies linking wireless radiation to autism; however, there are a number on studies showing the biological abnormalities found in autism that parallel the several studies showing the biological effects of wireless radiation. When you look at the two together the results are striking.
While it would be premature to suggest that wireless radiation is the sole cause of autism, there are compelling correlations that are worthy of inquiry. Hence, I am suggesting that we need more research on this subject –by people with a moral commitment to help our children, a good understanding of bioelectromagnetics, and a good understanding of the physiological dynamics of autism.
I would like to clarify that this article does not intend to offer any vindication for vaccinations. I believe that vaccines and RF create a lethal combination. For some children, like my daughter, toxins in the environment along with high doses of RF were enough to create neurological problems, and I shudder to think what further complications she might have had if she had been vaccinated. In California, when thimerosal was taken out of vaccines statistics showed that autism rates dropped (Geier, 2006) . This was not a surprise to those of us who know the toxic nature of thimerosal . Months later, the autism rates rebounded so they were higher than ever before (Schechter, 2008) . Could this be that the increasing amounts of wireless radiation plus the remaining toxins from vaccines and the environment were the cause of this upsurge? It is a very plausible theory warranting investigation by ethical researchers.
Many of the anecdotal theories make sense when considering the impact of RF on autism. A recent study out of Cambridge University found that autism diagnoses are more common in information technology-rich regions (Baron-Cohen 2011) . Researchers have hypothesized that people who work in technology fields are more likely to carry genetic characteristics of autism and pass those genes on to their children. This is commonly known as the “geek syndrome” theory (Silberman, 2004) . Is it the gene or is it that engineers and computer specialists more likely to be early adopters of wireless technology? Studies have shown that children from affluent school districts are more likely to be diagnosed with autism (Kaiser, 2008) . Is it only due to the quality of the health care and education in those areas or are those families more likely to have high levels of wireless radiation around them? A study out of UC Davis found that if a mother, while pregnant, lives within 309 meters of a freeway, the child is twice as likely to have autism. (Volk, 2010) . Could this have anything to do with the fact that virtually every freeway in America has cell phone towers every few hundred meters? Anecdotes indicate that the Amish are less likely to have autistic children. Is it possible that they are exposed to less wireless radiation than most Americans? Demographic patterns in the use of wireless technology are changing and as wireless technology becomes more ubiquitous these tendencies are naturally likely to change.
With these many possible factors, shouldn’t we be moving into this wireless age with the utmost care and caution? For example, shouldn’t we be seriously considering the worst-case scenarios of having WiFi and other wireless radiation emitting devices in our schools, daycare centers, and homes?
Our children and future generations are counting on us. The more we unravel the puzzle causing this condition, the more we can do to help our children recover and help future generations grow and develop as nature intended.

Is your child's mobile giving them cancer?
Sunday April 22,2012
Have your say(2)
IF you are a parent of the one in three under-10s who now owns a phone, you’ll be aware of the current Department of Health advice: “Children should only use mobile phones for essential purposes and keep all calls short.” If you have not read this advice, possibly because it is tucked away on an obscure website, you might now be wondering how long your child can safely use their phone before their brain turns to mushy peas.
The Government’s view is that parents should take responsibility for whether or not their children have phones in the first place.
Despite the warning about restricting child usage a Department of Health (DoH) spokesman says there is no evidence that mobiles cause tumours but then adds that the scientific evidence is always under review. So what is the scientific evidence?
Next week the charity Children With Cancer is holding a conference in London and one of the subjects it will debate is “brain tumours, mobile phones and childhood cancer”, chaired by Geoffrey Pilkington.
A professor of cellular and molecular neuro-oncology for four decades, he believes that parents should adopt precautions: “If there is any possibility that mobiles can cause tumours, it would suggest children are more vulnerable because their brain cells are still dividing. Anyone who has children wants them to be exposed to risk as little as possible. Therefore until we know more about all possible risks, not only from radiation, parents might want to think carefully about giving children a phone.”
Kevin O’Neill, consultant neurosurgeon at Charing Cross Hospital and chairman of the Brain Tumour Research Campaign, shares Mr Pilkington’s caution.
“There have been many studies looking at the risk of mobile phone use,” says Mr O’Neill. “Some have shown no increased risk and some have shown some increased risk. If the World Health Organisation classifies them as a possible link to the formation of brain tumours, then we need to be cautious about our exposure, particularly if there is a long lag phase between exposure and the production of their health effects.”
Other eminent scientists, such as Emeritus Professor Patricia McKinney at the University of Leeds, are less convinced of the risks. “There is currently little information available on any health risk linked to children’s use of mobiles so to recommend precautionary use can only be sensible,” she says. “My view is that despite some uncertainty, particularly relating to long-term heavy use, accumulating evidence argues against the hypothesis that mobile use causes brain tumours in adults.”

Yes you are right, there is a higher risk of an illness for children because their brains are still developing.
We can also extent this high risk of an illness for teenagers (17 years old) who phone to excess.
It Just Makes Sense – The Link Between mobile phones and the Rise in Autism
Autism is an increasingly common neurological disorder that usually results in abnormal development of social interaction, communication skills and processing of sensory information.
This article is a reply to Masha's complaints about the blue color of the tennis court.
I would like to remember to everybody that colors are also electromagnetic radiations and they have a positive or negative effect on our brain.
For an all-natural brain boost, skip the pills and hit the colors.
In the latest and most authoritative study on color’s cognitive effects, test subjects given attention-demanding tasks did best when primed with the color red. Asked to be creative, they responded best to blue.
"Color enhances performance," said study co-author Juliet Zhu, a University of British Columbia psychologist.
Previous research on red’s effects on the brain have found that it attracts people to food and can enhance sexual arousal. But research on the color’s cognitive effects have been mixed: Studies have linked red to cognitive impairment on IQ tests, telemarketing pitches and analytical problem-solving, but also to improvements on low-demand tasks and clerical work. The latest findings tip the balance toward the red-as-brain-booster results and fits with work that showed a link between the color and arousal of neurobiological awareness and vigilance.
"Think about red, and what comes to mind: stop lights, stop signs, danger, ambulances," said Zhu. "People want to avoid those things, and that’s why they do better on detail-oriented tasks."
While earlier studies tended not to test creativity, Zhu’s findings provide a plausible explanation for blue’s apparent role.
"Blue is the color of the sky, the ocean, safety," she said. "When their environment is safe, people are more explorative."
Zhu’s study, published Thursday in Science, started with tests designed to measure avoidance and attraction. Students vigilantly avoided red and were strongly attracted to blue.
Blue linked to higher scores on subsequent tests of creativity, and red with better performance on memory tests.
State University of New York at Albany psychologist Ronald Friedman, co-author of a study that foundred-linked drops on IQ tests, called the findings "quite remarkable." Stony Brook University psychologist Markus Meier, also a co-author on Friedman’s study, called Zhu’s study "a great paper," one that underscores the unappreciated importance of color.
"Colors are everywhere in our lives," said Meier. "We should use them more carefully in all settings."
To test alternative explanations for the findings, Zhu’s team showed that neither red nor blue influenced mood. Test subjects also spent the same amount of time on their tasks, suggesting that neither color affected their motivation.
The colors appeared to enhance performance, but not to impair it.Red- and white-primed students had similar creativity scores, while blue- and white-primed students were equal on attention tasks.
Asked about the implications, Zhu suggested that people engaged in creative tasks surround themselves with blue, and with red when trying to focus.
"In our university, some professors use different color sheets for different groups during exams," said Meier. "Using them in an unthinking way could produce bad results for some students, and good for others."
Zhu is now studying the effects of red on other types of tasks.
It’s possible, given the other effects provoked by red — interest in food and sex — that it will have different effects in other contexts.
"The science has been focused on the cognitive domain," she said."But maybe in the physical domain, like sports, red can be associated with a different meanings, like power or enthusiasm. That’s what we’re doing now."

Sharapova: Blue clay just about creating buzz Ticker - Saturday, May 5, 2012
Maria Sharapova weighs in on the blue courts in Madrid, as well as her current goals.
"We’ve played on red clay for so many years," she told reporters. "I find [the blue clay] different and some parts of court have more clay than others. They are trying to work the kinks out. There are so many things we players have to adjust to, and there are not a lot of things that are consistent. I’d like to see more consistency. I think [the blue clay] is a little more for spectators, TV and more for buzz than anything else. I think it’s more for show than for the players."
The world No. 2 also told Medio Tiempo that world No. 1 Victoria Azarenka has become her biggest rival (Sharapova upended the Belarussian in last week's Stuttgart final after losing to her in the Australian and Miamifinals) and discussed both winning her fourth major and returning to the top of the rankings.
"Fortunately I had the opportunity to see how it feels before in those two situations," she said. "I would be very happy if I won more Grand Slams and became No. 1 again and now that I'm close to having that possibility, it’s one of my goals this year, but mostly it’s to play like a true No. 1."
Belo Horizonte is the third largest city in Brazil. In 2011, a 10 year study on cell phone antennas was released by the Municipal Health Department and several local universities. The study found a greater risk for cancer if you lived within 500 meters of a cell phone antenna or tower. Shortly after this study was published, the city prosecutor sued several cell phone companies and requested almost half of the cities antenna to be removed. In this video you will see the details of the investigation.To view the study abstract, charts and graphs of the publication, the link is provided below. http://www.sciencedirect...le/pii/S0048969711005754To view a related video about this study and others regarding the health effects of cell towers visit - http://youtu.be/AEOcB7Svhvw
WASHINGTON, November 2 (RIA Novosti) - With cell phone service knocked out and no electricity in many parts of New York City in the wake of Hurricane Sandy, people are waiting in lines to use a relic from the past – the pay phone.
“I didn’t even know they were working,” New York City resident Leslie Koch said about the public pay phones in an interview with the Wall Street Journal.
Earlier this week Koch celebrated her blast with the past when she used the antiquated device by taking a picture of it and posting it to her Twitter account with a caption that said, “This is called a pay phone. Used one today to call my mom from #NYC.”
Koch is one of many New Yorkers who had been walking past pay phones on a daily basis and didn’t pay them any attention.
“It’s funny what’s hiding in plain sight,” Jordan Spak, a 32-year-old television marketer told the Journal. “It’s invisible, but when you need it, it’s there.”
In the storm’s aftermath, throngs of residents are using the old-fashioned contraptions as a last resort to connect to family and friends, because millions of people lost power during the storm rendering their cellphones, iPads, computers and other state-of-the-art technology useless.
Alison Caporimo, 24, who lives in Manhattan, told the Journal she didn’t even know how to operate a public pay phone before Tuesday admitting, “I lost a lot of coins” while trying to figure out how to use the outdated machine.
Although many New Yorkers are dependent on modern gadgetry, during times of distress, such as after the September 11 terrorist attacks, the city has become reliant on pay phones that usually stay in service even during flooding. In fact, one of the most daunting challenges with using the devices during an emergency is keeping them free of coin overloads, the Journal reported.
“During disasters, we sometimes have to empty them every day,” Thomas Keane, chief executive officer of Pacific Telemanagement Services, said. “It takes 300 to 400 calls a day for that to happen.”
The dependency on the retro technology this week comes just months after New York announced a pilot program to convert several pay phones around the city into free WiFi hotspots.
There are about 12,000 public pay phones in New York City, 27,000 fewer than 20 years ago, according to the Department of Information Technology and Telecommunications, which regulates the city’s pay phones.
Congo is the world’s third largest producer of tantalum used in high-tech electronics. Even a temporary supply shortage may deal a serious blow to the electronics industry with far-reaching consequences for other branches. The situation in Congo is just one example of how regional conflicts may affect the lives of millions of people on other continents.
Although sparked by a tribal and clan feud, the ongoing bloodshed in that central-African country is actually a war for mineral resources. This week, the rebels seized Goma, the biggest city in the mineral-reach eastern part of Congo, and are poised to fight on with government troops and UN forces unable, so far, to check their advance. The rebels, who call themselves the March 23 Movement, or M23, are widely believed to enjoy clandestine support from neighboring Rwanda and Uganda struggling for access to Congo’s mineral wealth.
Congo has vast and largely untapped reserves of oil, gold, diamonds, copper, uranium, cobalt and other minerals, including tantalum – a rare-earth metal used in the nuclear power industry, mobile phones, computers, digital cameras and other high-tech products. With demand for tantalum growing faster than supply, fueled by rapidly-developing high-tech branches, tantalum is becoming more profitable than gold or diamonds. For Congo’s poor neighbors, control over tantalum deposits could mean a chance for an economic breakthrough and higher living standards. And although producers have stockpiled sufficient quantities of tantalum, the situation is very alarming and prompting scientists to look for alternatives.
Analysts draw parallels with Serbia and the Balkan conflict. A Western project for the independence of Kosovo intended not only to punish the disobedient Serbia, but also to strip it of a vast portion of mineral reserves – coal, gold, platinum, bauxites, zinc, nickel and cobalt – estimated at dozens of millions of tons. Cobalt, for example, is a key element in renewable energy production.
The recent bloody war in Sudan is seen by some experts as a battlefield between Beijing and Washington. China has invested and continues to invest billions of dollars in Africa and made it a priority of its foreign policy. As a result of the war, Sudan split into two separate states – Sudan and South Sudan. Last year, the oil-rich South Sudan acquired independence with the active assistance of the United States. But the Sudanese oil, though extracted in the south, cannot be transported other than through the north, which makes oil transit an essential issue with many lances broken over it already.
As the global population grows at a rate of tens of millions per year, the task of providing it with energy and staple goods is becoming a top priority. While for many countries, control over mineral resources is actually a matter of surviving, for elites it’s an opportunity to enrich themselves uncontrollably. Wars for resources may assume epidemic proportions.
