Toomuch Use of Cell Phone May Cause Brain Cancer


An epidemiologist and toxicologist who is an expert in environmental health has found evidence linking cell phone usage to an increased rate of certain kinds of brain tumors in young people who were heavy cell phone users.


In her book, Disconnect, Dr. Devra Davis talks about how she found evidence of studies, some decades old, showing that the radio-frequency radiation used by cell phones could have biological effects — enough to damage DNA and potentially contribute to brain tumors.

As reported by Time, Davis also found that many of the studies debunking a link between cell phone usage and adverse events were mostly funded by the industry. According to Time:

“She found that other countries—like France and Israel—had already acted, discouraging the use of cell phones by children and even putting warning signs on handsets. …

“This is about the most important and unrecognized public health issues of our time,” says Davis. “We could avert a global catastrophe if we act.”

“Davis also said that industry resistance would make regulation “harder and harder,” but that the good news is “simply using a wired headset should significantly cut down on radiation exposure to the brain, although Davis recommends that children—whose thinner skulls can absorb higher levels of radiation—avoid using phones altogether.”

Women’s Natural Scent More Seductive Than Perfume

Women might want to think twice before spritzing Chanel No. 5. A new study suggests that a woman’s natural scent may be all she needs.

…………
Recent research shows that a man’s testosterone levels, which are linked with sexual interest, are significantly higher when they smell the shirt of a woman who is ovulating.

Other studies have linked higher levels of testosterone with an increase in sexual arousal as well.

In surveys, men have reported being more attracted to ovulating women. The new study builds on this research by measuring the response of men to a specific chemical cue

Cell Phone on Hip May Weakens Your Bones

Research suggests that wearing a cell phone on your hip may weaken an area of your pelvis. Using an X-ray technique used in the diagnosis and monitoring of patients with osteoporosis, researchers measured pelvic bone density in 150 men who regularly carried their cell phones attached to their belts.

The men carried their phones for an average of 15 hours each day; they had used cell phones for an average of six years.

The researchers found that bone mineral density was lowered on the side of the pelvis where the mobile phones were carried. The findings raise the possibility that bone density could be adversely affected by electromagnetic fields emitted by cell phones.

Are Nano-Foods the Next Scary Items?

Those consumers already worried about genetically engineered or cloned food reaching their tables may soon find something else in their grocery carts to furrow their brows over – nano-foods.

..

Consumer advocates taking part in a food safety conference in Orlando, Florida, this week said food produced by using nanotechnology is quietly coming onto the market, and they want US authorities to force manufacturers to identify them.

Nanotechnology involves the design and manipulation of materials on molecular scales, smaller than the width of a human hair and invisible to the naked eye. Companies using nanotechnology say it can enhance the flavor or nutritional effectiveness of food.
US health officials generally prefer not to place warning labels on products unless there are clear reasons for caution or concern. But consumer advocates say uncertainty over health consequences alone is sufficient cause to justify identifying nano-foods.

“I think nanotechnology is the new genetic engineering. People just don’t know what’s going on, and it’s moving so fast,”Jane Kolodinsky, a consumer economist at the University of Vermont, said at the conference.

American consumers are generally more complacent about genetically modified or cloned foods than their counterparts in Europe. But Michael Hansen, a senior scientist with the Consumers Union, said polls show that 69% of Americans are concerned about eating cloned meat.

He said that in focus groups run by the US Food and Drug Administration, no parents were willing to feed their children meat from cloned animals or their offspring.

New consumer products created through nanotechnology are coming on the market at the rate of 3 to 4 per week, according to an advocacy group, The Project on Emerging Nanotechnologies (PEN), based on an inventory it has drawn up of 609 known or claimed nano-products.

Nano-products in common use today include lightweight tennis rackets and bicycles, and sunscreens containing clear, nonwhite versions of zinc oxide and titanium dioxide. On PEN’s list are three foods – a brand of canola cooking oil called Canola Active Oil, a tea called Nanotea and a chocolate diet shake called Nanoceuticals Slim Shake Chocolate.
