Chinese researchers exposed pregnant rats to cell phone radiation and reported significant neurological differences in fetal brains, concluding a certain dose causes harm. Earlier work tied handset use two or three times a day in pregnancy to more hyperactivity and conduct problems at school age.

Cell phone radiation linked to brain cancer - study confirms
Cardis and colleagues report in Occupational and Environmental Medicine that regular cell phone users were 7% more likely to be diagnosed with glioma and 20% more likely with meningioma, and that the most heavily exposed group was 35% more likely to develop glioma.

New studies link cell phones to brain cancer?
Analysing Interphone data from 13 countries, the study found the heaviest mobile phone users, at 1,640 hours or more, had 40 percent higher glioma risk and 15 percent higher meningioma risk, while the second-heaviest users showed lower risk, which the authors attribute to bias.

Do Cell Phones Cause Brain Cancer?
In 1993 David Reynard argued on Larry King's show that cell phone radiation caused his wife's brain tumor, and a Florida court rejected the case as premature. The New York Times revisits what is known nineteen years on, noting cancer may take 50 to 70 years to develop.

Caution: This Common Device Can Double Your Risk of Getting a Brain Tumor
Dr. Martin Blank of Columbia University, speaking at a November 2010 Commonwealth Club program, explains how electromagnetic fields from cell phones and other wireless devices act on cells, and why DNA is especially vulnerable compared with other tissues.

Use this Common Device and Double Your Risk of Brain Cancer…
Mercola summarises Devra Davis's book Disconnect, which gathers studies suggesting cell phone radio-frequency radiation can damage DNA and may contribute to brain tumours in heavy young users, and argues many reassuring studies were industry funded.
Environment
City Passes First Cell Phone Radiation Law
San Francisco became the first US city to make retailers post each phone's specific absorption rate beside it in at least 11-point type. SAR values were already in manuals and FCC databases; the law makes them easy to compare. Mercola welcomes the change.
Environment
Cell phone use may increase brain cancer risk
A study in the International Journal of Epidemiology found people using cell phones 30 or more minutes a day were 40 percent more likely than the lightest users to develop glioma. News reports called the findings inconclusive, and researchers note brain tumors can take decades to appear.
Environment
New Law May Slow Cell Phone Cancer Epidemic
A Maine bill, HP 1207/LD 1706, would make the state the first to require labels warning that cell phones can cause brain cancer, especially in children. One supporter compares waiting to the delay over smoking; the wireless industry calls the bill grandstanding.

Cell Phone Usage May Reduce Alzheimer's Risk
University of South Florida researchers exposed 96 mice, some bred to develop Alzheimer's, to cell-phone-level radiation two hours a day for seven to nine months. Mice not yet impaired were protected, older symptomatic mice improved, and even normal mice showed better memory.

Make free cell phone calls through Magic Jack
A $40 Magic Jack due within four months would let users place calls from a cell phone without paying the carrier, routing them over a home broadband connection rather than the wireless network. It works with AT&T and T-Mobile GSM handsets, not Verizon or Sprint. The maker says the device is legal.

Cell phone radiation may hurt memory - study
A University of South Florida mouse study found cell phone radiation warded off and even reversed Alzheimer's-like disease, and a Danish study linked phone use to fewer dementia hospital contacts in men. A Greek mouse study found impaired spatial learning after four days of exposure.
Lifestyle
Could cell phones cure Alzheimer's disease?
University of South Florida researchers exposed mice to cell phone radiation twice a day for seven to nine months and report Alzheimer's-prone mice avoided the disease while affected mice improved. A Danish cohort found fewer dementia hospital contacts among male cell phone users.
Lifestyle
Cell phone radiation may prevent or even cure Alzheimer's disease
University of South Florida researchers exposed 96 mice, some bred to develop Alzheimer's-like disease, to cell phone radiation. Treated mice matched normal aged mice on cognitive tests, memory loss reversed in older Alzheimer's mice, and the waves erased beta-amyloid deposits.

A Cell Phone on Your Hip Weakens Your Bones
Researchers measured pelvic bone density in 150 men who carried cell phones on their belts an average of 15 hours a day for about six years, and found lower bone mineral density on the side where the phone sat, raising the possibility that electromagnetic fields affect bone.

WHO will admit cell phones raise brain cancer risk*
London's Daily Telegraph reported the WHO will announce that long-term cell phone use may be linked to elevated risk of some brain cancers, from a 13-country study of 12,800 people that remains inconclusive. A recent meta-analysis of 23 studies found no connection overall.

Secret Link Between Cigarettes and Cell Phones?
A review of 11 long-term epidemiologic studies found that using a cell phone for 10 or more years roughly doubles the risk of a brain tumor on the side of the head the phone is held against. Senator Tom Harkin has promised to investigate any link to cancer.

EWG offers tips on how to reduce cell phone radiation
The Environmental Working Group's eight tips for cutting cell phone radiation: pick a low-emission model, use a headset or speaker, hold the phone away from your body, text rather than talk, avoid calls on weak signals, keep phones from children, and skip radiation shields.
