”Still worried about power lines and cancer? That’s so retro, says the New York Times. You’re just stuck in the 1980’s.  

This is what the “newspaper of record” wants you to know about the risk of childhood leukemia from power lines: A “fairly broad consensus among researchers holds that no significant threat to public health has materialized.”

The full message is told in a new 7+ minute video, produced by the Times’ RetroReport, which boasts a staff of 13 journalists and 10 contributors, led by Kyra Darnton. The video even credits a fact checker. What was missing is the common sense to do some digging when reporting on a controversial issue.

Power-frequency magnetic fields can promote brain tumors, according to the largest epidemiological study of its kind ever undertaken. The study promises to breathe new life into the idea that extremely low frequency (ELF) EMFs are more likely to be cancer promoters than causes of cancer. This hypothesis gained support a generation ago but has lost currency in recent years.

The new results, published online earlier this month by the journal Cancer Epidemiology, Biomarkers & Prevention, come from INTEROCC, an international project with seven participating countries designed to investigate occupational health risks from chemicals and EMFs. The project is directed by Elisabeth Cardis at CREAL in Barcelona with $1.5 million from the U.S. National Institutes of Health (though none of the tumor cases are from the U.S.).

The INTEROCC team found that those who were exposed to elevated EMF exposures at work during the five years prior to diagnosis had significantly higher rates of glioma compared to those who were least exposed during that time on the job. The greater the exposure, the greater the tumor risk.

De-Kun Li is the last man standing. Not long ago, many of the leading environmental epidemiologists in the U.S. were working on EMFs of one kind or another. They've all moved on —all except De-Kun Li, and he continues to break new ground in one study after another.

Li, a senior researcher at Kaiser Permanente in Oakland, CA, has now shown that EMF exposures in the womb are linked to an increased risk of childhood obesity.

"Maternal exposure to high [magnetic fields] during pregnancy may be a new and previously unknown factor contributing to the world-wide epidemic of childhood obesity/overweight," Li writes in a paper posted today by Scientific Reports, a peer-reviewed, open access journal owned by the group that publishes Nature.

It's not easy to reach unanimous agreement on anything to do with cell phone radiation. And when it comes to cell phones and cancer, forget about it. But the International Agency for Research on Cancer (IARC) nearly pulled it off. On Tuesday, May 31, more than two dozen scientists and doctors from 14 countries —a group IARC Director Christopher Wild called “the world’s leading experts”— issued a joint statement that cell phone and other types of radiofrequency (RF) and microwave radiation might cause cancer.

Editors and reviewers at Epidemiology thought long and hard before publishing the new paper suggesting that a child's behavioral problems can be traced, at least in part, to the mother's use of a cell phone use during pregnancy (see our May 14 post). This comes across in an editorial by David Savitz that appears the same issue (July) as the paper.

The study is "a nearly perfect recipe for 'inflammatory epidemiology'," acknowledged Savitz, an editor at the journal who has long been involved with EMF research. But, he went on, "reviewers and editors believe that these findings are worth consideration by the scientific community.

Mobile phones may present a cancer risk after all. Epidemiologists at the Karolinska Institute in Stockholm have found that the phones can increase the incidence of acoustic neuromas, benign tumors of the auditory nerve. The nerve is exposed to radiation during the normal use of a cell phone.

Those who used mobile phones for at least ten years, had close to twice the risk of developing acoustic neuromas, according to a team led by Dr. Maria Feychting and Prof. Anders Ahlbom of the Karolinska’s Institute of Environmental Medicine. Ahlbom is the deputy director of institute.
