Squashing the Cheshire Cat

 

microwavenews.com - Lucas Portelli just ran over the Cheshire cat. He didn't know it was there. He's too young to appreciate how this fictional feline has held sway in the EMF-health controversy.

 

In a systematic measurement survey, Portelli has shown that the ambient static and time-varying magnetic fields in laboratory incubators are large and variable: He found that they can differ by a factor of a hundred or even a thousand within and between incubators.

 

"These variations can be observed within the same incubator in locations that are centimeters apart," he writes in a paper published in Bioelectromagnetics earlier this month. Such magnetic fields could be a "potential confounder" of cell culture studies, he warns.

Scientific Peer Review in Crisis - The case of the Danish Cohort, gepubliceerd in The Scientist

 

The publication of a scientific study in a peer-reviewed journal is commonly recognized as a kind of "nobilitation" of the study that confirms its worth. The peer-review process was designed to assure the validity and quality of science that seeks publication. This is not always the case. If and when peer review fails, sloppy science gets published.

Five of the Top EMF Scandals of 2011

Gepubliceerd: donderdag 21 februari 2013 08:48

 

Electromagnetic Bioeffects Blog - A recent article in The Scientist: Magazine of the Life Sciences listed the top five science scandals of 2011 (science scandals). (...) These five obscure instances are what a big-time science journal considered the premier ethical lapses in science during 2011. But these cases of fraud, falsification, and plagiarism, if that’s what they were, probably affected only a few hundred people at most—the rest of the ten billion people on earth were unaffected. For this reason, the magazine article seriously trivialized the concept of ethical misconduct in science. Meaningful misconduct hurts people, and a scientist should hurt a lot of people to qualify for a top-five ranking. By this standard, my candidates for the top five science scandals of 2011 involved publications by Leeka Kheifets, James Rubin, Michael Repacholi, Joe Elder, and Mays Swicord. Articles they published in 2011, which were continuations of their life work, directly and materially contributed to the occurrence of cancer and other dreadful diseases in many million men, women, and children.

Persbericht: BioInitiative 2012 Report Issues New Warnings on Wireless and EMF

www.bioinitiative.org

''A new report by the BioInitiative Working Group 2012 says that evidence for risks to health has substantially increased since 2007 from electromagnetic fields and wireless technologies (radiofrequency radiation). The Report reviews over 1800 new scientific studies. Cell phone users, parents-to-be, young children and pregnant women are at particular risk.

“There is a consistent pattern of increased risk for glioma (a malignant brain tumor) and acoustic neuroma with use of mobile and cordless phones” says Lennart Hardell, MD at Orebro University, Sweden. “Epidemiological evidence shows that radiofrequency should be classified as a human carcinogen. The existing FCC/IEE and ICNIRP public safety limits and reference levels are not adequate to protect public health.”

Mobile Phone Turns Enzyme Solution into A Gel

A highly reproducible non-thermal effect of mobile phones depends on interaction between protein and water. Dit e-mailadres wordt beveiligd tegen spambots. JavaScript dient ingeschakeld te zijn om het te bekijken. says it brings us closing to understanding the biophysics involved in how weak electromagnetic radiation can have biological effects.

Serious brain damage unaccounted for

 

The most striking effect of exposure to the radio-frequency (RF) radiation from mobile phones is damage to the brain and brain cells of rats (see "Mobile phones & brain damage" SiS24), which were found at levels of exposure far below the current safety limits. After just two hours of such exposure, blood albumin leaked into the brain causing brain cells to die; and the effects lasted for at least 50 days after a single exposure. But no clear mechanism has emerged to explain this or other ‘non-thermal’ effects of electromagnetic fields (EMFs) even after a concerted, Europe-wide research programme (see "Confirmed: mobile phones break DNA and scramble genomes", this series).

Bron: Biomedical and Environmental Sciences. 2012 Apr. 25 (2):182-8.

Relationship between cognition function and hippocampus structure after long-term microwave exposure.

 

RESULTS: Following long-term microwave exposure there was a significant decrease in learning and memory activity in the 7 d, 14 d, and 1 m in all three microwave exposure groups. Neurotransmitter concentrations of four amino acids (glutamate, aspartic acid, glycine, and gamma-aminobutyric acid) in hippocampus were increased in the 2.5 and 5 mW/cm2 groups and decreased in the 10 mW/cm2 group. There was evidence of neuronal degeneration and enlarged perivascular spaces in the hippocampus in the microwave exposure groups. Further, mitochondria became swollen and cristae were disordered. The rough endoplasmic reticulum exhibited sacculated distension and there was a decrease in the quantity of synaptic vesicles.

CONCLUSION: These data suggest that the hippocampus can be injured by long-term microwave exposure, which might result in impairment of cognitive function due to neurotransmitter disruption.

Interview over bioelektriciteit met professor aan Oxford University

British Scientist Driven To Find 'Spark Of Life'

Beluister het interview hier.

npr.org - One night in 1984, British scientist Frances Ashcroft was studying electricity in the body and discovered the protein that causes neonatal diabetes. She says she felt so "over the moon" that she couldn't sleep.

 

By the next morning, she says, she thought it was a mistake.

But luckily, that feeling was wrong, and Ashcroft's revelation led to a medical breakthrough decades later, which now enables people born with diabetes to take pills instead of injecting insulin.

 

"I don't think people realize the excitement of being a true discoverer," Ashcroft tells Fresh Air's Terry Gross. "There are no new places to discover on this Earth, but there are many, many new ideas to discover — new things to find out about the way the world works."

 

Ashcroft says she grew up wanting to be a farmer's wife but later became fascinated with studying electrical impulses in the body. Her new book The Spark of Life details how electricity drives everything we think, feel or do through ion channels that are found in the membranes of each of our cells.

 

"Your ability to hear me now is because there are cells in your ears that are converting sound waves into an electrical signal, which is what the brain can interpret as sound," Ashcroft says.

Ashcroft is a professor at Oxford University and the winner of the L'oreal-UNESCO Award for Women in Science. She is now working on trying to see a particular protein at atomic resolution and on understanding why people become overweight.

McGill University Professor Proposes Radical New Outlook


September 27, 2012, microwavenews.com

 

Paul Héroux has a problem. He believes he has identified a way to control the growth of cancer cells, but he can't get his ideas into print. "We think we have the Rosetta Stone that will allow us to unravel the intricacies of cancer physiology," says Héroux, a professor at McGill University in Montreal. Yet, one scientific journal after another has refused to publish what he has found.

 

Part of Héroux's problem is that his argument is based on an even more controversial proposition than a possible cure for cancer: That extremely weak magnetic fields can bring about major changes in DNA. That is a tough sell. Héroux ups the ante another notch by claiming to show that those changes are so easy to spot that you don't need hi-tech instruments to see them, just a standard issue microscope. All you have to do is count chromosomes, admittedly with close attention to detail.

And that's not all. Héroux says he has pinpointed where and how the magnetic field acts on the cell.

 

Héroux is in McGill's Department of Epidemiology, Biostatistics and Occupational Health and runs the InVitroPlus Lab at the Royal Victoria Hospital in Montreal.

Gepubliceerd: maandag 03 september 2012 10:08

 

More and more evidence from over 50 years of researches on the effects of electromagnetic radiation on male reproduction show that a certain dose of electromagnetic radiation obviously damages male reproduction, particularly the structure and function of spermatogenic cells. The mechanisms of the injury may be associated with energy dysmetabolism, lipid peroxidation, abnormal expressions of apoptosis-related genes and proteins, and DNA damage.
