mierhln.be / demorgen.be - Een onderzoek van de ULB toont aan dat gsm-stralen een schadelijk effect hebben op mieren en eencellige micro-organismen die vaak bij wetenschappelijk onderzoek gebruikt worden. De ULB meldt in een persbericht dat het onderzoek een primeur is voor België. "Als gsm-stralen schadelijk zijn voor eencelligen, geldt dat voor iedereen", aldus Marie-Claire Cammaerts van de vakgroep Biologie van organismen. Alle functies die een celmembraan nodig hebben worden aangetast, het zenuwstelstel in de eerste plaats."

 

Gsm-stralen tasten het celmembraan van de eencelligen aan en verzwakken hun geheugen. Mieren zouden door gsm-stralen trager op feromonen reageren. De onderzoekers stelden eencelligen en mieren bloot aan een golvengenerator, "in omstandigheden vergelijkbaar aan golven geproduceerd door die van een gsm of een antenne", verduidelijkte Cammaerts.

 

Tijdens verschillende experimenten stelden de onderzoekers vast dat de reukzin en het zicht van mieren aangetast werden. Zo konden ze, nadat ze voedsel gevonden hadden, de weg naar het nest niet meer terugvinden. De mieren bewogen zich moeilijk voort, aten een beetje en stierven vervolgens. Voor eencelligen waren de resultaten gelijkaardig. In de nabijheid van gsm's verplaatsen ze zich moeilijk en zwellen ze op. Dat kan, volgens de studie, verklaard worden door schade aan het celmembraan.

Electromagnetic fields and health: DNA-based dosimetry


We propose a biologically based measure of EMF radiation to replace the energy-based “specific absorption rate” (SAR). A wide range of EMF frequencies has been linked to an increased risk of cancer. The SAR value used to measure the EMF dose and set the safety standard in the radiofrequency (RF) range fails as a standard for predicting cancer risk in the ELF power frequency range. Because cancers are believed to arise from mutations in DNA, changes in DNA induced by interaction with EMF could be a better measure of the biologically effective dose in both frequency ranges. The changes can be measured by transcriptional alterations and/or translational changes in specific proteins. Because ionizing radiation also causes DNA damage, a biologically based standard related to stimulation of DNA could apply over a much wider range of the electromagnetic spectrum. A safety standard for exposure to a wide range of non ionizing frequencies can be based on the documented changes in DNA biochemistry that arise from interactions with EMF.

Overlijden pionier stralingsonderzoek die schadelijke effecten op het oog documenteerde

Blueyemicrowavenews.com - Milton Zaret, een (Amerikaanse) pionier in het stralingsonderzoek is vorige maand op 91-jarige leeftijd gestorven. Hij was een van de eerste wetenschappers die in de jaren '70 waarschuwde voor de schadelijke gezondheidseffecten van microgolfstraling. Zijn eigen onderzoek, dat hij uitvoerde in opdracht van het Amerikaanse leger, bracht aan het licht dat hoogfrequente straling diepgaande effecten heeft op het menselijk oog en het risico op cataract verhoogt. Dit risico verhoogt niet enkel door acute, hoge blootstellingen, maar ook door langdurige, zwakkere blootstellingen.

 

In 1973 bracht de onderzoeker deze boodschap in het Amerikaans parlement:

 

"There is a clear, present and ever-increasing danger to the entire population of our country from exposure to the entire non-ionizing portion of the electromagnetic spectrum. The dangers cannot be overstated because most non-ionizing radiation injuries occur covertly, usually do not become manifest until after latent periods of years, and when they do become manifest, the effects are seldom recognized."

"75% of the peer-reviewed published scientific studies report biological changes"

Powerwatch.org.uk - In our opinion, the Institution of Engineering and Technology has issued another well spun and misleading press release stating that "there is no persuasive evidence that normal mobile phone use or adult exposure to pylons and powerlines causes harmful effects such as cancer". Its Biological Effects Policy Advisory Group (BEPAG) says that "the overwhelming majority of the evidence does not indicate that normal exposure to low-level electromagnetic fields has harmful health effects".

 

However, if you read their full Statement, it reports: "The searches revealed 726 relevant papers in 2010 and 2011 combined, 11% lower than in 2009/2010." ... "An analysis of those papers which contain new experimental data shows that, at electrical power frequencies (50 or 60 Hz), 80% (previously 81%) of the 113 papers report biological effects, whereas at mobile phone frequencies the figure is rather lower, 59% (previously 54%) of 170 papers.... Overall 75% of experimental studies report the detection of field effects, unchanged from 2009/2010." So, in fact, 75% of the peer-reviewed published scientific studies continue to report biological changes following EMF/RF exposure.

 

BEPAG apparently can't map these onto health effects so they effectively dismiss them and say to the public "carry on as usual, please don't worry your little heads about such matters". They justify this by saying that most studies cannot be replicated. Whilst replication is important, the very fact that, over many years, far more papers are reporting biological effects than not reporting biological effects, actually makes quite a strong case that long-term health effects may result from these exposures.

Microwavenews.com - Last night, we came across an item from five years ago under the title "Cell Specific Responses to RF." It highlighted some new research from Finland, which found that cell phone radiation affected the activity of ODC, a biologically important enzyme, in primary, but not secondary, cell lines.


Primary cells are those taken from a live animal while secondary lines, or cultured cells, tend to be bought from a supplier. As the Finnish researchers pointed out, primary lines act more like cells in a live animal. That said, most people use cultured cells because they mulitply in the lab and are more likely to be uniform, and, perhaps most important, they are much easier to get.

 

At the time, we called the results "startling" because they could help explain why so much of cell biology on RF radiation is contradictory and hard to interpret.

Harvard Law School - On Nov. 3, Dr. Franz Adlkofer, former executive director of the VERUM Foundation for Behavior and Environment, spoke to a Harvard Law School audience as part of the lectures and events series hosted by the Edmond J. Safra Center for Ethics.

 

In his lecture, "Protection Against Radiation is in Conflict with Science," Adlkofer discussed the difficulties he and other scientists face when presenting research on the carcinogenic effects of electromagnetic fields emanating from cell phones. He also discussed the institutional corruption which he says obstructs their research.

Decision makers need access to the best available science in order to craft policies that protect our health, safety, and environment. Unfortunately, censorship of scientists and the manipulation, distortion, and suppression of scientific information have threatened federal science in recent years.

 

This problem has sparked much debate, but few have identified the key driver of political interference in federal science: the inappropriate influence of companies with a financial stake in the outcome.

 

A new UCS report, Heads They Win, Tails We Lose, shows how corporations influence the use of science in federal decision making to serve their own interests.

Zwangere_buik_gsmNature - Neurobehavioral disorders are increasingly prevalent in children, however their etiology is not well understood. An association between prenatal cellular telephone use and hyperactivity in children has been postulated, yet the direct effects of radiofrequency radiation exposure on neurodevelopment remain unknown.

 

Here we used a mouse model to demonstrate that in-utero radiofrequency exposure from cellular telephones does affect adult behavior. Mice exposed in-utero were hyperactive and had impaired memory as determined using the object recognition, light/dark box and step-down assays. Whole cell patch clamp recordings of miniature excitatory postsynaptic currents (mEPSCs) revealed that these behavioral changes were due to altered neuronal developmental programming. 

 

We present the first experimental evidence of neuropathology due to in-utero cellular telephone radiation.

Bericht International EMF Alliance - Greek Study Shows Regions of the Brain Related to Learning, Memory, Alzheimer's Impacted by EMF

 

A Greek study led by Adamantia Fragopoulou and Lukas Margaritis has demonstrated important protein changes in the brain of animals following whole body exposure to RF electromagnetic fields, similar to the kind of microwave radiation emitted from cell phones, portable phones, WiFi and wireless computer equipment. The study, was published in Electromagnetic Biology and Medicine, Early Online: 1-25, 2012.

 

Important regions of the brain necessary for learning, memory and other functions of the mammalian brain were impacted by the microwave radiation, including the hippocampus, cerebellum and frontal lobe, at exposures below the ICNIRP (International Commission on Non-Ionizing Radiation Protection) safety guidelines. A total of 143 proteins in the brain were impacted by the RF radiation over a period of 8 months, providing new evidence for a potential relationship between everyday cell phone use, wireless transmitters and wireless computer equipment and electrosensitivity symptoms, such as headaches, dizziness and sleep disorders, as well as with tumors, Alzheimer's and even metabolic effects.
