Effects of two different waveforms of ELF MFs on bioelectrical activity of antennal lobe neurons of Morimus funereus (Insecta, Coleoptera).

Todorović D, Prolić Z, Petković B, Kalauzi A. · 2015

Researchers exposed longhorn beetles to 50 Hz magnetic fields (the same frequency as power lines) and measured how their brain neurons responded. They found that square wave magnetic fields caused measurable changes in neural activity after 10-15 minutes of exposure, while sine wave fields did not. This demonstrates that even insects show biological responses to power-frequency magnetic fields, and that the waveform shape matters for biological effects.

Does the Brain Detect 3G Mobile Phone Radiation Peaks? An Explorative In-Depth Analysis of an Experimental Study.

Roggeveen S, van Os J, Lousberg R · 2015

Researchers investigated whether third generation mobile phone radiation peaks produce event-related potentials in the brain. Thirty-one healthy females took part in a single-blind, cross-over design where a 15 minute mobile phone exposure was compared to two 15 minute sham phone conditions. When the phone was placed at the ear, an enlarged cortical reactivity was found in the frontal and central cortical regions, but not when it was placed at the heart.

Inter‐individual and intra‐individual variation of the effects of pulsed RF EMF exposure on the human sleep EEG

Lustenberger et al. · 2015

The study investigated how much variation exists between individuals and within the same individual in response to pulsed radiofrequency electromagnetic field exposure during sleep. The EEG analysis showed exposure-related increases in the delta-theta frequency range at several fronto-central electrodes, but no differences in the spindle frequency range. Reproducible within-subject effects on sleep spindle and delta-theta activity were not observed, and it remained unclear whether a biological trait of how subjects' brains react to RF EMF exists.

Radiofrequency signal affects alpha band in resting electroencephalogram

Ghosn R et al. · 2015

Researchers recorded resting EEG in 26 healthy young subjects under sham and real RF exposure conditions in a double-blind, counterbalanced, crossover design. Compared with the sham session, the exposure session showed a statistically significant decrease of alpha band spectral power during the closed-eyes condition. This effect persisted in the postexposure session, and no significant changes were detected in electrode impedance, salivary cortisol, or caffeine between conditions.

Effects of extremely low frequency electromagnetic fields on human fetal scleral fibroblasts

Unknown authors · 2014

Researchers exposed human fetal eye tissue cells to 50 Hz electromagnetic fields (the same frequency as power lines) at various intensities for up to 48 hours. The EMF exposure significantly reduced cell growth rates and disrupted the production of collagen, the protein that gives structure to eye tissue. These changes could potentially affect normal eye development.

Is magnetite a universal memory molecule?

Unknown authors · 2014

Norwegian researchers propose that magnetite (iron oxide crystals) found naturally in human brains, hearts, livers and spleens may function as a universal memory storage system for all living cells. The hypothesis suggests that because magnetite concentrations are disrupted in Alzheimer's disease and iron imbalances affect memory, these magnetic crystals could be how our bodies store and retrieve information at the quantum level.

Self-reporting of symptom development from exposure to radiofrequency fields of wireless smart meters in victoria, australia: a case series

Unknown authors · 2014

This Australian case series examined 92 Victoria residents who reported health symptoms after smart meters were installed in their homes. The most common symptoms were insomnia, headaches, tinnitus, fatigue, cognitive problems, abnormal sensations, and dizziness. Notably, most participants had never experienced electromagnetic hypersensitivity before smart meter exposure.

Residential proximity to electromagnetic field sources and birth weight: Minimizing residual confounding using multiple imputation and propensity score matching

Unknown authors · 2014

Researchers studied 140,356 births in Northwest England to examine whether living near power lines affects baby birth weight. They found that mothers living within 50 meters of electromagnetic field sources had babies weighing 116 grams less on average. This study used advanced statistical methods to minimize confounding factors and confirm the association between proximity to power infrastructure and reduced fetal growth.

Occupational exposure to extremely low-frequency magnetic fields and brain tumor risks in the INTEROCC study

Turner MC et al · 2014

Researchers studied over 9,000 people across seven countries to examine whether occupational exposure to extremely low-frequency magnetic fields (like those from power lines and electrical equipment) increases brain tumor risk. They found that workers with high ELF exposure in the 1-4 years before diagnosis had a 67% higher risk of glioma brain tumors. This suggests ELF fields may promote existing tumor growth rather than initiate new tumors.

Characterization of Indoor Extremely Low Frequency and Low Frequency Electromagnetic Fields in the INMA- Granada Cohort

Calvente I et al · 2014

Spanish researchers measured extremely low frequency electromagnetic fields (15 Hz to 100 kHz) in 123 homes of 9-10 year old children, finding exposure levels below international safety guidelines but with significant variation between homes. Urban homes showed higher EMF levels than rural ones, and magnetic fields were 1.6 times higher during daytime versus nighttime. The study concluded that preventive measures are warranted to reduce children's exposure given their greater sensitivity to EMF.

Dosimetric study of fetal exposure to uniform magnetic fields at 50 Hz

Liorni I et al · 2014

Italian researchers used computer models to calculate how 50 Hz magnetic fields (the frequency used in European power grids) create electrical currents inside developing fetuses at different stages of pregnancy. They found that as fetuses grow larger, they absorb more electromagnetic energy, with the highest concentrations in skin and fat tissues, though levels remained below current safety guidelines.

Electromagnetic Radiofrequency Radiation Emitted from GSM Mobile Phones Decreases the Accuracy of Home Blood Glucose Monitors

Unknown authors · 2014

Researchers investigated whether radiofrequency radiation from a GSM mobile phone could alter the accuracy of home blood glucose monitors. Forty-five female nondiabetic students aged 17 to 20 years old participated in the study. The magnitude of changes between glucose readings was 1.07 ± 0.88 mg/dl in the group tested without electromagnetic fields, compared with 7.53 ± 4.76 mg/dl in the group tested while a GSM phone was ringing (P < 0.001).

The MOBI-Kids Study Protocol: Challenges in Assessing Childhood and Adolescent Exposure to Electromagnetic Fields from Wireless Telecommunication Technologies and Possible Association with Brain Tumor Risk

Sadetzki S et al · 2014

The MOBI-Kids study is a large international research project designed to investigate whether mobile phone and wireless device use increases brain tumor risk in young people aged 10-24. This protocol paper describes the study's design and methodology, which aims to include 1,000 brain tumor cases across 14 countries. The researchers outline their approach to overcome major challenges in studying EMF exposure and rare cancers in children and adolescents.

Excessive exposure to radiofrequency electromagnetic fields may cause the development of electrohypersensitivity

Unknown authors · 2014

This 2014 research paper by Dr. David Carpenter examines the connection between excessive radiofrequency electromagnetic field exposure and the development of electrohypersensitivity (EHS). The study suggests that prolonged exposure to RF-EMF radiation may trigger the onset of electromagnetic hypersensitivity symptoms in susceptible individuals. This adds to growing scientific recognition that EHS represents a real physiological response to EMF exposure rather than a psychological condition.

Neurodegenerative disease and magnetic field exposure in UK electricity supply workers

Sorahan T, Mohammed N · 2014

Researchers tracked 73,051 UK electrical workers for nearly 40 years to see if workplace magnetic field exposure increased their risk of developing Alzheimer's disease, motor neurone disease, or Parkinson's disease. The study found no statistically significant increase in any of these neurodegenerative diseases, even among workers with the highest magnetic field exposures. This suggests that occupational magnetic field exposure at the levels experienced by electrical workers does not elevate the risk of these brain diseases.

Effects of early-onset radiofrequency electromagnetic field exposure (GSM 900 MHz) on behavior and memory in rats.

Klose M et al. · 2014

German researchers exposed young rats to cell phone radiation (900 MHz) for nearly their entire lives, testing their learning and memory abilities at different ages. Despite using radiation levels up to 10 W/kg (much higher than typical phone exposure), they found no significant effects on behavior, memory, or brain development. This long-term study suggests that chronic cell phone radiation exposure starting in early development may not impair cognitive function.

Diverse Radiofrequency Sensitivity and Radiofrequency Effects of Mobile or Cordless Phone near Fields Exposure in Drosophila melanogaster.

Geronikolou S et al. · 2014

Researchers exposed fruit flies (Drosophila) to radiation from both mobile phones (900 MHz) and cordless phones (1880 MHz) to study reproductive effects. They found that mobile phone radiation significantly reduced egg laying in the second generation of flies, while cordless phone radiation showed only limited effects. The study suggests that lower frequency radiation may cause stronger biological impacts.

Mobile phone use and health symptoms in children.

Chiu CT, Chang YH, Chen CC, Ko MC, Li CY. · 2014

Researchers surveyed over 2,000 Taiwanese children aged 11-15 to examine whether mobile phone use was linked to health symptoms. They found that children who used mobile phones had 42% higher odds of experiencing headaches and migraines, and 84% higher odds of skin itching compared to non-users. Parents also reported that regular phone users had worse overall health compared to the previous year.

Decreased Survival of Glioma Patients with Astrocytoma Grade IV (Glioblastoma Multiforme) Associated with Long-Term Use of Mobile and Cordless Phones.

Carlberg M, Hardell L. · 2014

Swedish researchers analyzed survival data from 1,678 brain cancer patients and found that those who used mobile or cordless phones for more than 20 years had significantly worse survival rates. Patients with glioblastoma (the most aggressive brain cancer) who were long-term phone users were 2-3 times more likely to die sooner than non-users. This suggests that radiofrequency radiation from wireless phones may not only increase brain cancer risk but also make existing tumors more deadly.

Mobile telephone use effects on perception of verticality.

Bamiou DE et al. · 2014

Researchers tested whether mobile phone use affects people's sense of balance and spatial orientation by having participants wear phones against their ears for 30 minutes, then testing their ability to judge vertical and horizontal lines. They found that phones shifted people's perception of vertical away from the ear where the phone was placed, but this effect was due to the weight of the phone tilting the head rather than electromagnetic radiation.

Extremely low-frequency magnetic field exposure, electrical shocks and risk of Parkinson's disease.

van der Mark M et al. · 2014

Researchers studied whether exposure to extremely low-frequency magnetic fields (the type from power lines and electrical equipment) increases the risk of Parkinson's disease. They compared 444 Parkinson's patients with 876 healthy controls, examining both workplace and household electrical exposures. The study found no increased risk of Parkinson's disease from ELF magnetic field exposure or electrical shocks.

Investigation of EEG changes during exposure to extremely low-frequency magnetic field to conduct brain signals.

Shafiei SA, Firoozabadi SM, Tabatabaie KR, Ghabaee M. · 2014

Researchers investigated how extremely low-frequency magnetic fields (ELF-MFs) applied to different parts of the brain changed EEG power spectrum readings. EEG relative power spectrum was evaluated at several brain points when exposed to magnetic fields at 45, 17, 10, 5, and 3 Hz frequencies, at intensities of 0, 100, 240, or 360 μT across four sessions. Significant changes were observed in different EEG bands, and some exposures decreased the alpha band in frontal and central areas in the closed-eyes state.

Neuronal Cellular Responses to Extremely Low Frequency Electromagnetic Field Exposure: Implications Regarding Oxidative Stress and Neurodegeneration.

Reale M et al. · 2014

Researchers evaluated the effects of an electromagnetic wave at a magnetic field intensity of 1 mT and a frequency of 50-Hz on human SH-SY5Y cells, a well-characterized immortalized neuronal cell model. ELF-EMF exposure elevated the expression of NOS and O2−, which were countered by compensatory changes in antioxidant catalase activity and enzymatic kinetic parameters related to CYP-450 and CAT activity. Cytokine gene expression was additionally evaluated and found rapidly modified by ELF-EMF exposure. When co-exposed to H2O2-induced oxidative stress, ELF-EMF proved not as well counteracted, resulting in a decline in CAT activity and a rise in O2− levels.
