Researchers exposed brain cells to extremely low frequency magnetic fields (the type from power lines) at levels as low as 10 microtesla for 24 hours. The study found significant DNA damage in human neuroblastoma cells and increased oxidative stress in rat brain cells. These effects occurred at magnetic field levels that are commonly encountered near electrical appliances and power infrastructure.

Researchers exposed rats to microwave radiation (30 mW/cm²) for 2 months and discovered that genetic variations in the brain's GRIN2B gene determine whether animals experience memory problems from the exposure. Rats with a specific genetic variant (TT genotype) showed memory impairment and brain chemistry changes after microwave exposure, while those with other variants (CC and CT) were protected from these effects.

Pregnant rats exposed to cell phone radiation (900 MHz) for one hour daily had offspring with fewer brain cells in the hippocampus, the memory center. Melatonin and omega-3 supplements during pregnancy prevented this brain damage, suggesting potential protective strategies for human prenatal development.

Turkish researchers studied 1,031 men seeking fertility treatment to compare how cell phone use versus wireless internet affects sperm quality. They found that wireless internet use significantly reduced sperm motility (movement) and total motile sperm count, while cell phone use showed minimal impact. This suggests WiFi radiation may pose greater risks to male fertility than phone radiation.

Turkish researchers exposed pregnant rats and their newborns to WiFi radiation (2.45 GHz) for one hour daily, five days per week from pregnancy through three weeks of age. The study found increased oxidative stress in both brain and liver tissue, with reduced antioxidant defenses including glutathione and vitamins A, C, and E. The brain appeared more vulnerable to damage than the liver in developing animals.

This is a review article examining the effects of electromagnetic field (EMF) exposure on the endocrine system in children and adolescents. The authors discuss concerns about EMF impacts on thyroid function, adrenal hormones, glucose homeostasis, and melatonin levels, noting that while international guidelines lack definitive evidence of causality, a growing body of animal and computational studies suggests potential endocrine and metabolic effects from EMF exposure in developing organisms.

This record appears to be a collection of related citations rather than a single study with an abstract. The titles suggest these studies examined associations between mobile phone and cordless phone use and brain tumor rates in Swedish populations, with analyses of temporal trends from the 1980s-2015 period across different age groups.
Morgan et al · 2015
This 2015 review by Morgan and colleagues analyzed existing research on mobile phone radiation and brain tumors, concluding that radiofrequency fields should be classified as a Group 2A 'probable' human carcinogen. The authors highlighted the French CERENAT study showing increased glioma risk from long-term mobile phone use and argued that current evidence meets the criteria for upgrading the cancer classification.

Researchers exposed rats to 100 microtesla, 50 Hz extremely low frequency electromagnetic fields (the type from power lines and electrical wiring) for 12 weeks to see if it affected memory or caused Alzheimer's-like brain changes. The study found no cognitive impairment, no changes in amyloid-beta protein levels (a hallmark of Alzheimer's), and no visible damage to brain neurons. This suggests short-term ELF-EMF exposure at typical environmental levels may not trigger Alzheimer's disease processes in rats.

This study examined how static magnetic fields (SMF, 2 mT) and extremely low frequency magnetic fields (ELF MF, 50 Hz, 2 mT) affect neuronal population activity in the antennal lobe of longhorn beetles (Morimus funereus) using wavelet analysis of local field potentials. The researchers found that prolonged ELF MF exposure produced irreversible changes in neural oscillations, including increased activity in the 4-8 Hz band and decreased activity in slower (1-2 Hz) and faster (64-128 Hz) frequency ranges, while SMF exposure did not produce detectable effects within the investigated timeframe.

This study exposed rats with Alzheimer's-like symptoms to 50 Hz electromagnetic fields (the same frequency as electrical power lines) for 60 days and found unexpected improvements in memory and reduced brain damage. The rats showed better performance in maze tests and less hippocampal deterioration compared to unexposed Alzheimer's rats. The findings suggest that under specific conditions, certain EMF exposures might influence neurodegenerative disease progression, though the mechanisms remain unclear.

This large Dutch study tracked over 1,500 workers for 17 years to examine occupational exposures and dementia risk. Researchers found that men exposed to extremely low frequency magnetic fields (ELF-MF) and metals at work showed elevated rates of non-vascular dementia-related death. The findings add to growing evidence that chronic workplace EMF exposure may affect long-term brain health.

Researchers exposed neural progenitor cells from ischemic (oxygen-deprived) brains to 50 Hz electromagnetic fields at 0.4 mT and found these fields significantly enhanced both cell proliferation and neuronal differentiation. The effect worked through the Akt cellular pathway and was demonstrated in both embryonic and adult brain cells. This suggests extremely low-frequency EMFs might stimulate brain repair mechanisms after injury.

Researchers used electric fields to study how Schwann cells (nerve-supporting cells) migrate toward damaged areas in the nervous system. They found that these cells move toward the positive electrode when exposed to electric fields of 50-200 mV/mm, and stronger fields caused more directed movement. The study identified over 2,600 genes that changed expression during this electric field-guided migration.

Researchers exposed male mice to 50 Hz magnetic fields at power line frequencies (10-300 µT) for 2-15 hours and tested for genetic mutations in sperm and blood cells. They found no significant DNA damage in blood cells and only marginal increases in sperm mutations that weren't dose-dependent. The study suggests that ELF magnetic field exposure at these levels produces minimal genetic damage compared to X-ray radiation.

This 2015 study measured occupational exposure to extremely-low-frequency magnetic fields (ELF-MF) in 21 electric arc welders and assessed potential DNA damage using the comet assay on peripheral blood leukocytes. The results showed significantly decreased tail intensity and tail moment in exposed welders compared to 21 control subjects, suggesting reduced primary DNA damage, though the authors noted the small sample size and potential confounding effects from metal exposures like chromium and nickel.

Researchers exposed pregnant mice and their offspring to power line frequency magnetic fields (50 Hz, 65 μT) from mid-pregnancy through weaning to study genetic damage. The study found slight DNA damage in blood cells only after maximum exposure, which disappeared after exposure ended, but magnetic fields appeared to affect how male reproductive cells responded to X-ray radiation.

Researchers studied 142 workers at 132 kV electrical substations and compared them to 151 unexposed controls, measuring stress hormones, DNA damage, and cellular oxidative stress. Workers with higher EMF exposure showed elevated epinephrine (stress hormone) levels, increased DNA damage, and higher oxidative stress markers. The study suggests that occupational exposure to extremely low-frequency electromagnetic fields may affect the body's stress response and cellular health.
