Symptom reporting after the introduction of a new high-voltage power line: A prospective field study

Unknown authors · 2015

Dutch researchers tracked over 1,200 residents before and after a new high-voltage power line was built near their homes. People living within 300 meters reported significantly more health symptoms and stronger beliefs that the power line caused their complaints, compared to those living farther away. The increase in symptoms began even before the power line was switched on.

Unknown authors · 2015

Turkish researchers exposed rats to 2100 MHz radiofrequency radiation (3G mobile phone frequency) for 6 hours daily over 10 or 40 days and examined their parotid salivary glands. The study found significant tissue damage in exposed animals, including changes to gland cells, blood vessels, and cellular structure, with more severe damage after longer exposure periods.

Unknown authors · 2015

Italian researchers monitored air pollution in northern Italy cities using bacteria, human cells, and plants to detect genetic damage from airborne chemicals. They found that winter air contained significantly more toxic compounds that caused DNA damage and mutations across all three test systems. The study demonstrates that urban air pollution creates measurable genetic harm in living organisms.

Influence of electromagnetic field (1800 MHz) on lipid peroxidation in brain, blood, liver and kidney in rats

Bodera P et al. · 2015

Researchers exposed rats to 1800 MHz radiofrequency radiation (the same frequency used in cell phones) for 15 minutes, five times daily, and measured oxidative damage in their organs. They found increased lipid peroxidation (cellular damage from oxidation) in the brain, blood, and kidneys of exposed animals. This suggests that repeated cell phone-frequency radiation exposure may cause oxidative stress damage to vital organs.

Can prenatal exposure to a 900 MHz electromagnetic field affect the morphology of the spleen and thymus, and alter biomarkers of oxidative damage in 21-day-old male rats?

Hancı H et al. · 2015

Researchers exposed pregnant rats to 900 MHz cell phone radiation for one hour daily and examined the immune organs (spleen and thymus) of their male offspring at 21 days old. The prenatal radiation exposure caused significant oxidative damage and structural abnormalities in these critical immune system organs. This suggests that EMF exposure during pregnancy may compromise immune system development in offspring.

Influence of electromagnetic field (1800 MHz) on lipid peroxidation in brain, blood, liver and kidney in rats.

Bodera P et al. · 2015

Researchers exposed rats to 1800 MHz radiofrequency radiation (similar to cell phone signals) five times for 15 minutes each and measured oxidative damage in their organs. The EMF exposure increased lipid peroxidation (a marker of cellular damage from free radicals) in the brain, blood, and kidneys, particularly when combined with a pain medication. This suggests that even brief, repeated exposure to cell phone-level radiation may cause measurable oxidative stress in vital organs.

EMF radiation at 2450MHz triggers changes in the morphology and expression of heat shock proteins and glucocorticoid receptors in rat thymus.

Misa-Agustiño MJ et al. · 2015

Researchers exposed rats to 2.45 GHz radiofrequency radiation (the same frequency used in microwave ovens and WiFi) and found it caused visible damage to the thymus, a key immune system organ. The radiation triggered cellular stress responses, increased blood vessel leakage, and altered stress proteins even at levels below those that cause heating. This suggests that EMF exposure can disrupt immune system function through non-thermal biological mechanisms.

The effect of exposure of rats during prenatal period to radiation spreading from mobile phones on renal development.

Bedir R et al. · 2015

Turkish researchers exposed pregnant rats to 900 MHz electromagnetic fields (the same frequency used by many cell phones) during the first 20 days of pregnancy and examined the kidney development of their offspring. They found that prenatal EMF exposure caused structural abnormalities in the developing kidneys, including tissue congestion, tubular defects, and increased cell death. This suggests that EMF exposure during pregnancy may interfere with normal organ development in the fetus.

Enhancement of Cortical Network Activity in vitro and Promotion of GABAergic Neurogenesis by Stimulation with an Electromagnetic Field with a 150 MHz Carrier Wave Pulsed with an Alternating 10 and 16 Hz Modulation.

Gramowski-Voß A et al. · 2015

German researchers exposed developing mouse brain tissue to electromagnetic fields combining low frequencies (10 and 16 Hz) with a higher carrier frequency (150 MHz) for 10 days. The exposure accelerated brain development, increased electrical activity, and promoted the growth of specific neurons called GABAergic neurons, which help regulate brain function. The researchers suggest this type of electromagnetic stimulation might have therapeutic potential for treating neurodegenerative diseases like Alzheimer's.

Structural and Ultrastructural Study of Rat Liver Influenced by Electromagnetic Radiation.

Holovská K et al. · 2015

Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 3 hours daily over 3 weeks at power levels of 2.8 mW/cm². They found liver damage including inflammation, blood vessel dilation, and cellular changes including fat accumulation and dying liver cells. This suggests that chronic exposure to common microwave frequencies may harm liver function.

The effects of 2100-MHz radiofrequency radiation on nasal mucosa and mucociliary clearance in rats.

Aydoğan F et al. · 2015

Researchers exposed rats to 2100 MHz radiofrequency radiation (simulating 3G cell phone signals) for 6 hours daily over 10 or 40 days to study effects on nasal tissue and mucus clearance. The exposed rats showed significant damage to nasal tissue, including cell death, loss of protective cilia (tiny hair-like structures), and impaired ability to clear mucus from nasal passages. This matters because our nasal passages are a primary defense against airborne pathogens, and cell phone radiation may be compromising this natural protective mechanism.

Adibzadeh F et al, (January 2015) Impact of head morphology on local brain specific absorption rate from exposure to mobile phone radiation, Bioelectromagnetics. 2015 Jan;36(1):66-76. doi: 10.1002/bem.21885

Unknown authors · 2015

Researchers tested how different head shapes and sizes affect radiation absorption from cell phones using computer models of 20 different heads. They found dramatic variations in brain radiation exposure - up to 16 times higher in some people compared to others when using phones at the same power level. This suggests that standard safety testing using only generic head models may not protect everyone equally.

Cell oxidation–reduction imbalance after modulated radiofrequency radiation.

Marjanovic AM, Pavicic I, Trosic I, · 2015

Researchers exposed hamster cells to cell phone-level radiofrequency radiation (1800 MHz) for 10, 30, and 60 minutes to study cellular damage. They found that even brief 10-minute exposures significantly increased reactive oxygen species (cellular stress markers) and disrupted the cells' natural balance between oxidation and antioxidant defense. This suggests that RF radiation at levels similar to cell phone use can trigger oxidative stress in living cells.

Epilepsy but not mobile phone frequency (900 MHz) induces apoptosis and calcium entry in hippocampus of epileptic rat: involvement of TRPV1 channels.

Nazıroğlu M, Özkan FF, Hapil SR, Ghazizadeh V, Çiğ B · 2015

Turkish researchers exposed brain cells from epileptic rats to 900 MHz mobile phone radiation for one hour to see if it would worsen brain damage. They found that epilepsy itself caused significant cell death and oxidative stress in the hippocampus (the brain's memory center), but adding mobile phone radiation didn't make these effects any worse. This suggests that in already-damaged brain tissue, short-term mobile phone exposure may not add additional harm beyond what the underlying condition already causes.

Epilepsy But Not Mobile Phone Frequency (900 MHz) Induces Apoptosis and Calcium Entry in Hippocampus of Epileptic Rat: Involvement of TRPV1 Channels.

Nazıroğlu M, Ozkan FF, Hapil SR, Ghazizadeh V, Ciğ B · 2015

Researchers exposed brain cells from epileptic rats to 900 MHz mobile phone radiation for one hour to see if it worsened seizure-related brain damage. The epilepsy itself caused significant cell death, oxidative stress, and calcium influx in the hippocampus (a brain region crucial for memory), but the mobile phone radiation didn't add any additional harmful effects. This suggests that in already-damaged brain tissue, 900 MHz EMF exposure may not worsen the cellular damage beyond what the disease itself causes.

Epilepsy but not mobile phone frequency (900 MHz) induces apoptosis and calcium entry in hippocampus of epileptic rat: involvement of TRPV1 channels.

Nazıroğlu M, Özkan FF, Hapil SR, Ghazizadeh V, Çiğ B. · 2015

Researchers exposed brain cells from epileptic rats to 900 MHz cell phone radiation for one hour to see if it would worsen brain damage. While epilepsy itself caused significant cellular damage including cell death and calcium influx, the cell phone radiation did not add any additional harmful effects. This suggests that 900 MHz EMF exposure may not exacerbate existing brain conditions like epilepsy.

Cancer & TumorsNo Effects Found

Exposure to 3G mobile phone signals does not affect the biological features of brain tumor cells.

Liu YX et al. · 2015

Researchers exposed human brain tumor cells to 3G mobile phone radiation (1950-MHz) for up to 48 hours at high power levels (SAR of 5 W/kg) to see if the radiation would promote tumor growth or change cell behavior. They found no significant effects on cell growth, gene expression, or tumor formation ability. This suggests that 3G signals at these exposure levels don't act as tumor-promoting agents in already-existing brain cancer cells.

Everyday exposure to power frequency magnetic fields and associations with non-specific physical symptoms

Unknown authors · 2015

Dutch researchers measured 24-hour power line frequency magnetic field exposure in 99 adults and assessed their non-specific physical symptoms like fatigue and headaches. Women with higher exposure levels (above 0.09 microTesla) were 8.5 times more likely to report multiple physical symptoms. The study suggests a connection between everyday electromagnetic field exposure and health complaints, though the small sample size limits definitive conclusions.

Could Magnetic Fields Affect the Circadian Clock Function of Cryptochromes? Testing the Basic Premise of the Cryptochrome Hypothesis (ELF Magnetic Fields)

Unknown authors · 2015

Researchers examined whether weak 50/60 Hz magnetic fields from power lines could disrupt our internal body clocks by affecting cryptochromes, special proteins that help regulate circadian rhythms. The study tested the basic scientific premise behind this 'cryptochrome hypothesis' by looking at how static magnetic fields might change these proteins' chemical balance. This research aims to understand if everyday electromagnetic exposure could be throwing off our natural sleep-wake cycles.

Could Magnetic Fields Affect the Circadian Clock Function of Cryptochromes? Testing the Basic Premise of the Cryptochrome Hypothesis (ELF Magnetic Fields)

Unknown authors · 2015

Researchers examined whether weak 50/60 Hz magnetic fields could disrupt circadian rhythms by affecting cryptochrome proteins, which help regulate our body's internal clock. The study tested the basic premise that Earth-strength magnetic fields can alter the chemical balance of cryptochromes in the retina. This research explores a potential biological mechanism for how power line frequencies might affect sleep and circadian health.

Do signals of a hand-held TETRA transmitter affect cognitive performance, well-being, mood or somatic complaints in healthy young men? Results of a randomized double-blind cross-over provocation study.

Sauter C et al. · 2015

German researchers exposed 30 healthy young men to TETRA radio signals (used by police and emergency services) for 2.5 hours to test effects on thinking, mood, and physical symptoms. They found no negative impacts on cognitive performance or well-being, with some participants actually showing slight improvements in certain memory tasks. The study suggests short-term exposure to TETRA signals doesn't harm mental function in healthy adults.

Hori T et al, (March 2015) Exposure to 50 Hz electric fields reduces stress-induced glucocorticoid levels in BALB/c mice in a kV/m- and duration- dependent manner, Bioelectromagnetics

Unknown authors · 2015

Japanese researchers exposed mice to 50 Hz electric fields (the same frequency as power lines) while subjecting them to stress through immobilization. They found that moderate electric field exposure at 10 kV/m significantly reduced stress hormone levels, but higher exposures actually increased them. This suggests electric fields can influence the body's stress response in complex, dose-dependent ways.
