Researchers analyzed data from 83,884 mother-child pairs across five countries to examine whether cell phone use during pregnancy affects children's behavior. They found that mothers who used cell phones more frequently during pregnancy were more likely to have children with hyperactivity and attention problems by ages 5-7. The study suggests prenatal EMF exposure may influence brain development, though the researchers acknowledge other factors could explain these connections.

Australian researchers followed 412 primary school children for up to 3 years to see if using mobile phones and cordless phones affected their thinking abilities. They found mixed results - increased mobile phone use was linked to some changes in cognitive performance, including faster response times on some tasks but slower response times on others. The researchers concluded there was limited evidence that phone use significantly impacts children's cognitive function.

Researchers exposed mice to 900 MHz cell phone radiation for 6 hours daily over several weeks, then infected them with a common fungal pathogen (Candida) to test their immune response. The radiation-exposed mice showed delayed wound healing, higher infection levels in their skin, and increased susceptibility to life-threatening systemic infections. This suggests that chronic exposure to cell phone frequencies may weaken the immune system's ability to fight off infections.

Researchers exposed pregnant mice to cell phone radiation (900-1800 MHz) for 2 hours daily throughout pregnancy, then examined tissue damage in both mothers and their newborns after birth. They found significant oxidative stress (cellular damage from harmful molecules) in the heart, liver, kidney, brain areas of both mothers and offspring. This suggests that prenatal cell phone exposure may cause lasting tissue damage that affects both the pregnant mother and developing baby.

Researchers exposed young rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily during adolescence and examined their brain tissue. They found significant damage to the cerebellum, including fewer Purkinje cells (critical neurons for movement and coordination) and abnormal cell arrangement in exposed animals compared to unexposed controls. This suggests that even brief daily EMF exposure during brain development may cause lasting neurological damage.
Altuntas G et al. · 2017
Researchers exposed 30 emergency physicians to cell phone radiation (900-1800 MHz) for 15 minutes and tested their attention and concentration using standardized cognitive tests. Surprisingly, doctors exposed to the radiation actually performed better on selective attention tasks compared to those holding phones that were turned off. The study suggests short-term cell phone radiation exposure may temporarily enhance certain cognitive functions rather than impair them.

Researchers tracked radiofrequency radiation levels from cell phone towers across an urban area for over a year using a network of measurement devices. They found that RF exposure levels varied dramatically - up to 12,000 times higher at some locations and times compared to others, even though there was no overall trend of increasing or decreasing exposure. This variation followed daily and weekly patterns that could be predicted with 50% better accuracy when time factors were included in exposure models.

Researchers tested how extremely low frequency electromagnetic fields (ELF-EMF) affect brain cells from rats in laboratory conditions. They found that these magnetic fields directly activated specific electrical channels in hippocampus neurons (brain cells involved in memory and learning). This research helps explain how ELF-EMF exposure can influence brain cell activity at the cellular level.

Researchers tested deep brain magnetic stimulation (a targeted magnetic field therapy) on mice genetically engineered to develop Alzheimer's disease. They found that the magnetic treatment improved the mice's learning and memory, promoted growth of new brain cells in the memory center, and restored important brain chemicals needed for cognitive function. This suggests magnetic field therapy might help protect against Alzheimer's-related brain damage.
Sakhaie MH et al. · 2017
Researchers exposed mice with brain injury to extremely low-frequency electromagnetic fields (ELF-EMF) and found the exposure enhanced spatial memory and learning abilities. The EMF exposure also increased the production of new brain cells (neurogenesis) in the hippocampus, the brain region crucial for memory formation. This suggests ELF-EMF might have therapeutic potential for treating neurodegenerative conditions by promoting brain cell regeneration.
Koeman T et al. · 2017
Researchers followed over 120,000 Dutch adults for 17 years to study whether workplace exposures increase the risk of ALS (amyotrophic lateral sclerosis), a fatal neurological disease. Men with high occupational exposure to extremely low frequency magnetic fields (ELF-MF) had more than double the risk of dying from ALS compared to those with background exposure. This adds to growing evidence that ELF-MF exposure may contribute to this devastating disease that affects nerve cells controlling voluntary muscles.

Researchers exposed stem cells from rat bone marrow to 50 Hz electromagnetic fields (the same frequency as power lines) combined with nitric oxide, a natural cellular messenger. They found that EMF exposure combined with high levels of nitric oxide forced stem cells to transform into nerve cells, while low nitric oxide levels helped protect the cells' original stem cell properties. This suggests that EMF exposure can influence how our cells develop and differentiate, potentially affecting tissue repair and regeneration.

Researchers exposed rats to 50 Hz electromagnetic fields (the same frequency as household electricity) for seven days and found it caused anxiety-like behaviors. The EMF exposure increased harmful oxidative stress compounds in the brain region that controls stress responses. This suggests that common power line frequencies may directly affect brain chemistry and emotional well-being.
Dileone M et al. · 2017
Researchers tested how static magnetic fields affect brain activity in Parkinson's disease patients by applying magnetic stimulation to the motor cortex for 10 minutes. They found that the magnetic fields reduced brain excitability when patients were off their dopamine medications, but had no effect (or even opposite effects) when patients were on medication. This suggests that magnetic field effects on the brain depend heavily on dopamine levels and disease progression.
Clarke D et al. · 2017
Researchers exposed brain support cells called astrocytes to repetitive magnetic stimulation at different frequencies to see how they responded. They found that 1 Hz magnetic pulses caused a significant increase in calcium levels inside these cells, which is a sign of cellular activation. This suggests that magnetic fields can directly influence brain cells beyond just neurons, potentially explaining some of the biological effects seen with magnetic field exposure.
Carrasco-López C et al. · 2017
Researchers used powerful static magnetic fields placed over participants' heads to stimulate brain areas involved in touch sensation. They found that this magnetic stimulation enhanced people's ability to detect weak touch sensations by increasing specific brain wave patterns called alpha oscillations. This suggests that magnetic fields can directly influence how our brains process sensory information.

Researchers studied 40 people living within 80 meters of cell phone towers and compared them to controls living 300 meters away. They found that those closer to towers had significantly more DNA damage in their blood cells and reduced levels of protective antioxidants like glutathione, catalase, and superoxide dismutase. This suggests that chronic exposure to radiofrequency radiation from cell towers may compromise the body's natural defenses against cellular damage.

Researchers exposed female rats to WiFi-frequency radiation (2.45GHz) for 4 hours daily over 45 days and found significant brain changes including memory problems, increased anxiety, and markers of brain cell death. The radiation also damaged the brain's natural antioxidant defenses and altered the structure of neurons that carry electrical signals. This study suggests that prolonged exposure to WiFi radiation at the frequency used by most wireless devices may harm brain function and structure.

Turkish researchers exposed young male rats to cell phone frequency radiation (900 MHz) for one hour daily during their developmental period and examined kidney and bladder tissues. They found significant increases in oxidative stress markers and observed cellular damage including tissue degeneration and increased cell death in both organs. The study demonstrates that even brief daily exposure to radiofrequency radiation during development can cause measurable harm to vital organs.

Researchers exposed young mice to 10 GHz microwave radiation (similar to some WiFi and cellular frequencies) for 2 hours daily over 15 days and found significant damage to developing brains. The exposed mice showed impaired spatial memory, disrupted brain chemistry, and visible tissue damage in key brain regions including the hippocampus. These effects persisted weeks after exposure ended, suggesting the developing brain is particularly vulnerable to microwave radiation.

Researchers exposed female mice to 1800 MHz mobile phone radiation (the frequency used by GSM networks) and found it significantly damaged their reproductive systems. The radiation increased harmful stress molecules in the brain, ovaries, and uterus while reducing fertility hormones and the number of healthy egg follicles. This suggests that mobile phone radiation may impair female fertility through cellular stress pathways.

Researchers exposed male mice to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for 4-8 hours daily over 35 days and found significant damage to sperm-producing cells in the testes. The radiation disrupted the normal development of sperm cells, caused DNA damage, and reduced sperm counts by interfering with cellular energy production. While the effects were reversible after stopping exposure, the study demonstrates how RF radiation can impair male fertility at the cellular level.

Researchers exposed male rats to cell phone radiation for 1-3 hours daily over 28 days and found significant damage to reproductive function. The radiation caused cellular degeneration in testicles, increased harmful oxidative stress, and decreased key reproductive hormones including testosterone. This suggests that regular cell phone exposure may impair male fertility through biological mechanisms that worsen with longer exposure times.

Researchers exposed rats to WiFi signals for 2 hours daily over 20 days, with some rats also experiencing stress. WiFi exposure increased anxiety-like behavior and caused oxidative stress (cellular damage from free radicals) in the brain, with effects becoming worse when combined with stress. The study suggests that everyday WiFi exposure may affect brain chemistry and behavior, particularly in stressful situations.
Othman H et al. · 2017
Researchers exposed pregnant rats to WiFi signals (2.45GHz) for 2 hours daily throughout pregnancy and tracked their offspring's brain development. The study found that prenatal WiFi exposure delayed early neurodevelopment in the first 17 days after birth and caused oxidative stress (cellular damage from harmful molecules) in the brain at 28 days old. This suggests that WiFi exposure during pregnancy may affect early brain development in offspring.
