Researchers exposed pregnant mice to microwave radiation throughout pregnancy and tested their offspring's behavior. They found that prenatal microwave exposure increased anxiety-like behaviors in both male and female offspring, but only impaired learning and memory in males. This study provides the first evidence that microwave radiation can cause gender-specific developmental effects on the brain.

Polish researchers exposed human blood platelets to electromagnetic fields from car electronics, physiotherapy equipment, and LCD monitors for 30 minutes. They found that all three sources caused oxidative stress (cellular damage from harmful molecules called free radicals), with car electronics producing the strongest effects. This suggests that common electronic devices may damage our blood cells and potentially contribute to diseases linked to oxidative stress.

Researchers studied 186 power plant workers exposed to high-voltage lines for over 20 years and found elevated DNA damage markers in their blood. When workers took resveratrol supplements, these harmful effects significantly improved, suggesting antioxidants may protect against electromagnetic field damage.
Shckorbatov YG et al. · 2002
Researchers exposed human cheek cells to extremely high-frequency microwaves (37.5 and 18.75 GHz) at very low power levels and measured how the cell nuclei responded to electrical fields. They found that microwave exposure changed the electrical properties of cell nuclei and increased cell membrane permeability, with effects varying based on each person's initial cellular characteristics.

Researchers exposed guinea pigs to 50 Hz electric fields at various strengths (from 2,000 to 5,000 volts per meter) for 8 hours daily over three days, then measured markers of oxidative stress in brain tissue. The study found no statistically significant changes in cellular damage markers or antioxidant enzyme activity, though some non-significant trends were observed. This suggests that short-term exposure to these electric field levels may not cause measurable oxidative stress in brain tissue.
Türközer Z, Güler G, Seyhan N · 2008
Researchers exposed guinea pigs to powerful electric fields (the kind found near high-voltage power lines) for 8 hours daily over three days to see if it would damage brain tissue through oxidative stress. They found no statistically significant effects on brain cell damage markers or antioxidant defenses, even at the highest exposure levels tested. While this suggests these particular electric field exposures may not cause measurable brain oxidative damage in the short term, the researchers noted some non-significant trends that warrant further investigation.

Mice exposed to static electric fields (from power lines) for 35 days showed increased superoxide dismutase activity, an enzyme that fights cell damage. This suggests their liver cells were working harder to protect against electrical stress, indicating biological effects from field exposure.

Chinese researchers tested whether power line workers exposed to extremely low frequency electromagnetic fields while inspecting transformers and power lines showed changes in brain function and reaction times. They compared 310 inspection workers to 300 office staff using computerized tests measuring mental arithmetic, visual memory, and reaction speed. Despite many workers being exposed to electric fields above China's occupational safety standards, the study found no differences in cognitive performance between the two groups.

Researchers tested cognitive and brain function in 310 Chinese electrical workers regularly exposed to power line electromagnetic fields during equipment inspections, comparing them to 300 unexposed office workers. The study found no differences in memory, reaction time, or other brain performance measures between the two groups. This suggests that occupational exposure to power frequency electromagnetic fields may not impair basic cognitive abilities.
Budziosz J et al. · 2018
Researchers exposed rats to power-line frequency electromagnetic fields (50 Hz) for 28 days to study effects on brain oxidative stress, which occurs when harmful molecules damage cells. While overall oxidative stress markers remained unchanged, the study found decreased activity of protective antioxidant enzymes in most brain regions. This suggests that even when obvious damage isn't apparent, the brain's defense systems may be working harder under EMF exposure.
Fernie KJ, Bird DM. · 2001
Researchers exposed American kestrels (small falcons) to electromagnetic fields similar to those from power lines for nearly 24 hours daily over 91 days. The EMF-exposed birds showed signs of immune system stress and oxidative damage, including reduced blood proteins, lower red blood cell counts, and decreased protective antioxidants. This suggests that even relatively low-level EMF exposure can trigger biological stress responses in wildlife.

Gok DK et al. · 2016
Researchers exposed pregnant rats and their offspring to 50 Hz electric fields (the same frequency as household electricity) and measured brain wave responses to visual and touch stimuli. The exposed animals showed delayed brain responses and increased oxidative damage in both brain and retinal tissue compared to unexposed controls. This suggests that electric field exposure during development can impair nervous system function through cellular damage mechanisms.

Researchers exposed rats to 50 Hz electric fields (like those from power lines) for up to four weeks. High-intensity exposure significantly reduced brain responses that help detect sound changes, while increasing brain damage markers. This suggests electric field exposure may impair auditory processing abilities.

Researchers exposed rats to extremely low-frequency electric fields at two different strengths for one hour daily over 14 days, then measured brain and eye damage. They found that both exposure levels significantly increased oxidative stress (cellular damage from harmful molecules) and impaired visual processing in the brain. The higher exposure level caused more damage, suggesting a dose-response relationship between electric field strength and biological harm.

Researchers exposed rats to extremely low-frequency electric fields (the type generated by power lines) for one hour daily over two weeks. The exposed animals showed significant damage to brain and retinal tissue, including increased oxidative stress (cellular damage from free radicals) and disrupted visual processing. This suggests that even brief daily exposures to electric fields can harm the nervous system and vision.

Researchers exposed guinea pigs to power line frequency electric fields (12 kV/m for 8 hours daily over 7 days) to study protein damage and whether the antioxidant N-acetyl-L-cysteine could protect against it. The study found no significant protein damage from the electric field exposure alone, though it did reduce a protein synthesis marker in the liver. The antioxidant treatment showed some effects on protein markers, suggesting it may have biological activity in this context.

Researchers exposed lung tissue to extremely strong electric fields (12,000 volts per meter) for 8 hours daily over 7 days to test whether antioxidants could prevent damage. They found only minor increases in one marker of cellular damage (protein carbonyl), while other damage indicators remained unchanged. The study suggests that at these exposure levels, electric fields cause minimal lung tissue damage that antioxidants may help prevent.

Researchers exposed guinea pigs to electric fields at the strength found near power lines (12,000 volts per meter) and measured liver damage. The electric field exposure increased harmful oxidative stress markers and decreased the liver's natural antioxidant defenses. However, when the animals were given protective antioxidant compounds, the liver damage was significantly reduced.
