Researchers exposed male fruit flies to static magnetic fields as low as 20 Gauss (about 40 times Earth's natural magnetic field) and found it significantly increased their courtship behavior. The effect depended on cryptochrome, a protein that helps animals sense magnetic fields and is also found in humans. This study demonstrates that relatively weak magnetic fields can alter behavior through biological magnetic sensing mechanisms.

Researchers exposed mice to extremely low frequency magnetic fields (the type generated by power lines and electrical appliances) to study effects on depression-like behavior. They found that short-term exposure (2 hours) had no effect, but long-term exposure (2 hours daily for 2 weeks) actually reduced depressive symptoms in the mice. The study suggests this effect may work through changes in nitric oxide levels in the brain.

Researchers exposed embryonic brain stem cells to 50 Hz electromagnetic fields from power lines and electrical devices. The EMF exposure significantly enhanced the cells' development into neurons and promoted growth of neural connections. This suggests electromagnetic fields could influence brain formation during early development.

Researchers exposed genetically modified mice with Alzheimer's disease to extremely low frequency magnetic fields (50Hz, 500μT) for three months daily. The magnetic field exposure improved cognitive function, reduced brain cell death, and decreased tau protein abnormalities that are hallmarks of Alzheimer's disease. This suggests that controlled magnetic field exposure might have therapeutic potential for neurodegenerative conditions.

Researchers exposed human neuroblastoma cells (a type of brain cancer cell) to 50 Hz magnetic fields at 1 milliTesla and found the fields made the cancer cells grow faster and become more aggressive. The magnetic field exposure triggered protective mechanisms in the cancer cells that helped them survive and multiply more effectively. This suggests that power frequency magnetic fields might promote the growth of existing brain tumors.

Researchers exposed human brain-like cells to a 50 Hz magnetic field (the type emitted by power lines and household appliances) for 4 hours and found significant changes in cellular proteins. The magnetic field caused proteins to clump together abnormally and altered their structural bonds, which are critical for proper brain cell function. These molecular changes suggest that everyday electromagnetic fields may disrupt normal cellular processes in brain tissue.

Researchers exposed rats to 2450 MHz microwave radiation (WiFi frequency) for 6 minutes and found significant heart muscle cell death. The microwaves disrupted cellular energy production and increased harmful stress, demonstrating how brief microwave exposure can damage cardiovascular tissue through specific biological mechanisms.
Kerimoğlu G et al. · 2016
Researchers exposed adolescent male rats to cell phone-level radiation (900 MHz) for one hour daily during their development and examined their hearts as adults. The exposed rats showed significant heart damage including increased oxidative stress, structural changes to heart muscle cells, and higher rates of cell death compared to unexposed controls. This suggests that EMF exposure during critical developmental periods may cause lasting cardiovascular damage.

Researchers exposed rats to electromagnetic pulses (EMP) at extremely high levels and found that these exposures activated microglia, the brain's immune cells, causing inflammation. The study identified that this brain immune response happened through a specific cellular pathway called p38 MAPK, and the effects were measurable within hours of exposure. This research helps explain one biological mechanism by which electromagnetic fields might affect brain function.

Researchers exposed human brain tumor cells (neuroblastoma) to 50 Hz magnetic fields at 100 microtesla - similar to levels near power lines - for various time periods. The magnetic field exposure triggered specific cellular pathways that increased cell proliferation, with the effects appearing to be mediated by reactive oxygen species (free radicals). This suggests that power frequency magnetic fields can stimulate abnormal cell growth through oxidative stress mechanisms.

Researchers exposed mice with Alzheimer's disease to a 50 Hz magnetic field (the type from power lines) for 20 hours daily over 3 months. The magnetic field exposure improved the mice's memory and learning abilities, while also reducing toxic protein buildup in their brains that's characteristic of Alzheimer's. This suggests that certain types of electromagnetic fields might actually have protective effects on brain health rather than harmful ones.

Researchers exposed human cells to a 50-Hz magnetic field (the same frequency as power lines) and found it protected cells from dying when they were later exposed to a toxic chemical. The magnetic field triggered the release of reactive oxygen species from mitochondria (the cell's power plants), which activated protective cellular pathways. This suggests extremely low frequency magnetic fields can influence fundamental cellular survival mechanisms.

Chinese researchers exposed human cells to magnetic fields at levels similar to those found near power lines and appliances (0.4 mT for 60 minutes). They discovered that this exposure damaged the powerhouses of cells (mitochondria) by triggering a harmful chain reaction involving oxidative stress. The damage occurred through a specific biological pathway that could be blocked with antioxidants, suggesting the effects are real and measurable.

Researchers exposed drug-resistant brain cancer cells to pulsed electromagnetic fields (PEMF) at 75 Hz for brief periods over five days, then tested how well the cells handled oxidative stress. The PEMF treatment boosted the cells' antioxidant defenses and reduced harmful reactive oxygen species when challenged with hydrogen peroxide. This suggests that specific electromagnetic field exposures might actually help protect cells from oxidative damage rather than harm them.

Turkish researchers exposed rats to cell phone radiation at 900 MHz and 1800 MHz for 20 minutes. Both frequencies increased blood-brain barrier permeability in male rats, while only 900 MHz affected females. This protective brain barrier normally prevents harmful substances from entering the brain.
Erdem Koç G et al. · 2016
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.

French researchers exposed rats to cell phone radiation (900 MHz) for 15-45 minutes and found that even brief exposures caused brain inflammation and memory problems. At exposure levels similar to what heavy cell phone users experience (6 W/kg), rats showed a 119% increase in brain inflammation markers and reduced long-term memory performance. The study demonstrates that radiofrequency radiation can trigger inflammatory responses in the brain that directly impact cognitive function.
