Researchers exposed brain cells called astrocytes to 918 MHz radiofrequency radiation (similar to cell phone signals) along with proteins that cause Alzheimer's disease damage. Surprisingly, they found that the RF exposure actually reduced harmful oxidative stress and protected the cells from damage caused by the Alzheimer's proteins. The study suggests that certain RF frequencies might have therapeutic potential for treating Alzheimer's disease.

Researchers exposed mice to magnetic fields from power lines during sleep to test effects on their internal body clocks. The magnetic fields caused only minor changes in movement, while light exposure significantly disrupted sleep hormones. Power line magnetic fields don't appear to disrupt circadian rhythms.

Researchers exposed rats with chemically-induced dementia to pulsed magnetic fields (10 mT at 20 Hz) and found dramatic improvements in learning and memory abilities. The treated rats showed 66% faster escape times in maze tests and 55% shorter swimming distances compared to untreated dementia rats. The magnetic field exposure also increased expression of genes linked to brain growth and repair, suggesting the fields may help protect against cognitive decline.

Researchers exposed mice to extremely strong electric fields (35,000 volts per meter) for 49 days to compare how static fields versus power frequency fields affect learning and memory. They found that static electric fields had no effect on cognitive ability, while power frequency electric fields actually improved the mice's performance on memory tests after 33 days of exposure.

Turkish researchers exposed rats to cell phone radiation at three different frequencies (900, 1800, and 2100 MHz) for 2 hours daily over 6 months to study brain effects. They found increased DNA damage and oxidative stress in brain tissue across all frequency groups compared to unexposed control rats. This suggests that chronic exposure to the radiofrequency radiation emitted by mobile phones may harm brain cells at the genetic level.
Jeong YJ et al. · 2018
Researchers exposed middle-aged mice to cell phone-level radiofrequency radiation (1950 MHz) for 8 months to see if it worsened age-related brain damage. While the aging mice showed expected increases in brain oxidative stress, DNA damage, and inflammation markers, the RF exposure didn't make any of these problems worse. The study suggests that long-term exposure to this type of radiation may not accelerate brain aging processes.
Esmaeilpour K et al. · 2018
Researchers studied whether low-frequency electrical stimulation (1 Hz) could help reverse memory problems caused by seizures in rats. They found that applying brief electrical stimulation treatments after seizures not only restored learning and memory abilities but also protected brain cells from seizure-related damage. This suggests that controlled electrical stimulation might offer a therapeutic approach for treating cognitive problems in epilepsy patients.

Researchers exposed male mice to 900 MHz radiofrequency radiation (similar to cell phone signals) for 6 hours daily over 35 days and found significant damage to sperm-producing cells, including DNA damage, reduced sperm count, and abnormal sperm shape. However, when mice also received melatonin supplements, these harmful effects were largely prevented or reversed. This suggests that RF radiation can impair male fertility, but antioxidants like melatonin may offer protection.

Researchers exposed rats to Wi-Fi radiation (2.4 GHz) for 4 hours daily over 45 days and found it significantly impaired the pancreas's ability to produce insulin while causing elevated blood sugar levels. The Wi-Fi exposure also increased harmful oxidative stress in pancreatic tissue and reduced the body's natural antioxidant defenses. This suggests that chronic Wi-Fi radiation exposure may interfere with blood sugar regulation, a critical function for metabolic health.

Turkish researchers exposed adolescent male rats to 900 MHz electromagnetic fields (the frequency used by many cell phones) for one hour daily throughout their entire teenage development period. They found significant nerve damage in the sciatic nerve, including structural changes and increased oxidative stress markers that indicate cellular damage. This suggests that regular EMF exposure during critical developmental periods may harm the peripheral nervous system.

Researchers exposed rats to Wi-Fi radiation (2.45 GHz) continuously for 10 weeks to study its effects on cellular defense systems. They found that Wi-Fi exposure significantly weakened the animals' antioxidant defenses, reducing the activity of key protective enzymes that normally protect cells from damage. This suggests that chronic Wi-Fi exposure may compromise the body's natural ability to defend against cellular stress.
Comelekoglu U et al. · 2018
Turkish researchers exposed rats to 1800 MHz radiofrequency radiation (the same frequency used by many cell phones) for one hour daily over four weeks and found significant damage to the sciatic nerve, which controls leg function. The nerve damage included slower electrical signals, increased oxidative stress, and physical deterioration of nerve fibers. However, when rats were also given paricalcitol (a vitamin D derivative), the nerve damage was partially prevented.

Researchers exposed pregnant mice to cell phone radiation for 2 hours daily, then measured cellular damage in mothers and newborns. Both showed increased oxidative stress (cellular damage linked to aging and disease) in brain, heart, and liver tissues, suggesting pregnancy EMF exposure may harm both mother and developing baby.
Martínez-Sámano J et al. · 2018
Researchers exposed rats to extremely low frequency electromagnetic fields (the type emitted by power lines and electrical wiring) for 21 days and found it triggered the same stress response as physical restraint stress. The EMF exposure altered brain chemistry, specifically changing fat composition and increasing oxidative damage (cellular wear and tear) in different brain regions.

Young female rats showed the most dramatic effects, with altered patterns in both brain tissue and blood, suggesting chronic EMF exposure may disrupt normal brain function.
Dinčić M et al. · 2018
Researchers exposed rats to weak static magnetic fields (1 mT) for 50 days and examined brain enzyme activity. They found that magnetic field exposure significantly increased the activity of key brain enzymes involved in nerve communication and energy metabolism, while also causing oxidative stress damage. These enzymes play important roles in neurological diseases, suggesting that even weak magnetic fields can alter brain chemistry.

Researchers injected rats with Alzheimer's-causing proteins and then exposed them to magnetic fields (50 Hz at 10 milliTesla) for 14 days. The magnetic field exposure significantly improved memory and learning abilities in the Alzheimer's rats, as measured by maze tests. This suggests that certain electromagnetic fields might help protect brain function in neurodegenerative diseases.
Li R et al. · 2018
Researchers exposed mouse sperm cells to cell phone-level radiofrequency radiation (4 W/kg SAR) for 24 hours and found it caused DNA damage. However, the cells activated a protective mechanism called autophagy (cellular self-cleaning) that helped reduce this damage. When researchers blocked this protective response, DNA damage increased significantly.

Researchers exposed rats to magnetic fields from power lines for 2 hours daily over a month, finding significant blood damage and reduced antioxidant defenses. Myrtle plant extract prevented these harmful effects, suggesting magnetic field exposure causes oxidative stress but natural compounds may offer protection.
Glinka M et al. · 2018
Polish researchers exposed mouse skin cells (fibroblasts) to static magnetic fields ranging from 100 to 700 milliTesla to see how it affected their antioxidant defense systems. They found that the magnetic fields actually decreased the activity of two key antioxidant enzymes but didn't cause oxidative stress or damage the cells' energy production. This suggests static magnetic fields may have mild antioxidant-like effects rather than harmful oxidative effects.
