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 breast cancer cells to 50 Hz electromagnetic fields (household electricity frequency) for 30 minutes. Stronger fields significantly altered genes that protect cells from damage, especially during on-off exposure patterns. This shows brief EMF exposure can disrupt cellular defense systems.

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 rat brain cells to 50 Hz magnetic fields and found significant damage including cell death and DNA harm. However, natural compounds from lotus seed pods prevented most of this damage, suggesting magnetic fields can harm brain cells but certain antioxidants may offer protection.
Esmekaya MA et al. · 2016
Researchers exposed mice to cell phone radiation (900 MHz) before, during, and after chemically-induced seizures to study brain effects. They found that radiation exposure significantly increased oxidative damage and inflammatory markers in brain tissue compared to seizures alone. This suggests cell phone radiation may worsen brain vulnerability during neurological stress, potentially making seizure-related brain damage more severe.
Şahin D et al. · 2016
Researchers exposed female rats to 3G mobile phone radiation (2100 MHz) for either 10 or 40 days to study DNA damage in brain tissue. They found increased DNA damage after 10 days of exposure, but surprisingly, this damage decreased after 40 days, suggesting the brain may develop protective mechanisms over time. The study used radiation levels similar to what you'd experience during heavy mobile phone use.
Ansari AM et al. · 2016
Researchers exposed mice to extremely low frequency magnetic fields (the type emitted by power lines and electrical devices) for either 2 hours once or 2 hours daily for 2 weeks. They found that long-term exposure reduced depression-like behavior in the mice, while short-term exposure interfered with antidepressant medications. This suggests that chronic EMF exposure may alter brain chemistry and affect how psychiatric medications work.
Ma Q et al. · 2016
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.
Madjid Ansari A et al. · 2016
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.

Scientists exposed cells to 50 Hz magnetic fields from power lines at levels above 50 microtesla and found genetic damage patterns similar to Alzheimer's patients. The exposure caused chromosome instability in cells, suggesting a possible biological link between power line magnetic fields and Alzheimer's disease development.

Researchers exposed rats to 10 Hz magnetic fields for 15 days to study brain chemistry effects. Three hours of daily exposure decreased serotonin breakdown products in the brain's mood-regulating region, while one hour had no effect. This suggests magnetic fields can alter brain chemistry linked to mood.
Deshmukh PS et al. · 2016
Researchers exposed rats to cell phone radiation (900 MHz) at extremely low levels for 90 days. The rats developed impaired learning and memory, elevated stress proteins, and DNA damage in brain cells at radiation levels thousands of times below current safety standards.

Researchers exposed adult frogs to cell phone radiation (900 MHz) for 8 hours daily over 5 weeks, then examined their offspring. Exposed parents produced 3-5 times more abnormal and dead embryos than unexposed pairs, demonstrating that radiofrequency radiation can damage reproductive cells and harm the next generation.

Researchers exposed mouse embryonic cells to 1,800 MHz radiofrequency radiation (similar to cell phone signals) at high power levels for 1-12 hours and found it initially caused DNA breaks. However, after prolonged exposure, the cells' DNA repair systems became so active that DNA damage dropped below normal background levels - a phenomenon called hormesis where low doses of a harmful substance trigger beneficial protective responses.
Çeliker M et al. · 2016
Turkish researchers exposed rats to cell phone radiation at 2100 MHz for 30 days to study effects on hearing. While the rats' hearing tests showed no changes, microscopic examination revealed significant damage to brain cells in the auditory system, including increased cell death and degeneration. This suggests that cell phone radiation may harm the hearing system in ways that don't show up immediately in standard hearing tests.
İkinci A et al. · 2016
Researchers exposed young male rats to 900 MHz electromagnetic fields (similar to cell phone radiation) for one hour daily during adolescence and examined their spinal cords. They found significant damage including deterioration of the protective myelin sheaths around nerve fibers, tissue atrophy, and increased oxidative stress markers. This suggests that RF radiation exposure during critical developmental periods may harm the nervous system's structure and function.
Mugunthan N et al. · 2016
Researchers exposed mice to radiation from 2G mobile phones (900-1800 MHz) for 48 minutes daily over 1-6 months and examined brain tissue under microscopes. They found significant damage to the hippocampus, the brain region crucial for memory and learning, including reduced numbers of neurons and smaller cell nuclei. This suggests that prolonged mobile phone radiation exposure may harm brain cells in ways that could affect cognitive function.
Odacı E et al. · 2016
Pregnant rats exposed to cell phone-frequency radiation (900-MHz) for one hour daily produced offspring with significantly fewer brain cells in the cerebellum, the region controlling movement and coordination. The brain damage persisted into young adulthood, suggesting prenatal EMF exposure may harm developing brains.
Hidisoglu E et al. · 2016
Researchers exposed rats to cell phone-frequency radiation for 1 week versus 10 weeks. Short exposure improved brain function and antioxidant protection, while long exposure caused slower brain responses and oxidative damage. This shows EMF effects depend critically on exposure duration.
Kerimoğlu G, Aslan A, Baş O, Çolakoğlu S, Odacı E. · 2016
Researchers exposed young rats to cell phone frequency radiation (900 MHz) for just one hour daily throughout their adolescent development and found significant damage to their spinal cords. The exposed rats showed structural abnormalities, increased cell death, and biochemical markers of oxidative stress in spinal cord tissue. This suggests that even limited daily exposure to radiofrequency radiation during critical developmental periods can harm nervous system tissue.
Kerimoğlu G et al. · 2016
Researchers exposed young rats to 900 MHz radiation (cell phone frequencies) daily during adolescence. Brain examination revealed significant hippocampus damage including dead neurons, fewer healthy brain cells, and oxidative stress markers. This suggests cell phone radiation during development may cause lasting memory and learning problems.
Rostami A et al. · 2016
Researchers exposed male rats to extremely low frequency electromagnetic fields (ELF-EMF) at 3 Hz and 60 Hz for several days and measured effects on brain activity and behavior. They found that both frequencies significantly reduced the rats' movement and decreased the firing rate of neurons in the locus coeruleus, a brain region important for arousal and attention. The study also detected widespread changes in brain proteins, suggesting that ELF-EMF exposure can alter brain function at multiple biological levels.
Akdag MZ et al. · 2016
Turkish researchers exposed rats to 2.4 GHz Wi-Fi radiation for over a year to test whether it causes DNA damage in various organs. While they found no significant DNA damage in brain, kidney, liver, or skin tissue, they discovered significant genetic damage specifically in testicular tissue. This suggests that reproductive organs may be particularly vulnerable to long-term Wi-Fi exposure.
Safian F et al. · 2016
Iranian researchers exposed mouse embryos to cell phone radiation (900-1800 MHz) for 30 minutes daily during their first four days of development. While the embryos still developed normally to the blastocyst stage, they showed significantly higher cell death rates and reduced cell viability compared to unexposed embryos. This suggests that cell phone radiation may damage developing embryos even when overall development appears normal.
Reale M et al. · 2016
Researchers exposed human brain cells to extremely low frequency electromagnetic fields (the type from power lines) for up to 48 hours to see if it would cause neurological damage. They found no significant harmful effects on the cells' ability to manage oxidative stress or inflammation, though there were minor changes in serotonin metabolism. The study suggests that ELF-EMF exposure at these levels is unlikely to contribute to neurodegenerative diseases.
