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 rats to 50 Hz magnetic fields (the same frequency as power lines) for 2 hours daily over 15 days and found the fields produced pain relief (analgesia). They discovered this pain-blocking effect works through serotonin receptors in the brain - the same chemical system involved in mood and sleep. The study shows that extremely low frequency magnetic fields can directly alter brain chemistry and pain perception.

Researchers exposed participants to Earth-strength magnetic fields while monitoring their brain activity with EEG. They discovered that specific magnetic field rotations caused measurable changes in brain waves (alpha oscillations), but only when the field was oriented as it naturally occurs in the Northern Hemisphere. This suggests humans possess an unconscious magnetic sensing ability similar to migratory animals.

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.

Spanish researchers exposed immune cells (macrophages) to radio frequency radiation at cell phone frequencies (900 MHz and 2450 MHz) for up to 72 hours. They found that the radiation significantly impaired the cells' ability to fight infections and triggered inflammatory responses, with combined frequencies causing more damage than single frequencies. This suggests that everyday exposure to multiple wireless signals simultaneously may compromise immune function.

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.

Researchers exposed lab-grown nerve cells with ALS-related genetic mutations to 50 Hz magnetic fields (the same frequency as power lines) for up to 72 hours. They found that while the magnetic field didn't kill cells or increase oxidative stress, it disrupted iron metabolism genes specifically in cells with the SOD1G93A mutation linked to familial ALS. This suggests that power frequency magnetic fields may interfere with cellular iron regulation in genetically susceptible individuals.

Researchers exposed tiny worms (C. elegans) to 50-Hz magnetic fields at 3 milliTesla from egg to larval stage and found significant disruptions in cellular energy production and inflammation pathways. The magnetic field exposure caused oxidative stress (cellular damage from free radicals), impaired the worms' energy-producing machinery, and increased inflammatory compounds. This matters because it demonstrates that power-frequency magnetic fields can disrupt fundamental biological processes at the cellular level.

Researchers calculated how much radiofrequency energy from smart meters gets absorbed by human bodies. Children absorbed the most energy, especially when within 15 centimeters of 2.4 GHz meters. Though levels stayed below safety limits, the study confirms smart meters cause measurable energy absorption in tissue.

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.

Researchers exposed 14 healthy volunteers to 20 Hz magnetic fields generated by rotating permanent magnets for 15 minutes, then measured brain activity in the motor cortex (the brain region controlling movement). They found that this magnetic field exposure significantly reduced motor cortex excitability, meaning the brain region became less responsive to stimulation. This demonstrates that even brief exposure to rotating magnetic fields can measurably alter brain function.

Researchers exposed human brain cells (neuroblastoma cells) to 50 Hz electromagnetic fields at 0.5 mT for different time patterns and measured changes in antioxidant gene expression. They found that EMF exposure altered the activity of genes responsible for protecting cells from damage, with different exposure patterns producing different effects. This suggests that even brief EMF exposures can disrupt the cellular machinery that defends against oxidative stress.

Researchers exposed human brain cells and mouse neurons to 50-Hz magnetic fields (the type from power lines) at 1 milliTesla and found significant changes in gene regulation. The magnetic fields altered microRNAs (small molecules that control gene expression) and increased production of alpha-synuclein, a protein linked to Parkinson's disease. This suggests that power-frequency magnetic fields may disrupt normal brain cell function through epigenetic changes that could predispose neurons to degeneration.

Scientists tested whether 50 Hz magnetic fields affect how cancer drugs work on different cell types. The magnetic field protected nerve cells from chemotherapy toxicity by boosting antioxidants, but didn't protect breast cancer cells. This shows EMF can alter medical treatment effectiveness differently across cell types.

Researchers exposed rats to 2450 MHz electromagnetic radiation (the frequency used by WiFi and microwave ovens) for one hour daily over 28 days and found significant cognitive impairment. The radiation damaged brain cell powerhouses called mitochondria, triggered cell death pathways, and disrupted the brain's chemical messaging system. This suggests that chronic exposure to common wireless frequencies may harm memory and thinking abilities through multiple biological mechanisms.
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.

Researchers tested whether transcranial magnetic stimulation (TMS) using 60 Hz magnetic fields at 0.7 mT could help treat an animal model of multiple sclerosis. They found that TMS reduced brain inflammation and oxidative stress (cellular damage from unstable molecules) more effectively than standard pharmaceutical treatments. This suggests magnetic field therapy might have protective effects on the nervous system.
