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 studied how weak magnetic fields affect stem cells by examining tissue regeneration in planarians (flatworms that can regrow body parts). They found that depending on the magnetic field strength, these fields could either increase or decrease new tissue formation by altering stem cell activity and cellular stress responses. This suggests weak magnetic fields might be developed as therapeutic tools to control cell growth and healing processes.

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 baker's yeast (Saccharomyces cerevisiae) to a strong static magnetic field of 250 millitesla for 6 to 9 hours to study biological effects. They found the magnetic field initially reduced yeast growth and survival, then triggered oxidative stress - a harmful cellular condition where damaging molecules overwhelm the cell's natural defenses. The study demonstrated that even simple organisms like yeast respond to magnetic field exposure with measurable biological changes.

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 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.
Cichon N et al. · 2018
Researchers studied 48 stroke patients who received either standard physical therapy alone or physical therapy plus extremely low frequency electromagnetic field (ELF-EMF) treatment. They found that patients receiving ELF-EMF therapy showed significantly increased activity in genes that produce antioxidant enzymes - the body's natural defense system against cellular damage. This suggests ELF-EMF therapy may help stroke patients recover by boosting their cells' ability to protect themselves from harmful oxidative stress.

Polish researchers studied whether extremely low frequency electromagnetic fields could help stroke patients recover brain function during rehabilitation. They found that patients receiving EMF therapy alongside standard rehabilitation showed significantly higher levels of brain growth factors that promote healing and scored better on cognitive and functional recovery tests. This suggests EMF therapy may enhance the brain's natural ability to rewire itself after stroke damage.
Bukia N et al. · 2018
Researchers studied whether low-frequency electromagnetic fields could reduce seizures in epileptic rats by affecting brain chemical systems. They found that acoustic-range electromagnetic exposure decreased seizure activity by changing how neurotransmitters (brain chemicals like GABA and glutamate) function in the brain. This suggests electromagnetic fields might influence seizure disorders through specific brain chemistry pathways.

Researchers exposed zebrafish embryos to 100 MHz radiofrequency radiation (similar to FM radio frequencies) to study developmental effects. They found the radiation triggered oxidative stress, slowed growth, and activated cellular damage repair mechanisms during critical early development stages. This study demonstrates that EMF radiation can cause measurable biological effects beyond just heating tissue, providing important evidence for non-thermal health impacts.

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.
López-Furelos A et al. · 2018
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 cell phone frequencies (900 and 1800 MHz) for one hour daily, five days a week for an entire year, then examined brain tissue for damage. They found significant cellular damage including cell death, oxidative stress, and disrupted calcium channels in the hippocampus (memory center) and nerve tissues. The higher frequency (1800 MHz) caused more severe damage than the lower frequency, suggesting a dose-response relationship.

Researchers exposed human brain cancer cells to alternating magnetic fields (280 kHz frequency) for 30 minutes while treating them with an anti-cancer compound called Compound C. The magnetic field exposure significantly enhanced the cancer-killing effects of the drug, causing more cancer cells to die and preventing them from multiplying. This suggests that magnetic fields might be used to make cancer treatments more effective while potentially allowing lower drug doses.

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.

Researchers exposed turkeys to 50 Hz magnetic fields (the type from power lines) for three weeks and found it disrupted their stress response system by reducing a key cellular signaling pathway called beta-adrenoceptor function. The birds' systems returned to normal after five weeks without exposure, suggesting the effects were reversible. This matters because it shows even relatively low-level magnetic field exposure can alter fundamental biological processes in living animals.
