Researchers exposed bone cancer cells to extremely low frequency electromagnetic fields (ELF-EMF) at 50 Hz and 1 milliTesla for up to 3 hours. They found the EMF exposure triggered cancer cell death (apoptosis) by increasing oxidative stress and activating specific cellular pathways. This suggests ELF-EMF might have potential therapeutic applications against bone cancer, though this was only tested in laboratory cell cultures, not living organisms.

Italian researchers exposed leukemia cells to extremely low frequency electromagnetic fields (the type emitted by power lines and household appliances) for 24 hours at 50 Hz. They found significant changes in three key cellular enzymes that control oxidative stress and cellular metabolism. These enzyme disruptions could help explain how EMF exposure might contribute to health problems at the cellular level.

Researchers exposed rats to strong magnetic fields for one hour daily over five days. The exposure increased oxidative stress markers by 25-34% in kidney tissue but not muscle. Selenium and vitamin E supplements prevented this kidney damage, suggesting antioxidants may protect against magnetic field effects.

Researchers exposed rats to 60 Hz magnetic fields (the same frequency as household electricity) for 2-5 days and measured brain chemicals called neurotransmitters. They found significant changes in key brain chemicals including dopamine, serotonin, and norepinephrine across multiple brain regions. These neurotransmitters control mood, movement, and cognitive function, suggesting that magnetic field exposure can alter brain chemistry.

Researchers exposed rats and brain cells to microwave radiation at 30 mW/cm² and found significant damage to brain structures responsible for learning and memory. The exposure disrupted the delicate balance of brain chemicals and damaged the connections between brain cells (synapses). This suggests that microwave radiation can interfere with the brain's ability to form new memories and learn.

Researchers exposed rats to 1800 MHz radiofrequency radiation (the same frequency used in cell phones) for 15 minutes, five times daily, and measured oxidative damage in their organs. They found increased lipid peroxidation (cellular damage from oxidation) in the brain, blood, and kidneys of exposed animals. This suggests that repeated cell phone-frequency radiation exposure may cause oxidative stress damage to vital organs.

Researchers exposed young rats to 21-kHz magnetic fields (similar to frequencies used in induction heating and some wireless charging) for one hour daily over two weeks to test effects on blood and immune system function. The study found no significant changes in immune cell activity, blood cell counts, or other immune markers, with only a minor phosphorus level change that remained within normal ranges. This suggests that short-term exposure to these intermediate-frequency magnetic fields may not substantially impact immune function in developing animals.

Brazilian researchers examined cells from the mouths of 45 mobile phone users to look for DNA damage and cell death markers. They found no differences in most cellular damage markers between light, moderate, and heavy phone users (more than 5 hours per week). However, heavy users showed significantly more 'broken egg' structures in their cells, which may indicate gene amplification problems.

Researchers exposed aquatic plants to 2 GHz radio frequency radiation (similar to cell phone signals) for one hour and measured ultra-precise changes in how the plants grew. The radiation significantly altered the plants' natural growth patterns by 51%, and these changes persisted for at least 2.5 hours after exposure ended. This demonstrates that RF radiation can affect living organisms through non-thermal mechanisms, even in plants.

Korean researchers measured radiofrequency (RF) radiation levels at 1,260 locations across densely populated areas to see how much wireless radiation people are actually exposed to in their daily lives. They found that even in areas with many cell towers and wireless devices, the total RF exposure was extremely low - only about 7% of international safety guidelines. This suggests that current wireless infrastructure in urban areas produces RF levels well below established safety limits.

Researchers exposed nerve cells (PC12 cells) to 50 Hz magnetic fields at extremely high levels - up to 1000 microteslas, which is 10,000 times stronger than typical background exposure. They tested both healthy cells and chemically-stressed cells that were more vulnerable to damage. The study found no toxic effects on the nerve cells' calcium balance, oxidative stress levels, or cell membrane integrity, even at these extraordinarily high exposure levels.
Furtado-Filho OV et al. · 2014
Brazilian researchers exposed young rats to cell phone-level radiation (950 MHz) for 30 minutes daily, starting before birth and continuing up to 30 days after birth. They found no evidence of oxidative stress or DNA damage in most age groups, though 30-day-old rats showed some genetic changes and newborns had altered fatty acid levels in their livers. The study suggests that developing animals may be more resilient to short-term RF radiation exposure than previously thought.
Kang KA et al. · 2014
Researchers exposed neuronal brain cells to combined cell phone radiation (CDMA and WCDMA signals) for 2 hours to measure whether this caused oxidative stress, a type of cellular damage linked to various health problems. The study found no increase in reactive oxygen species (cellular damage markers) in any of the three types of brain cells tested, even when combined with known oxidative stress agents.

Turkish researchers exposed rats to Wi-Fi radiation (2.45 GHz) for one hour daily over 30 days and found it caused oxidative stress in the eye lens, similar to cellular damage from aging or toxins. When rats were given melatonin supplements, the antioxidant significantly reduced this Wi-Fi-induced damage. This suggests that common Wi-Fi exposure may harm delicate eye tissues, but natural protective compounds could help defend against such effects.

Researchers exposed male rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) for 1, 2, or 4 hours daily over 30 days. Rats exposed for 4 hours daily showed significantly decreased testosterone levels and disrupted reproductive hormones compared to unexposed rats. This suggests that prolonged RF exposure may interfere with male fertility and reproductive function.
Geronikolou S et al. · 2014
Researchers exposed fruit flies (Drosophila) to radiation from both mobile phones (900 MHz) and cordless phones (1880 MHz) to study reproductive effects. They found that mobile phone radiation significantly reduced egg laying in the second generation of flies, while cordless phone radiation showed only limited effects. The study suggests that lower frequency radiation may cause stronger biological impacts.

Researchers compared blood markers between 120 heavy mobile phone users (IT professionals) and 102 light users to see if phone radiation triggers stress responses in the body. They found significantly elevated levels of heat shock protein 70 (HSP70) and C-reactive protein (CRP) in heavy users, indicating cellular stress and inflammation. This suggests that frequent mobile phone use may activate biological stress pathways that could potentially impact health over time.

Researchers exposed male rats to extremely low frequency electromagnetic fields at 1 Hz and 5 Hz to study effects on stress hormones and behavior. They found that these exposures altered stress hormone levels (increasing ACTH while decreasing noradrenaline) and changed glucose metabolism differently depending on the frequency used. The study demonstrates that even very low frequency EMF exposures can disrupt the body's stress response system in measurable ways.

Researchers exposed rat brain cells to extremely low-frequency electromagnetic fields (ELF-EMF) for 60 minutes and found it dramatically increased sodium ion currents by 62.5%, which can disrupt normal brain cell function. However, when they treated the cells with melatonin (a hormone naturally produced by your body), it protected against these harmful effects. This suggests melatonin may serve as a natural defense mechanism against EMF-induced brain cell damage.

Researchers exposed rats to Wi-Fi radiation (2.45 GHz) for one hour daily over 30 days to study effects on eye lens health. They found that Wi-Fi exposure caused oxidative stress in the lens tissue, indicated by increased harmful byproducts and decreased protective antioxidant activity. However, when rats were given melatonin supplements, these negative effects were significantly reduced, suggesting melatonin may help protect eye tissue from Wi-Fi-related damage.
Ragy MM. · 2014
Researchers exposed rats to cell phone radiation (900 MHz) for one hour daily over 60 days and measured damage in the brain, liver, and kidneys. They found significant increases in cellular damage markers and decreases in the body's natural antioxidant defenses across all three organs. The good news: when exposure stopped for 30 days, the damage reversed, suggesting the effects may be recoverable.
Hässig M et al. · 2014
Swiss researchers exposed dairy cows to radiofrequency radiation from cell tower base stations and measured changes in their blood enzymes that help protect cells from damage. They found that the radiation altered these protective enzyme systems in some cows but not others, with individual animals showing different sensitivity patterns. This suggests that RF radiation from cell towers can disrupt cellular protective mechanisms, though sensitivity varies significantly between individuals.

Researchers exposed rat brain cells to extremely low frequency electromagnetic fields (ELF-EMF) for one hour and found that this exposure increased sodium channel activity in the cells by 62.5%. However, when the hormone melatonin was present, it prevented this electromagnetic field-induced change in brain cell function. This suggests melatonin may offer some protection against certain neurological effects of EMF exposure.

Computer modeling revealed that extremely low-frequency magnetic fields from power lines and appliances disrupt brain cell firing patterns. The disruption increases with stronger fields and occurs through resonance when field frequencies match natural brain rhythms, explaining how weak magnetic fields influence brain function.

Researchers exposed rat brain cells to extremely low-frequency electromagnetic fields (like those from power lines) and found the EMF exposure significantly increased electrical activity in neurons by 62.5%. However, when they treated the cells with melatonin, it protected against these EMF-induced changes. This suggests melatonin might help shield brain cells from electromagnetic field effects.
