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 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 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 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.

Ukrainian researchers exposed developing quail embryos to low-level cell phone radiation (1800 MHz) at power levels typical of smartphone use. The radiation caused significant DNA damage, doubled the production of harmful molecules that damage cells, and nearly doubled embryo death rates. This demonstrates that even very low levels of wireless radiation can cause genetic damage in developing organisms.

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 studied how static magnetic fields affect cancer treatment with doxorubicin (a common chemotherapy drug). They found that magnetic fields at 10 millitesla enhanced the drug's cancer-killing effects by increasing harmful molecules called reactive oxygen species (ROS) in cancer cells. This could potentially allow doctors to use lower doses of chemotherapy while maintaining effectiveness, reducing side effects for patients.

Researchers exposed rats to static magnetic fields for 50 days and found significant changes in brain enzyme activity, including increased levels of enzymes that control nerve signaling and cellular energy. The magnetic field exposure also increased oxidative stress markers and decreased protective antioxidant activity in brain tissue. These findings suggest that chronic magnetic field exposure can alter fundamental brain chemistry in ways that might affect neurological health.

Coballase-Urrutia E et al. · 2018
Researchers exposed stressed laboratory animals to weak static magnetic fields (0.8 mT) for varying durations over 5 days and measured markers of cellular damage called oxidative stress. They found that magnetic field exposure significantly reduced harmful oxidative stress markers while boosting the body's natural antioxidant defenses. The protective effects were time-dependent, suggesting that controlled magnetic field exposure might help the body cope with stress-related cellular damage.

Researchers exposed brain cells to cell phone radiation (1950 MHz) for 2 hours daily over 3 days to see if it affected amyloid-beta processing, which is linked to Alzheimer's disease. They found no significant changes in the proteins that create these brain plaques. However, the researchers noted that longer-term exposure might produce different results than their short 3-day study.
Haas AJ et al. · 2017
French researchers exposed nerve cells to 60.4 GHz millimeter wave radiation (the type used in 5G and some wireless systems) for 24 hours to see if it affected dopamine, a key brain chemical involved in movement and mood. They found no significant changes in dopamine production or processing, with only a slight increase in one dopamine byproduct that they attributed to heating effects. This suggests that millimeter wave exposure at these levels doesn't disrupt basic nerve cell function related to dopamine.

Researchers exposed pregnant mice and their offspring to cell phone radiation at 900 and 1800 MHz frequencies, then examined how this affected genes related to cell death and DNA repair in the brain's cerebellum. They found that the radiation did not trigger cell death pathways but did alter expression of genes involved in DNA repair. The authors concluded that while cell phone radiation may cause some cellular changes, the brain appears capable of repairing any damage through normal cellular mechanisms.

Researchers exposed pregnant rats to mobile phone radiation (900 MHz) for 20 days and examined their offspring's livers 60 days after birth. The exposed animals showed significant liver damage including increased oxidative stress, elevated liver enzymes indicating injury, and visible tissue damage under the microscope. This study demonstrates that EMF exposure during pregnancy can cause lasting liver problems in offspring that persist into adulthood.

Researchers exposed two types of bacteria (Listeria and E. coli) to radiofrequency radiation from cell phones (900 MHz) and Wi-Fi routers (2.4 GHz) to see if it affected how well antibiotics worked against them. They found that RF exposure made these disease-causing bacteria more resistant to antibiotics, meaning the medications became less effective at killing them. This could have serious implications for treating infections, as it suggests our wireless devices might be contributing to the growing problem of antibiotic-resistant bacteria.

Iranian researchers exposed rats to 915 MHz radiofrequency radiation (similar to microwave ovens) for 4 hours daily over one week, then tested whether this 'primed' their liver cells to better handle a subsequent dose of gamma radiation. They found that low-power RF exposure increased antioxidant enzymes like glutathione, which helped protect liver tissue from oxidative damage when the rats were later exposed to harmful gamma radiation.

Researchers exposed yeast cells to radiofrequency radiation (2.0 GHz) and extremely low frequency fields (50 Hz) to study effects on protein misfolding. They found that both types of electromagnetic fields increased the formation and spread of prions (misfolded proteins linked to neurodegenerative diseases) in a dose-dependent manner. This suggests EMF exposure may contribute to protein misfolding disorders through oxidative stress mechanisms.
