Researchers exposed yeast cells to both 50 Hz magnetic fields and 1800 MHz radiofrequency radiation to see if electromagnetic fields could change gene activity. They found that magnetic fields caused no confirmed gene changes, while radiofrequency exposure affected only 2-5 genes out of thousands tested. This suggests that EMF effects on basic cellular processes may be more limited than some studies indicate.

Researchers exposed people to strong 60 Hz magnetic fields (like power lines emit) for one hour. The exposure impaired balance and increased hand tremor, even though brain waves stayed normal. This shows power-frequency fields can affect movement control in subtle ways.

Italian researchers exposed pregnant mice to WiFi signals (2.45 GHz) at high levels for 2 hours daily throughout pregnancy to study effects on their offspring's immune system development. They found no detrimental effects on T cell development, immune cell counts, or immune function in the offspring at either 5 weeks or 26 weeks of age. This suggests that prenatal WiFi exposure may not harm developing immune systems, though the study used exposure levels much higher than typical human exposure.

Researchers exposed human breast tissue cells to cell phone frequencies (837 MHz and 1950 MHz) at high power levels for 2 hours to test whether radiofrequency radiation causes oxidative stress, a type of cellular damage linked to disease. The study found no signs of oxidative stress in the cells, even when exposed to both frequencies simultaneously. This suggests that under these specific laboratory conditions, RF radiation did not trigger the cellular damage processes that scientists look for as early warning signs of health effects.

Researchers exposed immune cells (monocytes) to 2450 MHz microwave radiation - the same frequency used in microwave ovens and Wi-Fi - and found it suppressed their normal inflammatory response. When these cells were stimulated to trigger inflammation, microwave exposure reduced their production of NFκB, a key protein that regulates immune function. This suggests microwave radiation can interfere with your immune system's ability to respond properly to threats.

Researchers exposed rats to extremely low-frequency electric fields (the type generated by power lines) for one hour daily over two weeks. The exposed animals showed significant damage to brain and retinal tissue, including increased oxidative stress (cellular damage from free radicals) and disrupted visual processing. This suggests that even brief daily exposures to electric fields can harm the nervous system and vision.

Researchers exposed different head areas to low-frequency magnetic fields and measured brain waves. The magnetic fields altered brain activity patterns across multiple regions, not just where exposed, showing that localized magnetic field exposure can affect broader brain function than previously expected.

Korean researchers exposed mouse and human cells to 60 Hz magnetic fields (the same frequency used in electrical power systems) for 4 hours to see if this would cause DNA damage, either alone or when combined with known cancer-causing agents like radiation. They found no DNA damage from the magnetic field exposure, even when combined with other harmful substances that normally cause genetic damage.

Researchers exposed mouse cells to 60 Hz magnetic fields (the type from power lines) to see if this could trigger cellular transformation into cancer-like cells. They tested the magnetic field alone and combined with known cancer-causing agents like radiation. The study found no evidence that the magnetic field exposure caused cell transformation or enhanced the cancer-causing effects of other agents.

Researchers exposed young and older gerbils to 50 Hz magnetic fields (power line frequency) for seven days. Both age groups showed significant changes in movement and activity levels that persisted for days after exposure ended, indicating brain motor centers are sensitive to electromagnetic fields.

Researchers exposed young and older gerbils to power-line frequency magnetic fields for seven days. Both age groups showed significant behavioral changes, with younger animals becoming more active. The effects persisted three days after exposure ended, indicating potential lasting impacts on brain function.

Researchers exposed cartilage cells from arthritis patients to 100-Hz electromagnetic fields to test potential therapeutic effects. They found that EMF exposure enhanced cell growth without causing DNA damage, oxidative stress, or cell death. This suggests electromagnetic fields might offer a non-drug treatment option for osteoarthritis.

Swedish researchers exposed land snails to cell phone radiation at 1900 MHz (the same frequency used by many mobile phones) for one hour, then tested their response to painful heat. The radiation-exposed snails showed significantly reduced sensitivity to pain compared to unexposed snails, suggesting the electromagnetic fields had an anesthetic-like effect on their nervous systems.

Researchers exposed rats to 50 Hz magnetic fields (the same frequency as household electrical wiring) for 21 days and measured their anxiety levels using standard behavioral tests. The exposed rats showed significantly higher anxiety and stress-related behaviors compared to unexposed rats, spending much less time in open, exposed areas of test mazes. This suggests that prolonged exposure to power-frequency magnetic fields may increase stress responses in the brain.

Researchers exposed land snails to cell phone radiation at 1900 MHz for one hour and tested their response to heat-induced pain. The exposed snails showed reduced sensitivity to thermal pain compared to unexposed controls, suggesting the radiofrequency radiation acted as a pain reliever. This finding indicates that non-thermal levels of cell phone radiation can alter nervous system responses in living organisms.

Researchers measured radiofrequency radiation from cell towers, radio, and TV stations across 65 locations in Palestine. FM radio stations produced the highest exposure levels at 62% of total radiation. All measurements remained well below international safety limits, providing important baseline data for urban RF exposure.

Researchers exposed pregnant mice to power line frequency electromagnetic fields for seven days, then tested their babies' motor skills. Mice exposed in the womb showed significant learning deficits compared to unexposed mice, suggesting developing brains are particularly vulnerable to EMF during pregnancy.
Vignola MB et al. · 2012
Researchers exposed rats with muscle inflammation to pulsed electromagnetic fields (PEMF) at 20 mT and 50 Hz for 30 minutes daily over 8 days. The PEMF treatment significantly reduced inflammatory markers and oxidative stress indicators while promoting muscle healing. This suggests that specific electromagnetic field exposures may have therapeutic benefits for muscle injuries, though the high field strength used is much greater than typical environmental exposures.

Researchers analyzed the health records of US embassy staff in Moscow who were exposed to microwave radiation (2.5-4.0 GHz) from 1953-1976, comparing them to staff at other Eastern European embassies. The study found no adverse health effects from the microwave exposure, which was at levels similar to or higher than current cell phone tower emissions. This Cold War incident provides unique long-term data on radiofrequency exposure effects in humans.

Researchers exposed pregnant mice to radiofrequency radiation from cell phones (at levels similar to human exposure) throughout pregnancy and then tested the offspring's behavior and brain function. The exposed mice showed hyperactivity and memory problems as adults, along with measurable changes in brain cell communication in the prefrontal cortex. This study provides the first direct experimental evidence that prenatal cell phone radiation exposure can alter brain development and behavior.
Liu YX et al. · 2012
Researchers exposed rat brain support cells to cell phone radiation at 1950 MHz for 48 hours. The radiation damaged cellular powerhouses and triggered cell death through a specific pathway, though it didn't promote tumors. This suggests prolonged exposure may harm healthy brain cells.
Lu Y et al. · 2012
Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 3 hours daily over 30 days at very low power levels. The radiation caused significant memory and learning problems, and the rats' brain cells had trouble absorbing glucose, which is essential for brain function. However, when researchers gave the rats extra glucose, it reversed the memory problems.
