Researchers exposed pregnant rats to 900 MHz cell phone radiation for one hour daily and examined the immune organs (spleen and thymus) of their male offspring at 21 days old. The prenatal radiation exposure caused significant oxidative damage and structural abnormalities in these critical immune system organs. This suggests that EMF exposure during pregnancy may compromise immune system development in offspring.

Male rats exposed to cell phone radiation (900 MHz) for one hour daily showed damaged sperm quality, reduced sperm count, and abnormal testicular tissue after seven days. This research suggests that cell phone radiation may harm male fertility in mammals.
Barteri M et al. · 2015
Researchers exposed two important enzymes (lactoperoxidase and horseradish peroxidase) to 900 MHz radiofrequency radiation and found that the exposure caused structural changes to the enzymes' active sites. These changes affected how the enzymes functioned and how they formed free radicals. This matters because these same types of enzymes play crucial roles in human cellular processes.

Chinese researchers used powerful magnetic fields to simulate weightlessness conditions and study how this affects bone-destroying cells called osteoclasts. They found that simulated microgravity enhanced the formation and bone-eating activity of these cells, while the magnetic field itself had the opposite effect. This research helps explain why astronauts lose bone density in space and provides insights into magnetic field effects on bone health.

Researchers exposed neuroblastoma cells (a type of brain cancer cell) to pulsed electromagnetic fields for short periods over several weeks, then tested how well the cells handled oxidative stress (cellular damage from harmful molecules). They found that the EMF pre-exposure increased the cells' natural antioxidant defenses and made them more resistant to damage from hydrogen peroxide, suggesting that certain EMF exposures might help cells protect themselves against harmful oxidation.

Researchers exposed young rats to cell phone-frequency radiation (900 MHz) for one hour daily over 30 days. Brain scans revealed significant damage to hippocampus neurons responsible for learning and memory, with fewer healthy brain cells compared to unexposed rats, suggesting potential developmental harm.
Özgür A et al. · 2015
Researchers exposed rats to mobile phone electromagnetic waves for 30 days and examined their auditory systems. The exposed rats showed significant neuronal damage in the brain regions that process hearing, including cell death and tissue swelling. While hearing function tests appeared normal, the microscopic damage suggests that chronic EMF exposure may harm the auditory processing centers in the brain.

Researchers exposed rats and nerve cells to microwave radiation at levels similar to wireless devices. The exposure damaged brain synapses (nerve cell connections) and disrupted brain chemicals essential for memory formation, suggesting microwave radiation may impair learning and memory abilities.
Wang C et al. · 2015
Researchers exposed mouse bone marrow stem cells to 2.856 GHz microwave radiation. While cells remained healthy and continued dividing normally, the radiation reduced expression of genes crucial for bone formation, suggesting microwaves can affect cellular function even without visible damage.
Wang D et al. · 2015
Researchers exposed sperm samples from 97 healthy men to cell phone radiation (1950 MHz frequency) for 3 hours at levels similar to what phones emit during calls. The radiation significantly reduced sperm movement and survival rates while increasing cell death and structural defects in sperm heads. This suggests that cell phone radiation can directly damage sperm quality, which could impact male fertility.
Tang J et al. · 2015
Researchers exposed rats to cell phone radiation (900 MHz) for 28 days and found it damaged the blood-brain barrier and impaired memory. The radiation caused brain cells to swell and allowed harmful substances to leak into brain tissue, providing direct evidence of cognitive damage.
Ozgur E et al. · 2015
Scientists exposed guinea pigs to cell phone radiation (900 MHz) for seven days and found it significantly reduced SOD, a protective antioxidant enzyme in liver tissue. Surprisingly, two common antioxidant supplements caused cellular damage when used alone, showing radiation's complex effects on cellular protection.

Researchers exposed young rats to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for one hour daily over four weeks and tested their learning and memory abilities. The exposed rats showed decreased learning abilities and poorer memory retention, especially when tested 48 hours after training. Brain tissue examination revealed structural damage to the hippocampus, the brain region critical for memory and spatial navigation.

Researchers exposed rats to pulsed microwave radiation and found significant damage to the sinoatrial node, the heart's natural pacemaker. At moderate to high power levels, the radiation caused cell swelling, structural damage, and permanent scarring that lasted up to 12 months, potentially affecting heart rhythm control.

Researchers exposed corn seedlings to cell phone radiation (1800 MHz) for different time periods and found that 4 hours of exposure significantly stunted growth and disrupted the plants' sugar metabolism. The radiation caused a 23% reduction in shoot growth and altered key enzymes responsible for breaking down starches and sugars that plants need for energy. This demonstrates that radiofrequency radiation can interfere with fundamental biological processes even in plants.
Holovská K et al. · 2015
Researchers exposed rats to 2.45 GHz microwave radiation (the same frequency used by WiFi and microwave ovens) for 3 hours daily over 3 weeks at power levels of 2.8 mW/cm². They found liver damage including inflammation, blood vessel dilation, and cellular changes including fat accumulation and dying liver cells. This suggests that chronic exposure to common microwave frequencies may harm liver function.
Grémiaux A et al. · 2015
French researchers exposed rose bushes to 900MHz electromagnetic fields (the same frequency used by cell phones) and tracked their growth for over a month. They found that EMF exposure significantly reduced growth by 45% in newly developing shoots, but only when plants were exposed at their earliest development stage. The effect occurred at extremely low power levels, ruling out heating as the cause.
Furtado-Filho OV et al. · 2015
Brazilian researchers exposed pregnant rats and their newborns to cell phone frequency radiation (950 MHz) for 30 minutes daily throughout pregnancy and after birth. They found that 6-day-old exposed rats showed protein damage specifically in the right side of their brain, plus lower blood sugar levels. Newborn rats showed no effects, suggesting developing brains become more vulnerable to EMF damage as they mature.
Eris AH et al. · 2015
Researchers exposed rats to cell phone-level radiofrequency radiation (900 MHz) for just 45 minutes and measured changes in brain chemicals. They found that this brief exposure significantly increased blood serotonin levels, a neurotransmitter that affects mood and cognitive function. The researchers note this serotonin increase could potentially impact learning and memory abilities.
Djordjevic B et al. · 2015
Serbian researchers exposed rats to 900 MHz microwave radiation (similar to cell phone frequencies) for 4 hours daily over 20-60 days and found significant liver damage, including increased oxidative stress and cellular damage markers. When rats were also given melatonin supplements, the treatment partially protected against some of the radiation-induced liver damage. This suggests that microwave radiation can harm liver function, but natural antioxidants like melatonin may offer some protection.
Dasdag S et al. · 2015
Researchers exposed rats to cell phone radiation (900 MHz) for 3 hours daily over an entire year to study effects on microRNAs - tiny molecules that control gene activity in the brain. The radiation significantly decreased levels of one specific microRNA (miR-107) that helps regulate brain cell function. This finding suggests that long-term cell phone use may disrupt the brain's genetic control systems, potentially leading to neurological problems.

Researchers exposed rats to cell phone-level radiation for 2 hours daily over 32 days. The radiation disrupted natural 24-hour cycles of antioxidant production, with nighttime exposures causing the biggest drops in protective compounds like melatonin. This suggests RF radiation may interfere with the body's internal clock.
