This study examined the effects of long-term evolution (LTE) radiofrequency electromagnetic fields (1760 MHz at 4 W/kg SAR) on neuroblastoma cell proliferation in SH-SY5Y cells. The researchers found that RF-EMF exposure decreased cell growth and proliferation by inducing cellular senescence through the Akt/mTOR pathway, which activated p53 and its downstream CDK inhibitors, ultimately delaying the cell cycle without causing DNA damage or apoptosis.

Researchers exposed pregnant rats to 900-MHz electromagnetic fields (typical cell phone frequency) for one hour daily during late pregnancy and examined the offspring's spinal cords at one month old. The exposed pups showed significant structural damage, including degenerated motor neurons, enlarged central canals, and altered ependymal cells, along with reduced levels of H3K27me3, an epigenetic marker essential for neural stem cell maintenance. This study provides evidence that prenatal EMF exposure can cause lasting structural and molecular changes in the developing nervous system.

This study examined whether long-term evolution (LTE) radiofrequency electromagnetic field (EMF) exposure affects DNA damage in skin cells and mouse models. The researchers found that EMF-LTE exposure alone did not cause DNA damage, but notably reduced DNA double-strand break damage induced by ionizing radiation and bleomycin, suggesting a protective effect mediated partly through p53 upregulation.

Turkish researchers exposed fruit fly larvae to cell phone radiation at 900 MHz, 1800 MHz, and 2100 MHz frequencies for varying durations and found statistically significant increases in genetic mutations compared to unexposed controls. The study used fruit flies because their genes are remarkably similar to human disease genes. This research adds to evidence that radiofrequency radiation from mobile phones and base stations can cause DNA-level damage in living organisms.

Scientists exposed mouse bone marrow stem cells to 900 MHz radiofrequency radiation (cell phone frequency) for 4 hours daily over 5 days. The radiation triggered cellular stress responses and increased harmful molecules called reactive oxygen species, though cells appeared to recover within 24 hours. This shows that even brief daily cell phone radiation exposure can disrupt normal cellular function at the mitochondrial level.

Researchers exposed rats to 10 GHz microwave radiation for 3 hours daily over 30 days at power levels twice the occupational safety limit. The study found significant skin temperature increases, oxidative stress, inflammation, and cellular stress responses in exposed animals, though no cell death occurred. The findings suggest that chronic microwave exposure at levels currently deemed 'safe' for workers can trigger biological stress responses in skin tissue.

Researchers exposed rats to 4.5G mobile phone radiation for 2 hours daily over 6 weeks and found significant damage to the optic nerve, which carries visual information to the brain. The radiation reduced nerve signal strength, thinned protective myelin coating, and increased harmful oxidative stress markers. This suggests that newer, faster mobile networks may pose previously unrecognized risks to vision and eye health.

Researchers exposed rats to 900 MHz cell phone radiation for one hour daily over 28 days and found significant damage to brain cells in the hippocampus, the brain region crucial for memory and learning. The study also tested whether natural compounds like curcumin and Garcinia kola could protect against this damage, finding that both substances provided significant protection. This adds to growing evidence that cell phone radiation can harm brain tissue at the cellular level.

Estimated whole-brain and lobe-specific radiofrequency electromagnetic fields doses and brain volumes in preadolescents Alba Cabré-Riera et al. · 2020
Dutch researchers studied 2,592 children aged 9-12 to see if radiofrequency radiation from phones, tablets, and WiFi affected their brain structure using MRI scans. They found no association between RF exposure and overall brain volumes, but children with higher exposure from internet-connected devices had slightly smaller caudate brain regions. The researchers noted this finding might reflect lifestyle factors rather than radiation effects.

Researchers analyzed existing scientific literature on wireless radiation health effects, focusing on how 5G technology may impact human health under real-world conditions. The study found that most laboratory experiments fail to replicate actual exposure conditions, missing important factors like signal pulsing and interactions with other environmental toxins. The authors conclude that 5G will likely cause systemic health effects beyond just skin and eye damage.
