Researchers exposed healthy sperm samples to active cell phone radiation for 60 minutes at close range (2.5 cm) and compared them to control samples exposed to inactive phones. The cell phone radiation significantly reduced sperm viability and movement while increasing DNA damage and cell death. This laboratory study demonstrates that radiofrequency radiation from phones can harm sperm quality even in short exposures.

Researchers in Iraq measured antioxidant levels in 43 people living near internet towers (exposed for 1-10 years) compared to 20 unexposed controls. Those exposed showed significantly increased oxidative stress markers (MDA and peroxynitrite) and altered antioxidant enzyme levels, indicating cellular damage from chronic radiofrequency exposure. This suggests living near wireless infrastructure may compromise the body's natural defenses against free radical damage.

Researchers examined 15 studies linking workplace exposure to extremely low-frequency magnetic fields (like those from power lines and electrical equipment) with amyotrophic lateral sclerosis (ALS), a fatal neurological disease. The analysis found these studies were too different in methods to draw firm conclusions, but showed enough promise to justify a major pooled study. Eight research teams agreed to share their original data for better analysis.

Researchers used EEG brain wave measurements to study how mobile phone electromagnetic radiation affects brain activity in real-time. They compared brain wave patterns when participants were not using phones versus when actively using them. The study found measurable changes in brain electrical activity during mobile phone use, suggesting the radiofrequency energy does influence neural function.

This study examined how methodological factors influence the detection of radiofrequency electromagnetic field (RF-EMF) effects on EEG alpha power in 36 adults exposed to sham, low, and high RF-EMF conditions. The researchers found that alpha power increases were greater during eyes-open versus eyes-closed EEG recordings and showed a trend toward larger increases later in the exposure period, suggesting that previous studies using eyes-closed conditions or shorter exposure durations may have failed to detect RF-EMF effects.

European researchers studied over 3,200 children and teens to measure radiofrequency radiation doses to their brains from phones, tablets, and other wireless devices. They found that higher brain radiation exposure was linked to lower non-verbal intelligence scores in 9-11 year olds. The effect was small but consistent across multiple countries.

Researchers exposed 30 young men to Wi-Fi radiation (2.45 GHz) all night while they slept to test effects on memory formation. Surprisingly, participants performed slightly better on word memory tasks after Wi-Fi exposure, though brain activity measurements showed no changes. The authors suggest this unexpected finding may be random rather than meaningful.

Researchers exposed blood cells from 5 men to 900 MHz cell phone frequency radiation for up to 90 minutes, analyzing changes in 667 microRNAs that regulate gene expression. While they initially found 2 microRNAs that appeared to respond to EMF exposure, these changes could not be reproduced when the experiment was repeated 2 years later. The study found no consistent evidence that brief 900 MHz exposure alters microRNA expression in human blood cells.

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.

Researchers measured brain wave activity using EEG tests to determine if mobile phone electromagnetic radiation affects brain function. They compared brain activity when participants were not using phones versus when actively using them. This study examined whether the radiofrequency energy absorbed by your head during phone calls creates measurable changes in neural activity.
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.

This study examined immune responses in the mollusk Onchidium struma exposed to 50 Hz extremely low-frequency electromagnetic fields (ELF-EMF) at two intensity levels (100 μT and 500 μT) by measuring immune enzyme activities and analyzing gene expression through transcriptome sequencing. The exposure increased immune-related enzyme activities and identified 341 differentially expressed genes, with five immune-related signaling pathways affected, suggesting that short-term ELF-EMF exposure at lower field densities can trigger immune responses in this aquatic organism.

Researchers tested whether pulsed electromagnetic fields (PEMF) could help grow new cartilage by stimulating cells from human knee joints. They found that PEMF exposure didn't significantly improve cartilage formation compared to standard chemical treatments. The study suggests PEMF may work through different biological pathways than previously thought.

Researchers exposed human immune cells to a 6 milliTesla static magnetic field and found it altered the cell membrane structure in ways that significantly increased uptake of silver nanoparticles. The magnetic field caused changes in lipid rafts (specialized areas of the cell membrane), increased oxidative stress, and made cells more permeable to nanoparticles. This suggests that common environmental magnetic field exposures could be changing how substances enter our cells.
