Researchers tracked radiofrequency electromagnetic field (RF-EMF) exposure from phones, tablets, and other devices in nearly 1,900 children aged 9-12 years, measuring their sleep patterns with wrist monitors for a week. Children with high evening phone call exposure slept about 12 minutes less per night compared to those with no evening phone exposure. The study couldn't determine whether the sleep disruption came from the RF-EMF radiation itself or from the stimulating activities that prompted the phone calls.

This large-scale genetic study analyzed over 219,000 COVID-19 cases and 3 million controls to identify genetic factors affecting virus susceptibility and severity. Researchers found 51 genetic locations linked to COVID-19 outcomes, mapping three key biological pathways: viral entry mechanisms, airway mucus defense, and immune interferon responses. The findings help explain why some people experience more severe COVID-19 symptoms than others.

Iraqi researchers studied 43 people living near internet towers for 1-10 years, measuring oxidative stress markers in their blood compared to 20 unexposed controls. They found significant increases in cellular damage markers and disrupted antioxidant systems in those exposed to tower radiation. This suggests chronic exposure to internet infrastructure may harm the body's ability to fight cellular damage.

Spanish researchers surveyed 268 residents living near nine cell phone towers in Madrid and measured electromagnetic radiation levels in their homes. People exposed to higher radiation levels experienced significantly more headaches, nightmares, dizziness, and sleep problems. The neighborhood also showed cancer rates 10 times higher than the Spanish national average.

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.

Researchers studied how young adults perform reaching tasks while sitting versus standing, comparing when eye and hand movements go the same direction versus opposite directions. They found that when standing and performing the more challenging opposite-direction task, people automatically reduced their body sway to maintain better control. This reveals how our brain prioritizes complex motor tasks by stabilizing our posture.

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.

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.
