This in vitro study exposed BEAS-2B human bronchial epithelial cells to a 1.8-GHz continuous EMF at SAR 1.0 W/kg and assessed wound-healing related endpoints. EMF exposure decreased cell migration in a scratch assay compared with controls. The authors report no cytotoxicity, no inhibition of proliferation, and no…

This animal study exposed 12-week-old male Swiss strain mice to non-thermal low-level 2.45-GHz microwave radiation for 2 hours per day over 30 days (SAR 0.018 W/kg). The abstract reports reduced sperm count and viability, testicular structural changes, lower 3β-HSD activity and plasma testosterone, and increased…

This animal study examined oxidative stress and antioxidant defenses in loach embryos exposed to GSM 900 MHz microwave radiation (SAR 1.1 W/kg) for 1–20 minutes during early embryogenesis. The authors report significant changes in lipid peroxidation products and altered antioxidant enzyme activities. They conclude…

This animal study measured ROS in Drosophila bodies and ovaries after short- and long-term exposure to DECT base RF (1.88–1.90 GHz; SAR 0.009 W/kg). The abstract reports increased ROS in bodies after 6 h exposure and in ovaries after 0.5–1 h exposure, with apparent saturation under longer continuous exposure. It also…

This cross-sectional analysis used three Korean databases (2008–2011; n=21,693) to describe mobile phone ownership and use among children and adolescents and how these patterns vary by socioeconomic position. Ownership and use were higher among females, older students, and in 2011 compared with 2008, and the age of…

This rat study tested whether acute exposure to 0.9 and 1.8 GHz continuous-wave radiofrequency radiation alters blood-brain barrier permeability. Using Evans-blue/albumin as a tracer, the authors report no BBB leakage in exposed female rats but a significant increase in albumin in exposed male rat brains versus sham.…

This animal study assessed DNA damage in rat brain, liver, and kidney cells after repeated whole-body exposure to 915 MHz GSM-modulated RF radiation (SAR 0.6 W/kg) using the comet assay. Tail length was slightly increased in brain cells and differed more notably in liver and kidney samples versus sham controls, while…

This in vitro study examined whether a 50 Hz sinusoidal magnetic field affects the sarcoplasmic reticulum calcium release channel RyR1. A 0.4 mT exposure for 30 minutes increased SR Ca2+ release rate and [(3)H]-ryanodine binding under NADH/NAD+ conditions. The authors also report increased NADH oxidation and…

This review describes public concerns and scientific reports of non-thermal biological effects from low-intensity ELF and RF exposures. It lists multiple health endpoints reported to be associated with ELF and/or RF and highlights the BioInitiative Report’s conclusion that a reasonable suspicion of risk exists at…

This in vitro study exposed primary cultured rat neurons to 1.8 GHz RF-EMF at an average SAR of 2 W/kg and assessed gene expression changes. The authors report multiple differentially expressed genes after 24 h intermittent exposure and confirm exposure-dependent changes in Egr-1, Mbp, and Plp by semi-quantitative…
