This animal and in vitro study examined non-thermal 900 MHz RF-EMF exposure during prenatal and postnatal development at 0.08 and 0.4 W/kg SAR. The authors report changes consistent with altered neurodevelopment, including reduced BDNF, reduced in vivo cell proliferation, and disrupted synaptic balance in rat pup brain regions. In vitro, exposed neural stem cells showed increased apoptosis and DNA double-strand breaks and shifts in cell populations toward glial lineages. The authors conclude that regulatory-level 900 MHz exposure can disrupt key neurodevelopmental processes in rodents.

This study reports on 26 adults self-diagnosed with electromagnetic hypersensitivity (EHS) who provided skin biopsies to generate primary fibroblast lines. The authors describe two EHS subsets based on questionnaire and DNA damage-related measures, and report delayed ATM nucleoshuttling after X-ray exposure in all samples, interpreted as impaired DNA repair signaling. They propose a molecular model linking EHS to ATM pathway dysfunction and suggest this could relate to increased cancer risk or accelerated aging.
