RF Safe argues that “no effect” findings in some RF exposure studies should be interpreted as meaningful negative controls rather than as evidence that RF has no biological effects. The post presents RF Safe’s “S4–Mito–Spin” framework, claiming certain skin cell types (fibroblasts and keratinocytes) are predicted to be relatively resistant to non-thermal RF effects, so null results in these cells can be consistent with the model. It cites in-vitro studies at 3.5 GHz (5G-modulated) reporting no changes in ROS measures, stress responses, or UV-B DNA repair kinetics under specified SAR conditions, and frames these nulls as boundary conditions rather than a general safety conclusion.

This RF Safe article argues that everyday electromagnetic fields (EMFs) could act as a weak “magnetic co‑zeitgeber,” subtly influencing circadian timing alongside light. It proposes a mechanism in which EMFs modulate cryptochrome radical‑pair spin dynamics, potentially nudging circadian phase and downstream processes such as melatonin rhythms, immune function, epigenetic programming, and DNA repair. The piece presents the idea as a framework with testable implications while acknowledging uncertainties, but it is primarily explanatory/commentary rather than reporting new study results.

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.
