Negative Controls That Matter

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…
Why the 2025 “5G Skin-Cell Null” Actually Confirms the Density-Dependence of Both Pillars of the Unified Framework

RF Safe comments on a 2025 PNAS Nexus study (Jyoti et al., 2025) reporting no detectable changes in gene expression or methylation in 5G millimeter-wave–exposed human skin cells. The post argues that this “null” result does not indicate biological inertness, but instead supports the site’s proposed “dual-pillar”…
Impact of in vitro exposure to 5G-modulated 3.5 GHz fields on oxidative stress and DNA repair in skin cells

This in vitro study tested whether 5G-modulated 3.5 GHz RF-EMF exposure affects oxidative stress and DNA repair in human skin cells. Under acute exposure conditions (up to 24–48h) at SARs up to 4 W/kg, the authors report no significant changes in ROS markers, no adaptive response to oxidative challenge, and no…
