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”…

This in vitro study exposed human skin cells (fibroblasts and keratinocytes) to 5G-band electromagnetic fields for 2 hours and 48 hours using a fully blinded design. Exposures were up to ten times permissible limits, with sham exposure as a negative control and UV exposure as a positive control. The study reports…

This in vitro study tested whether daily exposure to a 10 mT ELF electromagnetic field, combined with miR-16 and miR-451 transfection, could enhance trans-differentiation of human dermal fibroblasts toward erythroid-like progenitors. The authors report increased erythroid-like differentiation with ELF-EMF exposure,…

This narrative review discusses reported effects of EMF, including low-frequency EMF (LF-EMF), on cell behaviors relevant to wound healing and on recovery processes after traumatic brain injury (TBI). It summarizes literature suggesting EMF can promote migration and proliferation of fibroblasts, keratinocytes, and…

This randomized animal study evaluated whether recombinant murine EGF combined with ELF-EMF improves wound healing in rats. The combined ELF-EMF+rmEGF group showed better wound healing rates and more favorable histological features than comparison groups at multiple time points. All groups had complete wound closure…

This in vitro study examined NIH/3T3 fibroblast cells exposed to 2100 MHz EMF and evaluated cell viability, cyclin D1, and NF-κB activity, with and without 200 nM selenium. The abstract reports reduced cell viability and increased cyclin D1 and NF-κB activity after EMF exposure. Selenium supplementation was reported…
