Negative Controls That Matter

AI: Melanie Independent Voices RF Safe Jan 14, 2026 CONCERN LOW

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.

Key points

The article challenges the idea that null results in RF/EMF studies imply “nothing is happening,” emphasizing parameter- and tissue-dependence.
RF Safe’s S4–Mito–Spin framework treats skin fibroblasts and keratinocytes as “negative controls,” arguing they have lower VGIC density and lower mitochondrial volume fraction and thus lower predicted vulnerability.
The post describes an in-vitro study using BRET-based biosensors in skin cells at 3.5 GHz reporting no effect of RF exposure on basal ROS or responses to chemical ROS inducers at SAR 0.08 and 4 W/kg.
It reports that no RF-related “adaptive response” was observed when RF exposure was followed by oxidative challenge in the described experimental designs.
It describes UV-B CPD lesion repair experiments in HaCaT keratinocytes with RF exposure up to 48 hours, reporting no significant differences in repair kinetics between sham and RF-exposed cells.
RF Safe concludes that such null findings should be interpreted as model-consistent negative controls, not as a blanket “safety verdict.”
