RF Safe
Dec 16, 2025
An RF Safe commentary argues that persistent, pulsed “non-native” RF electromagnetic noise can disrupt biological “timing coherence,” leading to downstream “fidelity losses,” particularly in electrically active tissues. It also emphasizes that smartphones are adaptive RF systems that change transmit power and…
How non‑native electromagnetic fields, biological timing, and policy lock in converge — and why the Light Age is the only coherent exit

RF Safe
Dec 13, 2025
RF Safe argues that modern radiofrequency (RF) exposures are complex (adaptive, nonlinear, geometry- and near-field–dependent) and that biological effects, if any, may be better understood as “timing/coherence” disruptions rather than direct single-cause disease claims. The piece cautions against simplistic “percent…
