Rouleaux in Real Time: Ultrasound Evidence, Red Blood Cells, and the S4–Mito–Spin Mechanism
RF Safe argues that red blood cell (RBC) “rouleaux” (stacking/aggregation) could be a visible, testable endpoint for investigating potential short-term physiological effects from wireless device exposure. The post highlights a 2025 report by Brown & Biebrich describing ultrasound observations interpreted as rouleaux-like aggregation after 5 minutes of smartphone placement near the popliteal vein, and contrasts this with earlier, more-criticized “live blood analysis” videos. It frames rouleaux as an electrostatic/zeta-potential phenomenon and calls for mechanistic testing and exposure mitigation, while presenting the ultrasound observation as a key shift toward more clinically standard imaging.
Looking for Biomarkers Which May Explain Idiopathic Environmental Intolerance Attributed to EMF (IEI-EMF): Does RF-EMF Exposure Influence Salivary Cortisol Response?
This randomized, double-blind, counterbalanced provocation study tested whether short-term RF-EMF exposure alters salivary cortisol in 72 predominantly young, healthy adults. Active exposure (2 W/kg peak SAR10g in head) showed no significant effect on cortisol compared with sham, and no sex differences were observed. The authors note that results may not rule out effects in populations not studied and encourage further research into plausible biological interactions.
Pilot questionnaire survey shows the lack of diagnostic criteria for electromagnetic hypersensitivity: a viewpoint
This viewpoint reports results from a pilot questionnaire survey of 142 self-declared EHS/IEI-EMF individuals and argues that current evidence and tools do not allow a definitive medical diagnosis of sensitivity to low-level wireless radiation. It notes that many reported diagnoses appear anecdotal and that tests used lack scientific proof for detecting such sensitivity. The article also considers individual sensitivity plausible and calls for controlled provocation and biochemical studies to develop diagnostic biomarkers.
Skin Fibroblasts from Individuals Self-Diagnosed as Electrosensitive Reveal Two Distinct Subsets with Delayed Nucleoshuttling of the ATM Protein in Common
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.
