This in vitro study exposed pig conceptuses (days 15–16 of pregnancy) to 50 Hz ELF-EMF for 2 hours and assessed transcriptomic and DNA methylation changes. The authors report altered expression of 21 protein-coding transcripts and an approximately 16-fold increase in genomic DNA methylation, with promoter methylation changes in several named genes. They conclude ELF-EMF interacts with gene expression and DNA methylation processes during early development and call for further safety research.

Earth's magnetic field and its relationship to the origin of life, evolution and planetary habitability

Research RF Safe Research Library Jan 1, 2025

This review synthesizes evidence on Earth's geomagnetic field history and discusses how early establishment of the field (at least 4.2 billion years ago, inferred from zircon magnetism) may have supported planetary habitability via radiation shielding and water preservation. It highlights a proposed near-collapse of the dynamo near the end of the Precambrian and subsequent renewal in the earliest Cambrian, with potential implications for atmospheric escape and oxygenation. The paper frames several links to biological evolution (including Ediacara fauna) as possible and in some cases debated.

The effects of radiofrequency radiation on male reproductive health and potential mechanisms (Review)

Research RF Safe Research Library Jan 1, 2025

This narrative review summarizes human and animal research on radiofrequency (RF) radiation exposure (e.g., mobile phones, Wi‑Fi, occupational sources) and male reproductive outcomes. It reports that the literature links RF exposure with reduced sperm quality and increased DNA damage, often alongside oxidative stress and other proposed biological changes. Although inconsistencies are acknowledged, the authors conclude the overall evidence suggests harmful associations and call for standardized, long-term studies and reconsideration of guidelines.

Could electrohypersensitivity be a specific form of high sensory processing sensitivity?

Research RF Safe Research Library Jan 1, 2025

This cross-sectional questionnaire study (n=100) examined whether electrohypersensitivity (EHS) overlaps with high sensory processing sensitivity (HSPS). A higher proportion of HSPS was observed among those reporting EHS symptoms, alongside significant differences in anxiety/depression symptomatology and EMF-related risk perception and avoidance strategies. The authors interpret the results as supporting an association between EHS and HSPS, while noting that this does not establish whether EM radiation directly causes EHS symptoms.

The CB1R of mPFC is involved in anxiety-like behavior induced by 0.8/2.65 GHz dual-frequency electromagnetic radiation

Research RF Safe Research Library Jan 1, 2025

This animal study reports that dual-frequency RF EMR exposure (0.8/2.65 GHz, 4 W/kg) induced anxiety-like behavior in mice. It also reports reduced CB1R and endocannabinoid levels in the mPFC and altered endocannabinoid system markers in the BLA. CB1R overexpression or knockdown in the mPFC reportedly decreased or increased anxiety-like behavior, respectively, suggesting a mechanistic link in this model.

Research RF Safe Research Library Jan 1, 2024

This conference abstract reports a pilot matched case-control study examining whether carrying a cellphone below the waist is associated with early-onset colorectal cancer (EOCRC). The authors report higher EOCRC likelihood among those who carried phones below the waist, with the strongest association for ipsilateral carrying (same side as the tumor) and high cumulative hours. Details on exposure measurement, confounding control, and full statistical reporting are not provided in the abstract.

The use of different exposure metrics in the research about the health impacts of electromagnetic fields

Research RF Safe Research Library Jan 1, 2024

This policy brief focuses on how RF-EMF exposure should be quantified in health research, emphasizing the role of near-field sources and proposing cumulative dose (J/kg/day) as a health-relevant metric. It reports mean cumulative dose estimates of 0.29 J/kg/day for the whole body and 0.81 J/kg/day for the brain. The brief notes established RF-EMF effects (heating, microwave hearing under highly pulsed radiation, and stimulation) and discusses indications of biological effects below thermal thresholds, while stating that improved metrics do not by themselves confirm harm.
