This French GEOCAP registry-based case-control study evaluated childhood acute leukemia risk in relation to residential proximity to high-voltage overhead power lines and modeled ELF magnetic-field exposure. It reports an increased risk for children under 5 living within 50 m of power lines, particularly when restricting to high-quality geocoded addresses. However, modeled ELF-MF exposure >0.3 µT was not associated with increased risk, and the authors suggest proximity may capture other factors and call for further research and precaution.
Use of Electrical Household Appliances and Risk of All Types of Tumours: A Case-Control Study
This multi-hospital case-control study (n=316) examined associations between use of common household electrical appliances emitting ELF EMF and tumour risk. Most devices showed below-unity odds ratios, while computer screen and microwave oven use showed slightly increased odds with wide confidence intervals. Proximity to electricity transformer stations was associated with higher tumour odds, whereas proximity to powerlines was not.
Magnetoreception and the ruling hypothesis
This article is a commentary on how emotions and community dynamics can bias scientific reasoning when a favored hypothesis becomes a "ruling hypothesis." Using animal magnetoreception as an example, it argues that radical-pair/cryptochrome-centered frameworks may sometimes be treated as dominant, potentially leading to selective interpretation of evidence. The authors call for separating individual intent from community-wide bias and offer recommendations to mitigate these risks.
Effect of electromagnetic field radiation on transcriptomic profile and DNA methylation level in pig conceptuses during the peri-implantation period
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.
Potential influence of geomagnetic activity on blood pressure statistical fluctuations at mid-magnetic latitudes
This six-year time series analysis used over 500,000 blood pressure measurements from two mid-magnetic latitude cities in China to examine associations with geomagnetic activity (Ap index). The study reports that blood pressure fluctuations correlate with geomagnetic activity and share similar periodic patterns, unlike air temperature and PM2.5. The authors conclude that high geomagnetic activity periods may increase risk for individuals with hypertension and note potential clinical and policy relevance.
Earth's magnetic field and its relationship to the origin of life, evolution and planetary habitability
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)
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.
Use of Mobile and Cordless Phones and the Association with Prostate Cancer
This pooled analysis of two prior human studies reports increased odds of prostate cancer associated with mobile phone use, with higher estimates for longer latency and higher cumulative hours. Cordless phone use is reported to show increased risk but not statistically significant overall, with one mid-range cumulative use category showing an elevated OR. The abstract also reports higher risks among men with more aggressive prostate cancer and among those with a family history of prostate cancer.
Could electrohypersensitivity be a specific form of high sensory processing sensitivity?
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.
Self-diagnosing electromagnetic hypersensitivity-A case study
No abstract was provided in the source text. The provided overview indicates this is a case study of self-diagnosed electromagnetic hypersensitivity (EHS), describing symptoms attributed by an individual to EMF exposure. The supplied text emphasizes ongoing concern about potential health risks and calls for rigorous scientific inquiry and support for affected individuals.
RF-EMF exposure assessment with add-on uplink exposure sensor in different microenvironments in seven European countries
This exposure assessment study introduces a cost-efficient add-on sensor attached to a smartphone to quantify auto-induced uplink RF-EMF transmission across 100–6000 MHz in multiple microenvironments. Activity-based surveys were conducted in seven European countries under non-user, maximum downlink, and maximum uplink scenarios. Reported power levels were lowest for non-user scenarios and higher during active use, with variation by country, urbanization, and setting. The authors frame the work as supporting future epidemiological research and planned validation against other tools.
The Effect of Proximity Sensor & Grip Sensor Use on Specific Absorption Rate (SAR) in Smartphones
This engineering study examined how smartphone proximity and grip sensors affect SAR during LTE and 5G NR operation in a 3D measurement environment. The abstract reports that enabling these sensors reduces SAR relative to being turned off, with reductions varying by sensor and frequency. The authors attribute the reduction to sensor-driven power management and transmission power adjustment.
Repeated Head Exposures to a 5G-3.5 GHz Signal Do Not Alter Behavior but Modify Intracortical Gene Expression in Adult Male Mice
This animal study examined repeated asymmetrical head exposure to a 5G-modulated 3.5 GHz signal in adult male mice for six weeks. It reports no significant changes in locomotion, anxiety, or object-based memory performance under the tested conditions. However, it found statistically significant but limited cortical gene expression changes (<1% of expressed genes), including enrichment for glutamatergic synapse-related genes and lateralized differences involving mitochondrial genome-encoded genes. The authors caution that potential health risks from these intracortical transcriptomic modifications should not be downplayed and note uncertainties about longer exposures and other populations.
5G Radiofrequency Exposure Reduces PRDM16 and C/EBP � mRNA Expression, Two Key Biomarkers for Brown Adipogenesis
This animal study exposed juvenile and young adult Wistar rats to 5G (3.5 GHz) or 2G (900 MHz) radiofrequency fields (1.5 V/m) for 1–2 weeks and measured brown adipose tissue-related gene expression by RT-qPCR. The abstract reports significant downregulation of PRDM16 and C/EBP mRNA after 5G exposure, while UCP1-dependent thermogenesis markers were not significantly changed at the transcriptional level. The authors interpret these findings as a potential partial disruption of brown adipocyte differentiation and raise EMF safety concerns, while calling for further confirmatory research.
The CB1R of mPFC is involved in anxiety-like behavior induced by 0.8/2.65 GHz dual-frequency electromagnetic radiation
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.
Histomorphometry and Sperm Quality in Male Rats Exposed to 2.45 GHz Wi-Fi
This animal study exposed adult male rats to 2.45 GHz Wi‑Fi from an active router for 4 or 24 hours daily over eight weeks and assessed reproductive organ histology and sperm parameters. The authors report histological changes in testes and epididymis, multifocal atypical hyperplasia in seminal vesicles, reduced seminiferous tubule diameter, and reduced spermatogenesis index in exposed groups. Sperm concentration decreased in both exposed groups, motility decreased in the 4-hour group, and viability increased in the 24-hour group, leading to an overall interpretation of potential reproductive risk under the studied conditions.
The Frequency of a Magnetic Field Determines the Behavior of Tumor and Non-Tumor Nerve Cell Models
This in vitro study exposed glioblastoma (CT2A), neuroblastoma (N2A), and non-tumor astrocyte (C8D1A) cell models to a 100 μT magnetic field across 20–100 Hz for 24–72 hours. The abstract reports decreased viability and proliferation in the tumor cell models within a frequency window centered at 50 Hz, while astrocyte viability increased at 20 and 40 Hz. The authors conclude that frequency is a key determinant of cell-type-specific responses consistent with a “biological window” model.
Extremely low frequency magnetic field distracts zebrafish from a visual cognitive task
This animal study trained adult zebrafish to perform a conditioned avoidance response to a visual cue. The visual cue was presented alone or together with an extremely low frequency sinusoidally changing magnetic field (0.3 Hz) at 0.015 mT or 0.06 mT. The abstract reports that the 0.06 mT magnetic field condition impaired learning performance and response behavior, suggesting a cross-modal distraction effect.
Effects of moderate static magnetic fields on voltage-gated potassium ion channels in sympathetic neuron-like PC12 cells
This in vitro study examined effects of moderate static magnetic field exposure on sympathetic neuron-like PC12 cells. The authors report a significant reduction in voltage-gated potassium (Kv) channel current density after 18 hours of exposure, with the reduction persisting after the field was removed. RNA sequencing identified 37 SMF-sensitive genes and pathway analyses suggested upregulation of signaling associated with reduced neuronal excitability.
Enhancement Effect of Static Magnetic Field on Bactericidal Activity
This in vitro study reports that a static magnetic field (SMF) combined with paramagnetic calcium-polypyrrole nanoparticles (Ca-PPy) markedly increases bactericidal activity against E. coli and S. aureus. The authors attribute the enhanced killing to increased reactive oxygen species generation and associated membrane disruption, with computational analysis suggesting altered radical-pair transitions under magnetic fields. The abstract frames SMF as potentially biocompatible and useful for bactericidal applications, while also noting broader biological impacts of electromagnetic fields.
