This animal study exposed adult male rats to 2.45 GHz electromagnetic radiation for 2 hours/day for one month and assessed testicular outcomes. The abstract reports that EMR exposure induced oxidative stress, increased inflammatory markers, and caused histological testicular injury. Alpha-lipoic acid supplementation was reported to mitigate these changes and restore several testicular proteins.
Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito
This animal study exposed Aedes aegypti larvae to 5G-NR RF-EMF at 3.6 GHz for 5 days under two feeding regimes. The study reports delayed development at a lower exposure level mainly in nutritionally weakened larvae, and at a higher exposure level reports developmental changes and reduced adult size attributed to dielectric heating. Mortality and wing length asymmetry were reported as unchanged, and the authors note such high exposure levels are unlikely in natural aquatic settings.
Development and Testing of a Novel Whole-body Exposure System for Investigative Studies of Radiofrequency Radiation in Rodents (NIEHS)
This NIEHS report describes the development and testing of a flexible whole-body radiofrequency radiation exposure system for rats and mice using updated signals relevant to wireless technologies. In 5-day studies with CDMA- and GSM-modulated signals, no visible behavioral responses were observed and comet assays reported no DNA damage in multiple tissues. The report notes technical challenges, particularly difficulty obtaining reliable body temperature measurements during exposure, and positions the system as a prototype for future mechanistic toxicology studies.
The effects of electrical stimulation on neurons and glia of the central nervous system
This review synthesizes evidence on how direct current and alternating current electrical stimulation affect neurons and glia in the central nervous system, spanning basic research and clinical translation. It reports polarity- and parameter-dependent effects on axonal growth, along with immunomodulatory glial responses that may favor regeneration and enhanced myelination via OPC differentiation. The authors note early clinical applications with potential longer-term functional improvements, while emphasizing that stimulation parameters and patient context can influence risks and benefits.
Causal relationship between duration of mobile phone use and risk of aneurysmal subarachnoid hemorrhage: A 2-sample Mendelian randomization analysis
This two-sample Mendelian randomization study examined whether duration of mobile phone use is causally related to aneurysmal subarachnoid hemorrhage using large European GWAS datasets. The primary MR analysis reported that excessive duration of mobile phone use was associated with higher aSAH risk, and sensitivity analyses were described as supportive. The authors conclude the findings have potential clinical, public health, and policy implications.
Personal radio use and risk of cancers among police officers in Great Britain: Results from the airwave health monitoring study
This prospective cohort analysis from the Airwave Health Monitoring Study evaluated whether occupational personal radio (TETRA) use is associated with cancer risk among 48,457 police officers and staff. Over a median 11 years of follow-up, the study reports no association with all cancers or with head/neck/CNS cancers, and no evidence of a non-linear dose-response with call duration. The authors emphasize that confidence intervals were wide and that a modestly increased risk at high usage cannot be ruled out, supporting continued monitoring.
Radiofrequency radiation from mobile phones and the risk of breast cancer: A multicenter case-control study with an additional suspected comparison group
This multicenter case-control study in Iran (n=226) examined associations between mobile phone use and breast cancer outcomes in women. Reporting more than 60 minutes/day of phone conversations was associated with higher odds of confirmed invasive breast cancer and of being classified as a suspected case versus <10 minutes/day. The authors emphasize that the results do not establish causation and may be influenced by self-reported exposure and residual confounding, warranting cautious interpretation.
No Measurable Impact of Acute 26 GHz 5G Exposure on Salivary Stress Markers in Healthy Adults
This triple-blind randomized study tested whether 26.5 minutes of 26 GHz (5G) RF exposure at environmental-like levels alters salivary stress biomarkers in healthy adults. Salivary cortisol and alpha-amylase measured before, during, and after exposure did not differ between real and sham conditions. An exploratory subgroup with frequent sampling also showed biomarker stability over time. The study addresses acute exposure only and notes the need for research on repeated or long-term exposures and vulnerable groups.
Definition and Validation of an Exposure Measurement Method for a Typical Load of a Base Station
This exposure-assessment study proposes and validates a method to measure instantaneous RF exposure under typical base station load by generating defined data rates (low/medium/high) using iPerf and measuring channel power across services. Validation at four base stations suggests the approach is reliable across different times of day and loads, with reproducible results when averaging over 30 sweeps. Comparisons indicate iPerf-provoked constant data rates generally match exposure during real application usage, with few deviations beyond stated uncertainty.
Millimeter-wave high frequency 5G (26 GHz) electromagnetic fields do not modulate human brain electrical activity
This randomized, triple-blind crossover study examined whether 26 GHz (5G millimeter-wave) exposure affects human EEG activity. Thirty-one healthy young adults completed real and sham 26.5-minute exposures at 2 V/m, with EEG recorded before, during, and after exposure. The study reports no significant effects of exposure on delta, theta, alpha, or beta band power across electrode clusters, providing preliminary reassurance under the tested conditions.
Behaviour and reproduction of Drosophila melanogaster exposed to 3.6 GHz radio-frequency electromagnetic fields
This animal study assessed whether 3.6 GHz RF-EMF exposure affects behaviour and reproduction in adult Drosophila melanogaster, using micro-CT-based digital-twin dosimetry and numerical simulations. It reports no significant changes in locomotor activity after 5 days at 5.4–9 V/m and no effect on fecundity over 48 hours at the tested absorbed power. The authors note that effects could still be possible at other exposure levels or in different developmental stages.
Time-Dependence Effect of 2.45 GHz RF-EMR Exposure on Male Reproductive Hormones and LHCGR
This animal study exposed male Sprague Dawley rats to 2.45 GHz Wi-Fi for varying daily durations over eight weeks and assessed reproductive hormones and LHCGR expression. Serum LH and testosterone did not differ significantly from controls, but LHCGR mRNA increased with longer exposure and LHCGR protein showed decreases with shorter exposures with partial improvement at 24 hours/day. The findings suggest molecular alterations in testicular tissue despite stable systemic hormone levels.
From adults to offspring: Wi-Fi RF-EMR exposure in adult zebrafish impairs reproduction and transgenerationally effects development and behavior of progeny
This animal study examined Wi-Fi RF-EMR exposure in adult zebrafish (4 hours/day for 30 days) and assessed reproductive tissues and offspring outcomes. The abstract reports testicular and ovarian histopathological abnormalities in exposed adults. Offspring from exposed parents, maintained under EMF-free conditions, reportedly showed increased mortality, morphological abnormalities, and anxiety-like behavior, with malformations increasing with longer parental exposure.
Electrical oscillations in microtubules
This study introduces a multi-scale electrokinetic model to characterize electrical impulses and ionic current propagation along microtubules, incorporating atomistic protein details and biological environments. It emphasizes nanopore-mediated coupling between microtubule surfaces as a key mechanism enabling luminal currents, energy transfer, amplification, and oscillatory dynamics. The authors report pharmacological inhibition experiments (Taxol and Gd3+) supporting the interpretation that nanopores function as active nanogates contributing to transistor-like behavior.
Role of visual and non-visual opsins in blue light-induced neurodegeneration in Drosophila melanogaster
This animal study used Drosophila knockout lines to examine whether visual (Rh1) versus non-visual (Rh7) opsins contribute to blue-light-associated neural damage. Flies were continuously exposed to 488 nm blue light from egg deposition to 20 days, and brain DNA damage and vacuolisation were assessed. The study reports greater DNA damage and neurodegeneration markers in Rh1 knockout flies than in wild-type or Rh7 knockout flies, and concludes Rh1 is a predominant mediator of blue-light-induced neurotoxicity in the fly CNS.
Non-thermal biological effects of radiofrequency electromagnetic radiation: Mechanistic insights into male reproductive vulnerability in the era of ubiquitous exposure
This narrative review discusses proposed non-thermal mechanisms by which chronic, low-intensity RF-EMR from ubiquitous wireless sources may affect male reproductive health. It highlights oxidative stress, mitochondrial dysfunction, impaired testosterone synthesis/steroidogenesis, and declines in sperm quality as reported outcomes. The authors argue that current SAR/thermal-based guidelines may not capture these endpoints and call for updated standards and precautionary measures.
Radiofrequency radiation-induced gene expression
This review summarizes studies reporting radiofrequency radiation (RFR)-associated changes in gene expression across biological systems. Reported affected genes relate to cellular stress responses, oxidative processes, apoptosis, DNA damage detection/repair, protein repair, and neural function regulation. The authors highlight reported gene expression effects at or below 0.4 W/kg SAR and argue this challenges current guideline assumptions, while noting that not all studies find significant effects.
Electromagnetic fields and oxidative stress: The link to the development of cancer, neurological diseases, and behavioral disorders
This review discusses epidemiological and mechanistic reports linking EMF exposure with oxidative stress and disease risk, and introduces an Electromagnetic Pathogenesis (EMP) conceptual model. The model proposes that non-ionizing EMFs increase mitochondrial electron leakage via electron tunneling, raising free radical production and oxidative stress. The authors argue oxidative stress is a primary mechanism connecting EMF exposure to cancer, cardiovascular, neurodevelopmental/neurodegenerative diseases, and behavioral/reproductive effects, and suggest reducing exposure may lower risk.
Transition Pathways Towards Electromagnetic Sustainability in the Built and Lived Environment
This paper discusses electromagnetic (EM) fields as an environmental health and sustainability issue in the built and lived environment, particularly with expanding ICT and energy systems. It reports conducting a literature review and EM field audits in three locations across two cities in Canada and the UK to examine exposure trends and review major safety guidelines. The authors propose transition pathways toward “electromagnetic sustainability,” emphasizing planning, exposure reduction, and risk governance.
The Influence of Mobile Technologies on the Quality of Sleep
This study assessed whether sleeping with versus without a mobile phone (two-week intervals) affects sleep in medical students, using smartwatch-based monitoring. It reports no statistically significant differences in sleep quality or time spent in wakefulness, REM, light, or deep sleep between conditions. The authors report a statistically significant effect on minimum and average blood oxygen saturation during sleep and call for further research on nightly RF-EMF exposure.
Effects of Simultaneous In-Vitro Exposure to 5G-Modulated 3.5 GHz and GSM-Modulated 1.8 GHz Radio-Frequency Electromagnetic Fields on Neuronal Network Electrical Activity and Cellular Stress in Skin Fibroblast Cells
This in-vitro study exposed primary cortical neurons and human immortalized skin fibroblasts to simultaneous 5G-modulated 3.5 GHz and GSM-modulated 1.8 GHz RF-EMF at SARs of 1 or 4 W/kg. It reports no significant changes in neuronal network firing/bursting activity and no alteration of mitochondrial ROS in fibroblasts. Stress-related signaling readouts showed only minor, threshold-level variations without a consistent pattern, and no HSF1 activation was observed. Overall, the authors conclude there is no strong evidence of biological effects under these exposure conditions.
Male Reproductive and Cellular Damage After Prenatal 3.5 GHz Radiation Exposure: One-Year Postnatal Effects
This animal study examined whether prenatal exposure to 3.5 GHz radiofrequency radiation (2 hours/day) affects male reproductive outcomes later in life. Male rat offspring assessed at 12 months showed multiple adverse testicular and cellular findings in exposed groups versus sham controls, including impaired spermatogenesis markers, increased abnormal sperm morphology, increased DNA damage, and increased apoptosis, with full-gestation exposure generally most pronounced. The authors interpret the results as evidence of persistent reproductive toxicity from prenatal exposure and call for further mechanistic work and precautionary actions.
Synergistic Effects of 2600 MHz Radiofrequency Exposure and Indomethacin on Oxidative Stress and Gastric Mucosal Injury in Rats
This rat study tested whether 2600 MHz radiofrequency field exposure interacts with indomethacin to affect gastric tissue. Both exposures alone were reported to increase oxidative stress and reduce antioxidant markers in the stomach. Co-exposure was reported to intensify oxidative stress, apoptosis, and histological gastric mucosal injury compared with either factor alone, consistent with a synergistic detrimental effect in this model.
Electromagnetic Field Stimulation Effects on Intrinsically Disordered Proteins and Their Role in Aging and Neurodegeneration
This review discusses preclinical studies suggesting non-ionizing EMF exposures can produce beneficial biological effects, while noting ongoing controversy about mechanisms. It reports evidence of EMF-associated conformational changes in intrinsically disordered proteins relevant to neurodegeneration and describes RF exposure conditions that activate proteostasis and autophagy in cell and animal models. The authors propose a quantum-biophysical framework involving the water-protein interface and suggest potential human applications within regulatory safety thresholds.
RF-EMF Exposure Assessment: Comparison of Measurements in Airports and Flights with and Without Wi-Fi Service
This exposure assessment used personal exposimeters to measure RF-EMF levels in the 2.4 GHz and 5.85 GHz Wi-Fi bands in airport terminals and during four international flights, including flights with and without onboard Wi-Fi service. Reported mean exposures varied by route but were described as substantially below an international reference level (10 W/m²). The authors conclude exposure is low while also recommending ongoing monitoring and precaution due to potential health concerns mentioned as emerging evidence.
