Effect of 2850 MHz electromagnetic field radiation on the early growth, antioxidant activity, and secondary metabolite profile of red and green cabbage (Brassica oleracea L

Unknown authors · 2024

Researchers studied the impact of 2850 MHz electromagnetic field radiation on red and green cabbage seedlings, exposing them daily for seven days to homogeneous EMF-r for one, two, or four hours. Exposure caused dose-dependent reductions in root length, shoot length, and biomass in both cultivars compared with controls. Chlorophyll and carotenoid contents decreased significantly in both red and green cabbage. Phenolic, flavonoid, and anthocyanin contents increased with exposure duration in both cultivars. EMF-r produced oxidative stress shown by dose-dependent increases in total antioxidant activity, DPPH activity, H2O2 content, and MDA content, while antioxidant enzyme activities increased significantly.

Diminishes Hippocampal Apoptosis Induced by Microwave Radiation by Acetylcholinesterase Dependent Neuro-Inflammatory Pathway in Male Coturnix coturnix Japonica

Gupta V, Srivastava R · 2024

The study used a control group, a microwave radiation group exposed for 2 h/day for 30 days, an ashwagandha group given 100 mg/day/kg body weight, and a combined exposure group. Microwave radiation increased serum corticosterone levels, disrupted cholinergic balance, and induced neuro-inflammation. Neuro-inflammation led to oxidative stress, as shown by decreased activity of the antioxidant enzymes SOD, CAT, and GSH. Microwave radiation also caused a significant decline in nissil substances in the hippocampus, indicating neurodegeneration through oxidative stress mediated hippocampal apoptosis. Ashwagandha reduced ROS production by increasing ROS-scavenging enzyme activity and decreased caspase-3 and caspase-7 expression, promoting neuronal health.

Evaluation of Oxidative Stress and Genetic Instability Among Residents Near Mobile Phone Base Stations in Germany

Gulati S et al. · 2024

Researchers identified two neighboring housing estates with relatively low or high RF-EMF from nearby mobile phone base stations and 24 healthy adults who had lived in their homes for at least five years volunteered. Homes were surveyed for EMF and blood samples were tested for oxidative status, DNA alterations, chromosomal damage, and cancer-related genetic markers such as MLL gene rearrangements. Long-term exposure had no measurable effect on MLL gene rearrangements or c-Abl-gene transcription, and lipid oxidation and oxidative DNA lesions were higher but not statistically significant. Dicentric chromosomes, chromatid gaps, chromosomal fragments, and total chromosomal aberrations were significantly higher in the exposed group. No potential confounder interfered with these findings.

Biological effects of electromagnetic fields on insects: a systematic review and meta-analysis

Thill A, Cammaerts MC, Balmori A · 2023

This systematic review summarizes the results of studies investigating the toxicity of electromagnetic fields in insects. The review focuses on detrimental effects from technological infrastructure, particularly power lines and cellular networks. Biological effects of non-thermal EMF on insects are clearly proven in the laboratory but only partly in the field. The authors state that extrapolating from laboratory results warrants increasing the threat level of environmental EMF impact on insects.

Unknown authors · 2023

The review examines experimental, epidemiological, and clinical evidence on biological impacts of wireless technology on children. The review reports that more than half of toddlers regularly use screens contrary to pediatric guidelines, and that early device use is linked to speech delays, technoference, and addiction-like behaviors. The authors recommend an ALARA approach for microwave radiation and an independently funded research program on long-term physical and psychological impacts.

The European Union assessments of radiofrequency radiation health risks – another hard nut to crack (Review)

Nyberg et al · 2023

A 2017 article described the WHO as unwilling to acknowledge health effects from wireless phones. The WHO was characterized as 'A Hard Nut to Crack'. The EU is following the WHO's approach and has not acknowledged any risks from radiofrequency radiation despite increasing evidence. Seven appeals by scientists and medical doctors have requested a halt to 5G rollout since September 2017. The appeals have been ignored.

(2023) An Exposimetric Electromagnetic Comparison of Mobile Phone Emissions: 5G versus 4G Signals Analyses by Means of Statistics and Convolutional Neural Networks Classification

Miclaus et al · 2023

Researchers used signal and spectrum analyzers with statistical functions to compare exposimetric descriptors of emissions from file download, file upload, video streaming, and video calls on 4G and 5G networks. The method measured highest and lowest electric field strengths at 10 cm from the phone and highlighted prevalent power distribution functions. A convolutional neural network classified the emissions with very high accuracy, enabling traceability of human exposure dynamics.

(2023) Genotoxic risks to male reproductive health from radiofrequency radiation

Kaur et al · 2023

Mobile phones, televisions, microwaves, radio, and wireless devices employ radiofrequency waves to which everyone is exposed. Excessive and long-term exposure to non-ionizing radiation may cause genetic health effects on the male reproductive system, which could be a primitive factor to induce cancer risk. The review incorporates both in vitro and in vivo studies of radiofrequency radiation effects, including DNA damage, micronuclei formation, chromosomal aberrations, SCE generation, ROS generation, oxidative stress, base adduct formation, sperm head DNA damage, and DNA-protein cross-linking.

Lai H, Levitt B. (2023) Cellular and molecular effects of non-ionizing electromagnetic fields

Unknown authors · 2023

The cellular stress response is a set pattern of cellular and molecular responses to environmental stressors such as heat, ionizing radiation, and oxidation. This response is triggered by cellular macromolecular damage in proteins, lipids, and DNA with the goal of repairing and returning cell functions to homeostasis. The concept that biological response to EMF is a cellular stress response explains many observed effects of EMF, such as nonlinear dose- and time-dependency, increased and decreased risks of cancer and neurodegenerative diseases, enhanced nerve regeneration, and bone healing.

Extremely Low Frequency-Electromagnetic Fields (ELF-EMF) Can Decrease Spermatocyte Count and Motility and Change Testicular Tissue

Unknown authors · 2023

The study used sixty male Sprague-Dawley rats divided into six groups with different ELF-EMF exposure durations. Sperm count and motility were significantly lower in rats exposed for 1 hour per day for 52 days, 4 hours per day for 52 days, and 4 hours per day for 5 days compared with sham-exposed rats. Serum testosterone decreased significantly in rats exposed for 4 hours per day for 5 days. The volume of seminiferous tubules, their epithelium, and interstitial tissue decreased significantly after 4 hours per day for 5 days of exposure. Tubule length was reduced by 18% in the same exposure group.

Migratory bats are sensitive to magnetic inclination changes during the compass calibration period

Schneider WT, Holland RA, Keišs O, Lindecke O · 2023

Researchers investigated how an altered magnetic field at sunset changes the nocturnal orientation of Pipistrellus pygmaeus by exposing bats to the natural magnetic field, a 120° horizontal shift, or the same shift combined with a reversal of inclination from 70° to −70°. Bats exposed to the 120° shift oriented unimodally northward, while controls showed a bimodal north–south distribution. Bats exposed to both the 120° shift and reversed inclination showed orientation indistinguishable from a uniform distribution. The results suggest that migratory bats calibrate the magnetic field at sunset and are sensitive to the angle of magnetic inclination.

A mathematical model and experimental procedure to analyze the cognitive effects of audio frequency magnetic fields

Unknown authors · 2023

Researchers introduced a mathematical model and experimental tool to analyze memory performance in 65 young healthy subjects. Working memory was assessed using the Sternberg test while one subgroup received a ~0.1 μT audio frequency magnetic stimulus applied to both sides of the head near the temporal–parietal area and the other subgroup received a sham stimulus. The model revealed deterioration of working memory that could affect 32% of its operability.

Extremely Low-Frequency Electromagnetic Stimulation (ELF-EMS) Improves Neurological Outcome and Reduces Microglial Reactivity in a Rodent Model of Global Transient Stroke

Unknown authors · 2023

Researchers evaluated ELF-EMS at 13.5 mT/60 Hz in a rodent model of global transient stroke, measuring neurological outcome, behavior, neuronal survival, and glial reactivity. ELF-EMS improved neurological scores and behavior in the ischemia-reperfusion model. The treatment also improved neuronal survival and decreased glial reactivity in the hippocampus, with microglia showing the first signs of treatment effect. In vitro, ELF-EMS decreased LPS and ATP-induced microglia migration in scratch and transwell assays. In hippocampal brain slices, ELF-EMS reduced microglial reactivity, improved neuronal survival, and modulated inflammation-related markers.
