Researchers exposed rats to 50 Hz ELF-EMF at 1 and 7 mT for 1 hour per day over 7 days, repeated the procedure three times, and measured adrenaline, noradrenaline, MHPG, and β2-adrenergic receptor expression. After each exposure, some rats underwent a behavioural test to assess stress response to subsequent stress factors. ELF-EMF at 1 mT induced adaptive changes in the noradrenergic locus coeruleus system. Exposure to 7 mT increased stress system activity, causing sensitization to a different stress factor, profoundly decreased β2-adrenergic receptor levels, and moderately increased anxiety-related behaviour.

After four weeks the offspring were sacrificed and hippocampal, kidney, and liver tissues were examined for injury. EMF exposure increased necrotic areas in the hippocampus, hyperemia and necrosis in the kidneys, and degeneration in the liver compared with the group that received both EMF and curcumin. Daily curcumin during pregnancy prevented these tissue injuries in the fetuses.

The study examined RF-EMF effects on lettuce (Lactuca sativa) in indoor and outdoor settings using DECT (1890–1900 MHz) and Wi-Fi (2.4 GHz and 5 GHz) frequencies. Under greenhouse conditions, RF-EMF had only a minor impact on fast chlorophyll fluorescence kinetics and did not affect flowering time. In field conditions, RF-EMF exposure significantly reduced photosynthetic efficiency, accelerated flowering, down-regulated VDE and ZEP genes, and lowered FV/FM and NPQ under light stress.

Researchers exposed 5-week-old male Wistar rats to a 2115 MHz RF-EMR signal at 1.51 W/kg SAR for 8 hours. Exposed rats showed higher lipid peroxidation, carbon-centered lipid radicals, and single-strand DNA damage in the brain. The number of BrdU-positive cells in the dentate gyrus decreased, indicating reduced neurogenesis. RF-EMR exposure caused degenerative changes and neuronal loss in dentate gyrus neurons but not in CA3, CA1, or cerebral cortex neurons.

Researchers exposed young rats to cell phone radiation at 2115 MHz for 8 hours continuously and found significant brain damage including DNA breaks, reduced formation of new brain cells, and neuronal death in the hippocampus. The radiation caused oxidative damage and specifically harmed the brain region critical for learning and memory.

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.

Researchers exposed pregnant rats to 900, 1800, and 2100 MHz EMF radiation for 6, 12, or 24 hours per day over 20 days. After birth, six male pups per group were randomly selected for histopathological and biochemical analysis of myocardial tissue. Myocardial damage was greatest in the 2100 MHz 24-hour group, which also had higher MDA and lower GSH levels. At 1800 MHz, the 24-hour exposure group showed greater damage, higher MDA, and lower GSH compared to shorter durations. The authors concluded that myocardial tissue is more affected by long-term high-frequency EMF exposure and raised concerns about 5G technology.

RF and BC induced moderately significant cell damage at 8 or 24 hours and much greater damage after 48 hours and higher BC dose, and an antiproliferative effect increased with exposure time and dose. Oxidative stress and ROS production increased with radiation time, BC dose, and their combination. Both radiation and BC separately and jointly triggered necrosis and apoptosis, with BCL2a gene expression activated after 24 hours and FASR and caspase-3 activation after 48 hours.

Researchers exposed human immune cells to 2.45 GHz radio frequency radiation (WiFi frequency) combined with black carbon particles from air pollution. The combination caused significant cell damage, triggered cell death pathways, and increased oxidative stress, with effects worsening over longer exposure times.

Researchers exposed pregnant rats to cell phone frequencies (900, 1800, and 2100 MHz) for up to 24 hours daily during pregnancy, then examined heart tissue in newborn pups. Higher frequencies and longer exposure times caused more severe heart damage and oxidative stress, with 2100 MHz (5G frequency) showing the worst effects. The findings suggest that prenatal EMF exposure may harm developing hearts.

Researchers exposed rats to S-band microwave radiation (30 mW/cm² for 35 minutes) to simulate occupational exposure conditions. The study found significant heart damage including disrupted muscle fibers, mitochondrial dysfunction, and oxidative stress, plus psychological effects like anxiety and depression. This suggests that high-power microwave exposure can cause both physical heart damage and mental health impacts.

Researchers exposed zebrafish embryos at 3 hours post-fertilization to a 50-Hz magnetic field at intensities of 100, 200, 400, and 800 μT for 1 hour or 24 hours daily over 5 days. Magnetic field exposure did not affect basic development parameters including hatching rate, mortality, and malformation rate. Exposure to 200 μT magnetic field significantly induced spontaneous movement hypoactivity in zebrafish larvae. Histological examination revealed brain morphological abnormalities including condensed cell nucleus and cytoplasm and increased intercellular space. Exposure to 200 μT magnetic field inhibited syn2a transcription and expression and increased reactive oxygen species levels.

Researchers exposed developing zebrafish to 50 Hz magnetic fields (the same frequency as power lines) and found that exposure reduced the fish's spontaneous movement behavior. The magnetic fields increased harmful reactive oxygen species and decreased production of syn2a, a protein crucial for nerve function and movement.

Exposed MDA-MB-231 cells had higher viability, more live cells, and longer, denser filopodia than unexposed cells. ELF-MF also raised mitochondrial ROS levels and altered mitochondrial morphology in these cells. Proteomic analysis found 328 proteins changed in MDA-MB-231 cells and 242 in MCF-10A cells, with enrichment in focal adhesion and mitochondrion pathways. The exposure reduced adhesion and increased migration and invasion of MDA-MB-231 cells, while transcription factors linked to cellular reprogramming were upregulated in MDA-MB-231 and downregulated in MCF-10A.

Researchers exposed fenugreek seeds to 900 MHz electromagnetic radiation (similar to cell phone frequencies) for varying durations up to 8 hours daily for a week. The study found that longer exposures significantly reduced seed germination, stunted plant growth, caused oxidative stress through lipid damage, and triggered DNA damage in plant cells.

Researchers exposed mice continuously for 16 weeks to 2.45 GHz RF radiation from a household Wi-Fi router and a laboratory device, comparing them to a sham-exposed group. Mice underwent behavioral tests including open-field and Y-maze before and after exposure, and brains were examined for histopathology and DNA methylation. Exposure increased locomotor activity but did not produce significant structural or morphological brain changes. Global DNA methylation was lower in exposed mice than in sham mice.

Researchers exposed mice to WiFi radiation (2.45 GHz) for 16 weeks using both household routers and laboratory equipment to simulate real-world conditions. The exposed mice showed increased movement activity and reduced DNA methylation in their brains, but no visible structural brain damage. This suggests WiFi radiation may cause subtle biological changes even without obvious tissue damage.

Twenty-one healthy volunteers were exposed to a GSM signal at 900 MHz with specific absorption rates of 0.49 W/kg (10 g tissue) and 0.70 W/kg (1 g tissue). Delta and beta rhythms of resting EEG were not affected by the exposure. Theta brainwaves were significantly modulated during exposure, and this modulation depended on whether eyes were closed or open.

Researchers exposed 21 healthy volunteers to 900 MHz cell phone radiation and measured their brain waves using EEG. They found that theta brainwaves were significantly altered during exposure, with the effect depending on whether participants had their eyes open or closed. This is the first study to show that cell phone radiation can modify specific brain wave patterns in a way that depends on visual attention state.

Researchers analysed DNA methylation profiles of cervical cancer and neuroblastoma cell lines exposed to 900 MHz GSM-modulated radiofrequency electromagnetic fields. Radiofrequency exposure did not affect the DNA methylation of Alu elements in any of the cell lines analysed. It influenced DNA methylation of LINE-1 and ribosomal repeats in terms of average profiles and organisation of methylated and unmethylated CpG sites, in different ways in each of the three cell lines studied.
