Researchers exposed zebrafish embryos to mobile phone radiation at 1800 MHz and 1.13 W/kg for 1 hour daily over 5 days, starting at 1, 6, or 24 hours post-fertilization. No significant changes were observed in survival rate, morphology, oxidative stress, or cortisol levels across any exposure group. However, embryos exposed from 1 hour post-fertilization showed statistically significant reductions in distance travelled and increased yolk sac area compared to controls.

The study assessed the short-term impact of low-intensity 2.45 GHz exposure on young Arabidopsis thaliana plants. Plants were exposed to continuous wave 2.45 GHz microwaves at 1.0 ± 0.1 W m−2 for 48 hours in anechoic chambers. Exposure increased photosynthetic pigments, oxidative stress, guaiacol peroxidase activity, and ascorbic peroxidase activity, while catalase activity decreased. Photosystem efficiency remained unchanged, non-photochemical quenching increased, leaf morphology showed no significant changes, and genomic template stability was unaffected.

Researchers exposed zebrafish embryos to 900 MHz radiofrequency radiation (similar to cell phone frequencies) for 30 or 60 minutes daily during development. They found disrupted genes controlling fat formation and insulin function, along with increased cellular stress markers. The study suggests early-life EMF exposure may contribute to metabolic problems later in life.

Researchers exposed human dermal fibroblasts to continuous and pulsed 1.6 GHz radiofrequency at 0.4 W/kg for 2 hours. Exposure altered heat-shock protein expression, cytoskeletal organization, and increased lysosomes, with autophagosomes only after pulsed exposure. Mitotic spindle anomalies occurred but no significant effects were seen on cell cycle, chromosome segregation, micronuclei, or DNA damage foci.

Researchers exposed mouse testosterone-producing cells (Leydig cells) to radiation from 4G phones and specific frequencies of 1800 MHz and 2450 MHz. After 2 hours of exposure, testosterone production dropped significantly and harmful free radicals increased, while cell survival wasn't affected. This suggests cell phone radiation could contribute to male fertility problems.

Researchers exposed zebrafish embryos to mobile phone radiation (1800 MHz) for one hour daily over five days, starting at different developmental stages. Embryos exposed from the earliest stage (1 hour after fertilization) showed reduced swimming activity and anxiety-like behavior, while later exposures had no effect. The study suggests developing organisms are most vulnerable to RF radiation during their earliest life stages.

Researchers exposed zebrafish embryos to 900 MHz radiofrequency radiation (similar to older cell phone frequencies) for 30 or 60 minutes daily during development. The exposure disrupted genes controlling fat storage and blood sugar regulation, while increasing oxidative stress markers. This suggests RF radiation during early development may contribute to metabolic problems later in life.

Researchers divided 32 adult male Wistar rats into four groups: control, RF-EMF alone, heat stress alone, and RF-EMF combined with heat stress. Rats in the RF-EMF group were exposed for 2 hours daily over 52 days, while the heat stress group received 10 minutes of heat per day for the same period. After 52 days, the combined RF-EMF and heat group showed significant improvements in testis volume, tubular epithelium, interstitium, cell counts, sperm quality, and Leydig cells compared with the heat-only group.

Researchers studied the content of biogenic amines, their precursors, and derivatives in the prefrontal cortex of male Wistar rats exposed to chronic low-intensity electromagnetic fields from a Wi-Fi device during early postnatal development. Changes in dopamine, serotonin, their precursors, and metabolites were established in the prefrontal cortex. These changes determine the development of neurotransmitter disorders in the central nervous system and subsequently behavioral disorders, deterioration of social adaptation, and cognitive abilities.

Twenty-four male Balb/c mice were divided into four groups and the EMF groups were exposed to 2100-MHz EMF for 120 minutes per day over 30 days. After 30 days EMF exposure significantly reduced astrocyte diameter and increased GFAP expression in the cerebellar cortex. Crocin treatment improved astrocyte diameter and normalized GFAP expression.

Researchers exposed twelve pregnant rats and their male newborns to Wi-Fi frequencies at electric field values of 0.6, 1.9, 5, 10, and 15 V/m during gestation and 45 days after birth. Auditory brainstem response testing was performed before exposure and sacrification. Cochlear histopathological examination used immunohistochemistry for caspase-3, caspase-9, and TUNEL staining. Auditory thresholds increased significantly at 5 V/m and above, while apoptotic cell markers showed significant differences at 10 V/m and 15 V/m. All apoptotic indicators increased with electric field magnitude, with caspase-9 showing the strongest effect.

Researchers exposed male rats to cell phone (915 MHz) and WiFi (2450 MHz) radiation for 30 days, finding significant damage to testicular tissue and sperm production. However, when rats were given rosmarinic acid (a natural antioxidant found in herbs like rosemary), it protected against this reproductive damage by reducing oxidative stress.

Researchers exposed pregnant rats and their offspring to WiFi-frequency radiation (2.45 GHz) at various power levels throughout pregnancy and early development. They found that exposure caused hearing loss and triggered cell death in the inner ear, with damage increasing at higher power levels. Even low-level WiFi radiation caused measurable harm to the delicate structures responsible for hearing.

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 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.
