Researchers conducted a randomized, triple-blind, crossover study with 44 healthy young volunteers exposed to 3.5 GHz signals at 1 to 2 V/m. Each session included baseline, exposure, and postexposure phases with seven runs of electrodermal activity recordings stimulated by beeps and skin temperature measurements at the hand, head, and neck. The study suggests a slight increase in head and neck temperature and minimal modulation of electrodermal metrics after exposure, though results remain within normal physiological range and could reflect an uncontrolled variable.

Female rats were exposed to MWR at a frequency of 2.45 GHz for 2 hours daily throughout pregnancy. The study examined the rostral migratory stream and the dentate gyrus of the hippocampus for cell proliferation and death, and also assessed nitrergic neuron differentiation in the RMS. Prenatal MWR exposure caused significant changes in the numbers of proliferating and dying cells that varied by offspring age and brain region. MWR attenuated the maturation of nitrergic neurons in the RMS in both juvenile and adult rats. Morphological alterations in neurogenesis were accompanied by changes in animal behavior.

The study used 20 female and 20 male Wistar Albino rats divided into four groups with different exposure patterns to 6 GHz RF-EMF at 0.054 W/kg. Rats were exposed for 4 hours per day for 6 weeks before mating, and pregnant rats in Group-II and Group-III were exposed for 4 hours per day for 18 days of gestation. Fetal weight, body lengths, and bone measurements all increased significantly in every exposure group compared with controls.

Slovak researchers exposed pregnant rats to 2.45 GHz microwave radiation (WiFi frequency) for 2 hours daily throughout pregnancy. Their offspring showed significant disruptions in brain cell growth and development in key regions responsible for learning and memory, along with behavioral changes that persisted into adulthood.

Researchers exposed perinatal rats to tap water, L-arginine, or N-methylarginine, with half of each group also receiving a 7-Hz square-wave EMF at 5, 50, or 500 nT for 2 to 14 days after birth. Brains were harvested in adulthood at a mean age of 568.17 days and stained with Toluidine Blue O for neuronal counts in the hippocampus, cortices, amygdala, and hypothalamus. Histological analysis revealed a main EMF effect of increased neuronal counts in the secondary somatosensory cortex at low intensities, a significant increase in the left CA3 region in exposed females, and a significant increase in the right entorhinal cortex in exposed males.

Researchers exposed rats to 7 Hz electromagnetic fields during early brain development and found increased neuron counts in specific brain regions, with effects varying by sex. Male and female rats showed different patterns of brain changes, particularly in the hippocampus and sensory cortex areas. The findings suggest that low-frequency EMF exposure during critical developmental periods can alter brain structure in ways that persist into adulthood.

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.
