Researchers exposed brain-like cells and immune cells to 2.45 GHz WiFi radiation for 24 hours, finding it reduced cell survival and caused cellular damage. However, a low dose of sulforaphane (a compound from broccoli) protected the cells from this radiation damage. The protective effect only worked at low doses - higher concentrations of sulforaphane actually made things worse.

Researchers exposed 30 Aedes aegypti eggs to radiofrequency radiation at baseline, 900 MHz, and 18 GHz, with each frequency tested in triplicate. They assessed hatching responses, development times, larval numbers, and pupation periods until adult emergence. The 900 MHz group showed the highest hatching rate at 79 ± 10.54% and the lowest adult emergence rate at 33 ± 2.77%, with a significant difference between groups (p = 0.03).

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.

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.

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 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 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.

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.

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 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 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.

The study used prepubertal male rats exposed to 2.45 GHz RF radiation at varying electric field intensities. The exposure groups included electric field strengths of 0.6, 1.9, 5, 10, and 15 V/m, with daily 1-hour exposures for 45 days. Exposed rats showed elevated malondialdehyde (MDA) and decreased glutathione (GSH) levels in testicular tissue. Histological analysis revealed distinct alterations in testicular tissue compared to controls.

Researchers exposed young rats to 2.45 GHz radiation (WiFi frequency) at different intensities for 45 days to study effects on developing reproductive tissue. The study found that stronger radiation caused increased oxidative damage and structural changes in testicular tissue, with the highest exposure level (15 V/m) producing significant harmful effects.
