Researchers exposed adult male Wistar rats to 50 Hz extremely low-frequency magnetic fields at 1, 1.5, and 2 mT for 4 hours per day, 5 days per week for 30 days. The study found that different exposure levels caused increases in calcium levels and apoptosis in the rat brain. As the magnetic field strength increased, apoptosis and calcium levels in brain tissues also increased. The researchers concluded that the exposure caused neurodegeneration, increased apoptosis, and increased calcium concentration.

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.

Eighty rats were divided into four exposure groups and a control group, and the treatment groups were exposed to 50-Hz magnetic fields at 1, 100, 500, and 2000 μT for 2 hours daily over 60 days. All rats were immunized with human serum albumin on days 31, 44, and 58. AID expression significantly decreased at 1 μT, Bcl-6 expression did not change, and serum IL-6 increased only in the 500 μT group after immunization.

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.

Male Sprague Dawley rats were divided into four groups: control, RFR exposure, paricalcitol treatment, and combined RFR plus paricalcitol. No significant differences were found in seminiferous tubule diameters or germinal epithelial thicknesses among groups. Ultrastructural changes observed in the seminiferous tubule and Leydig cells in the RFR group were decreased in the RFR plus paricalcitol group. The RFR plus paricalcitol group showed increased Johnsen Score, Ki67, p63 immunoreactivity, SOD and CAT activities, and decreased MDA levels compared with the RFR group.

Researchers exposed Chinese hamster ovary cells to a non-toxic dose of 15-nm gold nanoparticles for 48 hours and then to 900 MHz GSM radiofrequency radiation for 24 hours. The conditioned medium from these cells was transferred to new bystander cells, and cell death, DNA breaks, oxidative stress, and COX-2 expression were measured. RFR increased metabolic death in GNP-treated cells, while colony formation was reduced in bystander cells and RFR-exposed cells regardless of GNP presence. ROS levels were significantly lower in GNP-treated cells, but RFR-induced DNA breaks and micronuclei frequencies were not significantly affected by GNP.

Researchers exposed Chinese hamster cells to 900 MHz cell phone radiation in the presence of gold nanoparticles, then transferred the culture medium to unexposed 'bystander' cells. They found that radiation created harmful effects in both directly exposed cells and bystander cells, with gold nanoparticles changing how these effects occurred.

CT irradiation had gross effects on platelets, white blood cell counts, memory, hepatic and testicular histoarchitectures compared to the 5 GHz-only group. The 5 GHz-only group showed loss of p53 (exons 5–7) gene bands and increased micronucleated polychromatic erythrocyte count.

Researchers exposed male rats to 1800 MHz radiofrequency radiation (cell phone frequency) for one hour daily over 30 days, finding it caused testicular damage including cellular changes and increased oxidative stress. When rats received paricalcitol (a vitamin D compound) alongside radiation exposure, the testicular damage was significantly reduced. This suggests certain compounds might help protect reproductive organs from cell phone radiation effects.

Weaned Wistar rats were divided into four groups and exposed to EMF (1,760 MHz, 2 h/day) and/or 15% fructose solution for 8 weeks. In the hypothalamic tissue of the combined exposure group, expressions of SIRT1, FOXO1, p-PI3K, p-AKT, Complex III, UCP2, MnSOD, and catalase and activities of OXPHOS and GSH were significantly decreased compared to the normal, EMF-only, and fructose-only groups. In hepatic tissue of the combined exposure group, expressions of p-AMPKα, SIRT1, FOXO1, IRS1, p-PI3K, Complex I, II, III, IV, V, UCP2, and MnSOD and activities of OXPHOS, SOD, catalase, and GSH were significantly reduced compared to the normal group.

Researchers exposed growing rats to mobile phone radiation (1,760 MHz) and high-fructose diets for 8 weeks, finding that the combination significantly disrupted metabolic regulation in the brain and liver. The dual exposure impaired insulin signaling, mitochondrial function, and antioxidant defenses more severely than either stressor alone. This suggests that common modern exposures may work together to increase metabolic dysfunction risk during critical developmental periods.

Researchers investigated the effects of 50 and 60 Hz magnetic fields on ROS production, DNA damage, DNA repair, and gene expression in human SH-SY5Y neuroblastoma cells. Cells were exposed to 100 µTRMS magnetic fields for 24 hours, then assayed or treated with menadione before assay. There was suggestive evidence of a low-magnitude increase in ROS-related gene expression immediately after exposure, and 50 Hz fields reduced menadione-induced ROS levels. Magnetic field exposures did not affect cytosolic superoxide levels, DNA damage, or DNA repair rates. No firm evidence was found for differential effects between 50 and 60 Hz fields.

Researchers exposed fruit flies to simulated 3.5 GHz radiofrequency electromagnetic radiation at intensities of 0.1, 1, and 10 W/m². Exposure increased early pupation and eclosion rates and shortened the mean development time. In larvae, heat shock protein and immune gene expression rose, oxidative stress enzymes increased, and microbial diversity fell while Acetobacter and Lactobacillus genera increased.

Researchers exposed two-week-old immature male chickens to non-thermal low-level 2.45 GHz microwave radiation for two hours per day over 30 days. Exposed chickens showed decreased testicular weight, volume, and gonado-somatic index, as well as a substantial reduction in seminiferous tubule diameter. Radiation exposure increased oxidative stress parameters, increased IL-1β immunoreactivity, decreased IL-10 immunoreactivity, and reduced ERα expression in testes.

Researchers exposed young male chickens to WiFi-frequency radiation (2.45 GHz) for 2 hours daily over 30 days and found significant damage to their reproductive systems. The radiation caused testicular shrinkage, increased inflammation, and reduced hormone receptor activity linked to fertility. This study reveals concerning biological mechanisms by which common wireless frequencies may impact male reproductive health.

Researchers exposed young male chickens to 2.45 GHz microwave radiation (the same frequency as WiFi and microwave ovens) for 2 hours daily over 30 days. The radiation caused testicular shrinkage, increased inflammation, and reduced hormone receptor activity linked to male fertility. This study provides biological evidence that common microwave frequencies may impair reproductive development.

Researchers assessed short-term behavioural responses of 15 juvenile thornback rays to direct and alternating 50 Hz uniform 450-μT magnetic fields using a 1-hour focal-sampling design. Magnetic fields were controlled in laboratory conditions with a custom-made Helmholtz coil device. Behavioural responses did not significantly differ between control and exposed rays during the morning period. Rays exposed to direct current magnetic fields increased their activity during the midday period. Alternating current exposure produced synchronisation patterns with high inter-individual variance.

Researchers exposed human HEK293 cultured cells to a 1.8 GHz carrier frequency at amplitudes typical of household telecommunications. ROS concentrations increased significantly after 15 minutes of exposure and were localized to both nuclear and cytosolic compartments. qPCR analysis revealed altered gene expression of anti-oxidative enzymes SOD, GPX, and CAT, and oxidative enzyme Nox-2. Multiple genes responsive to static magnetic fields were also regulated by RF, suggesting common response mechanisms. Many RF effects showed evidence of hormesis with biphasic dose-response curves and blind spots at certain amplitudes.
