Researchers exposed pregnant rats to 1800 MHz cell phone radiation and 2400 MHz WiFi signals, then tested their offspring's behavior and brain development. The exposed pups showed altered movement patterns, changed brain chemistry, and different developmental timing compared to unexposed controls. The study suggests prenatal EMF exposure may affect how the brain develops during critical early periods.

Researchers applied a 2-h head-only GSM-1800 MHz exposure to rats with LPS-induced acute neuroinflammation, to healthy rats, and to transgenic hSOD1 G93A rats modeling presymptomatic ALS. Gene responses were measured 24 hours later in a motor area of the cerebral cortex where the mean SAR was 3.22 W/kg. In LPS-treated rats, RNA-seq revealed significant but moderate gene expression changes affecting 2.7% of expressed genes, including neuronal and glial genes and genes involved in protein ubiquitination or dephosphorylation.

Researchers randomly divided 120 Wistar rats into ten groups of 12 and exposed them to RF-EMF, 10 cGy x-rays, 8 Gy x-rays, combinations of these, or sham exposure. They measured liver enzymes in serum, as well as histopathological changes and oxidative stress markers including MDA, nitric oxide, antioxidant power, total thiols, and PCO. Gamma-glutamyltransferase was not associated with irradiation, but aspartate transaminase, alanine transaminase, and alkaline phosphatase showed some association. MDA and PCO levels increased after 8 Gy irradiation, but pre-exposure to RF-EMF modulated these changes, and lobular inflammation frequency was associated with the intervention type.

Pregnant mice were exposed to Wi-Fi signal (2.4 GHz) for 2 and 4 hours. Placenta tissues were examined for MDA and SOD levels, and gene expression of SOD, CDKNA1, GADD45a, Bax, and Bcl-2 was measured by real-time PCR, while apoptosis was assessed using TUNEL assay. MDA and SOD levels significantly increased in exposed groups (P-value<0.05), and SOD mRNA expression also significantly increased. CDKN1A and GADD45a gene expression increased in exposed groups (P-value<0.05), and apoptosis increased as shown by quantitative PCR and TUNEL assay (P-value<0.05).

Researchers exposed pregnant mice to Wi-Fi signals (2.4 GHz) for 2 and 4 hours and examined the placenta tissue. They found increased oxidative stress, DNA damage markers, and cell death in the placenta after Wi-Fi exposure. This matters because the placenta is crucial for healthy fetal development during pregnancy.

Researchers exposed rats to 900 MHz radiofrequency radiation (the type emitted by cell towers) for four hours daily over 30 days and found it significantly impaired their learning and memory. Rats given vitamin E or a combination of vitamin E and C before exposure were protected from these cognitive effects. The study suggests antioxidant supplementation may counteract some of the biological stress caused by continuous RF radiation exposure.

Researchers exposed 30 adult male Balb/c mice to 2.4 GHz Wi-Fi radiation or sham exposure, with some mice treated with busulfan to induce oligospermia. Low power density Wi-Fi radiation significantly increased sperm concentration in healthy mice and showed greater increase in oligospermic mice with higher exposure.

During all days of pregnancy, rats in the EMF-exposed group were exposed to 900 MHz pulsed-EMF radiation for 6 h per day. The exposure group demonstrated reduced spontaneous firing associated with upward and rightward shift in I/V curve compared to the control rats, and the peak amplitude of the current for the exposure pups also revealed a significant decrement. The reversal potential was +40 mV and +20 mV for the control and RF-EMF groups, respectively and showed significant differences between the two groups.

Researchers exposed male Sprague Dawley rats to radiofrequency radiation at 900, 1800, or 2100 MHz for 2 hours per day for 6 months to study DNA damage and oxidative stress in blood and brain tissue. DNA damage and oxidative stress indicators were found higher in the radiofrequency radiation exposure groups than in the sham-control group. The researchers concluded that 900-, 1800-, and 2100-MHz radiofrequency radiation may cause oxidative damage, induce an increase in lipid peroxidation, and increase oxidative DNA damage in the frontal lobe of rat brain tissues, and that 2100-MHz radiation may cause formation of DNA single-strand breaks.

Researchers exposed honey bee queen larvae to radiation from a common mobile phone device (GSM band at 900 MHz) during all stages of pre-adult development including pupation. After 14 days of exposure, hatching of adult queens was assessed and mating success after a further 11 days. Mobile phone radiation significantly reduced the hatching ratio but not the mating success. When treated queens successfully mated, colony development was not adversely affected.

NASA's SMAP mission conducted a field experiment over two 40-km agricultural domains in Iowa and Manitoba in summer 2016 with airborne PALS flights and intensive ground measurements. The experiment had two observation periods capturing early-season low vegetation and later-season high vegetation conditions. PALS brightness temperature measurements compared to SMAP showed an RMSD of 2.8 K for vertical polarization and 4.0 K for horizontal polarization. Using seasonally variable parameters allowed satisfactory soil moisture retrieval accuracy. The results suggested that rapidly growing vegetation and early-season surface condition changes not captured by the SMAP algorithm caused SMAP retrieval errors.

Twenty-four Wistar albino rats were randomly divided into four groups: control, EMF, luteolin, and EMF + luteolin. EMF exposure reduced Leydig cells, primary spermatocytes, and spermatids, increased SOD activity, and decreased testis wet weight and serum testosterone. Luteolin treatment increased those cell counts, restored testis weight and testosterone, and decreased SOD activity compared with EMF alone.

Researchers exposed rats to 900 MHz electromagnetic fields (similar to cell phone radiation) and found significant damage to testicular tissue, including reduced sperm production cells and lower testosterone levels. However, when rats were given the antioxidant luteolin alongside EMF exposure, most of the harmful effects were prevented or reduced.

Scientists exposed human and rat brain cells to 918 MHz radiofrequency radiation (similar to cell phone frequencies) in the presence of Alzheimer's-related toxic proteins. The EMF exposure reduced harmful cellular damage and oxidative stress caused by these proteins. The researchers suggest this frequency might have therapeutic potential for treating Alzheimer's disease.

Researchers exposed human and rat brain cells (astrocytes) to 918 MHz radiofrequency radiation - the same frequency range as mobile phones - while the cells were under stress from Alzheimer's-related toxins. The EMF exposure reduced harmful cellular damage and oxidative stress caused by these toxins. This suggests mobile phone radiation might have protective effects against Alzheimer's disease processes.

Researchers exposed rats to 900 MHz EMF for 2 hours daily over 8 weeks and measured effects on male reproductive parameters. EMF exposure significantly decreased sperm count, viability and motility and increased sperm deformities. EMF-exposed rats showed significant reductions in serum inhibin B and testosterone along with elevated activin A, follicle-stimulating hormone, luteinizing hormone and estradiol concentrations. Testicular StAR protein, c-kit mRNA expression, and activities of 3β- and 17β-hydroxysteroid dehydrogenases were significantly attenuated after EMF exposure. Spermine administered at 2.5 mg/Kg/day intraperitoneally for 8 weeks prevented EMF-induced alterations in sperm and hormone profiles, StAR and c-kit expression, and androgenic enzyme activities.

Researchers exposed male mice to 905 MHz radiofrequency radiation (similar to cell phone frequencies) for up to 5 weeks, finding significant DNA damage and reduced sperm quality. While sperm could still fertilize eggs, the radiation caused oxidative stress and fragmented sperm DNA at levels comparable to everyday wireless device exposure.

Researchers exposed rats to 900 MHz electromagnetic fields (similar to cell phone frequencies) for 2 hours daily over 8 weeks and found significant damage to sperm quality, hormone levels, and testicular function. However, when rats were given spermine (a natural compound), it protected against most of the EMF-induced reproductive damage. The study suggests EMF exposure disrupts male fertility through oxidative stress and inflammation.

Researchers exposed male rats to 900 MHz electromagnetic fields (similar to cell phone frequencies) for 2 hours daily over 8 weeks and found significant damage to sperm quality, hormone levels, and testicular function. However, when rats were given spermine (a naturally occurring compound), it protected against most of the EMF-induced reproductive damage. This suggests that certain protective compounds might help counteract EMF effects on male fertility.

Researchers exposed rats to 900, 1800, and 2100 MHz radiofrequency radiation for 2 hours daily over 6 months. Exposure increased oxidative stress markers including TOS, OSI, MDA, and 8-OHdG, while decreasing total antioxidant status. DNA damage measured by comet assay showed higher tail intensities in exposed groups.

Researchers exposed rats to cell phone frequencies (900, 1800, and 2100 MHz) for 2 hours daily over 6 months and found significant DNA damage and oxidative stress in testicular tissue. The higher frequencies (1800 and 2100 MHz) caused more severe DNA breaks, while all frequencies increased harmful oxidative markers and decreased protective antioxidants. This suggests prolonged cell phone radiation exposure may damage reproductive tissue at the cellular level.
