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 used high-throughput RNA sequencing to compare gene expression in E. coli DH5α exposed to 2.4 GHz Wi-Fi radiation and unexposed controls. The analysis identified 101 differentially expressed genes, with 52 up-regulated and 49 down-regulated. Quantitative RT-PCR of selected genes confirmed the sequencing results. Pathway analysis showed that flagellar assembly, chemotaxis, two-component systems, and metabolic pathways were affected.

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.

Researchers exposed fresh adventitious onion roots to continuous electromagnetic fields at 2350 MHz for one, two, or four hours. Cytotoxicity was evaluated through mitotic index, phase index, and chromosomal aberrations, while genotoxicity was assessed via comet assay measuring head DNA, tail DNA, tail moment, and olive tail moment. Mitotic index increased significantly after four hours and chromosomal aberrations increased after two hours or more, while phase index showed no specific changes. Head DNA and tail DNA percentages changed significantly after two and four hours respectively, but tail moment and olive tail moment did not change significantly.

Researchers exposed fresh onion roots to 2100 MHz electromagnetic fields for 1 hour and 4 hours and measured mitotic index, chromosomal aberrations, and DNA damage using the comet assay. After 4 hours of exposure, mitotic index and chromosomal aberration percentage increased significantly compared to controls. DNA damage was indicated by a significant decrease in head DNA and increase in tail DNA after 4 hours, while tail moment and olive tail moment did not change significantly. Post-exposure evaluation after 24 hours showed no significant recovery or change.

Researchers exposed rats to cell phone radiation at 900, 1800, and 2100 MHz frequencies 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 the most severe effects, including DNA strand breaks and reduced antioxidant defenses. This suggests prolonged cell phone use may pose reproductive health risks for men.

A Wi-Fi router was used as a source of microwaves and bacterial cells were exposed continuously for 24 and 48 hours. Antibiotic susceptibility was tested by disc diffusion on Müller Hinton agar, motility of Escherichia coli O157H7 was assessed on motility agar, and metabolic activity and biofilm formation were measured with MTT assay and crystal violet quantification. Exposure altered motility and antibiotic susceptibility of Escherichia coli O157H7, did not change antibiotic susceptibility of Staphylococcus aureus or Staphylococcus epidermis, and increased metabolic activity and biofilm formation in Escherichia coli O157H7, Staphylococcus aureus and Staphylococcus epidermis.

Researchers exposed adult male Wistar albino rats to electromagnetic field radiation for 60 minutes per day for 28 days and assessed spinal cords using stereological, biochemical, and histological methods. The electromagnetic field group had fewer motor neurons and higher superoxide dismutase levels than the control group. Thymoquinone treatment increased motor neuron numbers and decreased superoxide dismutase activity compared to the electromagnetic field group.

Turkish researchers exposed rats to 900 MHz cell phone radiation for one hour daily over 28 days and found significant damage to spinal cord motor neurons. The study also tested whether thymoquinone, a natural antioxidant compound, could protect against this damage and found it successfully prevented the neurological harm. This suggests cell phone radiation may affect the nervous system beyond just the brain.

Three-week-old male Sprague Dawley rats were divided into control, pseudo-exposed, and EMF groups, with the EMF group receiving a 900-MHz EMF for 1 hour per day for 25 days. Following exposure, behavioral tests were performed for seven days before the animals were euthanized and their brains removed. Brain sections were stained with toluidine blue and pyramidal neuron numbers in CA1, CA2-3, and hilus and granule neuron numbers in the dentate gyrus were estimated using optical fractionation. The EMF group showed statistically higher numbers of both pyramidal and granule neurons than the pseudo-exposed group, and histopathological examination revealed cytoplasmic disruption in those neurons.
