Researchers exposed adult rats to 2100 MHz radiofrequency radiation (the frequency used by 3G cell phones) for either 1 week or 10 weeks, 2 hours daily. Short-term exposure delayed auditory brainstem responses and caused brain oxidative damage, while longer exposure with rest days showed no harmful effects. This suggests acute cell phone radiation exposure may temporarily impair hearing function.

Researchers exposed adult zebrafish to Wi-Fi radiation (2.45 GHz) for 4 hours daily over 30 days and found significant behavioral problems, movement changes, reduced brain chemicals, and increased oxidative stress. This study adds to growing evidence that chronic Wi-Fi exposure may harm brain function in vertebrates.

The study aimed to test whether GSM radiofrequency exposure modulates brain functional connectivity. Healthy young adults were exposed to GSM signals at 900 MHz, modulated at 217 Hz with a maximum power of 2 W. Real exposure produced significant alterations in intra-hemispheric functional connectivity, especially in right-hemisphere regions such as the transverse temporal, entorhinal, insula, and posterior cingulate.

Researchers exposed honey bee workers to 900 MHz electromagnetic fields of varying intensities and durations in wooden cages. Behavior was analyzed by computer program immediately after exposure and again seven days later. The radiofrequency field affected bee behavior compared to unexposed controls, though not all results were statistically significant. Significant effects were seen seven days after exposure in walking, flight, and individual contact.

Sixty healthy women and men aged 60 to 80 years completed four attentional tasks in nine sessions while exposed to GSM 900 MHz, TETRA 385 MHz, or sham exposure. Two of 16 performance measures were significantly affected by exposure in women only, with worse accuracy in an n-back task under GSM exposure in the easier version and under TETRA exposure in the highest level. Performance of women and men did not differ significantly overall, and only one significant sex-exposure interaction was observed under TETRA exposure, indicating better performance in men and worse in women compared to sham. The researchers concluded that overall cognitive performance of healthy elderly participants was not affected by short-term RF-EMF exposure.

Researchers established a dual-frequency EMR mouse model at 0.8/2.65 GHz. Exposure to this dual-frequency EMR significantly induced anxiety-like behavior in mice. Molecular experiments showed a significant decrease in CB1R levels in the medial prefrontal cortex along with a notable reduction in the endogenous cannabinoids 2-arachidonoylglycerol and anandamide, indicating downregulation of the entire endocannabinoid system. Overexpressing and knocking down CB1R in the medial prefrontal cortex confirmed that increasing mPFC CB1R levels reduced anxiety-like behavior while decreasing mPFC CB1R levels exacerbated it. Dual-frequency EMR also induced changes in the endocannabinoid system in the basolateral amygdala, and female mice exhibited similar behavioral phenotypes and molecular mechanisms.

Nineteen healthy participants with a mean age of 36.5 years were exposed to 5G mobile phone exposure at 3.6 GHz and 0.0030 W/m2 for 5 and 20 minutes. Corticospinal excitability, intracortical facilitation, short intracortical inhibition, and long intracortical inhibition were measured with transcranial magnetic stimulation before and after exposure. A repeated-measures ANOVA found no significant interactions between exposure condition and time for any of these measures (all p > 0.15). Bayesian analyses gave Bayes factors close to 1, indicating inconclusive evidence for both the null and alternative hypotheses.

Researchers exposed developing rats to 900MHz cell phone radiation at levels considered safe by current regulations (0.08 and 0.4 W/kg SAR). The study found significant changes in brain development, including reduced brain growth factors, fewer new brain cells, disrupted nerve connections, and DNA damage in neural stem cells. These effects occurred at exposure levels typical of everyday cell phone use.

Researchers created a 3D digital twin of an adult fruit fly using micro-CT scans and used it in numerical simulations to estimate absorbed power at 3.6 GHz. They exposed adult Drosophila melanogaster to 3.6 GHz fields for 5 days at 5.4 to 9 V/m (3.56 to 9.88 nW absorbed) and measured locomotor activity. They also exposed flies for 48 hours at an absorption level of 1.91 mW and measured fecundity. No effects were found on either locomotor activity or fecundity.

Researchers exposed pregnant rats to 3.5 GHz radiofrequency radiation (similar to 5G frequencies) and found that their male offspring developed severe testicular damage by adulthood. The exposed rats showed reduced sperm production, increased DNA damage, and higher rates of cell death in reproductive tissues compared to unexposed controls.

Researchers exposed female rats to 700MHz 5G radiation for either 10 days (6 hours daily) or 60 days (4 hours daily) to study reproductive effects. While hormone levels and DNA remained mostly normal, long-term exposure caused oxidative stress in ovaries and tissue changes including cystic follicles. The findings suggest prolonged 5G exposure may harm female reproductive organs through cellular damage.

Researchers exposed male rats to 5G frequencies (3.5 GHz and 24 GHz) for 60 days and found significant damage to sperm quality and testicular function. Both frequencies reduced sperm motility and concentration, with 24 GHz causing more severe effects including immune system disruption. The damage worsened with longer daily exposure times.

Researchers exposed pregnant rats to 900-MHz EMF for 2 hours daily during three gestational periods: GD 1–7, GD 8–14, and GD 15–21. Female offspring were sacrificed on postnatal day 28 and hippocampal PARP-1 and Caspase-3 expression was evaluated. Pyramidal neurons in the CA region appeared normal after GD 1–7 exposure but were darkly stained and shrunken after GD 15–21 exposure. The GD 15–21 exposure group showed strong PARP-1 and Caspase-3 immune reactivity in CA and dentate gyrus cells with higher H-scores. The authors concluded that EMF at GD 15–21 triggered hippocampal neuron death by activating PARP-1 and Caspase-3.

Histological examination revealed vacuolation in the testes and corpus epididymis of both exposed groups and multifocal atypical hyperplasia in the seminal vesicle. Seminiferous tubule diameter decreased gradually in both exposed groups with a substantial decrease in the 24-hour group, and the spermatogenesis index was significantly reduced in both exposed groups. Sperm concentration was significantly reduced in both exposed groups, sperm motility decreased significantly in the 4-hour group, and sperm viability increased substantially in the 24-hour group.

Researchers exposed pregnant rats to WiFi-frequency radiation (2.45 GHz) throughout pregnancy, then examined their offspring's thyroid glands one year after birth. The study found significant thyroid damage including increased cell death, DNA breaks, tissue scarring, and abnormal cells in the exposed offspring. This suggests prenatal WiFi exposure may cause lasting thyroid problems that persist into adulthood.

Researchers exposed several human and rodent cell types to 60 Hz ELF-MF at 10 and 16 mT for 72 hours. All cell types showed an approximately 20% or greater increase in proliferation at 14 mT compared with sham exposure, with no further increase at 16 mT. The proliferation increase was accompanied by activation of the MEK-ERK pathway and NF-κB, but not Akt, and a slight increase in S phase population, while ROS and calcium levels remained unchanged.

Twenty-four Wistar albino male rats were divided into sham, EMF, PTZ, and EMF+PTZ groups and exposed to alternating 50-Hz and 5-mT EMF for 165 min a day for 7 days while epileptic seizures were induced with PTZ. A statistically significant difference was observed in learning and short-term memory between the EMF+PTZ group and the PTZ group. Analgesia latency statistically significantly increased in the ELF-EMF and ELF-EMF+PTZ groups compared with both the control and epilepsy groups. TOS increased in the prefrontal cortex of the PTZ group versus sham, increased in the hippocampus of both PTZ and ELF-EMF+PTZ groups versus sham, and ELF-EMF decreased the hippocampal TOS increase in the PTZ group.

Researchers exposed various human and animal cells to 60 Hz magnetic fields at industrial-strength levels (10-16 mT) for 72 hours. They found that 14 mT exposure increased cell multiplication by at least 20% across all cell types tested, including cancer cells, by activating specific cellular growth pathways. The effect occurred without changes in cellular stress markers or calcium levels.

K. xylinus cells were subjected to a rotating magnetic field at frequencies of 5 and 50 Hz for durations ranging from 12 to 72 h. Gene expression was assessed using quantitative polymerase chain reaction. RMF exposure significantly enhanced BC production efficiency, with average wet and dry BC yields increasing by 28% and 18% and upregulated bcs gene expression showing statistically significant changes at both frequencies and all time points, the strongest effects at 5 Hz.

Researchers exposed rats to 50 Hz electromagnetic fields (like those from power lines) for 7 days and found the EMF actually improved learning and memory in epileptic animals while reducing brain oxidative stress. The study suggests power line frequency EMF may have protective effects on brain function under certain conditions.

Researchers randomly assigned 7-8-week-old male C57BL/6 mice to a sham group or a 4.9 GHz RFR group (16 mice per group) and assessed anxiety, depression, cognition, sperm quality, and fertility in their male offspring. Paternal RFR exposure induced anxiety-like behaviors and impaired sperm quality in the first-generation male offspring. No significant effects were observed on depression-like behaviors, cognitive performance, or fertility across F1-F2 generations.
