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 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.

EMR exposure caused marked structural damage to seminiferous tubules, increased collagen deposition, expanded tubular and interstitial volumes, raised IL-6 and TNF-α expression, and reduced antioxidant enzyme activities while increasing MDA levels. Alpha-lipoic acid supplementation prevented the structural damage, lowered inflammatory markers, restored AR, ZO-1, and ZO-2 expression, and reversed the oxidative stress parameters.

The researchers indirectly analyzed the relationship between oxidative-stress-responsive genes after Wi-Fi 2.4 GHz exposure and genes linked to Alzheimer’s disease. They reported that prolonged exposure to this radiation could worsen the modification of key neurodegeneration genes such as GSK3B and APOE. The authors note that the link between wireless systems and Alzheimer’s disease remains inconclusive and requires further research.

Researchers investigated the effects of 4.9 GHz radiofrequency field on emotional behaviors and spatial memory in adult male mice. They used open field test, tail suspension test, and Y maze to assess anxiety, depression-like behavior, and spatial memory. Anxiety-like behavior and spatial memory did not change after exposure, but depression-like behavior was induced. Neuron number decreased and pyroptosis increased in the amygdala but not the hippocampus.

Researchers created two groups of seven rats each, one sham control and one exposed to 2100 MHz RF-EMF for five hours per day over 14 days. Brain tissue from exposed rats showed vascular alterations and significant edema. The exposed group had 18.26% tail DNA compared to 4.06% in controls, indicating more cellular damage. Testicular tissue showed significant deterioration of spermatogenic cells. Bax and bcl-2 gene expression changed significantly, while p53 did not.

Researchers exposed zebrafish embryos to unmodulated 700 MHz and 3500 MHz radiofrequency radiation for 1 and 4 hours during the blastula period and assessed outcomes up to 120 hours post fertilization. The exposure did not affect mortality, hatching, or body length, but caused specific organ morphological changes and lasting behavioral alterations in activity, anxiety-like behavior, and habituation. Effects were stronger at 700 MHz, particularly after 4 hours of exposure, and acetylcholinesterase activity was reduced.
