3.5-GHz radiofrequency electromagnetic radiation promotes the development of Drosophila melanogaster

Unknown authors · 2022

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.

Gupta V, Srivastava R. 2.45 GHz microwave radiation induced oxidative stress: Role of inflammatory cytokines in regulating male fertility through estrogen receptor alpha in Gallus gallus domesticus

Unknown authors · 2022

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.

Gupta V, Srivastava R. 2.45 GHz microwave radiation induced oxidative stress: Role of inflammatory cytokines in regulating male fertility through estrogen receptor alpha in Gallus gallus domesticus

Unknown authors · 2022

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.

Unknown authors · 2022

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.

Changes in the excitability of primary hippocampal neurons following exposure to 3.0 GHz radiofrequency electromagnetic fields

Unknown authors · 2022

The study investigated changes in neuronal activity and synaptic transmission after a 60-minute exposure to 3.0 GHz RF-EMF at a low dose (SAR < 1 W/kg). RF-EMF exposure decreased the amplitude of action potentials, depolarized resting membrane potential, and increased neuronal excitability and synaptic transmission in cultured primary hippocampal neurons.

Transcriptomic and Long-Term Behavioral Deficits Associated with Developmental 3.5 GHz Radiofrequency Radiation Exposures in Zebrafish

Unknown authors · 2022

Researchers exposed developing zebrafish to 3.5 GHz radiofrequency radiation (used in 5G networks) and found subtle but persistent behavioral abnormalities that lasted into adulthood. The study also revealed disrupted gene expression affecting metabolism pathways. This suggests 5G frequencies may impact developing nervous systems in ways that persist long-term.

Unknown authors · 2022

Researchers exposed fruit flies to 2.4 GHz WiFi radiation at non-thermal levels and found it caused DNA damage, increased oxidative stress, behavioral changes, and accelerated tumor growth. The study demonstrated that WiFi signals triggered genetic instability by disrupting normal chromosome structure and silencing mechanisms in both brain and reproductive tissues. These findings suggest WiFi radiation may have biological effects beyond heating that warrant further investigation in humans.

2.4 GHz Electromagnetic Field Influences the Response of the Circadian Oscillator in the Colorectal Cancer Cell Line DLD1 to miR-34a- Mediated Regulation

Unknown authors · 2022

Researchers exposed miR-34a-transfected DLD1 colorectal cancer cells to 2.4 GHz RF-EMF for 24 hours and evaluated effects using real-time PCR, scratch assay, and MTS test. Administration of miR-34a decreased expression of per2, bmal1, sirtuin1, and survivin and inhibited proliferation and migration of DLD1 cells. RF-EMF exposure increased cry1 mRNA expression, weakened miR-34a's inhibition of per2, abolished its inhibition of survivin, and eliminated miR-34a's effects on proliferation and migration. The authors concluded that RF-EMF strongly influenced miR-34a-mediated regulation of the peripheral circadian oscillator in DLD1 cells.

Changes in the histopathology and in the proteins related to the MAPK pathway in the brains of rats exposed to pre and postnatal radiofrequency radiation over four generations

Tan B, Tan FC, Yalcin B, Dasdag S, Yegin K, Yay AH · 2022

The study created four groups (sham, irradiated female, irradiated male, and irradiated male and female) with one male and three females each. The irradiated groups were whole-body exposed to 2450 MHz continuous wave radiofrequency radiation for 12 hours per day across four generations. The researchers examined fetal brain development, histopathological changes in female rats, and hippocampal MAPK protein levels in male rats. In exposed groups, hemorrhagic areas, irregular cellular localization, and vascular structures were observed in the brains of fetal and adult female rats across all generations. In adult male rats, phosphorylated ERK, tau, JNK, and p38 were significantly increased in the brain across all generations.

Changes in the histopathology and in the proteins related to the MAPK pathway in the brains of rats exposed to pre and postnatal radiofrequency radiation over four generations

Tan B, Tan FC, Yalcin B, Dasdag S, Yegin K, Yay AH · 2022

Turkish researchers exposed rats to WiFi-frequency radiation (2450 MHz) for 12 hours daily across four generations, starting before conception. They found brain hemorrhaging and irregular cell patterns in fetuses and adult females, plus elevated stress proteins linked to memory problems in males. The effects persisted and potentially worsened across generations.

Lost opportunities for cancer prevention: historical evidence on early warnings with emphasis on radiofrequency radiation

Hardell & Carlberg · 2021

The paper discusses historical lessons from early warnings on cancer risks and lost prevention opportunities. It states that radiofrequency radiation has a cancer-causing effect and that decades of studies show increased human cancer risk. Based on three case-control studies of wireless phone use, the authors present a preventable fraction for brain tumors and note an increase in undefined brain tumors in Sweden, especially among ages 20–39, which they suggest may be linked to high wireless phone use among young people.

Effects of 2.45 GHz Wi-Fi exposure on sleep-dependent memory consolidation

Unknown authors · 2021

Thirty young men participated in a double-blind, sham-controlled crossover study with all-night 2.45 GHz Wi-Fi exposure. Declarative memory improved overnight with Wi-Fi exposure, but emotional and procedural memory were unaffected. No sleep-specific physiological parameters changed with exposure, so the behavioral effect lacked physiological support and may be a random finding.

Analysis of thiol/disulphide homeostasis and oxidant-antioxidant status as a result of exposure to radio-frequency electromagnetic fields

Yavaş MC, Yegin K, Oruç S, Delen K, Sirav B · 2021

Fourteen male Sprague Dawley rats were divided into a sham-control group and a 2100 MHz exposed group. The exposed rats received GSM-like signals for 5 h/day, 7 days per week for 14 days. Serum total thiol, native thiol, and disulphide levels were higher in the exposed group with p values of 0,219 for total thiol, 0,416 for native thiol and 0,566 for disulphide. Total antioxidant status, total oxidant status, and oxidative stress index were also higher in the exposed group. The researchers concluded that RF-EMFs did not cause oxidative stress and statistically changes in thiol/disulphide homeostasis.

Potential influence of prenatal 2.45 GHz radiofrequency electromagnetic field exposure on Wistar albino rat testis

Unknown authors · 2021

Pregnant Wistar albino rats were exposed to pulsed 2.45 GHz microwave radiation at 2.8 mW/cm² for 2 hours daily throughout pregnancy. Male offspring were not exposed after birth and were examined at 75 days of age. Exposed adult rats showed irregular seminiferous tubules, degenerated germ cells, reduced tubule diameter and epithelial height, and increased interstitial space. Exposed rats also had more vacuoles, altered organelles, necrotizing cells, empty spaces between Sertoli and germ cells, and increased lipid droplets in Leydig cells. Fluoro Jade-C and superoxide dismutase 2 positivity were increased in exposed rats.

Testing of behavioral and cognitive development in rats after prenatal exposure to 1800 and 2400 MHz radiofrequency fields

Unknown authors · 2020

Pregnant rats were exposed to radiofrequency fields starting on day 21 of pregnancy, and offspring were tested with Y maze at 3 weeks, open field at 7 weeks, and hippocampal NMDAR expression at 9 weeks. The 1800 MHz and 1800 MHz + WiFi groups showed a downward trend in body weight, and the WiFi group opened eyes earlier than controls. In open field tests, the 1800 MHz + WiFi group had shorter overall path length and delayed stationary time, the WiFi group had shorter path length and increased velocity in the error arm, and the 1800 MHz + WiFi group showed increased central area activity. Both exposure groups down-regulated NR2A and NR2B and up-regulated NR2D, NR3A, and NR3B, while the WiFi group also up-regulated NR1 and NR2C.
