Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito

Research PubMed: RF-EMF health Dec 25, 2025

A PubMed-listed study examined whether exposure to 5G New Radio (5G-NR) radiofrequency electromagnetic fields (RF-EMF) at 3.6 GHz affects larval development in Aedes aegypti mosquitoes. Using a custom reverberation-chamber exposure setup and numerical simulations to estimate dose, the authors report slower development at a lower exposure level (46.2 V/m), particularly in nutritionally weakened larvae. At a higher exposure level (182.6 V/m), the study reports dielectric heating that altered development timing and adult size.

Exposure to 5G-NR electromagnetic fields affects larval development of Aedes aegypti mosquito

Research RF Safe Research Library Jan 1, 2025

This animal study exposed Aedes aegypti larvae to 5G-NR RF-EMF at 3.6 GHz for 5 days under two feeding regimes. The study reports delayed development at a lower exposure level mainly in nutritionally weakened larvae, and at a higher exposure level reports developmental changes and reduced adult size attributed to dielectric heating. Mortality and wing length asymmetry were reported as unchanged, and the authors note such high exposure levels are unlikely in natural aquatic settings.

NTP Lite: The Japan-Korea Collaborative RF Exposure Toxicity Project [Health Matters]

Research RF Safe Research Library Jan 1, 2025

This magazine article reviews the Japan-Korea "NTP Lite" RF animal toxicity collaboration and its relationship to prior NTP (2018) and Ramazzini Institute reports of RF-associated tumors in male rats. It notes NTP Lite used a single whole-body SAR of 4 W/kg and completed a two-year exposure phase in 2022, but final reporting is delayed with histopathology and genotoxicity work ongoing. The author highlights protocol harmonization across labs while raising concerns about unexplained animal deaths and physiological differences in exposed groups, and frames the broader evidence as supportive of RF-related cancer risk in laboratory animals.

Simultaneous 4G and 5G EMF Exposure and Field Uniformity in a Reverberation Chamber for Animal Studies

Research RF Safe Research Library Jan 1, 2025

This engineering study describes the design and validation of a reverberation chamber intended for large-scale animal carcinogenicity research with RF EMF relevant to 4G/5G. E-field uniformity was tested under four loading scenarios, including setups with 80 Sprague-Dawley rats. The chamber achieved better than 1.36 dB E-field uniformity across scenarios, and the authors report a method to predict composite E-field intensity for simultaneous multi-frequency exposures.

Exposure to 26.5 GHz, 5G modulated and unmodulated signal, does not affect key cellular endpoints of human neuroblastoma cells

Research RF Safe Research Library Jan 1, 2025

This in vitro study examined whether 26.5 GHz millimeter-wave exposure (continuous wave and 5G-modulated) affects key cellular endpoints in human neuroblastoma cells. Cells were exposed for 3 hours at SAR 1.25 W/kg using a reverberation-chamber system, with assessments including cell cycle and DNA damage. The study reports no effects from exposure alone or when combined with the oxidant menadione, while noting that additional studies across varied conditions are needed.

Characterization of the Core Temperature Response of Free-Moving Rats to 1.95 GHz Electromagnetic Fields

Research RF Safe Research Library Jan 1, 2025

This animal study measured core body temperature in free-moving male and female Sprague Dawley rats during and after 3-hour exposure to 1.95 GHz RF-EMF at multiple whole-body average SAR levels. A measurable thermal response was reported at 4 W/kg, while lower SAR conditions showed smaller or no significant temperature increases. The authors note that temperature dropped quickly after exposure ended, implying post-exposure measurements may underestimate peak heating.

The CB1R of mPFC is involved in anxiety-like behavior induced by 0.8/2.65 GHz dual-frequency electromagnetic radiation

Research RF Safe Research Library Jan 1, 2025

This animal study reports that dual-frequency RF EMR exposure (0.8/2.65 GHz, 4 W/kg) induced anxiety-like behavior in mice. It also reports reduced CB1R and endocannabinoid levels in the mPFC and altered endocannabinoid system markers in the BLA. CB1R overexpression or knockdown in the mPFC reportedly decreased or increased anxiety-like behavior, respectively, suggesting a mechanistic link in this model.
