Flora and fauna: how nonhuman species interact with natural and man-made EMF at ecosystem levels and public policy recommendations

Research PubMed: RF-EMF health Dec 8, 2025

This PubMed-listed article argues that ambient nonionizing EMF exposures (especially RF-EMF) have increased substantially over the past 60 years and are now pervasive, including from terrestrial networks and low-earth-orbit satellites. It claims these chronic, low-intensity exposures are biologically active and may…

Mechanism first explanation of how the plasma membrane potential controls immune responses

Independent Voices RF Safe Nov 4, 2025

An RF Safe article argues that plasma membrane potential (Vm) is a key control variable for immune cell behavior by shaping ion driving forces, especially Ca2+ influx through CRAC channels and K+ channel–mediated hyperpolarization. It describes proposed links between Vm-regulated ion flux and downstream immune…

Female Crabs Are More Sensitive to Environmentally Relevant Electromagnetic Fields from Submarine Power Cables

Low-Frequency Electromagnetic Fields Enhance the Directional Migration of Mesenchymal Stem Cells.

Research RF Safe Research Library Jan 1, 2025

This in vitro study examined whether low-frequency electromagnetic fields (EMF) affect mesenchymal stem cell (MSC) polarity and directional migration at wound edges. EMF-treated cells showed increased asymmetric redistribution of the polarity marker β-COP and altered γ-tubulin localization at wound margins. The…

Microglial Response to Inflammatory Stimuli Under Electromagnetic Field Exposure.

Research RF Safe Research Library Jan 1, 2025

This in vitro study examined whether extremely low frequency EMF exposure alters responses of TNF-α-stimulated human microglial cells (HMC3). Cells exposed to 2.5 or 5 Hz EMF for 3 minutes showed increased survival under high TNF-α conditions and reduced migration compared with TNF-α treatment alone. EMF also…

Sinusoidal Extremely Low-Frequency Electromagnetic Stimulation (ELF-EMS) Promotes Angiogenesis In Vitro.

Research RF Safe Research Library Jan 1, 2025

This in vitro/in ovo study examined whether extremely low-frequency electromagnetic stimulation (ELF-EMS; 13.5 mT at 10 and 60 Hz) activates angiogenic processes under homeostatic conditions. In human microvascular endothelial cells, ELF-EMS increased proliferation, migration/transmigration, and tube formation, with…

Effect of Electromagnetic Field on Proliferation and Migration of Fibroblasts and Keratinocytes: Implications in Wound Healing and Regeneration.

Research RF Safe Research Library Jan 1, 2024

This narrative review discusses reported effects of EMF, including low-frequency EMF (LF-EMF), on cell behaviors relevant to wound healing and on recovery processes after traumatic brain injury (TBI). It summarizes literature suggesting EMF can promote migration and proliferation of fibroblasts, keratinocytes, and…

Electromagnetic field as a possible inhibitor of tumor invasion by declining E-cadherin/N-cadherin switching in triple negative breast cancer.

Research RF Safe Research Library Jan 1, 2024

This in vitro study exposed breast cell lines to a 1 Hz, 100 mT ELF-EMF for 5 days (2 h/day) and assessed migration, invasion, and cadherin expression. The authors report reduced migration and invasion in MDA-MB231 cells versus sham exposure. They also report increased E-cadherin and decreased N-cadherin in MDA-MB231…

Transcriptomic Analysis of Gene Expression and Effect of Electromagnetic Field in Brain Tissue after Traumatic Brain Injury.
