This biophysics study used molecular dynamics simulations to examine how terahertz electromagnetic fields affect ion permeation in voltage-gated potassium (Kv1.2) and sodium (Nav1.5) channels. The simulations report increased ion permeability at several specific terahertz frequencies, with effects depending on field frequency and direction and increasing with field amplitude. The authors frame these results as evidence of specific EMF–ion channel interactions with potential health relevance and possible biomedical applications.

This in vitro study examined effects of moderate static magnetic field exposure on sympathetic neuron-like PC12 cells. The authors report a significant reduction in voltage-gated potassium (Kv) channel current density after 18 hours of exposure, with the reduction persisting after the field was removed. RNA sequencing identified 37 SMF-sensitive genes and pathway analyses suggested upregulation of signaling associated with reduced neuronal excitability.
