Inhibition of mitochondrial NADH:ubiquinone oxidoreductase by spinning oscillating magnetic fields causes toxicity in cancer cells
This in vitro study examines a spinning oscillating magnetic field (sOMF) generated by an Oncomagnetic device and reports selective toxicity in glioma cancer cells. The abstract attributes effects to ROS-dependent inhibition of mitochondrial complex I, with downstream oxidative stress, DNA damage, cell-cycle arrest, and apoptosis. It also reports no similar toxic effects in normal human astrocytes/astroglial cells under the studied conditions.
Female Crabs Are More Sensitive to Environmentally Relevant Electromagnetic Fields from Submarine Power Cables
This controlled laboratory study examined sex-specific behavioral responses of juvenile shore crabs to magnetic fields intended to represent submarine power cable EMFs. Females showed consistent attraction to EMF-exposed zones across 500–3,200 μT exposures, whereas males showed no consistent spatial preference. The authors suggest such sex-specific sensitivity could disrupt female-driven behaviors relevant to migration and reproduction, with potential ecological implications.
Analyzing the Impact of Occupational Exposures on Male Fertility Indicators: A Machine Learning Approach
This occupational epidemiology study used machine learning to evaluate whether workplace exposures (including magnetic and electric fields, vibration, noise, and heat stress) predict male reproductive indicators in 80 workers. The models and explainable AI outputs highlighted magnetic and electric field exposures and age as key predictors linked to lower free testosterone. The authors also report a 10-year forecast identifying electric field exposure as the most important long-term risk factor.
Electromagnetic wireless remote control of mammalian transgene expression
This animal proof-of-concept study describes an engineered nanoparticle–cell interface (EMPOWER) enabling wireless regulation of transgene expression using a 1-kHz magnetic field. Chitosan-coated multiferroic nanoparticles reportedly generate intracellular ROS that activates KEAP1/NRF2 biosensors connected to ROS-responsive promoters. In a mouse model of type 1 diabetes, implanted engineered cells expressing an EMPOWER-controlled insulin system reportedly normalized blood glucose in response to a weak magnetic field.
