Researchers studied how ultrashort electric pulses affect neuroblastoma cells, focusing on extremely low energy levels that had never been tested before. They found that even these minimal electric exposures could cause changes in gene activity within the cells. The findings suggest that medical devices using electric pulses may be safer than previously thought, while also opening doors for new therapeutic applications.

This study compared how extremely low-frequency magnetic fields (ELF-MF) and alternating current (AC) stimulations affect human vestibular system function by measuring changes in subjective visual vertical (SVV) perception. The researchers found that while both stimulation types produced similar SVV precision levels, ELF-MF stimulation required longer adjustment times and showed higher variability compared to AC stimulation, with differences between the two modalities being relatively small.

Scientists exposed juvenile thornback rays to magnetic fields similar to those from underwater power cables, testing both direct current and 50 Hz alternating current at 450 microTesla strength. The rays showed increased activity during midday under direct current exposure and synchronized behaviors under alternating current exposure. This research helps understand how marine renewable energy infrastructure might affect magneto-sensitive marine species like sharks and rays.

Researchers exposed pregnant rats and their offspring to electromagnetic fields from pregnancy through 42 days after birth, testing behavior and brain proteins. EMF exposure increased anxiety and reduced activity in the young rats, while decreasing important brain proteins needed for proper nerve connections. Zinc supplements helped female offspring somewhat but had no effect on males.

This study examined how directed current electric fields affect mouse melanoma B16-F10 cells, using RNA sequencing to analyze transcriptional changes. The cells migrated toward the cathode in a voltage-dependent manner, with approximately 3000 upregulated and 2613 downregulated genes identified, including genes associated with cell migration, tumorigenesis, invasion, and metastasis.

Researchers exposed mice to a hypomagnetic field (HMF), an environment with dramatically reduced magnetic field strength compared to Earth's natural geomagnetic field, for eight weeks. The HMF-exposed mice showed significant cognitive impairments and elevated reactive oxygen species (ROS) in their hippocampus, the brain region responsible for memory and navigation. This study reveals that Earth's natural magnetic field plays a crucial role in maintaining proper brain chemistry and cognitive function.

Polish researchers exposed human immune cells to 7 Hz magnetic fields (30 mT) for 3 hours and found significant changes in protein expression during phagocytosis, the process by which immune cells engulf foreign particles. The electromagnetic field exposure particularly affected iNOS protein levels and related genes involved in immune response pathways.

This 2022 review examined how pulsed electromagnetic fields and physical stimulation can induce neurodifferentiation of human bone marrow-derived mesenchymal stem cells (hBM-MSCs) through activation of the ERK/CREB signaling pathway. The study focused on how these mechanisms promote neurogenesis in models of cerebral ischemia.

Researchers exposed pregnant and nursing rats to extremely low frequency electromagnetic fields (ELF-EMF) and studied immune system effects in their offspring. Female offspring showed increased inflammatory markers and immune cell changes, while males were less affected. This suggests EMF exposure during critical developmental periods may program long-term immune dysfunction in a gender-specific way.

This 2022 in vitro study examined whether 50 and 60 Hz magnetic fields (at 100 µTRMS) affected oxidative stress, DNA damage, and related gene expression in human neuroblastoma cells. The researchers found only weak effects, including suggestive evidence of increased ROS-related gene expression and decreased menadione-induced ROS levels with 50 Hz exposure, while DNA damage and repair rates were unaffected.

Researchers tested extremely low frequency electromagnetic fields (ELF-EMF) and silver nanoparticles against bacteria and breast cancer cells. The combination achieved 100% bacterial kill rates and triggered cancer cell death through programmed cell destruction. The study suggests these agents work by creating oxidative stress that damages harmful cells while potentially sparing healthy ones.

Spanish researchers exposed human neuroblastoma cells to 50 Hz magnetic fields at 100 microtesla (the frequency and intensity of European electrical systems) for 30 to 120 minutes. The exposure altered expression and distribution of p53, a critical protein that regulates cell growth and prevents cancer, while also increasing levels of an antiapoptotic protein. These cellular changes suggest that everyday power frequency fields may interfere with the body's natural tumor suppression mechanisms.

This suggests certain EMF exposures might have therapeutic potential against gastric cancer.
