Researchers exposed bone marrow stem cells to 75 Hz electromagnetic fields at 400 µT strength, then injected them into rats with Parkinson's disease. The EMF-treated stem cells showed better differentiation into neurons and improved the rats' motor function compared to untreated cells. This suggests specific EMF frequencies might enhance stem cell therapy for neurodegenerative diseases.

Researchers exposed mice to a 50 Hz electric field at 10 kV/m and found it consistently reduced stress hormone levels (glucocorticoids) caused by repeated immobilization stress. The stress-reducing effect worked regardless of how many times mice experienced stress or which way the electrodes were oriented, and appeared strongest when the head remained exposed to the field. This suggests extremely low frequency electric fields may have reproducible biological effects on stress response systems.

Researchers exposed laboratory animals to 500 μT electromagnetic fields at 50 Hz (power line frequency) and used advanced spectroscopy to detect molecular changes in brain and liver tissue. The study found increased oxidative damage, reduced antioxidant defenses, and structural changes to proteins and lipids in exposed animals. This provides direct evidence that power line frequency EMF causes measurable biochemical harm at the cellular level.

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.

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.

Researchers exposed male rats to extremely low-frequency magnetic fields (ELF-MF) for short periods and found the animals became less active and showed signs of sleepiness. The rats moved around less in behavioral tests, and their oxalate acid levels decreased, suggesting the magnetic fields may have a sedating effect.

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.

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.

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.

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.
