Researchers exposed bone cancer cells to extremely low frequency electromagnetic fields (ELF-EMF) at 50 Hz and 1 milliTesla for up to 3 hours. They found the EMF exposure triggered cancer cell death (apoptosis) by increasing oxidative stress and activating specific cellular pathways. This suggests ELF-EMF might have potential therapeutic applications against bone cancer, though this was only tested in laboratory cell cultures, not living organisms.

Researchers exposed human lung cells to 60 Hz magnetic fields (1-2 mT) alone and combined with radiation or hydrogen peroxide to test whether EMFs might make cells more vulnerable to genetic damage. The magnetic fields alone caused no genetic damage, and they didn't make the cells more susceptible to damage when combined with other stressors. This suggests that power frequency magnetic fields at these levels don't compromise cellular genetic stability.

Researchers exposed mouse reproductive cells to electromagnetic fields from power lines and cell phones to compare DNA damage. Both types caused genetic damage through different mechanisms - power line fields broke DNA strands while cell phone radiation caused oxidative damage to DNA bases.

Researchers exposed mouse sperm cells to two types of electromagnetic fields - 50 Hz extremely low frequency (like power lines) and 1800 MHz radiofrequency (like cell phones) - to compare DNA damage. They found that high-intensity ELF fields caused DNA strand breaks, while high-intensity RF fields caused oxidative DNA damage through different mechanisms. The study suggests both types of EMF can damage DNA at high exposure levels, but through distinct biological pathways.

Italian researchers exposed human brain cells to power line frequency magnetic fields (50 Hz) while simultaneously stressing them with hydrogen peroxide. Over 72 hours, the magnetic field exposure did not increase DNA damage beyond what the chemical stress alone caused, suggesting power-frequency fields may not worsen cellular damage.

Researchers exposed mice to 50 Hz magnetic fields (the same frequency as household electricity) for up to 120 days and measured anxiety-like behaviors. The magnetic field exposure significantly increased anxiety in the animals, and the researchers identified that this effect occurred through changes in NMDA receptors in the brain. The study provides biological evidence that long-term exposure to extremely low frequency magnetic fields can alter brain chemistry and behavior.

Researchers exposed nerve cells to 50 Hz magnetic fields (power line frequency) for five days. The magnetic fields enhanced nerve cell growth, increasing nerve extensions and proteins needed for nerve development. This suggests power line frequencies might stimulate nerve regeneration and offer insights for treating neurodegenerative diseases.

Researchers exposed mice to 50 Hz magnetic fields (power line frequency) for 8 hours daily and found it caused obsessive-compulsive behaviors. The exposure increased nitric oxide in brain regions controlling behavior, suggesting this chemical pathway explains how magnetic fields can affect mental health.

Researchers exposed pregnant mice and their newborn pups to 50 Hz magnetic fields (the same frequency as household electrical systems) during critical developmental periods. The exposed male mice later showed autism-like behaviors, including reduced social interaction and less interest in exploring new social situations, while their movement, coordination, and other basic functions remained normal. This suggests that magnetic field exposure during early brain development might contribute to autism spectrum disorders.

Researchers exposed human brain cells to 50 Hz electromagnetic fields (the type from power lines) for up to 24 hours and found the cells produced more harmful molecules called free radicals and nitric oxide. While the cells initially tried to defend themselves by boosting antioxidant activity, this protection failed when the cells faced additional stress, leading to cellular damage that could contribute to brain diseases like Alzheimer's.

Dutch researchers exposed nerve cells (PC12 cells) to 50 Hz magnetic fields at levels up to 1,000 microtesla for periods ranging from 30 minutes to 48 hours. They found no effects on calcium levels, oxidative stress, or cell membrane integrity, even in cells that had been chemically stressed to make them more vulnerable. The exposure levels were 10,000 times higher than typical background magnetic field exposure.

Researchers exposed nerve cells (PC12 cells) to 50 Hz magnetic fields at extremely high levels - up to 1000 microteslas, which is 10,000 times stronger than typical background exposure. They tested both healthy cells and chemically-stressed cells that were more vulnerable to damage. The study found no toxic effects on the nerve cells' calcium balance, oxidative stress levels, or cell membrane integrity, even at these extraordinarily high exposure levels.

Researchers exposed four different types of human and mouse cells to 60 Hz magnetic fields (the same frequency as power lines) for 4 to 16 hours, both alone and combined with known DNA-damaging agents like radiation and hydrogen peroxide. They found no DNA damage from the magnetic field exposure alone, and the magnetic fields did not make other DNA-damaging agents more harmful. This suggests that power-frequency magnetic fields at 1 milliTesla may not directly damage cellular DNA.

Researchers tested cognitive and brain function in 310 Chinese electrical workers regularly exposed to power line electromagnetic fields during equipment inspections, comparing them to 300 unexposed office workers. The study found no differences in memory, reaction time, or other brain performance measures between the two groups. This suggests that occupational exposure to power frequency electromagnetic fields may not impair basic cognitive abilities.

Researchers exposed human bone marrow stem cells to 50 Hz magnetic fields (the same frequency as power lines) at 1 milliTesla for several days. They found that this EMF exposure triggered the stem cells to transform into nerve cells by activating specific cellular pathways and generating reactive oxygen species (ROS). This suggests that power-frequency magnetic fields can directly influence how our stem cells develop and differentiate.
