Researchers tested whether extremely low frequency electromagnetic fields (ELF-EMFs) affect brain learning and memory by comparing EMF exposure to direct electrical current in rat brain tissue. Both EMF exposure and tiny electrical currents reduced long-term potentiation (LTP), a key process for learning and memory formation. The study suggests EMF effects aren't solely due to the electrical currents they induce in brain tissue.

Researchers studied how pulsed electromagnetic fields (75 Hz, 1.5 mT) work with bone growth protein BMP2 to help human stem cells develop into bone cells. They found the electromagnetic fields enhanced the protein's bone-building effects by activating specific cellular pathways. This helps explain why doctors successfully use electromagnetic therapy to heal bone fractures.

Researchers tested whether magnetic fields could enhance the effectiveness of brain cancer treatment.

Researchers exposed honeybees to 50 Hz electromagnetic fields (the same frequency as power lines) at various durations and analyzed their body chemistry using infrared spectroscopy. They found that EMF exposure longer than 2 hours caused measurable changes to the bees' DNA, RNA, proteins, and cell membranes.

Researchers exposed human neuronal cells and plant roots to magnetic fields ranging from very weak (1 mT) to extremely strong (0.8 T) at 50 Hz and static frequencies. They found that even the weakest magnetic fields caused DNA to uncoil and chromosomes to physically align with the magnetic field direction. This demonstrates that magnetic fields can reorganize genetic material at intensities far below what most safety standards consider harmful.

Researchers exposed rainbow trout eggs and larvae to magnetic fields similar to those from underwater power cables for 36 days. While the electromagnetic fields didn't affect survival or growth, they did speed up how quickly the fish absorbed their yolk sacs, which could impact their ability to feed effectively after hatching.

Researchers exposed rainbow trout larvae, marine clams, and ragworms to 50 Hz electromagnetic fields at 1 milliTesla strength for up to 40 days. All three species showed DNA damage and cellular abnormalities, with clams experiencing the most severe effects across six different measures of genetic and cellular harm. This is the first study to demonstrate that power-line frequency EMF can damage aquatic life at the cellular level.

This study examined 933 Iranian women and found that those living within 500 meters of high-voltage power lines were over 4 times more likely to experience infertility compared to women living farther away. Even women living 500-1000 meters from power lines showed increased infertility risk. The researchers concluded that current safety guidelines for electromagnetic field exposure may be inadequate.

Researchers exposed rats to 50 Hz magnetic fields (the same frequency as power lines) for 2 hours daily over 15 days and found the fields produced pain relief (analgesia).

The study shows that extremely low frequency magnetic fields can directly alter brain chemistry and pain perception.
