Researchers exposed mice to 1,950 MHz radiofrequency radiation (similar to cell phone frequencies) for an extended period and observed changes in both behavior and gene expression patterns. The study found measurable alterations in how genes were expressed in the brain, along with behavioral modifications in the exposed animals. This adds to growing evidence that chronic RF exposure may affect nervous system function at the cellular level.

Researchers reviewed existing studies on whether electromagnetic radiation from wireless technologies (4G, 5G) and artificial light at night threaten pollinators like bees. They found very limited high-quality research, with only scattered evidence that some EMR affects pollinator behavior or communities. The science remains largely inconclusive about whether these technologies pose significant risks to the insects that pollinate our food crops.
The effect of Wi-Fi electromagnetic waves on neuronal response properties in rat barrel cortexSistani S et al. · 2019
Researchers exposed rats to Wi-Fi radiation at 2.4 GHz for one hour and measured how brain neurons in the barrel cortex responded to whisker stimulation. While basic neural activity remained unchanged, the study found that Wi-Fi exposure altered how neurons integrated information from multiple whisker inputs. This suggests Wi-Fi radiation can subtly modify brain processing even when individual neural responses appear normal.

This comprehensive review examined decades of research on radio-frequency radiation (RFR) from cell phones and towers, finding evidence of cancer, DNA damage, and reproductive harm. The authors analyzed studies showing children's developing brains absorb up to 10 times more radiation than adults, and men carrying phones in pockets have significantly damaged sperm. They recommend governments warn the public that keeping phones next to the body is harmful.

Researchers tested whether low-field magnetic stimulation (LFMS) could help brain-injured mice recover from repeated concussions. Mice that received daily 20-minute LFMS treatments showed significantly improved memory, movement, and brain health compared to untreated injured mice. The therapy appeared to work by restoring protective brain proteins and reducing inflammation.

Researchers exposed human neural stem cells to extremely low frequency magnetic fields and found they developed into mature neurons more efficiently. The study discovered this happens through activation of NMDA receptors, brain channels that control calcium flow. This suggests magnetic fields might stimulate brain cell development through specific biological pathways.

Researchers tested whether the static magnetic field (350 μT) from electric vehicles affects driving performance and brain function in 17 student volunteers. They found no significant impact on driving ability or cognitive functions, though they detected a correlation between specific brain wave patterns and reaction times.
Goraghani MS et al. · 2019
Researchers gave young rats a low dose of MK-801 (a brain receptor blocker) and exposed them to static magnetic fields during critical brain development. While MK-801 alone caused no lasting problems, combining it with magnetic field exposure led to significant learning, memory, and behavioral issues in adult rats. This suggests magnetic fields can amplify the harmful effects of certain brain chemicals.
Yao F et al. · 2019
Researchers exposed brain cells that create myelin (the protective coating around nerve fibers) to low-frequency pulsed electromagnetic fields. The electromagnetic fields helped these cells mature and produce more myelin, which could potentially aid recovery from spinal cord injuries. The study found this happened through specific genetic mechanisms involving microRNAs.
Cichon N et al. · 2019
Researchers studied stroke patients receiving extremely low frequency electromagnetic field treatment alongside standard physical therapy. They found that EMF exposure increased levels of certain inflammatory molecules in the blood, particularly IL-1β and IL-2. The authors suggest these changes might actually help protect brain cells during recovery.

Researchers exposed pregnant mice and their offspring to LTE cell phone signals (1,846 MHz) during critical early development periods. The study found that this early-life exposure caused lasting behavioral changes that persisted into adulthood, with different effects depending on radiation intensity. This suggests that exposure to cell phone radiation during pregnancy and early childhood may have permanent consequences for behavior and brain function.

Turkish researchers exposed rats to 900 MHz cell phone radiation for one hour daily over 28 days and found significant damage to spinal cord motor neurons. The study also tested whether thymoquinone, a natural antioxidant compound, could protect against this damage and found it successfully prevented the neurological harm. This suggests cell phone radiation may affect the nervous system beyond just the brain.

Researchers exposed human and rat brain cells (astrocytes) to 918 MHz radiofrequency radiation - the same frequency range as mobile phones - while the cells were under stress from Alzheimer's-related toxins. The EMF exposure reduced harmful cellular damage and oxidative stress caused by these toxins. This suggests mobile phone radiation might have protective effects against Alzheimer's disease processes.

Researchers exposed adolescent male rats to 900 MHz electromagnetic fields (similar to 2G cell phone frequencies) for one hour daily over 25 days. They found increased numbers of brain neurons in the hippocampus, but these neurons showed cellular damage including disrupted cytoplasm and abnormal staining patterns. This suggests EMF exposure during brain development may trigger compensatory neuron production while simultaneously causing cellular harm.

Researchers exposed participants to Earth-strength magnetic fields while monitoring their brain activity with EEG. They discovered that specific magnetic field rotations caused measurable changes in brain waves (alpha oscillations), but only when the field was oriented as it naturally occurs in the Northern Hemisphere. This suggests humans possess an unconscious magnetic sensing ability similar to migratory animals.

Researchers exposed brain cells called astrocytes to 918 MHz radiofrequency radiation (similar to cell phone signals) along with proteins that cause Alzheimer's disease damage. Surprisingly, they found that the RF exposure actually reduced harmful oxidative stress and protected the cells from damage caused by the Alzheimer's proteins. The study suggests that certain RF frequencies might have therapeutic potential for treating Alzheimer's disease.

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). They discovered this pain-blocking effect works through serotonin receptors in the brain - the same chemical system involved in mood and sleep. The study shows that extremely low frequency magnetic fields can directly alter brain chemistry and pain perception.
