Researchers analyzed 10 studies involving 1,492 sperm samples to examine how mobile phone radiation affects male fertility. They found that exposure to cell phone radiation was linked to reduced sperm movement (8.1% decrease) and viability (9.1% decrease). This matters because fertility problems affect 14% of couples globally, and sperm quality has been declining in many countries.

French researchers studied 253 glioma patients, 194 meningioma patients, and 892 healthy controls to examine mobile phone use and brain tumor risk. They found no increased risk for typical users, but heavy users (896+ hours lifetime or 18,360+ calls) showed nearly triple the risk for both tumor types. The study adds to growing evidence linking intensive mobile phone use to brain tumors.

This study examined mortality data from 73,051 UK electricity supply workers (1973-2010) to investigate whether occupational exposure to extremely low-frequency magnetic fields was associated with increased risk of Alzheimer's disease, motor neurone disease, or Parkinson's disease. The analysis found no statistically significant trends linking magnetic field exposure (assessed by lifetime, recent, or distant exposure categories) to increased risk of any of these three neurodegenerative diseases.

Researchers exposed human bone marrow stem cells to 50 Hz electromagnetic fields (the same frequency as power lines) at 1 milliTesla for 8 days and found the fields triggered the cells to develop into neurons. The study identified a specific protein called Egr1 that controls this transformation, and showed that transplanting these EMF-created neurons helped reduce symptoms in mice with neurodegenerative diseases.

This study examined how low frequency electromagnetic fields affect autophagy (cellular self-cleaning processes) in human neuroblastoma cells through direct exposure. The research investigated modulation of autophagy pathways as a cellular response to electromagnetic field exposure.

This cross-sectional study of 854 electric power plant workers in China examined how daily occupational EMF exposure affects sleep. Researchers found that workers with longer daily EMF exposure had up to 68% higher risk of poor sleep quality compared to those with shorter exposure times. Notably, EMF exposure damaged sleep quality specifically, not sleep duration, suggesting it disrupts the restorative aspects of sleep rather than how long people sleep.

This study investigated how melatonin protects rat cerebellar granule cells against increases in sodium channel currents induced by extremely low-frequency electromagnetic field (ELF-EMF) exposure. The researchers found that melatonin inhibits ELF-EMF-induced sodium current increases through an MT2 receptor-dependent mechanism involving intracellular calcium release from ryanodine-sensitive stores.

This laboratory study exposed neurons from newborn rats to pulsed electromagnetic fields at 50 Hz (common electrical frequency) and 1 milliTesla for 2 hours. The PEMF exposure increased production of BDNF, a protein critical for nerve growth and repair, by triggering calcium channels and cellular signaling pathways. The findings demonstrate a biological mechanism by which EMF can directly alter neuronal function at the cellular level.

Turkish researchers exposed rats to extremely low-frequency electric fields (50 Hz) at different intensities for 2-4 weeks and measured brain responses using mismatch negativity, a test of auditory processing. The study found that stronger electric fields (18 kV/m) reduced brain response amplitudes after 4 weeks of exposure, accompanied by increased oxidative damage markers in brain tissue.

This study examined the pharmacological basis of response latency changes in the hot plate test following whole-body static magnetic field exposure in the land snail Helix pomatia. The research investigated how static magnetic field exposure affects pain-related responses and the underlying pharmacological mechanisms in this organism.

Researchers exposed human brain cells to a 50 Hz pulsed magnetic field at 1 milliTesla while simultaneously treating them with hydrogen peroxide (a substance that damages DNA). They measured DNA breaks and cell health over 72 hours and found that the magnetic field exposure did not increase the DNA damage or cell death caused by the oxidative stress. This suggests that this specific type of extremely low frequency magnetic field doesn't make cells more vulnerable to other harmful agents.

This study examined the effects of extremely low frequency (ELF) electromagnetic field exposure on cognitive function in mice, investigating mechanisms involving glutamate levels, MAPK pathway activation, and CREB phosphorylation in the hippocampus. The researchers found that ELF exposure caused cognitive impairment through these molecular alterations, and that procyanidins extracted from lotus seedpods could reverse these effects.

This study investigated whether pulsed electromagnetic field (PEMF) stimulation could promote osteogenic (bone cell) differentiation in amniotic epithelial cells (AECs) isolated from human placenta. The researchers found that PEMF alone and osteo-induction medium alone each induced osteogenic differentiation, and that combining both approaches produced synergistic effects, with upregulation of key osteogenic genes including BMP-2, Runx2, and β-catenin.

Researchers exposed human brain cancer cells to static magnetic fields (SMFs) of 80 mT, both alone and combined with X-ray radiation. They found that static magnetic fields actually reduced DNA damage caused by X-rays and helped protect cellular structures called mitochondria. This suggests magnetic fields might have protective effects under certain conditions.

Researchers exposed human bone marrow stem cells to 50 Hz electromagnetic fields (the same frequency as power lines) and found these fields triggered the cells to transform into neurons. The key discovery was that a specific protein called Egr1 controls this transformation process. When these EMF-induced neurons were transplanted into mice with brain diseases, the animals showed significant improvement.

Researchers exposed neonatal rat nerve cells to 50Hz pulsed electromagnetic fields (the same frequency as electrical power lines) at 1 milliTesla for 2 hours.

This 2014 study examined how gadolinium (Gd) and extremely low-frequency electromagnetic fields (ELF-EMF) affect human lymphocytes in culture. The researchers found that Gd alone caused concentration- and time-dependent cell death and DNA damage, and that exposure to 0.8 mT ELF-EMF at 60 Hz further enhanced these cytotoxic and genotoxic effects.

Researchers analyzed 52,680 Danish children to understand how cell phone exposure during pregnancy affects childhood behavioral problems, focusing on differences between siblings. They found that traditional studies may overestimate risks because cell phone usage patterns changed dramatically over time, with newer siblings having different exposure profiles than older ones. The study reveals important methodological challenges in EMF research that could affect how we interpret health risks.

This study examined how daily 1800-MHz radiofrequency exposure affected reproductive markers in male rats, with exposures timed at different circadian phases. The researchers found that RF exposure disrupted circadian rhythms and decreased testosterone levels, sperm production, and sperm motility, with more pronounced effects when exposure occurred at ZT0 (lights-on).
