Researchers exposed rats to magnetic fields from power lines and measured brain activity using glucose uptake imaging. The magnetic fields increased brain activity in the hindbrain region, but only at specific angles, suggesting brains contain specialized detectors that respond to magnetic field exposure.
Corbacio M et al. · 2011
Researchers exposed 99 people to a strong 60 Hz magnetic field (3 mT) for 30 minutes while they performed memory and thinking tests. While the magnetic field didn't clearly impair cognitive performance overall, it did prevent the normal learning improvement that occurs when people repeat the same memory test. This suggests that power-line frequency magnetic fields may interfere with the brain's ability to form new memories through practice.

Polish researchers exposed rats to 7 milliTesla magnetic fields at 40 Hz (similar to some therapeutic magnetic devices) for either 30 or 60 minutes daily over 10 days. They found that 30-minute exposures increased oxidative stress markers in brain tissue, indicating cellular damage from free radicals. However, 60-minute exposures triggered adaptive mechanisms that appeared to protect against this damage, suggesting the brain can develop tolerance to longer magnetic field exposures.
Chu LY et al. · 2011
Researchers exposed mouse brain tissue to 60 Hz magnetic fields from power lines for three hours and found significant oxidative stress in the cerebellum, including harmful free radicals and depleted vitamin C, suggesting these common electrical frequencies may damage brain cells.
Calabrò E, Condello S, Magazù S, Ientile, R. · 2011
Italian researchers exposed human brain cells to 50 Hz magnetic fields (like power lines) for three hours and found cellular damage including membrane changes, potential DNA harm, and protein breakdown indicating cell death, providing evidence that power-frequency fields can damage neural cells.
Volkow ND et al. · 2011
Researchers measured brain activity in 47 healthy people while they held cell phones to their ears for 50 minutes. They found that brain glucose metabolism (a measure of brain activity) increased by 7% in the area closest to the phone's antenna. While the study authors called the health significance 'unknown,' this demonstrates that cell phone radiation does measurably affect brain function at typical usage levels.
Trosić I et al. · 2011
Researchers exposed rats to cell phone radiation (915 MHz) for one hour daily over two weeks. DNA damage was found in liver and kidney cells using comet assay testing. This suggests short-term radiofrequency exposure at cell phone levels can cause genetic damage in organs.
Sirav B, Seyhan N · 2011
Researchers exposed rats to cell phone radiation (0.9 GHz) for 20 minutes to test brain protection. The radiation made the blood-brain barrier leaky in male rats only, allowing blood proteins into brain tissue. This suggests phone radiation may compromise brain defenses differently between sexes.
Partsvania B, Sulaberidze T, Shoshiashvili L, Modebadze Z · 2011
Scientists exposed mollusk nerve cells to 900 MHz cell phone radiation for one hour. While the neurons still fired normally, they responded faster to stimulation after exposure. This shows cell phone radiation can alter how quickly individual nerve cells process information, even temporarily.
Papageorgiou CC et al. · 2011
Researchers exposed 30 people to Wi-Fi signals while they performed a mental task that required focus and working memory, measuring brain activity through electrodes on the scalp. They found that Wi-Fi exposure significantly reduced brain activity (measured by P300 brain waves) in men but not women during tasks requiring mental inhibition. This suggests Wi-Fi radiation may impair attention and working memory functions differently based on gender.
Ntzouni MP, Stamatakis A, Stylianopoulou F, Margaritis LH. · 2011
Researchers exposed mice to cell phone radiation at human-level intensities and tested their memory recognition abilities. Mice showed significant memory problems, especially when exposed during the 17-day period when memories form. This suggests mobile phone radiation may interfere with the brain's memory formation processes.
Noor NA, Mohammed HS, Ahmed NA, Radwan NM · 2011
Researchers exposed rats to 900 MHz cell phone radiation daily and found significant disruptions in brain neurotransmitters (chemical messengers between brain cells). Both adult and young animals showed altered brain chemistry patterns across multiple brain regions, potentially explaining neurological symptoms some people experience from mobile phone use.
Masuda H et al. · 2011
Researchers exposed rat brains to cell phone-frequency radiation and found it increased both brain temperature and blood flow. Higher radiation levels caused greater effects. This shows radiofrequency radiation triggers measurable biological changes in brain tissue, including the brain's natural response to heating.
Lowden A et al. · 2011
Researchers exposed 48 people to cell phone radiation (884 MHz) for 3 hours before bedtime, then monitored their brain waves during sleep. The radiation exposure reduced deep sleep (slow-wave sleep) by 12% and increased lighter Stage 2 sleep, while also altering brain wave patterns throughout the night. This suggests that cell phone radiation can disrupt the quality of sleep even after exposure ends.
Liu ML, Wen JQ, Fan YB. · 2011
Researchers exposed rat brain neurons to 1800 MHz cell phone radiation for 24 hours and found it caused significant cell death. However, when they treated the neurons with green tea polyphenols (natural compounds found in green tea), the protective compounds prevented much of the radiation-induced damage. This suggests that certain natural antioxidants might help protect brain cells from the harmful effects of cell phone radiation.
Leung S et al. · 2011
Researchers tested how 2G and 3G cell phone signals affect brain function in teenagers and adults during 55-minute exposures. They found 3G signals reduced memory accuracy in teenagers, while both signal types altered brain wave patterns in all age groups, showing measurable impacts on brain processing.
Kwon MS et al. · 2011
Finnish researchers exposed 13 young men to typical cell phone radiation for 33 minutes and used brain scans to measure energy use. They found glucose metabolism (brain fuel) significantly decreased in specific regions near the phone, showing even brief exposure measurably changes brain function.
Kesari KK, Kumar S, Behari J. · 2011
Researchers exposed young rats to 900 MHz mobile phone radiation (the same frequency used by many cell phones) for 2 hours daily over 45 days. They found significant brain changes including increased oxidative stress (cellular damage from unstable molecules), decreased antioxidant protection, and elevated markers associated with cell death. The study suggests that prolonged mobile phone radiation exposure may harm brain tissue through oxidative damage.
Favre D · 2011
Researchers placed active mobile phones near honeybee colonies and recorded the bees' sounds to see if cell phone radiation affected their behavior. They found that phones operating at 900 MHz caused bees to produce 'worker piping' signals, which normally indicate either preparation for swarming or that the colony is under stress. This suggests that cell phone radiation can disrupt normal bee communication and behavior patterns.
Dragicevic N et al. · 2011
Researchers exposed mice to 918 MHz electromagnetic fields daily for one month. The treatment dramatically boosted brain cell energy production by 50-150% in Alzheimer's mice and improved function in normal mice, suggesting EMFs might protect against cognitive decline.
Carballo-Quintás M et al. · 2011
Researchers exposed rats to cell phone-level 900 MHz radiation for 2 hours, then gave them a seizure-inducing drug called picrotoxin. They found that the combination of radiation and the drug caused significantly more brain cell activation and inflammatory responses than either exposure alone. This suggests that EMF radiation may make the brain more vulnerable to other toxic substances.
Trosić I et al. · 2011
Researchers exposed rats to cell phone radiation (915 MHz) for one hour daily over two weeks and measured DNA damage in brain, liver, and kidney cells using the comet assay. They found measurable DNA breaks in liver and kidney cells, with slight increases in brain cells compared to unexposed control animals. This suggests that repeated exposure to cell phone-type radiation can cause genetic damage at the cellular level.
Peter Denchev et al. · 2010
Researchers analyzed whether adding ECG screening to routine checkups could prevent sudden cardiac death in children prescribed ADHD stimulant medications. They found that ECG screening would prevent 13 deaths per 400,000 children treated, but at a high cost of $1.2-1.6 million per life saved. The screening showed borderline cost-effectiveness compared to current standard care.

This appears to be a climate change report that was incorrectly categorized as EMF research. The abstract describes an IPCC climate assessment covering physical climate science, impacts, adaptation, and mitigation strategies. No electromagnetic field research or health effects were actually studied in this document.

This cancer research study investigated selumetinib, a drug that blocks MEK proteins involved in cell growth signaling. Researchers developed genetic signatures to predict which tumors would respond to this targeted therapy, finding that simple mutation tests weren't enough to determine treatment effectiveness. The work aims to improve personalized cancer treatment by better identifying patients likely to benefit from MEK inhibitor drugs.
