Researchers exposed female mice to 20 kHz magnetic fields at 360 µT (similar to wireless car charging systems) for 24 hours daily over 10 months. While the mice showed no changes in growth, survival, or tumor rates, they demonstrated altered behavior including improved balance performance and reduced exploratory activity.

This study examined the effects of radiofrequency electromagnetic field (RF-EMF) exposure on developing hippocampal neurons in early postnatal mice exposed to 4.0 W/kg SAR for 5 hours daily over 4 weeks. The research found that RF-EMF exposure decreased dendritic spine density (particularly mushroom-type spines), reduced BDNF and glutamate receptor expression, hindered neurite outgrowth, and impaired memory function in exposed mice.

Researchers exposed rats to 915 MHz RFID signals at 2 watts per kilogram and found changes in serotonin metabolism, a brain chemical that regulates mood and behavior. The study shows these neurochemical changes occurred even at exposure levels not officially considered hazardous. This suggests RFID technology may affect brain chemistry at power levels currently deemed safe.

Researchers exposed rats to 2.1 GHz radiofrequency radiation at two different power levels for one week and tested their learning abilities. Rats exposed to the higher dose (65 V/m) showed impaired spatial memory and significantly reduced levels of key brain chemicals needed for learning and memory in the hippocampus. This suggests that even short-term exposure to this frequency can affect brain function in a dose-dependent manner.

Researchers exposed rats to 900 MHz cell phone radiation for one hour daily over 28 days and found significant damage to hippocampal brain neurons, including cell death and structural damage. Two natural compounds, curcumin and Garcinia kola, provided protective effects against this brain damage, while gum arabic showed no protection.
Delen K et al. · 2021
Turkish researchers exposed male rats to 2,600 MHz radiofrequency radiation (similar to 4G/5G frequencies) for 30 minutes daily over 30 days and found significant brain damage including reduced antioxidant levels and increased cell death. The study also tested whether melatonin supplements could protect against this damage, finding that high-dose melatonin reduced many of the harmful effects.

This study examined how methodological factors influence the detection of radiofrequency electromagnetic field (RF-EMF) effects on EEG alpha power in 36 adults exposed to sham, low, and high RF-EMF conditions. The researchers found that alpha power increases were greater during eyes-open versus eyes-closed EEG recordings and showed a trend toward larger increases later in the exposure period, suggesting that previous studies using eyes-closed conditions or shorter exposure durations may have failed to detect RF-EMF effects.

European researchers studied over 3,200 children and teens to measure radiofrequency radiation doses to their brains from phones, tablets, and other wireless devices. They found that higher brain radiation exposure was linked to lower non-verbal intelligence scores in 9-11 year olds. The effect was small but consistent across multiple countries.
Bueno-Lopez A et al. · 2021
Researchers exposed 30 young men to Wi-Fi radiation (2.45 GHz) all night while they slept to test effects on memory formation. Surprisingly, participants performed slightly better on word memory tasks after Wi-Fi exposure, though brain activity measurements showed no changes. The authors suggest this unexpected finding may be random rather than meaningful.
Akakin D et al. · 2021
Researchers used EEG brain wave measurements to compare brain activity when participants were and weren't using mobile phones. The study aimed to determine if radiofrequency radiation from phones during calls affects nervous system function. This research addresses ongoing questions about whether phone radiation causes measurable changes in brain activity.

This appears to be a physics research study involving a large international collaboration of scientists, likely investigating particle detection or electromagnetic phenomena. The extensive author list suggests a major experimental physics project, though specific EMF-related findings are not detailed in the available information.

Italian researchers exposed brain cancer cells to 1950 MHz radiofrequency radiation and found it actually reduced DNA damage from a toxic chemical, both in directly exposed cells and in nearby unexposed cells through a 'bystander effect.' The study suggests RF radiation may trigger protective cellular responses involving heat shock proteins.
Tohidi F et al. · 2021
Researchers exposed mice to mobile phone radiation for different daily durations over 30 days and measured changes in brain genes that control cell death. They found that radiation exposure altered the balance of Bax and Bcl2 genes in the hippocampus (the brain's memory center), with longer exposures showing the most dramatic shifts toward cell death pathways. This suggests mobile phone radiation can disrupt normal brain cell survival mechanisms.

This study exposed four-week-old mice to 1800 MHz radiofrequency fields for three weeks during morning and evening periods to investigate effects on testicular development. The exposure resulted in decreased testicular weight, sperm production, and testosterone levels, along with dysregulation of long non-coding RNA expression, with morning exposure affecting 615 lncRNAs compared to 183 for evening exposure.

Researchers exposed pregnant mice to 900 MHz cell phone radiation for 8 hours daily over 10 days and found significant increases in oxidative stress markers in their blood. The study showed that vitamin C supplementation could prevent this radiation-induced cellular damage, suggesting antioxidants may offer protection against EMF exposure during pregnancy.
Li M et al. · 2021
This study appears to be about gravitational wave detection from space-based instruments, not electromagnetic field health effects. The research catalogs gravitational waves from colliding black holes and neutron stars detected by Advanced LIGO and Virgo observatories. This is unrelated to EMF health research and focuses on astrophysical phenomena.

Researchers exposed blood cells from 5 men to 900 MHz cell phone frequency radiation for up to 90 minutes, analyzing changes in 667 microRNAs that regulate gene expression. While they initially found 2 microRNAs that appeared to respond to EMF exposure, these changes could not be reproduced when the experiment was repeated 2 years later. The study found no consistent evidence that brief 900 MHz exposure alters microRNA expression in human blood cells.
Kundu A et al. · 2021
This study examined molecular responses in rice plants following a single 2.5-hour exposure to 1837.50 MHz electromagnetic radiation at 2.75 mW/m². The researchers found significant upregulation of calmodulin and phytochrome B gene expressions when measured immediately after exposure.

This study examined the effects of long-term evolution (LTE) radiofrequency electromagnetic fields (1760 MHz at 4 W/kg SAR) on neuroblastoma cell proliferation in SH-SY5Y cells. The researchers found that RF-EMF exposure decreased cell growth and proliferation by inducing cellular senescence through the Akt/mTOR pathway, which activated p53 and its downstream CDK inhibitors, ultimately delaying the cell cycle without causing DNA damage or apoptosis.

This appears to be a physics collaboration study from the COSINE-100 experiment, which typically involves dark matter detection research rather than EMF health effects. The study information provided lacks key details about EMF exposure parameters, biological endpoints, or health findings. Without access to the actual methodology and results, no meaningful conclusions about EMF health effects can be drawn.

This study examined whether long-term evolution (LTE) radiofrequency electromagnetic field (EMF) exposure affects DNA damage in skin cells and mouse models. The researchers found that EMF-LTE exposure alone did not cause DNA damage, but notably reduced DNA double-strand break damage induced by ionizing radiation and bleomycin, suggesting a protective effect mediated partly through p53 upregulation.

Researchers exposed rats to 2.1 GHz radiofrequency radiation (similar to 3G cell towers) at two different intensities for one week. Higher exposure levels (65 V/m) significantly impaired the rats' spatial memory and learning abilities, while also reducing key brain chemicals needed for memory formation in the hippocampus.
