Researchers exposed mice to WiFi radiation (2.45 GHz) for 16 weeks using both household routers and laboratory equipment to simulate real-world conditions. The exposed mice showed increased movement activity and reduced DNA methylation in their brains, but no visible structural brain damage. This suggests WiFi radiation may cause subtle biological changes even without obvious tissue damage.

This study examined whether long-term exposure to radiofrequency electromagnetic fields (1950 MHz, 5 W/kg for 6 months) could reduce cognitive dysfunction in 5×FAD mice with Alzheimer's disease through microglial regulation. The researchers found that RF-EMF exposure ameliorated cognitive impairment and amyloid-β deposition, with reduced expression of microglial markers (Iba1, CSF1R) and genes related to microgliosis and pro-inflammatory responses.

Researchers studied how extremely low-frequency electromagnetic fields (ELF-EMF) and ketamine affect depression-like behavior, learning, memory, and brain proteins in animals experiencing chronic stress. The study examined multiple brain markers including GFAP, caspase-3, p53, BDNF, and NMDA receptors. This research explores whether ELF-EMF exposure might influence mental health outcomes and brain function under stress conditions.

Researchers exposed male mice to a combination of electromagnetic pulse (EMP) and 4.9 GHz radiofrequency radiation for one week. The combined exposure triggered anxiety-like behavior, altered brain chemistry (reducing serotonin and increasing S100B stress markers), and caused cellular damage in brain regions controlling emotion. This suggests that multiple EMF sources may interact to affect mental health in ways that single exposures might not reveal.

Scientists tested zebra finches' ability to navigate using Earth's magnetic field when exposed to radio frequency radiation at extremely low levels (10 nT). The study found that RF fields don't eliminate birds' magnetic sensing but alter it in complex ways, with different types of RF creating different navigation patterns. This reveals that even very weak RF pollution can interfere with natural biological navigation systems.

Researchers exposed rats to Wi-Fi radiation and found it damaged brain cells in the hippocampus, the brain region crucial for memory and learning. However, rats that exercised regularly before and during Wi-Fi exposure showed significantly less brain damage. The study suggests physical exercise may help protect against Wi-Fi-related brain harm.

This study examined the effects of 0.138 terahertz (THz) radiation on neuronal growth and synaptic transmission in hippocampal tissue. The researchers found that cumulative THz radiation promoted neuronal cytosol growth, increased dendritic spine density, and improved synaptic transmission efficiency in the CA1 region, with effects persisting for over 10 minutes after exposure ended.

Researchers exposed 60 young men to radiofrequency EMF (430 MHz at 10.75 W/m²) and low-frequency noise simultaneously for 30 minutes, measuring cognitive performance. The combined exposure significantly slowed reaction times and increased brain activity in areas responsible for mental workload, showing these environmental stressors interact to impair cognitive function. This matters because many work environments expose people to both EMF and noise at these levels daily.

This study examined the effects of S-band microwave radiation (30 mW/cm² for 35 minutes) combined with stress conditions on rats, measuring cardiac structural damage, mitochondrial dysfunction, oxidative stress, hormonal changes, and behavioral outcomes. The researchers found that microwave exposure induced myocardial fiber disorganization, mitochondrial cavitation, increased stress hormones, altered heart rate variability, anxiety/depression-like behaviors, and increased expression of stress-related proteins (JNK, p-JNK, HSF1, and NFATc4).

Researchers exposed rats to S-band microwave radiation (30 mW/cm² for 35 minutes) to simulate occupational exposure conditions. The study found significant heart damage including disrupted muscle fibers, mitochondrial dysfunction, and oxidative stress, plus psychological effects like anxiety and depression. This suggests that high-power microwave exposure can cause both physical heart damage and mental health impacts.

This 2023 study investigated nonthermal effects of 2856-MHz radiofrequency radiation (RFR) on the mouse nervous system. The researchers found that RFR exposure within thermal noise limits induced spatial memory impairment through reduced dopamine release in the hippocampus and enhanced glutamate-mediated neuronal calcium activity, with effects reversing after RFR termination.

This cross-sectional study of 1,101 Spanish adolescents examined associations between electronic device use (cell phones, video games, social media applications) and sleep outcomes. The study found that cell phone use was most associated with sleep duration and problems, with sex-specific differences; WhatsApp use was associated with sleep-related problems in girls, and psychosocial health emerged as a significant variable in the models.

Researchers exposed young male rats to electromagnetic fields from multiple cell phones and tested their learning and memory abilities. The EMF exposure improved short-term learning but impaired long-term memory formation. Treatment with lipoic acid (an antioxidant) reversed these memory problems and restored normal brain function.

Researchers exposed elderly mice to low-frequency pulsed electromagnetic fields (PEMFs) from a therapeutic device for just 15 minutes daily over four weeks. The treated mice showed measurably better coordination, movement, immune function, and reduced oxidative stress and inflammation compared to untreated elderly mice. These findings suggest that certain carefully controlled PEMF exposures may counter some aging-related health declines, at least in laboratory conditions.

Turkish researchers exposed rats to cell phone frequencies (900, 1800, and 2100 MHz) for 3 hours daily for one month and found increased spacing between brain cells in both brain hemispheres. The study used electron microscopy to measure these cellular changes, with 1800 MHz showing the strongest effects in the right brain and 2100 MHz in the left brain. This suggests cell phone radiation may alter brain tissue structure at the microscopic level.

This molecular dynamics simulation study investigated how terahertz waves affect the structure of amyloid-beta (Aβ42) peptides at different aggregation states. The researchers found that terahertz waves at 42.55 THz enhanced structural interactions in Aβ42 monomers and dimers by resonating with specific molecular vibration modes, increasing β-sheet content and binding energy between monomers, while also mildly stabilizing tetrameric protofibril structures.

Researchers exposed rats with vascular dementia to WiFi radiation (2.45 GHz) for 2 hours daily over 45 days and found it improved their learning, memory, and brain cell survival. The WiFi exposure helped restore normal brain function and increased neuron density in the hippocampus, the brain's memory center. This unexpected finding suggests low-level microwave radiation might have therapeutic potential for certain brain conditions.

Chinese researchers used computer simulations to study how terahertz (THz) electromagnetic waves affect the unfolding of RNA hairpins, including structures from SARS-CoV-2. They found that specific THz frequencies (4-41.2 THz) can either speed up or slow down the unfolding of these genetic structures, depending on the exact frequency used. This matters because it shows THz waves can directly influence fundamental genetic processes like replication and transcription.

Researchers exposed lettuce plants to wireless radiation from DECT phones (1890-1900 MHz) and WiFi (2.4 and 5 GHz) in both greenhouse and outdoor settings. Plants exposed outdoors showed reduced photosynthesis efficiency, earlier flowering, and impaired stress response genes, while greenhouse plants were largely unaffected. This suggests RF-EMF may interfere with plants' ability to handle environmental stress.

Researchers exposed 360 Ixodes ricinus ticks to 900 MHz electromagnetic radiation at two different intensities and measured changes in neuropeptide gene expression in their nervous systems. Female ticks showed significant decreases in all four tested neuropeptide transcript levels after 1 to 3 hours of higher-intensity exposure, while male ticks showed consistent downregulation of allatotropin genes. This is the first study documenting how electromagnetic radiation affects tick neurophysiology, revealing that even arthropods experience measurable biological changes from RF-EMF exposure.
