Researchers exposed chick embryos to 50-Hz magnetic fields (the type from power lines) during development and tested their memory after hatching. Chicks exposed to magnetic fields showed impaired memory formation, but only when they were stressed during testing. This suggests that electromagnetic field exposure during development may make the brain more vulnerable to memory problems under stressful conditions.

Researchers exposed rats with spinal cord injuries to extremely low frequency magnetic fields (50 Hz, 17.9 microT) for 2 hours daily over 8 weeks. The magnetic field exposure restored normal food intake, water consumption, and body weight in the paralyzed rats, all of which had decreased after their spinal cord injuries. This suggests that specific magnetic field frequencies might help support basic physiological functions in spinal cord injury patients.

Researchers measured β-trace protein (a brain-produced protein that helps regulate sleep) in 62 young adults and found that people who used wireless phones longer had lower levels of this protein in their blood. When participants were exposed to cell phone radiation for 30 minutes in a lab setting, their β-trace protein didn't change significantly, but unexposed participants showed increased levels over the same time period.

Researchers measured beta-trace protein, a key enzyme that produces the brain's natural sleep hormone, in 62 young adults who used wireless phones. They found that people who had used wireless phones longer had lower levels of this sleep-promoting protein in their blood. This provides a potential biological explanation for why some people experience sleep problems when exposed to cell phone radiation.

Turkish researchers exposed rats to 1800 MHz cell phone radiation (the same frequency used by GSM networks) for 20 minutes daily over a month to test for DNA damage in bladder cells. They found no increase in micronuclei (cellular markers of genetic damage) compared to unexposed control rats. This suggests that short-term exposure to GSM radiation at these levels did not cause detectable genetic damage to bladder cells.

Scientists used computer models to study how much electromagnetic radiation developing embryos absorb from radio frequencies. They found embryos absorbed up to 0.08 watts per kilogram when exposed to current safety guideline levels, helping researchers understand potential effects from everyday wireless devices.
Grigor'ev IuG et al. · 2010
Researchers exposed rats to WiFi-frequency radiation (2450 MHz) for 7 hours daily over 30 days at non-heating levels. They found clear signs of oxidative stress in blood, indicating cellular damage from harmful free radicals. This suggests low-level microwave exposure can damage cells without heating tissue.

Researchers exposed male rabbits to mobile phone radiation (800 MHz) for 8 hours daily over 12 weeks and found significant changes in sexual behavior, including reduced ejaculation frequency and increased mounting without ejaculation. The study was later retracted by the journal, which means the findings were deemed unreliable due to methodological or other serious concerns.
Campisi A et al. · 2010
Italian scientists exposed brain cells to cell phone radiation and found that pulsed signals caused DNA damage and increased harmful molecules called free radicals after 20 minutes. Continuous waves showed no effects, suggesting modulated wireless signals may harm brain cells through non-heating mechanisms.

Researchers exposed pregnant and non-pregnant rabbits to cell phone radiation for 15 minutes daily over seven days. Both groups showed significant DNA damage and cellular stress in brain tissue, while newborns were unaffected. This demonstrates measurable biological harm from everyday cell phone exposure levels.
Xu S et al. · 2010
Researchers exposed brain neurons to cell phone radiation at 1800 MHz and found it damaged mitochondrial DNA, the genetic material in cells' energy centers. The radiation increased DNA damage markers and reduced healthy mitochondrial genes. This suggests cell phone radiation may harm brain cells' power-producing structures.
Arendash GW et al. · 2010
Researchers exposed mice to cell phone radiation (918 MHz) for one hour daily over eight months. The exposure improved memory and reduced Alzheimer's-related brain plaques in both normal and Alzheimer's-prone mice, suggesting certain electromagnetic fields might benefit brain health.
Fragopoulou AF et al. · 2010
Greek researchers exposed mice to cell phone radiation (900 MHz) for 2 hours daily over 4 days. The exposed mice showed significant deficits in learning and remembering spatial information compared to unexposed mice, suggesting cell phone radiation may impair brain memory functions.

Researchers exposed 41 people to cell phone radiation for 30 minutes and found it increased levels of transthyretin (TTR), a protein that helps protect the brain from Alzheimer's disease by clearing harmful plaques. In a separate study of 313 people, longer-term phone use was also linked to higher TTR levels. This suggests cell phone radiation might actually trigger a protective response in the brain against Alzheimer's disease.
Maskey D et al. · 2010
Researchers exposed mice to cell phone frequency radiation (835 MHz) for up to one month and examined brain tissue in the hippocampus, a region critical for memory and learning. They found significant damage to calcium-binding proteins and near-complete loss of pyramidal brain cells in the CA1 area after one month of exposure. This cellular damage could disrupt normal brain functions including memory formation and neural connectivity.
Maskey D et al. · 2010
Researchers exposed mice to cell phone radiation (835 MHz) for 8 hours daily over 3 months. The radiation caused brain cell death and inflammation in the hippocampus, the brain region responsible for memory and learning, suggesting chronic cell phone use may damage critical brain structures.

Researchers exposed adult female rats to 900 MHz radiofrequency radiation (the same frequency used by many cell phones) for one hour daily over 28 days. They found that exposed rats had significantly fewer Purkinje cells in their cerebellum compared to unexposed rats. Purkinje cells are critical brain neurons that control movement, balance, and coordination, making their loss potentially serious for neurological function.
Xu S et al. · 2010
Researchers exposed brain neurons to cell phone-frequency radiation (1800 MHz) at levels similar to heavy phone use and found it damaged the DNA inside cellular powerhouses called mitochondria. The radiation increased markers of DNA damage by 24 hours and reduced the neurons' ability to produce energy. Importantly, the antioxidant melatonin completely prevented this damage, suggesting oxidative stress was the underlying cause.

Researchers exposed 20 volunteers to mobile phone pulses (217 Hz frequency) while monitoring brain activity. Advanced analysis detected measurable brain responses in 90% of participants, suggesting mobile phones create detectable changes in brain function that standard testing methods miss.
Cuccurazzu B et al. · 2010
Researchers exposed mice to 50 Hz electromagnetic fields (power line frequency) for up to seven hours daily over one week. The exposure significantly increased new brain cell growth in the hippocampus, the brain region responsible for memory formation, suggesting certain EMF exposures may enhance rather than harm brain function.

Researchers exposed rats to 50 Hz magnetic fields (the type from power lines) for either 5 days or 4-6 weeks to study stress effects. They found that long-term exposure led to depression-like behavior, elevated stress hormones, and higher blood glucose levels, while short-term exposure showed no effects. This suggests that chronic exposure to magnetic fields may act as a mild stressor that could contribute to depression and metabolic problems.
Frahm J, Mattsson MO, Simkó M. · 2010
Researchers exposed mouse immune cells to 50 Hz magnetic fields and found the exposure triggered cellular stress responses and increased harmful molecules called reactive oxygen species. This suggests magnetic fields can activate immune cells and disrupt normal cellular processes even without killing cells.

Scientists exposed human blood cancer cells to electromagnetic fields from power lines for three hours. The fields protected healthy cells from dying but increased cell death in already-stressed cells. This shows that EMF effects depend on the cell's existing health condition.
Lee HM et al. · 2010
Researchers exposed human spinal disc cells to 60 Hz magnetic fields at 1.8 millitesla for 72 hours to see how electromagnetic fields affect cell growth. They found that the magnetic fields stimulated DNA synthesis and increased cell proliferation without causing cell damage. This suggests that specific EMF exposures might have therapeutic potential for treating degenerative disc disease by promoting healthy cell growth.
