Researchers exposed pregnant and non-pregnant rabbits to cell phone-like radiation for 15 minutes daily for a week to study potential health effects during pregnancy. While the study found no evidence of oxidative stress (cellular damage from harmful molecules), it did detect changes in blood chemistry markers, particularly enzymes that indicate heart muscle stress. The findings suggest that even brief daily exposure to radiofrequency radiation may affect certain biological processes, especially during pregnancy.

Researchers exposed rats to WiFi-frequency radiation for three hours daily over 30 days, finding it impaired spatial memory by reducing glucose uptake in the brain's memory center. Glucose supplements reversed these memory problems, suggesting wireless radiation may interfere with brain energy metabolism.

Researchers exposed male rats to cell phone frequency radiation (1800 MHz) for 2 hours daily over 32 days and measured how this affected their natural daily cycles of melatonin and testosterone production. The radiation disrupted both hormones' normal rhythms, with melatonin being more severely affected than testosterone. This suggests that radiofrequency exposure can interfere with the body's internal biological clock that regulates crucial hormones.

Researchers tested whether people claiming electromagnetic hypersensitivity (EHS) could actually detect cell phone radiation or experience symptoms from it. They exposed 17 EHS subjects and 20 healthy controls to real and fake WCDMA phone signals for 32 minutes while monitoring heart rate, breathing, and symptoms. Neither group showed any physiological changes or could reliably tell when they were being exposed to real radiation.

Researchers exposed rats to WiFi-frequency radiation (2.45-GHz) for one hour daily over four weeks. The radiation caused oxidative damage to skin tissue by increasing harmful compounds and reducing natural antioxidants. This suggests everyday microwave radiation may harm skin health through cellular stress.

Researchers exposed rats to WiFi-frequency radiation (2.45 GHz) for one hour daily over four weeks and measured damage to skin tissue. The radiation significantly increased oxidative stress markers and decreased protective antioxidant enzymes in the skin. However, when rats were given beta-glucan (a natural compound found in oats and mushrooms) before each exposure, it largely prevented this cellular damage.

French researchers exposed young and middle-aged rats to cell phone radiation (900 MHz) for 15 minutes to study brain effects. They found that older rats showed increased brain inflammation and enhanced emotional memory, while younger rats had elevated stress hormones. The study reveals that age significantly affects how the brain responds to radiofrequency radiation.

Researchers used computer simulations to study how 2.45 GHz microwave radiation (the same frequency used in WiFi and microwave ovens) affects protein structure at the molecular level. They found that electromagnetic fields disrupted the normal folding patterns of proteins by interfering with hydrogen bonds that keep proteins stable. This suggests that microwave radiation can alter fundamental biological processes by changing how proteins maintain their shape and function.

Researchers exposed young and adult rats to cell phone radiation (1800 MHz) for two hours daily over 45 days. Both groups showed DNA damage in bone marrow cells, but young rats suffered significantly worse damage that didn't heal during recovery, suggesting children may be more vulnerable.
Aït-Aïssa S et al. · 2012
French researchers exposed pregnant rats and their newborn pups to Wi-Fi signals (2.45 GHz) for two hours daily during pregnancy and early life, then tested the young rats' blood for immune system markers and signs of developmental problems. They found no changes in immune responses or reproductive development at any exposure level tested, including levels much higher than typical human exposure to Wi-Fi.

Researchers exposed rats to electromagnetic radiation from 3G mobile phones for 20 days and examined brain tissue using advanced imaging, biochemical tests, and cellular analysis. They found no significant differences in brain metabolism, antioxidant enzyme activity, or cell death between exposed and unexposed rats. The study suggests short-term 3G phone exposure may not cause detectable brain damage in this animal model.

Researchers exposed rats to cell phone radiation at 1800 MHz for 2 hours and measured a specific marker of DNA damage (8-oxodG) in their urine. They found significant increases in DNA damage markers throughout most of the exposure period, with peak damage occurring 1 hour after exposure began. This suggests that cell phone radiation can cause oxidative damage to DNA, which is a key mechanism linked to cancer development.
Terro F et al. · 2012
French researchers exposed brain cells to cell phone radiation for 24 hours and found it reduced alpha-synuclein protein levels by 24%. This protein is linked to Parkinson's disease. The changes occurred due to slight heating rather than direct cellular damage, showing radiation affects brain proteins even at typical phone exposure levels.
Laudisi F et al. · 2012
Italian researchers exposed pregnant mice to WiFi signals (2.45 GHz) at high levels for 2 hours daily throughout pregnancy to study effects on their offspring's immune system development. They found no detrimental effects on T cell development, immune cell counts, or immune function in the offspring at either 5 weeks or 26 weeks of age. This suggests that prenatal WiFi exposure may not harm developing immune systems, though the study used exposure levels much higher than typical human exposure.
Hong MN et al. · 2012
Researchers exposed human breast tissue cells to cell phone frequencies (837 MHz and 1950 MHz) at high power levels for 2 hours to test whether radiofrequency radiation causes oxidative stress, a type of cellular damage linked to disease. The study found no signs of oxidative stress in the cells, even when exposed to both frequencies simultaneously. This suggests that under these specific laboratory conditions, RF radiation did not trigger the cellular damage processes that scientists look for as early warning signs of health effects.

Researchers exposed immune cells (monocytes) to 2450 MHz microwave radiation - the same frequency used in microwave ovens and Wi-Fi - and found it suppressed their normal inflammatory response. When these cells were stimulated to trigger inflammation, microwave exposure reduced their production of NFκB, a key protein that regulates immune function. This suggests microwave radiation can interfere with your immune system's ability to respond properly to threats.

Researchers tested whether cell phone radiation interferes with laboratory blood tests that measure pregnancy hormones (chorionic gonadotropin). They exposed blood samples to 900MHz radiation from two phones with different power levels and found that the radiation significantly altered the test results, especially at higher concentrations and stronger radiation levels. This suggests that cell phones could interfere with important medical tests in hospital laboratories.

Researchers exposed mouse cells to 916 MHz microwave radiation (cell phone frequency) for 2 hours daily. After 5-8 weeks, cells transformed into cancer-like forms and created tumors when injected into mice within 4 weeks, suggesting microwave radiation can trigger cellular changes leading to cancer.

Polish researchers measured ear temperature in 10 young men during different patterns of cell phone exposure at 900 MHz. They found that continuous phone use for one hour raised ear temperature, while intermittent use (15 minutes on, 15 minutes off) actually lowered it compared to no exposure. The temperature changes persisted for hours after exposure ended, suggesting the body's response depends heavily on how EMF exposure is delivered.
Bourthoumieu S et al. · 2012
Researchers exposed human embryonic cells to cell phone radiation (GSM-900 MHz) for 24 hours at various intensities to see if it would activate p53, a crucial protein that helps protect cells from DNA damage and cancer. The study found no significant changes in p53 expression or activation at any exposure level tested, including levels up to 4 W/kg. This suggests that GSM cell phone radiation may not trigger this particular cellular stress response in embryonic cells.
Ghosn R et al. · 2012
Researchers exposed 29 volunteers to 900 MHz cell phone radiation for 20 minutes while measuring blood flow in their brain arteries using ultrasound technology. They found no changes in blood flow velocity or other circulation measures during or after exposure. This suggests that short-term cell phone use doesn't immediately affect blood circulation in the brain.
Sokolovic D et al. · 2012
Researchers exposed rats to mobile phone radiation for 4 hours daily over 60 days and found the animals lost significant body weight and developed anxiety-like behaviors including agitation and irritability. When rats were given melatonin (a natural hormone) along with the radiation exposure, these negative effects were largely prevented, suggesting melatonin may offer protective benefits against microwave radiation damage.

Researchers measured electromagnetic field exposure in bedrooms over a three-year period (2006-2009) to track how our daily EMF exposure is changing. They found that while electric and magnetic fields from power lines decreased slightly, radiofrequency radiation from wireless devices nearly doubled, increasing from 41.35 to 59.56 microwatts per square meter. This reflects the rapid expansion of cell towers, WiFi networks, and wireless technologies in residential areas during this period.
