Researchers exposed mice to cell phone radiation (1800 MHz) for 30 days and found that 2-hour daily exposures significantly impaired learning and memory performance. The study also tested whether nano-selenium supplements could protect against these cognitive effects, finding that the supplement did help preserve brain function in radiation-exposed mice.

Researchers exposed guinea pigs to 900 MHz cell phone radiation for 7 days and measured damage to liver tissue. The radiation significantly reduced the activity of an important antioxidant enzyme (superoxide dismutase) that protects cells from damage. Surprisingly, two antioxidant supplements that were meant to provide protection actually caused additional cellular damage when combined with radiation exposure.

Researchers exposed mice to cell phone radiation at 1800 MHz (the frequency used by GSM networks) for either 30 or 120 minutes daily over 30 days. Mice exposed for 120 minutes showed significant learning and memory problems, along with brain chemistry changes indicating oxidative stress. When researchers gave the mice nano-selenium supplements, the cognitive damage was largely prevented.

Italian researchers tested 10 modern pacemakers from five manufacturers to see if Wi-Fi signals could interfere with their life-saving functions. They exposed the devices to Wi-Fi radiation at levels five times higher than what's legally allowed for commercial devices. None of the pacemakers showed any performance problems, even at these elevated exposure levels.

Researchers exposed rats to cell phone radiation for 20 minutes daily over three weeks. They found increased hydroxyproline levels in skin tissue, indicating biological changes from electromagnetic exposure. The radiation levels were below current safety limits, suggesting legally compliant phone use may still affect skin.

Researchers exposed male mice to cell phone-level radiation (1800 MHz) for two hours daily over 32 days. The radiation reduced sperm count and testosterone while increasing estradiol and disrupting natural daily hormone rhythms, suggesting potential male fertility risks from cell phone use.
Kim HS et al. · 2014
Korean researchers exposed rats to cell phone radiation at levels similar to what phones emit (2 W/kg SAR) for up to 8 hours daily over two weeks, then examined whether this affected the brain's ability to generate new neurons. They found no significant changes in new brain cell formation in two key brain regions compared to unexposed rats, suggesting that short-term CDMA cell phone radiation exposure doesn't impair neurogenesis in healthy adult brains.

Researchers exposed rats to 900 MHz cell phone radiation for 4 hours daily over 12 days and found it caused liver damage, including cell death and oxidative stress (harmful chemical reactions that damage tissue). The radiation increased harmful compounds and decreased protective antioxidants in liver cells. However, herbal supplements helped protect against this damage, suggesting the liver effects were reversible.

Researchers exposed aquatic plants to 2 GHz radio frequency radiation (similar to cell phone signals) for one hour and measured ultra-precise changes in how the plants grew. The radiation significantly altered the plants' natural growth patterns by 51%, and these changes persisted for at least 2.5 hours after exposure ended. This demonstrates that RF radiation can affect living organisms through non-thermal mechanisms, even in plants.

Researchers exposed Burkitt's lymphoma cells (a type of cancer cell) to 1.8 GHz microwave radiation at levels similar to cell phones for 24 hours. The radiation significantly increased cell death and reduced cell survival, and when combined with a cancer drug called Gemcitabine, the effects were even stronger. This suggests that microwave radiation can affect cancer cells in ways that might interact with cancer treatments.
Zhou H et al. · 2014
Researchers used computer modeling to calculate how much radiofrequency energy (SAR) gets absorbed by different parts of the human brain at various frequencies. They found that the brain absorbs particularly high levels of energy at around 250 MHz and 900-1200 MHz frequencies, likely because the head acts like an antenna that resonates at these specific frequencies. This matters because these frequency ranges overlap with common wireless technologies like cell phones and radio broadcasts.

Russian researchers exposed pregnant rats and their male offspring to cell phone radiation (897 MHz) for 8 hours daily throughout pregnancy and early development. The exposed male rats showed accelerated sexual development, disrupted sperm production with abnormal cell counts at different stages, and decreased sperm viability despite having more mature sperm overall. This suggests that EMF exposure during critical developmental periods can cause lasting reproductive damage that persists into adulthood.
Chen C et al. · 2014
Researchers exposed embryonic brain stem cells to cell phone frequency radiation (1800 MHz) at levels similar to what phones emit during calls. They found that after three days of exposure at the highest level tested, the developing brain cells couldn't properly grow their connecting branches (neurites), which are essential for forming neural networks. This suggests that radiofrequency radiation could potentially interfere with normal brain development in developing embryos.
Lu Y et al. · 2014
Researchers exposed brain cells to 1,800 MHz cell phone radiation and found it triggered inflammation in both microglia and astrocytes, but through different biological pathways. The study identified how radiofrequency exposure activates specific proteins that release inflammatory chemicals, potentially explaining brain inflammation from cell phone use.
Maskey D, Kim MJ · 2014
Researchers exposed mice to cell phone-level radiofrequency radiation for 3 months and found significant reductions in brain proteins essential for neuron survival in auditory processing regions. This suggests chronic RF exposure at typical phone absorption rates may damage neurons responsible for hearing.

Researchers exposed adolescent rats to cell phone radiation (900 MHz) for one hour daily over four weeks and found significant oxidative stress throughout the brain. The radiation increased harmful cellular damage markers and decreased protective antioxidants in key brain regions including the hippocampus, amygdala, and cerebellum. These biochemical changes coincided with altered behavioral performance, suggesting that cell phone radiation may impair brain function through oxidative damage.
Pelletier A et al. · 2014
French researchers exposed young rats to cell phone radiation (900 MHz) for five weeks. The exposed rats slept 15.5% longer and preferred warmer temperatures than unexposed rats, suggesting radiofrequency radiation disrupts natural temperature control and sleep patterns.
Schneider J, Stangassinger M · 2014
German researchers exposed rats to cell phone radiation (900 MHz GSM and 1.966 GHz UMTS) for their entire lives and tested their memory using a social recognition task. Male rats showed significant memory impairments, particularly when exposed to GSM frequencies, while female rats were unaffected. This suggests that chronic exposure to cell phone radiation at levels similar to what phones emit can damage memory function in a sex-specific way.
Yilmaz A et al. · 2014
Turkish researchers exposed rats to mobile phone radiation at levels similar to everyday phone use for 4 weeks, then examined brain tissue for signs of programmed cell death (apoptosis). The exposed rats showed significantly increased levels of proteins that trigger cell death compared to unexposed controls. This suggests that mobile phone radiation may cause brain cells to die prematurely, even at the low power levels typical of normal phone use.
Liu K et al. · 2014
Chinese researchers exposed mouse sperm-producing cells to 1800 MHz cell phone radiation at various power levels for 24 hours to study cellular stress responses. They found that higher radiation levels triggered autophagy (a cellular cleanup process) and increased oxidative stress, with cells using autophagy as a protective mechanism against cell death. This suggests that even when cells don't immediately die from RF exposure, they're still activating stress-response systems to survive.
Narayanan SN et al. · 2014
Researchers exposed adolescent rats to cell phone radiation (900 MHz) for one hour daily over four weeks and found significant brain damage. The radiation caused oxidative stress (cellular damage from harmful molecules) in all brain regions tested, with different areas showing varying degrees of harm. The rats also displayed altered behavior, suggesting the brain damage had functional consequences.
Boga A et al. · 2014
Researchers exposed frog embryos to cell phone radiation (900 and 1800 MHz) for 4-8 hours to study developmental effects. While radiation alone caused minimal harm, combining it with nicotine led to severe abnormalities and death in the embryos. This suggests that smoking while using cell phones may create amplified health risks beyond either exposure alone.
Jirillo E et al. · 2014
Researchers exposed white blood cells from 108 healthy people to cell phone-frequency radiation for up to 24 hours. They found 82% of samples showed significant changes in cell size and shape compared to unexposed cells, suggesting RF radiation directly affects immune system cells.

Researchers exposed mice to cell phone radiation (900-1900 MHz) for 48 minutes daily over six months and examined their kidneys under a microscope. The study found significant structural damage to kidney tissue, including enlarged spaces in filtering units (glomeruli) and damaged tubules that process urine. This suggests that chronic exposure to cell phone-level radiation may harm kidney function at the cellular level.
