View Original AbstractEight weeks of cell phone radiation exposure altered hundreds of brain genes linked to Alzheimer's and memory loss in mice.
Plain English Summary
Researchers exposed mice to cell phone radiation (2100 MHz) for one hour daily over eight weeks. Even low-level exposures altered brain genes involved in learning and memory, with higher levels affecting over 200 genes linked to Alzheimer's and Parkinson's diseases.
Why This Matters
This study provides molecular-level evidence for what many researchers have long suspected: chronic exposure to cell phone radiation can interfere with normal brain function. The science demonstrates that even at relatively low exposure levels (0.45 W/kg SAR), microwave radiation altered 41 genes involved in learning and memory processes. What makes this particularly concerning is that the highest exposure level tested (3.6 W/kg) is well within the range of everyday cell phone use, yet it disrupted 219 genes linked to neurodegenerative diseases. The reality is that our brains are constantly bathed in these frequencies from our phones, WiFi networks, and other wireless devices. While this was an animal study, the pathways identified are fundamental to mammalian brain function, suggesting similar mechanisms could operate in humans.

Exposure Context
This study used 0.45 1.8 , and 3.6 W/kg for SAR (device absorption):
- 1.1x above the Building Biology guideline of 0.4 W/kg

Where This Falls on the Concern Scale
Study Details
To gain a better understanding of gene expression changes in the brain following microwave exposure in mice. This study hopes to reveal mechanisms contributing to microwave-induced learning and memory dysfunction.
Mice were exposed to whole body 2100 MHz microwaves with specific absorption rates (SARs) of 0.45 W/...
The gene chip results demonstrated that 41 genes (0.45 W/kg group), 29 genes (1.8 W/kg group), and 2...
Long-term, low-level microwave exposure may inhibit learning and memory by affecting protein and energy metabolic processes and signaling pathways relating to neurological functions or diseases.
