Additive Effects of Millimeter Waves and 2-Deoxyglucose Co-Exposure on the Human Keratinocyte Transcriptome

This study reveals a concerning pattern: 5G frequencies may not cause obvious damage to healthy cells, but they can interfere with how cells respond to metabolic stress. The 60.4 GHz frequency tested here sits squarely in the range planned for 5G small cell networks that will blanket urban areas. What makes this particularly relevant is that our cells face metabolic stress daily from pollution, poor diet, illness, and aging. The research shows that millimeter waves can disrupt six key genes that normally help cells cope with such stress, including genes that regulate immune responses and cellular communication. Put simply, 5G frequencies might not break healthy cells, but they could prevent stressed cells from properly defending themselves. The power density used (20 mW/cm²) is actually lower than what you'd experience very close to a 5G small cell antenna, making these findings more concerning, not less. The researchers themselves noted questions about 'potential impact of long-term or chronic MMW exposure on metabolically stressed cells' - exactly the kind of real-world exposure millions will soon face.
