Cambridge researchers found no gene activation in human leukemic cells from 60 Hz magnetic fields, contradicting earlier studies.

Plain English Summary

Summary written for general audiences

Cambridge researchers exposed human leukemic cells to 60 Hz magnetic fields at various strengths for 20 minutes, measuring gene activity that could indicate cancer promotion. Despite using improved methods and testing conditions similar to previous studies that found effects, they detected no changes in key cancer-related genes. This negative result adds to the mixed scientific picture on whether power line frequencies can influence cellular processes.

Quick Questions About This Study

This Cambridge study found no activation of cancer-promoting genes (MYC) in human leukemic cells exposed to 60 Hz magnetic fields, even at relatively strong exposures up to 57 microTesla for 20 minutes.
Researchers tested three magnetic field strengths: 0.57, 5.7, and 57 microTesla. The highest level represents fairly strong exposure you might encounter very close to power lines or electrical equipment.
No, despite using very similar conditions to previous studies that reported gene activation, Cambridge researchers could not replicate those findings. They used improved methods and enhanced measurement accuracy but detected no effects.
The human leukemic cells were exposed to 60 Hz magnetic fields for 20 minutes. This duration was chosen to match previous studies that reported rapid gene activation effects.
This study used a new field-exposure system design, protocol modifications to optimize any response, and a novel method for enhanced accuracy in measuring gene activity (mRNA levels).
