Plain English Summary
Researchers exposed brain cells to 50 Hz magnetic fields (household electricity frequency) at different strengths. Higher exposures damaged cell membrane proteins and reduced energy production in mitochondria, leading to decreased cell survival and suggesting power-frequency fields harm basic cellular functions.
Why This Matters
This study provides compelling evidence that power-frequency magnetic fields can cause measurable biological damage at the cellular level. The researchers used advanced spectroscopy techniques to detect molecular changes that wouldn't be visible through standard cell viability tests alone, revealing protein structural damage and mitochondrial dysfunction. What makes this particularly concerning is that the magnetic field strengths used (0.05 to 1.4 milliTesla) overlap with levels you might encounter near high-current electrical equipment, though they're higher than typical household exposures. The fact that these fields altered the fundamental structure of cellular proteins and compromised mitochondrial function demonstrates that EMF effects go far beyond simple heating. This adds to the growing body of evidence that our cells can detect and respond to electromagnetic fields in ways that may have health implications, challenging the outdated assumption that only thermal effects matter.
