Geomagnetic field alters mitochondrial aging

A laboratory study shielding fruit flies from Earth's magnetic field produced genotype‑specific changes: Pink1 mutant flies (mitochondrial dysfunction model) lived ~20% longer but showed worse locomotor performance, while wildtype flies had improved performance but shorter lifespan. The effects are tied to changes in reactive oxygen species (ROS) production, suggesting magnetic exposure modulates mitochondrial stress responses. — If ambient magnetism measurably shifts mitochondrial ROS and lifespan, researchers and policymakers should consider geomagnetic environment as a factor in aging studies, clinical translation, and human health in altered magnetic regimes (e.g., space travel).
