Shielding fruit flies from Earth's magnetic field changed lifespan and mitochondria in opposite ways

What the research found
Study (animal). Lisa Chakrabarti, Jacob Reed, and colleagues report in Aging (23 September 2026) that near-zero magnetic shielding changed mitochondrial respiration, superoxide, movement, and lifespan in fruit flies, and the direction depended on mitochondrial health. Flies with a Pink1 defect, a model tied to inherited early-onset Parkinson's, lived about 20% longer when shielded but moved worse. Healthy flies did not gain that lifespan; their movement improved while health span was affected. Not a human aging treatment. Educational research notes.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
