Magnetic Field Removal Alters Fruit Fly Lifespan

Scientists at the University of Nottingham shielded fruit flies from Earth's magnetic field in a hypomagnetic chamber. Flies with a Parkinson's-linked Pink1 mutation lived 20 percent longer but moved less; healthy flies died sooner but climbed better. Published in Aging, the study suggests magnetic fields shape mitochondrial aging and may affect astronauts beyond Earth's protective shield.
