University of Nottingham study links Earth's magnetic field to aging

New research from the University of Nottingham suggests that Earth's magnetic field may influence the rate of biological aging. Led by Professor Lisa Chakrabarti, the study utilized experiments on fruit flies to observe how magnetic shielding affects lifespan.

Researchers placed one group of fruit flies inside a magnetic shield made of a nickel-iron alloy to block nearly all of Earth's magnetic field. The study focused on two types of flies: healthy flies and those with a defective Pink1 gene, which causes mitochondrial dysfunction.

Results showed that flies with the defective Pink1 gene lived approximately 20 percent longer when protected from the magnetic field compared to those exposed to normal conditions. However, these flies also experienced a decrease in mobility and climbing ability. In healthy flies, no significant increase in lifespan was recorded, though those protected from the field showed improved climbing abilities. The findings suggest that the magnetic field's role in aging may depend on the condition of cellular mitochondria.
