Earth’s magnetic field has a stronger impact on cellular health than realized, after magnetic shielding experiments increased the lifespan of flies, scientists say.
University of Nottingham researchers revealed their work in a recent paper published in Aging-US, describing a 20% lifespan increase when flies were protected from Earth’s magnetic field.
The work provides new evidence for how cellular energy production, performance, and lifespan are all influenced by the pull of Earth’s magnetic field. This could have major implications for how we understand aging and neurodegenerative diseases, as shielding can have mixed benefits and harms.
Mitochondria and Earth’s Magnetic Field
“Our interest is in the mitochondria, organelles which exist in the cells of all multicellular animals,” co-lead author Professor Lisa Chakrabarti told The Debrief. “Mitochondria produce the energy required in cells to drive everything that the organism needs to do.”
“We suspected that magnetic fields would affect the mechanism that mitochondria use to produce energy. This involves moving electrons around,” Professor Chakrabarti continued. “We live our entire lives within the Earth’s magnetic field. It passes through our bodies, our cells, and every living organism on the planet, yet we know surprisingly little about whether and how this invisible force affects the way our cells work.”
To explore this, the researchers studied the connection between our planet’s magnetic field and a gene called Pink1, using flies as subjects. The gene is associated with Parkinson’s disease in humans, a disease linked to mitochondrial problems.
“Research in this area is sparse, focusing mainly on how migrating animals sense magnetic fields, or on preparing humans for space travel,” said co-lead author Jacob Reed, a doctoral candidate. “Yet we still know very little about why all living organisms need or don’t need a magnetic field to function normally in the first place.”
Magnetic Shielding Experiments
Experiments involved observing four groups of flies. Using a specially developed magnetic shield, the team minimized the Earth’s magnetic field to almost zero for groups of flies both with and without the Pink1 gene. Both types of flies were also observed unshielded to provide a control for the experiments.
The effects were significant and varied. Shielded flies carrying the Pink1 gene showed a decline in physical performance but a 20% increase in lifespan, while shielded flies without the gene showed increased physical performance.
“We really expected to see some effect,” Professor Chakrabarti said. “The scale of the changes, e.g., a 20% increase in lifespan in the pink1 flies and also effects on climbing ability, were much greater than we anticipated.”
“Our results raise the intriguing possibility that the Earth’s magnetic field forms part of the biological environment to which life has adapted throughout evolution,” Professor Chakrabarti added. “Understanding how cells sense and respond to magnetic fields could ultimately reveal new ways of manipulating mitochondrial function in aging and disease.”
Earth’s Magnetic Field and Life
The team’s work opens new avenues for targeting mitochondrial problems with non-invasive procedures, offering potential solutions to medical problems.
“I think magnetic shielding treatments for people would need to be applied carefully since lifespan was extended, but climbing ability was adversely affected,” Professor Chakrabarti said. “However, shielded rooms exist, and it is possible that ‘doses’ of shielding could end up being applied by just remaining in those spaces.”
From here, the team is interested in exploring many facets of how Earth’s magnetic field affects life by exploring the timing of the shielding, dosage, and various types of organisms.
“We are most interested in cellular energy and how this pairs with [the] production of reactive oxygen species, for example. We are using quantum technologies to do this, and with our collaborators (Mather, Fromhold), we would like to develop this further,” Professor Chakrabarti says. “These parameters are all intertwined with the processes and differences between healthy ageing and various diseases of aging.”
“So really we have so many directions to go in,” Chakrabarti concluded.
The paper, “Hypomagnetic Fields Modulate Lifespan, Physical Ability and Mitochondrial Metabolism in a Pink1 model of Neurodegeneration,” appeared in Aging-US on September 23, 2026.
