Khaberni - A recent scientific study published in the American journal "Cell" has revealed a radical shift in our understanding of aging.
The research conducted at the Salk Institute and Harvard University shows that brain aging is not just “fatigue” in the cells, but is caused by the body losing control over how to turn genes on and off; this leads to a state of chemical chaos inside the head.
Loss of control keys within the cells
The brain operates with a precise system akin to a massive electrical keyboard, where tiny chemical markers tell each gene when to function and when to stop, according to "Live Science".
Scientists explain that aging gradually erases these markers, causing the genes to operate randomly and uncontrollably, which is akin to an “electrical short” that disrupts the brain’s fundamental functions.
Rebellious genes attack the nervous system
Researchers have observed a strange phenomenon in the brains of aged mice, where “jumping genes” that were silent and controlled in youth begin to activate.
These genes start moving and replicating themselves within the genetic code, causing massive chaos that triggers the immune system; it then begins attacking and mistakenly killing brain cells instead of protecting them, which explains the deterioration in memory and cognitive abilities.
The puzzle of "super-agers" and control power
The results reveal a fascinating contradiction in our bodies; while the body tries to defend itself against rebellious genes, it ends up destroying its delicate neural tissue.
Experts suggest that individuals who maintain an ironclad memory at an advanced age, known as "super-agers," may owe their secret to having cells that succeed in keeping those jumping genes under complete control for a longer period than others.
