Scientists may have found a surprisingly specific weak point in the aging process. A new study suggests that a molecule inside our cells helps keep mitochondria working properly, and its decline with age may contribute to cellular deterioration..@@@@
Even more striking, researchers were able to restore younger-looking mitochondrial function in laboratory worms by supplying either choline or phosphatidylcholine. The finding does not prove that humans can reverse aging, but it gives scientists a new biological pathway to investigate.
Our Cells May Lose Their Energy Flexibility With Age
Most human cells contain mitochondria, tiny structures responsible for transforming food and oxygen into chemical energy. They are often described as the “powerhouses of the cell,” but their role is more complicated than simply producing energy. Healthy mitochondria also need to adjust their structure and activity as the body’s energy demands change.
