Recent studies have found a way to maintain youth and longevity, and the answer many have been searching for lies in bodily cells. The countdown to aging starts when an individual is born and is something that cannot be stopped, but it can be slowed. People search for methods to appear more youthful, such as surgeries and anti-aging cosmetic brands, and some have even gone as far as searching for the fountain of youth, often neglecting to look within their own bodies.
Revealing the microscopic sphere located deep within our bodies
Without being able to see the countdown, everyone experiences the effects of it, such as mobility decreasing, joint pains, grey hair starting to sprout, and the fading sharpness of senses. Over many decades, people have tried to find ways to avoid this decline through means of home remedies, and in this century, artificial surgeries are being normalized. This decline is more commonly known as aging.
The human body is designed to shut down eventually, and the clock starts ticking the second an individual is delivered into the world. Researchers have been trying to locate the biological core of mortality by looking at the protective caps at the end of chromosomes and mitochondria, but there was always something missing.
What is in cells that causes the countdown?
The answer was hiding in plain sight, which was the small sphere located within almost every cell in the human body, called the nucleolus. This part of the cell is responsible for cell regulation, producing ribosomes, stress response, and organizing the genetic material within a cell. However, the nucleolus has a limit, whereby if the limit is reached, it causes a reaction that leads to the irreversible decline of a cell.
When an individual is conceived, they are developed by the cells that contain this important organelle, the nucleolus, found in the nucleus. For the majority of a human being’s lifespan, it works discreetly, not serving as a problem, but it is the reason for aging later in life.
Ribosomal DNA instability: when a guarded space breaks and the genome starts to collapse
For the longest time, scientists just thought of the nucleolus as a place of production for ribosomes, but now it has been unveiled to be the biological timer itself. Weill Cornell Medicine research stated that the size of the nucleolus tells the amount of time it has left. This means that when the nucleolus structure is small, it symbolizes stability and youth; however, this does not mean it grows gradually, it actually remains small, and when it grows, it passes the limit of its size.
When the nucleolus passes the limit in size, it becomes weak and leaks, losing its ability to regulate cell division and produce ribosomes. These ribosomes are not supposed to leak; this destroys the genome, causing the DNA to be unstable and unable to repair itself due to its damage.
Can structural intervention stabilize the nucleolus to stop aging?
This discovery places old age in a new light, not as a spontaneous deterioration but as a formulated degradation that is triggered by the increase in the nucleolus’s size. A huge factor that contributes to nucleolus’s progression relates to calorie intake; low calorie intake, according to research, elongates life span in several species. How it works is clear: starvation keeps the nucleolus small.
This does not mean people should starve themselves to stay young, as science has found a way to mimic this outcome by physically anchoring the nucleolus to the membrane, prolonging cellular life without causing starvation. This discovery has revealed a pattern in the human body. At this point in time, scientists cannot stop the countdown in humans; they are closer than ever to understanding how to pause or stop aging entirely one day. Another advance in a different field of health making waves is artificial blood with amazing life-saving potential.
