Key points from article :
Nucleolus is in the center of the cell's nucleus.
It is where the cell’s protein-making machines — the ribosomes — are made.
Size of the nucleolus can determine the rate that a cell ages.
Organisms with smaller nucleoli tend to live longer.
NCL-1 — a gene linked to nucleolus regulation — may play a role.
Accelerated aging diseases have bigger nucleoli and more ribosomes.
Can’t say for sure yet whether the link is cause-and-effect.
The study was published in Nature Cell Biology journal.
