The size of a cell's nucleolus may reveal how long that cell, or even the organism it belongs to, will live. Over the past few years, researchers have been piecing together an unexpected link between ...

Knowing when you’re going to die is a fact best left unexplored. But for better or for worse, scientists have discovered a part of human cells that is tightly linked to the aging process, and it may ...

The secret to cellular youth may depend on keeping the nucleolus—a condensed structure inside the nucleus of a cell—small, according to Weill Cornell Medicine investigators. The findings were ...

The nucleolus—a conspicuous but obscure organelle within the cell nucleus—is normally too compact to be studied in detail. Researchers at Case Western Reserve University just learned how to simplify ...

Proteins are the infinitely varied chemicals that make cells work, and science has a pretty good idea how they are made. But a critical aspect underlying the machinery of protein manufacture has long ...

New research has advanced understanding of how the nucleolus is assembled through a process called liquid-liquid phase separation and has identified a protein that plays key role Researchers have ...

This model of the nucleus with nucleolus (pink) shows how ribosomal DNA is correctly repaired in young cells. In old cells with enlarged nucleolus, however, DNA repair is inaccurate leading to faster ...

Although known since the 1830s as a round, dark spot in a cell's nucleus, only recently has the nucleolus gotten its full due. Scientists have learned that besides building a cell's protein factories, ...
