Deep within the nucleus of every cell lies a structure smaller than a pinpoint that may hold the secret to aging. Scientists at Weill Cornell Medicine have discovered that the nucleolus, long known ...

Biologists discovered that a scaffolding protein called TCOF1 is responsible for the formation of a biomolecular condensate called the fibrillar center, which forms within the cell nucleolus. Inside ...

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 ...

A team led by Princeton University researchers has developed a tool to peer inside the nucleolus, the cellular compartment responsible for the earliest steps in protein manufacture. This system opens ...

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 ...

In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by ...

Gear-obsessed editors choose every product we review. We may earn commission if you buy from a link. Why Trust Us? More than a decade of research shows that the nucleolus—the largest structure in the ...

The secret to cellular youth may depend on keeping the nucleolus -- a condensed structure inside the nucleus of a cell -- small, according to nvestigators. The findings were elucidated in yeast, a ...
