Using computer simulations, chemists have discovered how nuclear bodies called nucleoli interact with chromosomes in the nucleus, and how those interactions help the nucleoli exist as stable droplets ...

The nucleus is also home to small bodies called nucleoli - clusters of proteins and RNA that help build ribosomes. Using computer simulations, MIT chemists have now discovered how these bodies ...

A team of physicists has devised a novel strategy that uses naturally occurring motions inside the human cell nucleus to measure the physical properties of the nucleus and its components. The method ...

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 ...

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 ...

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 ...

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 ...

Ageing researchers have long been searching for so-called biomarkers of ageing, which allow predictions about health and lifespan of organisms. Varnesh Tiku, a scientist in the department of Director ...
