Chinese scientists have made a fundamental breakthrough in the understanding of the nucleolus, a structure with important functions in the nucleus. Their findings may also pave the way for diagnoses ...

RNA, or ribonucleic acid, is a short-lived molecule copied from DNA that enables cells to use genetic information. Specific DNA sequences are copied into RNA, which then delivers these instructions to ...

Ribosomes carry out the cell’s most essential function—translating genetic information into proteins. But even though scientists understand much about how these protein generators are formed, their ...

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 ...

Biological reactions are strongly coupled to the structure and properties of their environment. Cellular compartmentalization into biomolecular condensates with distinct material properties enables a ...

Capital structure refers to the mix of funding sources a company uses to finance its assets and its operations. The sources typically can be bucketed into equity and debt. Using internally generated ...

Deep within the intricate world of cellular biology, scientists at Weill Cornell Medicine have made a remarkable discovery about aging that could transform our understanding of human longevity. Their ...

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 ...

Without a doubt, aging is a complex process. It’s a journey that each cell in the body undertakes. Along the way, aging can lead to the development of serious health conditions in humans such as ...

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 ...

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 ...

Silencing of ribosomal RNA genes (rDNA) requires binding of the chromatin remodelling complex NoRC to RNA that is complementary to the rDNA promoter. NoRC‐associated RNA (pRNA) folds into a conserved ...
