There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

Every time a eukaryotic cell divides, it faces a monumental challenge: It must carefully duplicate and divide its genetic ...

New research is advancing understanding of certain cancers and complex congenital disorders by illuminating how BRD4, a protein that scientists have studied for years, directs the spatial organization ...

After uncovering the structure of a protein that allows respiratory syncytial virus (RSV) to skirt the immune response in a 2017 study, a team of researchers at Washington University in St. Louis went ...

Humans aren’t the only targets for viruses. Like us, bacteria become infected by many types of viruses. In fact, across billions of years, bacteria and viruses have engaged in a non-stop evolutionary ...

An exchange of genetic material that occurred when ancient giant viruses infected ancient eukaryotic cells could have caused the nucleus of the eukaryotic cell -- its defining feature -- to form. A ...

The artificial cell nucleus (right) constructed using the purified DNA was morphologically very similar to the natural cell nucleus derived from an egg (left). A team led by Professor Kazuo Yamagata ...

Bone implants often fail to fully integrate with surrounding tissue, limiting their effectiveness in regeneration. A natural but often overlooked cellular process could hold the key to better outcomes ...

A new study challenges a popular scenario put forward to explain the arrival of the first eukaryotic organisms. In the beginning, there was boredom. Following the emergence of cellular life on earth, ...

Researchers from the University of Hong Kong have discovered that the Epstein-Barr virus (EBV), a common human virus closely linked to nasopharyngeal carcinoma (NPC), can change the 3D structure of ...
