A eukaryote is any cell or organism that possesses a clearly defined nucleus. Eukaryotic cells form the foundation of complex, multicellular life, including apple trees, mushrooms, fish and humans.

While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions (Figure 1). In prokaryotic cells, DNA bundles together in a region called the nucleoid. Primitive ...

A newly identified virus–cell hybrid structure allows viruses to spread faster and more aggressively by hitching a ride on ...

Ryan Notti (left) and Thomas Walz (right) discovered new characteristics of a T cell receptor that are essential to a variety of cutting-edge T cell ...

Some of the body's cells stay put for life, while others are free to roam. To move, these migratory cells rely on ...

Scientists have discovered a mysterious new structure lurking inside every human cell. These tiny structures, dubbed hemifusomes, are just 200 to 400 nanometres in diameter. To put that into ...

Researchers think a microbe that was engulfed by an algal cell 100 million years ago has since evolved into an integral part of the cell's machinery. When you purchase through links on our site, we ...

Myelodysplastic syndrome (MDS) arises from defective blood stem cells that progressively lose their normal functions. Japanese researchers have revealed how changes in chromatin accessibility—how DNA ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Scientist Kate Adamala doesn’t remember exactly when she realized her lab at the University of Minnesota was working on something potentially dangerous — so dangerous in fact that some researchers ...
