Under a microscope, a cell's cytoplasm can resemble a tiny underwater version of New York's Times Square: Thousands of proteins swarm through a cytoplasm's watery environment, coming together and breaking apart like a cytoskeletal ...

About 1.5 to 2 billion years ago, the great evolutionary 'big fish, little fish' engulfment occurred. Somehow, scientists think, one bacteria swallowed another, creating a new type of cell, the eukaryotes.

Normally, cells are highly active and dynamic: in their liquid interior, called the cytoplasm, countless metabolic processes occur in parallel, proteins and particles jiggle around wildly. If, however, those cells do not ...

Conventional wisdom holds that the cytoplasm of mammalian cells is a viscous fluid, with organelles and proteins suspended within it, jiggling against one another and drifting at random. However, a new biophysical study led ...

The contents of plant cells undergo continuous mixing by a process known as cytoplasmic streaming. Yet although this process was discovered more than 200 years ago, its exact purpose has remained unclear. Motoki Tominaga ...

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...
