Cells

Understanding the structure and function of cells and their many parts, in health and in disease—that's cell biology. Studies in cell biology focus on questions like:

How do cells move, communicate, divide, and ultimately die?
How are cellular components made and maintained?
What tools do we need to study cells up close and in real time?

Follow the links below to learn more about cell biology, including recent developments, and read profiles of researchers working in this field.

The Changing Needs of a Cell: No Membrane? No Problem!
While the vast majority of organelles in a cell are insulated by membranes, scientists are finding more and more membrane-less organelles that form as liquid droplets nested inside of each other.
Viruses: Manufacturing Tycoons?
Scientists observed a replicating virus storing copies of its DNA inside a compartment the virus built inside a host bacterium, providing possible evidence for how nucleus-containing eukaryotic cells evolved.
