Science Education: Cell Biology
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?

Cellular ‘Cruise Control’ Systems Let Cells Sense and Adapt to Changing Demands
Molecular “cruise control” systems help cells sense and respond to the demands being placed on them during critical life processes.
Surprising Role for Protein Involved in Cell Death
A protein known for removing cellular corpses also appears to repair certain injured cells, keeping them from degenerating.
5 Reasons Biologists Love Math
To mark Pi Day (March 14), our scientific experts offer a few reasons math is important to biomedical research.
Chemist Marc Zimmer studies protein molecules that make animals glow in the dark—and help scientists study their cells.
Mastering Stem Cells
Researcher Peggy Goodell pursues the properties and uses of stem cells.
The Forces That Bind

Cool Video: How a Microtubule Builds and Deconstructs
In a process critical for many biological activities, tubulin proteins snap into place to build a microtubule, part of the cell's skeleton, which then falls to pieces from its top end.
Cool Video: How Bee Venom Toxin Kills Cells
A new video that shows how a toxin destroys an animal or bacterial cell might help scientists design new drugs to combat bacterial infections.
Cool Video: How Cilia Do the Wave
Thin, hairlike biological structures called cilia are tiny but mighty. Working together, cilia play essential roles in human health, such as sweeping debris from the lungs.
Unprecedented Views of HIV
Visualizations can give scientists unprecedented views of complex biological processes. Here's a look at two new ones that shed light on how HIV enters host cells.
Cool Image: Of Surfaces and Stem Cells
The green threads shown here are neurons that have just formed from unspecialized cells called stem cells.
Cool Image: Training Cells to Devour Dying Neighbors
A healthy cell has engulfed a number of dying cells just as a predator might ingest wounded or dying prey.
