Science Education: Cell Biology

A scanning electron microscope picture of a nerve ending. Credit:Tina Carvalho, University of Hawaii at Manoa.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?

Science Highlights

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.

The Drama of Cell Death
The fruit fly spermatid, arranged here to look like a bursting firework, can serve as a model system for studying apoptosis, or cell death.
