UCSF scientists discover that the spindle, the structure that divides chromosomes equally during mitosis, actually gets stronger when it is stretched.

Every second, millions of cells in your body divide in two. In the space of an hour, they duplicate their DNA and grow a web of protein fibers around ...

To ensure our bodies function correctly, the cells that compose them must operate properly. Imagine a cell as a bustling city ...

Our window into the cellular world just got a whole lot clearer. By combining two imaging technologies, scientists can now watch in unprecedented 3-D detail as cancer cells crawl, spinal nerve ...

To observe living cells through a microscope, a sample is usually squeezed onto a glass slide. It then lies there calmly and the cells are observable. The disadvantage is that this limits how the ...

This video of a so-called HeLa cell dividing demonstrates how sensitive the cell division process is. While all is going well at the beginning of the video, as the clip nears its end you can see the ...

CAPTION: (Top) Condensins seem to act as a molecular crosslinkers to make loops. (Bottom, left) Condensins (red) locate around chromosome center. (Bottom, right) Nucleosomes around the periphery ...

Watching living cells in action isn't easy. Not only are they microscopic, but excessive light disrupts the cell division process. A new microscope allows a better glimpse into the microcosmos.
