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 ...

A new kind of microscope is giving scientists a way to watch life inside cells with a clarity that feels almost unfair. Instead of choosing between seeing big structures or tiny particles, researchers ...

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

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 ...

Researchers have discovered how proteins work in tandem to regulate 'treadmilling', a mechanism used by the network of microtubules inside cells to ensure proper cell division. Researchers at the ...

Researchers have found a molecular mechanism that prevents multiplication of potentially dangerous cells by measuring the duration of mitosis. They have shown that this mechanism -- the Mitotic ...
