Scientists open new window into how cancers override cellular growth controls
Rapidly dividing cancer cells are skilled at patching up damage that would stop normal cells in their tracks, including wear and tear of telomeres, the protective caps at the end of each chromosome.

Seeing cancer in three dimensions
One of the hallmarks of cancer cells is that certain regions of their DNA tend to get duplicated many times, while others are deleted. Often those genetic alterations help the cells become more malignant — ...
