    When viruses invade, the immune system typically adopts a slash-and-burn policy, rounding up viral particles and destroying infected cells.

  • 26 Apr 1999

    Ionizing radiation can do scary things to a cell's nucleus, shuffling or deleting large chunks of DNA in ways that can turn cells cancerous. Radiation that misses the nucleus and hits only the cell's cytoplasm, however, has seemed harmless.
