The devil's defences
In this film scientists describe how the immune system works and how it can go wrong in cancer. In Tasmanian devils affected by a transmissible cancer the body's natural immune system is unable to detect the cancer.
This video is from 'Saving the Devil' -- a multimedia resource that tells the story of the Tasmanian devil and how science, in particular genomics, is playing a role in trying to save the species from extinction.
