New Scientist reports that researchers have created a line of mice that are completely immune to cancer. They hope studying both the genetics of these mice, and the method by which they fight the cancer, may someday have an impact on human cancer treatments. Especially because they seem to be immune to all forms of cancer, not just specific types.

As interesting to me is this story on stem cells via pathenogenesis, which basically makes it possible to replicate stem cells without requiring fertilization. If successful, this would be an effective way to end the debate over the ethics of stem cell research.
