I can't imagine why this isn't the biggest news story of the day week year:

White Blood Cells From Cancer-resistant Mice Cure Cancers In Ordinary Mice

White blood cells from a strain of cancer-resistant mice cured advanced cancers in ordinary laboratory mice, researchers at Wake Forest University School of Medicine reported today.

"Even highly aggressive forms of malignancy with extremely large tumors were eradicated," Zheng Cui, M.D., Ph.D., and colleagues reported in this week's on-line edition of Proceedings of the National Academy of Sciences.

The transplanted white blood cells not only killed existing cancers, but also protected normal mice from what should have been lethal doses of highly aggressive new cancers.

The only downside here is that the scientists don't yet know quite how this one very special mouse's blood does what it does. That will be key in figuring out how (or whether) this breakthrough can be applied a little closer to home.
