Okay, get ready for this.  Your cat's poop could contain a cure for cancer!  Scientists have latched on to a parasite called Toxoplasma gondii, which is common in cat feces.  And they're digging into it - carefully, we hope - for the development of a cancer vaccine.

A group of Dartmouth College researchers are studying what the bug can do.  And they're upbeat about how other cells are created in response to it. They've tested it on mice, and it seems to work.

The key is that they've created a mutant form of the parasite, Toxoplasma gondii, called cps and that seems to be the magic bullet. One of the researchers compares the action of the cps to locomotion.  He says, "Aggressive cancers too often seem like fast moving train wrecks. Cps is the microscopic, but super strong, hero that catches the wayward trains, halts their progression and shrinks them until they disappear."
