Have you ever heard of a cow that is biologically incapable of getting mad cow disease? Not yet? Well, you're in luck today, 'cause that's exactly the news we're bringing you.

Yup, that's right. Scientists have proudly proclaimed that they have successfully produced the first cattle that won't have the disease, via genetic engineering. Eliminating from these engineered milk-factories is the protein prion, which is supposedly responsible for the fatal human ailment, and the variant Creutzfeld-Jakob disease.

But hold up. There's so much more they intend to do with this kind of technology. Maybe later on, they'll use similar techniques to engineer animals with more nutritious meats. But this will have to pass through a more stringent test from the Food and Drug Administration. Yeah, well, the yellow brick road was never always smooth.

However, until then, the spotlight remains with these altered cows. Immune for life. Now that's refreshing. Coming soon: birds incapable of transmitting bird flu?
