U.S. and Japanese scientists reported on Sunday that they had used genetic engineering to produce cattle that resist mad cow disease. Great! So instead of a simple solution to stopping mad cow like don't feed cattle (who are vegetarians) animal parts from sheep and other cows, let's complicate the whole thing by genetically engineering animals to "lack the nervous system prions, a type of protein, that cause BSE and other related diseases." Yum, now we can go back to feeding our cattle spinal cords from sick, old cows!
