“Two genetically engineered farm animals reported today illustrate how far from Frankenstein’s stitched together monster animal biotechnology has come. One of those animals, a cow, secretes milk that lacks an allergy-inducing protein because researchers accurately blocked its production using the technique of RNA interference. And in pigs, scientists have used an enzyme called a TALEN to scramble a gene that would normally help remove cholesterol.”

The allergy-inducing protein causes diarrhea and vomiting in toddlers.

Of note to me because lately I’ve become interested in TALE nucleases.
