Uh-Oh: Cows Genetically Modified With People DNA To Produce More Human-like Milk
Don't 'moo' at me like you're some sort of classy heifer -- you've got shit on your leg!
Because there's less than zero regulations for genetic manipulation in China (make me a superhero already, God), a team of researchers there have spliced human DNA into cow embryos so, when older, they produce milk much more similar in nutrition to that of humans. Yeaaaaaaaaaah (rich, chocolatey Ovaltine FTW).
The reason that Chinese researchers have introduced human genes into cows is to enable them to produce an adequate substitute for human breast milk, since baby formula doesn't offer the same benefits. That said, there's no reason you couldn't drink it, and according to the researchers, "the milk tastes stronger than normal milk," whatever that means.
To get the human bits into the cows, Holstein dairy cow embryos had their DNA modified using cloning techniques. The clones were implanted into surrogates, and so far about 300 of these "humanized" cows have been created. Their milk boasts a much higher nutritional content, 20% more fat, and a variety of proteins that boost immune systems in human babies.
Hey, I'm all for a better substitute for human breast milk than formula (E = mc2), but splicing human DNA into cows to produce it? I'm not sure how I feel about that. *contemplating* Call me when it makes their udders look like tits and we'll talk.
Thanks to Kirk, who got to milk a cow on a school field trip once.
