Like the one above. Yum.<\/p> So why use human genes to make gelatin?<\/p> Scientists are not actually on a mission to (a<\/strong>) gross us out, or (b<\/strong>) make us into cannibals. Gelatin<\/a>, summed up quickly, is usually made by boiling and chemically processing the bones, skin, and connective tissue of animals like cows and pigs to release collagen, a long molecule that, when further broken down by heat and mixed with water, will set into a gel at room temperature. This is where your jiggly dessert comes from (apologies if I’ve just turned you vegetarian, or at least non-gelat-tarian).<\/p> Unfortunately, this process yields ...<\/p> What’s the News: Several days ago, a tasty tidbit hit the science blogosphere: writing in a journal of the American Chemical Society, scientists reported the successful production of gelatin from human proteins.Understandably, the verdict of the crowd was, “Groooooosss!” The … Continue reading <\/a>
