This is really weird
So you can't access the whole article without a subscription, but researchers are developing the ultimate mystery-meat. From the abstract:
At one lecture, he was seized by an idea: “Why can’t we grow meat outside of the body? Make it in a laboratory, as we make so many other things.” In-vitro meat can be made by placing a few cells in a nutrient mixture that helps them proliferate. As the cells begin to grow together, forming muscle tissue, they are attached to a biodegradable scaffold. There the tissue can be stretched and molded into food, which could, in theory, be sold, cooked, and consumed like any processed meat.
