tube” meat, a hamburger made from a cow's stem cells, will be produced this fall, Dutch scientist Mark Post told a major science conference Sunday. Post's aim is to invent an efficient way to produce skeletal muscle tissue in a laboratory that exactly mimics meat, and eventually replace the entire meat-animal industry. The ingredients for his first burger are “still in a laboratory phase,” he said, but by fall “we have committed ourselves to make a couple of thousand of small tissues, and then assemble them into a hamburger.” Post, chair of physiology at Maastricht University in the Netherlands, said his project is funded with 250,000 euros from an anonymous private investor motivated by “care for the environment, food for the world, and interest in life-transforming technologies.”
