It's meat that isn't taken from a slaughtered animal but rather produced by culturing "meat" cells (real animal cells). It's real meat, it just wasn't grown inside an animal so there's no suffering involved. Some people don't like the idea of eating something that "came from a lab" but I would think this is a good development. We can stop animal cruelty without force-feeding everyone a vegan diet against their will. It's also much easier on the ozone layer than animal-grown meat.

Unrelated: The China Study, I'm not a fan of it, though I'm sure it contains some nuggets of wisdom. My wife is very enthusiastic about it, but to me it's just too black and white. Real life doesn't work that way. The book comes across as a religious text the way it demonizes anything non-vegan. It makes me question the objectivity of the authors, and indeed the book does quote selectively from the literature. I'm sure (occasionally) eating vegan can be healthy, and I'm sure you shouldn't eat a pound of bacon every day, but I don't believe eating meat or dairy now and then will poison you. I prefer a balanced discussion instead of a holy text. Unfortunately balanced discussions are hard to find when it comes to diet.
