These are confusing times we live in. Are vampires legitimate objects of sexual desire, or is wanting to make out with a 100-year-old man still weird? What are dolphins thinking about? And what will you be eating in ten years?

It’s overwhelming, isn’t it? But Science Buzz is here to help. Here are the answers to the preceding pressing questions, in order: Yes, because when have millions of teenagers ever been wrong?; depends on the 100-year-old man, and if he’s interested too; sex, hunting, and horrible combinations of the two; and lab-grown meat.

We’ve talked about “artificial” meat here on the Buzz before, because it’s so weird, sciencey and awesome, but that was four years ago, and some wild things have developed since then.

Just in time for Thanksgiving, scientists in the Netherlands have created artificial muscles… for eating! The articles I found about the announcement were, unfortunately, pretty vague, and I’m not sure exactly what this muscle mass is like. It’s not a huge challenge to get a bunch of muscle cells to reproduce outside of a living animal, but getting them grow into a real muscle (and recognizable meat, instead of a formless mass of cells) is more difficult. It’s a similar problem to growing new organs for transplant, and similar methods have been tested; researchers are experimenting with using a collagen “skeleton” of a muscle for muscle cells to grow on. I think that the researchers in the Nethelands may have done something like this, because they’ve grown pig cells into what they’re referring to as “soggy pork,” a substance like “wasted muscle.” Just getting the structure right, it seems, is not quite enough for having lab-grown meat (or “in vitro meat”) that tastes and feels like the real thing. The scientists still need to figure out a way to “exercise” the bodiless muscle, but they think that they’re close enough to a solution that they claim the artificial meat could be on sale within five years. But, then again, that’s what this guy said five years ago, and in the 1930s, Winston Churchill said we’d be growing meat outside of animals within 50 years, so what do they know? Maybe they’re onto something this time, though—a sausage company is backing the research, and it’s thought that the first real fake muscles will be pretty small, and best used in ground meat applications. Like sausages.

It’s an interesting idea, in vitro meat. Unlike cloned meat, which still comes from a living, cloned animal, in vitro meat would never come from a whole animal, so there would be no animal cruelty. The original cells could be taken via biopsy, too, leaving the animal unharmed. It’s also hoped that meat-growing processes could eventually be better for the environment, because they wouldn’t require land to live on, or for growing feed crops, or as much fuel to move around, and they wouldn’t constantly be farting and producing methane (A very potent greenhouse gas). And while scientists in laboratories are doing these early experiments, commercial scale operations would be more like yeast- or yogurt-producing facilities. Even PETA, ever looking for trouble in the oddest places seems to be ok with the idea of in vitro meat, because it doesn’t require animals to be hurt or killed.

But would you eat it? Are you more or less comfortable with meat that was grown in a vat than with meat grown in an animal’s body?
