Basically, if the scientists are right, any species that might be vulnerable to microbes and infections could be totally helpless against a mirror cell. So plants get lots of infections. Lots of bacteria get into them. And they have all sorts of sophisticated ways of fending harmful bacteria so that they can grow and survive and give us food.

And that all falls apart if you're dealing with a mirror cell, as far as plant biologists can tell, because the plant defense systems are all tuned to life on our side of the mirror.

So as of now, scientists have figured out how to make some mirror proteins. They have been able to make a mirror enzyme that can build some mirror RNA. And of course, cells are made of a vast number of parts. And so it's a long way to go before anyone is going to put a mirror cell together.

Scientists are creating very simplified versions of cells from synthetic parts. And so these have a membrane. They have an inside and outside. You can put some molecules inside of them. Those molecules may do some of the things that happen inside of our own cells. These are not full-blown cells, however. So just how far you have to go to actually boot up a cell is just a fundamental question.

But there is a whole community of scientists who are going towards this goal. They sometimes call themselves the build a cell group. And they're headed in this direction. And, you know, they keep steadily making more progress. And so while no one is about to make a cell from scratch today, I don't think you can be assured that they won't be able to do it in 20 years.

I think that this is actually unprecedented. In the 1970s, scientists invented recombinant DNA where they could take pieces of DNA and insert them into the genes of bacteria. And they were already starting to publish results on this where you could get bacteria to make human proteins. And then a group of scientists said, whoa, whoa, let's stop and think about this and what we're doing.

But, you know, by then the technology had been created. More recently, people have heard of CRISPR, which is a way to actually edit DNA and And there again, scientists did get together and meet and have been talking about the ethics of this. But really, they only started talking about it after they had created the technology.
