Great posts, but is anyone else annoyed at how "Science" is always presented as some sort of anthropomorphized entity in the press?

mcgraw: These simple cells do not have DNA, so how could they have a genetic barcode?

Otherwise, intresting fist link.

Ah, what a great time to be a biochemist. I've heard about the Harvard group before but not about the barcode project. It's interesting that they've chosen a mitochondrial gene as their target sincemitochondria were once free-living organisms and have their own set of DNA distinct from an organism's genomic DNA. I think I'll keep an eye on this project.

This is one of the coolest posts I've seen in a while! :)

(just kidding, delmoi. good point.)

But the simple cells do have DNA...that's the point of the article. Nucleic acids are DNA and RNA. This group is suggesting that liposomes containing self-replicating nucleic acids will expand and steal lipids from the liposomes that don't contain nucleic acids.

You're right about the barcode part though. The simple cells do not have mitochondrial DNA, and so won't have a barcode but that wasn't the point of the first article.

This applies to more than lab creations.
You don't suppose Google is on to this?

“What we showed was that you can get a Darwinian competition to emerge just from the basic physical properties of the system,” says Irene Chen, a graduate student in Szostak’s lab. “It doesn’t require biological machinery.”

I hope there will be metadata! Mm-mmm!

Still waiting for a registration-based link, mcgraw.

Sure, that's fine, but it was a little cooler when they actually wrote the barcodes in.

OK, here's the frustrating registration-based link of the week. I'd like to read this article about the universe verse verse:
