Build Your Own Virus
Wire Tap writes "Scientists have assembled the first synthetic virus. The US researchers built the infectious agent from scratch using the genome sequence for polio. The most amusing part is this snippit: 'To construct the virus, the researchers say they followed a recipe they downloaded from the internet and used gene sequences from a mail-order supplier.' Heck, don't we all have our own mail-order suppliers for gene sequences?"
Ok, wtf, from the article we have these snippets:
Responding to criticisms that such research could lead to bioterrorists engineering new lethal viruses, the scientists behind the experiment said that only a few people had the knowledge to make it happen.
and then the rest of the article is filled with stuff like this?!
To construct the virus, the researchers say they followed a recipe they downloaded from the internet and used gene sequences from a mail-order supplier.
According to researcher Jeronimo Cello, the polio virus assembled in the laboratory is one of the simplest known viruses. "It was very easy to do," he said.
"We've known this could be done. We've known it was just a matter of time before it was done," he said.
Why shouldn't we be worried?
Have you hugged your Karma Whore today?
What if, say, a virus could be designed to destroy cancer cells?
Until they mutate and we have that same viruses destroying healthy tissue. Besides, what would the immune response be? Would that make you sick?

That these scientists downloaded their instructions off the net and used ordered the sequence mail order is not at all the shock that this story portrays it as. Virtually every common technique in molecular biology can be accomplished with a pre-made "kit" from one of several major vendors (e.g. Sigma, BioRad, Qiagen). These kits contain all the necessary reagents and instructions for completing the procedure. Most of the companies that produce these kits also post the instructions on their websites in case you loose the printed copy. Any trained molecular biologist would have a pretty easy time recreating the "kit" from the directions and the ingredient list.
As for getting DNA by mail, that's standard practice at most research labs I've been involved with. It's more expensive than producing it yourself, but a hell of a lot more convenient. Many universities even have their own, "in house", sequence generation facilities that labs interact with by, you guessed it, inter-departmental mail.
I'd say the poster of this story was taken by the shock value of these statements (and perhaps they are more shocking in our terrorist-paranoid times), but in reality, there's nothing to be suprised by.
I can understand that the virus was created from scratch in the sense they it didn't come from mammalian cell infected by another polio virus, but my guess is that it is not from scratch in the sense of making a biological thing out of stuff from a chemistry set, because the "reagents" used in the process almost certainly had biological origin in their manufacturing.
Can someone familiar with the process comment on the source of the reagents?
The problem is that you're thinking of it like a normal, natural virus. It's not. It's really just a hunk of DNA surrounded by a protein capsule. That's what a virus is too, but the difference is that a virus can use you as a host to replicate. This DNA in a capsule can't. It simply isn't able to. It could potentially gain that ability and become Just Another Virus, but then it's just that: another virus, not really any different than the ones that are out there already. No more lethal, no more dangerous, just with a different heritage.
The scenario that you're envisioning is no different than another piece of DNA gaining the ability to reproduce. Remember, this stuff gets integrated in to your genome when it's used, so it's really about as likely to gain reproductive ability as any other random part of your genome. And in case you've never dealt with the human genome, I'll tell you this: you've got a lot of it, but I don't see you worrying that a mutant p53 gene in someone's cancer will gain reproductive ability and go around infecting people and giving them tumors all over their bodies before spreading to the next victim. This is just as likely, and even more scary.

This is very true (you're thinking of influenza by the way) but the thing about the chicken strain is that it was able to reproduce in areas other than the upper respiratory tract, where the human influenza virus is stuck in. Mixing the human genes with the chicken ones allowed the new strain to reproduce in any human cell, which would have killed scores of people.
This is a very real danger, but how does this change anything related to the technology? With the old technology, you could have easily done this by hand, rather than synthesizing from scratch, you could shuffle a bunch of coinfected influenza viruses around until you got what you wanted, essentially speeding up the natural process. You could also modify the existing virus to do this.
Just like nature did in creating the Influenza strain you're talking about.
"I may not have morals, but I have standards."
Now it all looks like low level "programming". How long until there's enough research so that scientists can start using high level languages for this?
It may sound stupid, but that's also what some hackers though about C or anything 20 years ago. Or even now (compiled vs. interpreted).
