To deter bioterrorism, U.S. imposes new rules on ordering synthetic DNA

https://www.science.org/content/article/deter-bioterrorism-u-s-imposes-new-rules-ordering-synthetic-dna
Why is everyone spooked by ai driven bioterrorism ? Like all of our water supplies are much easier to mess with compared to developing a virus or whatever that may or may not work
I'm curious if this is related to some things the top AI models are uncovering.

We know we don't get to see the bio side of the top models. They're out there solving hard maths problems etc but a query with the word 'microbes' in it often kicks you back to a smaller model automatically.

Are the bleeding edge models finding something scary enough that can be done with synthetic DNA that it needs to be restricted asap?

This might impact me and a small handful of other people who have messing around with microbes in their apartment as a hobby. We'll see what happens.

The device used to make oligonucleotides is pretty much an inkjet printer, from there it's cleverly applied enzymes to assemble the full strand. If you've got the skills and determination to get the synthetic DNA into a functioning cell, I don't think limiting access to synthetic DNA in the first place is going to stop you.

  But Esvelt points out the policy only requires screening for DNA sequences 50 base pairs or longer. A would-be bioterrorist, he argues, could easily stitch together a dangerous sequence from much smaller fragments ordered from multiple different suppliers. Esvelt says he has built an algorithm capable of screening sequences as short as 30 base pairs for their risk potential and made it freely available. “That’s the main flaw in an otherwise pretty great policy,” he says. “Don’t bother building a fence if there’s going to be an obvious huge gap in it.”
So, a song and dance of doing something that will most likely just inconvenience people doing real work.

Also, DNA chemistry is very well established. Someone with the appropriate background could easily assemble oligos without too much difficulty. I guess this stops Little Johnny from printing ebola from the internet.

> U.S. government–funded scientists who make and manipulate DNA sequences will face tougher regulations

Seems like this has little to do with deterring terrorism then, considering the assumption that a terrorist may not be a US government funded scientist.

Trouble is, that assumption hasn't always worked out in the past: https://en.wikipedia.org/wiki/Bruce_Edwards_Ivins

But yes, this is stupid. No one who is inclined to build a biological WMD is going to be more than mildly inconvenienced by supply restrictions. DNA isn't plutonium.

When DNA is outlawed only outlaws will have DNA.

> It’s great, because it does something instead of nothing

I am detecting a bit of frustration here.

Where is the disclaimer, that all labs are 100% safe, and it is not possible for something like virus to escape from lab?

This sounds unbelievable, but hey, we have AI. Let's just keep pretending this is the regular rate of tech advancement ...

Carry on, everything is apparently fine.
