AI Designed a Lethal Virus Never before seen in Nature. . . Now What?
K
22:34Kevin EsveltGUEST
So these were existing, an existing family.
K
22:37Kevin EsveltGUEST
They trained it on 15,000 different sequenced variants, just a few mutations to quite a few mutations, of this one virus that infects bacteria, Phi X174.
K
22:48Kevin EsveltGUEST
And then they had the AI spit out 300 designs for different mutated versions of that virus, and they tested them all, and 16 of them worked, which is an incredible success rate.
K
23:04Kevin EsveltGUEST
Now, doesn't necessarily mean that you can apply this to a human virus.
The AI Reckoning

And they worked with a very simple, well-understood template.
S
50:06speaker_0HOST
The Phi X 174 virus.
S
50:08speaker_1HOST
Right, which only has about 5,400 to 6,000 base pairs.

Professor Martha Clokey, a prominent voice in the field, pointed out in our sources that the current results are highly constrained because of this simplicity.

These AI systems were trained on large collections of genetic sequences and then used to generate entirely new versions of bacteriophages, viruses that attack bacteria.
J
0:49Joshua StarkHOST
Researchers focused on a well-studied phage called Phi-X174 that infects E. coli.
J
0:58Joshua StarkHOST
The AI generated thousands of potential genomes, and researchers selected hundreds for laboratory testing.
J
1:07Joshua StarkHOST
Sixteen of the synthetic phages proved to be viable and capable of infecting bacteria.

I found, I, I found that surprising, and they, they don't talk about it, and maybe, maybe it's not surprising, but, you know, they say the genomic start sequences of all the Microviridae sequences were highly diverse.
K
44:50Kathy SpindlerHOST
All the PhiX174-like-
V
44:52Vincent RacanielloHOST
Yeah
K
44:52Kathy SpindlerHOST
... genomes started with the same consensus nucleotides.
9 MINS LATER
V
54:10Vincent RacanielloHOST
One is the insertion of a new gene J in, in Evo63, extended non-coding regions, the loss of a gene, elongations of genes, swapping of genes.
V
54:22Vincent RacanielloHOST
But the origin of replication had no mutations again across all 16 genomes, so you really cannot change that at all.
V
54:34Vincent RacanielloHOST
And it, and at the phylogenetic level, these phages are similar to PhiX174-like microviridae, so that is what they wanted it to be.
V
54:44Vincent RacanielloHOST
Um, they, they then, uh, wanted to compare it to natural isolates of PhiX174, so they collected a bunch of data sets of natural PhiX-like viruses.

At the beginning of August, something pretty incredible happened.
L
2:01Laurel BristowHOST
Scientists published a paper detailing how they created new viruses using artificial intelligence.
S
2:07speaker_4SOUNDBITE_SPEAKER
Here's a new addition to the list of things AI can do.
S
2:10speaker_4SOUNDBITE_SPEAKER
Create new viruses not found in nature.
S
2:13speaker_5SOUNDBITE_SPEAKER
It does sound like something from a sci-fi movie, but this is real.
S
2:17speaker_5SOUNDBITE_SPEAKER
A U.S. team have used artificial intelligence to design completely new viruses.
S
2:23speaker_5SOUNDBITE_SPEAKER
The good news, they
S
2:23speaker_6SOUNDBITE_SPEAKER
say, the 16 new viruses created by AI pose no threat to humans.
