AI JUST SPOTTED SOMETHING IN DNA THAT NO HUMAN SCIENTIST HAD EVER NOTICED. AND IT COULDN'T EVEN REPRODUCE ITS OWN DISCOVERY. 🤯
Anthropic set 950 Claude agents loose on 200,000+ reverse transcriptases. Task: find anything unusual. No human watching in real time.
21.5 hours in, one agent is reading raw DNA next to an enzyme nobody flagged as interesting before. It writes this, unprompted:
"[The DNA next to the RT] is spectacular: I can see by eye a tandem repeat array... that's a CRISPR-like... repeat array?!"
Then it does what a real scientist does. Counts the repeats. Measures the spacing. Compares it against every known system. Searches the literature for prior reports. Finds nothing. Files a report for human review.
Anthropic's lab confirms it. A real, previously undescribed enzyme system, found mainly in bacteriophages. They name it ART, array-associated reverse transcriptases.
Nobody knows what it does yet. Only a handful of similar systems exist, and every single one of them can cut, copy, and paste DNA. CRISPR is one of them. CRISPR is now the backbone of gene therapy.
Feng Zhang, the actual co-inventor of CRISPR, reviewed this and called it "genuinely intriguing."
Here's the part that should actually unsettle you. Anthropic reran the exact same search 10 more times. Zero reruns found it again.
An AI stumbled onto something possibly medicine-changing, once, and even its own creators can't make it happen twice on command.
Claude has discovered a previously unknown enzyme system hidden in the DNA of bacteriophages. Beside the enzyme’s gene sits a long array of repeating DNA—a structure that looks somewhat similar to CRISPR.
We don’t yet understand what this system does, but only a handful of known systems share its features, and all of them are able to cut, copy, and paste DNA. Historically, the discovery of such programmable systems has helped revolutionize medicine. CRISPR, for instance, is now the foundation of genetic medicines. But it will take much more work to learn what this system does, and whether it can be put to similar use.
