About 950 agents examined more than 200,000 reverse transcriptases and narrowed 3,500 candidates to twenty systems; the lab confirmed short-RNA expression from the ART array.
Anthropic tasked a multi-agent system with searching genomic databases for unusual reverse transcriptases. Over 21 hours, roughly 950 agents collected more than 200,000 sequences, identified 3,500 candidate systems and produced twenty priority reports.
One candidate combined a reverse transcriptase, a partner gene and a long repeat array in bacteriophage DNA. Researchers named it array-associated reverse transcriptases, or ART; early experiments indicate that the array is expressed as distinct short RNAs.
The discovery is not a new CRISPR. ART’s function is unknown, validation is early and the work is not yet peer-reviewed. The stronger finding concerns the workflow: AI narrowed the search space and generated a hypothesis that human scientists then took into the lab.
It is a concrete AI → biological hypothesis → selection → wet-lab cycle, with potential relevance to bioactive and mechanism-of-action screening.
A preliminary Anthropic result released as a preprint. ART’s biological function remains unknown and gene-editing activity has not been demonstrated.
