Yes. On September 23, 2026, Anthropic reported that Claude agents autonomously identified a previously uncharacterized enzyme system in bacteriophages that the company calls array-associated reverse transcriptases (ART).
Anthropic said the system includes a reverse transcriptase, a partner gene, and a long array of evenly spaced DNA repeats reminiscent of CRISPR, though its primary function is still unknown. The company said roughly 950 agents spent about 21 hours searching DNA-sequence data before one flagged the unusual repeat pattern next to an odd-looking reverse transcriptase gene.
