Claude reportedly identifies ART, a CRISPR-like enzyme system whose function remains unknown

A post describing Anthropic's announcement says Claude identified ART, short for array-associated reverse transcriptases, a new enzyme system resembling CRISPR. The account describes about 950 agents using 210 million tokens over 21 hours to narrow 200,000-plus reverse transcriptases to 20 candidates for wet-lab validation in the Bay Area. The post stresses that ART's function remains undetermined. Humans performed all biosafety level 1 and 2 experiments, while Claude searched for anomalies and wrote reports, according to the account.
