Anthropic says Claude flagged a bacteriophage enzyme system

Anthropic says about 950 Claude agents flagged an uncharacterized bacteriophage enzyme system, ART, whose function is unknown; a CRISPR researcher calls the method routine.

Anthropic says nearly 950 Claude agents searched DNA databases for 21 hours and flagged a previously uncharacterized enzyme system, dubbed ART, found mostly in bacteriophages. The Verge reports the run processed about 210 million tokens, while The Decoder says the agents reviewed more than 200,000 reverse transcriptases and noted repeating DNA beside an unusual enzyme; those are different measures, not a stated contradiction on scale. Humans supplied the initial research question and performed the lab experiments, and both outlets say the system’s function and practical applications remain unclear even though Anthropic compared it to CRISPR machinery. Lucas Harrington, a CRISPR researcher and Mammoth Biosciences co-founder, said similar genome mining has existed for decades and that Anthropic has not shown what the system does. The company calls the finding the first result from its new 2026 Bay Area wet lab as it courts scientific and drug-discovery work ahead of a planned public listing.

• Anthropic compares the system to CRISPR machinery, but both reports say its function and any practical use remain unknown.
• Humans set the research question and ran lab validation; Lucas Harrington, a CRISPR researcher and Mammoth Biosciences co-founder, called the genome mining decades old and said Anthropic has not shown what the system does.
• Anthropic presents it as the first result from its 2026 Bay Area wet lab while courting scientists and drug-discovery work ahead of a planned public listing.
