Summary Report
About 950 Claude agents searching a DNA database found ART, an enzyme system in viral DNA with a CRISPR-like repeat array, whose function is still being investigated.
- 01. 950 agents, 21 hours and 210 million tokens narrowed 200,000 reverse transcriptases to 20 candidates; one flagged a CRISPR-like repeat array
- 02. Anthropic's lab confirmed the array is expressed as short RNAs; every similar known system can cut, copy or paste DNA, but ART's function is unknown
Anthropic says Claude has discovered a previously unknown enzyme system in the DNA of bacteriophages. Given one broad prompt to search a massive sequence database for interesting reverse transcriptases, about 950 Claude agents ran for 21 hours on 210 million tokens, narrowed 200,000 candidates to 20, and flagged a long array of evenly spaced DNA repeats beside an odd-looking enzyme, a layout resembling a CRISPR array. Anthropic calls it ART, array-associated reverse transcriptases, and its new lab confirmed the array is expressed as short RNAs. Its function is not yet known.
