Overview
- Anthropic published a preprint reporting that on Wednesday its Claude model flagged a previously uncharacterized system called ART that pairs a reverse transcriptase, a partner gene, and a long array of evenly spaced DNA repeats.
- ART stands for array-associated reverse transcriptases and the repeat array resembles the guide-repeat architecture seen in CRISPR systems that can be made programmable.
- Anthropic says roughly 950 Claude agents ran for about 21 hours and processed about 210 million tokens to winnow hundreds of thousands of reverse transcriptases to a short list of candidates.
- Company researchers report human-run wet-lab tests in their Bay Area facility under BSL-1 and BSL-2 conditions found the repeats produce distinct short RNAs but have not determined the system’s biological function or programmability.
- The result has drawn cautious interest from outside scientists, Anthropic acknowledged prior related work and a separate Stanford team reported a comparable system, and the main open tasks are peer review, independent replication, and further functional experiments.
