gist
Anthropic reports that Claude agents found a new enzyme system: a reverse transcriptase beside a CRISPR-like DNA repeat array of unknown function. Scientists gave only high-level direction; agents mined genomes and triaged hits, then humans ran lab follow-up. Feng Zhang called the RT-linked RNA-repeat arrays intriguing and worth study, framing early agent-led biological discovery.
ideas
- Agents can surface uncharacterized biology. Claude spotted a reverse transcriptase next to a DNA repeat array that prior work had not treated as a system.
- Human direction stayed high-level. Scientists set goals and ran lab validation; agents did the large-scale sequence search and hypothesis triage.
- The function is still open. Anthropic publishes the finding before the system’s role is known, inviting follow-on characterization.
- External experts treat it as a real lead. Feng Zhang highlights the RT-linked RNA-repeat arrays as genuinely interesting and worth investigation.
- The lab is built for agent-plus-bench loops. Anthropic pairs computational mining with in-house experiments rather than stopping at bioinformatics reports.
