Anthropic’s Claude AI identified a new biological system called ART in viral DNA. ART contains a reverse transcriptase enzyme, a partner gene, and a long DNA repeat array. Its architecture resembles CRISPR but its function remains unproven. Claude searched 200,000 sequences, flagged 3,500 candidates, and picked 20 for deeper study. One AI agent noticed the repeat pattern and proposed ART for human validation. Existing bioinformatics tools could have found ART but required manual direction. Claude operated with broad objectives and chose its own analyses. Human experiments confirmed the AI’s suggestion. Anthropic opened a new life sciences lab for such work. Future AI may autonomously control lab equipment for experiments.
What changed
Researchers manually searched sequences and selected candidates for analysis.
What it unlocks
AI agents can now autonomously search datasets, generate hypotheses, and prioritize candidates for experimental validation.
- 200,000 reverse transcriptases searched
- 3,500 candidate systems identified
- 20 systems selected for detailed analysis
