Anthropic’s Claude identifies novel enzyme system in 21-hour autonomous search

Key points

• Anthropic’s Claude model identified a novel enzyme system called array-associated reverse transcriptases (ART) in bacteriophages.
• The discovery was made autonomously by nearly 950 AI agents over 21 hours, using 210 million tokens, with minimal human input.
• The ART system shares structural similarities with CRISPR, but its function and practical applications remain unknown.
• Anthropic’s new life sciences laboratory, established in spring 2026, aims to accelerate biological discovery using AI.
• Experts are divided on the significance of the discovery, with some praising the AI’s capabilities and others questioning its practical value.

Background

Anthropic has been expanding its AI capabilities, including merging Claude Cowork into Claude Chat and developing its own next-generation model. The company has also introduced an invisible watermark to Claude-generated text to improve transparency. This announcement follows a trend of AI companies pursuing scientific research to demonstrate the value of their models.

How outlets are covering it

Anthropic and its CEO Dario Amodei emphasize the discovery as a breakthrough in AI-driven biological research, highlighting Claude’s ability to autonomously identify novel systems. Stanford bioengineering professor Stanley Qi praised the AI’s ability to detect unusual biological patterns. However, microbiologist Kevin Blake expressed skepticism, noting that CRISPR-like sequences are common and that the discovery may not have practical applications. The Conversation’s Dimitri Perrin highlighted the importance of AI’s autonomy in scientific research, while The Verge’s Robert Hart noted the announcement’s timing ahead of Anthropic’s public listing.

Why it matters

This discovery marks a potential shift in how AI can contribute to scientific research, particularly in biology. If AI can reliably identify novel systems, it could accelerate the discovery of new tools for gene editing and medicine. However, the practical applications of the ART system remain uncertain, and the announcement may also serve to attract scientists and investors ahead of Anthropic’s public listing.

What to watch

Anthropic will continue to investigate the function of the ART system and may expand its AI-driven research to other areas of biology. The company is also likely to use this discovery to attract more scientists and investors, potentially ahead of its public listing. Further experiments will be needed to determine the practical applications of the ART system.
