Claude Discovers Novel Enzyme System

Anthropic says its new life sciences lab pointed Claude at public DNA databases with only high-level direction from scientists, and the agent surfaced a previously unnoticed enzyme system inside a jumbo phage. The system carries CRISPR-like repeated DNA sequences, the same structural signature that made the original CRISPR discovery so consequential for gene editing. Feng Zhang, one of the scientists behind CRISPR gene editing, described the finding as genuinely intriguing, which is outside validation from someone with no reason to flatter a model. The important shift is in who does the searching. Until now most published AI biology work has used models to assist analysis that humans framed step by step. Here the agent chose where to look and what counted as interesting. A single finding does not establish a reliable discovery process, and the lab has not yet shown what the enzyme system does. Teams running research agents should still take note: a broad goal plus database access produced a result that domain experts found worth pursuing.
