Anthropic says Claude found a phage enzyme system whose job is unknown
The company calls it the first result from its molecular biology lab; the post offers a candidate discovery, not a demonstrated biological function.

Why it matters
Anthropic is moving Claude's biology work from literature and data analysis toward a lab that can test hypotheses. The phage finding is an early lead, while its unknown function makes clear that a model-generated candidate is not yet a validated discovery.

Anthropic says Claude identified a previously unknown enzyme system in bacteriophage DNA, with a nearby array of repeating DNA that the company says resembles CRISPR. Anthropic described the finding as the first result from its new molecular biology lab in a two-post thread on X on September 23rd. The system's function is still unknown, the company said.…
