How 950 Claude agents found a new DNA-editing system
What Anthropic's agents discovered, the catch, and how Opus 5.5 found it again.
The short version
On September 23, 2026, Anthropic announced that its Claude agents found a previously uncharacterized enzyme system in the DNA of bacteriophages, the viruses that infect bacteria. They named it ART, for array-associated reverse transcriptases. It sits next to a long array of evenly spaced DNA repeats, a layout that looks like a CRISPR array. Nobody knows what it does yet.
What makes it useful for us is the setup. Every agent in the campaign was an instance of Claude Code. The scientists wrote one research brief, and the agents ran the whole search with no human stepping in until the reports came out. The pattern works for any research job where you have too much data to read yourself.
