An AI agent found something interesting beside a gene scientists already knew about.
Anthropic's September 23 research report describes a search through DNA data for unusual reverse transcriptases, enzymes that copy RNA into DNA. The underlying enzyme wasn't new. What Claude noticed was its neighborhood: an array of repeating DNA sequences and a nearby partner gene whose function was unknown.
The search was much bigger than one clever answer in a chat window. Anthropic says roughly 950 agents spent 21 hours on it, using 210 million tokens. They gathered more than 200,000 enzymes from this family, identified 3,500 candidate systems, and narrowed the set to 20 for detailed reports.
One agent examined the odd repeating pattern, measured its spacing, compared it with known systems and searched the literature. Human scientists then investigated the candidate in the lab. The researchers call the system ART, for array-associated reverse transcriptases. It is found mainly in viruses that infect bacteria.
The repeats resemble the layout of CRISPR, but the team hasn't established what the system does. Early experiments found that the array produces distinct short RNA molecules. That is a lead for further research, not a demonstrated new gene-editing tool.
The detail that makes this story worth following is where the discovery began. The enzyme had appeared in earlier studies; the proposed new system emerged from looking around it. The agents supplied a pattern and a case for investigating it. The lab still has to establish its function.
