Claude agents discover a new virus enzymatic system

The whole point is that the conclusion was verified experimentally. It was not just a textual output. And, the AI did not give the final answer. It gave a candidate and then, the scientists verified this in the lab. Agents were given a task to search through DNA libraries. There were 950 agents looking at more than 200,000 reverse-transcriptase enzymes. They narrowed the selection to 3,500 candidates. These are candidates for some unknown mechanism. Then, the top 20 candidates were verified by hand in the lab. Thus, the ART enzyme was discovered in bacteriophages (viruses that attack bacteria). It consists of a repeated sequence of the same DNA bases. It is very similar to the CRISPR mechanism. And, it generates small pieces of RNA. Hence, it is probably programmable as well.

Claude agents were put to work in a new Anthropic biology lab. Their first task was to search DNA databases. During 21 hours, 950 agents analyzed more than 200,000 reverse transcriptase enzymes. They selected 3,500 candidates for an unknown mechanism. After that, the top 20 candidates were verified by hand in the lab. This way, Anthropic researchers discovered the ART enzyme in bacteriophages. It is similar to the CRISPR mechanism but consists of a repeated sequence of the same DNA bases. It generates small pieces of RNA. Probably, it is also programmable.

The point is that Claude agents found a needle in a haystack but they did not replace a scientist who would verify the outcome.
