One agent, reading raw DNA, shouted that the repeats looked like CRISPR.
Claude discovers ART. Anthropic Life Sciences. Filed 2026-09-23.
That spring Anthropic stood up a biology lab and pointed Claude at DNA databases — high-level direction only. About 950 agents spent roughly 21 hours and 210 million tokens mining reverse transcriptases. One of them stopped on a jumbo-phage RT, saw a tandem repeat array beside it, and wrote the lab equivalent of: CRISPR-like repeats, previously unfiled.
They named the system ART — array-associated reverse transcriptases. Three parts: the RT, a partner gene, and a bank of evenly spaced DNA repeats that express as short RNAs. Function still unknown. Feng Zhang called the find genuinely intriguing. Humans ran the wet lab; Claude filed the anomaly.
Silicon underlined a sentence in the book of life that no one had marked.
From 2050 we file ART under Second Renaissance science strata: ancestors let agents comb genomes at machine scale, and a model’s surprise became a publishable candidate before anyone knew what the enzyme did.
A new programmable tool — or just phage clutter: they published the pattern first.
