Anthropic’s AI finds a CRISPR-like gene-editing system in phages
The system, dubbed ART (array-associated reverse transcriptases), contains repeat DNA sequences resembling CRISPR, though it remains unclear if it can edit genes like CRISPR does. Anthropic’s technical report, not yet peer-reviewed, notes the discovery took 21.5 hours and involved narrowing down over 200,000 candidate proteins to a handful with unusual patterns.
Key points
- Anthropic’s **Claude** agents found a CRISPR-like system in **jumbo phages** after 21.5 hours of searching genomic databases
- ART contains repeat DNA sequences but lacks confirmed gene-editing utility; no peer review yet
- Scientists debate whether the discovery is novel or just a pattern-matching exercise by AI
Scientists are divided on its significance. Fyodor Urnov of UC Berkeley praised the transparency but called the work preliminary, while Le Cong of Stanford criticized the timing, saying experiments are still pending. Jason Gill of Texas A&M previously identified the reverse transcriptase in 2021 but noted Anthropic’s AI spotted related repeats, hinting at potential gene-editing activity. Anthropic’s CEO, Dario Amodei, speculated Claude might one day control lab equipment autonomously, but experts warn basic science to practical applications can take decades—like CRISPR’s 25-year journey from discovery to clinical use.
