Anthropic says Claude discovered an unknown enzyme system hidden in phage DNA
nptacek · x · 2026-09-24
Anthropic announced that Claude has discovered a previously unknown enzyme system hidden in bacteriophage DNA. Next to the enzyme's gene sits a long array of repeating DNA — a structure resembling CRISPR.
- Its function is unknown, but the handful of known systems sharing its features can all cut, copy, and paste DNA.
- Historically, such programmable systems have revolutionized medicine — CRISPR is now the foundation of genetic medicines.
- Anthropic cautions that much more work is needed to understand the system and whether it can be put to similar use.
Commenters framed it as AI moving beyond reshaping interfaces to probing the primitive machinery of life itself.
