Summary

Anthropic says nearly 950 Claude agents uncover a previously uncharacterized CRISPR-like enzyme system in bacteriophages after analyzing DNA data for 21 hours, though its function and practical uses remain unknown.

Key Points

  • Anthropic says Claude autonomously discovers a previously uncharacterized enzyme system in bacteriophages that it compares to CRISPR-like machinery.
  • Nearly 950 Claude agents search DNA-sequence data for 21 hours, processing 210 million tokens before identifying an unusual repeating pattern for human review.
  • Anthropic says it still does not know the enzyme system's function or whether it has practical applications, as it uses the result to attract scientists and expand into drug discovery.
