## Summary

Anthropic reports the first 3D structure of a vault particle found in prokaryotic cells, built from 96 copies of a single phage protein called L05. The team says Claude helped search sequence databases, optimize a purification method that cut vault isolation from about three days to 90 minutes, and process cryo-EM data into a first model in 34 hours. The function of vaults remains unknown, and the preprint has been submitted to bioRxiv.

## Why it matters

The post shows how Claude was used across literature search, lab protocol optimization, and cryo-EM processing, with specific time savings reported.
