Anthropic's biology team published results on November 4, 2026, showing that Claude identified vault particles in bacteria and bacteriophage proteins and produced the first 3D structural model of a bacterial vault particle.
Vault particles, barrel-shaped protein structures first discovered by Leonard Rome and Nancy Kedersha in 1986, had previously been found only in complex organisms like animals and plants, with their biological function still unknown. Claude ran the wet-lab pipeline end-to-end, cutting particle isolation from three days to about 90 minutes and delivering a structural model in 34 hours rather than the weeks to months typical of manual methods, though the team noted Claude made simple mistakes that required collaboration with machine learning researchers.
