Researchers at Anthropic have determined the three-dimensional structure of a previously uncharacterized vault-like protein particle produced in bacteria. Claude assisted with protein searches, experimental design, purification, and electron-microscopy analysis. The discovery may illuminate the evolutionary origins and still-mysterious functions of cellular vaults ...Read more

Researchers introduce Strategist, an AI system that develops, tests, and reuses reasoning procedures across tasks. On thirty benchmarks, it reportedly outperforms the strongest baseline on twenty-four, achieving comparable average accuracy at 39 percent lower inference cost. Independent replication remains to be established ...Read more
