About 950 Claude agents find an unknown enzyme system

TL;DR

• On 23 September Anthropic introduced a life sciences lab and its first result: Claude agents found a new enzyme system, array-associated reverse transcriptases (ART), in bacteriophages.
• The post gives roughly 950 agents, 21 hours and 210 million tokens; the preprint counts 949 sessions, 119 tasks and 215.6 million tokens over 21.5 hours.
• What ART does is still unknown. The lab has shown its repeat array is expressed as distinct short RNAs.
