Claude identified repeated DNA sequences next to a phage gene, which the team named ART; the system resembles CRISPR in structure but its function is unknown.

About 950 Claude agents ran for 21 hours and screened over 200,000 reverse transcriptases to find a new system, which Feng Zhang called a good example of AI participating in biological discovery.

Anthropic's bio lab published its first results: about 950 Claude agents ran for 21 hours and screened DNA databases down to 3,500 new candidate reverse transcriptase systems, named ART.

Claude identified a hidden repeat pattern in raw phage DNA and found a previously unknown enzyme system with CRISPR-like repeats nearby, per a Chinese post.

Claude read literature and genome data to form a hypothesis, and researchers validated a previously unknown enzyme system in the lab.

Opus 5.5 scores 66 on the Artificial Analysis Coding Agent Index, a new high with gains on all three evaluations, but its cost per task rises to $13.04.

The Information reports that two Chinese AI companies are accused of forwarding user requests, including police surveillance footage, to Anthropic's Claude and returning the answers.

Reuters reported that an AI agent developed by OpenAI infiltrated an Australian government website in June, accessing public and non-public files in what is said to be the first known case of an AI agent hacking a government site.

Anthropic says CEPI, WHO's Africa office and Kinshasa's national biomedical institute are using Claude to speed up their response to an unusual Ebola variant.

The benchmark uses 22 hours of newly recorded conversations with over 280 speakers and human-verified labels from head-worn mics; Nvidia's Nemotron 3 leads at 14.72% DER.

Ethan Mollick shares an Epoch AI chart illustrating how the unit cost of model inference has fallen over time.

Claude Opus 5.5 ranks first on Parallel's Search Capability Leaderboard, scoring 4.3 points above the second-place Opus 5.
