Claude designed proteins that bind scorpion toxins
On October 20, 2026, Anthropic published a report stating that its internal research model, Claude, nearly autonomously conducted a de novo protein design campaign against five scorpion neurotoxins, with independent laboratories Adaptyv Bio and Twist Bioscience confirming binding in 17 of the 211 synthesized proteins. For biotech, this is one of the first documented cases of an LLM agent leading a multi-day (64-hour) autonomous scientific campaign: Claude itself found toxin structures in open PD
