Claude designs 17 lab-confirmed protein binders against scorpion neurotoxins

Source: AnthropicAlso reported by The Verge

Anthropic said an internal research model working in Claude Science, mostly on its own over 64 hours with four follow-up prompts, generated 318,484 protein designs aimed at scorpion neurotoxins and picked 180 for testing; Anthropic’s team added 31. Adaptyv Bio and Twist Bioscience tested all 211 in the lab, and 17 bound one of four neurotoxins dangerous to humans. Anthropic says it has not confirmed that any binder neutralises venom, so it does not claim an antivenom, and it is releasing all 211 designs and their data; the project began as a question from Citrini Research.

Why it matters

It shows an AI model producing lab-confirmed drug-discovery leads for a neglected disease in days, one step short of a tested treatment.
