Anthropic used its Claude AI in the Claude Science environment to design protein binders that could attach to scorpion neurotoxins. Claude generated 318,484 designs for five toxins from four scorpion species after a single prompt and then worked autonomously for 24 hours. Researchers narrowed the set to 211 candidates, testing them in the lab, and 17 met the criteria for binding. Two of those bound very tightly to the Cn2 toxin from the Mexican scorpion, docking near the site of an antibody that neutralizes the toxin in mice. The binders have not yet been tested as an antivenom.
Why it matters
If further development succeeds, the AI‑generated binders could become a faster, cheaper way to create antivenoms for scorpion stings that kill thousands each year.
