AI can design viruses, toxins and other bioweapons. How worried should we be?
undefined 20, 2026
A Nature report examines concerns that AI used in biology could be misused to design toxins or even pathogens. While these tools are mainly built for drug discovery and protein design, scientists warn they could lower barriers to harmful biological engineering. Some experts fear AI could help create hard-to-detect toxins or engineered viruses, but others note major real-world limits like lab expertise, data gaps, and production hurdles. Debate continues over whether regulation, screening, or “guard rails” can effectively reduce risk.
