AI从零设计了16种病毒 —— 生物安全法是否已过时？

scientists at stanford and the arc institute used a generative ai model named evo to design complete viral genomes, successfully synthesizing 16 distinct viruses that replicate in bacteria, some faster than the natural phi x-174. trained on 9 trillion nucleotides and specific phage data, the model proposed 700,000 genomes, of which 285 synthesized sequences yielded 16 functional viruses, confirming ai can engineer robust biological tools. while the team excluded human-infecting virus data to ensure safety, the research highlights a disconnect between ai capabilities and government oversight, as current us policies restrict physical enhancement of pathogens but not the computational creation of novel biological agents. regulators like the nih admit purely computational design is exempt unless it targets known 'entities of concern,' creating a gap that experts fear could be exploited for designing harmful influenza variants or other threats.
