California Signs Gene Synthesis Biosecurity Law AB1864

The gist

The law creates enforceable standards where none previously existed for gene synthesis screening in California. Advocates argue it should serve as a model for equivalent federal and international standards.

The full picture

California Governor Newsom signed AB1864, which requires gene synthesis providers to screen orders and verify customers. The law converts previously voluntary biosecurity guidance from OSTP into an enforceable statutory requirement. Before AB1864, the existing framework was voluntary and relied on self-attestation with no mechanism for verification or enforcement.
