Summary
This Nature Communications paper by Edison, Toner, and Esvelt demonstrates a critical vulnerability in U.S. DNA synthesis screening regulations. The authors show that current select agent regulations fail to prevent the acquisition of dangerous pathogens because they do not regulate individual DNA fragments—only complete sequences. By obtaining unregulated DNA fragments from multiple commercial providers, the researchers were able to collectively assemble genetic material sufficient for a skilled individual to synthesize the 1918 influenza virus. The paper argues that DNA fragments must be regulated as select agents to make synthesis screening effective and prevent potential biosecurity threats.

U.S. select agent regulations ignore easily assembled DNA fragments, making synthesis screening ineffective regardless of accuracy. We acquired unregulated DNA collectively sufficient for a skilled individual to generate 1918 influenza from dozens of providers, demonstrating that fragments must be regulated as select agents.
Current U.S. regulations governing select agent pathogens contain a critical loophole: they cover intact DNA sequences capable of generating harmful agents 1 , but ignore DNA fragments that can be assembled by anyone with modest laboratory skills (Fig. 1 ). Under this flawed system, providers have no legal obligation to monitor or restrict access. To explore this vulnerability, we fragmented DNA sequences encoding ricin toxin or 1918 pandemic influenza virus and ordered 2-8 pieces from each of 38 DNA synthesis providers 2 . The companies collectively provided enough (legal) 400–500 base-pair fragments to generate (illegal) intact constructs several times over. Laboratory tests of equivalent harmless sequences confirmed that the pieces could have been assembled into plasmids that would enable a skilled individual following public protocols to generate a virus that once killed 50 million people 3 . Responsible firms face an impossible choice: implement voluntary safeguards and potentially lose business to less cautious competitors, or ship dangerous but legal fragments. Market incentives discouraged them from verifying our identity, confirming a legitimate research purpose, or coordinating with others to determine whether we sought to obtain an intact agent. The question is whether policymakers will update select agent regulations to cover DNA fragments and enforce
