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.
