New documents may explain why no one has been able to find the SARS2 virus (aka SARS-CoV-2) infesting a colony of bats, from which it might have jumped to people. The reason would be that the virus has never existed in the natural world. Documents obtained by U.S. Right to Know, a health advocacy group, provide a recipe for assembling SARS-type viruses from six synthetic pieces of DNA designed to be a consensus sequence—the genetically most infectious form—of viruses related to SARS1, the bat virus that caused the minor epidemic of 2002. The probative weight of the recipe is that prior independent evidence already pointed to SARS2 having just such a six-section structure.

The documents unearthed by U.S. Right to Know, and analyzed by its reporter Emily Kopp, include drafts and planning materials for the already-known DEFUSE proposal, an application to DARPA, a Pentagon research agency, for a $14 million grant to enhance SARS-like bat viruses.

The new recipe is in striking accord with a theoretical paper published in 2022 that predicted the SARS2 virus had been generated in exactly this way. Three researchers—Valentin Bruttel, Alex Washburne, and Antonius VanDongen—noted that the virus could be cut into six sections if treated with a pair of agents known as restriction enzymes and so had probably been synthesized and assembled in this way.

[The lab leak was always the most rational of the explanations. The “wet market” hypothesis was strange at the time, and in retrospect looks like a clumsy cover-up by Beijing. It was well known by health officials in the US that the lab in Wuhan was doing the kind of gain-of-function research that could produce such a novel coronavirus, AND that it had substandard security protocols for that kind of activity. Instead of opting for transparency, the healthcare and political establishments punished anyone who suggested the lab-leak theory as a possible explanation. — Ed]
