How Canadian Researchers Reconstituted an Extinct Poxvirus for $100,000 Using Mail-Order DNA

(Science) – Eradicating smallpox, one of the deadliest diseases in history, took humanity decades and cost billions of dollars. Bringing the scourge back would probably take a small scientific team with little specialized knowledge half a year and cost about $100,000. That’s one conclusion from an unusual and as-yet unpublished experiment performed last year by Canadian researchers. A group led by virologist David Evans of the University of Alberta in Edmonton, Canada, says it has synthesized the horsepox virus, a relative of smallpox, from genetic pieces ordered in the mail. Horsepox is not known to harm humans—and like smallpox, researchers believe it no longer exists in nature; nor is it seen as a major agricultural threat.
