They ordered a 78 “letter” piece of DNA for a smallpox envelope protein.
As they note, the actual genome is rather longer than that, but as they also note, there are techniques for reconstructing genomes from DNA pieces.
I don’t think anyone will be synthesizing smallpox from less than 100 base length pieces, got to be easier ways to do it (start from a chickenpox virus and edit it?); but they make an interesting if overhyped point.
Update: Nick at Scientific Activist also comments.
He notes that this suggests a need for more government regulation.
On reflection I think this is right, not because companies that sell custom DNA sequences on spec are evil or reckless, but because regulation, with moderately draconian penalties, will force honest (and most competent) companies to exercise due diligence (at some cost, but screening custom sequences against listed pathogens can’t be that high an effort). As the grauniad notes, the company they dealt with never even thought to check.
Actually synthethising something like smallpox de novo from short custom sequences seems unlikely, if terrorists could do that, why would they bother rather than doing something really nasty.
There might be an issue in this expediting the editing of harmless virii like cowpox into something nastier, change some proteins by adding sequences from worse virii, But, I’ll leave it to my betters to speculate on that.
Interesting, like living in the preamble to an Egan novel.
DNA is getting to be too easy.
Of course a Bondian level Evil Company would be indefensible – the DNA is just letters, there’s no safeguarding against what they actually send as opposed to what they say they sent in accounts.
But, a rational Evil Company would not expedite the synthesis of a war virus for any amount of money, because anyway it goes, they’re dead and have nothing to spend their ill gotten gains on. Right?
