The Science paper researchers carried out a test on biosecurity software used to screen customer orders by companies that sell synthetic nucleic acids. <\/p>\n
These are deployed by the clients to build DNA that instructs the manufacture of desired proteins, the building blocks of life. The biosecurity screening is designed to block the sale of materials that could be used to make harmful proteins.<\/p>\n
The researchers used open-source AI protein design software to generate computational renderings of more than 75,000 variants of dangerous proteins with structural tweaks \u2014 a kind of biochemical disguise. While the screening tools worked well for flagging naturally-occurring proteins of concern, they did not spot some of the altered ones, the scientists found. <\/p>\n
Even after all but one of the companies applied the software patches, about 3 per cent of the protein variants most likely to retain hazardous functionality still passed the monitoring undetected.<\/p>\n
The scientists worked with organisations including the International Gene Synthesis Consortium and US authorities to address the problem. <\/p>\n
The research comes after some leading scientists have called for a systematic assessment of biosecurity screening software and improved global governance of AI-boosted protein synthesis. <\/p>\n
High-profile biologists are also pushing for an international agreement to prevent the creation of potentially deadly manufactured \u201cmirror\u201d microbes<\/a>, should it become technologically possible to make them.<\/p>\n Horvitz said there had been an \u201cintensity of reflection, study and methodology\u201d about the prospect that large language models could be used to further \u201cmalevolent actions with biology\u201d. <\/p>\n Microsoft had incorporated such possibilities in its product safety reviews and had a \u201cgrowing set of practices\u201d about \u201cred-teaming\u201d, or searching for potential vulnerabilities.<\/p>\n The Science study highlighted a \u201cpressing issue in protein engineering and biosafety\u201d, said Francesco Aprile, associate professor in biological chemistry at Imperial College London.<\/p>\n Recommended<\/p>\n
