headline: Could AI ‘change the stakes’ in the development of bioweapons?
dek: In his annual speech on threats to the nation, Sir Ken McCallum, the head of the UK’s intelligence service, MI5, warned that AI had the potential to “change the stakes” on existing and even new bioweapons. Here we look at how AI might help in the development of bioweapons and the hurdles that remain. How could AI help people make bioweapons? It depends on who wants to make them. One risk is the rogue, unskilled bad actor or terrorist group that works from a garage laboratory. AI chatbots could help them skill up…

problem_reading: AI tools can supply dangerous pathogen and toxin information and may amplify skilled actors, while no country has formal policies against such misuse and DNA synthesis screening is largely voluntary.
problem_evidence: We have no formal government policies in place in any country yet to protect against this kind of misuse | it is largely voluntary, and can be sidestepped
quick_read: The head of MI5 warned in an annual threat speech that AI could change the stakes on existing and new bioweapons. The article lays out two routes of concern: unskilled actors using chatbots to compile information and troubleshoot, and well-resourced states using AI to enhance expertise, for instance by tweaking pathogens to be deadlier.

The concern matters because evidence is accumulating that chatbots can give hazardous guidance, while protections are patchy and dual-use research blurs defensive and offensive aims. What remains unclear is how far information alone helps, since experts stress that tacit knowledge, materials, equipment and delivery remain major obstacles.
limitation: The source says it is unclear whether AI responses helped in the ricin case, and Anthropic's cases only 'may have been' dangerous, so real-world uplift remains unproven.
tag: Evidence-backed problem
key_points: Indian police uncovered a suspected plot in which a doctor and others allegedly used AI chatbot queries to try to make ricin, though it is unclear whether the AI helped. | Anthropic reported five cases of scientists in unnamed countries trying to use Claude for possibly dangerous virus or toxin work, and some found workarounds after being blocked. | In an MIT exercise, non-science students got chatbots within an hour to list four potential pandemic pathogens and name DNA synthesis companies unlikely to screen orders. | Experts say tacit expertise, access to biological materials, validation, scale-up and delivery remain substantial barriers. | Proposed measures include independent pre-release model evaluations, restricting high-risk biological data, and mandatory screening of genetic material orders.
rundown: The article distinguishes near-term and distant risks. Dr Filippa Lentzos considers amplification of existing expertise at well-resourced organisations the more immediate worry, while designing wholly new drug-resistant pathogens or toxins with no antidotes is a more distant possibility.

Dual-use ambiguity complicates assessment. Los Alamos researchers trained an AI in 2025 to predict how marine snail neurotoxins bind human cells, work that could aid antidotes, but the US government grew concerned when Chinese researchers drew on it to build a toxin-design tool, which they said was only for drugs. In April, scientists made the first AI-designed viruses, ones that only infect bacteria.

Sceptical experts say material access is decisive. Prof Martin Pačesa argued that if someone has access to materials and facilities, AI will not make much difference, and Sonia Ben Ouagrham-Gormley noted that tacit knowledge drove historical state programmes.

On safeguards, Prof Tom Inglesby said most AI companies do not announce what they are doing, and that existing DNA synthesis screening can be bypassed if AI designs novel harmful sequences the companies are not checking for.
