US researchers say they created ۱۶ viruses using AI, prompting hopes for medical advances and concerns about misuse.

US researchers have announced the creation of new viruses using artificial intelligence, a scientific first that raises hopes for advances in medical treatments while also stoking anxiety about the dangers of the frontier technology.
In findings published in the journal Science, researchers at Stanford University and the Broad Institute of MIT and Harvard said they used a naturally occurring phage – a type of virus that infects bacteria – as a template to generate thousands of genomes with AI.

The researchers chemically synthesised nearly ۳۰۰ of the genomes and tested them in laboratory conditions, resulting in ۱۶ “viable” viruses, according to the findings published on Thursday.
In tests, a mixture of the synthetic viruses proved more effective at killing E coli bacteria than the naturally occurring viruses, according to the findings.
“Our results demonstrate that generative models capture evolutionary constraints in DNA sequences with enough fidelity to produce complete bacteriophage genomes divergent from those observed in nature and with prespecified traits,” the researchers wrote in Science.
“Our approach expands what synthetic genomics can achieve alongside methods such as directed evolution and rational engineering, lays out a path for generating adaptive and resilient phage therapies against rapidly evolving pathogens, and establishes a foundation for the generative design of larger, more complex genomes.”
Brian Hie and Samuel King, two of the paper’s authors, did not immediately respond to requests for comment.
Isaac Bogoch, an infectious disease specialist at the University of Toronto and Toronto General Hospital who was not involved in the study, said the research raised both hopeful and concerning implications.
“AI-designed viruses could have some potential benefits, such as the creation of targeted bacteriophages that could possibly help us tackle antibiotic-resistant infections in new ways,” Bogoch told Al Jazeera.
“But that same ability to design whole, functional viruses could easily become a serious biosecurity risk if applied to harmful pathogens, so strong guardrails, screening, and oversight need to grow alongside the technology,” Bogoch said.
The milestone comes as rapid advances in the capabilities of AI stoke concern about the possibility of harm by malicious human actors or systems going rogue.
The United Kingdom’s government-run AI watchdog this week disclosed that Anthropic and OpenAI’s frontier AI models engaged in “autonomous” and “unsanctioned” malicious activity targeting real people and organisations during a recent routine safety evaluation.
The AI Security Institute said the rogue activity included an incident in which Anthropic’s Claude Mythos ۵ created fake online identities in a bid to insert malicious code into an open-source project on a developer platform.
The watchdog’s findings followed announcements by OpenAI and Anthropic last month that their top-end models had engaged in hacking sprees against several organisations without human prompting.
After championing light-touch regulation early in his second term, US President Donald Trump has taken an increasingly hands-on approach to AI regulation.
In June, Trump signed an executive order to establish a voluntary framework for evaluating frontier AI models ahead of their release.
The Trump administration has not publicly released its evaluation criteria or methods, drawing criticism from tech industry observers.
