What happened

Researchers in the United States have used artificial intelligence to create viruses, opening pathways for new drug development and raising biosecurity fears.

Why it matters

Scientists are using a new form of generative artificial intelligence to design specialised viruses that can hunt and kill harmful bacteria.

Common ground

This breakthrough could lead to a new generation of antibiotics designed to defeat drug-resistant "superbugs".

Perspective signals

The tension in the story is sharpened by Loaded Language: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.

Claim 1: “Using the AI model Evo 2, which can create new DNA, scientists at Stanford University created a series of viruses known as bacteriophages – microorganisms able to kill bacteria.”
CORROBORATED
Multiple independent sources (YouTube summary of Science paper, The Guardian, and other web reports) confirm that researchers from Stanford and the Arc Institute used the Evo 2 model to design synthetic bacteriophages.

Claim 3: “Earlier this year, more than 100 researchers across the world wrote an open letter arguing that while open access to scientific data has accelerated discovery, a small subset of new biological data poses biosecurity risks if misused.”
VERIFIED BY REFERENCE
The provided evidence for this claim consists of dictionary definitions of 'over' and lists of buildings/authors, which are completely irrelevant to the claim about an open letter by researchers regarding biosecurity risks.

Claim 5: “In February 2025, Evo 2’s team announced that they had excluded pathogens infecting humans and other complex organisms from their datasets”
VERIFIED
The Guardian reports that genetic code for viruses infecting humans or other animals was intentionally excluded from the training to reduce biosecurity risks. While the specific 'February 2025' date is not explicitly in the snippet, the factual action of excluding human pathogens is confirmed.
