AI Creates Bacteria-Killing Viruses: 'Extreme Caution' Warns Genome Pioneer
16 of these designs created successful bacteriophages which were able to replicate and kill the bacteria.Brian Hie, who leads the Arc Institute lab, reflected on the moment the plates revealed clearings where bacteria had died. "That was pretty striking, just actually seeing, like, this AI-generated sphere," said Hie.How the designs were generatedThe team targeted bacteriophage phiX174, a minimal DNA phage with approximately 5,000 bases across 11 genes. Around 2 million bacteriophage were used to train the AI model, allowing it to understand the patterns in their makeup and gene order.

...By Alex HarringtonSports Contributing Writer0ShareNewsweek is a Trust Project memberSee more of our trusted coverage when you search.Prefer Newsweek on Googleto see more of our trusted coverage when you search.A California outfit has used artificial intelligence to design viral genomes before they were then built and tested in a laboratory. Following this, bacteria was then successfully infected with a number of these AI-created viruses, proving that generative models can create functional genetics."The first generative design of complete genomes."That's what researchers at Stanford University and the Arc Institute in Palo Alto called the results of these experiments.
