Scientists used AI to write coherent viral genomes, using them to synthesize bacteriophages capable of killing resistant strains of bacteria.
"The researchers synthesized DNA from the AI-designed genomes and inserted them into host bacteria to grow phages. These phages were then experimentally tested to see whether they could infect and kill E.coli.
Some 16 of the 302 AI-designed bacteriophage showed host specificity for E. coli and could infect the bacteria. The researchers found that combinations of AI-designed phages could infect and kill three different E. coli strains, which the wild-type ΦX174 was unable to do."
