Description
For the first time ever, scientists used generative AI to design complete genomes from scratch, producing novel bacteriophages that effectively inhibit their target bacterial hosts.
The researchers trained AI models on millions of phage genomes, then generated hundreds of new designs using a well-known E. coli phage as a template. After synthesizing the genomes—which had similarities to natural phages, though also some newly introduced sequence variation and diversity—they found that 16 of the phages could successfully inhibit their bacterial target in the lab.
Notably, when bacteria evolved resistance to the template phage, cocktails containing the AI-generated phages were able to overcome that resistance, while comparable natural phage cocktails could not.
The findings highlight the potential of AI-driven genome design for biotechnology and future phage therapies. But they also raise important questions about biosafety, security and governance as this technology advances.
