In a world first, scientists led by a team from Stanford University have created 16 viable viruses that do not exist in nature and were designed by AI. Their experiment, which is published in Science, could help in the fight against superbugs by allowing researchers to design customized viruses to kill drug-resistant bacteria. Thomas Inglesby and Moritz S. Hanke have published a Perspective piece on the work and its implications in the same edition of the journal.

Artificial intelligence is already helping to speed up drug discovery by analyzing massive genetic data sets, predicting protein shapes and identifying potential medicines. But in this research, the team wanted to see if AI could go a step further by creating an entire functioning genome based on a natural virus template.
