AI Designs Working Virus From Scratch

Scientists have successfully used AI models to design and create working viruses entirely from scratch. Two AI models, Evo 1 and Evo 2, generated approximately 300 viral genomes, leading to the creation of 16 viable viruses. These viruses, built upon the structure of a harmless bacteriophage (ΦX174), target only lab bacteria and are incapable of infecting humans.

The AI models were trained on extensive datasets of viral genomes, learning the language of DNA. However, the process required significant human oversight, with most AI-generated designs failing to produce viable viruses. The team had to filter and refine the outputs to achieve success, highlighting that AI acts as a tool rather than an autonomous creator.

This research holds significant implications for phage therapy, a method using viruses to combat antibiotic-resistant bacteria. While the current viruses are harmless, the underlying AI technology could accelerate the design of other complex biological systems. Concerns about misuse are mitigated by the current limitations in physically constructing and testing such designs, along with built-in safety protocols.

Safeguards were a priority, with researchers deliberately excluding viruses that infect complex organisms from training data and conducting work in secure labs. The scientific community is calling for further evaluation and regulatory measures to prevent the potential misuse of AI in designing dangerous pathogens.
