Scientists at Stanford University have used an artificial intelligence model to design new viral genomes. The research explores how AI can identify patterns in large collections of genetic information.
The researchers trained an AI model called Evo using millions of DNA sequences. The system learned genetic patterns and evolutionary features from the available genomic data.
The approach is similar to how language models learn patterns from large amounts of text. However, Evo was designed to process and generate biological sequences.
The researchers used the model to create new genetic sequences that did not directly match natural viral genomes. Selected sequences were then synthesized and tested under laboratory conditions.
According to Forbes, 16 of the AI-generated viruses successfully infected E. coli during the experiments. The viruses were functional bacteriophages capable of targeting the bacteria.
Some of the generated viruses also showed the ability to overcome resistance mechanisms. These mechanisms are naturally used by bacteria to defend against viral infections.
The findings suggest that AI can learn more than simple patterns in genetic material. It can also capture some evolutionary constraints linked to biological function.
The research demonstrates a growing role for artificial intelligence in biological science. AI models can process huge amounts of genetic information much faster than traditional approaches.
The Scientists involved in the research said they took steps to reduce potential biosecurity risks. Human pathogen data was excluded from the training process.
As a result, the viruses generated during the study were not designed to infect humans. The experiments instead focused on bacteriophages that infect E. coli.
The research has nevertheless raised questions among biosecurity experts. They warn that advances in AI-based biological design could create future risks.
Experts are concerned that powerful AI systems could eventually reduce barriers to designing harmful biological agents. They say appropriate safeguards will become increasingly important.
The study also demonstrates the potential benefits of AI for biological research. Similar technologies could help researchers investigate genetic systems and develop new scientific applications.
However, the ability to generate functional biological sequences requires careful oversight. Researchers must consider both scientific benefits and possible misuse.
The Scientists used laboratory testing to determine whether selected AI-generated sequences could function. The successful results provided evidence that the model had learned useful biological information.
The findings also show how AI can contribute to areas traditionally dependent on extensive laboratory research. Computer models can now help generate candidates for experimental testing.
The researchers’ work represents another step in the development of AI-assisted biotechnology. It also highlights the need for responsible use of advanced biological models.
The study does not indicate that the generated viruses were designed to infect humans. Instead, the experiments focused on viruses that infect bacteria.
The Scientists behind the research have demonstrated that AI-generated genetic sequences can produce functional biological systems. The findings could influence future research into AI and genomics.

At the same time, biosecurity remains an important consideration. Continued development will require safeguards that support scientific research while reducing potential risks.
