AI Designs Viruses That Kill Bacteria, Raising Questions About Synthetic Microbes

AI-Designed Viruses Raise Concerns as Hydrogen Industry Faces Reality Check A research team in California has successfully used artificial intelligence to propose new genetic codes for viruses, which were then able to replicate and kill bacteria. This breakthrough, described in a preprint paper, has the potential to accelerate research into artificially engineered cells and create new treatments. However, experts warn that it also marks an impressive first step toward AI-designed life forms. The team, led by researchers at the University of California, San Francisco, used machine learning algorithms to generate novel genetic sequences for viruses. These sequences were then tested in a laboratory setting, where they successfully replicated and demonstrated cytotoxic activity against bacterial cells. "This is a significant achievement that demonstrates the power of AI in designing biological systems," said Dr. David Baker, a professor at the University of Washington who was not involved in the study. "However, it also raises important questions about the potential risks and consequences of creating life forms using artificial intelligence." The development of AI-designed viruses has sparked concerns among experts, who warn that it could potentially be used for malicious purposes. "While this technology holds great promise for medical applications, we must also consider the potential risks and ensure that we are taking steps to prevent its misuse," said Dr. Jennifer Doudna, a biochemist at the University of California, Berkeley. Meanwhile, the hydrogen industry is facing a reality check as a new report from the International Energy Agency (IEA) highlights cancellations and delays in major projects. The IEA's report notes that several low-carbon hydrogen production methods are struggling to gain traction due to high costs and technical challenges. "This moment is a complicated one for the green fuel," said Dr. Fatih Birol, Executive Director of the IEA. "While we believe that hydrogen has great potential in the energy transition, it's clear that more work needs to be done to make it a viable option." The report highlights several major projects that have been cancelled or delayed, including a planned hydrogen production facility in the US state of Utah. The project, which was expected to produce 1,000 tons of low-carbon hydrogen per year, has been put on hold due to concerns over costs and technical feasibility. As researchers continue to explore the potential of AI-designed viruses, experts warn that it's essential to consider the broader implications for society. "We need to be careful about how we develop and use this technology," said Dr. Baker. "The potential benefits are significant, but so too are the risks." Background: Artificial intelligence has been increasingly used in biological research, including the design of new genetic sequences and the prediction of protein structures. However, the development of AI-designed viruses raises concerns about the potential for misuse. Additional Perspectives: Dr. Doudna noted that while AI-designed viruses hold great promise for medical applications, they also raise important questions about the ethics of creating life forms using artificial intelligence. "We need to have a nuanced discussion about the risks and benefits of this technology," she said. Current Status and Next Developments: The research team's findings are currently available in a preprint paper on the bioRxiv server, pending peer review. The study's authors plan to continue exploring the potential of AI-designed viruses for medical applications while also addressing concerns about their misuse. As the hydrogen industry faces a reality check, experts warn that more work needs to be done to make low-carbon hydrogen production methods viable. "We need to invest in research and development to overcome the technical challenges and bring down costs," said Dr. Birol. *Reporting by Technologyreview.*
