Scientists Make First Viruses Designed By AI

3 weeks ago
An anonymous reader quotes a report from The Guardian: Scientists have made the first viruses designed by artificial intelligence in a milestone that raises hopes for new medicines but also concerns over how to ensure the technology remains safe. The viruses are specific kinds known as bacteriophages, which only infect bacteria and are used around the world to treat patients with persistent infections. In lab tests, a cocktail of the AI-designed viruses killed E coli bugs that were resistant to natural bacteriophages. Dr Brian Hie, a chemical engineer at Stanford University in California, used genome language models, the genetic equivalent of the large language models behind AI chatbots, to design functioning genomes for bacteriophages. The viruses were then made in the laboratory and pitted against E coli in a dish. The ability to "rapidly design" genomes and tune them for specific bugs while overcoming resistance could "transform phage therapy" and "expand biotechnological toolkits," the researchers wrote in the journal Science. But beyond the potential benefits, the scientists said the work raised "important biosafety, biocontainment and biosecurity considerations" and urged others who were designing whole genomes to "consult both safety and security professionals throughout the project." In an accompanying article, Prof Tom Inglesby and Dr Moritz Hanke at the Center for Health Security at Johns Hopkins University in Baltimore, reinforced the warning, writing: "Although this is promising for life sciences applications, it also raises urgent biosafety and biosecurity questions. The ability to compose viral genomes using generative AI now exists; the governance to safely steer it does not." Tom Ellis, a professor of synthetic genome engineering at Imperial College London, said the work was impressive, but revealed how hard it would be to make more complex genomes. "This is literally the smallest and easiest genome to make," he said. An AI trained on the genetic code of dangerous bugs could be used to design more harmful viruses, Ellis said, but controlling access to genetic data and having restrictions on making genomes that look dangerous would help. "Governments are working hard to do this already," he added. "But honestly," he said, "the threat from full AI design and writing of a genome of a virus or bacteria is very overblown when we consider that just taking existing pathogens and making gain-of-function changes to their genomes is so much easier and much more likely to be a real pathogenic threat." Dr Filippa Lentzos, a reader in science and international security at King's College London, said the most important point to intervene at the moment was when DNA was being manufactured. "It's important to see the bigger governance picture and not focus regulation solely on the AI model," she said. "A layered approach makes more sense: safeguards around model development and access, responsible research review, synthesis screening, and established laboratory biosafety and biosecurity."

Court Orders Meta To Establish $567 Million Fund To Abate Harms To Youth

3 weeks ago
A New Mexico court ordered (PDF) Meta to create a $567 million fund to address harms linked to youth mental health and child sexual exploitation after finding its platforms constituted a public nuisance. "In sum, the Court finds that New Mexico is in the midst of a teen mental health crisis affecting public health and public safety in and throughout the state, and that Meta's platforms are a significant contributing cause to the crisis," wrote Chief Judge Bryan Biedscheid in the decision. The fund comes on top of $375 million in civil penalties, though the judge declined to mandate changes to features such as infinite scroll and autoplay, citing potential First Amendment and Section 230 concerns. Tech Policy Press reports: The decision follows the second phase of in the State of New Mexico v. Meta Platforms Inc., which consisted of a bench trial. Its central question was whether Meta's platforms amounted to a public nuisance in New Mexico, and, if the court found that they did, what remedy would be needed to address it. In March, a Santa Fe jury found Meta liable for violations of New Mexico's Unfair Practices Act, awarding $375 million in civil penalties. The jury deliberated less than a day following that nearly seven-week trial. The $567 million abatement fund would be in addition to the civil penalties, according to today's decision. New Mexico Attorney General Raul Torrez sued Meta in December 2023, alleging the company made false public statements about the safety of its platforms while knowing internally that its products facilitated child sexual exploitation. The court denied Meta's Section 230 defense in May 2024. In today's decision, the court again asserted that "Section 230 does not preclude the State's public nuisance claim," but the decision attempted to thread the needle on issues that the court determined might have run "afoul" of the statute, or of the First Amendment, such as issuing remedies around any particular product feature.
