Scientists have used Artificial Intelligence to design new viruses capable of killing cells in the laboratory. The AI suggested thousands of genomes, and the researchers created 302 in the lab before exposing them to bacteria. Overall, 16 of the viruses suggested by the AI were able to kill E.coli. For the research, published in Science, scientists used the AI tools Evo1 and Evo2. Still, he cautioned against overblowing the threat: 'The threat from full AI design and writing of a genome of a virus or bacteria is very overblown.
