From Wired:
For the first time, an artificial intelligence system has created a series of previously unknown viruses capable of infecting and eliminating certain types of bacteria. This breakthrough opens up new possibilities for combating bacterial resistance. However, it also raises concerns about the potential misuse of this technology to design biological weapons.
For several years now, scientists have been able to synthesize viruses from scratch; these are typically used to develop and evaluate antiviral drugs and vaccines, as well as to expand our understanding of how these microorganisms behave. However, the production of these viral genomes has primarily relied on replicating previously known pathogens or variants.
