AI has designed bacteria-killing proteins from scratch – and they work

An AI has designed anti-microbial proteins that were then tested in real life and shown to work. The same approach could eventually be used to make new medicines. Proteins are made of chains of amino acids. The sequence of those acids determine the protein's shape and function. Ali Madani at Salesforce Research in California and his colleagues used an AI to design millions of new proteins, then created a small sample of those to test whether they worked.
