The issue of antibiotic resistance has led to a significant number of deaths globally, posing a major public health risk. Recent research utilizing artificial intelligence technology has successfully designed a new antibiotic, Protegrin-1.2, by screening thousands of variants. It effectively kills bacteria while significantly reducing damage to human cells. The study was led by Dr. Bryan Davis from the University of Texas, who used a system called SLAY to screen a vast number of antibiotic peptides, ultimately discovering this new selective antibiotic. Experiments showed that Protegrin-1.
