In 1928, Sir Alexander Fleming uncovered penicillin, an antibacterial compound that would alter the course of medicine. By the 1940s, this miracle drug entered clinical use, and humanity began to rely on penicillin and other antibiotics to treat once-lethal bacterial infections. Despite this success, bacteria continue to threaten global health as antibiotic-resistant strains emerge and spread. Scientists now race against time to develop new antimicrobial drugs before bacteria gain the upper hand. Fortunately, researchers have found a powerful ally: artificial intelligence.

In this episode, Charlene Lancaster from The Scientist spoke with César de la Fuente, a presidential associate professor at the University of Pennsylvania, to learn how his team is leveraging AI to discover novel antibiotics from unique sources, including spiders, archaea, woolly mammoths, and ancient and modern humans.
