Researchers have discovered that the artificial sweetener saccharin has powerful antimicrobial properties. A new study published in EMBO Molecular Medicine suggests that saccharin can actually kill antibiotic resistant bacteria by interfering with DNA replication and cell division. The researchers also concluded that, with the help of traditional antibiotics, saccharin could even be used as an effective wound treatment.

Host Ira Flatow talks with study author Dr. Ronan McCarthy, professor in biomedical sciences and director of the Antimicrobial Innovations Centre at Brunel University of London.
