TWiM discusses the use of bacteriophage-loaded microneedle patches for targeted and minimally disruptive foodborne pathogen decontamination, and a conjugal gene drive-like system that efficiently suppresses antibiotic resistance in bacteria.

Nancy and Maggie join TWiM to share how and why they created a freely available ebook of TWiM-based science literacy resources and classroom exercises that support teaching across key microbiology and molecular biology topics.
