On the occasion of TWiM’s 300th episode, we discuss how two college students found a new antibiotic in soil, Barbara Iglewski’s passing, and Elio returns for an appearance.
From ASM’s Conference for Undergraduate Educators 2023 in Phoenix, TWiM speaks with Amaya Garcia Costas and Gwendolyn Knapp about their approaches to undergraduate microbiology education, and how they use TWiM as part of their curricula.
TWiM provides thoughts on providing better training for a non-academic career, and help celebrate Black in Microbiology Week with a 2023 paper by Ari Kozik, a co-founder of Black Microbiologists Association and Assistant Professor at the University of Michigan.
TWiM reviews how a coating of lipoproteins provides a stabilizing environment on the inner membrane of Bacillus subtilis spores, and a miniaturized device that integrates genetically engineered probiotic biosensors with a custom-designed photodetector and readout chip to track mediators of inflammation in the gastrointestinal tract
TWiM discusses a dispute about whether the mycobiome plays a role in the development of cancer, and the structure and function of channels that are delivered to plant cells by pathogenic bacteria.
TWiM explains how phages avoid tRNA-targeting host defenses, and discovery of a new antibiotic from an uncultured bacterium that binds to an immutable target.
TWiM reveals that the ice cream manufacturing environment harbors psychrotrophic bacteria, and identification of a deadly bacterial strain causing widespread deaths of newborns in Uganda.
TWiM explains personalized aerosilized phage therapy for a chronic lung infection, and using the combination of antibiotic and a DNA molecule that binds alpha-gal to reduce S. aureus infection in vivo.
TWiM reveals that breast milk bioactives are essential for development of the infant microbiome and immunity, and how capsule mutants of Klebsiella pneumoniae can affect bacterial pathogenesis.
TWiM explains how photoferrotrophic bacteria initiated plate tectonics over 2500 million years ago, and how two bacteria work together to cause childhood tooth decay.
