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…
350: TWiM Goes to College
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…
349: Punctured to Death by Spikes
TWiM explains how mechano-bactericidal surfaces made from diverse materials and patterned with spikes kill bacteria on contact, and virus-host evolution is reshaped by microgravity aboard the…
348: The Bark Side of the Microbiome
TWiM explains the finding that owning a dog during adolescence alters the microbiota and improves mental health, and the molecular basis for multidrug efflux by an anaerobic-associated…
347: At Wound's Edge
TWiM explains how S. aureus pathogenicity is a dynamic, niche-specific choreography that constantly recalibrates in response to the host microenvironment, and short chain fatty acids produced by…
346: Metabolism and Porin Permeability
TWiM explains how competition for nutrients anticipates and potentially mitigate drug side effects on the gut microbiota, and metabolic control of porin permeability influences antibiotic resistance.…
345: Faster Than Rocks!
TWiM explains a biological mechanism that links sulfur and iron cycling in anoxic environments, and "swashing," a form of surface movement in which bacteria migrate without active propulsion. Hosts: …
344: Ant Yogurt and Fine Chocolate
TWiM reveals the bacteria, acids, and enzymes behind yogurt made with ants, and a defined set of microbes that reproduces attributes of fine flavor chocolate fermentation Hosts: Vincent…

TWiM explores two different ways that bacteria defend against phages through the synthesis of cyclic nucleotides. Hosts: Michael Schmidt and Mark O. Martin Become a patron of TWiM. Links for…
342: The Microbiome, Pancreatic Cancer, and Sleep Quality
TWiM explains studies that show that the oral bacterial and fungal microbiome are risk factors for pancreatic cancer, and the gut microbiome and pyruvate metabolism of older adults are a link between…
341: Sea Star Wasting Disease
TWiM reveals a Vibrio as the causative agent of sea star wasting disease, and using microcolony-seq to uncover phenotypic inheritance from single cells. Hosts: Michael Schmidt and Michele Swanson…
340: Microbes in Trees and Plants
TWiM explores the varied and distinct microbiome of trees, and an array of biopesticidal metabolites against mosquito larvae isolated from a Mediterranean island. Become a patron of TWiM. Links…
339: Missing the Company of Elio
TWiM pays tribute to Elio Schaechter, former TWiM host, blogger, and microbiologist extraordinaire, then reviews the finding that Archaea produce peptidoglycan hydrolases that kill bacteria - a form…

TWiM discusses outbreak of Legionnaires disease in Harlem NY, an automated whole genome sequencing platform for bacterial strain typing in clinical microbiology laboratories, building E. coli with a…
337: Lifestyles of the Plasmids
TWiM explains a study that examines pathogen presence in ancient humans and concludes that zoonoses emerged 6500 years ago with the domestication of livestock, and determination of universal rules…
