TWiM

This Week in Microbiology

As a science Professor at Columbia University, Racaniello has spent his academic career directing a research laboratory focused on viruses. His enthusiasm for teaching inspired him to reach beyond the classroom using new media. TWiM is for everyone who wants to learn about the science of microbiology in a casual way.

While there are no exams or pop quizzes, TWiM does encourage interaction with the audience via comments on specific episodes (below), vial email and voicemail at 908-312-0760. Listeners can also use MicrobeWorld to suggest topics for the show by submitting articles or papers to the site and tagging them with "TWiM". Each week Racaniello will view the tagged content and select items for discussion.

TWiM co-hosts include Elio SchaechterMichael Schmidt, and Michele Swanson.

Music used on TWiM is composed and performed by Ronald Jenkees and used with permission.

Diderms and then monoderms - TWiM 136

Written by

The TWiM team discusses the importance of neutrophils in microbial infections, and evidence that ancient bacteria had two cell walls.

Bacteria learn long division - TWiM 132

Written by

Mice behaving badly - TWiM 131

Written by

Michael and Vincent present Spotlights, brief reviews of classic papers in the Journal of Bacteriology, and explain how a single bacterial species can reverse autism-like social deficits in the offspring of obese mice.

The TWiMers get together at ASM Microbe 2016 in Boston to speak with David and Vanessa to talk about their work on regulation of bacterial virulence in the gut by bacterial adrenergic sensors, and the physiological mechanisms that make us ill and that help us recover.

The arrival in the US of plasmid-mediated resistance to colistin antibiotics, a last line of defense against many gram-negative bacilli, and a quorum sensing system in a eukaryote are topics of this episode hosted by Vincent, Michael, and Michele.

A moonlighting phage protein - TWiM 128

Written by

A eukaryote without a mitochondrion, and using a phage enzyme to eliminate intracellular bacteria are two topics discussed by the TWiMers on this episode.
