    Lag phase is no slouch

    Lag phase is no slouch

    The TWiM team explores how delivery of an enzyme into competitor cells leads to synthesis of (p)ppApp, depletion of ATP, deregulation of metabolic pathways, and cell death, and a refinement of our typical view of bacterial lag phase as a period of nonreplication.

The best microbiology podcast

I love this podcast and have been listening for years. I appreciate the vast scope of microbiology that is covered as well as the integration of current events. Each one of the hosts makes you feel like you know them personally. My first ASM-Microbe conference was in Atlanta a couple of years ago and admit that I was a complete fan girl when I got a seat during the the TWIM live taping.

Great lessons

I learn so much from TWIM. Microbiomes are made practically huge, to my scope of conceptual perception. I’m glad y’all enlarge my view on science
