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 TWiM team reveals the genetic mysteries of the Dead Sea Scrolls from sequencing of DNA, and 100 million year old living bacteria recovered from marine sediments.

The TWiMmers explore detection of SARS-CoV-2 on surfaces in an ophthalmology examination room, the ability of stressed populations of Yersinia bacteria to survive antimicrobial treatment within host tissues, and how volatile organic chemicals produced by soil microbes attract arthropods which in turn disperse bacterial spores.
