Greetings from Pittsburgh!

Today’s digest is unintentionally themed around change. Included is an article on the metabolic versatility of Salmonella enterica and another on the genetic diversification of Escherichia coli. If you’re more interested in the big picture, there is also an article about the evolution of ecological niches in plant-associated microbes as well as an article about the impacts of global change on soil microbial diversity and functionality.

Here’s to hoping that we are just as resilient as the microbes we study!

Events and jobs

A special plug for the National Summer Undergraduate Research Project (NSURP). NSURP is a community-driven initiative to create rewarding remote summer research opportunities for BIPOC undergraduate students in the microbial sciences. They are actively recruiting mentors and students for this summer, with the hope to match pairs by June 22nd.
