Rethinking the wild world of species diversity in microbes

University of Maryland biologists developed the first mathematical simulations of bacterial communities that incorporate the complex interactions and rapid evolution among bacteria and reflect the tremendous species diversity ...

How do microbes choose from a 'menu' of food?

Microbial communities often contain several species that coexist even though they share similar metabolic abilities. How they do so is unclear. Researchers have now developed a model to show that if these species have complementary ...

Safeguarding clean water for spaceflight missions

By all appearances, the universe beyond Earth is a vast, lonely, and sterile space. Yet, wherever humans may travel, an abundance of microbial life will follow.

Frequent fire too hot to handle for invasive plants

Land managers know one of the best ways to prevent forest fires is to set fires. Periodic controlled or prescribed burns can reduce the amount of flammable materials lying about on a forest floor, so when wildfires do start, ...

Black bear gut biome surprisingly simple, scientists say

In recent decades, researchers have found that most mammals' guts are surprisingly complex environments—home to a variety of microbial ecosystems that can profoundly affect an animal's well-being. Scientists have now learned ...

Glyphosate may affect human gut microbiota

Glyphosate is the most commonly used broad-spectrum herbicide. Researchers from the University of Turku in Finland have developed a new bioinformatics tool to predict if a microbe, e.g. a human gut bacterium, is sensitive ...
