Dynamic modeling helps predict the behaviors of gut microbes

The human gut is teeming with microbes, each interacting with one another in a mind-boggling network of positive and negative exchanges. Some produce substances that serve as food for other microbes, while others produce ...

How germs thrive on school desks

Looking at the microbial communities that grow on students' desks, a team of Yale researchers found that the bacteria and fungi overwhelmingly came from the children sitting at the desks. They also found that, even after ...

Searching the sea, and bacterial battles, for new antibiotics

Alexander Fleming's discovery of penicillin—the world's first natural antibiotic—is famously told as a story of serendipity: a petri dish growing bacteria was contaminated by mold, which secreted a substance to keep bacteria ...

Researchers devise new way to discern what microbes eat

A new technique devised by researchers from North Carolina State University and the University of Calgary provides a more in-depth look at the metabolism and physiology within microbial communities—the microscopic life ...

Could we work together with our bacteria to stop infection?

The benefits of antibiotics to both human and animal health are undisputed. However, as microbes have become increasingly resistant to antimicrobials and other drugs, scientists have become interested in new solutions to ...
