Microbial species living in a fruit fly gut interact with one another—and influence the insect’s health and longevity in the process.

The fungi are made to generate electricity with the help of photosynthesizing bacteria looped together on a graphene circuit. 

Microbes, traditionally thought to lack organelles, get a metabolic boost from geometric compartments that act as cauldrons for chemical reactions. Bioengineers are eager to harness the compartments for their own purposes.

Bacteriologist Alice Evans identified the pathogen that causes undulant fever, leading her to push for the pasteurization of milk.

These icosahedral structures are composed of proteins with unique geometric properties, which enable bacteria to employ them in a variety of situations.

A study of Danish adults reveals moderate changes in the abundance of multiple gut bacteria species, but the results might not be due to reduced gluten per se.

A case study of two patients with advanced cancer shows it might be possible to avoid a common and severe side effect of immunotherapy treatment.

A report also concludes that an investment of $2 per person per year could forestall that fate.

As people move to the United States from Southeast Asia, the microbes in their digestive tracts begin to Westernize, possibly explaining high rates of obesity and other metabolic issues in these immigrant populations.
