Rapid, single-cell analysis of microbiotas now possible

A single-cell method developed by RIKEN biophysicists, that can rapidly classify hundreds of thousands of bacteria according to species, promises to be an invaluable tool for discovering how gut, skin, ocean and soil microbes ...

How stress hormones guide bacteria in their host

In humans and animals, catecholamines such as epinephrine, norepinephrine, and dopamine are common stress hormones. Stress can increase the body's susceptibility to bacterial infections. In the laboratory, stress hormones ...

Breaking down glycosides in the gut and in nature

Rarely does a tool become more useful when it's broken, but that's just the case with C-glycoside, a molecule found in many plants, foods, and medicines. To be used by the body, C-glycosides must be broken down. Researchers ...

Aging and nutrients competition determine changes in microbiota

Research groups from Instituto Gulbenkian de Ciência (IGC) that study evolution, immunity and microbiology unveiled two new mechanisms in the microbiota: in older populations, the bacterium E. coli evolves in a way that ...

Bile acid-triggered bacterial adaptation characterized

When bacteria enter the digestive tracts of their hosts, including humans, they encounter a highly acidic environment. Bacteria have evolved elegant mechanisms to survive and colonize this habitat, such as highly resistant ...
