Human gut microbes could make processed foods healthier

A new study from Washington University School of Medicine in St. Louis sheds light on how human gut microbes break down processed foods—especially potentially harmful chemical changes often produced during modern food manufacturing ...

Plants defend against insects by inducing 'leaky gut syndrome'

Plants may induce "leaky gut syndrome"—permeability of the gut lining—in insects as part of a multipronged strategy for protecting themselves from being eaten, according to researchers at Penn State. By improving our ...

Our microbes are starving, and that's a good thing

Each of us is only half human. The other half is microbial. Trillions of viruses, fungi, bacteria and other microscopic organisms coat our skin and line our vital organs.

Social bees have kept their gut microbes for 80 million years

About 80 million years ago, a group of bees began exhibiting social behavior, which includes raising young together, sharing food resources and defending their colony. Today, their descendants—honey bees, stingless bees ...

Our microbes, ourselves

In terms of diversity and sheer numbers, the microbes occupying the human gut easily dwarf the billions of people inhabiting the Earth. Numbering in the tens of trillions and representing many thousands of distinct genetic ...

Light flips genetic switch in bacteria inside transparent worms

Researchers from Rice University and Baylor College of Medicine have shown that colored light can both activate and deactivate genes of gut bacteria in the intestines of worms. The research shows how optogenetic technology ...

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 ...

Sampling the gut microbiome with an ingestible pill

Gut microbes affect human health, but there is still much to learn, in part because they're not easy to collect. But researchers now report in ACS Nano that they have developed an ingestible capsule that in rat studies captured ...
