The surprisingly resourceful ways bacteria thrive in the human gut

The gut microbiome is so useful to human digestion and health that it is often called an extra digestive organ. This vast collection of bacteria and other microorganisms in the intestine helps us break down foods and produce ...

Researchers construct most complex, complete synthetic microbiome

Key studies in the last decade have shown that the gut microbiome, the collection of hundreds of bacterial species that live in the human digestive system, influences neural development, response to cancer immunotherapies, ...

What guppy guts can teach us about evolution

On the list of scientific tools that help us understand health, evolution or the environment, the Trinidadian guppy doesn't often come to mind.

Unparalleled inventory of the human gut ecosystem

An international team of scientists has collated all known bacterial genomes from the human gut microbiome into a single large database, allowing researchers to explore the links between bacterial genes and proteins, and ...

Probiotic bacteria evolve inside mice's GI tracts

Probiotics—which are living bacteria taken to promote digestive health—can evolve once inside the body and have the potential to become less effective and sometimes even harmful, according to a new study from Washington ...

More than 100 new gut bacteria discovered in human microbiome

Scientists working on the gut microbiome have discovered and isolated more than 100 completely new species of bacteria from healthy people's intestines. The study from the Wellcome Sanger Institute, Hudson Institute of Medical ...

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.

Gut bacteria influence movement in flies

Warm, protected, and full of nutrients—the tiny intestines of a fruit fly are a perfect habitat for some bacteria. These bacteria, in turn, help the fly break down and digest food, keeping the insect's metabolism running ...
