A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that ...

The human gut is home to trillions of beneficial microbes that play a crucial role in health. Disruptions in this delicate ...

When the first humans moved out of Africa, they carried their gut microbes with them. Turns out, these microbes also evolved along with them. There is pronounced variation in the microbial composition ...

A pioneering study provides new evidence that gut microbes vary across primate species and can shape physiology in ways associated with differences in brain size and cognitive function A new study sug ...

We each carry thousands of different species of microorganisms in our gastrointestinal tracts, and that gut microbiome has a powerful influence on various aspects of our health. Scientists have been ...

Researchers find obelisks, mysterious RNA molecules in human bacteria that challenge our understanding of viruses and ...

The human gut microbiome is composed of thousands of different bacteria and archaea that vary widely between populations and individuals. Scientists from the Max Planck Institute for Biology in ...

Human breast milk contains its own microbial ecosystem, and new research suggests these microbes may help seed an infant’s gut. Most discussions of breast milk highlight nutrients, antibodies, and the ...
