No matter how much they brush their teeth, some people still get more cavities than others, in part because of differences in ...

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 ...

The human body has always been crowded with microscopic passengers, from bacteria to viruses and fungi. Over the past two ...

A new study from Northwestern University is reshaping how scientists think about brain evolution. The research suggests that the gut microbiome does more than aid digestion. It may also influence how ...

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. A consortium led ...

What if your gut microbes helped power your brain? A new study reveals that the energy-hungry human brain may have evolved with a big assist from our gut bacteria. By transplanting gut microbes from ...

A major new review of human studies finds consistent differences in gut bacterial communities between people with mild ...

A new study suggests gut microbes can help protect humans from toxic, long-lasting "forever chemicals." Scientists at the University of Cambridge have identified that a natural "gut microbiome could ...

New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals’ brains began to ...

A team of scientists in Switzerland is collecting and deep-freezing human poop in what they call a "doomsday" vault. The goal is to protect the invisible microbial world inside us for future ...
