A growing body of research now links the trillions of microbes living in the human gut to how well people age, with recent studies identifying specific bacterial signatures that distinguish healthy ...

Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can’t be grown in the ...

Bacteria come in all shapes and sizes -- some are straight as a rod, others twist like a corkscrew. Shape plays an important role in how bacteria infiltrate and attack cells in the body. The helical ...

Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the ...

We often hear about bacteria, but what exactly are they? A bacterium is a living organism that consists of a single cell (unicellular). It has ...

A sweeping new study has uncovered global patterns in how bacteria thrive and interact within lakes and reservoirs, offering new insights into the invisible forces that sustain freshwater ecosystems.
