Blow up a long balloon and two things happen: it gets longer and it gets wider. Now imagine a living cell that inflates itself under enormous pressure and yet only grows longer, never adding width.

Recent research indicates a link between an animal’s gut bacteria and brain function. This may be true in humans, too.

A colony of leafcutter ants is home to more than just one species. Each year, studies reveal new layers of complexity in these ecosystems, where ...

Bacteria and the viruses that infect them are perpetually at war. Their deadly clashes push both kinds of microbes to evolve ...

Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ protein, which normally forms a donut-shaped structure, must bend and ...

Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system. Shigella bacteria can infect humans ...

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 ...

Flour choice shapes the bacteria in sourdough starters, even though the same yeast dominates across all types.

Caste survives by regulating organic movement; it thrives by dramatising the ordinary; and it spreads by normalising the scripted norms ...

Scientists discover immune genes influence which gut bacteria live in animals by studying a tiny island bird population.
