Evolution: No social distancing at the beginning of life

Bacteria are a dominant form of life that inhabit every environment on Earth. This includes human bodies, where they outnumber our cells and genes and regulate many body systems. Bacteria are regularly viewed as simple, single-celled ...

Mechanical forces of biofilms could play role in infections

The vast majority of bacteria in the world live on surfaces by forming structures called biofilms. These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that ...

Deprived of oxygen, layers of bacteria get creative

Bacteria are found living nearly everywhere on our planet, from the inside of human intestines to the soil to deep underwater. When scientists study bacteria in the lab, they most often examine individual bacterial cells ...

How a gooey slime helps bacteria survive

Bacteria have the ability to adapt to their environment to survive the host's immune defense. One such survival strategy includes the formation of a biofilm that prevents the immune system or antibiotics from reaching the ...

Bacteria breakthrough could lead to new biomaterials

Physicists at the Australian National University (ANU) have found a way to manipulate the growth of bacterial biofilms—one of the most abundant forms of life on earth.

Mechanical forces shape bacterial biofilms' puzzling patterns

Belying their slimy natures, the sticky patches of bacteria called biofilms often form intricate, starburst-like patterns as they grow. Now, researchers at Princeton University have combined expertise in molecular biology, ...

Bacteria form biofilms like settlers form cities

Microbiologists have long adopted the language of human settlement to describe how bacteria live and grow: They "invade" and "colonize." Relations dwelling in close proximity are "colonies."
