In labs, bacterial colonies usually grow in streaks in petri dishes, but until now no one has known how the colonies organize themselves in more realistic three-dimensional (3-D) environments, such as ...

Dense E.coli bacteria have several similar qualities to colloidal glass. Colloids are substances made up of small particles suspended within a fluid, like ink for example. When these particles become ...

A 3D rendering captured using a confocal microscope shows the development of serpentine “cables” as non-motile E. coli bacterial cells proliferate in a polymeric solution. Scientists at Caltech and ...

Biofilms, ubiquitous bacterial communities embedded in a slimy matrix, are the oldest form of multicellularity on earth; they are extremely resistant to antibiotics and stick tenaciously to most ...

The interaction between growth and the active migration of cells plays a crucial role in the spatial mixing of growing cell colonies. This connection will lay the groundwork for new approaches to ...
