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 ...

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 ...

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 ...

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 ...

How cell colonies organize and structure themselves is important in many areas. The study may therefore also provide new starting points for experimental and medical research -- for example for ...
