...simple proportional relationship to bacterial population density. Rather, the release of autoinducer substantially increases at a critical population level (dashed vertical line in Figure 3). This surge in autoinducer release underlies the coordinated change from planktonic to group behaviour. Cellular signalling systems often show rapid changes in activity beyond a...

...simple. Imagine a giant grid extending over the whole of space. Figure 6 shows the two-dimensional case, with a grid extending over part of the page. The grid is calibrated (in centimetres) so the position of any point can be specified by giving its x- and y-coordinates on the grid. For example, the coordinates of point A are x = 3 cm and y = 4 cm. [Figure 6] Figure 6 A...

...simple plane of identical atoms – fully three-dimensional networks are more realistic but less easy to draw. [Figure 4] Figure 4 Atoms in a solid can be represented as spheres, arranged in planes as a component of some three-dimensional configuration What happens if we try to force the atoms closer together, say by compressing the solid, squeezing it uniformly from all...
