This edition of iSquared magazine features:

Chemotaxis: how bacteria move - Nikita Vladimirov explains why mathematical modelling is useful for understanding chemotaxis, a mechanism used by bacteria to enable them to travel up chemical gradients towards nutrient–rich regions, find food and avoid toxins.

We’re not all prisoners in here - Chris Gaffney discovers how players can benefit from forming coalitions in Cooperative Game Theory. Chris looks at the transferable utility, the non-transferable utility and the marriage game.

Rheology: The science of deformation and flow - Tim Reis explores the mathematics behind some of the strangest phenomena in materials science, including the “miracle” of walking on custard. Certain materials have the ability to behave as either solids or liquids depending upon the types forces applied to them.

Interview:  Iain Clarke, quantitative analysis, explains how mathematics is used in the world of finance.
