Researchers are building complex mathematical models to understand cancer's evolution and how to treat it. Durham, NC - Two Duke researchers are focusing on the deadly mathematics behind the mutated genes and damaged cells that drive cancer.  "... read more »

A computer simulation of a virtual city containing two groups of people shows how the distribution of neighborhoods with a given racial makeup is likely to change as the density of households -- regardless of their group identity -- increases past a certain threshold.

Durham, NC - Racially and economically mixed cities are more likely to stay integrated if the density of households stays low, finds a new analysis of a now-famous model of segregation. By simulating the movement of families between neighborhoods in... read more »
