Mapping two-dimensional polar active fluids to two-dimensional soap and one-dimensional sandblasting

In many groups of moving organisms, such as swarms of bacteria, their constituents pack so tightly that density cannot change. Here, Chen et al.map such incompressible flocks in two dimensions onto the growth of a one-dimensional interface, and thereby compute the large-distance behaviour of such fl...
