  We present new cosmological solutions for brane gases with solitonic fluxes
that can dynamically explain the existence of three large spatial dimensions.
This reasserts the importance of fluxes for understanding the full space of
solutions in a potential implementation of the Brandenberger-Vafa mechanism
with M2-branes. Additionally, we study a particular example in which the
cosmological dynamics supported by a string gas with a NS flux in the
ten-dimensional dilaton gravity framework is asymptotically equivalent to that
of a M2-brane gas with a certain wrapping configuration in eleven-dimensional
supergravity. We speculate that this connection between the ten- and
eleven-dimensional implementations of the Brandenberger-Vafa mechanism could be
a general feature.
