  Recent hydrodynamical simulations of supernova (SN) evolution have
highlighted the importance of a thorough control over microscopic physics
responsible for such internal processes as neutrino heating. In particular, it
has been suggested that modifications to the neutrino-nucleon elastic cross
section can potentially play a crucial role in producing successful supernova
explosions. One possible source of such corrections can be found in a nonzero
value for the nucleon's strange helicity content $\Delta s$. In the present
analysis, however, we show that theoretical and experimental progress over the
past decade has suggested a comparatively small magnitude for $\Delta s$, such
that its sole effect is not sufficient to provide the physics leading to
supernova explosions.
