  Recent observations of GeV gamma-rays from novae have led to a paradigm shift
in the understanding of these objects. While it is now believed that shocks
contribute significantly to the energy budget of novae, it is still unknown if
the emission is hadronic or leptonic in origin. Neutrinos could hold the key to
definitively differentiating between these two scenarios, though the energies
of such particles would be much lower than are typically targeted with neutrino
telescopes. IceCube's densely instrumented DeepCore sub-array provides the
ability to reduce the threshold for observation from 1 TeV down to
approximately 10 GeV. We will discuss recent measurements in this low energy
regime, details of a new sub-TeV selection, and prospects for future searches
for transient neutrino emission.
