Query: Constructing stable de Sitter in M-theory from higher curvature
  corrections   We consider dimensional reductions of M-theory on
$\mathbb{T}^{7}/\mathbb{Z}_{2}^{3}$ with the inclusion of arbitrary metric flux
and spacetime filling KK monopoles. With these ingredients at hand, we are able
to construct a novel family of non-supersymmetric yet tachyon free Minkowski
extrema. These solutions are supported by pure geometry with no extra need for
gauge fluxes and possess a fully stable perturbative mass spectrum, up to a
single flat direction. Such a direction corresponds to the overall internal
volume, with respect to which the scalar potential exhibits a no-scale
behavior. We then provide a mechanism that lifts the flat direction to give it
a positive squared mass while turning Mkw$_{4}$ into dS$_{4}$. The construction
makes use of the combined effect of $G_{7}$ flux and higher curvature
corrections. Our solution is scale separated and the quantum corrections are
small. Finally we speculate on novel possibilities when it comes to scale
hierarchies within a given construction of this type, and possible issues with
the choice of quantum vacuum.
