  We consider a scenario, within the framework of the MSSM, in which dark
matter is bino-like and dark matter-nucleon spin-independent scattering occurs
via the exchange of light squarks which exhibit left-right mixing. We show that
direct detection experiments such as LUX and SuperCDMS will be sensitive to a
wide class of such models through spin-independent scattering. Moreover, these
models exhibit properties, such as isospin violation, that are not typically
observed for the MSSM LSP if scattering occurs primarily through Higgs
exchange. The dominant nuclear physics uncertainty is the quark content of the
nucleon, particularly the strangeness content.
