Weakly Interacting Massive Particles (WIMPs) have been the main focus of the Dark Matter (DM) community for many years. However, there are both experimental clues and theoretical motivation to think beyond the WIMP paradigm and consider new ideas in the search for DM. I discuss two such new directions. First I explore a new low-threshold direct-detection concept for DM, based on the breaking of chemical bonds between atoms. This includes the dissociation of molecules and the creation of defects in a lattice. With thresholds of a few to 10's of eV, such an experiment could probe the nuclear couplings of dark matter particles as light as a few tens of MeV. I also discuss the possibility of detecting solar neutrinos, including pp neutrinos, with this experimental concept. Second, I briefly discuss how it may be possible to constrain parameters of dissipative DM by measuring super massive black hole growth rate in Active Galactic Nuclei.
