I will discuss the most recent results from PICO, a search for particle dark matter using rather unconventional bubble chambers (as in listening to the sound of particle interactions…). I will then move on to COHERENT, an ongoing effort at ORNL's Spallation Neutron Source seeking to exploit the recentlymeasured coherent elastic neutrino-nucleus scattering (CEvNS) as a new tool for neutrino physics. The common ground between these two projects is the detection of keV and sub-keV nuclear recoils. The challenges in developing and understanding detector technologies sensitive to these will be emphasized.
