Several next-generation experiments aim to make the first measurement of the neutrino flux from the Carbon-Nitrogen-Oxygen (CNO) solar fusion cycle. This will provide crucial new information for models of the Sun, which currently are not able to consistently explain both helioseismology data and the abundance of metal elements, such as carbon, in the solar photosphere. I look at how soon experiments such as SNO+, Borexino and Argo will measure the CNO neutrino flux, and the challenges this involves.I also consider experiments looking for nuclear-recoils from CNO neutrinos, which requires sensitivity to very low energies, and discuss how the same technology is also key to direct searches for sub-GeV mass dark matter. Finally, I will discuss the detection of neutrino bursts from a future galactic supernova in Hyper-Kamiokande and IceCube, and how this can be used to detect or rule-out the presence of eV-mass sterile neutrinos.
