In the minimal cosmological model, dark matter is assumed to consist in a small fraction of massive neutrinos, and a large fraction of cold dark matter particles. I will show how cosmological data can be used to weight neutrinos and provide information on deviations from the minimal scenario. For instance, I will discuss current bounds on extra light relics, dark matter velocities, dark matter annihilation, or possible small interactions between dark matter and other species.
