I will talk about my joint work with Hsueh-Yung Lin, on constructing new homomorphisms from Cremona groups, and more generally groups of birational self-maps to free abelian groups, based on motivic techniques. This allows us to answer some old questions about Cremona groups, such as (non-)generation by elements of certain types.
