At the beginning of the seminar, I introduce lattice effective field theory and how it can be used to study nuclear few- and many-body systems. I then describe several recent developments. The first addresses the question, what are the minimal elements of the nuclear force needed to produce the correct bulk properties of nuclei? The second is the development of first principles simulations of the liquid-gas transition in nuclear matter. If there is time remaining, I discuss several other developments in progress.
