I describe some recent progress on Yang-Mills theories formulated on noncommutative spaces and in particular how to formulate the standard model on such spaces.

We show that the null energy condition is directly related to the signature of the kinetic term for small fluctuations in a broad class of classical field theories of scalars and gauge bosons. When the null energy condition is violated, instabilities necessarily arise. In models of the dark energy, where T_{00}>0, the null energy condition reduces to the condition that w\ge -1.
