Anomalies are of great importance both because of their formal peculiarities and their practical consequences. In this talk I’ll first review some of their general aspects. Then, I’ll consider in more detail some recent results regarding the trace anomaly. I’ll devote particular attention to the trace anomaly of a chiral fermion, for which a possible odd-parity contribution has recently generated a controversy.
