Recent results from KTEV with Hyperon beta and weak-radiative decays, and new measurements from the HyperCP experiment on Flavour Changing Neutral Currents and rare K14 decays will be presented. The common thread in this diverse collection of decays is an attempt to improve our understanding of weak processes at the quark-diagram level by either confirming the decay of mechanism of the Standard Model or demonstrating that new physics is required. All of the decays presented, and more, can be studied in greater precision with scheduled special runs of the NA48 experiment.
