If the next generation of cosmological surveys are to realise their potential
of discovering new physics, more effort must be directed towards understanding
non-linear contributions to probes of cosmic density fluctuations. My talk will
cover two examples of recent progress in this endeavour. In the first half I
will discuss a new method aimed at enhancing the information content of
clustering statistics with non-linear Gaussianizing transforms. In the second
half I will present recent calculations of several new contributions to the
lensed CMB and discuss their implications for measuring primordial
gravitational waves.
