Electronic transport through quantum dots is influenced by correlations between the electrons. Whereas it is difficult to access such correlations in dc-transport experiments, fluctuations in the current as measured in shot-noise experiments or in direct counting of the tunneling electrons reveal much clearer the underlying correlations. Several recent experiments will be reviewed where universal oscillations in high cumulants of the counting distribution [1,2], finite frequency current statistics [3], and non-Markovian noise at a Fermi edge singularity [4] were observed. In addition experiments studying spin-dependent noise features will be presented.
