  New physics results with identified particles at STAR are presented.
Measurements at low $p_T$ address bulk properties of the collision, while those
at high $p_T$ address jet energy loss in the bulk matter produced. Between
these extremes, measurements at intermediate $p_T$ address the interplay
between jets and the bulk. We highlight: measurements of $v_2$ fluctuations as
a new, sensitive probe of the initial conditions and the equation of state;
correlations involving multi-strange particles, along with ratios of identified
particles to test coalescence as a mechanism of particle production at
intermediate $p_T$; three particle azimuthal correlation to search for conical
emission; and the energy and particle-type dependence of hadron production at
high $p_T$ to study quark and gluon jet energy loss.
