  We investigate the fate of baryons made out of u, d and s quarks in the
hadronic gas and the quark-gluon plasma, using nonperturbative lattice
simulations, employing the FASTSUM anisotropic Nf=2+1 ensembles. In the
confined phase a strong temperature dependence is seen in the masses of the
negative-parity groundstates, while the positive-parity groundstate masses are
approximately temperature independent, within the error. At high temperature
parity doubling emerges. A noticeable effect of the heavier s quark is seen. We
give a simple description of the medium-dependent masses for the
negative-parity states and speculate on the relevance for heavy-ion
phenomenology via the hadron resonance gas.
