  A snapshot of the results for heavy-flavour observables in heavy-ion (AA)
collisions at RHIC and LHC obtained with our transport calculations is
displayed. The initial charm and beauty production is simulated through pQCD
tools (POWHEG+PYTHIA) and is validated through the comparison with data from pp
collisions. The propagation of c and b quarks in the medium formed in heavy-ion
collisions is studied through a transport setup based on the relativistic
Langevin equation. With respect to past works we perform a more systematic
study, providing results with different choices of transport coefficients,
either from weak-coupling calculations or from lattice-QCD simulations. Our
findings are compared to a rich set of experimental data (D-mesons,
non-photonic electrons, non-prompt J/\psi's) which have meanwhile become
accessible.
