Heavy-quarks are, due to their large mass, unique tools to probe the quark gluon plasma created in high-energy nuclear collisions. In proton-proton collisions, heavy-quark production comprises a fundamental challenge to theory and experiment. We report on recent results from the ALICE experiment on heavy flavour production in $pp$ and $Pb-Pb$ collisions at unprecedented high energies of $\sqrt{s} = 7$ TeV and $\sqrt{\mathrm{s}_{_{\mathrm{NN}}}} = 2.76$ TeV, respectively, as provided by the Large Hadron Collider. Open charmed hadrons are kinematically fully reconstructed in the hadronic decay channels $D^0\rightarrow K^-\pi^+$, $D^+\rightarrow K^-\pi^+ \pi^+$, and $D^{*+} \rightarrow D^0 (K^-\pi^+) + \pi^+$ and identified through their secondary decay-vertex topology. Inclusive charm and beauty production is measured by detecting electrons (muons) from semileptonic decays of open charmed and beauty hadrons in the central (forward) region. First results on nuclear modifications factors in $Pb-Pb$ collisions from hadronic and semi-leptonic decays are presented. Comparison to results from state-of-the-art QCD calculations is given.
