<b>ABSTRACT</b><br>
<br>
The theory of the strong interaction, quantum-chromodynamics,
predicts for high temperature and density a new state of matter in
which the confinement of quarks and gluons is lifted. This state,
the quark-gluon plasma, existed in the early universe after the
electro-weak phase transition up to about 10 microseconds. In the
past 25 years, accelerator-based experiments have been conducted in
order to recreate this state of matter for a short time. The ideal
tool is collisions of heavy nuclei at energies as high as possible.
Now with the Large Hadron Collider (LHC) at CERN, an entirely new
energy regime is accessible. Since November 2010, collisions of lead
nuclei at the LHC have been studied in three experiments. In this
talk, selected first results from the ALICE experiment will be
presented and discussed in the context of results at lower beam
energies and theoretical interpretation. <br>
