J apan IPMU joins the Kavli family of institutes The University of Tokyo has announced the establishment of an endowment by the Kavli Foundation for the Institute for the Physics and Mathematics of the Universe (IPMU). The institute, which will now be known as the Kavli IPMU, probes the mysteries of modern cosmology through collaborative research conducted by a range of scientists, including mathematicians, theoretical physicists, experimental physicists and astronomers. Together they focus on topics such as dark matter, dark energy and the possibility of a single unified theory that can explain the cosmos at the smallest and largest scales.

On 15 February, Helge Reinhold Braun, left, parliamentary state secretary, federal ministry of education and research (BMBF), of the Federal Republic of Germany, was welcomed to CERN by the director-general, Rolf Heuer (here demonstrating the temperature-sensitive coffee mug that depicts the history of the universe). Braun toured the ATLAS underground experimental area and visitor centre, as well as the LHC tunnel, before meeting German staff at CERN.

Murray Gell-Mann, well known for proposing the quark model and as a recipient of the Nobel Prize in Physics in 1969, came to CERN on 23 January. During his visit he gave a theoretical physics seminar on decoherent histories in quantum mechanics. He also toured ATLAS – where he is seen here – and CMS. (For an interview with Gell-Mann, see http://cdsweb.cern. ch/record/1421671.)
