Brussels/Geneva, 28 May 2013. The European Commission and CERN have today agreed to support the construction of SESAME (Synchrotron-light for Experimental Science and Applications in the Middle East), one of the most ambitious research facilities in the Middle East.

An international team of physicists at the radioactive-beam facility ISOLDE at CERN1 have for the first time measured the ionization potential of the rare radioactive element astatine2.
The value for astatine, published today in the journal Nature Communications, could help chemists to develop applications for the element in radiotherapy, and will serve as a benchmark for theories that predict the structure of super-heavy elements.
On 2 June 2013 CERN1, in collaboration with its local partners, will be inaugurating a scientific tourist trail through the Pays de Gex and the Canton of Geneva known as the Passport to the Big Bang. A major programme of activities has been organised for the general public at various CERN sites, including special events and bike rides.
Geneva, 8 May 2013. An international team at the ISOLDE radioactive-beam facility at CERN1 has shown that some atomic nuclei can assume asymmetric, "pear" shapes. The observations contradict some existing nuclear theories and will require others to be amended. The results are published in the journal Nature on 8 May 2013.
Geneva, 30 April 2013. The ALPHA collaboration at CERN1 has published a paper in Nature Communications describing the first direct analysis of how antimatter is affected by gravity.
ALPHA was the first experiment to trap atoms of antihydrogen — neutral antimatter atoms held in place with a strong magnetic field for up to 1000 seconds. The original goal of the experiment was not to study gravity, but the researchers realised that the data they had already collected might be sensitive to gravitational effects.
