“If you have an apple and I have an apple and we exchange these apples then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange these ideas, then each of us will have two ideas”. (George Bernard Shaw). The CERN Global Network is a new, ideal place for past and present members of the CERN community to share ideas and create new links.

This week, CERN is launching the CERN Global Network, which responds to a real need for us to keep in touch, to share our knowledge and expertise, and to build on the fantastic resource of the CERN community broadly defined.

After just a few weeks of running, the LHC has already provided the experiments with millions of high-energy collisions. Physicists from all over the world are analysing the new data and retracing the particles discovered in past experiments. The W particle, discovered in 1983 by the UA1 and UA2 experiments at CERN, and the B-meson, discovered in 1977 by the E288 experiment at Fermilab, have recently popped up amongst the rich harvest of information.

Last weekend saw a record physics fill with a tenfold increase in instantaneous luminosity (event rate from collisions), marking an important milestone for the LHC. This physics fill did not only establish luminosities above 1.1 x 1028 cm-2 s-1 in all four experiments but was also kept in "stable beam" mode for a new record length of 30 hours. The particle physics experiments were able to more than double the total number of events so far recorded at 3.5 TeV.

Today, printed circuit boards – PCBs - are part and parcel of our everyday lives. We find them everywhere: in our computers, mobile phones, food processors, cars, radios, remote controls, etc. Although the associated technology no longer holds any secrets for us, its uses don't end here. Olivier Pizzirusso and his team are using the techniques involved in PCB manufacture to build the particle detectors of the future.

About 96% of the Universe is in the form of unknown matter and energy. The rest – only 4% – is the ‘ordinary matter’ that we are made of and that makes up all the planets, the stars and the galaxies we observe. The LHC experiments have the potential to discover new particles that could make up a large fraction of the Universe.

The International Technical Safety Forum is a meeting of safety experts from several physics labs in Europe and the US. Since 1998 participants have been meeting every couple of years to discuss common challenges in safety matters. The Forum helps them define best practices and learn from the important lessons learned by others.

On Friday 23 April, 225 primary school children from the eight schools in Meyrin-Cointrin and their accompanying adults took part in a big game of Ethnopoly. Private individuals, associations, administrations, shopkeepers and CERN all opened their doors to them to talk about their countries, their customs and what they are doing to promote tolerance and integration.
