Geneva, 28 July 2011. In a paper published today in the journal Nature, the Japanese-European ASACUSA experiment at CERN1 reported a new measurement of the antiproton’s mass accurate to about one part in a billion. Precision measurements of the antiproton mass provide an important way to investigate nature’s apparent preference for matter over antimatter.

Geneva, 21 July 2011. The first of the major summer conferences for particle physics opens today in Grenoble. All of the LHC experiments will be presenting results, and a press conference is scheduled for Monday 25 July. The conference follows an extremely successful start to LHC running in 2011, and results are eagerly awaited.
Geneva, 7 July 2011. Four months after launching the alpha version, CERN1 has today issued version 1.1 of the Open Hardware Licence (OHL), a legal framework to facilitate knowledge exchange across the electronic design community.
Geneva, 24 June 2011. At its 159th session this week, the CERN1 Council congratulated CERN on the excellent performance of the LHC, and welcomed the news that formal confirmation has been received from the five countries applying for CERN Membership.
Geneva, 17 June 2011. Today at around 10:50 CEST, the amount of data accumulated by LHC experiments ATLAS and CMS clicked over from 0.999 to 1 inverse femtobarn, signalling an important milestone in the experiments' quest for new physics. The number signifies a quantity physicists call integrated luminosity, which is a measure of the total number of collisions produced. One inverse femtobarn equates to around 70 million million1 collisions, and in 2010 it was the target set for the 2011 run.
