Particle physicists thrive on information. They first create information by performing experiments or elaborating theoretical conjectures and then they share it through publications and various web tools. The INSPIRE service, just released, will bring state of the art information retrieval to the fingertips of researchers.

A couple of weeks into the LHC’s first high energy physics run, and we’ve already got an impressive story to tell. Long fills for physics are becoming routine, luminosity scans have increased the collision rate. The operators are becoming adept at squeezing the beams ever smaller, and higher intensity studies are progressing well. With the experiments, it’s the same story.

Following the great success of the first 3.5 TeV collisions in all four LHC experiments on 30 March, the focus of the LHC commissioning teams has turned to consolidating the beam injection and acceleration procedures.

With its high discovery potential and unprecedented performance, the LHC is a much-anticipated machine. Media and the public are eagerly following every development, and on 30 March, the communication teams provided wide coverage of the day’s historic events.

CERN’s poplars were planted 50 years ago to soak up the surplus water in the ground beneath the Laboratory’s sites. Now that they have reached the end of their life-cycle, some of the poplars are in danger of falling or losing their dead branches. On Saturday, 17 April, as part of the campaign launched in February at Prévessin, work will start on replacing the poplars on central areas of the Meyrin site.

For many years, the absence of antimatter in the Universe has tantalised particle physicists and cosmologists: while the Big Bang should have created equal amounts of matter and antimatter, we do not observe any primordial antimatter today. Where has it gone? The LHC experiments have the potential to unveil natural processes that could hold the key to solving this paradox.

On 11 March, Lyn Evans, the LHC project leader, talked live to hundreds of students in Wales using the standard videoconference equipment available at CERN (see box below). The students were delighted with the presentation and obviously very much appreciated this modern means of communication with the Laboratory. A further lecture is planned for May.

Four million black and white copies and twenty thousand colour copies in 2009 alone – all printed, finished and filed by one person: Florella Lamole, an employee of an outside contractor who has been based at CERN since 1982.

Graham Farmelo, author and former particle physicist, visited CERN on 25 March. To the CERNois gathered in the Main Auditorium, he talked about his new book The Strangest Man, a biography of Paul Dirac. Dirac was obsessed by the importance of mathematical beauty in fundamental physics, a belief that was “almost a religion” to him. Farmelo himself has no doubts: among all of the natural phenomena the LHC may unveil, supersymmetry is the most beautiful.

On 25 March, a fire drill was carried out in Building 60 in the presence of the Director-General. The dual aims were to test the alarm system and give the building's occupants the opportunity to practice the evacuation drill. Everything went well and people were able to resume their normal activities immediately afterwards.
