The Universe’s extra bits

Parallel universes, unknown forms of matter, extra dimensions….This is not cheap science fiction but very concrete physics theories that the scientists are trying to confirm with the LHC and other ongoing experiments. Although it's enough to make us dream about going to a parallel world for the weekend, let’s keep our feet firmly on the ground and try to work out what all these things really are… >>

Scientific Opportunity: the Tevatron and the LHC

The press makes much of the competition between CERN’s LHC and Fermilab’s Tevatron in the search for the Higgs boson. This competitive aspect is real, and probably adds spice to the scientific exploration, but for us such reporting often feels like spilling the entire pepper shaker over a fine meal. The media’s emphasis on competition obscures the more important substance of our long-standing collaboration in scientific discovery. >>

The latest from the LHC

The setting-up to prepare the LHC for running with nominal ramp rates and with bunch trains instead of single-bunch injection have continued over the last two weeks. The goal is to reduce the machine filling time and increase its luminosity. Running with bunch trains requires the careful setting-up of crossing angles in order to avoid unwanted collisions on either side of the experiments. >>

Art in the countryside…with a taste of science

Between 13 July and 15 August, the second edition of the Art en Campagne exhibition took place in the countryside of the Pays de Gex and across the French-Swiss border. Works from around twenty artists were exhibited at various locations in the municipalities of Ornex (F), Versonnex (F) and Collex-Bossy (CH). The exhibition was not dedicated to science but, on closer inspection… >>

A strange journey

CERN has certainly had plenty written about it over the years but who would have thought that it would one day be the subject of a dark comic book? That's just what's happened, though, with the publication of "Sous-sol" by two cartoonists from Geneva, Pierre Wasem and Tom Tirabosco. >>

The European hadron therapy community touches base

The European hadron therapy community gathered in Stockholm from 3 to 5 September for the annual ENLIGHT workshops. Three of the four EC-funded projects born under the umbrella of ENLIGHT (see box) were discussed in the prestigious Nobel Forum at the Karolinska Institutet. >>

Textbook tests with tungsten

CERN's linear collider detector group joins forces with CALICE in building the world's first tungsten hadronic calorimeter. >>

The European Graduate Course in Cryogenics hosted at CERN.

The “liquid helium” week of the European Graduate Course in Cryogenics was held at CERN from 30 August to 3 September 2010. This course scheduled annually since 2008 is a common teaching project of the Universities of Technology of Dresden, Wroclaw and Trondheim. It is focused on liquid natural gas, hydrogen and helium cryogenics. Attending students were carefully selected, and will take an examination giving ECTS credits for their academic curriculum. >>
