CERN experiment sheds new light on cloud formation

Geneva, 16 May 2014. In a paper published in the journal Science today, CERN1’s CLOUD2 experiment has shown that biogenic vapours emitted by trees and oxidised in the atmosphere have a significant impact on the formation of clouds, thus helping to cool the planet. These biogenic aerosols are what give forests seen from afar their characteristic blue haze. The CLOUD study shows that the oxidised biogenic vapours bind with sulphuric acid to form embryonic particles which can then grow to become the seeds on which cloud droplets can form.

The Third Collide@CERN-Geneva prize in Music and Sound awarded to two artists

Geneva, 29 April 2014. CERN1, the City and the Canton of Geneva have awarded the third Collide @ CERN-Geneva prize2 jointly for the first time to two artists - the guitarist Vincent Hanni3 who is a member of the band The Young Gods and the installation artist Rudy Decelière4.

The award was made for their detailed proposal to explore in sound how the analogue developed into the digital world at CERN, which this year celebrates its 60th anniversary.

International team of LHC and Tevatron scientists announces first joint result

Chicago, USA and Geneva, Switzerland, 19 March 2014. Scientists working on the world’s leading particle collider experiments have joined forces, combined their data and produced the first joint result from Fermilab1’s Tevatron and CERN2’s Large Hadron Collider (LHC), past and current holders of the record for most powerful particle collider on Earth. Scientists from the four experiments involved—ATLAS, CDF, CMS and DZero—announced their joint findings on the mass of the top quark today at the Rencontres de Moriond international physics conference in Italy.

CERN celebrates 60 years of science for peace

Geneva, 18 March 2014. CERN1 is celebrating 60 years of science for peace in 2014, with events at the Organization’s Geneva laboratory and in its Members States. Festivities will focus on two key events. The first is on 1 July at UNESCO Headquarters in Paris, where the Organization’s 12 founding members established the CERN Convention on 1 July 1953. The second marks CERN’s 60th birthday, 29 September, the date on which the Convention was ratified 60 years ago and the Organization formally came into existence. It will be celebrated in Geneva.

10th edition of the International Masterclasses in Particle Physics to attract more than 10,000 high-school students worldwide

Geneva, 10 March 2014. Each year in spring, research institutes and universities around the world invite students and their teachers for a day-long programme to experience life at the forefront of basic research. These International Masterclasses give students the opportunity to be particle physicists for a day by analysing real data from CERN1’s Large Hadron Collider, the LHC.

CERN prepares its long-term future

Geneva, 6 February 2014. Particle physics takes the long-term view. Originally conceived in the 1980s, the LHC took another 25 years to come into being. This accelerator, which is unlike any other, is just at the start of a programme which is expected to run for another 20 years. Even now, as consolidation work aimed at a restart in 2015 continues, detailed plans are being hatched for a large-scale upgrade to increase luminosity and thereby exploit the LHC to its full potential.

CERN experiment produces first beam of antihydrogen atoms for hyperfine study

Geneva, 21 January 2014. The ASACUSA1 experiment at CERN2 has succeeded for the first time in producing a beam of antihydrogen atoms. In a paper published today in Nature Communications, the ASACUSA collaboration reports the unambiguous detection of 80 antihydrogen atoms 2.7 metres downstream of their production, where the perturbing influence of the magnetic fields used initially to produce the antiatoms is small. This result is a significant step towards precise hyperfine spectroscopy of antihydrogen atoms.
