A new record has been set in squeezing of the quantum state of light, which could be important for improving the sensitivity of gravitational-wave detectors and for more precise calibrations of photoelectric detectors. Henning Vahlbruch […]
Computers Stock of tapes After a running-in period which was expected to last about a year, the new central computer, the CDC 7600, can now handle more work than all the other computers at CERN put together. A sector […]

CERN’s S’Cool LAB students As far back as 1939, the US educator Abraham Flexner penned a stirring paean to basic research in Harper’s Magazine under the title “The usefulness of useless knowledge.” Flexner, perhaps being intentionally provocative, pointed out […]

This article has been supplied by Buckley Systems. General Buckley Systems manufactures sophisticated magnets, and it is certified ISO 9001:2008 for the following scope: the design and manufacture of precision electromagnets, ion-beam physics hardware, and […]
Interview with Kip Thorne, who predicted LIGO’s observation of gravitational waves.
A new study group will investigate novel use of CERN’s accelerator complex to target fundamental-physics questions.
Compact Linear Collider focuses on an optimised initial-energy stage at 380 GeV.
Advanced scintillating materials have found their way into novel detectors for physics and medicine.
Ahuna Mons This impressive alien view shows the mountain Ahuna Mons rising behind an impact crater on the dwarf-planet Ceres, which is the largest body among the thousands of asteroids that are located between the orbits of […]
Stars in the first Gaia catalogue The largest all-sky survey of celestial objects has been compiled by ESA’s Gaia mission. On 13 September, 1000 days after the satellite’s launch, the Gaia team published a preliminary catalogue of more than a billion […]
Model quadrupole magnet On 19 September, the European Investment Bank (EIB) signed a 250 million Swiss francs (€230 million) credit facility with CERN in order to finance the High-Luminosity Large Hadron Collider (HL-LHC) project. The finance contract follows […]
The atmosphere–ocean system can drive the Earth to produce seismic signals called “microseisms”. These can be produced by large slow-moving storms but also by smaller storms, and in particular small extratropical storms dubbed “weather bombs”, […]
An analogue of the Hawking effect, whereby black-body radiation is emitted by black holes, can be seen in general wave phenomena when analogue horizons are present as waves propagating on a stationary counter-flowing medium. When […]
Copper-wire ghost images Ghost imaging constructs images of objects using information from light detected at two detectors. The idea is to use correlations in intensities between an object beam that strikes the object and a reference beam that […]
Beer insight Humans have a long relationship with the yeasts that make beer. Genetic and phenotypic analysis of 157 strains of Saccharomyces cerevisiae yeast used by the fermentation industry now reveal that they all originate from a […]
Tous les systèmes se préparent pour le LHC à haute luminosité La physique commence à HIE-ISOLDE Trois ans de plus pour l’initiative sur le libre accès LUX-ZEPLIN franchit une nouvelle étape Des faisceaux plus grands pour explorer les petits angles avec le LHC ATLAS vise les couplages Higgs-quark CMS étudie la largeur du quark top LHCb s’intéresse à une nouvelle source de violation de CP ALICE examine la viscosité de cisaillement dans la matière CDQ La bière influence l’évolution de la levure Gaia réalise le plus grand recensement stellaire à ce jour
One of the key goals in exploring the properties of QCD matter is to pin down the temperature dependence of the shear-viscosity to entropy-density ratio (η/s). In the limit of a weakly interacting gas, kinetic […]
The LHCb collaboration presented new results at the 8th International Workshop on Charm Physics (Charm 2016), which took place in Bologna on 5 to 9 September. Among various novelties, the collaboration reported the most precise […]
Twenty years after its discovery at the Tevatron collider at Fermilab, interest in studying the top quark at the LHC is higher than ever. This was illustrated by the plethora of new results presented by […]
The Higgs boson has been observed via its decays to photons, tau leptons, and Z and W bosons, which has allowed ATLAS to glean much information about the particle’s properties. So far, these properties agree […]
Roman Pots Usually, the motto of the LHC operations team is “maximum luminosity”. For a few days per year, however, this motto is put aside to run the machine at very low luminosity. The aim is to […]
Detector TPC core A next-generation dark-matter detector in the US called LUX-ZEPLIN (LZ), which will be at least 100 times more sensitive than its predecessor, is on schedule to begin its deep-underground hunt for WIMPs in 2020. In […]
Freely available research results In September, following three years of successful operation and growth, CERN announced the continuation of the global SCOAP3 open-access initiative for at least three more years. SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle […]
HIE-ISOLDE cryomodules In early September, the first physics experiment using radioactive beams from the newly upgraded ISOLDE facility got under way: a study of tin, which is a special element because it has two double magic isotopes. […]
