It is well known that superconductors display a mechanism similar to the Brout–Englert–Higgs mechanism in the Standard Model, and now a condensed-matter analogue of the Higgs boson itself has been found. Ryusuke Matsunaga of the […]
Sodium gas ionization Collecting electrons The range of beam detectors at the ISR has been increased by the installation of a novel beam-profile detector, which observes the ionization caused in a sodium curtain through which the beam […]
One of my most memorable experiences of CERN is from an early morning in the summer of 1966. I drove to CERN with my two small children, one and three years of age, to fetch […]

Optical Surfaces supply high-precision toroidal mirrors (toroids) made to exact specifications. Toroidal mirrors are normally used where a beam needs to be focused or folded. The design of toroidal mirrors eliminates astigmatism normally caused by […]

Reporting from a meeting to honour a surprising discovery.
A selection of highlights from events surrounding the official 60th birthday.
Plenty of news as ICHEP visited Spain for the first time.
Highlights from results presented at Beauty 2014.
The Brookhaven muon storage ring is being reassembled at Fermilab.
Delicate galaxy This delicate galaxy pictured by the NASA/ESA Hubble Space Telescope is a nice example of a nearby, recently formed galaxy. Galaxies in our cosmic neighbourhood are usually mature, with a mix of stars formed at […]
Galactic hemispheres The Planck collaboration has published an all-sky map of the polarized thermal emission of dust grains in the Milky Way. It shows that the field used by the experiment for Background Imaging of Cosmic Extragalactic […]
Signal propagation in neurons has long been modelled as an electrochemical pulse, or “action potential”, according to the textbook Hodgkin–Huxley model. Now, Thomas Heimburg and colleagues at the Niels Bohr Institute in Copenhagen have shown […]
The SESAME building A key accelerator at the Synchrotron-light for Experimental Science and Applications in the Middle East (SESAME) facility in Allan, Jordan, has reached its top energy recently. After having successfully stored electrons in the Booster-Synchrotron in […]
One of the most striking features of living matter is that sugars all seem to be right-handed and amino acids left-handed. One resolution to the puzzle is the Vester-Ulbricht hypothesis, which is that chiral β-decay […]
Many people probably owe a significant part of their productivity to caffeine, from coffee, tea, or chocolate. So does this caffeine share a common origin? Victor Albert of the University of Buffalo in New York […]
Sea-floor map Using radar altimetry data from two satellites – CryoSat-2 from the European Space Agency and Jason-1 from NASA and the French Centre National d’Etudes Spatiales – David Sandwell of the Scripps Oceanographic Institute in La […]
Sugar best after all? Sugar substitutes might affect bacteria in the gut in such a way as to exacerbate metabolic disorders. Eran Elinav of the Weizmann Institute of Science in Rehovot and colleagues have found that mice given water […]
SESAME accélère des électrons à 800 MeV AMS trouve des indices de nouvelles sources de positons dans les rayons cosmiques Les faisceaux sont de retour dans le Décélérateur d’antiprotons Les promesses des topologies ” boostées “ La mesure de l’angle γ s’affine grâce aux résultats de LHCb Produire le charme avec de la lumière ATLAS observe et mesure la désintégration H → WW Les neutrinos pour mieux comprendre la production cohérente de pions Les cathodes à nanotubes sources de faisceaux intenses d’électrons Excellent départ pour la collaboration FCC Les édulcorants pas si anodins La collaboration Planck confirme les doutes sur les résultats de BICEP2
On 9–10 September, representatives of about 70 institutes worldwide met at CERN to establish the International Collaboration Board (ICB) at the Future Circular Collider (FCC) study. The study covers the designs of a 100-TeV hadron collider and […]
New cathode It looks like a small black button, but in tests at Fermilab’s High-Brightness Electron Source Lab it has produced beam currents 103–106 times greater than those generated with a large laser system. Designed by a collaboration […]
Experiments at Fermilab are advancing an intriguing story that began three decades ago, with investigations of coherent neutrino interactions that produce pions yet leave the target nucleus unscathed. Fig. 1. When neutrinos scatter coherently off an entire […]
The WW final state was a key component in the discovery of the Higgs boson with a mass of around 125 GeV, and remains essential for the ongoing measurements of the particle’s properties. Now, the ATLAS […]
The electric charge of lead ions, when accelerated to ultra-relativistic velocities, is the source of an intense flux of high-energy quasi-real photons. Ultra-peripheral collisions – the interaction of a photon with a target at impact […]
For the first time in a single experiment, LHCb has achieved a precision of better than 10° in measuring the angle γ that is linked to CP violation in the Standard Model. Confidence-level curve In the celebrated […]
While analyses are progressing to ascertain the consistency of the new boson discovered at the LHC with the Standard Model Higgs boson (H), the LHC collaborations continue to develop tools in their search for new […]
Antiprotons returned Antiprotons returned to CERN’s Antiproton Decelerator (AD) on 5 August and experiments have been receiving beams since mid-September, following an intensive consolidation programme during the first long shutdown (LS1) of the accelerator complex. Work has involved […]
Fig. 1. The Alpha Magnetic Spectrometer (AMS) on the International Space Station (ISS) has new results on energetic cosmic-ray electrons and positrons, based on analysis of the first 41 billion events. These results provide a deeper understanding […]
