A ceremony at CERN on 15 June celebrated the start of civil-engineering works for the high-luminosity upgrade of the Large Hadron Collider (HL-LHC). The upgrade will allow about 10 times more data to be accumulated by […]

Muons have been accelerated by a radio-frequency accelerator for the first time, in an experiment performed at the Japan Proton Accelerator Research Complex (J-PARC) in Tokai, Japan. The work paves the way for a compact […]

On 2 May, the Thomas Jefferson National Accelerator Facility in Virginia, US, celebrated the completion of the 12 GeV CEBAF upgrade project. The $338 million upgrade has tripled CEBAF’s original operating energy and will allow, among other […]

A new facility called the Higgs Centre for Innovation opened at the Royal Observatory in Edinburgh on 25 May as part of the UK government’s efforts to boost productivity and innovation. The centre, named after Peter […]

On 28 May, the world’s largest and most sensitive detector for direct searches of dark matter in the form of weakly interacting massive particles (WIMPs) released its latest results. XENON1T, a 3D-imaging liquid-xenon time projection […]

CERN’s radioactive ion-beam facility ISOLDE has stamped a new coin in its impressive collection. Long considered the domain of high-energy, in-flight rare-isotope facilities, chromium has now been produced at ISOLDE in prodigious quantities, thanks to […]

Bottomonium mesons, composed of beauty quark–antiquark pairs bound to each other through the strong force, play a special role in our understanding of hadron formation because the large quark mass allows important simplifications in the […]

Last year, the LHCb collaboration announced the first observation of the Ξcc++ baryon, a doubly charmed particle (CERN Courier July/August 2017 p8). It was identified via the decay Ξcc++ → Λc+ K–π+π+, with the Λc+ baryon subsequently […]

One of the key goals in exploring the properties of QCD matter is to determine the minimum value of the shear viscosity to entropy density ratio (η/s) for an ideal fluid. In heavy-ion collisions at […]

Rhinoviruses (RVs), far from being just a seasonal nuisance causing common colds, can also lead to serious complications in conditions such as asthma and cystic fibrosis. The huge diversity of RVs precludes the development of […]

Quantum computing, which exploits quantum phenomena such as entanglement and superposition, is rapidly gaining ground. Now, Eugene Dumitrescu from Oak Ridge National Laboratory in Tennessee and colleagues have used quantum machines to calculate the binding […]

Conventional thinking has it that ice is slippery due to a thin film of liquid water created by actual melting or the pressure of objects such as skate blades. Using molecular dynamics simulations of the […]

The collective dynamics of fish schooling has traditionally been approached using simple behavioural rules, with little consideration of the flow of water induced by the fish. Audrey Filella of Aix-Marseille University in France and colleagues […]

Biohybrid robots, which are based on heart or skeletal muscle tissue formed on flexible substrates, have suffered from poor agility and durability owing to tissue shrinkage and loss of function. Now, taking a cue from […]

Artificial neural networks may get a huge boost from analogue memory. Much of the time and energy that goes into training such networks is due to the need to transfer weight data between conventional digital […]

For decades, theoretical models of galaxy evolution have predicted that the supermassive black hole lying at the heart of the Milky Way is surrounded by thousands of smaller black holes left behind by dying stars. […]

The second data release of the Gaia collaboration on 25 April resulted in this extremely detailed image of the sky, which contains nearly 1.7 billion stars. The data comprise information on the position of these stars […]

The recent demonstration of muon ionisation-cooling by the MICE collaboration opens a path to a neutrino factory and muon collider.

The Yandex machine-learning school for high-energy physics is teaming up with experiments at CERN and beyond to train young researchers in the arts of deep learning.

Data from the ATLAS experiment is a key element in HALO, an important new commission undertaken for Art Basel, the world’s premier fair for contemporary art. It’s the latest exciting outcome of Arts at CERN, which has become a major player in the world where art and science meet.
