“Stable beams” At the beginning of May, the LHC declared the start of a new physics season for its experiments. The “Stable Beams” visible on the LHC Page 1 screen (see image above) is the “go ahead” for […]
Clouds surround galactic centre The High Energy Stereoscopic System (HESS) – an array of Cherenkov telescopes in Namibia – has detected gamma-ray emission from the central region of the Milky Way at energies never reached before. The likely source […]
Complex collision events challenge computing requirements.
Taking on the challenge of preserving “digital memory”.
The experiment is fully in the data-taking period.
Algorithm aims to identify and fully reconstruct particles.
The world’s largest cosmic-ray experiment, the Pierre Auger Observatory, is embarking on its next phase, named AugerPrime.
Building 40 Our world has been transformed almost beyond recognition since CERN was founded in 1954. Particle physics has evolved to become a field that is increasingly planned and co-ordinated around the world. Collaboration across regions is […]

Tired of poor battery life? May Le Thai and colleagues of the University of Irvine in California have good news. Nanowire capacitors made from manganese-dioxide nanowires coated with a PMMA gel electrolyte can bend to […]
A novel approach to detecting low-frequency gravitational waves in the 0.1–10 Hz band uses the entire Earth as a detector. Francesco Mulgaria and Alexander Kamenshchik of the University of Bologna, Italy, calculate that the more than […]
Some plants exude a sweet nectar when their leaves are wounded, and now we know why. Anke Steppuhn of the Free University of Berlin and collaborators studied injuries to the bittersweet nightshade (Solanum dulcamara) and […]
After a short, but intense, “intermezzo” as editor of the CERN Courier, I’m stepping down as I head off to new challenges. I would like to thank the CERN Courier Advisory Board and the many […]
With the increase in the centre-of-mass energy provided by the Run 2 LHC collisions, the production cross-sections of many new-physics processes are predicted to rise dramatically compared with Run 1, in contrast to those of the background […]
Eighty physicists gathered in Manchester on 6 and 7 April to discuss the future of the LHCb experiment. The LHCb collaboration is currently constructing a significant upgrade to its detector, which will be installed in 2019/2020. […]
Astrophysics and cosmology have established that about 80% of the mass in the universe consists of dark matter. Dark matter and normal matter interact gravitationally, and they may also interact weakly, raising the possibility that […]
In April, the MoEDAL collaboration submitted its first physics-research publication on the search for magnetic monopoles utilising a 160 kg prototype MoEDAL trapping detector exposed to 0.75 fb–1 of 8 TeV pp collisions, which was subsequently removed and […]
Fig. 1. A new luminosity record at the charm-tau energy region was recently broken again by the Beijing Electron–Positron Collider (BEPCII). The new record, 1 × 1033 cm–2s–1 at 1.89 GeV beam energy, is also the design luminosity for this collider […]

Humans surpass machines Quantum mechanics is usually considered to be counter-intuitive for humans but, remarkably, video games, which correspond to quantum problems, show that we actually do very well. Jacob F Sherson and colleagues at the University of Aarhus […]
Sleeping phases Many animals are known to sleep in some form or another. The brain activities during sleep such as slow-wave (SW) or rapid-eye movement (REM) had, however, only been seen in birds and mammals, suggesting that […]
The NOvA collaboration has measured the oscillation probability of muon neutrinos into electron neutrinos at the first oscillation maximum. The probability is proportional to sin2(2θ13), which has been well measured by reactor experiments. In an […]
A typical white dwarf has a helium and hydrogen outer layer covering a core of carbon and oxygen produced from burning helium. Now, S O Kepler of the Universidade Federal do Rio Grande do Sul in Porto […]
Scanning tables at CERN MILADY scanning tables Photographs of tracks made by high-energy charged particles passing through a bubble chamber constitute one of our most direct means to access the sub-nuclear world. No other detection technique gives such […]
