Workshop participants The LHC Performance Workshop took place in Chamonix from 25 to 28 January. Attended by representatives from across the accelerator sector, including members of the CERN Machine Advisory Committee, and the LHC experiments, the programme covered […]
Tests of local realism based on Bell’s inequality have, up to now, always had a small loophole, but that has now been closed. Lynden K Shalm of NIST in Boulder, Colorado, US, and colleagues looked at […]
Chameleons are able to lash out with their sticky tongues that extend more than twice their body lengths, and achieve incredible accelerations of 25490 m/s2 or 264 g, corresponding to peak power outputs of more than […]
Predicted ninth-planet orbit Pluto was considered to be the ninth planet of the solar system, until it was relegated to a “dwarf planet” by the International Astronomical Union (IAU) in 2006. It was judged to be too small […]
Ceres crater This impressive crater is located on Ceres, the largest object in the asteroid belt between Mars and Jupiter. With a diameter of 950 km, Ceres has been considered, since 2006, a “dwarf planet”, as Pluto. And, […]
The laboratory takes on the challenges of the coming years.
Go-ahead to prepare a Comprehensive Design Report is received.
Take a virtual tour of ESO’s breathtaking installation.
Sonograms can be used to better understand human motor control.
Future promise Over the next five years, key events shaping the future of particle physics will unfold. We will have results from the second run of the LHC, and from other particle and astroparticle physics projects around […]

Hydrogen and deuterium are, chemically, quite similar, but without their electrons, a proton is less than half the radius of a deuteron. M Lozada Hidalgo and colleagues of the University of Manchester in the UK used […]
We all think that electric charge is conserved, but physics is an experimental subject, so it’s always good to check. The Borexino collaboration has now used a liquid scintillation detector to search for the decay […]
Early life was unicellular, and we now know that it took just one random but crucial mutation, 600 million years ago, which changed the function of one key protein, to make multicellular life possible. In multicellular […]
Ca isotopes studied at ISOLDE Magic numbers appear in nuclei in which protons or neutrons completely fill a shell. The existence of magic numbers to explain certain regularities observed in nuclei was discovered in 1949 independently by M Goeppert-Mayer and J D Jensen, […]
The ALPHA experiment The ALPHA collaboration has just published a new measurement of the charge of the antihydrogen atom. Although the Standard Model predicts that antihydrogen must be strictly neutral, only a few actual direct measurements have been […]
As the LHC delivered proton–proton collisions at the record energy of 13 TeV during the summer and autumn of last year, the experiments were eagerly scrutinising the new data. They were on alert for the signatures […]
The LHC Run 1, famed for its discovery of the Higgs boson, came to a conclusion on Valentine’s Day (14 February) 2013. The little-known fact is that the last three days of the run were reserved neither […]
High-energy scattering of partons (quarks and gluons) produces collimated cones of particles called jets, the production rate of which can be calculated using perturbative QCD techniques. In heavy-ion collisions, partons lose energy in the hot, […]
Owing to the large cross-section for charm production at the LHC, LHCb collected the world’s largest sample of charmed hadrons, allowing for stringent tests of the Cabibbo–Kobayashi–Maskawa (CKM) mechanism in the Standard Model (SM). The […]
The DAMPE detector On 17 December, the Chinese Academy of Sciences (CAS) successfully launched the DArk Matter Particle Explorer (DAMPE) satellite from the Jiuquan Satellite Launch Center in northwest China, marking the entrance of a new player in the […]

Synthetic diamond A novel, new form of carbon, dubbed “Q-carbon”, is harder than diamond. The new phase, discovered by Jagdish Narayan and Anagh Bhaumik of North Carolina State University in Raleigh, US, results from the rapid quenching […]
Four new elements have been discovered, completing the seventh row of the periodic table. The RIKEN collaboration in Japan takes the credit for element 113 (ununtrium, Uut), and they will be invited to propose a […]
