Splice inspection When the shift crew in the CERN Control Centre extracted the beams from the LHC on 14 February last year, it marked the beginning of the first long shutdown, LS1, not only for the LHC but […]
The spiral galaxy ES0 137-001 This new image by the Hubble Space Telescope shows the spiral galaxy ESO 137-001, framed against a bright background as it moves through the heart of the Norma cluster of galaxies. The image captures not only […]

The 1980s were characterized by two outstanding achievements that were to influence the long-term future of CERN. First came the discovery of the W and Z particles, the carriers of the weak force, produced in proton–antiproton collisions […]
Gamma-ray emission A new analysis of observations of the galactic centre by the Fermi Gamma-ray Space Telescope strengthens the case for a signal from annihilating dark matter. The authors claim that the excess emission has a spectral […]
Artificial muscle fibre A new type of artificial muscle made from fishing line and sewing thread dramatically outperforms predecessors. Carter S Haines of the University of Texas at Dallas and colleagues have shown how inexpensive, high-strength polymer fibres used […]
Sound transmission is usually reciprocal – if you want to listen to someone you have to let them be able to hear you. Now, Romain Fleury of the University of Texas at Austin and colleagues […]
Discriminant distribution Data from the CDF and D0 experiments at the Tevatron have revealed one of the rarest methods of producing a top quark. The two collaborations announced jointly on 21 February that they have observed s-channel production […]
While it is now generally accepted that dark matter makes up the majority of the mass in the universe, little is known about what it is. A favoured hypothesis among particle physicists has long been […]
The Standard Model predicts that the photons emitted in b → sγ transitions, which can only occur through loop-level processes, are predominantly left-handed. This means that the asymmetry between the amplitudes with right- and left-handed photons – […]
The fusion of two weak bosons is an important process that can be used to probe the electroweak sector of the Standard Model. Measurements of Higgs production via weak-boson fusion are crucial for precise extraction […]
As the LHC experiments improve the precision of their measurements of Standard Model processes, the extent of possibilities for new physics open to exploration is becoming ever more apparent. Even within a constrained framework for […]
The Arcturus Laser The field of laser-induced relativistic plasmas and, in particular, laser-driven particle acceleration, has undergone impressive progress in recent years. Despite many advances in understanding fundamental physical phenomena, one unexplored issue is how the particle spins […]
First interactions On 11 February, the NOvA collaboration announced the detection of the first neutrinos in the long-baseline experiment’s far detector in northern Minnesota. The neutrino beam is generated at Fermilab and sent 800 km through the Earth’s surface […]
Knowledge of the electron mass has been improved by a factor of 13, thanks to a clever extension of previous Penning-trap experiments. A team from the Max-Planck-Institut für Kernphysik in Heidelberg, GSI and the ExtreMe […]

Flexible tubing Nothing in nature is exempt from investigation by physicists, and the shape of suspended hairs has now come under scrutiny. James Miller and colleagues at Massachusetts Institute of Technology and the Université Pierre et Marie […]
Many brittle materials, such as glass or ceramic tiles, can be broken readily if the surface is cracked first. It might come as a surprise then to find that such materials can be toughened by […]
Non-classical light can be used to circumvent traditional diffraction limits on imaging, and has now been demonstrated to look inside a living cell. To do this, Michael A Taylor of the University of Queensland and colleagues […]
The Medical Service Sample collection Since June 1965, the Medical Service has been responsible for surveying the health of the personnel and for sanitary control. The Staff Rules and Regulations and CERN Safety Codes define medical procedures, […]
