LHC Page 1 2015 was a tough year for CERN’s accelerator sector. Besides assuring delivery of beam to the extensive non-LHC facilities such as the AD, ISOLDE, nTOF and the North Area, many teams also had to work […]
The hadrontherapy community touches base.
The first physics run is envisaged to start early this year.
Lead nuclei collided with an average centre-of-mass energy per pair of nucleons of 5.02 TeV.
Experiments get ready for the HL-LHC.
CAST widens its scientific programme.
Physics laboratories lift the curtain on their backstage activities.
Successful tests for more efficient proton-beam extraction.
CERN’s seat Today, science, technology and innovation are among the most powerful forces driving social change and development. However, what is the actual role that a fundamental science laboratory like CERN can have when it comes to […]

The “Cheshire Cat” This gently smiling cosmic face was released in November 2015 to celebrate the 100th anniversary of Albert Einstein’s theory of general relativity. It is a composite image of a cluster of galaxies seen in visible light […]
The Veil Nebula The observed spectrum of cosmic rays has several puzzling features. For instance, the Alpha Magnetic Spectrometer (AMS) measured an excess of positrons and antiprotons at around 100 GeV. While it is tantalising to interpret such discrepancies […]
Since the first ATLAS results from LHC Run 2 were presented at this summer’s conferences (EPS-HEP 2015 and LHCP 2015) with an amount of data corresponding to an integrated luminosity of approximately 80 pb–1, the LHC has continued to […]
The first phase of collisions after the LHC restart earlier this year provided CMS with data at the novel energy of 13 TeV, enabling CMS to explore uncharted domains of physics. At the end of this […]
Beyond its rich programme in flavour physics based on proton–proton collisions, LHCb opened the door in 2015 to a new domain of physics exploration related to cosmic-ray and heavy-ion physics. Due to its forward coverage, […]
After the restart of the LHC physics programme in June 2015 with world-record proton– proton collisions at √s = 13 TeV, nuclear beams reappeared in the LHC tunnel in November 2015 with subsequent first collisions between 208Pb ions. […]

Light reflection Many fish have metallic-looking reflective scales due to plates of guanine, and it had been thought that the mirror-like finish was all there was to their camouflage, but it turns out that they work more […]
A carcinogenic parasitic worm could do a lot of good one day. Michael J Smout of James Cook University in Queensland, Australia, and colleagues were looking at the oriental liver fluke Opisthorchis viverrini, which infects […]
In 1968, Herbert Fröhlich predicted an analogue of Bose–Einstein condensation in biological macromolecules with a range of vibrational frequencies, which could lead to a macroscopic condensation of energy into the lowest-frequency mode. This would be […]
Chitons – Acanthopleura granulate – are marine molluscs with hard shells. Remarkably, they also have up to 1000 eyes, each a little smaller than a printed period, but there had been doubts as to their degree […]
A breakthrough in distillation uses light to heat an ethanol and water mixture far more efficiently. Naomi J Halas and colleagues at Rice University in Houston put gold–silica nanoparticles into the mixture and shone laser light […]
The origin of the Moon has long been a matter of speculation, with the prevailing idea being that a Mars-sized planet hit the Earth and ejected the material that formed the Moon. The trouble is […]
News from Gargamelle Antineutrino interaction Having obtained evidence for new hadronic constituents [partons] by electromagnetic and strongly interacting probes, the question arises whether they also manifest themselves in weak interactions. Preliminary measurements of the total cross-sections for […]
