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 […]

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 […]

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 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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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, […]
