Two neutron stars collide The origin of some of the heaviest chemical elements is due to rapid neutron capture, but the precise location where this cosmic alchemy takes place has been under debate for several decades. While core-collapse supernovae […]
Storm hits CERN Bubble-chamber film Late in the afternoon of 12 June, a cloudburst lasting an abnormally long time (over an hour) swept down on CERN and left behind flood damage amounting to millions of Swiss francs. Preceded […]
First beam accelerated The Super Proton Synchrotron (SPS) was approved by CERN Council in December 1970. By mid-May 1976 a beam circulated for the first time, although it took another month to get the radio-frequency system to operate […]

The ICARUS detector CERN and Fermilab have a rich history of scientific accomplishment. Fermilab, which is currently the only US laboratory fully devoted to particle physics, tends to favour fermions: the top and bottom quarks were discovered here, […]
An interview with CERN’s Jack Steinberger.
Array could pinpoint the location of astrophysical neutrinos.
Neutrinos could point to a deeper theory of elementary particles.
Results shed light on the ordering of neutrino masses.
T2K and Hyper-Kamiokande advance strong neutrino tradition.
A seminal meeting in 1976 shaped the course of neutrino detectors.
The CERN Neutrino Platform supports global neutrino experiments.
The 1956 experiment that proved neutrinos exist.
Bubble Nebula blown into space This beautiful image, showing an enormous bubble being blown into space by a young star, was chosen to celebrate the 26th anniversary of the Hubble Space Telescope. After so many stunning images captured by this exceptional […]
Delivered luminosity The past few weeks have been a record-breaking period for the LHC, with the machine now delivering long fills with unprecedented luminosity. Following the interruption in late May due to problems with the PS main […]
Our most precise timepieces are atomic clocks, which exploit precise atomic transitions in the microwave and optical bands. Better clocks could come from nuclear transitions, which suffer less from external perturbations, but the only feasible […]
Cosmic muons have been used to image large objects from nuclear reactors to pyramids, thanks to their absorption within thick layers, but until now it has not been possible to image small objects. Now, Istvan […]
Quasiparticles are common in condensed-matter physics, but now it is possible to do collider experiments with them. Fabian Langer of the University of Regensburg in Germany and colleagues used femtosecond optical pulses to create excitonic […]
The largest mathematical proof to date is 200 terabytes in length and unlikely to be checkable by any human being. Marijn Heule of the University of Texas at Austin and colleagues considered the boolean Pythagorean-triples problem, […]
Sneeze on film High-speed imaging has enabled researchers to directly observe the mechanisms of droplet formation during sneezing. The study reveals that the break up of the fluid into droplets continues to occur outside of the respiratory tract […]
Learning organisms Learning is not only the preserve of multicellular organisms with central nervous systems. According to a new study, much simpler organisms are also up to the task. Audrey Dusstour of Toulouse University in France and […]
Production record au LHC Des nouvelles de CMS à la conférence LHCP ATLAS guette les désintégrations rares de mésons B en paires de muons LHCb réalise une nouvelle mesure de l’oscillation du Bs ALICE sépare le chaud du froid L’ESO signe le plus gros contrat d’astronomie sol au monde Une expérience du CERN dessine un climat préindustriel plus nuageux que prévu AWAKE reçoit son premier faisceau Apprendre sans neurones Des fusions d’étoiles à neutrons à l’origine des éléments les plus lourds
First beam of particles CERN’s pioneering AWAKE facility, which aims to drastically reduce the scale of particle accelerators, received its first beam on 16 June. The milestone signals the next stage of commissioning for the novel experiment, which aims […]
Soluble-particles concentration New results reported in two papers in Nature from the CLOUD experiment at CERN imply that the pre-industrial climate may have had brighter and more extensive clouds than previously thought, sharpening our understanding of the […]
Bigger light-collecting area The European Extremely Large Telescope (E-ELT) will be the largest optical/near-infrared telescope in the world, boasting a primary mirror 39 m in diameter. Its aim is to measure the properties of the first stars and galaxies […]
In the early stages of a high-energy collision, high-pT partons can be created, before producing sprays of hadrons that are measured experimentally as jets. Not only do high-pT partons carry information about the parton scattering […]
The LHCb experiment has recently made the most precise measurement yet of the asymmetry in oscillations between the matter and antimatter versions of Bs mesons. The measurement exploits the full LHCb data set recorded during […]
The decays of the B0s and B0 into muon pairs represent an important test of the Standard Model. Such decays take place through a flavour-changing neutral current process, which occurs only through loop diagrams and […]
