A computer has finally beaten a human at the ancient board game Go – and rather dramatically. Developed by Google DeepMind in London, the program AlphaGo uses deep neural networks to get around the traditional […]

BEBC getting ready to operate BEBC control room First tracks were taken in the 3.7 m Big European Bubble Chamber (BEBC) in March. A hydrogen leak that interrupted the tests was repaired quickly and operation continued up to 2.6 T. […]

Experiment explanation Interest in CERN has evolved over the years. At its inception, the Organization’s founding member states clearly saw the new institution’s potential as a centre of excellence for basic research, a driver of innovation, a […]

Social insects have castes – queens, workers, and soldiers – and the origin of this structure has been tracked back to ancient termites. Michael Engel of the University of Kansas in Lawrence and colleagues found […]

Remarkably, the Venus flytrap can count to five. Erwin Neher of the Max Planck Institute for Biophysical Chemistry in Göttingen, Germany, and colleagues, recorded electrical impulses from the plant in response to one to 60 touches. […]

If you are unhappy about Pluto losing its official status as a planet, the good news is that there may be a 9th one that we’ve missed so far, orbiting out beyond Pluto with a […]

The idea of obtaining distance by integrating speed with respect to time is an elementary one today for anyone who has studied high-school calculus, but it now appears that the idea was used by astronomers […]

Installing wall current monitors The LHC, last among all of CERN’s accelerators, is resuming operation with beam while this issue goes to press. The year-end technical stop (YETS) started on 14 December 2015. During the 11 weeks of scheduled maintenance activities, […]

A new supernova is more than twice as luminous as any seen before, at its peak being brighter than 570 billion suns. Subo Dong of Peking University in Beijing, China, and colleagues found the supernova – […]

Data suggest that trees break at a critical wind speed of about 42 m/s, regardless of the characteristics of any given tree. This has now been explained by Christophe Clanet of LadHyX, of the Ecole Polytechnique […]

Incandescent bulb A new approach to incandescent bulbs promises to beat LEDs for efficiency. Ognen Ilic and colleagues at MIT replaced the traditional light-bulb filament with a flat tungsten ribbon. They then coated glass sheets with a […]

In December last year, the 3 GeV Taiwan Photon Source (TPS) of the National Synchrotron Radiation Research Center (NSRRC) stored 520 mA of electron current in its storage ring, and gave the world a bright synchrotron light […]

Signals from CLAWS On 10 February, the SuperKEKB electron–positron collider in Tsukuba, Japan, succeeded in circulating and storing a positron beam moving close to the speed of light through 1000 magnets in a narrow tube around the 3 km circumference of […]

Machine learning, also known in physics circles as multivariate analysis, is used more and more in high-energy physics, most visibly in data analysis but also in other applications such as trigger and reconstruction. The community […]

The CMS collaboration is continuing its hunt for signs of supersymmetry (SUSY), a popular extension to the Standard Model that could provide a weakly interacting massive-particle candidate for dark matter, if the lightest supersymmetric particle […]

Exploiting the data collected during November 2015 with Pb–Pb collisions at the record-breaking energy of √sNN = 5.02 TeV, ALICE measured for the first time the anisotropic flow of charged particles at this energy. Fig. 1. Relativistic heavy-ion collisions are […]
