In today’s world, we become more and more surrounded by cultures that are different from ours. We often find it difficult to understand the other cultures. So, as you can imagine, it is important that ... Read more
In saliva, scientists have found hints that a “ghost” species of archaic humans may have contributed genetic material to ancestors of people living in Sub-Saharan Africa today. The research adds to a growing body of ... Read more
We may be capable of finding microbes in space–but if we did, could we tell what they were, and that they were alive? This month the journal Astrobiology is publishing a special issue dedicated to ... Read more
What is the weight of a proton? Scientists from Germany and Japan have made an important step toward better understanding this fundamental constant. By means of precision measurements on a single proton, they were able ... Read more
The giant slug Limax maximus is native to Europe and Asia Minor but has spread widely, being found in North America, South America, North Africa, South Africa, Australia, New Zealand and other regions. The slug ... Read more
Changes in the brain’s structure that could be the result of depression have been identified in a major scanning study. Alterations were found in parts of the brain known as white matter, which contains fibre ... Read more
A new Yale School of Public Health study found that slot machines, or “one-armed bandits,” may offer a clue to how AIDS programs can better locate persons living with undiagnosed HIV infection. “When you walk ... Read more

Issue 21 contains the following highlights: From EuCARD-2 to ARIES – A new beginning for accelerator R&D in Europe King Abdullah II of […]
Matthew Chalmers Measurements of R(D*) from LHCb (green region), BaBar and Belle compared to the Standard Model prediction (red). The measured values from the three different experiments are all higher than the SM prediction, although the statistical significance is low. Two papers published today in Nature review recent flavour measurements from the LHCb experiment that are […]
The fifth annual Large Hadron Collider Physics (LHCP2017) conference was held last week at Shanghai Jiao Tong University, China. This year there were more participants than ever before: 470 people from universities across the globe. ATLAS presented an interesting set of new results exploiting the high statistics of the combined 2015 and 2016 dataset. Selected highlights are […]
The LHC normally collides protons into each other. If two protons travelling in opposite directions pass very close to one another within CMS or ATLAS, however, photons radiated from each proton can collide and produce new particles. Precision spectrometers situated on either side of CMS experiment, and a similar project taking shape at ATLAS, will […]
Lead ion collisions (F Ronchetti/CERN) Three decades since the first ultra-relativistic collisions were produced at CERN, the field of heavy-ion physics is still a hot topic. High-energy heavy-ion and proton-proton collisions provide a unique system with which to investigate the dynamics of matter in the early universe and to probe fundamental predictions of quantum chromodynamics. […]
(Image: Daniel Dominguez/ CERN) During the past two years there has been a burst of activity in next-to-next-to-leading order (NNLO) calculations to make sure theory keeps up with experiment. Underpinning the prediction of LHC observables are perturbative computations of cross-sections, and NLO corrections have already been calculated for a large class of these processes relevant […]
The 52nd Rencontres de Moriond conference is taking place in La Thuile, Italy, from the 18 March to 1 April. The first week, which ran until 25 March, was devoted to the theme "Electroweak interactions and unified theories", and the second session is based on the theme of “QCD and high energy interaction”. The four main […]
Rickard Ström CLIC test facility (Image: Maximilien Brice/ CERN) This March saw the annual workshop of the Compact Linear Collider (CLIC) at CERN, gathering 220 collaborators from over 26 countries to discuss the latest status of the CLIC accelerator and detector studies. Two collaborations exist to study the feasibility of a future electron-positron linear collider […]
Section of the SESAME Main Accelerator Ring (Image credit: Bennett, Sophia Elizabeth/CERN) The latest issue of Accelerating News has been published and is now available to read online. In this issue: CESSAMag delivering impact – Completed at the end of 2016, the CESSAMag fulfilled all of its objectives. Accelerator Fault Tracking at CERN – AFT […]
Katarina Anthony Determination of the relative strange-to-light quark fraction (Rs). Bands: Present result and its uncertainty contributions from experimental data, QCD fit, and theoretical uncertainties. (Image: ATLAS Collaboration/CERN) New precision measurements of the W and Z boson cross sections show the proton contains more strange quarks than previously believed. The protons collided by the LHC […]
