Nano machines that could put together molecules mechanically one by one, also called molecular assemblers, typically have been the stuff of futurists. Now, Salma Kassem and colleagues at the University of Manchester in the UK […]

The new particles Sam Ting 1974 has been one of the most fascinating years ever experienced in high-energy physics. Anyone in touch will be well aware of the ferment created by the recent news from Brookhaven and […]

The Lazy Universe: An Introduction to the Principle of Least Action By Jennifer Coopersmith  Oxford University Press Coopersmith With contagious enthusiasm and a sense of humour unusual in this kind of literature, this book by Jennifer […]

Researchers have taken an important step towards 3D printing of high-strength metals. Despite the huge growth of 3D printing in recent years, the way metal grains are printed and incorporated can lead to microstructures with […]

Baby MIND In mid-October, a neutrino detector that was designed, built and tested at CERN was loaded onto four trucks to begin a month-long journey to Japan. Once safely installed at the J-PARC laboratory in Tokai, the […]

Sneezing patterns African wild dogs, Lycaon pictus, a highly social and co-operative species, vote by sneezing, according to findings by Reena Walker of the Botswana Predator Conservation Trust and Brown University in Providence and colleagues. The team […]

In explaining the diversity of rotation curves measured for spiral galaxies, the simplest cold-dark-matter (CDM) models run into difficulties. It appears, however, that self-interacting dark matter (SIDM) does better. Ayuki Kamada of the University of […]

Spider silk famously has excellent mechanical properties, having both high strength (around 1.5 GPa) and toughness (around 150 J/g). Nicola Maria Pugno of the University of Trento and colleagues have now found a way to dramatically improve […]

Zero viscosity Superfluidity, like superconductivity, is typically thought of as needing very low temperatures that alter the fundamental quantum-mechanical behaviour of materials. Surprisingly, Giovanni Lerario of CNR NANOTEC Institute of Nanotechnology in Italy and colleagues now report […]

The CMS experiment has added another piece to the Higgs boson puzzle, reporting evidence that the Higgs decays to a pair of b quarks. In the Standard Model (SM) the Higgs field couples to fermions, […]

Recently, the ALICE collaboration measured the elliptic flow of J/ψ mesons with unprecedented precision in lead–lead (Pb–Pb) collisions and, for the first time, also in proton–lead (p–Pb) collisions. While the results at low transverse momentum […]

Mass distribution The LHCb collaboration has published the result of precision mass and width measurements of the χc1 and χc2 charmonium states, performed for the first time by using the newly discovered decays χc1 → J/ψ μ+μ– and χc2 → J/ψ μ+μ–. Previously […]

CLIC X-band Advanced linear-accelerator (linac) technology developed at CERN and elsewhere will be used to develop a new generation of compact X-ray free-electron lasers (XFELs), thanks to a €3 million project funded by the European Commission’s Horizon 2020 […]

In position Researchers at the Cryogenic Underground Observatory for Rare Events (CUORE), located at Gran Sasso National Laboratories (LNGS) in Italy, have reported the latest results in their search for neutrinoless double beta-decay based on CUORE’s first […]
