We often hear that technology is advancing so fast that society cannot keep up. But in reality, social change is intimately linked to technology changes, and that expectations of what technology can bring changes in intensity.

Even in countries with high gender equality, sex differences in math and reading scores persisted in the 75 nations examined by a new study. Girls consistently scored higher in reading, while boys got higher scores in math, but these gaps are linked and vary with overall social and economic conditions of the nation.

The precise methodology of Richard Feynman's famous double-slit thought-experiment -- a cornerstone of quantum mechanics that showed how electrons behave as both a particle and a wave -- has been followed in full for the very first time.

Large parts of our lives are now being monitored and analysed by computers. Log on to Amazon and intelligent data analysis software can recommend a selection of books you might like to read. Far from being a sinister intrusion into people's privacy, the purpose of these systems is to improve our lives, experts say.

Many discoveries in physics came as a big surprise -- for example the phenomenon, that some materials loose almost all their electrical resistance at low temperatures, or that others become superconductors at unexpectedly high temperatures. In the past it was mainly due to theoreticians to develop models explaining these unusual properties. Unfortunately it is not possible to have a direct look into a solid state crystal and follow up the motion of charge carriers as this process happens at extremely short time and length scales. Scientists have now observed the coherent propagation of single spin excitations in an ultracold quantum gas of strongly correlated atoms.

New multicore optical fibers have many times the signal-carrying capacity of traditional single-core fibers, but their use in telecommunications has been restricted because of the challenge in splicing them together. Now, a new technique offers an automated method for aligning and splicing multicore fibers, allowing engineers to take manual splicing out of the lab and into an automated production line.
