The behaviour of photons confined inside three-dimensional cavity superlattices is much more complex than that of electrons in conventional solid-state materials
Measurements of the Leggett-Garg inequality using neutron interferometry emphasize that no classical macroscopic theory can describe reality

Principle of momentum conservation makes it possible to "see" individual alpha particles leaving a micron-scale silica bead
New technique might be used in applications such as targeted drug delivery, micro-robotics and even additive manufacturing
New device exploits the carbon material’s ability to conduct both electrons and protons
Asymmetric effects of surface warming on cloud cover may amplify it, say researchers
Theorists develop new continuity equation to help them visualize the process
