Solid objects generally produce a splash upon entering water. Surprisingly, a small change in the surface chemistry of an object can turn a big splash into an inconspicuous disappearance and vice versa.
A semiconductor device that integrates electron spin injection, transport, modulation and detection in a single structure provides an important step in versatility for both fundamental research and practical spintronic applications.
The ability to build electronic structures from graphene sheets has progressed significantly. Two theoretical studies suggest that graphene nanostructures could be used for quantum information processing.
It's more than twenty years since our journey towards a theory of high-temperature superconductivity began, but we've yet to reach our destination. The road ahead is winding, but there are new data and ideas to guide us.
Despite 15 years of turbulent change, 'brain drain' and a shortage of research funds, Russian science has survived, although in a much diminished state. International investment and collaboration over the next ten years could bring it back from the brink.
