Helping bridge the gap between photonics and electronics, researchers from Purdue University have coaxed a thin film of titanium nitride into transporting plasmons, tiny electron excitations coupled to light that can direct and manipulate optical signals on the nanoscale. Titanium nitride's addition to the short list of surface-plasmon-supporting materials, formerly comprised only of metals, could point the way to a new class of optoelectronic devices with unprecedented speed and efficiency.

The latest semicustom model from Italian shipyard Sanlorenzo bridges the gap between the Italian yard’s SL88 and SL104 models. The new yacht reflects Sanlorenzo’s efforts to employ some big-boat thinking, with such features as a flybridge that is larger than those of most similar yachts, plus a transom garage that ...

A federal government shutdown would cut short a key NASA field campaign to monitor Arctic ice. For the past three weeks, NASA researchers and crew have been surveying Arctic land and sea ice using specially equipped aircraft. The work is part of a larger project, "Operation IceBridge," designed to fill a gap between NASA's now-defunct ICESat satellite and its replacement, which isn't scheduled to launch until 2016.
