Entangled photons can dramatically reduce the feature sizes possible with lithography. At least, that's what physicists had hoped.
Lithography, the ability to print patterns onto certain materials using light, is one of the enabling technologies of our age. The size of the features that can be defined this way are tiny, limited only by the wavelength of light used to make them, the so-called diffraction limit.
...A heated AFM tip can draw nanometers-wide conductive lines on graphene oxide.
Using a heated atomic force microscope tip, researchers have drawn nanoscale conductive patterns on insulating graphene oxide. This simple trick to control graphene oxide's conductivity could pave the way for etching electronic circuits into the carbon material, an important advance toward high-speed, low-power, and potentially cheaper computer processors.
...Satellite navigation technology is focusing on reducing fuel consumption.
The last few years have seen some satellite navigation systems go from advising motorists of the fastest routes to recommending more fuel-efficient trips. Now Bosch, in Germany, has developed a route-planning system that could squeeze even more fuel savings from a journey by taking into account the car's weight, aerodynamics,...
Software uses images from millions of tourists to suggest ways for visitors to spend their time.
Tourists pondering how to spend their time in a large city could one day get help from a tool developed by researchers at Yahoo. It draws on the database of millions of photos uploaded to the site Flickr to generate detailed itineraries of what sites to visit, and in what order.
...Usage during a recent disaster highlights features that make the service so compelling.
The evidence continues to pile up that Twitter is a news service, not a social network. Of course, Twitter only works as a news service because its news is routed according to social connections--and that's the secret to the service's ability to endlessly issue, digest and re-synthesize news into actionable 140...
