Climate friendly fuel cells for hydrogen cars have come one step closer Posted: 21 Jul 2013 01:17 PM PDT Climate friendly fuel cells for hydrogen cars have come one step closer. Researchers have shown how to build fuel cells that produce as much electricity as current models, but require markedly less of the rare and valuable precious metal platinum.

Mirror, mirror on the wall, who has the lowest noise of them all Posted: 21 Jul 2013 01:17 PM PDT Scientists have demonstrated a novel "crystalline coating" technique for producing low-loss mirrors. This technology will further accelerate progress in the development of narrow-line width lasers.

Helping robots become more touchy-feely, literally: Paper-thin e-skin responds to touch by lighting up Posted: 21 Jul 2013 01:17 PM PDT Engineers have created a new e-skin that responds to touch by instantly lighting up. The more intense the pressure, the brighter the light it emits. The material is the first sensor network on flexible plastic that is user-interactive.

Making big 'Schroedinger cats': Quantum research pushes boundary by testing micro theory for macro objects Posted: 21 Jul 2013 01:17 PM PDT Since Erwin Schroedinger's famous 1935 cat thought experiment, physicists around the globe have tried to create large scale systems to test how the rules of quantum mechanics apply to everyday objects. Researchers recently made a significant step forward in this direction by creating a large system that is in two substantially different states at the same time.

Fluid dynamics: Resolving shockwaves more accurately Posted: 18 Jul 2013 07:08 AM PDT A new computational scheme enables more stable simulations of shockwaves in fluids and may be scalable for large engineering designs

Electronics: Graphene makes a magnetic switch Posted: 18 Jul 2013 07:08 AM PDT Tiny nanoribbons of carbon could be used to make a magnetic field sensor for novel electronic devices.
