A gold plated window as the transparent electrode for organic solar cells is now a reality thanks to a team of researchers from the University of Warwick in the UK. The upshot of this development, apart from its innovation, is that it could be relatively cheap because the gold used is just 8 nanometers thick.

When it comes to dreaming about diamonds, energy efficiency and powerful information processing aren't normally the thoughts that spring to mind. Unless, of course, you are a quantum physicist looking to create the most secure and powerful networks around.

Read moreWater molecules characterize the structure of DNA genetic material
Water molecules surround the genetic material DNA in a very specific way. Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have discovered that, on the one hand, the texture of this hydration shell depends on the water content and, on the other hand, actually influences the structure of the genetic substance itself. These findings are not only important in understanding the biological function of DNA; they could also be used for the construction of new DNA-based materials.

Read moreNanotechnology aids in ash analysis for volcano no-fly zones
Planes were grounded all over Europe when the Eyjafjallajokull volcano erupted in Iceland last year. But no one knew if the no fly zone was really necessary. And the only way to find out would have been to fly a plane through the ash cloud - a potentially fatal experiment. Now a team of researchers from the University of Copenhagen and the University of Iceland have developed a protocol for rapidly providing air traffic authorities with the data they need for deciding whether or not to ground planes next time ash threatens airspace safety.

Researchers have achieved a breakthrough in quantum communications and computing using a teleporter and a paradoxical cat. The breakthrough is the first-ever transfer, or teleportation, of a particular complex set of quantum information from one point to another, opening the way for high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via quantum communications networks.
