Gold(en) boost for organic solar cells

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.

New nanobead approach could revolutionize sensor technology

Researchers at Oregon State University have found a way to use magnetic "nanobeads" to help detect chemical and biological agents, with possible applications in everything from bioterrorism to medical diagnostics, environmental monitoring or even water and food safety.

Water 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.

Nanotechnology 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.

Molecular movements of neural transporters unveiled

A team of scientists from Columbia University College of Physicians and Surgeons and Weill Cornell Medical College has shed light on the molecular workings of transporter proteins, molecular machines embedded in the cell membranes of neurons that modulate the transfer of signals between cells and recycle neurotransmitters.

First-ever teleportation of a particular complex set of quantum information

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.
