The main objective of this project is the construction of a 30m cable and the terminals needed to connect it to the network, which will be built with the high-temperature superconductor material BSCCO. This is the most advanced cable that exists in terms of distribution (20 kV), since its current value is higher than that obtained up to date, 3200 Amperes RMS, and therefore can transport the electrical strength of 110 MVA, i.e. five times more than a conventional copper cable of the same dimensions. Its construction is planned to be finished before the year 2010. Given that this will be the first superconductor system installed in our country, the SUPERCABLE project also will play a highly significant role in validating this new technology.
The project's framework includes the work of scientists developing new materials based on a second generation of superconductors, known as YBCO, which will be able to transport electricity up to 50 times the capacity of BSCCO cables and 100 times that of copper wires. Moreover, the loss in electricity of second-generation superconductors in comparison to BSCCO cables will be reduced tenfold.
The fact that superconductor technology transports a larger amount of electricity than conventional systems makes it a viable alternative to the efficiency needs of the world's electrical systems, which presently channel 40% of the world's total consumption of energy. Energy demands are expected to double by the second half of this century. Thus the construction of more efficient motors, generators, transformers and superconductor cables would help to satisfy this demand in energy, and at the same time reduce the emission of greenhouse gases.
In fact, transporting electricity with superconductor materials represents important benefits for the environment, since this will contribute to the global reduction of greenhouse gas emissions even if there is an increase in both the global population and the use of energy, especially in developing countries. The use of superconductor energy systems could easily reduce primary energy consumption by 10-15%, with no decrease in user consumption (final energy). This is due to the fact that 60% of the energy presently produced is wasted, which demonstrates that there is yet much to do to improve on energy efficiency. It must be taken into account that for each Gigawatt hour (GWh) of electrical energy saved, 160 tonnes of carbon oxide (COx) and one tonne of nitrogen oxide (NOx) are not emitted. Thus if Catalonia, with a yearly energy consumption of approximately 40,000 GWh, implemented the superconductor technology throughout the country, it could reduce its yearly emissions of carbon oxide by 500,000 tonnes.
The technology based on superconductor materials also increases the security and reliability of network installations, given that these transformers are non-flammable and current restrictions would be easier to apply, which allows for a greater control of the network. The fire generated by the transformers in Barcelona, for example, was precisely the origin of the greatest problem related to the power outage that occurred this past July.
The project is coordinated by Xavier Obradors, researcher at the Institute of Material Science of Barcelona, located at the UAB Research Park. Àlvar Sánchez, lecturer of the UAB Department of Physics, is the director of the UAB team of researchers and works in collaboration with ICREA researcher Du-Xing Chen. Both teams of researchers are working on new superconductor materials, projects that were recently approved by the Nanoselect programme from Ingenio 2010-Consolider, coordinated by ICMAB-CSIC. These research projects are the most significant response from the Spanish Government to the decades of underdevelopment in research in our country, and include the combined force of over sixty researchers with the objective of improving their competitiveness at international level.
The Novare Prizes by ENDESA were awarded first in 2005 and aim to promote different R&D&I activities in scientific areas related to technology and innovation strategies in businesses. The SUPERCABLE project was awarded the prize in "Energy Efficiency", while the other three prizes were awarded to projects from Italy, Chile and Seville. A total of forty proposals were sent from ten different countries.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
