In order to avoid possible fraud in labelling, a number of different technologies have been developed in recent years to comply with the regulations of the European Union (Regulation CE No 104/2000) indicating the need to label fisheries products with their scientific name so as to ensure traceability throughout the chain of processing and marketing.
Within the European SEAFOODplus project, AZTI- Tecnalia has launched a DNA database scheme, free of charge. This database contains more than 700 references for the mitochondrial DNA sequences of the most important commercial species in Europe, including Gadidae family (e.g. cod), the Thunnus genus (e.g. tuna) and Merlucciidae family (e.g. hake).
The database is a practical tool for validating techniques of identification in species of fish. It is based on DNA analysis by means of a dynamic system that enables the simplification of the handling of DNA sequences for establishing similarities and finding polymorphisms, etc. Thus, each DNA reference sequence is characterised (with a marker at the 3’ and 5’ ends) facilitating its location on the genome.
Moreover, it is a useful source of information for developing new techniques of identification based on DNA analysis, enabling the comparison of results obtained in various laboratories.

Yersiniae cause severe intestinal infections. Studies using Yersinia pseudotuberculosis as a model organism aim to elucidate the infection mechanisms of these...
Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
