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.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
