Being involved as it is in the field of micro and nanotechnologies, AZTI-Tecnalia is currently taking part in the validation of microsystems for their application in foodstuffs, collaborating in the development of improvements in the “BIO” detection system. Thus, microsystems for their use in the rapid detection of pesticides and pathogens, amongst others.
As regards pesticides, an assessment of a microsystem for determining atrazine and 2,4,6- trichlorophenol in wine samples was presented. Likewise, and with reference to the detection of pathogens, the work undertaken with a prototype for a portable sensor capable of simultaneously detecting Salmonella spp. and Listeria monocytogenes in fish and dairy products was presented – a system which considerably reduces the detection time for these infections.
Research work carried out on a microsystem for the quality control of foodstuffs and food safety, particularly fish, was presented. The fish sector above all requires sensitive methods that are able to report on the state of conservation of their products. Thus, part of the research work focused on the determination of volatile substance produced by fish products during their storage and on defining molecular markers capable of indicating the useful or end-life of the same.
Finally, AZTI-Tecnalia informed about the applications and risks of micro- and nanotechnologies in the food sector. It is predicted that these technologies, still emerging ones in the sector, will provide innumerable advantages in the quality control of foodstuffs and food safety (design and development of intelligent packaging, new intelligent systems of traceability, development of nanoparticles with bactericidal action, new functional foodstuffs, etc). Nevertheless, there is considerable social awareness and concern regarding the use of nanomaterials in foods, due to the scant information provided on their possible effects on human health. This is why the scientific community is focusing their research work on the effects and toxicity of these nanomaterials, publishing new works and creating databases. In consequence, AZTI-Tecnalia is currently working on the development of a rapid toxicological test based on the zebra fish animal model, in order to find out the effects, in the short and the long term, of nanomaterials and nanoparticles that have applications in foodstuffs.

In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...
