A University of Surrey spin-out company, Cybersense Biosystems Ltd, has developed a portable toxicity screening device. The ROTAS system can be literally wheeled on to a brown field site and carry out field-based screening of contaminated soils and waters and results can be read within minutes. It is especially relevant with the Government’s vision to see more contaminated industrial land made safe for housing.
“The key benefit of ROTAS is its ability to dramatically reduce the cost of site remediation by providing reliable data on site quickly enough that it can be used to influence the management of the project.” says the inventor Dr Tim Hart, Cybersense. Using marine bacteria that naturally emit light (bioluminesce) the Rapid On-Site Toxicity Audit System (ROTAS) is an environmentally sustainable method of analysing toxicity when compared to classic tests on higher organisms. When in a state of metabolic health the bacteria glow more but in the presence of increasing toxicity they glow less.

It has been designed to complement, not to replace chemical analysis.
The information provided by ROTAS is much more powerful than can be obtained by chemical analysis alone and results from its use provide information on the biological effects of contaminants, no matter how complex and ill-defined the pollution is, or what synergistic interactions take place between toxins. The ROTAS system has been specially designed for the analysis of soil samples and is capable of sampling soil in the field in minutes in a very simple to use, disposable piece of kit.

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.
