This last point is what we would call pollution and it is easy to detect now thanks to the advances by the doctoral thesis recently presented in the Department of Edaphology and Agricultural Chemistry of the University of Granada (Universidad de Granada [http://www.ugr.es]).
The study "Propuesta de criterios para determinar los valores de niveles característicos de metales pesados en suelos y sedimentos a partir de métodos entrópicos" (A criteria proposal to determine the values of characteristic levels of heavy metals in soils and sediments from entropic methods), prepared by Rafael Bellver Mancheño, under the supervision of teachers Juan Antonio Fernández García and Mariano Valderrama Bonnet, goes deeply into the knowledge of soil genesis in Eastern Andalusia, in an area of 350 square kilometres.
Most of the times, heavy metals can be naturally found in soils and sediments, but the study detects a series of points where it would be advisable to reduce or remove certain heavy metals which are gradually increasing. According to Bellver Mancheño, this topic can generate an excessive social alarm due to the association, sometimes mistaken, between the presence of heavy metals and pollution.
With the method suggested by the UGR [http://www.ugr.es], it is possible to observe the development of the concentration of the different metal elements studied. To this extent, new methods for data analysis have been designed to discuss the results of chemical analysis and compare them to other previously obtained in the same field of study.

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.
