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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
