The Department of Parasitology of University of Granada (Universidad de Granada [http://www.ugr.es]), and the researcher Isabel Rodríguez González have submitted a thesis that analyses for the first time new isolated parasites: Leishmania and Trypanosoma in Peru, Mexico and Spain. These parasites are responsible for diseases such as Chagas – which affects at least 18 million people in South America – and Leishmaniasis – which affects around 12 million people throughout the world. The World Health Organization has recognised these diseases as a public health problem.
This study has compared these parasites with reference strains, by using biochemical and molecular techniques. Thanks to these techniques, the researcher was able to identify which groups these isolated parasites belong to.
No medical treatment
The researcher pointed out: “There is no specific treatment yet. Medicines that are used may have serious consequences. Their efficiency varies, because they are long and expensive treatments often associated with toxic effects.” Some species of these parasites need no treatment, others do.
“If we want to find a specific treatment, the first step we have to take is to correctly identify these species.” This is also of epidemiological value to understand parasite distribution, and is aimed at discovering specific control measures.
Another important feature of the study is the usefulness of one of the techniques used: PCR (Polymerase Chain Reaction). It is a relatively simple technique, cheap in comparison with others. PCR makes it possible to identify the isolated parasites in field studies.
The results of the study have already been published in some of the most important scientific journals in the field of Parasitology, such as Parasitology Research, Experimental Parasitology or FEMS Microbiology Letters.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
