This work has studied the effects of lead toxicity in the long term in wild birds populations, determining how this heavy metal causes bone weakening and fracture, provoking therefore a fall in the individual survival of the affected species.
This work has been carried out by Pedro Álvarez Lloret, of the Department of Mineralogy and Petrology of the University of Granada, in collaboration with the University of Georgia (USA), the Karolinska Institute of Stockholm, the Research Institute for Hunting Resources (CSIC) and the Biological Station of Doñana (CSIC). The research work has been supervised by Professor Alejandro Rodríguez Navarro.An ideal record
The researcher has also worked with polychloro-biphenyl (PCB) and TCDD, two organochlorate pollutants used in industrial manufacture processes of plastic and insecticides. Álvarez Lloret has tested the effects of such substance in the bones of wild bird populations of Georgia (USA), for the presence of one of such companies, and has found out that PCB provokes a higher bone maturity if the affected birds, this is, it makes their bones more crystalline, increasing their fragility and making them weaker.
The results of this research work have been published in the journal ‘Environmental Science and Technology’, and will be published shortly in ‘Environmental Pollution’ and ‘Toxicology 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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

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...
