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’.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
