Screws used in surgical operations are often made of titanium. They usually have to be removed after a while or replaced by new ones. A new biomaterial makes this unnecessary. It promotes bone growth and is biodegradable. Source: Fraunhofer Gesellschaft read more
So called dendritic cells patrol in our bodies 24/7 searching for indications for tumors or infections. As soon as they make a find, they activate Killer-T-Cells and thereby initiate an immune defense reaction. Researchers from the University of Bonn and their colleagues at the Universities of Düsseldorf, Hamburg, Utah (USA) and Melbourne (Australia) have now discovered how exactly this occurs: their findings could be of use for the development of better vaccines. They will be published in the next issue of the Nature Immunology journal (doi:10.1038/ni.1848). read more

LONDON/ WUERZBURG. Microscopical insights into a failing heart – scientists found out that receptors on the surface of pathological cardiac muscle cells leave their location and hence produce adverse signals. read more
Those who search for a key fitting into the lock need to have a spatial mental image of it. This also holds true for researchers having to grasp shapes and structures of molecules in order to design new medication. For this purpose, bio-computer-scientists in Saarbrücken and Tübingen have developed the freely available software Ballview. read more
New possibilities - PlasTEP: The new anti-pollution plasma project is under way Over recent years, public opinion has focused on the issue of environmental protection since progressive degradation of the environment, resulting from increased generation of pollutants and wastes is the price for the rapid development of human civilization of the 20th century. read more
An international team of researchers led by Dr. Udo Bach at the Monash University in Australia has come up with an innovative method to improve the performance output of the next generation of solar cells. read more

The utilization of germanium as the basic material for electronic switches would enable the production of even faster chips with a higher degree of integration. However, there is a number of problems yet to be solved. Until recently it has not been possible to manufacture a certain type of transistors (NMOS) based on germanium with a technologically interesting degree of integration. Two innovative procedures, successfully deployed by scientists from the FZD and their international colleagues, take remedial action here. read more
The Göttingen Neuroscientist Hiroshi Kawabe has cleared up a process entirely overseen so far, which enables neurons in the brain to grow and form complex networks. The study now published in the Neuron journal demonstrates that a certain enzyme that should be regulating the deconstruction of protein units, in fact has an entirely unexpected function: it directs the construction of the cytoskeleton and thereby ensures that the neurons are able to grow axons required for signal conduction in the brain.
