“Seed quality is determined by highly complex interactions between biochemical, biophysical and molecular processes within the seed, which are only very poorly understood” explains Ilse Kranner, Professor of Plant Physiology at the Austrian University of Innsbruck, who is the coordinator of the EU-project EcoSeed. In this project, three crop species, barley, sunflower and cabbage will be studied together with the model plant Arabidopsis, to see how drought and elevated temperatures suffered by the mother plant, impact upon seed quality. As a next step, the scientists want to find out how changes in temperature, humidity and oxygen concentrations during storage further affect seed viability, storability, and seedling vigour.The knowledge gained from the detailed study of the above four plant species will then be transferred to wild plant species to the benefit of conservation projects. Eleven renowned European teams participate in the EcoSeed project. Among them are the Seed Conservation Department of the Royal Botanic Gardens, Kew, maintaining the largest ex situ genebank for wild plant species globally, and the Federal ex situ Genebank of Germany, the IPK Gatersleben, which is the largest crop genebank in the EU. “EcoSeed combines aspects of food security and conservation, and we are lucky to have top-class scientists in the consortium” says Ilse Kranner.

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...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
