Analysis of a diverse range of wheat varieties within the HEALTHGRAIN project of the European Union has shown substantial variation (up to four-fold) in the content and composition of these components. Furthermore, a significant proportion of this variation, particularly for dietary fibre content, is highly heritable and hence can be exploited by plant breeders to produce new types of wheat with enhanced health benefits.
Genomics tools developed enabled to identify markers for dietary fibres, tocopherols and sterols. These markers can be used in breeding programmes to cumulate genes for enrichment of bioactive compounds, particularly those present in exotic, unadapted germplasm, for adaptation in lines or varieties useful in practical agriculture. Molecular marker assisted selection was used to develop f.ex. wheat varieties with high amylose content.
A major limitation to exploiting this variation is the lack of rapid and affordable analytical systems. New tools (including NIR calibrations, antibodies and molecular markers) are therefore being developed which are appropriate for use by plant breeders, grain traders and processors and the food industry. The programme is therefore providing benefits to consumers, plant breeders and the wheat processing chain.
The EU Integrated Project HEALTHGRAIN:_ The HEALTHGRAIN project has substantially strengthened the scientific basis for a new generation of cereal based products with enhanced health benefits. The project also has formed a network of research organizations, industries and organizations communicating to consumers that will continue as the HEALTHGRAIN Forum. It has been coordinated by Academy Professor Kaisa Poutanen from VTT Technical Research Centre of Finland. Results of the project will be presented in the HEALTHGRAIN Conference on May 5-7 in Lund, Sweden: www.healthgrain.org
Rothamsted Research: Rothamsted Research is centred in Harpenden Hertfordshire and is the largest agricultural research institute in the country. The mission of Rothamsted Research is to be recognised internationally as a primary source of first-class scientific research and new knowledge that addresses stakeholder requirements for innovative policies, products and practices to enhance the economic, environmental and societal value of agricultural land. The Applied Crop Science department is based at Broom's Barn, Higham, Bury St. Edmunds. North Wyke Research is located near Okehampton in Devon. See http://www.rothamsted.bbsrc.ac.uk/
BBSRC: BBSRC is the UK funding agency for research in the life sciences. Sponsored by Government, BBSRC annually invests around £450 million in a wide range of research that makes a significant contribution to the quality of life in the UK and beyond and supports a number of important industrial stakeholders, including the agriculture, food, chemical, healthcare and pharmaceutical sectors. For more information see: http://www.bbsrc.ac.uk
INRA Clermont-Ferrand: INRA-University joint unit research of Clermont-Ferrand is the core laboratory for Genetics and Genomics research on wheat in France and coordinates the public research network, with strong links with private companies associated in the "Cereal valley" competitivity Cluster. It is currently cochairing the International wheat sequencing consortium ad International Triticeae Mapping Initiative. It develops researches on structural genomics (evolution of gene space, polymorphism and management of genetic resources), functional genomics (identification of key genes controlling tartget traits such as yield, stress tolerance and grain composition) and integration of knowledges into an applied breeding programme for sustainable agriculture.

Agricultural Research Institute (ARI) of HAS, Martonvasar, Hungary: The Institute covers a wide spectrum of crop science research. It became a regional research centre in the frame of the EU FP7 AGRISAFE project. The Martonvasar phytotron, the largest in Europe is an excellent tool for studying genotype x environment interactions, the effects of climate change on agricultural crops. The aims of the cereal gene bank research are the preservation and improvement of genetic variability, genotyping and phenotyping germplasm endemic in this region, thereby contributing to cereal breeding research for different nutritional quality traits and for different growing environments including high-, low input and organic production.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
