Still 25 years ago, farmers received the plant nutrient sulphur for free because clean air acts had not come into force by then. Desulphurisation of fumes resulted in a continuously declining atmospheric sulphur input each year so that farmers have to fertilise sulphur regularly in order to warrant a sufficient sulphur supply and crop productivity.
Oilseed rape is particularly sensitive to sulphur deficiency. Oilseed rape is one of Germany's most important crops for the production of bio-energy. Problem: High rainfall will cause exhaustive leaching of plant available sulphate on agricultural soils.
Parallel to the predicted climate change in the next decades, the risk of sulphur deficiency in agricultural crops will increase, so the forecast of geo-ecologist Knut Hartmann and Dr. Holger Lilienthal, both researchers at the Institute for Crop and Soil Science of the Julius Kühn Institute (JKI). They extended and implemented the "MOdel for Predicting Sulphur deficiency (MOPS) into a Geographical Information System (GIS).
By means of the same technology the JKI researchers computed that this year about 38 % of the arable land in Germany is subjected to a high risk of sulphur deficiency. In 60 years (with an expected temperature increase of two degrees Celsius, an increase of winter precipitation by 30 % and a summer rainfall decrease by 30%, the area of land with a high risk of sulphur deficiency will increase to nearly 50%. Without additional efforts in fertilisation and crop protection, the costs of the resulting yield losses for oilseed rape and wheat in Germany, will add up to one billion euros for each crop. For risk assessment MOPS does not only take climatic factors into consideration, but also site-specific, soil-physical and hydrological properties.Explanation Julius Kühn Institute:

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
