Due to the low level of soil fertility and the limited availability of water, the food situation in Africa is more serious than on any other continent. However, the people meet these challenges with an inventive spirit and much improvisation, in order to utilise all available resources.
Neglected for decades in terms of politics and science, the intensive cultivation of urban areas and the areas surrounding them makes an important contribution with regard to the income and food security of poor population groups, whilst at the same time carrying health and environmental risks. The goal of the “UrbanFoodPlus” project, which is coordinated by the University of Kassel and the Ruhr University, Bochum, is to understand, to boost, and to optimise the various forms of urban farming.Agricultural scientists and soil specialists, working together with economists, wastewater engineers, ethnologists from Göttingen and geographers from Freiburg, develop interdisciplinary approaches to unlocking the full potential of the growing of staple foods and vegetables, and of animal husbandry, in farming niches of urban areas and the surrounding areas. The Federal Ministry of Education and Research (BMBF) will supply 4.3 million Euros over the next three years. This is a portion of the total of 7.5 million Euros that will be made available over a period of five years.
Initial field research takes place in Ouagadougou/Burkina Faso and Tamale/Ghana, and will then be extended to other West African cities. The trials will include small-scale crop-growing experiments, questioning of growers, sellers and administration representatives. There will also be extensive training measures on simple technological innovations, including the use of charcoal both as a water filter and an organic fertilizer.The scheme is divided into several project groups. A working group led by Bürkert is examining biodiversity, food efficiency, flow of materials and certification measures in vegetable production. Prof. Schlecht (University of Kassel and Georg August University, Göttingen), leads a project group that is analysing the efficiency of animal husbandry systems; this includes both the use of stock-feeds, and the utilisation of accumulating dung. Other project groups led by Prof. Marschner and Prof. Wichern (both from the Ruhr University, Bochum) determine the influence of natural fertilizers and household waste water on soil quality and product hygiene, aspects of food security, socio-political frame conditions (Prof. Schareika, University of Göttingen) and possible politico-economical profits derived from the suggested improvements (Prof. Löwenstein, University of Bochum). “Hereby, we want to take sociological and politico-economical consequences into account”, says Bürkert: “How do these urban economic cycles lower the risk of poverty? What part do the women play and how does their task in raising food security influence their role in society? What significance does this type of farming have, especially for ethnic minorities in society?” Prof. Drescher of the University of Freiburg concerns himself with this matter in particular.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
