Bread wheat plants carrying a newly discovered gene that is resistant to economically devastating leaf blotch can reduce the amount of grain lost to the pathogen, according to Purdue University researchers.
The scientists used bread wheat species to find the gene and the markers, or bits of DNA, that indicate presence of the naturally occurring gene. The fungus causes wheat crop damage worldwide with yield losses of 50 percent or more in some places. In the United States the disease is widespread in the Pacific Northwest, the northern Great Plains and the eastern Midwest soft wheat region, and experts estimate annual losses at $275 million.
Results of the Purdue study on resistance to the fungus that causes Septoria tritici leaf blotch are published in the September issue of Phytopathology and appear on the journal’s Web site.

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....

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...
