Aerial picture of the Broadbalk experiment
Scientists at Rothamsted Research in Harpenden (1) and the University of Reading have been able to recover DNA from crop diseases on wheat samples stored as part of a Victorian field experiment (2). Using this DNA, they have discovered how changes in air pollution over the last 160 years have affected fungal diseases on our wheat crops.
The most damaging wheat disease in Europe is leaf blotch, caused by two different fungal species, Phaeosphaeria nodorum and Mycosphaerella graminicola. These species cause the loss of millions of tonnes of grain worldwide each year. Changes in the importance of these two species have been reported in the UK and elsewhere but the reason for this has remained unclear.
Dr Bart Fraaije and his colleagues looked at straw samples archived from the Broadbalk experiment, the world’s oldest, continually-running field experiment, which was set up in 1843 to investigate the effect of fertilisers on crop yields and the soil. They were able to extract fungal DNA from the straw, enabling them to carefully track changes in the populations of the two fungi since Broadbalk’s inception over 160 years ago.

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.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
