The oily stains accompanying the yellowish rings on the leaves and pods of bean plants are some of the symptoms of the disease known as “Halo blight” – highly important in temperate zones like Spain. The seeds are one of the most important sources of transmission of the pathogen, which means the detection of this bacterium in seeds is one of the most efficient control methods. Nevertheless, agricultural engineer Arantza Rico Martínez has shown, in her PhD thesis, that this blight pathogen cannot be detected in Spain using routine techniques for the certification of bean seeds.
Halo blight is the common name for the disease caused by the bacteria Pseudomonas syringae pv. phaseolicola. One of the aims of this PhD was precisely to genetic characterisation of the bacteria in order to make advances in the control of the disease. To this end, 152 diseased beanstalks, obtained from commercial crop fields between 1993 and 2001.

An international research team including astronomers from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has combined radio telescopes from five continents to prove the existence of a narrow stream of material, a so-called jet, emerging from the only gravitational wave event involving two neutron stars observed so far. With its high sensitivity and excellent performance, the 100-m radio telescope in Effelsberg played an important role in the observations.
In August 2017, two neutron stars were observed colliding, producing gravitational waves that were detected by the American LIGO and European Virgo detectors....
Up to now, OLEDs have been used exclusively as a novel lighting technology for use in luminaires and lamps. However, flexible organic technology can offer much more: as an active lighting surface, it can be combined with a wide variety of materials, not just to modify but to revolutionize the functionality and design of countless existing products. To exemplify this, the Fraunhofer FEP together with the company EMDE development of light GmbH will be presenting hybrid flexible OLEDs integrated into textile designs within the EU-funded project PI-SCALE for the first time at LOPEC (March 19-21, 2019 in Munich, Germany) as examples of some of the many possible applications.
The Fraunhofer FEP, a provider of research and development services in the field of organic electronics, has long been involved in the development of...
For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.
The building blocks of matter surrounding us are atoms and molecules. The properties of that matter, however, are often not set by these building blocks...
