    In der Forschung steht die Universität Würzburg in einem weltweiten Vergleich hervorragend da. Das bestätigt ihr das Leiden Ranking 2013. (Foto: Gunnar Bartsch)

    The University of Würzburg is one of the leading universities in Germany and Europe in terms of research performance. Even in a worldwide ranking, it features among the top German universities. This has been confirmed by the Leiden Ranking 2013 published just now.

    Wissenschaftler haben das Genom des Quastenflossers entschlüsselt. In "Nature" ist diese Arbeit Titelthema. (Grafik: Nature)

    The coelacanth is interesting in many respects: until 1938, this fish was thought to have become extinct; it has changed very little in the past 300 million years; and it is considered a predecessor of the first land creatures. Now scientists have decoded its genome.

    University of Würzburg researchers describe a new form of gene activation in the scientific journal "Cell". They also show how salmonella bacteria thus prevent themselves from being poisoned by too much sugar. The new findings also hold promise for application in bioengineering.

    Elektronenmikroskopische Aufnahmen von Blattoberflächen der Arabidopsis thaliana. Bei hoher Luftfeuchte (80% rh) sind die Stomata deutlich weiter geöffnet als bei 20%. (Bild: Peter Ache)

    If the ambient air is very dry, plants need to protect themselves against excessive loss of water. For this purpose, they close special pores in their leaves. University of Würzburg researchers have explored how plants sense changes in humidity and translate this information into a signal.

    When light hits organic molecules, it triggers processes that are of considerable interest to scientists. But the individual steps of the reaction are very hard to identify. A study group at the University of Würzburg has now accomplished this task – with a sophisticated approach.

    Xiphophorus maculatus, auch Platy oder Spiegelkärpfling genannt. Wissenschaftler haben jetzt sein Genom entziffert und sind dabei auf einige Überraschungen gestoßen. (Foto: Manfred Schartl)

    It is a popular aquarium fish: the platyfish, Xiphophorus maculatus. It is valued by researchers as an important model organism in the search for genetic trigger factors of skin cancer. Together with colleagues from the USA, University of Würzburg biochemist Manfred Schartl has decoded the genome of this fish species.

    Suddenly Magnetic

    Regelmäßig geordnete Muster von Elektronenspins sind dafür verantwortlich, dass nicht-magnetische Zinn-Atome auf einem Siliziumträger plötzlich magnetisch werden. (Grafik: Jörg Schäfer)

    It came as a surprise: If tin atoms are arranged on a silicon substrate in a special way, the material becomes magnetic. University of Würzburg physicists have successfully conducted such an experiment. This research might open up a new way of processing information.

    The blue-light pigment cryptochrome is important in regulating the circadian clock of many organisms. Scientists have now discovered that in the fruit fly Drosophila it also intervenes in the visual process. The central experiments involved were conducted at the University of Würzburg’s Biocenter.

    Chronische Schmerzen unklarer Herkunft sind ein typisches Merkmal der Fibromyalgie. Würzburger Medizinerinnen konnten jetzt zeigen, dass dabei bestimmte Nervenfasern geschädigt sind. (Foto: Benjamin Thorn / pixelio.de)

    Fibromyalgia has a reputation as a mysterious illness: The symptoms are diverse, the causes are unknown and the diagnosis is difficult. For the first time, researchers at the University Hospital of Würzburg now have found clear proof of damage to patients' small fibers.

    In diesem Stadium geht die Larve eines Fuchsbandwurms in den Fuchs über, wenn dieser eine infizierte Maus gefressen hat. In der Mitte der kugeligen Struktur sind schärfer umrissene Krümmungen zu erkennen: Das ist der Hakenkranz, mit dem sich der Bandwu

    For the first time, scientists have mapped the entire genome of four tapeworm species. Their publication in "Nature" magazine reveals new weak spots of the parasites – they seem to be susceptible to standard cancer drugs.

    For quite a few years now, special classes for gifted students have been implemented at grammar schools in the German states of Bavaria and Baden-Württemberg. Researchers from Würzburg, Trier and Erlangen have studied them to determine whether they live up to expectations. The results are definite.

    Christiane Drechsler und Professor Christoph Wanner vom Universitätsklinikum Würzburg haben neue Erkenntnisse zur Behandlung von Dialyse-Patienten gewonnen. (Foto: Robert Emmerich)

    A modified blood protein increases the mortality risk in patients undergoing dialysis treatment. This has been reported by researchers from Würzburg and Boston in the journal "Science Translational Medicine". They also have an idea about how the risk factor might be successfully dealt with.

    T-Lymphozyten sind Zellen des Immunsystems, die Krebszellen zerstören können. Ihre Aktivität spiegelt sich in der Grafik wider, die im rechten Teil den vermehrten Tod der Tumorzellen anzeigt. (Bild Matthias Wölfl)

    Some T cells of the immune system are natural enemies of cancer cells. How they are prepared for their deployment in the organism appears to be very decisive in determining their effectiveness in cancer treatment.

    Trägt man eine einzige Moleküllage organischer Moleküle auf ein metallisches Trägermaterial auf, erhöht sich die Leitfähigkeit des organischen Materials deutlich – haben Physiker der Uni Würzburg jetzt entdeckt. (Grafik Peter Puschnig, Michael Wi

    Organic materials are comparatively poor conductors of electricity. Under certain conditions, however, this can change significantly. University of Würzburg physicists have now experimentally determined how exactly such a change in conductivity works in a two-dimensional layer.
