    Nanodomänen in der Membran der genetischen Modellpflanze Arabidopsis thaliana, hier sichtbar gemacht mit hochauflösender Mikroskopie. Die Domänen erscheinen als scharf abgegrenzte Bereiche (rot, links). In ihnen läuft unter anderem der ABA Signalweg a

    In dry conditions, certain areas of the plant cell membrane are subject to significant changes. For the first time, scientists have made these so-called nanodomains visible under the microscope, investigating how they changed.

    Wissenschaftler der Uni Würzburg haben eine Mutation entdeckt, die bei den Betroffenen die Fanconi-Anämie auslöst. Das Gen steuert normalerweise spezielle DNA-Reparaturmechanismen. (Foto: Gerd Altmann / pixelio.de)

    Cells are generally able to repair damage to the genome by themselves. However, a defect in the genes controlling such repair mechanisms usually leads to severe diseases. University of Würzburg scientists have now discovered mutations of an unexpected gene in the case of Fanconi anemia.

    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.

    Eine Sequenz ultrakurzer Laserpulse (links) führt zur chemischen Reaktion eines Merocyanin-Farbstoffs (Mitte), die detailliert mittels mehrdimensionaler Spektroskopie analysiert werden kann (rechts). Grafik: Martin Kullmann, Universität Würzburg

    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.
